used to indicate correspondence between referenced elements . fig1 illustrates a roller apparatus 100 , an electronic device 135 and a film 150 . the roller apparatus 100 may be used to apply the film 150 to a surface of the electronic device 135 . the film 150 may protect the electronic device 135 from damage ( e . g ., scratches ) and / or smudges . as shown , the roller apparatus 100 may have a width wider than the width of the electronic device 135 and the film 150 . in this manner , the roller apparatus 100 may be configured to apply films of varying sizes onto devices of varying sizes . in addition , the roller apparatus 100 may be configured to apply the film 150 to a device with a curved surface ( not shown ). in one embodiment , the roller apparatus 100 may be increased in size or decreased in size ( along with the appropriate proportions ) for usage with significantly larger films and devices ( e . g ., a tablet pc ). fig2 a illustrates one embodiment of a roller apparatus 200 . as shown , the roller apparatus 200 may include a roller base or carriage 205 , a first or front roller 210 , a second or back roller 215 , a mid - bar 220 , a first or left splitter 225 and a second or right splitter 230 . the roller base 205 may be constructed out of a rigid material such as a plastic , a metal , a wood and the like . the roller base 205 is configured to provide structural support for the roller apparatus 200 . in addition , the roller base 205 may be sized to be easily manipulated and graspable by a user &# 39 ; s hand . the roller base 205 may be configured to hold the first roller 210 in place and allow the first roller 210 to “ roll ” or rotate about a longitudinal axis created by the roller base 205 . in one example , the roller base 205 may be structured to include a first rod member ( not shown ) spanning the entire length of the first roller 210 , thereby forming an axis for the first roller 210 to rotate about . the first roller 210 is configured to rotate and apply physical pressure on a film ( e . g ., film 150 of fig1 ) in operation . the first roller 210 may be separated from the mid bar 220 by a first roller gap 235 and may be further separated from the first splitter 225 and the second splitter 230 by a splitter gap 245 . these gaps ( e . g ., the first roller gap 235 and the splitter gap 245 ) may serve as structural openings to allow the first roller 210 to rotate freely . the second roller 215 may be a redundant pressure applicator and may be substantially the same size as , and substantially parallel to the first roller 210 . the first roller 210 and the second roller 215 may be separated by a mid bar 220 . the mid bar 220 may connect the two ends of the roller base 205 and provide the entire roller apparatus with stability . in addition , a gap 240 may exist between the mid bar 220 the second roller 215 to allow the second roller 215 to rotate freely . the first splitter 225 and the second splitter 230 may lie along the same plane and may be slightly curved . the splitters 225 and 230 may be configured to be rigid and may function to separate an adhesive portion of a film ( e . g ., film 150 ) from its non - adhesive backing during the application process . fig2 b is a perspective view of the roller apparatus 200 . in one embodiment , the roller apparatus 200 may be configured to function as a film applicator for phone - sized devices and may have a length of 1 - 2 inches , a width of 2 - 4 inches , and a height of 0 . 5 - 1 inch . in one embodiment , the roller apparatus 200 may be configured to function as a film applicator for tablet - sized devices and may have a length of 1 - 5 inches , a width of 8 - 12 inches , and a height of 0 . 5 - 2 inches . other dimensions are also possible depending on the size of the device to be protected and / or depending on the size of the film to be applied . fig2 c is a side perspective view of the roller apparatus 200 . as shown , the rollers 210 and 215 may include inner cores 255 and 260 , respectively . in addition , the rollers 210 and 215 may include outer cores 265 and 270 , respectively . in one embodiment , the outer cores 265 and 270 may be configured to “ flatten ” at the point of contact and thereby providing pressure in a more uniform and distributed manner , efficiently eliminating air bubbles . the outer cores 265 and 270 may be configured to return to its original configuration when not pressed to the surface of the device ( e . g ., electronic device 135 ). in one embodiment , the mid bar 220 may be curved or straight , and may have a length substantially equivalent to the length of the rollers 210 and 215 , thereby joining the two ends of the roller base 205 . additionally , the mid bar 220 may be configured to have a width shorter than a diameter of the outer cores 265 and 270 . in this manner , the mid bar 220 provides structural support to the roller apparatus 200 without contacting the film ( e . g ., film 150 ) or the device ( e . g ., electronic device 135 ) during the application process . in one embodiment , the splitters 225 and 230 may be located adjacent to the first roller 210 . the splitters 225 and 230 may jut inward from the roller base 205 so as not to extend the footprint of the roller apparatus 200 . in addition , the splitters 225 and 230 may function to remove the non - adhesive backing from the adhesive portion of the film ( e . g ., film 150 ) during an application process . while shown to be two , distinct parallel elements , the splitters 225 and 230 may be joined together ( e . g ., by extending the splitters 225 and 230 towards one another ) and / or may be constructed as one piece . the splitters 225 and 230 may be constructed out of any material with sturdiness sufficient enough to separate and remove the adhesive portion of the film ( e . g ., film 150 ) from a non - adhesive backing . in one embodiment , the splitters 225 and 230 may be curved and formed in the shape of a “ c ” as shown in fig2 c . the curvature (“ c ” shape ) of the splitters 225 and 230 may advantageously increase the ease of by which the non - adhesive backing from the adhesive portion of the film ( e . g ., film 150 ) is removed . however , other configurations are possible . for example , a “ letter opener ” configuration where the splitters 225 and 230 include tapered edges may be utilized . while described in fig2 c to have inner cores 255 and 260 , certain embodiments of the roller apparatus 200 might not include inner cores 255 and 260 . in one embodiment , the roller apparatus 200 may comprise any number of rollers ( e . g ., one roller — by removing the second roller 215 , three rollers — by extending the width of roller base 205 and adding a third roller , etc .) in one embodiment , the roller apparatus 200 may comprises two parts , a roller ( e . g ., the first roller 210 ) and a base ( e . g ., the roller base 205 ), wherein the base may include an integrated mid bar ( e . g ., mid bar 220 ) and a splitter ( e . g ., splitters 225 and 230 ). fig2 d , 2 e and 2 f show other various views of one embodiment of the roller apparatus 200 . fig2 g illustrates a cross - sectional view of the first roller 210 . all principles of the first roller 210 discussed herein may be equally applicable to the second roller 215 . as shown , the outer core 265 may wrap the entirety of the inner core 255 . in addition , the inner core 255 may have a substantially smaller diameter than the outer core 265 . in one embodiment , the inner core 255 may be constructed out of a rigid material such as metal , wood , a hard plastic , etc . the outer core 265 may be constructed out of a different , non - rigid or semi - rigid material such as a rubber , a soft plastic or a polymer . in one embodiment , the material used to construct the inner core 255 may be the same as the material used to construct the outer core 265 . however , in one embodiment , the densities of the material may be different . for example , the materials used to construct the outer core 265 may be less dense and / or have a lower durometer rating . by having a softer outer core 265 , the roller apparatus 200 may be able to press the film ( e . g ., film 150 ) onto the device ( e . g ., electronic device 135 ) without causing surface damage . the softer material of the outer core 265 also helps to more effectively and advantageously remove the air bubbles between the film 150 and the screen of the electronic device 135 . turning to fig3 a , an operation of the application process will now be discussed . as shown , a user may apply part of an adhesive portion 355 of a film 350 by removing a part of the backing portion 360 of the film 350 and lining up the adhesive portion 355 to a surface ( e . g ., a screen ) of an electronic device 335 . the roller apparatus 300 might not be used in this initial set - up step . next , as shown in fig3 b , the roller apparatus 300 may be configured and placed into position for operation . more particularly , the roller apparatus 300 may be placed on top of the film 300 and electronic device 335 with the splitters 325 and 330 between the adhesive portion 355 and the backing portion 360 . once the roller apparatus 300 is in position , the user may place one hand on the electronic device 335 ( for stability ) and use the other hand to push ( and roll ) the film 350 onto the surface of the electronic device 335 by moving the roller apparatus 300 in a downward direction 380 . as the roller apparatus 300 moves in the downward direction 380 , one or more rollers 310 and 315 press the adhesive portion 355 of the film 350 onto the electronic device 335 and squeeze out any air bubbles that may be trapped between the film 350 and the electronic device 335 . contemporaneously , the splitters 325 and 330 provide a guide for the film 350 ( i . e ., “ lead the way ”) and remove the backing portion 360 of the film 350 , thereby progressively providing more of the adhesive portion 355 of the film 350 for the rollers 310 and 315 to press down on . after the roller apparatus 300 is pulled through , across or over the length of the electronic device 335 , the adhesive portion 355 of the film 350 may be pressed onto the electronic device 335 and the user does not have to perform any other functions with respect to the surface with the applied adhesive portion 355 . depending on the design of the film 350 , this may conclude the application process . however , in certain embodiments , where the film 350 includes “ overhanging ” portions , the user may simply press these portions down onto the sides of the electronic device 335 to conclude the application process . in this manner , the user does not have to use a squeegee , wet solution , etc . to remove the air bubbles or to apply the adhesive portion 355 of the film 350 onto the electronic device 335 and the entire application process may be improved with respect to , for example , cleanliness , ease of use and convenience . fig4 a illustrates one embodiment of a roller apparatus 400 . the roller apparatus 400 may include an apparatus body 405 , a first roller 410 inserted into the apparatus body 405 and held in place by via hole 425 ( and its paired hole — not shown ). the roller apparatus 400 may also include a second roller ( not shown ) held in place by hole 430 ( and its paired hold — not shown ). the roller apparatus 400 may also include a splitter bar 415 and a mid bar 420 . the mid bar 420 may be configured to span the length of the first roller 410 and may provide structural support to the roller apparatus 400 . fig4 b illustrates how the roller apparatus 400 may be used to apply a protective material 450 onto a device 435 . the splitter bar 415 may be used to split or separate an adhesive portion of a protective material 450 from a non - adhesive backing during the application process . as shown , the roller apparatus 400 may be placed on the device 435 with the protective material 450 wedged between the first roller 410 and the electronic device 435 . as the roller apparatus 400 is moved along the surface of the electronic device 435 , the splitter bar 415 exposes the adhesive portion of the protective material 450 prior to the first roller 410 pressing the adhesive portion of the protective material 450 down onto the surface of the electronic device 435 . in addition , the non - adhesive backing is removed during this process . fig5 a illustrates one embodiment of a roller apparatus 500 . the roller apparatus 500 may include a body 505 , a first roller 520 , a second roller 515 , a splitter 510 , a first pressing surface 525 and a second pressing surface 530 . in one embodiment , the roller apparatus 500 may be constructed as one integrated piece . by integrating the first roller 520 and the second roller 515 , along with the splitter 510 into the body 505 , additional structural components may be eliminated . in one embodiment , the first roller 520 and the second roller 515 may be rod members that might not rotate . in another embodiment , the first roller 520 and the second roller 515 may be rotatable members . fig5 b illustrates how the roller apparatus 500 may be used to apply a film 550 onto a device 535 . as shown , the roller apparatus 500 may separate a top non - adhesive portion of the film 550 from the adhesive bottom portion of the film 550 as the user presses on the first pressing surface 525 and the second pressing surface 530 while moving the roller apparatus 500 along the length of the device 535 . during such an operation , the splitter 510 may separate the adhesive and non - adhesive portions of the film 550 while the rollers 520 and 515 may apply the adhesive portions of the film 550 to the surface of the device 535 . in this embodiment , the device 535 may be sandwiched or be located between the first roller 520 and the second roller 515 . the first roller 520 may contact the film 550 ( as shown in fig5 b ) on a first surface ( e . g ., a screen ) of the device 535 while the second roller 515 may contact a second surface ( e . g ., a backing ) of the device 535 . fig6 a illustrates a roller apparatus 600 , an electronic device 635 , a film 650 and an optional film tab 695 . the roller apparatus 600 may be used to apply the film 650 to a surface of the electronic device 635 . in one embodiment , the film tab 695 may be used to improve the ease of applying the film 650 as further discussed below . fig6 b illustrates one embodiment of how the roller apparatus 600 may appear when mounted on the electronic device 635 , for example , during a film application process . as shown , the roller apparatus 600 may have a width wider than the width of the electronic device 635 . in this manner , the roller apparatus 600 may be configured to apply films of varying sizes onto devices of varying sizes ( e . g ., a tablet pc ). in addition , the roller apparatus 600 may be configured to apply the film 650 to a device with a curved surface ( not shown ). however , distinct from the first operation configuration , the roller apparatus 600 may be utilized in a second operation configuration to hold , secure , prop or otherwise position the electronic device 635 such that it may be easier for a user to view and / or use the electronic device 635 . for instance , the roller apparatus 600 may be flipped over to a second operation configuration and rest on a flat surface and the like to prop up the electronic device 635 and improve viewing angles of the electronic device 635 to a user . in this manner , the roller apparatus 600 may have continued utility even after a film ( e . g ., film 650 ) is applied by the roller apparatus 600 to the electronic device 635 . as shown in fig6 c , the electronic device 635 sits in an upright manner within a cavity of the roller apparatus 600 . in one embodiment , the cavity is defined to be a space between a front bar and a first roller . fig6 d illustrates a side view of the roller apparatus 600 with the electronic device 635 held in an upright manner . as shown in fig6 d , the electronic device 635 may sit angled while still being upright . by varying the width of the cavity ( i . e ., distance between the front bar and the first roller ), the positioning of the stand edge and the like , the viewing angle may be adjusted between 90 degrees and 135 degrees . for example , as shown in fig6 d , the electronic device 635 may be held at an angle of 120 degrees as measured between a table surface and a viewing surface of the electronic device 635 . fig6 e - 6g illustrate one example of how the roller apparatus 600 may be utilized to apply the film 650 onto a surface of the electronic device 635 . as shown in fig6 e , the film tab 695 may be applied ( and may adhere ) to the film 650 and held in a preliminary application position by a user &# 39 ; s hand near the surface of the electronic device 635 . the film tab 695 may function to aid the user in lining up the film 650 with the electronic device 635 and simplifying the application process since the user may be able to handle a portion of the film tab 695 without worrying about whether the film 650 will adhere to the user &# 39 ; s fingers during the application process . the roller apparatus 600 might not be engaged at this stage . in one embodiment , the film tab 695 may be pre - installed on the film 650 for the consumer &# 39 ; s convenience . next , as shown by fig6 f , a portion of the adhesive portion 655 of the film 650 has been separated from a portion of the non - adhesive film backing 660 , and has been pressed onto the surface of the electronic device 635 . at this point of the film application process , the user may retrieve the roller apparatus 600 . the user may then utilize the roller apparatus 600 and press the adhesive portion 655 of the film 650 to the surface of the electronic device 635 with one hand while moving the roller apparatus 600 in a length - wise direction . immediately proceeding the moment when the roller apparatus 600 presses one section of the adhesive portion 655 of the film 650 onto the surface of the electronic device 635 to remove any air bubbles , the user may remove a corresponding section of the non - adhesive film backing 660 with the other hand in preparation . in this manner , the adhesive portion 655 of the film 650 may be applied to the surface of the electronic device 635 . in addition , any air bubbles between the adhesive portion 655 and the surface of the electronic device 635 resulting from the application process may be removed or squeezed out by the roller apparatus 600 being pressed and maneuvered . fig6 g illustrates an example of how the user may utilize the roller apparatus 600 to apply the film 650 to the surface of the electronic device 635 while removing any air bubbles . once the adhesive portion 655 of the film 650 is applied to the surface of the electronic device 635 , the film tab 695 may be removed by peeling ( not shown ) it from the film 650 . in this quick and efficient manner , the application process may be completed . fig7 a illustrates an embodiment of a roller apparatus 700 with an integrated stand . the roller apparatus 700 may be an embodiment of the roller apparatus 600 of fig6 . as shown , the roller apparatus 700 may be in a first operational position with rollers 710 and 715 in contact with the flat surface beneath it ( e . g ., table ). the roller apparatus 700 may include a body or carriage 705 configured to provide structural support for the rollers 710 and 715 . the carriage 705 may include attached or integrated handle portions 775 , a mid bar 720 and two contact edges 780 and 785 separated by the rollers 710 and 715 . the rollers 710 and 715 may include inner and outer cores 755 , 760 ( shown in fig7 b and 7c ), 765 and 770 ). the carriage 705 may also include a device insertion portion 795 for insertion of the electronic device ( e . g ., electronic device 635 ). however , the device insertion portion 795 may be intended for usage when the roller apparatus 700 is flipped over , as shown in fig7 b . in one embodiment , the handle portions 775 may be configured to allow a user to press down on the handle portions 775 to transfer pressure onto the rollers 710 and 715 during a protective film application process . when the user presses down on the handle portions 775 and maneuvers the roller apparatus 700 along the length of a protective film ( e . g ., film 650 ), a force may be transferred to the rollers 710 and 715 , which in turn applies a pressure to the protective film ( e . g ., film 650 ) resulting in adherence of the film ( e . g ., film 650 ) to a surface ( e . g ., a screen ) of the electronic device ( e . g ., electronic device 635 ). in addition , any air bubbles may be eliminated due to the pressure applied by the rollers 710 and 715 . the carriage 705 may be constructed out of a rigid material such as a plastic , a metal , a wood and the like . in addition , the carriage 705 may be sized to be easily graspable and manipulated by a user &# 39 ; s hand . the carriage 705 may be configured to hold the first roller 710 in place and allow the first roller 710 to “ roll ” or rotate about a longitudinal axis created by the carriage 705 . in one example , the carriage 705 may be structured to include a rod member ( not shown ) spanning the entire length of the first roller 710 , thereby forming an axis for the first roller 710 to rotate about . in another example , the carriage 705 may include two insertion portions opposite each other for inserting a rotational member of a first roller 710 . the first roller 710 may be configured to apply physical pressure on a film ( e . g ., film 650 ) in operation . the second roller 715 may be a redundant pressure applicator and may be substantially the same size as , and parallel to the first roller 710 . the first roller 710 and the second roller 715 may be separated by a mid bar 720 . the mid bar 720 may connect the two ends of the carriage 705 and provide the entire roller apparatus 700 with stability . in addition , gaps between the mid bar 720 and the rollers 710 and 715 may allow the rollers 710 and 715 to rotate freely without contacting the mid bar 720 . in one embodiment , the roller apparatus 700 may be configured to function as a film applicator for phone - sized devices and may have a length of 1 - 2 inches , a width of 2 - 4 inches , and a height of 0 . 5 - 1 inches . in one embodiment , the roller apparatus 700 may be configured to function as a film applicator for tablet - sized devices and may have a length of 1 - 5 inches , a width of 8 - 12 inches , and a height of 0 . 5 - 2 inches . other dimensions are also possible depending on the size of the device to be protected and / or the size of the film to be applied . in one embodiment , the mid bar 720 may be curved or straight , and may have a length substantially equivalent to the length of the rollers 710 and 715 , thereby joining the two ends of the carriage 705 . additionally , the mid bar 720 may be configured have a width shorter than a diameter of the outer cores 765 and 770 . in this manner , the mid bar 720 provides structural support to the roller apparatus 700 without contacting the film ( e . g ., film 750 ) or the device ( e . g ., electronic device 735 ) during the film application process . in one embodiment , the contact edge 780 may be raised and further away from the flat surface ( e . g ., the table ) than , for example , the rollers 710 and 715 when the roller apparatus 700 is positioned as shown in fig7 a . as shown in fig7 b , when the roller apparatus 700 is flipped over , the contact edge 780 raises the rollers 710 and 715 off a flat surface ( e . g ., a table ) and also orients the device insertion portion 795 such that insertion and propping of the electronic device ( e . g ., electronic device 635 ) is possible . as more clearly shown in fig7 c , when the roller apparatus 700 is in this position , the second roller 715 may be raised off the table and may allow for the electronic device ( e . g ., electronic device 635 ) to rest on an outer core 770 of the second roller 715 . more particularly , the electronic device ( e . g ., the electronic device 635 ) may be contacted on a first surface by the second roller 715 and contacted on a second surface by the stand portion 790 as it sits within the insertion portion 795 . in one embodiment , the stand portion 790 may be a flat panel having a length substantially similar to a length of the first roller 710 and the second roller 715 . as shown , the stand portion 790 may be offset from the first roller 710 and the second roller 715 . in other words , the stand portion 790 may be separated from the first roller 710 and the second roller 715 by a gap constituting the device insertion portion 795 . fig7 c is a side perspective view of the roller apparatus 700 in its second operation configuration . as shown , the rollers 710 and 715 may include the inner cores 755 and 760 , respectively . in addition , the rollers 710 and 715 may include the outer cores 765 and 770 , respectively . in one embodiment , the inner cores 755 and 760 may be constructed out of the same material ( e . g ., a rigid material such as metal , wood , and a hard plastic ). similarly , the outer cores 765 and 770 may be constructed out of the same material ( e . g ., rubber , a soft plastic , an encapsulated gel , etc .) or a softer material . in one embodiment , the material used to construct the inner cores 755 and 760 may be the same as the material used to construct the outer cores 765 and 770 . however , the densities of the material may be different . for example , the materials used to construct the outer cores 765 and 770 may be less dense and / or have a lower durometer rating . by having softer outer cores 765 and 770 , the roller apparatus 700 may be able to press the film onto the device ( e . g ., electronic device 635 ) without damaging the surface . in one embodiment , the outer cores 765 and 770 may be configured to “ flatten ” at the point of contact and thereby providing pressure in a more uniform and distributed manner , efficiently eliminating air bubbles . the outer cores 765 and 770 may be configured to return to its original configuration when not pressed to the surface of the device ( e . g ., electronic device 635 ). fig7 d and fig7 e show other various views of one embodiment of the roller apparatus 700 . fig8 a illustrates a roller apparatus 800 with an integrated stand in a first operation configuration according to another embodiment of the present invention . generally , the roller apparatus 800 may function similarly to roller apparatus 600 and 700 . more particularly , fig8 a illustrates the roller apparatus 800 in position to perform a film application process to apply a film 850 to the top surface of an electronic device 835 . as shown , the roller apparatus 800 may have a width wider than the width of the electronic device 835 . in this manner , the roller apparatus 800 may be configured to apply films of varying sizes onto devices of varying sizes ( e . g ., a tablet pc ). in addition , the roller apparatus 800 may be configured to apply the film 850 to a device with a curved surface ( not shown ). here , in preparing to apply the film 850 to the electronic device 835 , the film 850 may be placed on the surface of the electronic device 835 with a film tab 896 positioned between the film 850 and the surface of the electronic device 835 to be protected . further details of the structure of the roller apparatus 800 and the film application process are discussed below with respect to fig8 c - 8g . however , as shown in fig8 b , distinct from the first operation configuration , the roller apparatus 800 may be utilized in a second operation configuration to hold , secure , prop or otherwise position the electronic device 835 such that it may be easier for a user to view and / or use the electronic device 835 . for instance , the roller apparatus 800 may be flipped over to a second operation configuration and rest on a flat surface and the like to prop up the electronic device 835 and improve viewing angles of the electronic device 835 to a user . in this manner , the roller apparatus 800 may have continued utility even after a film ( e . g ., film 850 ) is applied by the roller apparatus 800 to the electronic device 835 . as shown in fig8 b , the electronic device 835 sits in an upright manner within a cavity of the roller apparatus 800 . in one embodiment , the cavity is defined to be a space or opening within the roller apparatus 800 . fig8 c illustrates a perspective bottom view of the roller apparatus 800 with an integrated stand . one main difference between the roller apparatus 800 and the roller apparatus 600 and 700 is that the former further includes a slit or slot 825 for receiving and guiding the film ( e . g ., film 850 shown in fig8 b ) during the film application process . as shown , the roller apparatus 800 may include a body 805 comprising a first side panel 806 , a second side panel 807 integrated with a stand portion 808 having the slit 825 . the first side panel 806 and second side panel 807 may be substantially parallel and include holes or openings to hold therebetween a first roller 815 and a second roller 820 and to allow the rollers 815 and 820 to rotate during usage to apply the film . the first roller 815 and the second roller 820 may be separated by a mid portion . the first roller 815 and the second roller 820 may be similar to the other first and second rollers described herein ( e . g ., first and second rollers 715 and 720 ). the side panels 806 and 807 may each integrate a pressing portion ( e . g ., pressing portion 876 — the other pressing portion is hidden from view ) to allow the user to press on and thereby exert pressure on the rollers 815 and 820 during the film application process . the roller apparatus 800 may also include a contact edge 890 and a non - contact edge 895 to define how the roller apparatus 800 is positioned to be operable in the second operation configuration . the contact edge 890 is operatively configured to contact a table surface and position the roller apparatus 800 to be able to receive and hold upright the electronic device 835 . as is shown , the non - contact edge 895 might not contact either the electronic device or the table surface in the second operation configuration . the operational configurations and the structure of the roller apparatus 800 having been described , attention will now be turned to the film application process . as shown in fig8 d , the user may position the film 850 having the backing still attached substantially in the position that the film 850 would be in after application . here , the film 850 may be temporarily adhered to the electronic device 835 via a film tab 896 . when positioned as shown , the user may bend the non - adhered portion of the film and move it towards the slit 825 of the roller apparatus 800 . fig8 e illustrates the film 850 as inserted through the slit 825 . as shown in fig8 f , as the film 835 is inserted through the slit 825 , the film tab 896 becomes exposed to the user . with one hand holding the roller apparatus 800 , the user may use his or her other hand to begin pulling the film tab 896 in the direction shown by arrow 855 and separate the protective layer of the film from the backing . as shown in fig8 g , as the user continues to pull the film tab 896 with one hand and exposes the protective layer of the film , the user may begin to move the roller apparatus 800 with the other hand also in the direction shown by arrow 855 to press the exposed portion of the protective layer to the electronic device 835 . in this manner , the user may progressively apply the protective layer to the electronic device 835 until the protective layer is completely separated from the backing and completely applied to the electronic device 835 . optionally , the user may use the roller apparatus 800 to further redundantly press the protective layer to ensure a thorough application . as discussed above , even after the completion of the application process , the roller apparatus 800 may still retain utility as a device stand ( e . g ., described as the second operational configuration ). any of the roller apparatus as discussed herein may be used to apply a protective film onto the surface of a mobile communication device . however , to further assist the user in applying the protective film , a roller apparatus guide 900 may be used in conjunction with a roller apparatus ( e . g ., roller apparatus 800 ). as illustrated in fig9 a , the roller apparatus guide 900 may be constructed out of materials such as polycarbonate , metal , wood ( e . g ., a cardboard or thick paper ) or any combinations thereof . the roller apparatus guide 900 may be a substantially rectangular block having three or more portions including an inner wall 905 defining a cavity 925 used to receive or mount a mobile communication device , a roller supporting surface 910 configured to be flush with a mounted mobile communication device and a set of roller guiding rails 915 which may be parallel to one another and raised above the roller supporting surface 910 . in addition , the roller apparatus guide 900 may include pressing portions 920 to assist the user when applying the protective film . as shown , the roller apparatus guide 900 may be configured to fit a particular mobile communication device with a distinct length , width and height . however , one of ordinary skill will understand that the roller apparatus guide 900 may be designed to fit any mobile communication device of any length , width and height . indeed , the cavity 925 formed by the inner wall 905 may be sized to be substantially the same as the mobile communication device to be protected . the fit of the mobile communication device within the cavity 925 may be important to ensure that the applied protective film is correctly positioned . in one embodiment , the cavity 925 formed by the inner wall 905 may be closed on a back side by a thin backing layer spanning the length and width of the cavity 925 . the thin backing layer may be integrated into the body of the apparatus guide 900 and constructed out of the same or different material . in this implementation , the cavity 925 may be formed by the inner wall 905 and the thin backing layer and the depth of the cavity 925 may be designed to maintain the feature of the mobile communication device being flush with the top surface of the apparatus guide 900 when placed into the cavity 925 . in this manner , the user may be able to use the apparatus guide 900 in various situations where a flat support surface is not readily available . in one embodiment , the roller apparatus guide 900 may include different removable and insertable portions to enable the roller apparatus guide 900 to fit multiple devices depending on which portions are inserted . for example , consider a first device having dimensions of 5 inches long by 4 inches wide by 1 inch thick and a second device having dimensions of 3 inches long by 2 inches wide by 1 inch thick . the cavity 925 of the roller apparatus guide 900 may initially be designed to fit the larger first device , but not the smaller second device . however , when a molded portion of 5 inches long by 4 inches wide by 1 inch thick having a cavity 925 that is 3 inches long by 2 inches wide by 1 inch thick is inserted in the cavity 925 of the roller apparatus guide 900 , the resulting roller apparatus guide 900 may then be utilized to fit the smaller second device . other molded portions may be swapped in and out depending on the size and shape of the mobile communication device . alternatively , the user may include further additional portions or remove inserted portions as desired to fit the particular devices . in this manner , roller apparatus guide 900 may be versatile and cater to different mobile communication devices of different sizes . the structure of the roller apparatus guide 900 having been described , attention will now be turned to the functionality as shown in fig9 b - 9h . fig9 b illustrates the roller apparatus guide 900 , a film 950 to be applied , and a mobile communication device 935 . the film 950 may be temporarily held to the roller apparatus guide 900 via an adhesive ( not shown ). as the film 950 is sized to correspond to the mobile communication device 935 ( which is to be inserted or mounted by the roller apparatus guide 900 ), the film 950 may freely move in and out of the cavity 925 as shown . fig9 c illustrates the roller apparatus guide 900 fully mounted on the mobile communication device 935 , and with the film 950 in a ready - to - be - applied position . while roller 700 is shown in fig9 c , any roller may be used in conjunction with the roller apparatus guide 900 . the roller 700 may be placed at the top of the roller apparatus guide 900 , with the film - contacting outer cores held between the roller guiding rails 915 . the distance between the roller guiding rails 915 may be configured to be the same as the length of the roller 700 thereby forming a path for the movement of the roller 700 along a surface of the mobile communication device 935 . in other words , the roller guiding rails 915 create a pathway to prevents the roller 700 from veering off the intended positional direction of application , and thus ensuring that the film 950 is applied at a correct position and providing a simplified methodology for imparting the desired precision during the film application process . as shown in fig9 d , after the user pulls a film tab 996 to expose the protective layer of the film 950 and as the user begins to move the roller 700 from one end of the mobile communication device 935 to the other end of the mobile communication device 935 in the direction of arrow 955 , the backing of the film 950 is automatically removed while the exposed protective film is applied to the mobile communication device 935 . fig9 e illustrates the roller 700 as the user is about to conclude application of the film 950 . as shown , the film backing of the film 950 is substantially separated from the applied portion of the film 950 . as shown in fig9 f , after the user finishes using the roller 700 to apply the film when the electronic device 935 is situated within the roller guide apparatus 900 , the user may remove any adhesive tabs that may have been used to attach the film 900 to the roller guide apparatus 900 for ease of positioning of the film 950 during the application process . as shown in fig9 g , the user may remove the mobile communication device 935 from the roller apparatus guide 900 by simply popping it out or lifting the roller apparatus guide 900 off the mobile communication device 935 . if desired , the user may use the roller 700 and reinforce the applied film in the manner shown in fig9 h . fig1 a illustrates a system including a roller apparatus 1075 ( which may be , for example , the roller apparatus 800 , 700 , 600 , etc . ), a roller apparatus guide 1000 ( which may be , for example , the roller apparatus 900 ), a mobile communication device 1035 , a protective film 1050 ( with a backing portion 1060 ) to be applied to a mobile communication device 1035 , and a wedge 1080 . unlike the embodiment illustrated in fig9 a - 9g , a wedge 1080 is incorporated in fig1 a to help the user apply the film 1050 to the mobile communication device 1035 . while not drawn to scale , in one embodiment , a length 1081 of the wedge 1080 may be configured to fit within a distance 1001 between rails 1002 . fig1 b illustrates the wedge 1080 apart from the previously described portions of the film application system . the wedge 1080 may be substantially triangular in shape , although minor variations are allowed provided that the functionality of the wedge 1080 remains ( as described with respect to fig1 e - 10i ). the wedge 1080 may comprise three adjacent , connected surfaces 1085 , 1090 and 1093 forming the structure of the wedge 1080 . the spacing 1095 created by the connecting of surfaces 1085 , 1090 and 1093 may be hollow or , in one embodiment , may be filled . as illustrated in fig1 c - 10d , the surfaces 1085 , 1090 and 1093 may be substantially flat and may have surface areas that are equal or different to one another ( e . g ., the surface area of the surface 1093 may be 50 % smaller than the surface area of the surface 1085 and / or 1090 ). as shown in fig1 e , the acute angle 1096 created between surfaces 1085 and 1090 may be in the range of 0 - 90 °, but preferably between 5 - 15 °. the angle 1096 is selected to allow the wedge 1080 to be manipulated by the roller 1075 during the application process . any of a plurality of materials including paper , cardboard , plastic , metal , wood , or combination thereof may be used to construct the wedge 1080 to facilitate the main functionality of the wedge 1080 . the user may initially separate the backing 1060 of the protective film 1050 by pushing the roller apparatus 1075 into the wedge . advantageously , the user does not need to manually peel the backing 1060 , and instead may rely on the wedge 1080 , thereby simplifying the process for the user . in other words , the user can simply install the protective film 1050 by moving the roller apparatus 1075 in one smooth , continuous motion . fig1 e - 10j illustrate how the wedge 1080 may be used with the roller apparatus 1075 and the roller guiding apparatus 1000 to apply the film 1050 to the mobile communication device 1035 . as illustrated in fig1 f , initially , the wedge 1080 may be positioned between the film 1050 and the mobile communication device 1035 after the mobile communication device 1035 is mounted by the roller guiding apparatus 1000 . here , the roller apparatus 1075 is placed at the top of the roller guiding apparatus 1000 . as shown , in this position , the film 1050 is separated from the surface of the mobile communication device 1035 by the wedge 1080 . in this initial position , the surface 1090 of the wedge 1080 contacts the top of the mobile communication device 1035 and / or the top of the roller guiding apparatus 1000 while the other surface 1085 of the wedge 1080 contacts the film 1050 . in addition , the surface 1085 adheres to a backing of film 1050 which assists the film application process as illustrated in the following figures . fig1 g illustrates the behavior of the wedge . as user moves the roller apparatus 1075 across the roller guiding apparatus 1000 in the direction shown by arrow 1095 , the roller apparatus 1075 places pressure on the film 1050 and / or the wedge 1080 . this in turn causes the surface 1090 to begin to move away from the top surface of the mobile communication device 1035 and / or the top of the roller guiding apparatus 1000 , while the surface 1085 continues to adhere to the backing of the film 1050 . furthermore , the configuration of the wedge 1080 and the attachment to the backing portion 1060 of the film 1050 lends itself to be flipped upwards as shown in fig1 g . as the user continues to move the roller apparatus 1075 in the direction of arrow 1095 , the backing portion 1060 of the film 1050 begins to separate from the portion of the film to be applied to the mobile communication device 1035 and at this position , the wedge 1080 is no longer in contact with the surface of the mobile communication device 1035 . instead , the wedge 1080 is separated from the top of the mobile communication device by the backing of the film 1050 as shown in fig1 h . fig1 i illustrates how the wedge 1080 works with the roller apparatus 1075 to separate the backing portion 1060 of the film 1050 and applies the exposed protective portion of the film 1050 onto the mobile communication device 1035 . as the user continues to move the roller apparatus 1075 in the direction of arrow 1095 , the pressure exerted by the roller apparatus 1075 causes the wedge 1080 to “ flip over ” such that the backing portion 1060 , which still adheres on one side to the surface 1085 of the wedge 1080 , is pulled away from the protective portion of the film 1050 . in addition , the portion of the film 1050 that remains to be separated is kept out of the way by resting on the edge between the surfaces 1090 and 1093 of the wedge . as the user manipulates the roller apparatus 1075 from the position shown in fig1 i from the end proximal to the initial position and down through the rails 1002 of the roller apparatus guide 1000 to complete the film application process , the roller apparatus 1077 continues to apply force that moves the wedge 1080 away from its initial position as shown in fig1 j . eventually , the wedge 1080 and the attached backing portion 1060 of the film 1050 may be completely separated from the protective portion of the film 1050 applied to the mobile communication device 1035 , thereby completing the film application process . in the manner described , the wedge 1080 may be utilized to assist the user to apply a film 1050 to a mobile communication device 1035 in conjunction with the roller apparatus 1075 and the roller guiding apparatus 1000 . fig1 illustrates another embodiment of a roller guiding apparatus 1100 . in this embodiment , the roller guiding apparatus 1100 may include a well for receiving any of a plurality of inserts ( e . g ., fig1 a or 12 b , described below ). each insert may be customized for a particular mobile communication device suitable for applying a protective film to that particular mobile communication device . advantageously , by configuring the roller guiding apparatus 1100 to receive any of a number of inserts , the protective film application process may be customized to any number of mobile communication devices with differing dimensions , curves , etc . while requiring only one “ universal ” roller guiding apparatus 1100 . in other words , the user may swap in and swap out different inserts depending on the particular model of a mobile communication device . the roller guiding apparatus 1100 may have a body 1160 which include interior side surfaces 1105 and an interior bottom surface 1125 , which in turn , define a well for receiving an insert apparatus ( e . g ., insert 1201 of fig1 a or insert 1202 of fig1 b ). the roller guiding apparatus 1100 may also include a pair of rails 1115 which may function similarly to the rails 915 of fig9 a . the roller guiding apparatus 1100 may further include a tab receiving portion 1185 which may be an indented area sized to fit and hold a tab of a protective film . in one or more embodiments , the tab receiving portion 1185 may include one or more side engagement members 1187 which may protrude and engage a corresponding hole in a tab . the receiving portion 1187 may also include a middle engagement member 1188 which may protrude and engage a corresponding middle hole in a tab . as shown , the roller guiding apparatus 1100 may include a base 1120 integrated at the bottom portion of the body 1160 . the base 1120 may allow a user to press down on the different portions during a film application process to stabilize the roller guiding apparatus 1100 . fig1 a illustrates one example of an insert 1201 having a ring 1250 defining a cavity 1260 for receiving a mobile communication device . fig1 b illustrates another example of another insert 1202 having a ring 1251 defining a cavity 1261 for receiving a different mobile communication device . as shown , the inserts 1201 and 1202 may have a similar or identical footprint . that is , the exterior surface of the ring 1250 and 1251 may be of the same shape and size , and configured to fit within a well of a roller guiding apparatus ( e . g ., roller guiding apparatus 1100 ). however , the interior surface of the ring 1250 and 1251 may be sized and shaped differently to fit and hold respective different models of mobile communication devices . in this manner , the user may desiring to apply a protective film to a mobile communication device a fitting the interior cavity 1260 of the ring 1250 of fig1 a may swap in the insert 1201 . and , if the user then desires to apply a protective file to a mobile communication device b fitting the interior cavity 1261 of the ring 1251 of fig1 b may remove the insert 1201 and replace it with the insert 1202 . thus , by correlating ( and designing ) each insert to fit one model of a mobile communication device , a proper fitting and film application may be performed for any of a plurality of mobile communication devices by using only one “ universal ” roller guiding apparatus when the proper insert is used . while the respective cavities shown by fig1 a and 12b extend throughout top and bottom surfaces of inserts 1201 and 1202 , in other embodiments , the bottom surface of the inserts may be closed . fig1 illustrates a film 1350 ( which may be the film 950 of fig9 d ) attached to a tab 1396 ( which may be a version of tab 996 of fig9 d ). the tab 1396 may be insertable and held in place by a roller guiding apparatus ( e . g ., roller guiding apparatus 1100 ) and may further include a pair of cylinders 1397 for engaging side engagement members of the roller guiding apparatus . the tab 1396 may also include a larger hole between placement of the holes 1397 for engaging a middle engagement member of the roller guiding apparatus . in this manner , the tab 1396 may be held in place during a film application process . as shown here , a wedge 1380 may also be used during the film application process ( e . g ., similar to the functionality of the wedge 1080 of fig1 b ). in one or more embodiments , the film 1350 having the tab 1396 may further be compatible with another roller guiding apparatus 1400 . in other words , the film 1350 may be compatible with roller guiding apparatus 1100 and / or the roller guiding apparatus 1400 . the roller guiding apparatus 1400 may differ from roller guiding apparatus 1100 in that it is configured specifically for a particular model ( i . e ., size and shape ) of a mobile communication device without requiring an insert . in one embodiment , the roller guiding apparatus 1400 is constructed out of plastic . however , other materials may be used such a metal . as shown , the roller guiding apparatus 1400 may include a body 1460 having interior side surfaces 1405 and an interior bottom surface 1425 , which in turn , define a cavity or well 1461 sized and shaped for receiving a particular model of a mobile communication device . in this manner , the user may place the mobile communication device snugly fitting the cavity or well 1461 for the purposes of applying the film ( e . g ., film 1360 ) to the mobile communication device . the depth of the cavity 1461 is about the thickness of the mobile communication device . the roller guiding apparatus 1400 may also include a pair of rails 1415 which may function similarly to the rails 915 of fig9 a . the roller guiding apparatus 1400 may include a roller guiding surface 1499 , which may include a top portion 1497 and side portions 1498 . the top portion 1497 may be a region for supporting the roller apparatus initially during the film application process . the side portions 1498 may sandwich ( e . g ., be located on either side of ) the cavity 1461 and each of the two side portions 1498 may be adjacent to a corresponding rail 1415 . the side portions 1498 of the roller guiding surface 1499 function to support the roller during a film application process by providing a support surface on the outside of the cavity 1461 and inside the rails 1415 . the top portion 1497 and the side portions 1498 lie along the same plane . the interior bottom surface 1425 lies along a plane that is substantially parallel to the plane of the top portion 1497 and the side portions 1498 . the roller guiding apparatus 1400 may further include a tab receiving portion 1485 which may be an indented area sized to fit and hold a tab of a protective film . in one or more embodiments , the tab receiving portion 1485 may include one or more side engagement members 1487 which may protrude and engage a corresponding hole in a tab . the tab receiving portion 1485 may also include a middle engagement member 1488 which may protrude and engage a corresponding middle hole in a tab . alternatively , the tab receiving portion 1485 may simply be a designated portion for attaching to a tab ( which is attached , at least in part , to the protective film ). in other words , the tab may be attached in part to the tab receiving portion 1485 and attached in part to the protective film . the tab receiving portion 1485 may function along with the tab to align the protective film for easier and more accurate alignment and application of the protective film to the screen of the electronic device . the protective film is generally a clear thin plastic material for protecting the screen of the electronic device . while not shown in fig1 , in one or more embodiments , the roller guiding apparatus 1400 may include a base integrated at the bottom portion of the body 1460 . the base may allow a user to press down on the different portions during a film application process to stabilize the roller guiding apparatus 1400 . the physical structure of certain components now having been described , attention will now be turned to how these certain components interact with each other to produce the desired effect of advantageously simplifying and making more efficient the process of applying a protective film on a mobile communication device . fig1 illustrates a roller guiding apparatus - insert apparatus system 1570 shown with an insert 1501 ( which , for example , may be insert 1201 of fig1 ) inserted into a roller guiding apparatus 1500 ( which for example , may be roller guiding apparatus 1100 of fig1 ). fig1 illustrates a roller guiding apparatus - insert apparatus system 1670 with the protective film and tab in place , awaiting the insertion of the mobile communication device to be protected by the film . more particularly , an insert 1601 ( which , for example , may be insert 1201 of fig1 ) inserted into a roller guiding apparatus 1600 ( which for example , may be roller guiding apparatus 1100 of fig1 ), and a protective film 1650 having a tab 1696 is placed in position . in practice , mobile communication device designed to snugly fit within the insert 1601 may be inserted into the cavity of the insert prior to the placement of the protective film 1650 and the tab 1696 being placed in position . however , the mobile communication device in this instance has been removed for clarity . as is shown in fig1 , the roller guiding apparatus 1600 may include rails 1615 for guiding a roller used in the film application process . the roller guiding apparatus 1600 may also include a base 1620 for allowing a user to better grip and manipulate the roller guiding apparatus 1600 during a film application process . the interaction between the tab receiving portion 1686 and the tab portion 1696 is also illustrated in fig1 . here , the tab 1696 may held in position by the tab receiving portion by substantially lining up the tab 1696 into the indent at the tab portion 1696 . alternatively or in addition , a pair of side engagement members 1687 of the tab receiving portion 1686 and a middle engagement member 1688 may penetrate corresponding holes 1697 and 1698 for holding the tab portion 1696 in place and for accurately aligning the tab portion 1696 so that the protective film 1650 can be properly and accurately applied onto the mobile communication device . once the mobile communication device is inserted in place , operation to apply the protective film 1650 may be similar to operations described herein ( e . g ., as shown in fig9 b - 9f ). fig1 illustrates a roller guiding apparatus system 1770 with the protective film and tab in place , awaiting the insertion of the mobile communication device to be protected by the film . that is , instead of operating with roller guiding apparatus 1670 , the film 1650 may be used in connection with the roller guiding apparatus system 1770 . the protective film 1650 having a tab portion 1696 is placed in position as shown in fig1 . in practice , mobile communication device designed to fit within the roller guiding apparatus system 1770 may be inserted into the cavity of the prior to the placement of the protective film 1650 and the tab portion 1696 being placed in position . however , the mobile communication device in this instance has been removed for clarity . as is shown in fig1 , the roller guiding apparatus system 1770 may be constructed out of a flexible , semi - rigid or rigid plastic material for use in the film application process . the interaction between the tab receiving portion 1786 and the tab portion 1696 is also illustrated in fig1 . here , the tab 1696 may be held in position by the tab receiving portion 1786 by substantially lining up the tab 1696 into the indent at the tab receiving portion 1786 . alternatively or in addition , a pair of side engagement members 1796 and 1797 of the tab receiving portion 1786 may penetrate corresponding holes 1686 and 1687 , and a middle engagement member 1798 may penetrate corresponding middle hole 1688 for holding the tab portion 1696 in place and for accurately aligning the tab portion 1696 so that the protective film 1650 can be properly and accurately applied onto the mobile communication device . once the mobile communication device is inserted in place , operation to apply the protective film 1650 may be similar to operations described herein ( e . g ., as shown in fig9 b - 9f ). fig1 a illustrates one embodiment of a roller apparatus 1800 . the roller apparatus 1800 may be , for example , a variant of roller apparatus 200 , 300 , 400 and may be structured to accomplish substantially the same functions . one difference between the roller apparatus 1800 and other roller apparatuses whether disclosed herein or not , is that the roller apparatus 1800 may include the finger supporting platform 1825 having the plurality of indentations 1826 , 1827 and 1828 . the finger supporting platform 1825 is substantially flat except for the areas of the plurality of indentations 1826 , 1827 and 1828 . as shown , the roller apparatus 1800 may further include a roller base or carriage 1805 , a first or front roller 1810 , a second or back roller 1815 and a mid - bar 1820 . the roller base 1805 may be constructed out of a rigid material such as a plastic , a metal , a wood and the like . the roller base 1805 is configured to provide structural support for the roller apparatus 1800 . in addition , the roller base 1805 may be sized to be easily manipulated and by the user placing one of his or her fingers in each of the plurality of indentations 1826 , 1827 and 1828 . the roller base 1805 may be configured to hold the first roller 1810 in place and allow the first roller 1810 to “ roll ” or rotate about a longitudinal axis created by the roller base 1805 . in one example , the roller base 1805 may be structured to include a first rod member ( not shown ) spanning the entire length of the first roller 1810 , thereby forming an axis or axle for the first roller 1810 to rotate about . the first roller 1810 is configured to rotate and apply physical pressure on a film ( e . g ., film 150 of fig1 ) in operation . the second roller 1815 may be an additional pressure applicator and may be substantially the same size as , and substantially parallel to the first roller 1810 . the roller apparatus 1800 may include a second rod member ( not shown ) spanning the entire length of the second roller 1815 , thereby forming an axis or axle for the second roller 1815 to rotate about . the first roller 1810 and the second roller 1815 may be separated by a mid bar 1820 . the mid bar 1820 may connect the two ends of the roller base 1805 and provide the entire roller apparatus 1800 with stability . fig1 b is a perspective view of the roller apparatus 1800 . in one embodiment , the roller apparatus 1800 may be configured to function as a film applicator for phone - sized devices and may have a length of 1 - 2 inches , a width of 2 - 4 inches , and a height of 0 . 5 - 1 inch . in one embodiment , the roller apparatus 1800 may be configured to function as a film applicator for tablet - sized devices and may have a length of 1 - 5 inches , a width of 8 - 12 inches , and a height of 0 . 5 - 2 inches . other dimensions are also possible depending on the size of the device to be protected and / or depending on the size of the film to be applied . as shown , each of the plurality of indentations 1826 , 1827 and 1828 has a curved concave surface for easy manipulation by the user &# 39 ; s fingers and for allowing stronger pressure to be applied for proper application ( i . e ., little to no air bubbles between the protective film and the electronic communication device ) of the protective film . fig1 a is a perspective view of a system 1900 , which may include the roller apparatus 1800 of fig1 a , the roller guide apparatus 1400 of fig1 , the wedge 1380 ( e . g ., a triangular shaped wedge ) of fig1 b , and the protective film 1650 of fig1 . the roller guide apparatus 1400 is substantially rectangular in shape ( e . g ., with rounded edges ) and the cavity 1461 is substantially rectangular in shape ( e . g ., with rounded edges ) or shaped to allow the electronic device 135 to fit snugly therein . as shown , the electronic device 135 of fig1 in inserted into the cavity 1461 of the roller guide apparatus 1400 such that the top surface or screen of the electronic device 135 is flush with ( i . e ., lies along the same or substantially the same plane ) or is slightly above the side portions or surfaces 1498 of the roller supporting surface 1499 of the roller guide apparatus 1400 . as shown , the roller apparatus 1800 is positioned between the rails 1415 at the top portion 1497 of the roller guide apparatus 1400 . the rails 1415 protrude or extend above the roller supporting surface 1499 . the rails 1415 are used to contain or guide the roller apparatus 1800 therebetween for moving the roller apparatus 1800 along or on the roller supporting surface 1499 . the wedge 1380 is attached to a backing of the protective film 1650 . the wedge 1380 is used to help pull the backing off the protective film 1650 when the roller apparatus 1400 is pushed against the tab 1696 and / or the protective film 1650 . once the backing of the protective film 1650 is partially or fully separated from the adhesive portion , the roller apparatus 1400 may be moved in the direction of the arrows to perform both the application of the protective film 1650 and the removal of the backing of the protective film 1650 . furthermore , the rails 1415 are substantially parallel and serve to align and guide the movement of the roller apparatus 1400 , thus the system 1900 may be considered to be self - aligning and air bubble - free . fig1 b is a top view of the system 1900 of fig1 a and more clearly illustrates the top portion of the roller supporting surface 1499 on which the roller apparatus 1800 is shown positioned . the side portions 1498 of the roller supporting surface 1499 are shown on both sides of the electronic device 135 and function as portions of the roller guide apparatus 1400 which support the roller apparatus 1800 during the film application process . in one or more embodiments , the rails 1415 of the roller guide apparatus 1400 may be removed or eliminated to allow the user variations in control of the movement of the roller apparatus 1800 . fig2 a illustrates another embodiment of a roller apparatus 2000 which may be used to apply a protective film to a surface of a mobile communication device . here , the roller apparatus 2000 may include a roller 2005 attached to a body 2010 . the body 2010 may include a head 2015 , a curved neck 2025 and a shaft 2030 configured to be gripped by a user &# 39 ; s hand for operation of the roller apparatus 2000 . the head 2015 may be attached to the roller 2005 via connectors 2020 which enable the roller 2005 to spin about an axis in a manner similar to the other rollers described herein to apply a pressure to a protective film ( e . g ., film 1650 ) during a film application process . fig2 b and 20c illustrate a side view and a front view of the roller apparatus 2000 . the roller 2000 may be used as a stand alone device or as part of a system including a roller supporting apparatus ( e . g ., in place of roller 1800 as part of the system 1900 ). fig2 illustrates a system 2100 , which may include the roller guide apparatus 1400 of fig1 , the wedge 1380 of fig1 b , and the protective film 1650 and tab 1696 of fig1 . the system may also include a flange 2102 and an adhesive film 2104 , and may include a roller apparatus , for example the roller apparatus 1800 of fig1 a ( not shown ). the flange 2102 is configured to couple to the protective film 1650 to provide support for the film 1650 . the flange 2102 extends outward from the film 1650 when coupled thereto . in one embodiment , the flange 2102 may comprise a rigid structure , having a rigidity that is greater than the protective film 1650 . the rigidity of the flange 2102 may provide added strength to the protective film 1650 when the protective film 1650 is applied to a surface of a mobile communication device , for example the mobile communication device 135 of fig1 . the flange 2102 may also be shaped to apply a shape to the protective film 1650 when the flange 2102 is coupled to the protective film 1650 . the flange 2102 shown in fig2 , for example , has a curved shape ( more clearly shown in fig2 d ). the shape of the flange 2102 may deflect a portion of the protective film 1650 away from the mobile communication device that is positioned within the cavity 1461 . the protective film 1650 may more easily apply to a surface of the mobile communication device if the protective film 1650 is deflected away from the surface of the mobile communication device , prior to , or while being applied . the flange 2102 may have any shape that allows it to provide support for the film 1650 . for example , the flange 2102 shown in fig2 is u - shaped , as it has two parallel lengths connected by a transverse connecting length . when the flange 2102 shown in fig2 is coupled to the protective film 1650 , the protective film 1650 is bounded by the lengths of the u - shaped flange 2102 . the flange 2102 may be sized to fit between the rails 1415 of the roller guide apparatus 1400 . the flange 2102 may be sized to abut each of the rails 1415 when the protective film 1650 is applied to the surface of the mobile communication device . the abutment of the flange 2102 to the rails 1415 may serve to reduce movement of the protective film 1650 towards at least one of the rails 1415 when the protective film 1650 is applied to the surface of the mobile communication device . the protective film 1650 may accordingly be more accurately aligned and applied to the surface of the mobile communication device . the adhesive film 2104 may be configured to couple the flange 2102 to the protective film 1650 . the adhesive film 2104 may also join the protective film 1650 to the tab 1696 . the adhesive film 2104 may include adhesive that bonds to the flange 2102 and the protective film 1650 . a portion or the entirety of the adhesive film 2104 may include adhesive that bonds with any of the flange 2102 , protective film 1650 , or tab 1696 . in one embodiment , the adhesive film 2104 may extend outward from the protective film 1650 . for example , in the embodiment shown in fig2 , the adhesive film 2104 is configured to extend outward from the protective film 1650 to join with the flange 2102 . the flange 2102 couples to the protective film 1650 with the adhesive film 2104 . the adhesive film 2104 may be configured to be as rigid or flexible as the protective film 1650 . in one embodiment , the adhesive film 2104 may be less rigid than the flange 2102 . in one embodiment , the adhesive film 2104 may be as rigid as the flange 2102 . the components of the system 2100 may be provided as components that are coupled together , or may be provided as components to be coupled together by an individual . for example , the system 2100 may be provided as a kit that is assembled by an end - user . fig2 a illustrates the protective film 1650 coupled to the wedge 1380 . the wedge 1380 is preferably positioned beneath the protective film 1650 . the wedge 1380 may be adhered to the protective film 1650 at an end of the protective film 1650 , through any suitable method or means discussed in this application . fig2 b illustrates the adhesive film 2104 coupled to the protective film 1650 . the adhesive film 2104 is preferably positioned on top of the protective film 1650 . the adhesive film 2104 extends outward from the protective film 1650 . the adhesive film 1650 also couples the protective film 1650 to the tab 1696 . the adhesive film 1650 includes adhesive portions 2201 that include an adhesive , such as a glue , that is used to couple the flange 2102 to the protective film 1650 . any other form of adhesive or other coupling method or means discussed in this application may be used by the adhesive film 2014 to couple the flange 2102 to the protective film 1650 . fig2 c illustrates the flange 2102 coupled to the protective film 1650 . the flange 2102 couples with the adhesive portions of the adhesive film 2104 that extend outward from the protective film 1650 to couple to the protective film 1650 . the flange 2102 is preferably positioned on top of the adhesive film 2104 . as such , in the embodiment shown in fig2 c , the flange 2102 surrounds the protective film 1650 without covering the protective film 1650 . fig2 d illustrates a curvature of the flange 2102 . the curvature is represented by the arrows 2202 . the flange 2102 is curved from one end to the other such that the flange 2102 curves in a direction away from the cavity 1461 when the flange 2102 is coupled to the protective film 2104 and the protective film 2104 is coupled to the roller guide apparatus 1400 . the flange 2102 may have a uniform curve or may be variably curved or non - curved at portions of the flange 2102 . fig2 e illustrates a side perspective view of the flange 2102 coupled to the protective film 1650 . the curvature of the flange 2102 applies a curvature to the protective film 1650 represented by arrows 2204 . the curvature of the protective film 1650 may substantially match the curvature of the flange 2102 . fig2 f illustrates a top view of the flange 2102 and the protective film 1650 coupled to the roller guide apparatus 1400 . in this embodiment , the rails 1415 of the apparatus 1400 are separated from one another at a distance 2206 . the flange 2102 is sized to form a width 2208 that extends the distance 2206 of the rails 1415 , such that the flange 2102 fits between the rails 1415 . the width 2208 may be substantially identical to the distance 2206 such that the flange 2102 closely fits between the rails 1415 with a small amount , or no space therebetween . the flange 2102 may be sized in this manner such that the flange 2102 abuts each of the rails 1415 when the protective film 1650 is applied to the mobile communication device . the flange 2102 may contact the rails 1415 to reduce movement of the protective film 1650 transverse to the direction the film 1650 is applied , so that the film 1650 aligns and applies accurately to the surface of the mobile communication device . if a roller apparatus is used to apply the film 1650 , the flange 2102 may prevent the protective film 1650 from shifting transverse to the direction the roller apparatus is rolled , which may be caused be a user applying a transverse force to the protective film 1650 with the roller apparatus . the configuration of the flange 2102 , the protective film 1650 , the adhesive film 2104 , and the roller guide apparatus 1400 shown in fig2 f may be provided to an end - user , or an end - user may assemble the components 2102 , 1650 , 2104 , 1400 into the configuration shown in fig2 f . each of the components 2102 , 1650 , 2104 , 1400 may be configured to couple to each other prior to the end - user coupling the components to each other . each of the components 2102 , 1650 , 2104 , 1400 may be configured to removably couple to each other such that an end user may separate the components after use . fig2 a illustrates a side perspective view of the flange 2102 and the protective film 1650 coupled to the roller guide apparatus 1400 . the flange 2102 has a curvature represented by the arrows 2302 and applies this curvature to the protective film 1650 to deflect the protective film 1650 away from the surface of the mobile communication device 135 . an end of the protective film 1650 that is positioned closer to the tab 1696 is positioned closer to the surface of the mobile communication device 135 than the opposing end of the protective film 1650 . the deflection of the protective film 1650 away from the mobile communication device 135 serves to allow a backing portion of the protective film 1650 to more easily separate from an application portion of the protective film 1650 . the deflection of the protective film 1650 may create space for the backing portion to pass away from the application portion in a direction away from the tab 1696 . in addition , in an embodiment in which the wedge 1308 is utilized , the wedge 1308 may more easily pass in a direction away from the tab 1696 if the opposing end of the protective film 1650 is elevated . fig2 b illustrates the embodiment shown in fig2 a after the backing portion 1660 has been partially separated from the application portion 1655 . the wedge 1308 has passed in a direction away from the tab 1696 . the application portion 1655 is applied to the surface of the mobile communications device 135 . the flange 2102 abuts each of the rails 1415 when the application portion 1655 is applied to the surface of the mobile communications device 135 . the flange 2102 abuts an interior surface of each of the rails 1415 that faces towards the other rail 1415 . the interior surface contacts the flange 2102 to prevent or reduce the opportunity for the application portion 1655 to slide side to side and be improperly aligned on the surface of the mobile communications device 135 . the flange 2102 may be lowered while the application portion 1655 is applied , from the height shown in fig2 a to the height shown in fig2 b . the lowering of the flange 2102 may be caused by the wedge 1308 being drawn out from beneath the protective film 1650 , and / or by the protective film 1650 being pressed downward during the application process . a roller apparatus may be used to apply the protective film 1650 in the embodiment shown in fig2 a and 23b . the flange 2102 remains coupled to the application portion 1655 while the backing portion 1660 is separated from the flange 2102 . the flange 2102 may be removed from the application portion 1655 at a later time . fig2 a illustrates an embodiment in which the flange 2402 is coupled to the protective film 1650 without use of an adhesive film . the flange 2402 in this embodiment may be directly adhered to the protective film 1650 through use of a suitable adhesive or any other suitable method or means disclosed in this application . a separate film 2497 may couple the protective film 1650 to the tab 1696 . the flange 2402 in this embodiment may comprise two separate pieces that extend outward from the protective film 1650 . the two pieces of the flange 2402 may combine to form a width 2404 that extends the distance 2206 of the rails 1415 , such that the flange 2402 fits between the rails 1415 . the width 2404 may be substantially identical to the distance 2206 such that the flange 2402 closely fits between the rails 1415 with a small amount , to no space therebetween , in an manner similar to the embodiment shown in fig2 f . the flange 2402 may similarly be sized such that the flange 2402 abuts each of the rails 1415 when the protective film 1650 is applied to the mobile communications device . the flange 2402 in this embodiment may not have a curve , or other deflected shape . the flange 2402 may comprise substantially straightened material . fig2 b illustrates a side perspective view of the embodiment shown in fig2 a . the flange 2402 in this embodiment does not apply a curvature to the protective film 1650 . in one embodiment , the flange 2402 may be sized to extend out further than the distance 2206 between the rails 1415 . in one embodiment , the flange 2402 may not abut the rails 1415 , but may provide rigidity and stability to the protective film 1650 during application to the mobile communication device by comprising a flanged structure extending from the protective film 1650 . any of the components discussed in fig2 - 24b may be utilized or interchanged with any other component discussed in this application to produce a desired result . skilled artisans may implement the described
