referring to the drawings fig1 , is a simplified block diagram of inductive charging electronics for a docking system . the use of an inductive charging circuit in a docking station provides improvement over docking stations that require that the mobile electronic device be plugged in to a connector or cable that provides charging . inductive charging is an improved method of charging that does not require electrical conducting connectors between the base 10 and the sleeve 9 . referring more particularly to fig1 , ac power 1 may be used provide a source of power for a docking system , ac power 1 may range for example from 90 v ac to 240 v ac at 50 hz to 60 hz depending on where you are located in the world , other ac power voltages and frequencies may also be used . the external power supply 2 receives input ac power for example of 90 v ac to 240 v ac at 50 hz to 60 hz from ac power 1 . the external power supply can be a wall mounted unit that is plugged directly in to an ac power 1 outlet and may use country specific plug adapters to mate with the style of ac power 1 outlet . a power source such as an external power supply 2 provides input power for the driver board 3 of the docking system base 10 . a dc power input from a battery system in a vehicle such as an automobile could also be used in place of the ac power and external power supply to provide input to the driver board 3 . the driver board 3 is used to drive electrical current in to the driver coil 4 at a frequency range for example of 60 khz to 130 khz , other frequencies may be used . the

copper clad printed circuit board material . the receiver coil 5 may alternately be fabricated using multilayer printed circuit board material allowing the turns of the receiver coil 5 represented in etched copper be placed in series therefore increasing the turns of the receiver coil 5 and increasing the receiver coil 5 ac voltage level that is determined by the ratio of the receiver coil 5 windings to driver coil 4 windings or in parallel reducing the resistance of the receiver coil 5 therefore increasing the receiver coil 5 current carrying capability and reducing the receiver coil 5 heat caused by the current flow during charging the mobile electronic device 7 resulting in a voltage drop caused by resistance of the receiver coil 5 . a flat piece of ferrite material may be placed on the side of the receiver coil 5 printed circuit board that is most distant from the driver coil 4 when the sleeve 9 is docked on a base 10 . a flat ferrite piece on the back of the receiver coil 5

be used in parallel with the receiver coil 5 to for near to resonance operation of the receive circuit . at resonance the transfer function of energy to the receive coil may approach 1 and therefore increase the efficiency of the inductive charging circuit allowing the circuit to deliver the higher charging currents required by mobile electronic devices such as the ipad . the ac input from a receiver coil 5 may be rectified in to unregulated dc voltage by a full wave bridge on a main board 6 . the unregulated dc voltage from the bridge rectifier may be used as the input for a dc to dc switching power regulator circuit on the main board 6 . the use of a switching power regulator on a main board 6 may improve the efficiency for example from 20 % to nearly 90 % of the conversion of unregulated dc voltage input to regulated voltage output over the use of conventional linear voltage regulators . the switching power regulator may be configured to output regulated + 5 vdc output or other voltage for charging a mobile electronic device 7 . the output of a main board &# 39 ; s 6 regulated dc output is used as the input to a connector board 8 . the connector board 8 may be located

bridge is not needed to create dc voltage . the dc voltage from the full or half wave bridge rectifier or dc power input from the receiver contacts 55 may be used as the input for a dc to dc switching power regulator circuit on the regulator board 56 . the use of a switching power regulator on the regulator board 56 may improve the efficiency from 20 % to nearly 90 % of the conversion of unregulated dc voltage input to regulated voltage output over the use of conventional linear voltage regulators . the switching power regulator may be configured to output regulated + 5 vdc output or other voltage for charging a mobile electronic device 7 . the output of a regulator board &# 39 ; s 56 regulated dc output is used as the input to a connector board 57 . the connector board 57 may be located in the sleeve 38 and may include a mating connector for the charging port on the mobile electronic device 7 . the connector board 57 may also include a connector that is accessible from the outside of the sleeve 38 that allows an alternate method to charge the mobile electronic device 7 using a conventional charger . the mobile electronic device 7 charging port may plug in to a mating connector 27 on the connector board 57 when a mobile electronic device 7 inserted in to the sleeve 38 . the sleeve 38 may be intended to remain in place on the mobile electronic device 7 semi - permanently and does not need to be removed for normal use of the mobile electronic device 7 . the sleeve 38 may be form fitting and also may provide a level of increased protection for the mobile electronic device 7 . the mobile electronic device 7 installed in the sleeve 38 may be placed on the base 45 to charge the mobile electronic device 7 . optionally , no additional plugging of cables or connectors are required to charge the mobile electronic device 7 when installed in the sleeve 38 and placed on the base 45 that is receiving power from an external power supply 2 . the driver contacts 54 of the base 45 may need to be aligned properly with the receiver contacts 55 in the sleeve 38 to properly transfer power and allow charging of the mobile electronic device 7 . smaller magnets 35 in the sleeve 38 may be used to attract to ferrous metal in the base 45 . a combination of magnetic force and mechanical design features of a base 45 and a sleeve 38 may be used to enable the sleeve 38 to be easily docked properly aligning the receiver contacts 55 and the driver contacts 54 on the base 45 without excessive care from the intended user . the mechanical design features of the base 45 and the sleeve 38 also allow the sleeve 38 to be rotated to any position on axis within a single plane while a sleeve 38 is installed on the base 45 . the magnetic force may be used to hold the base 45 and sleeve 38 together with enough force to allow the mobile electronic device 7 to be used normally while docked . the magnetic force between the sleeve 38 and base 45 may be such that it is not strong enough to prevent the mobile device 7 held in the sleeve 38 from easily being undocked by a user and used as a mobile electronic device 7 . referring to fig1 , fig1 is a simplified flow chart of the operation of the docking system microcontroller firmware . the microcontroller is initialized when the docking system has power applied from the external power supply . this is the power on state of the docking system . the microcontroller next initializes the internal registers that control the input and output pin configurations and timers that may be used . after initialization is complete the system enters low power mode . in low power mode the charging function is disabled or off . the docking system may stay low power mode and loop checking if a sleeve has been docked . when the docking system detects that a sleeve has been docked it will exit low power mode and enter charge mode . the charging function is enabled or turned on in charge mode . the firmware will remain in char mode and loop checking that a sleeve is still docked . if the sleeve remains docked on the docking system then charge mode will remain on . if the sleeve is removed from the dock the docking system will return to low power mode and the charge function will be turned off . the docking system will remain in low power mode until a sleeve is docked and the process describe above will repeat indefinitely until power to the docking system is removed . certain systems and methods disclosed herein can be implemented in hardware , software , firmware , or a combination thereof . software can
