referring now to the drawings , and more particularly to fig1 , there is shown an embodiment of a confinement system 10 , which utilizes an embodiment of a method of the present invention of rising stimulation . confinement system 10 is illustrated with an animal 12 wearing a receiver collar 14 that uses information it receives to confine animal 12 within inner - boundary 16 . receiver collar 14 , also known as a stimulation device 14 , utilizes the information to determine if animal 12 should receive one or more stimulations from receiver collar 14 . inner - boundary 16 and outer - boundary 18 are used to define enforcement zone 20 therebetween . when animal 12 crosses inner - boundary 16 , stimulation device 14 is activated , providing a stimulus to animal 12 , thereby providing an incentive for animal 12 to not cross into or through enforcement zone 20 and to stay within inner - boundary 16 . now , additionally referring to fig2 and 3 , when animal 12 crosses inner - boundary 16 an initial stimulation is applied by stimulation device 14 . as long as animal 12 stays within enforcement zone 20 , the stimulation level is increased as shown in time periods 1 - 7 . the rise in stimulation occurs over a relatively short period of time during which an evaluation is ongoing to determine whether animal 12 is still in enforcement zone 20 . when animal 12 retreats within inner - boundary 16 , the applied stimulation is terminated as shown in time periods 8 - 11 in fig2 . if animal 12 enters enforcement zone 20 at some later period of time , for example , at time periods 12 , 13 , 17 , 21 and 22 as illustrated in fig2 , then a stimulation is applied during these time periods . the stimulation level utilized , in this example , to enforce compliance with animal 12 , during time period 12 is one increment less than the maximum applied in the previous stimulation , time period 7 . at time period 12 non - compliance is again detected and the current stimulation level is applied , since the response was not immediate the stimulation level at time period 13 is elevated . in a like manner at time period 17 , stimulation is applied at level 6 , which is one incremental level lower than the previous applied stimulation at time period 13 . since animal 12 responded immediately at time period 17 , no additional stimulations were applied during time period 18 . then in accordance with the present invention , the stimulation level is lowered to level 5 as illustrated in fig3 . at time period 21 , animal 12 again violates enforcement zone 20 and stimulation is applied at level 5 , corresponding to the stimulation level as shown in fig3 . again , animal 12 delays compliance until a second time period and the applied stimulation is increased by one level at time period 22 . although , the embodiment discussed above is directed to a confinement system , the modification of other types of behavior , such as barking , are also subject to modification by the present invention . advantageously , the present invention adjusts the stimulation level to be responsive to the sensitivity of animal 12 . as long as animal 12 quickly responds to the stimulation , the stimulation level is adjusted accordingly . if animal 12 should go beyond outer - boundary 18 , receiver collar 14 is deactivated until animal 12 is again within inner - boundary 16 . this eliminates punishment to animal 12 when animal 12 is beyond outer - boundary 18 and when animal 12 re - enters the desired area defined by inner - boundary 16 . now , additionally referring to fig4 , there is illustrated a continuous stimulation level increase , thereby indicating that the stimulation level may vary in an analog fashion rather than in a digital fashion as illustrated in fig2 and 3 . now , additionally referring to fig5 , there is shown an embodiment of the present method of rising stimulation 100 in block diagram form . upon initiation of method 100 , the current stimulation level is set to a minimum value at step 102 . the current stimulation level can be reset to an initial minimum value at step 102 by a triggering event , such as when a battery in receiving collar 14 is replaced , when the battery is recharged or by a manual reset by way of a mechanical or magnetically activated switch in collar 14 . at step 104 , method 100 determines whether animal 12 is compliant . compliance is determined by either the non - detection of a violation of a set boundary , such as inner - boundary 16 as illustrated in fig1 , in another automatic manner or by observation of a trainer . if the animal is not compliant , method 100 proceeds to step 106 , otherwise method 100 returns to step 104 . if at step 104 it was determined that the animal is not compliant , then stimulation is applied at step 106 . the stimulation that is applied is based upon the current stimulation level as illustrated in fig3 . the stimulation may be at a minimum level if animal 12 has become non - compliant for the first time since the initiation of the system or if the stimulation level is lowered by action of method 100 . the stimulation level is set one level less than that utilized to obtain conformance in the prior non - conformal act of animal 12 . the applied stimulation may be applied in packets such as in fig2 where the applied stimulation is turned on and then off , then if animal 12 remains non - compliant the stimulation is turned back on at level 2 and so forth as it stair - steps up to a level at which animal 12 becomes compliant , such as level 7 , in this example . alternatively , the applied stimulation is applied continuously during non - compliant behavior . at step 108 , animal 12 is again checked for compliance . if animal 12 is not compliant , method 100 proceeds to step 110 where the current stimulation level is increased as illustrated in fig2 , 3 and / or 4 . with the stimulation level increased , method 100 returns to step 106 where the stimulation is again applied to animal 12 , but at the increased stimulation level . if , at step 108 animal 12 is now determined to be compliant , then method 100 proceeds to step 112 . at step 112 , method 100 lowers the stimulation level by an increment as illustrated at time period 8 of fig3 . the stimulation level is lowered only one increment in order to receive more immediate response from animal 12 in the event of a repeated non - compliant behavior . by reducing the stimulation level by one increment , it is likely that animal 12 will respond more quickly to this initial level of stimulation , thereby obviating the need to apply ineffective stimulation over several time periods . once the stimulation level is lowered by an increment at step 112 , method 100 returns to step 104 . alternatively , the stimulation levels may be decreased by more than one step , but not immediately to the minimal level , thereby preserving an effective stimulation level for a more immediate response from animal 12 . this approach advantageously reduces power consumption by the receiver collar 14 by obtaining quicker response from animal 12 to the stimulation . while this invention has been described as having a preferred design , the present invention can be further modified within the spirit and scope of this disclosure . this application is therefore intended to cover any variations , uses , or adaptations of the invention using its general principles . further , this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims .
