  • the housing 102 carries a movable button control element 106 with a depressible member 108 that is positioned over the button 104.
  • the remote control 100 will generate a signal when the button 104 is pressed and, depending on its position, the button control element 106 will control the operation of the button by either preventing or allowing the button to be pressed.
  • the exemplary remote control 100 is shown in the locked state, i.e. the state in which the button 104 may not be pressed, in Figures 1 and 2. More specifically, when the movable button control element 106 is in the position illustrated in Figures 1 and 2, the depressible member 108 will be aligned with a barrier 110 ( Figure 3) on the housing 102.
  • the barrier 110 which may include abutments 112, prevents the depressible member 108 on the button control element 106 from being depressed, thereby preventing the button 104 from being pressed.
  • the exemplary remote control 100 may be adjusted to the unlocked state illustrated in Figures 3 and 4, i.e. the state in which the button 104 may be pressed, by moving the button control element 106 in the direction of arrow A until the depressible member 108 is no longer aligned with the barrier 110 and is instead aligned with a housing aperture 114 that is adjacent to the barrier.
  • the housing 102 in the exemplary embodiment includes a surface 116 that is shaped to receive the user's forefinger and the button control element 106 includes a raised area 118 that combines with the depressible member 108 to form a region that is shaped to receive the user's thumb.

  • the depressible member 108 and raised area 118 also include ridges 120 which prevent the user's thumb from slipping.
  • the housing 102 and button control element 106 perform the advantageous function of preventing inadvertent communication between the exemplary remote control 100 and the associated medical device by preventing the button 104 from being pressed unless the user has demonstrated his/her intent to press the button. Such intent is demonstrated, in the context of the exemplary remote control 100, by sliding the button control element 106 from the locked position ( Figures 1 and 2) to the unlocked position ( Figures 3 and 4) prior to pressing the button 104.

  • the depressible member 108 when the remote control 100 is in the unlocked state ( Figures 3-5). Specifically, the depressible member 108 will press the resilient cover 148 which, in turn, will press the movable element 144 of the actuator 142 and close the switch. In some alternative embodiments, the housing aperture 114 will be uncovered and the depressible member 108 will come into direct contact with the actuator 142. In either case, the controller 138 will instruct the communication device 140 to transmit a signal when the switch is closed. Additional information concerning functionality of the controller 138 as well as the other elements carried by the circuit board 134 is provided below in the context of Figures 41 and 42.
  • the top member 124 of the exemplary housing 102 covers the bottom member 122, thereby defining a closed interior space, and also includes the housing aperture 114.

  • the top member 124 illustrated in Figures 6-8 has a main wall 156 that forms the first and second sections 150 and 152, an outer wall 158, and inner walls 160 and 162.
  • the outer and inner walls 128-132 of the bottom member 122 abut the outer and inner walls 158-162 of the top member 124.
  • the bottom member 122 may also be provided with a plurality of holes (not shown), and the top member 124 may also be provided with a corresponding plurality of posts (not shown) that are configured to be interference fit into the holes to secure the top member to the bottom member.
  • the button control element includes a main wall 164 and an outer wall 166.
  • the button control element 106 is also configured to slide along the second section 152 of the housing top member 124. To that end, the button control element 106 is provided with a pair of longitudinally extending inner walls 168 that are in close proximity to, as well as parallel to, the two longitudinally extending portions of the top member inner wall 160. The button control element 106 also has transversely extending inner walls 170 that are positioned such that they abut transversely ending walls 172
  • the button control element 106 also includes covers 174 ( Figure 8) that extend inwardly from the outer wall 166.

  • the button control element 106 includes a plurality of stop members 181 that engage the curved portion of the inner wall
  • the longitudinally extending portions of the top member inner wall 160, the movable portion inner walls 168, the covers 174, the top member wide portions 176, the guides 178 and slots 180 individually and collectively prevent the movable button control element 106 from sliding in any direction other than along the longitudinal axis of the housing 102.
  • the orientation of the longitudinal axis is the same as the orientation of arrow A in Figure 3.
  • the guides 178 also prevent debris from entering the housing 102 when the button control element 106 is in the unlocked position.
  • the covers 174 and the top member wide portion 176 also prevent the button control element 106 from being moved upwardly (in the orientation illustrated in Figure 7) and pulled off the housing top member 124. Similarly, the alignment of the housing first section 150 with the button control element 106 (including the depressible member 108) prevents a fingernail or object from getting under, and lifting, the depressible member when the remote control 100 is in the locked state.
  • the button control element 106 is biased to the locked position illustrated in Figures 1 , 2, 7 and 8. Thus, unless the user is applying force to button control element 106 in the direction of arrow A ( Figure 3), the button control element will remain in the locked position and the depressible member 108 will remain on the barrier 110.
  • the exemplary remote control 100 includes a pair of tension springs 186.
  • the tension springs 186 may be attached to the button control element 106 and to the housing top member 124. The tension springs 186 also help prevent the button control element 106 from being pulled off of the housing 102.

  • the living hinge 188 also biases the depressible member 108 to the position illustrated in Figure 4.
  • the living hinge bias provides an additional level of safety in that simply overcoming the biasing force on the button control element 106 and moving the button control element to the unlocked position will not, in and of itself, result in the button 104 being pressed and a signal being generated. The user must also press the depressible member
