ABSTRACT:
A massaging apparatus utilizing a hand held controller includes a microcontroller to actuate a plurality of vibrators positioned within a cushion using pulse width modulated signals. The microcontroller is programmed such that each zone may be actuated independently and continuously, simultaneously and continuously, or sequenced at a selectable rate controlled by the user. The hand held control uses multiplexing of the switch inputs and LED outputs to control twelve LEDs and five vibrating motors via eight switch inputs using a microcontroller having only thirteen I/O lines. A warning timer is also provided to remind the user that the device is turned on at periodic intervals.
