ABSTRACT:
A computer controlled massaging system includes a pad; a plurality of motorized vibrators in respective regions of the pad; a heater element in the pad; a microprocessor controller; an array of input elements responsive to operator input for signaling an intensity control value, at least one region signal relating motors to be activated, and a heat control input; and a plurality of motor drivers and a heater driver responsive to the controller. The motors can be variably driven using pulse-width modulation, with duty cycle compensation for voltage drops resulting from added loads, and with current limiting when, for example, the system is powered from an AC line using a low-voltage transformer of limited capacity. Also disclosed is a corresponding method for massaging. The system can have a power detector for identifying sources of power having greater and lesser voltage drops as loads are added, the controller being programmed for increasing a base duty cycle and reducing a load increment duty cycle during operation from the power source of lesser voltage drop. A configuration selector can signal particular components being electrically connected in the system for utilizing a single set of programmed instructions in the program memory in variously configured examples of the massaging system. The system can also include an audio detector having an audio mode input element for selectively activating the motors in response to a detected envelope of an external audio signal. The system can also include a test mode that automatically sequentially activates components of the system.
