Abstract:
A method for massaging a user contacting a pad, using electrical power from a source having a voltage drop as loads are added, the method comprising the steps of:(a) providing a plurality of eccentric motor vibrators in respective regions of the pad;(b) providing a microprocessor controller, an array of input elements for interrogation by the controller, and a plurality of drivers for powering the vibrators from the power source in response to the controller;(c) interrogating the input elements by the controller to determine an intensity control value and vibrators to be activated;(d) determining a maximum duty cycle being a base duty cycle plus a load increment duty cycle for each of the vibrators to be activated; and(e) periodically activating the drivers for producing respective operating duty cycles of activated motors being responsive to the intensity control value and limited to the maximum duty cycle.
