Abstract
A massaging system includes a pad; a heater element, and motorized vibrators in respective regions of the pad; corresponding heater and motor drivers in the pad; a control wand removably connectable to the pad and having a microcontroller with RAM and ROM, a serial EEPROM; a serial interface to a shift register in the pad for signaling pulse width modulation of the drivers. The ROM defines a master set of operating modes and variations thereof in response to operator input of intensity, region, heat input; and mode signals to the controller. The EEPROM has data for implementing and configuring a subset of the master modes. The system can also provide composite modes including a test mode that automatically sequentially activates each mode and variation of the subset of the modes without delays for exercising non-implemented modes. The system can have a power detector for identifying sources of power having different current limitations, the system being operated with PWM duty cycle limiting when raw power voltage falls below a preset level. Also disclosed is a set-up method for writing data to the EEPROM using the serial interface when the wand is disconnected from the pad for faci…
