Abstract
A self-monitoring power supply can be incorporated into electrical devices which are part of a multi-device communication system. The power supply is energized by electrical energy received from a medium on an intermittent basis. The self-monitoring circuitry assures that the device has sufficient energy for carrying out its functions. Noise rejection and noise immunity can be enhanced in such devices by circuitry which upon detection of a transmission start signal or a clock pulse locks out data signals for a predetermined period of time and upon detection of a data signal locks out transmission start or clock pulses for a predetermined period of time.
