ABSTRACT:
A system for controlling power in a remote signalling device includes an electronic controller, a transmitter portion and a signal conditioning portion. The electronic controller preferably determines the characteristics of the desired transmitted signal and provides information regarding those characteristics to the transmitter portion. The electronic controller also provides a power control signal to the transmitter portion. The controller determines the characteristics of the power control signal depending on the characteristics of the desired transmitted signal and other preselected factors. The power control signal preferably is processed by the signal conditioning portion so that it provides the desired voltage to the transmitter portion. The power control signal regulates the signal strength from the transmitter portion so that more consistent and effective communications are provided to accommodate a variety of transmitted signals and varying operating conditions over the life of the remote signalling device.
