Abstract: A system for generating electrical power signals from a fluid fuel source. The system comprises an engine and a generator. The engine burns the fuel and is connected to the generator such that the generator generates a raw power signal. An output stage generates an output power signal from the raw power signal. A control circuit controls the operation of the engine based on the output power signal. The control circuit further controls the operation of the engine based on an output current of the generator when this output current exceeds a current threshold level. The control circuit additionally controls the operation of the engine based on a temperature of the engine when the engine temperature exceeds a rated temperature level. The system thus generates sufficient power to supply a variable load but stays within an operating range defined by a rated power level and the rated temperature level.

Abstract: In a cable television system in which one or more tap-off devices deliver television signals to an associated subscriber via drop cables connecting the tap-off devices at the subscribers' premises, and in which the tap-off devices receive electrical power from the subscribers via the drop cables, a power safety apparatus and method interrupts the application of power to the drop cable when the drop cable becomes cut, broken or disconnected to prevent individuals from receiving hazardous electrical shocks.
