ABSTRACT:
A usage monitor is provided for electrical appliances, primarily for televisions, which keeps track of appliance usage during a moving time interval, such as the week immediately prior to the instant moment, and provides a readout of a number of hours per unit time that the device has been on. In the television implementation illustrated and claimed, a power interfacing box is used into which the television plug is inserted, and the box has a key-operated switch which enables the time monitoring to be temporarily deactivated in the event the parents wish to watch some television.
