Abstract: An automatic override circuit is responsive to the magnitude of instantaneous current flow through a monitored conductor to produce an output signal which can actuate a solenoid or a ground fault interrupter to automatically trip a circuit breaker in repsonse to an excursion of current flow which exceeds a predetermined maximum current overhead level. The short circuit protector can automatically override a thermal trip delay and cause the circuit breaker to trip instantly or delay tripping for a prescribed period of short circuit events which exceed the maximum current overload level. In one embodiment, a control signal is generated which actuates a solenoid which is coupled to a thermal magnetic circuit breaker. In an alternative embodiment, the control signal is utilized for automatically triggering a ground fault interrupter.

Abstract: A heating element for bathroom and similar mirrors is formed as a laminate for placing behind a conventional mirror glass. The laminate has separate foil conductor patterns forming distribution and return conductors for the supply current, and a continuous conductor layer formed by a higher resistivity conducting paint or coating extending between the conductor patterns. Preferably the conductor patterns are formed as longitudinal bands on a continuous web of insulative substrate material which is then cut into lengths which are mounted on backing sheets of appropriate size and which carry buses to establish connection between the conductor bands and an electrical supply.

Abstract: Method and apparatus for verifying the load rating of an active alternating current distribution circuit at a power outlet. The load rating of the distribution circuit is verified by measuring the change in line voltage at the power outlet as different loads are applied. The no-load line voltage is factored out by summing an analog signal derived from the no-load line voltage with a reference voltage to produce a null balance. When the distribution circuit is loaded by a programmed load or by the load of an external appliance such as a resistance heater, the loaded circuit waveform is transformed and rectified to produce a relatively low amplitude no-load direct current waveform. The transformed, loaded circuit waveform and the null balance waveform are summed, amplified and measured. The amplified sum corresponds exactly with the drop in line voltage across the distribution circuit at the power outlet.
