Abstract: An automobile alternator and voltage regulator test apparatus which may be connected to the electrical system of a car without altering the existing wiring. The test apparatus analyzes the waveform and magnitude of the ripple voltage superimposed on the alternator output, and also senses the voltage level present at the field terminal of the alternator. In response to the detected ripple characteristics and measured field voltage, the device provides an unambiguous visual indication of which components, if any, are malfunctioning.

Abstract: A solid state relay is described which exhibits gradual turn-on characteristics. This relay is useful, for example, for turning ON and OFF traffic control signal lights, wherein the gradual turn-on characteristics of the relay significantly reduce the current surge normally associated with the turn-on of incandescent lamps.
