Abstract: The Audio Illuminator is an integrated system providing directed lighting and a public address type amplification and loudspeaker capability, under control from a remote location. The system includes a searchlight and one or more directional, high-power loudspeakers. An audio amplifier supplies drive signals to the loudspeakers in response to audio input signals received from the remote control. The system includes a power junction box for supplying power to the amplifier and the searchlight and carrying signals to and from the various components. The system may derive power from a small portable diesel generator. A gimbal mount supports the searchlight for two-directional movement (horizontal rotation and vertical tilt angle rotation) and supports the one or more loudspeakers for movement with the searchlight in at least one of the two directions. Drive motors provide two-dimensional automatic positioning in response to signals from the remote control unit.

Abstract: The terminal voltage of nickel-cadmium battery is measured while the battery is placed under a heavy discharge load during a predetermined short interval.
Abstract: A discharge circuit reduces the state of charge of a battery to a nominal zero so that the battery can be put through one or more complete charge/discharge cycles.
