Programmable timer power switch unit with emergency override reset
First Claim
1. A programmable timer power switch unit having an emergency override reset, said unit comprising:
- power switch means receiving power from a motor battery and switching the power to equipment powered by the motor battery;
detector means connected to the motor battery for detecting potential charges of the battery and comparing the detected potential charges to predetermined reference voltages;
vibration/sound/pressure detector connected to said detector means for monitoring the comparison of the voltages with vibrations of the motor battery, and providing a mode signal representing battery on, idle or moving;
auto/manual override switch connected to said detector means for receiving a comparison signal and for sending a result signal based on the comparison;
timer-control logic receiving the signals from said vibration-pressure detector and said auto/manual override switch for controlling said power switch means based on the received signals; and
programmable delay means connected to said timer-control logic and said auto/manual override switch for enabling said timer-control logic for a pre-determined selected time.

Abstract
A programmable timer power switch unit with emergency override reset for use with a battery includes a power switch which receives power from the battery and switches the power to equipment. The unit also has a plurality of voltage detectors connected to the battery to detect a plurality of voltages and a vibration-pressure detector which detects any movement of the motor. There is a timer-control logic which is connected to the components and disables the power switch when voltage problems are detected. The unit further includes a programmable delay switch. The purpose of this switch is to allow the equipment to run during a pre-selected time. Also, there is an auto/manual override switch for overriding the timer-control logic and providing a short delay time prior to disconnecting the unit in order to protect any memory intensive electronic equipment from intermittent drop-outs such as when the engine is started.

9. A programmable timer power switch unit for use with a battery and an engine, said unit comprising:
-
power switch means receiving power from the battery and switching the power to equipment powered by the battery; voltage regulator receiving voltage from the battery and detecting current for regulating the voltage to maintain a minimum voltage to be consumed by the equipment; motor detector receiving voltage from the battery, said motor detector detecting the battery is ON and at a specific level of charge; vibration-pressure detector receiving a signal from said motor detector indicating the battery has the specific level of charge and detecting a mode of the battery means; auto/manual override switch connected to said motor detector for receiving a signal that the battery is ON and at said specific level of charge; timer-control logic receiving signals from said auto/manual override switch and said vibration-pressure detector, said timer-control logic determining from the received signals whether a fault exists, if said fault exists, said timer-control logic disables said power switch; and programmable delay means connected to said timer-control logic and said auto/manual override switch for enabling said timer-control logic for a pre-selected time. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
