Abstract: A battery terminal adaptor that may be used to create an auxiliary top terminal post (positive or negative) at a location on a battery cover different from the location of the original top terminal post (positive or negative) is disclosed. The battery terminal adaptor includes: an electrically conductive body having a collar with an opening that is dimensioned so that when the battery terminal adaptor is installed on the battery, the collar can be placed over the original battery terminal post of the battery such that at least a portion of the collar contacts the battery terminal post; an adaptor terminal post upstanding from the body; and an extension member connecting the collar and the adaptor terminal post in spaced apart relationship. Also disclosed is another version of a battery terminal adaptor that can be installed on a battery having a positive top terminal post and a negative top terminal post to reverse the orientation of the top terminals.

Abstract: A switch for controlling the supply of current from a battery cell in a cell cavity to a battery terminal in a battery casing is disclosed. The switch includes a mounting base, a first buss bar connected to the mounting base and connectable to the battery cell, a second buss bar connected to the mounting base and connectable to the battery terminal, and a relay having open and closed positions. The relay includes a third buss bar that places the first buss bar and the second buss bar in contact to provide current from the battery cell to the battery terminal when the relay is in the closed position. The relay is moved into a latched open position when a first winding of a coil of the relay is energized by electricity, and is moved back into a latched closed position when a second winding of the coil is energized.

Abstract: A vehicle anti-theft system that disables a vehicle engine upon detection of an unauthorized vehicle start-up, after the engine is running, by disconnecting the vehicle battery and draining the vehicle electrical system voltage to ground through a resistor. When the system is armed, it monitors whether the engine is running and has been recently started by detecting vibrations, fluctuations in the VES voltage, and the actual VES voltage. The system includes an electro-mechanical switch that has a battery internal contact, a vehicle electrical system, the standard battery external terminal, contact and a disconnect contact. When the switch is connected to the battery contact, the vehicle battery is connected in the circuit. When the switch is connected to the vehicle electrical system contact, the system is connected to ground through a resistance and the battery is disconnected from circuit.

Abstract: A vehicle anti-theft system that disables a vehicle engine upon detection of an unauthorized vehicle start-up, after the engine is running, by disconnecting the vehicle battery and draining the alternator voltage to ground through a resistor. A fob transmitter transmits a coded frequency signal that is received by a receiver associated with the anti-theft system to arm the system. When the system is armed, it monitors whether the engine is running and has been recently started using a combination of vibration detection, voltage fluctuations in the battery voltage and the actual battery voltage. If the system determines that the engine is running and has been recently started, the system will issue a first command that opens a relay switch to disconnect the battery and a second command that closes a switch to connect the alternator to ground through the resistor.

Abstract: A signal representing the RPM of an internal combustion engine is produced by a signal processor connected to the battery of the vehicle. The signal processor derives an electrical signal from the battery which contains signal components produced by operation of the vehicle ignition system, as well as components from a multitude of other sources such as the voltage regulator, fans, air conditioning and other electrical systems of the vehicle. The signal processor filters and signal processes the signal derived from the vehicle battery to produce a signal having a frequency which is related to the RPM of the engine.
