Abstract: An electrical control system for an automotive vehicle can be switched to a service facility operating mode in which locks for the glove compartment, a storage console and the trunk can be inactivated in their closed position while other electrically-operated vehicle locks remain operable by actuators of the control system to prevent access to personal belongings by service personnel. Restoration to the normal operating mode can be effected automatically upon lapse of a time period programmed into the central unit.

Abstract: A simplified dual connection system electrically interconnects the vehicles of a train. The train features a trainline to be formed through series interconnection of a wire on each vehicle. The simplified dual connection system includes a central computer, a connector control device on each vehicle and a pair of mateable connectors between each pair of vehicles of the train. Each pair of mateable connectors electrically interconnects the wires of each pair of adjacently disposed vehicles to form the trainline. When the mateable connectors are mated, a primary electrical path and a redundant electrical path are formed in that pair of connectors for the trainline. Each connector has a bidirectional circuit that interconnects a main node and a backup node for the wire on the vehicle.

Abstract: An apparatus and method for disarming an automobile alarm system uses the ignition switch of the automobile to create a sequential pulse access code. Toward this end, two commonly available electrical circuits in the vehicle's wiring that are switched on and of by the shifting of a vehicle's ignition switch among power-applying switch positions serve to supply a pulse code of sequential electric pulses to the alarm system to perform a selected function, including entering a valet mode or overriding and disarming the system without a remote control transmitter. Because the shifting of the ignition switch generates a two-wire detectable pulse code, previously-programmed pulse codes can be selected to perform different functions in addition to disarming the system, including using pulse codes to trigger entry of the system into a learning mode.

Abstract: A central-locking system is reset upon loss of a portable remote-control unit and replacement by another in a system in which a diagnostic device is temporarily connected and switched to the stationary part of the locking system into a "SETUP" mode. The key is then inserted into a key-operated switch to interrogate the transponder with the transceiver and from the latter the key-identification code word stored in the transponder and the transponder initial code word are transferred. The key-identification code word and transponder initial code word are stored in a code-word memory and the transmitter is then operated to send a remote-control changing code word to the receiver and enables switching back to the "NORMAL" mode of operation and removal of the diagnostic device.

Abstract: Vehicle cranking management systems and methods are provided for a vehicle preferably including a tractor mechanically connected to a trailer. Electrical energy is enabled to transfer from a battery of the vehicle to an electrical accessory load, when a battery output voltage signal is above a first predetermined threshold voltage, but is inhibited from transferring from the battery to the electrical accessory load if the battery output voltage signal is below a second predetermined threshold voltage. The first and second predetermined threshold voltages may be determined responsive to a sensed temperature of the vehicle engine, preferably a sensed temperature of oil present in the engine. In addition, electrical energy is enabled to transfer from the battery to a starter which cranks the vehicle's engine if a cranking command signal to crank the engine is asserted for less than a first predetermined time interval.

Abstract: A high voltage generator including a Marx Generator (1) provides an output of up to 200 kV at a pulse repetition rate of up to 1 kHz. Discharge is triggered by over-volting a first stage (2a) of the Marx Generator, each stage including a hydrogen spark gap switch (5). By inhibiting the charging power supply (7) for a short time after each discharge, recovery of the dielectric is ensured, enabling high repetition rates without the need for gas flow.

Abstract: A firing circuit for multiple vehicle passenger restraint initiators, wherein initiators located in proximity to each other are paired in first and second parallel connected firing loops terminated by first and second firing circuit nodes. The first firing loop includes one of the initiators and a first diode poled to conduct current from the first node to the second node, and the second firing loop includes the other initiator and a second diode poled to conduct current in the opposite direction, that is, from the second node to the first node. A switching circuit, such as a four-element bridge couples each pair of firing loops to a source of DC so that the source voltage can be applied to the firing loop nodes in either polarity, depending on whether the switching circuit receives a first firing signal or a second firing signal.

Abstract: A device for transmitting data or energy supply from or to a transponder, especially for an anti-theft system in a motor vehicle, includes an antenna oscillating circuit which is induced to oscillate by an exciter variable. The oscillation is transmitted by transformer coupling to a transponder oscillating circuit. In order to make the transmission of energy or data as effective as possible, the current or the voltage in the antenna oscillating circuit is measured and compared with a desired variable. Upon a deviation, a correction value is generated by which the exciter current is increased or the resonant frequency is adapted to the exciter frequency as a consequence of the addition of an impedance to the antenna oscillating circuit.

Abstract: A triggering pin is connected between the steering column cover and the ignition switch lock, or a glass bead is held between the ignition switch lock and the ignition switch lock mounting assembly, of an automobile including a steering column lock. When either the steering column cover in the area of the ignition switch lock or the ignition switch lock itself is removed, the triggering pin or bead, connected to a trigger wire, triggers a switch that removes power from a propulsion system function necessary for the driving of the vehicle. In addition, where the automobile includes a conventional security system, the triggering of the security device trips a switch to provide power to the conventional security system. Power may also be provided to a hood lock spliced onto the hood release cable that, when actuated, prevents the cable from moving.

Abstract: A system selectively completes a horn circuit through which electrical power is provided to a horn in an automobile. A relay is connected to a power supply and completes the horn circuit when a current signal passing through the relay has at least a threshold magnitude. A relay driver is selectively activated by processing circuitry. When it is activated, the relay driver is in a conductive state, and when it is not activated, the relay driver is in a high impendance state. When the relay driver is in the conductive state, it places the relay in series with a low potential conductor thereby establishing the current signal at at least the threshold magnitude. The processing circuitry is electrically connected to a manually actuated sensor, which may be a flexible potentiometer. The processing circuitry activates the relay driver when the manually actuated sensor is actuated.

Abstract: A touch sensor circuit is disclosed for sensing a person's touch and for switching power to an AC load. The touch sensor circuit includes a sense input circuit, logic circuit, power switching circuit and power supply/reference circuit. The power supply and reference circuit tracks the AC line-hot input, and supplies DC power to the circuit. The sense input circuit is configured such that when a person touches the touch input pad, a circuit is created between the positive voltage reference and earth ground, thereby generating an easily detectable voltage swing on an internal sensing node. The logic circuit senses the voltage variation on the sensing node and generates a pulse which toggles power to the power switching circuit and connected load.
