Patent number: 7113078Abstract: An emergency lighting system that can be used on any vehicle where the standard lighting system installed on the vehicle is malfunctional, especially at the rear of the vehicle, due to shorting out or other causes. The emergency lights consist of units having various colored lights therein, such as red, white or yellow that are normally recognized in any traffic pattern. The lights can be operated from the standard battery of the vehicle or can be switched to a battery system contained in the light units. This is especially true in vehicles towing a boat or a trailer. When the boat is launched into the water, the lights on the trailer may be submerged into the water thereby shorting out the electrical system. This renders the towed vehicle illegal in traffic on the highway because the rear lights are not functioning. The inventive concept of this invention solves the above noted problem.Type: GrantFiled: June 30, 2004Date of Patent: September 26, 2006Inventor: Allan Wymer Young

Publication number: 20030080621Abstract: An automotive electrical system protection device protects the wiring of a direct current electrical system should a short circuit scenario occur. Moreover, the same protection device independently detects and guards again battery voltage depletion due to low current drain or run-down caused by faulty accessory loads or such loads being left on after the engine of the vehicle and associated generator are shut-off. The protection device has a run-down relay which opens upon prolonged low current conditions which causes battery voltage to deplete below a threshold voltage necessary to start the engine. Upon starting of the engine, the run-down relay, if open, will automatically close to permit power to the starter motor. During high current or short circuit conditions, a high current relay will open to protect the wiring of the electrical system including that of a primary conductor wired directly between the battery and the starter motor.Type: ApplicationFiled: August 7, 2002Publication date: May 1, 2003Inventor: John B.

Patent number: 6548916Abstract: When a voltage larger than a voltage from a 12-V power supply (11) and capable of on/off controlling an n-channel MOSFET (15) is supplied to a simple ON/OFF circuit (19), the simple ON/OFF circuit (19) outputs to the gate G a control signal that on/off controls the n-channel MOSFET (15) by the supplied voltage, thereby performing on/off control of the n-channel MOSFET (15), and enabling control of electrical power supplied to a load (13) from the 12-V power supply (11). The 36-V power supply (17) is used for on/off control of the n-channel MOSFET (15), so as to supply the output voltage from the 12-V power supply (11) to the load (13).Type: GrantFiled: February 25, 2000Date of Patent: April 15, 2003Assignee: Yazaki CorporationInventors: Akiyoshi Kanazawa, Makoto Uda

Patent number: 6541151Abstract: A battery assembly system used for an electric vehicle having a configuration in which electrolyte is not released from an exhaust passage even if the electrolyte is released in a mist state from a cell. A battery assembly case is provided behind a rear seat in a cabin. An exhaust duct having a cooling fan is connected to the battery assembly case, and an air inlet port is provided to the battery assembly case at the side opposite to the portion where the exhaust duct is connected. As the cooling fan, a sirocco fan or an axial-flow fan is used. The air for forcibly cooling the battery assembly is allowed to flow in the cabin, the air inlet port, the battery assembly case, the exhaust duct, the cooling fan, and the exhaust duct in this order. A mist state electrolyte released from the cell together with the air is allowed to collide with and is attached to a cascade of the fan or the wall surface of the fan.Type: GrantFiled: March 30, 2001Date of Patent: April 1, 2003Assignees: Matsushita Electric Industrial Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Keiichi Minamiura, Toshiaki Nakanishi

Patent number: 6515455Abstract: A combination battery includes a plurality of cells connected together in series. A switching element operates for selectively blocking and unblocking a power feed path between the combination battery and a load. The switching element is changed to its on state when receiving a drive voltage. When a starting switch is moved to its on position, a drive circuit is connected with at least one cell among the cells in the combination battery and uses the at least one cell as a power source to generate the drive voltage applied to the switching element. A power supply circuit receives an output voltage from the combination battery and starts to operate when the switching element is changed to its on state. At a later moment, a power source for setting the switching element in its on state is changed from the at least one cell to the power supply circuit.Type: GrantFiled: August 24, 2001Date of Patent: February 4, 2003Assignee: Denso CorporationInventor: Seiji Hidaka

Patent number: 6512310Abstract: An electro-mechanical impact detecting device for a vehicle is provided which implements a multi-stage control for vehicle occupant protection systems and improves the operational delay characteristics of the vehicle occupant protection systems at an irregular collision based on the setting of multiple impact levels which are detected. When a main rotor rotates by a certain amount against the exertion force of a moving contact, the moving contact and fixed contact close the circuit, thereby detecting the first impact level. When the main rotor further rotates against the exertion force of the torsional coil spring, the remaining two pairs of fixed contacts and close the circuits sequentially, thereby detecting the second and third impact levels, respectively.Type: GrantFiled: October 27, 2000Date of Patent: January 28, 2003Assignee: Denso CorporationInventor: Jun Ohnishi
