Abstract:
A rectifier circuit includes a MOSFET (M1), and a first Zener diode (D1) or a first Zener-emulator (E1) that emulates the D1. The circuit conducts current in a forward direction from an input to an output, and substantially blocks current in a reverse direction. The M1 is characterized by an on-resistance. A cathode of the D1 or a cathode-contact of the E1 is connected to the input, and the anode of the D1 or an anode-contact of the E1 are connected to the source. The E1 includes a first small-Zener-diode (D11), a first resistor (R11) and a first transistor (M11) interconnected such that the E1 emulates the D1, and is characterized by a Zener-voltage. The Zener-voltage and the on-resistance are selected such that a stored-charge in the body-diode is less than a forward-charge-threshold when current flows in the forward direction, whereby the reverse recover time of the body-diode is reduced.

Abstract:
An electrical distribution center having a base connected to one or several wiring harnesses and a connector body that is configured to be electrically and mechanically connected to the base. The connector body houses electrical devices such as relays, fuses, and control modules. The connector body is secured to the base by a pair of slides having dog-leg shaped slots that engage studs on the base. A single slide lever having two arms attached to each of the slides is pivotably attached to the connector body and the slides and is configured to simultaneously move the dog-leg shaped slots relative to the studs on the base, thereby securing the connector body to the base.
Abstract:
A plurality of heaters is provided where each of the plurality of heaters includes a fuel cell stack assembly having a plurality of fuel cells which convert chemical energy from a fuel into heat and electricity through a chemical reaction with an oxidizing agent. Each of the plurality of fuel cells also includes a conductor electrically connecting the fuel cell stack assembly to an electronic controller which monitors and controls electric current produced by the fuel cell stack assembly. The conductor of one of the plurality of heaters allows electric current produced by the fuel cell stack assembly of the one of the plurality of heaters to be monitored and controlled by the electronic controller independently of the fuel cell stack assembly of at least another one of the plurality of heaters.
Abstract:
A connector assembly including a first and second connector configured to be connected to the first connector. The first connector has a slide including a cam groove for receiving a latch pin defined by the second connector. The slide is moved by a lever such that the cam groove and the latch pin cooperate to draw the first and second connectors from an uncoupled position to a fully coupled position when moved from an initial to final position. A ratcheting mechanism couples the lever to the slide allowing the lever to return from the final position to the initial position without disconnecting the first and second connectors. The lever is configured to move through more than one stroke from the initial position to the final position to bring the first and second connectors from the uncoupled position to the fully coupled position.
Abstract:
A heater includes a heater housing extending along a heater axis. A fuel cell stack assembly is disposed within the heater housing and includes a plurality of fuel cells which convert chemical energy from a fuel cell fuel into heat and electricity through a chemical reaction with a fuel cell oxidizing agent. A combustor disposed within the heater housing includes a combustor fuel inlet for introducing the combustor fuel into the combustor, a combustor oxidizing agent inlet for introducing a combustor oxidizing agent into the combustor, and combustor exhaust outlet for discharging a heated combustor exhaust from the combustor. An anode exhaust conduit is connected to the anode exhaust outlet and extends out of the heater housing for selectively communicating a first quantity of the anode exhaust out of the heater housing. The heater housing is heated by the fuel cell stack assembly and the heated combustor exhaust.
Abstract:
An internal combustion includes a crankshaft and a camshaft rotatable by the crankshaft. The internal combustion engine also includes an oil source, an engine cover, and a drive member disposed within the engine cover for transferring rotational motion from the crankshaft to the camshaft. A camshaft phaser actuated by an electric motor is disposed within the engine cover for controllably varying the phase relationship between the crankshaft and the camshaft. A supply passage communicates oil from the oil source to the camshaft phaser in order to lubricate the camshaft phaser and a drain passage drains oil from the camshaft phaser to the oil source. A sealing arrangement defines a dry zone within the engine cover to isolate the drive member from oil used to lubricate the camshaft phaser. The sealing arrangement includes an electric motor to camshaft phaser seal to seal between the electric motor and the camshaft phaser.
Abstract:
An electronic assembly including a printed circuit board (PCB), a housing, and a shock absorbing device that is intermediate the printed circuit board and the housing. The shock absorbing device is formed of an insulative and compliant material, such as a thermoplastic elastomer material. The side walls of the shock absorbing device defines a groove surrounds and at least partially encloses the edges of the printed circuit board. The shock absorbing device defines an aperture through which a fastener is configured to pass to secure the shock absorbing device to the housing and thus securing the printed circuit board within the housing. The shock absorbing device is intermediate the fastener and the printed circuit board so that there is no direct contact between the fastener and the printed circuit board which could transmit impact shock directly from the housing to the printed circuit board.
Abstract:
An apparatus is configured to shape a flat flexible cable (FFC). The apparatus is configured such that a first end and a second end of the FFC can be positioned, respectively, at a first location and a second location of a circuit board assembly (CBA). The apparatus includes a radiused portion configured to determine a bend radius of the FFC when the FFC is installed into the apparatus. The apparatus also includes a clamp portion configured to urge the FFC around the radiused portion when the FFC is installed into the apparatus.
