Abstract:
An electrical contact includes at least one grooved channel defined in an interior surface of the electrical contact along at least a portion the electrical contact disposed along a longitudinal axis. The portion is configured to axially receive a lead of a wire cable for attachment thereto and thereby allow the attached lead to at least engagingly make contact against a recessed surface of the grooved channel. The grooved channel has a depth and includes at a least one sidewall extending along the depth. The sidewall includes at least one section that angularly extends from the interior surface to a point recessed from the interior surface disposed on the sidewall along the depth.
Abstract:
A camshaft phaser includes a housing with an array of internal splines formed within a bore. A harmonic gear drive unit is disposed within the housing and includes a circular spline and a dynamic spline, a flexspline disposed radially within the circular spline and the dynamic spline, a wave generator disposed radially within the flexspline, and a rotational actuator connectable to the wave generator. One of the circular spline and the dynamic spline is fixed to the housing. A hub is rotatably disposed radially within the housing and attachable to the camshaft and fixed to the other of the circular spline and the dynamic spline. A back plate has an array of external splines engaged in a sliding fit with the array of internal splines for transmitting torque from the back plate to said housing. The back plate also has an input sprocket for receiving rotational motion, in use.
Abstract:
A surface mount interconnection system provides a method and apparatus for mounting an auxiliary printed circuit board assembly directly to a main printed circuit board assembly without the use of leaded surface mount devices. A linear array of spaced-apart solder pads is arranged on an exposed surface of the substrate of both assemblies, with at least one of solder pad arrays being located adjacent an edge of its associated substrate. A selected plurality of aligned cooperating pairs of solder pads are electrically and mechanically interconnected by a solder ball reflowed to form a joint there between. The solder balls comprise a high melting temperature inner core and a low melting temperature outer solder core.
Abstract:
A valve assembly includes a housing with a supply port receiving working fluid from a working fluid source, a control port connected to a working device, and a vent port for returning working fluid to the working fluid source. A spool with a spool bore in fluid communication with the control port controls the flow of working fluid between the supply port and the control port and between the control port and the vent port. An actuator assembly selectively alters the position of the spool. In a high pressure mode, the supply port is in fluid communication with the spool bore at a first pressure. In a pressure relief mode, the vent port is in fluid communication with the spool bore. In a pressure regulating mode, the supply port is in fluid communication with the spool bore at a second pressure which is less than the first pressure.
Abstract:
An electrical connection system and method includes a first connector housing matable to a second connector housing along a mating axis. The first connector housing contains a mating assist lever (MAL) that rotationally pivots between an INOPERATIVE position and a CLOSED position and includes a locking means. When the MAL is positionally rotatable to the CLOSED position the first connector housing and the second connector housing are mated together such that the locking means is disposed adjacent an external surface of the second connector housing. A sufficiently applied force against the locking means actuates the locking means so that the locking means latchingly secures the first connector housing to the second connector housing. A CPA member, also disposed on the MAL, slidingly communicates with the latched locking means transverse to the mating axis and ensures the latched locking means does not become unlatched so that electrical connection system remains mated.
Abstract:
A non-contact gesture recognition system for recognizing gestures made by an occupant of a vehicle using a first multiple-zone temperature sensor equipped with an array of temperature sensors. The sensor outputs an array signal indicative of a zone temperature for each of a plurality of zones within the vehicle. The array may be oriented such that a sample direction on the array arising from the gesture is characterized as diagonal. The sensor may include a multi-focal length Fresnel lens panel formed of a plurality of Fresnel lens elements having various focal lengths.
Abstract:
A switch assembly for the lift-and-slide roof of a vehicle that includes a housing, an actuating element, a first pair of movable electrical switching contacts, and a second pair of movable electrical switching contacts. Each longitudinal wall of the housing comprises a cross-shaped groove including a cross-shaped guiding track. The cross shaped groove receives a projecting member of the actuating element. The guiding track receives a pressure piece carried by the actuating element. The cross shaped groove has end surfaces which form abutment surfaces for the corresponding surfaces of the projecting member.
Abstract:
An air conditioning system having an improved internal heat exchanger (IHX) assembly. The IHX assembly includes an elongated cavity for low pressure refrigerant flow from an evaporator and an interior tube disposed within the cavity for high pressure refrigerant flow from a condenser, and a pressure equalization passage between the low and high pressure sides. The passage is large enough to allow pressures to equalize between the condenser and evaporator while the air conditioning system is inactive, so as to prevent the pressure differential that would otherwise enable the loss of refrigerant oil from the compressor, and small enough not to effect the operation of the air conditioning system. The pressure equalization passage may be a by-pass valve assembly having a reed portion that is normally open when the air conditioning system is inactive and closed when the air conditioning system is active for maximum cooling efficiency.
Abstract:
An eVCP camshaft phaser comprising a harmonic gear drive unit having a circular spline and a dynamic spline linked by a common flexspline, and a single wave generator disposed within the flexspline. The circular spline is connectable to either of a crankshaft-connectable sprocket or an engine camshaft, the dynamic spline being connectable to the other thereof. The wave generator is driven selectively by an eMotor to cause the dynamic spline to rotate past the circular spline, thereby changing the phase relationship between the crankshaft and the camshaft. A coaxial coil spring is connected to the sprocket and to the phaser hub and is positioned and tensioned to bias the phaser and camshaft to a stop position wherein the engine can run or be restarted after the eMotor is de-energized. Preferably, the spring comprises a spring cassette for easy assembly into the eVCP.
Abstract:
An anti-backlash assembly of the type for transferring motion via a pin movable along a slot. The assembly comprises a pivot lever and a second lever member. The pivot lever comprises a body portion and a pivot lever portion extending from the body portion to a pivot lever distal end. The pivot lever portion defines a pin engagement slot extending from adjacent the pivot lever distal end toward the body portion. A pair of fingers extend in parallel and spaced relationship from the pivot lever distal end of the pivot lever portion toward the body portion to engage opposite sides of a pin of the engagement arm. Each of the fingers includes a pin engaging section extending to an inwardly extending distal end and a spring section extending in a for urging the fingers into clamping engagement with the pin.
