Abstract: An injector fuel injection valve is guided at the lower end by a plastic valve guide mounted in a nozzle containing a valve seat engagable by the valve element. The valve guide includes inwardly protruding annularly spaced ribs having inner guide surfaces and defining spaced flow channels. The guide surfaces engage the circular or spherical exterior of the valve element to guide the element to properly aligned seating against the conical valve seat. The plastic or polymeric valve guide is preferably molded in place within the cup shaped metal nozzle but, if desired, the valve guide may be separately molded and subsequently inserted or snapped in place within the nozzle. A second plastic valve guide may be provided for guiding the upper end of an associated armature.

Abstract: A vehicle seat assembly has a hidden storage compartment disposed in a seat member of the seat assembly. The seat member is pivotally connected to a support mounted on a vehicle floor and is pivotable between forward and rear positions. The seat member has a seating side which faces upward in the rear position and an oppositely facing storage side which faces upward in the forward position. The storage side includes a recess in the seat member internally defining a storage compartment and has an openable cover normally closing the storage compartment and openable to allow access thereto. The cover forms a storage floor surface when the seat member is in the forward position. The assembly has a releasable latch for retaining the cover in a closed position and preventing spilling of the contents therefrom when the seat member is inverted in the rear position. When the seating member is in the rear position, the storage compartment is hidden from view.

Abstract: The connector assembly includes a housing that carries a flexible circuit member and two slide members with slide cam surfaces. A daughter board is secured to one surface on the housing and is electrically connected to the flexible circuit member. The cam surfaces on the two slide members engage cams on a mother board. Movement of the slide member cam surfaces relative to the cams on the mother board moves the housing relative to the mother board and forms an electrical connection between the flexible circuit member and the mother board. A linkage system moves both slide members to form and maintain the electrical connection between the flexible circuit member and the mother board.

Abstract: A method and device for verifying whether a cavity (16) enclosing a micromachined sensing structure (14) between a pair of wafers (10, 12) is hermetically sealed by detecting the presence of moisture within the cavity (16). The method entails forming a bare, unpassivated PN junction diode (20) in a semiconductor substrate, preferably a device wafer (10) with the sensing structure (14). The device wafer (10) is then bonded to a capping wafer (12) to enclose the PN junction diode (20) and micromachine (14) within a cavity (16) defined by and between the wafers (10, 12). The reverse diode characteristics of the PN junction diode (20) are then determined by causing a reverse current to flow through the diode (20). For this purpose, either a known voltage is applied across the diode (20) and the reverse leakage current measured, or a known reverse current is forced across the diode (20) and the voltage measured.

Abstract: An automotive air conditioning system mode control film belt that uses a single drive shaft to shift the belt back and forth. The belt follows a continuous loop that begins and ends at the single drive shaft, wrapping around idler rollers, where necessary, to maintain defined runs of the belt against one or more vent windows in a housing. Thin, long, and widely spaced pairs of drive bands at either end of the belt wrap around the single shaft in opposite directions, clear of one another, wrapping or unwrapping from the shaft in opposite directions as it turns in either direction. The belt is thus able to shift back and forth to open or close the vent widows, while air is able to flow unobstructed between the widely spaced belt drive bands and out to the vent windows.

Abstract: A method by which semiconductor wafers (10, 12) can be solder bonded to form a semiconductor device, such as a sensor with a micromachined structure (14). The method entails forming a solderable ring (18) on the mating surface of a device wafer (10), such that the solderable ring (18) circumscribes the micromachine (14) on the wafer (10). A solderable layer (20, 26, 28) is formed on a capping wafer (12), such that at least the mating surface (24) of the capping wafer (12) is entirely covered by the solderable layer (20, 26, 28). The solderable layer (20, 26, 28) can be formed by etching the mating surface (24) of the capping wafer (12) to form a recess (16) circumscribed by the mating surface (24), and then forming the solderable layer (26) to cover the mating surface (24) and the recess (16) of the capping wafer (12).

Abstract: A head up display system having a diffusing image plane or diffuser. The light output of a relatively small image source is imaged on the diffuser by way of imaging optics. A mirror is used to image light from the diffuser onto a windshield and correct for distortion caused by the windshield. The diffuser is advantageously used when a large field-of-view is desired, or sun load characteristics need to be addressed. The diffuser may be flat or curved in order to optimize the system for different applications. The magnification of the mirror may be made relatively low, and the solar energy density that is made incident on the image source is reduced, providing for a low cost, high performance, color head up display system.

Abstract: A broadband FM antenna is suitable for mounting on an inner surface of a rear window glass of a motor vehicle above an electric rear window defogger grid also mounted on the glass and made of the same frit material. The antenna has an extended range of reception across a commercial FM band without the need for an antenna boost amplifier and is capable of use in multiple countries having different commercial FM bands. The antenna comprises a plurality of horizontal frit lines extending outward from a series of points near the horizontal center of the rear window as described and claimed herein. Some of these horizontal elements are joined by outer connecting frit lines at their outer ends and all are connected at their inner ends by a plurality of inner connecting elements connecting all of the points together. The frit lines essentially form a pair of horizontal antenna elements, each tuned to one quarter of a different commercial FM band wavelength so that the antenna spans the desired band or bands.

Abstract: Pressure sensors on the bottom surface of a seat cushion respond to occupant weight. A microprocessor evaluates the sensor outputs according to total force, load rating, long term average, sensor groups and a fuzzy measure to discriminate between large and small occupants and allow air bag deployment for large but not small occupants. Allow and inhibit decisions are filtered avoid sudden response to transient pressure changes on the seat. When a large occupant is positively detected, an allow decision is locked in place as long as total force exceeds a threshold.
