Abstract: An indication system (10) for a vehicle (11) includes a radio frequency circuit (12) with a transponder (84) and an in-vehicle RF tagged element (18). The transponder (84) transmits a status request signal. A first radio frequency identification tag (84) is coupled to the in-vehicle RF tagged element (18). The tag (84) inductively generates a current status signal associated with the in-vehicle element (18) and in response to the status request signal. A method of tracking, identifying, and determining the presence and status of an in-vehicle RF tagged element (18) includes transmitting a status request signal. The status request signal is inductively received via multiple radio frequency identification tags (84, 86) that are associated with the in-vehicle RF tagged element (18). A current status signal is transmitted from the radio frequency identification tags (84, 86). An in-vehicle task is performed in response to the current status signal.

Abstract: A multi-layered sports playing field including a top layer made of substantially artificial material simulating a natural playing surface such as grass and a padding layer positioned between the top layer and the base or dirt layer. The padding layer is made of a plurality of discrete beads of substantially elastic, resilient material (e.g., foam) with portions of adjacent beads abutting one another and other portions being spaced from each other. Substantially all of the adjacent beads are preferably integrally joined (e.g., glued, fused) together at their abutting portions. The padding layer is very porous and breathable and preferably includes feet members supporting the main body of the padding layer above the base or dirt layer to create a water channel of interconnected portions to enhance water drainage to the sides of the field.

Abstract: A fuel pump is provided having improved efficiency by lowering the wet circle index of the pump while maintaining robust axial clearances to meet the demands of an automotive application. One embodiment includes a fuel pump for pressurizing fuel for delivery to an engine of a motor vehicle. The fuel pump generally comprises a housing, a motor, a single sided impeller, a cover and a body. The provision of a single sided impeller greatly reduces the wet circle index and improves the pump efficiency. The cover, impeller, and body are structured to axially balance the impeller which is free floating on the shaft of the motor.

Abstract: A valve includes a valve body, a flux tube, and a winding. The body defines first and second passageways, and a circular opening is defined in the second passageway providing fluid communication between the passageways. The flux tube has a closed end, an open end, and a hollow armature receiving section. The open end is in fluid communication with the first passageway. A spherical armature is disposed in the armature receiving section for reciprocating movement between a closed position sealing against the circular opening to prevent communication between the passageways and an open position spaced apart from the opening permitting communication between the passageways. The winding is disposed about the flux tube for electromagnetically positioning the armature. The flux tube forms a fluid tight pressure boundary between the winding and the passageways. A spring urges the armature toward one of the open position and the closed position.

Abstract: The invention relates to a brake arrangement for a land vehicle comprising the following characteristics: an electric motor with a downstream connected (reduction) gear which acts on the friction pads of a brake arrangement, with the gear being designed self-locking, and an actuation mechanism by means of which the self-locking function can be cancelled or established.

Abstract: A multifunction switch assembly includes a handle having an actuator mounted at an inner end. The actuator and handle are pivotally mounted in a housing. First and second return springs mounted in the housing bias the actuator towards the neutral position from the left and right turn positions, respectively. The first return spring preferably imparts a higher force against the actuator than the second return spring, in order to counter the effects of gravity acting upon the handle. The first and second return spring preferably both impart opposite forces on the actuator when in the neutral position in order to eliminate play.

Abstract: A linkage assembly for use with kinetic mechanisms such as an automotive seat assembly having an elongated torsion rod made of either a solid bar or a hollow cylindrical tube, and at least one linkage member having an aperture corresponding to the cross-sectional profile of the torsion rod and adapted to receive the torsion rod therethrough. The linkage member includes an essentially flat sheet of metal extending from and coplanar to the aperture and an outwardly extending extruded metal flange which projects upward from the flat surface of the linkage member. The extruded flange defines a sleeve through which the torsion member extends. A weld seam is located at the terminal end of the flange in attaching contact between the torsion rod and the flange to form a secure union between the two members.

Abstract: A laser gauge for measuring the thickness of glass panes and the spacing between glass panes in a sealed insulated window. A laser beam is directed at a predetermined angle to a first glass surface. Reflections from the glass surfaces pass through a gauge housing, through a slot in an adjustable slide, and impinge on a matted finished surface of thin scale. The housing and the slide are formed from materials having a predetermined coefficient of friction relative to each other to provide smooth movement to said slide in said housing. The scale is sufficiently thin to avoid false readings from internal reflections within the scale. The scale is adjustable on the slide to align the first reflection with a reference indicia. For each glass pane and for each pane spacing, the slide is adjusted so that a first surface reflection aligns with the reference indicia and a second surface reflection is compared with indicia on the scale to determine the thickness of the glass pane or the glass pane spacing.

A formula is provided for determining a range of dimensions for the head and foot ends, and the head section, and the foot section.

Abstract: A portion of a solenoid coil melts after a predetermined time period has elapsed to interrupt the flow of current through the coil. The portion which melts can include a reduced cross sectional area which increases the resistance of the portion of the wire. Alternately, a portion of the coil wire can be formed from a material having a higher resistivity than the remainder of the wire.

Abstract: An improved yoke for use in a universal joint is described having a plurality of axially-extending grooves formed therein. The grooves are formed in the outer cylindrical surface of the sleeve portion of a yoke connected to an end of a vehicle driveshaft so as to permit access of a nut runner or other suitable tool for tightening the fasteners used for securing the retaining device to the other yoke used in the universal joint. The number of grooves provided is dependent on the number of fasteners used to secure the retaining device to the other yoke used in the universal joint. The length, width, and depth of the grooves may vary depending on a number of factors including the clearances between the yokes and other adjacent vehicle components and the type of tool required to secure the retaining device to the yoke. The axially-extending grooves are formed in the yoke such that a fastening tool will be aligned with the retaining device fasteners when the tool is positioned in a groove.
