Abstract: A method for adjusting a plurality of vehicle cockpit devices via a two-part process that utilizes device position constraints to determine candidate arrangements and then, ultimately, recommended arrangements of the vehicle cockpit devices to determine a desired setting of the various devices. The position constraints are determined using positioning data obtained from an occupant. An exploratory search routine is used to determine the candidate arrangements with the cockpit devices being moved to each candidate arrangement so that the occupant can be queried concerning the desirability of each such arrangement. The occupant's responses are then stored for later retrieval. Thereafter, a plurality of recommended arrangements of the cockpit devices are determined using a meta-heuristic pattern search along with a neural network search accelerator that permits screening of each recommended arrangement.

Abstract: A friction stir rivet is rotated in a precessing motion and driven through a first fusible workpiece into an engaged second fusible workpiece, causing local portions of the first and second workpieces to plasticize. When the rivet is driven through the first workpiece and into the second workpiece, rotation is stopped and the plasticized material solidifies around the rivet creating an enlarged weld joining the metal workpiece and encompassing the rivet, which provides additional mechanical strength.

Abstract: The present invention is a self-piercing rivet wherein the hollow shell has an external axial asymmetry wherein the asymmetry is with respect to the axis of rotation of the hollow shell. Once installed in a stack of sheets, the asymmetric self-piercing rivet prevents relative sheet rotation of the sheets relative to the axis because of rotational interference caused by the external axial asymmetry of the hollow shell.

Abstract: The present invention is a self-piercing rivet wherein the hollow shell has an external spiraling, wherein the spiraling is with respect to the axis of rotation of the hollow shell. Once installed in a stack of sheets, the spiraling prevents the riveted sheets from mutually separating and the rivet loosening with respect to the sheets.

Abstract: A first metal member is contacted with a second metal member. A metal fastener is provided including a core and a cladding disposed upon the core. The fastener is driven through the first member and into the second member, inducing friction between the fastener, the first member and the second member for at least locally melting portions of the cladding, the first member and the second member to form a flowable material that solidifies and metallurgically bonds the fastener to the first member and the second member for attaching the members together.

Abstract: A friction stir rivet is rotated and driven through a first fusible workpiece into an engaged second fusible workpiece, causing local portions of the first and second workpieces to plasticize. A slideable cap contacts the exposed surface of the first workpiece shortly after the process begins. The cap acts as a retaining element limiting plasticized material from escaping during the process. As the rivet is further driven into the members the cap slides up the rivet and actuates an angled stirring member to increase the stir radius around the body of the rivet. Once the rivet is driven into the first and second workpieces, rotation is stopped and the plasticized material cools and hardens around the rivet, creating a weld joining the workpieces and encompassing the rivet, which provides additional mechanical strength.

Abstract: A first metal member is contacted with a second metal member. A metal fastener is provided including a top radially enlarged portion, a bottom radially enlarged portion and a shank portion intermediate the thicker portions for forming a circumferential groove about the axis and fastener. The fastener is driven through the first member and into the second member, inducing friction between the fastener, the first member and the second member for at least locally melting portions of the first member and the second member to form a flowable material that flows into the circumferential groove of the fastener and solidifies.

Abstract: A method of attaching metal members, including placing the metal members in contact with each other and fastening them with a metal fastener having a central axis wherein the metal fastener includes an elongated portion having a substantially constant cross-sectional area at any cross-section taken along a length of the elongated portion perpendicular to the axis of the fastener and includes a topographically varying outer surface. The fastener is driven through the metal sheet and into the metal substrate during rotation of the fastener thereby inducing friction between the fastener, the sheet and the substrate for locally melting the members to form a flowable material that solidifies for attaching the members, the flowable material and the fastener together.

Abstract: A pneumatic spring having a piston and rod assembly operatively mounted in a gas-charged cylinder tube which expands when an associated closure such as a lift gate of a vehicle is released from its locked position. The force of the pneumatic spring assists the swinging movement of the lift gate on its hinges relative to the bodywork of the vehicle. As the lift gate opens, the pneumatic spring expands with the piston rod telescoping outwardly of the cylinder tube, which operates to pull a dust tube normally surrounding the cylinder tube. This around the tube until a stop ring secured to the end of the dust engages a stop collar operatively mounted on the cylinder tube. This positively limits the expansion of the gas spring and thereby establishes the open position of the lift gate.

Abstract: A side-mount bracket system for locking the sensor position with respect to a side-mount bracket once the air gap is first established by the gauging layer method, wherein the sensor may be removed and then reinstalled without use of any position setting procedure, yet the air gap is automatically precisely reset to its original value. The side-mount bracket system according to the present invention includes a washer and a side-mount bracket having an elongated slot, wherein as the washer is brought into the slot, facial interaction therebetween, eg., teeth inscribing a smooth surface, causes the washer to be positionally fixed with respect to the bracket. Alternatively, the washer may be slidably trapped onto the bracket at the slot, and a tapered bolt having a varying cross-section which causes expansion of the washer as it is threaded home, thereby affixing the washer positionally with respect to the bracket.

Abstract: A two-component bracket and drive washer combination which provides secure holding of a magnetic sensor while automatically setting an optimal air gap, wherein operation is very quick, easy and reliable and wherein the air gap setting is precisely repeated each time a magnetic sensor is replaced or re-installed. A main bracket component has an aperture and a drive wall at one end of the aperture. A sensor body is connected to the main bracket component and is allowed to touch a reluctor. A reaction bracket has a reaction wall in the aperture opposite the drive wall and is restrained from moving. A drive washer is provided with teeth having a pitch whereby as the washer is pressed between the drive and reaction walls along a transverse axis, the main bracket component is forced to move along a longitudinal axis, thereby moving the sensor body in relation to the reluctor an amount precisely equal to a desired air gap.

Abstract: An improved connector establishes an electrical connection between an external conductor and a planar conductor of an insulated flexible circuit board, utilizing an automatically deployed cutting mechanism for removing insulative material overlying the flexible circuit conductor when the electrical connection is established. The connector includes an insulative housing having a slot for receiving an interconnect stub of the flexible circuit, and a compliantly mounted cutting mechanism electrically coupled to the external conductor. The cutting mechanism extends partially into the slot, and is compliantly displaced away from the slot as the interconnect stub is inserted into the slot. When the interconnect stub is partially extracted from the slot, the cutting mechanism forcibly engages the stub, removing a portion of the overlying insulative material, and electrically contacting the flexible circuit conductor to establish the electrical connection between it and the external conductor.
