Abstract:
A lightweight radio/CD player for vehicular application includes a case and frontal interface formed of polymer based material molded to provide details to accept audio devices and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips.
Abstract:
A lightweight radio/CD player for vehicular application is virtually “fastenerless” and includes a case and frontal interface formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RFI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting “slide lock” and “snap lock” self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.
Abstract:
The present invention provides a method and a system for determining whether a target component of an electronic assembly is assembled correctly. The method of the present invention involves correlating the view of a test electronic assembly with both a positive control image and a negative control image. The positive control image is an image of an electronic assembly that has been assembled properly, whereas the negative control image is an image of an electronic assembly that has been assembled improperly. If the correlation between the test image and the positive control image is greater than the correlation between the test image and the negative control image, the test assembly is assembled properly. On the other hand, if the correlation between the test image and the negative control image is greater than the correlation between the test image and the positive control image, the test assembly is assembled improperly.
Abstract:
A magnetic device for attracting and retaining a fastener which has a bit, a generally ring-shaped keeper having a bottom surface, at least some portion of which bottom surface is magnetized, at least one pair of magnets, each pair of magnets having two magnets with alternating poles, adjacent to the magnetic bottom surface of the keeper and arranged around the bit such that an even number of magnets with alternating poles is arranged around the bit, and a non-magnetic holder that secures the keeper and the magnets and surrounds the bit. The magnets provide magnetic flux to the keeper and the fastener. Each pair of adjacent magnets provides a closed magnetic flux path through a first magnet of the pair, the keeper, a second magnet of the pair, and the fastener. The location of the magnetic device along the bit may be adjustable or fixed.

Abstract:
A motion mechanism for achieving motion in two directions that are at right angles to each other includes two linear actuator assemblies arranged parallel to each other, a carriage assembly mounted on each of the linear actuator assemblies, and a head slidably linked on opposite sides thereof to the carriage assemblies via slide assemblies that have slide members that are linearly movable with respect to each other along equal but opposite angles with respect to the direction of movement of the carriages.
