  • Patent number: 11493535
    Abstract: A reduced pin count (RPC) device includes an electrical circuitry in a package with uniformly distributed leads, a subset of the leads being electrically disconnected form the circuitry. A contactor pin block with sockets corresponding to the uniformly distributed leads has the sockets corresponding to the leads with electrical connections filled with test pins suitable for contacting respective leads, and the sockets corresponding to the electrically disconnected leads voided of test pins. Dummy plugs are inserted into the voided sockets to block the sockets and prevent accidental insertions of test pins.

  • Patent number: 9673539
    Abstract: A spring biased contact pin assembly includes a barrel member having a barrel wall defining an elongate internal cavity with a lower end and an upper end. The assembly also includes a lower plunger member reciprocally mounted in the internal cavity proximate the lower end of the internal cavity. A spring member is positioned in the internal cavity between the lower plunger member and the upper end of the internal cavity. A high electrical resistance spacer member is positioned in the internal cavity in contact with the lower plunger member and the spring member. Spring force exerted through the spacer member urges the lower plunger member into electrical contact with the barrel wall. A method of transmitting electricity through an electrical contact assembly includes urging a plunger member against the wall of a barrel member in which it is reciprocally mounted with a high electrical resistance member.

  • Publication number: 20150183432
    Abstract: A system for speed control of a vehicle (12) comprising a plurality of zones (16) defined within an area (12). Pairs of markings (18) are provided on surfaces in the area (12) on opposite sides of boundaries (17) of the zones (16). A sensor device (22) is provided on vehicles (12) travelling in the area (12) to obtain images from the surface adjacent the vehicle (12) and to detect the presence of the markings (18) within the image. A speed controller (26) is provided on the vehicle (12) to set a maximum vehicle speed based on information received from the sensor device (22). The sensor device (22) is configured such that on detection of the second marking (18) within the image within a predetermined time period of detection of the first marking (18), the sensor device (22) communicates with the speed controller (26) to set the maximum speed limit to that associated with the second marking (18) and on detection of no marking within the image, the maximum vehicle speed remains unchanged.

  • Patent number: 6477703
    Abstract: A patch selection tool providing a method and apparatus for identifying software patches for installation on a computer system in which current versions of software applications installed on the computer system are identified as well as currently installed patches, products, and versions. An initial list of recommended patches is generated based on the combination of the installed products and the validated list of datasheet selected products, a final list is created by modifying the initial list to remove bad or outdated patches.
