  • Patent number: 10697491
    Abstract: Exemplary embodiments provides a camera, having a first camera sub-assembly, a hub coupled to the first camera sub-assembly, a second camera sub-assembly coupled to the hub and rotatable relative thereto and a third camera sub-assembly coupled to the hub and rotatable relative thereto. The third camera sub-assembly can be in electrical communication with the first camera sub-assembly and/or the second camera sub-assembly via the hub. The hub can include a slot to guide electrical cable(s). Net torque acting on the camera can be zero such that one of the first rotational coupling or the second rotational coupling when rotated to a new position via an applied torque remains in the new position when the applied torque is released.

  • Patent number: 7722361
    Abstract: An improved test socket for use in testing integrated circuits. The test socket includes a housing having one or more slots formed therein. Contacts can be received within respective slots and maintained therein with rear ends of the contacts in engagement with traces on a load board. Mounting is accomplished by means of a pair of elastomers, and the elastomers maintain each contact such that, when the front end of a contact is engaged by the lead or pad of the device to be tested and urged into its corresponding slot, an arcuate surface at a rear end of each contact rolls across its corresponding trace with virtually no translational or rotational sliding.

  • Patent number: 7639026
    Abstract: A contact for use in a test set which can be mounted to a load board of a tester apparatus. The contact, which serves to electrically connect at least one lead of a device being tested with a corresponding metallic trace on the load board, has a first end defining multiple contact points. As the contact is rotated about an axis generally perpendicular to a plane defined by the contact, successive contact points are sequentially engaged by a lead of the device being tested.

  • Patent number: 7567075
    Abstract: An actuator device applies force to an integrated circuit package to enable temporary contact between a plurality of contacts on the integrated circuit package and to a set of test contacts carried on a contactor support. A cover is hinged at one side, and rotates to position that allows an actuator element to apply force through a lead backer to the integrated circuit package or its leads, pressing the integrated circuit contacts against the test contacts. A latch opposite to the hinge holds the cover in the closed position. An interlock mechanism may be provided to prevent operating the latch unless the actuator element has withdrawn the lead backer from the integrated circuit or its leads, thereby preventing damage to components.

  • Patent number: 7202657
    Abstract: An actuator for pressing a plurality of circuit contacts carried on a microcircuit package against a plurality of test contacts has a frame having a top surface and a bottom surface facing away from the top surface. The frame has first and second end slots each intersecting the top surface at opposite ends thereof. A loader foot is carried by the frame's bottom surface for applying force to a microcircuit. First and second latch elements, each respectively mounted within the frame's first and second end slots are each shiftable between a latched position and an unlatched position within the frame's first and second slots, each said latch element when in the latched position for gripping an edge of an alignment plate and when in the unlatched position for releasing the alignment plate. An actuator element mounted on the frame's top surface receives manual force and converts the received manual force to force applied to the latch elements to shift the latch elements between the latched and unlatched positions.

  • Patent number: 6789876
    Abstract: An improved, large-format digital inkjet print engine that includes a group of co-operating print engine subassemblies that embody various novel elements that both discreetly and cumulatively advance the current art. The group of subassemblies and sensors cooperate to produce high quality graphic images using a plurality of different colors of ink and different types of print media at speeds several times faster than similar conventional inkjet printers. In addition, the use of cooperating elements permit the manufacture of complex, large-format digital color inkjet print engines that are less expensive to fabricated, operated, and serviced. The present invention finds use in large-format digital color printing and imaging, where successful repeatable printing requires precise placement of droplets of ink, toner or other marking material on a print medium such as paper, vinyl, film, or similar substrate.

  • Patent number: 5540213
    Abstract: A kerosene heater (1) having a pump assembly (106) which includes a piston (113) having a hollow bore (121) through which fuel (98) is routed to the hollow shaft of a fuel atomizer (27). The piston (113) is operated by a cam (117) machined into the shaft (114) of the heater motor (22). Mounted on the motor shaft (114) between the atomizer (27) and the pump assembly (106) is a novel fan (26) combining both low pitched outer blade portions (143) and high pitched vanes (146) near the hub (136) of the fan (26). The air flow near the periphery of the fan tends to be axial while the flow near the hub (136) tends to be turbulent and of lower velocity. A series of rear heads (32,33) downstream of the atomizer (27) tends to separate cooling and combustion air while preheating a portion of the air in the region of the atomizer (27).
