  • Publication number: 20020038741
    Abstract: The present invention is a bracket for constructing a sawhorse. The sawhorse constructed with the brackets allows the legs of the sawhorse to fold into a compact unit by having the legs interleave when folded. The legs pivot about a plane that is canted to allow each leg to rotate without interfering with any other leg. The length of the legs are not restricted in any fashion. The legs may also be locked in both the extended, or service position as well as the closed position. The bracket may be constructed of as few as two unique parts, and a pair may be nested together for compact shipping, storage, and display on a store shelf.

  • Patent number: 6323903
    Abstract: A mount for directional devices such as cameras, optical devices or laser devices, providing independent orthogonal adjustment of panning alignment of such devices in a horizontal plane in combination with independent adjustment of rotation alignment of such devices about a vertical axis parallel to the optical axis. In a preferred embodiment, a CCD camera is aligned over a Liquid Crystal Display under test. Threaded adjustment screws angularly separate opposing plates disposed along each of x-, y- and z-axes. This angular separation generates a moment about the axis of rotation, causing a corresponding shift in the camera's alignment. Structure is also provided to compensate for differential thermal behavior of opposing plates. The inventive mount is advantageously designed to be reversible so that left-handed and right-handed embodiments can be nested to facilitate a multi-camera deployment.

  • Patent number: 6262571
    Abstract: An adjustable electrical connector having a rigid or spring-loaded conductive element and a cable coupled to the conductive element. The adjustable electrical connector provides electrical connection to a device under test held in place on a test fixture nest, transferring an electrical signal such as a power source from the cable to the device under test through the conductive element. The adjustable electrical connector may be secured to the test fixture nest in a number of different positions to easily accommodate different types of devices under test.

  • Patent number: 6097334
    Abstract: The inventive connection mechanism uses a tongue and groove connection in combination with a RF gasket. Fixture panels are constructed by placing the tongue of one panel into the groove of another panel. The gasket is pre-positioned in the groove, such that the tongue compresses the gasket to the manufacture's specified compression thickness. The panels can then be secured using fasteners. RF fixtures constructed with such connection mechanisms can be rapidly assembled. Moreover, the RF fixtures can be rapidly taken apart to allow for maintenance of the internal elements of the fixture. The use of the tongue and groove connection with the RF gasket provides an RF sealed connection. Thus, the fixture is not subject to interference from undesirable external RF signals.

  • Patent number: 6067866
    Abstract: The inventive fixture adapter has installed pneumatic actuators. Pneumatic connections for the actuators are made during installation of the adapter in the fixture. Thus, testing of a device can begin before the drawer is closed, and be completed while the drawer is being opened, thus saving cycle time. The adapter is removably connected to the drawer mechanism of the fixture, and thus can quickly and reliably be changed for a different adapter. All of the customization required for a particular device can be confined to the adapter, and thus the reset of the fixture can be made generic.

  • Patent number: 6047599
    Abstract: The inventive mechanism has an RF door separate from the drawer of an automatic testing machine fixture. The door is either attached to an adapter which holds a device that is to be tested, or attached to a peripheral portion of the fixture. Consequently, changing the adapter is simplified, and the likelihood of damage to the adapter is lowered. When the drawer is in a closed position, the door meshes with the fixture to provide an RF sealed area for RF testing a device.

  • Patent number: 6037788
    Abstract: The inventive mass interface or docking station comprises several resource connections that are located in a predetermined arrangement. These connections couple with connections arranged in complementary manner on the test fixture. The resource connections provide the various electrical, power, RF, and pneumatic resources required to test the production devices. The predetermined arrangement of connections allows fixtures to be quickly changed, as all connections can be simultaneously coupled and de-coupled. Thus, the docking station interface on the test fixture is standardized, and the test machine interface on the inventive docking station is customized to the test machine.

  • Patent number: 5540542
    Abstract: A tool that loads magnetic heads onto the disk of a hard disk drive. The tool has a first arm which has an alignment block and a plurality of fingers. The first arm cooperates with a second arm which has an alignment slot and a plurality of second fingers. The arms are coupled to an actuator which moves the arms in opposite directions to separate the first fingers from the second fingers. Movement of the arms also causes a first alignment surface of the alignment block to engage a second alignment surface of the alignment slot. The alignment surfaces are essentially parallel with the fingers and insure that the fingers translate relative to each other without any relative rotational movement.

  • Patent number: 5465476
    Abstract: An assembly station that loads heads onto a disk of a hard disk drive and allows a crash stop to be mounted to the drive unit. The assembly station includes a load arm positioner which can slide along an annular ring. Mounted to the load arm positioner is a scissor assembly tool which can engage and separate the actuator arms. The load arm positioner can be moved about the annular ring so that the scissors engage the actuator arms and load the heads onto the disk. The pivot point of the actuator arms is located at the center of the annular ring so that there is no relative movement between the scissor tool and the actuator arms when the heads are loaded onto the disk.
