  • Probe for combined signals
    Patent number: 7417446
    Abstract: A direct current and a modulation signal are simultaneously applied to contact pads on a device under test, such as a laser diode, with a probe that reduces signal distortion and power dissipation by transmitting a modulated signal through an impedance matching resistor and transmitting of a direct current over a second signal path that avoids the impedance matching resistor.

  • Membrane probing system
    Patent number: 7400155
    Abstract: A substrate, preferably constructed of a ductile material and a tool having the desired shape of the resulting device for contacting contact pads on a test device is brought into contact with the substrate. The tool is preferably constructed of a material that is harder than the substrate so that a depression can be readily made therein. A dielectric (insulative) layer, that is preferably patterned, is supported by the substrate. A conductive material is located within the depressions and then preferably lapped to remove excess from the top surface of the dielectric layer and to provide a flat overall surface. A trace is patterned on the dielectric layer and the conductive material. A polyimide layer is then preferably patterned over the entire surface. The substrate is then removed by any suitable process.

  • Base plate for magnetic attachment assembly
    Patent number: 7377474
    Abstract: Described is a removable assembly for use on a fixed surface. The assembly includes a post having a base (42) and an attachment assembly (8). The attachment assembly includes a base plate (10) and a magnet assembly (12), both capable of carrying a magnetic current. The magnet assembly includes a housing (20) and a magnet (22) disposed within the housing. To use, the magnet assembly is placed adjacent the base plate, the magnetic forces attracting and holding them together. The magnet is positioned apart from the base plate while the housing contacts the base plate to form the magnet circuit. An attachment plate (30) is connected to the housing upper wall adjacent its outer surface. The attachment plate includes one or more outwardly projecting attachment bolts (26). As assembled, the bolts engage corresponding openings (48) in the post base (42).

  • Adjustable pipe repair clamp installation tool
    Patent number: 7364202
    Abstract: A manually operated tool engages and draws towards one another opposed spaced flanges of a repair clamp disposed about a leaking pipe for moving the clamp into position and securely maintaining the clamp on the pipe over the leak allowing plural nut and bolt combinations on the clamp to be tightened in sealing off the leak. A movable handle has attached thereto first and second pivoting arms adapted for respectively engaging a slot within the clamp's first edge flange and the outer edge of the clamp's second opposed edge flange when the handle is in a first non-use position. Moving the handle to a second use position urges the clamp's edge flanges toward one another drawing the clamp securely about the pipe, allowing the clamp's nut and bolt combinations to be tightened. The tool is adjustable for use with a wide range of clamp sizes and pipe diameters.
