  • Foot orthosis support device method and apparatus
    Publication number: 20070191748
    Abstract: A corrective device to be worn on a human foot having a misalignment and positioned inside of footwear. The device having an inner shell having a first material composition and flexibility, and shaped to accommodate receiving therein and supportingly couple with the foot, and an outer shell having a second material composition and flexibility, the second material composition and flexibility being substantially the same as the first flexibility, the outer shell shaped to accommodate receiving therein the inner shell, supportingly couple with the inner shell and allow positioning into the footwear. At least a sufficient portion of a pressure is distributed by the outer shell and the inner shell over a desired area of the foot to provide an amount of correction to the misalignment while allowing the human to wear the inner shell inside of the outer shell inside of the footwear.

  • Casing spacer with joint restraint
    Patent number: 7225837
    Abstract: An integrated casing spacer and joint restraint unit is attached to each of a pair of pipe sections adjacent to an end-to-end connection of the pipe sections by means of first and second spacer/retainer ring members. Disposed on the outer periphery of each ring member in a spaced manner are plural risers each having a respective runner disposed on its outer end for engaging an inner surface of an outer casing and maintaining fixed spacing between the inner pipe sections and the outer casing. Plural paired risers, with one riser disposed on each ring member, are aligned with one another along the axis of the connected pipe sections and are each adapted for secure connection to a respective connecting rod for securely coupling the two ring members together and restraining relative movement between the two pipe sections.

  • Probe holder for testing of a test device
    Patent number: 7221174
    Abstract: A system for low-current testing of a test device includes a probing device for probing a probing site on the test device. The probing device includes a dielectric substrate having first and second sides, an elongate conductive path on the first side of the substrate, an elongate probing element connected to the elongate conductive path so as to extend in a cantilevered manner beyond the substrate, and a conductive area on the second side of the substrate. The probe housing is matingly detachably engageable with the probing device.

  • Probe for combined signals
    Patent number: 7205784
    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.

  • Magnetic assembly for reversibly securing a post
    Patent number: 7188821
    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).

  • System for evaluating probing networks
    Patent number: 7164279
    Abstract: An interconnect assembly for evaluating a probe measurement network includes a base, respective inner and outer probing areas in mutually coplanar relationship on the upper face of the base, a reference junction, and a high-frequency transmission structure connecting the probing areas and the reference junction so that high-frequency signals can be uniformly transferred therebetween. A preferred method for evaluating the signal channels of the network includes connecting a reference unit to the reference junction and successively positioning each device-probing end that corresponds to a signal channel of interest on the inner probing area.
