  • Patent number: 9097757
    Abstract: A 2×2 switching element that includes first and second relays each having a first terminal, a second terminal and a third terminal, wherein the first and second relays each operate between a first state to connect the first terminal to the second terminal and a second state to connect the first terminal to the third terminal. The second terminals and third terminals, respectively, of the first and second relays are coupled to one another. The 2×2 switching element is selectively operable between: a first switching state where the first relay is operated in the first state and the second relay is operated in the second state, and a second switching state where the first relay is operated in the second state and the second relay is operated in the second state.

  • Patent number: 8704408
    Abstract: A method that includes identifying a desired signal connectivity through a switch matrix, where the switch matrix includes a plurality of switching elements, and where the switching elements are selectively operable in a plurality of states to provide a plurality of signal paths for routing signals through the switch matrix. The method also includes identifying a sorting network model that corresponds to a topology of the switch matrix, applying a sorting algorithm to the sorting network model, and determining, based on the results of applying the sorting algorithm, operational states of the plurality of switching elements to provide signal paths corresponding to the desired signal connectivity.

  • Patent number: 8062295
    Abstract: An improved method for attaching soft tissue to bone by passing a suture through an opening in the bone, e.g., a transosseous tunnel, and affixing the soft tissue with the suture. The improvement, for preventing the suture from migrating through the bone at the end of the opening, includes placing a eyelet into an end of the bone opening and passing the suture through the eyelet, as well as through the opening in the bone, in order to affix the soft tissue to the bone with the suture.

  • Patent number: 6800093
    Abstract: A spinal implant replaces excised tissue removed during spine surgery. This implant includes fasteners which firmly attach it to vertebrae adjacent to excised tissue so as to transmit tension and torsional loads to and from those vertebrae. The body of the implant has through cavities into which bone growth material is placed during surgery. The body of the implant also has a finite modulus of elasticity in compression so as to share compressive loads with emplaced bone growth material and with new bony growth facilitated by the emplaced material and the load sharing.

  • Patent number: 6524316
    Abstract: A bone fastener including an expandable member having an axial channel and an elongated element insertable into the axial channel is described. The expandable member is configured to be insertible into a bore drilled in bone. The distal end of the expandable member also may include a structure for axially releasing the expandable member from an emplacement device that places the expandable member into a bone opening. In one embodiment, the structure for axially releasing includes a frangible membrane capable of being severed from the expandable member during emplacement of the expandable member in a bone opening. A rivet for coupling an object to bone for use with an expandable member is also described. The distal end of the elongated element is shaped into a radially projecting portion adapted for engagement with a washer that contacts the object to be coupled. The washer, having upper and lower surfaces and a bore defined between the surfaces, is disposed around a portion of the shaft.

  • Patent number: 6507392
    Abstract: One version of the invention relates to a laser detection system that includes a ball lens and a plurality of fiber optic bundles placed adjacent the ball lens so that incoming light rays are focused onto the bundles by the ball lens. In one particular version of the invention, a ball lens is one that can provide an almost infinite number of “principal” axes for off-axis light. Each fiber optic bundle is aimed in a different direction from each other bundle so that each bundle will have a different FOV even though the same ball lens is used to focus the incoming light rays.
