Abstract: A method of operating a solid-state relay device includes receiving an input signal at an input of the solid-state relay device and coupling the input signal to transmit circuitry disposed on a transmit die. In response to receiving the input signal the transmit circuitry generates a corresponding time varying electrical voltage that is coupled from the transmit circuitry to a transmit coil and a receive coil is induced to generate an intermediate signal. A switch drive signal is generated which transitions a solid-state switch from an off state to an on state, wherein the switch drive signal corresponds to the input signal and wherein the drive signal is electrically isolated from the input signal.

Abstract: A method of operating a signal isolation device includes receiving an input signal at an input of a transmit die and in response, generating a corresponding time varying electrical voltage at a transmitter output of the transmit die. The time varying electrical voltage is coupled to a transmit coil disposed within a receiver die. A receive coil is induced to generate an intermediate signal in response to the coupling of the time varying electrical voltage to the transmit coil, wherein the intermediate signal corresponds to the input signal. The intermediate signal is coupled to receiver circuitry disposed within the receiver die. Electromagnetic noise generated by the receive coil is shielded from the receiver circuitry via a shield positioned between the receive coil and the receiver circuitry.

Abstract: A surgical method and implant for directing and securing a replacement ligament into the femur or tibia of the knee. A transverse tunnel may be formed in the femur approximately perpendicular to a femoral tunnel. A flexible strand passing through the transverse tunnel may be used to draw the replacement ligament into the femoral tunnel. The implant may then be placed into the transverse tunnel and through the replacement ligament to secure the replacement ligament in place. The implant may include an eyelet to receive the flexible strand and a tapered portion forming a shoulder to prevent the implant from being inserted too far into the transverse tunnel. The implant may also have a multi-angular configured portion to secure the implant within the transverse tunnel through an interference fit.

Abstract: Instruments and method for the arthroscopy arthroplasty of a knee joint, including instruments and method for the use of the instruments in the resection of tibial and femoral surfaces and the implantation of tibial and femoral components. In resecting the femur, a femoral cutting mill is attached to the tibial surface with the knee in a flexed position. With the cutting mill activated, the knee is extended causing the cutting surface of the femoral cutting mill to engage the femoral surface and form a trough in the femoral surface for receipt of the femoral component. A network of channels formed within the prosthetic components is used for the delivery of bone cement to the component bone interface.

Abstract: Novel storage area networks (SANs) and methods of operation thereof utilize a plurality of hosts coupled via an interconnect with one or more storage units. A manager device, process or other functionality in communication with a plurality of agent processes, devices or other functionality, each of which is associated with a host. The agents identify attributes of (i) their associated hosts, (ii) interconnect to which that host is coupled, and/or (iii) storage units to which that host is coupled via the interconnect. The manager responds to these attributes identified by the agents to manage the SAN. The manager can be implemented on a first digital data processor and the hosts on further digital data processors. These digital data processors can be coupled via a first network, e.g., an IP or other network, to support communications between the manager and the agents. A second network, e.g.

Abstract: A method of soft tissue graft fixation to bone. A tunnel may be formed in a bone and a bio-compatible material may be placed in the tunnel in a liquid state using an insertion device. The soft tissue grafts may also be placed in the tunnel using the insertion device. The insertion device may serve as an internal mold to form a chamber for receiving a fastener. The liquid bio-compatible material may solidify around the insertion device, and the insertion device may be removed. Final fixation may be accomplished by inserting a fastener in the hardened bio-compatible material to apply a compressive force to compress the graft against the bone.

Abstract: A knee joint resurfacing implant is disclosed. The knee joint resurfacing implant may include femoral implant and tibial implant components. The femoral implant components may be attached to the femur using screws or other fixation devices. The femoral implant component may be configured to share loads between cortical and cancellous bone material. The tibial implant components are formed in modular portions which may be assembled within the knee joint and may be free-floating or fixed to the tibial surface. The implant components are of such a size and configuration that the components may be placed into the knee joint through an external skin incisions that measure 3 cm or less. Accordingly, the size of skin incisions required for implantation may be reduced when compared to incisions which are now commonly used.
