  • Publication number: 20060052714
    Abstract: A method of vascular testing includes inflating a cuff at a vascular location, controllably deflating the cuff, producing a pressure waveform while deflating the cuff, and producing an output representing a pressure at which blood flow returns, while deflating the cuff, based upon analysis of the pressure waveform. Further, a testing system for measuring vascular pressures according to the present invention includes a pressure applicator, a pressure sensor, and a diagnostic test unit. The pressure applicator is positionable along exterior portions of a human body for dynamically applying pressure to a desired vascular location. The pressure sensor is capable of detecting oscillations in a pressure at the pressure applicator.

  • Publication number: 20060052712
    Abstract: A vascular sensing system includes blood flow restricting means, a sensor, and means for producing an output representing a return of blood flow after the blood vessel has been temporarily collapsed by the blood flow restricting means. The blood flow restricting means is capable of placement on a human toe having a blood vessel, and is capable of manipulating the blood vessel. The sensor is operably connected to the blood flow restricting means and is physically spaced from the toe. Further, a method of vascular sensing includes taking pressure measurements with an pressure cuff positioned on a toe, and conducting a waveform analysis of the pressure measurements to determine a return of blood flow pressure.

  • Publication number: 20050161140
    Abstract: A pneumatic tire has a carcass structure extending through a pair of opposing bead portions and an inner liner located inward of the carcass structure, each bead portion comprising a bead core about which is wrapped the carcass structure and a toeguard. Each bead portion has a bead toe, a bead base, and a bead heel, the bead base extending between the bead toe and the bead heel. The bead heel has a profile corresponding to a sector of an ellipse or approximates a sector of an ellipse by having a dual radius structure. The bead base may have a dual taper configuration. The bead core may be substantially centered in the bead portion, as determined by the material thickness at three locations about the bead core.

  • Patent number: 6199124
    Abstract: In accordance with principles of the invention, there is provided an arbitration system for multiple requesters of a shared data transfer resource, such as a system bus or a peripheral bus. The disclosed system arbitrates among multiple classes of requesters which are divided into multiple levels of a request hierarchy. In the example embodiment, the multiple requesters include logic for processing received data from the network, logic for processing data to be transmitted onto the network, logic for moving transmit and receive descriptors between the host memory and the adapter, logic for reporting status from the adapter to the host, and logic for generating an error and maintenance status update from the adapter to the host. The new system ensures fairness between transmit and receive processes, that FIFOs associated with transmit queues are not underrun, and further than notification of non-error and maintenance status changes are processed with minimal latency.

  • Patent number: 5825453
    Abstract: An eyeglass nosepiece is formed on a housing that defines two translational paths for guiding two independently travelling nosepads. The nosepads are free to travel between the top and bottom of each path, opposed only by resilient biasing means which absorb downward shock to the nosepiece and urge the nosepads upward and inward to grip the wearer's nose securely.

  • Patent number: 5745952
    Abstract: A hermaphroditic ball and socket joint permits a ball to rotate freely within a socket within constrained bounds. The socket resides within a housing that has an exterior surface having a rotational axis of symmetry passing through the center of the socket. A channel connects the socket to the exterior surface. The ball extends from a member having a collar which partially enshrouds the ball and which has an inside surface that is substantially identical to the exterior surface of the socket housing and which has an axis of rotational symmetry passing through the center of the ball. The free rotation of the ball in the socket is constrained by the restricted movement of the member through the channel and the restricted rotation of the collar around the exterior surface of the housing.

  • Patent number: 5649110
    Abstract: A system for controlling the transmission of cells from a network node over multiple virtual circuit is disclosed. The disclosed system performs traffic shaping for all virtual circuits connected with the network node. The system includes a virtual circuit table with one or more entries. Each virtual circuit table entry corresponds to a virtual circuit established with the network node. Each virtual circuit table further includes one or more Cell Rate Accumulator fields and a Time Stamp field. The system includes a schedule table having one or more entries. Each schedule table entry further includes one or more Cell Rate Accumulator fields and corresponding predetermined value fields. A schedule table loading process determines a virtual circuit on which a packet is to be transmitted, and then calculates a time elapsed since a last previous write of a virtual circuit table entry corresponding with that virtual circuit.

  • Patent number: 5639687
    Abstract: Reflective notching of a photoresist pattern (20), generated over reflective materials on a semiconductor substrate (12), is minimized by using an anti-reflective layer (20) of silicon-rich silicon nitride. The layer of silicon-rich silicon nitride is formed over the reflective materials and a layer of photoresist is then formed over the silicon-rich silicon nitride. The photoresist layer is then photolithographically patterned to form an integrated circuit pattern (20). The silicon-rich silicon nitride layer has an absorptive index of greater than 0.25, which allows it to be used as an anti-reflective layer with photolithographic patterning systems having ultraviolet and deep ultraviolet exposure wavelengths.
