  • Patent number: 7283627
    Abstract: An apparatus for enabling hands free activation of a telephone includes a base, a telephone unit and a mechanical actuator via which a user can activate the telephone unit without using his or her hands. The telephone unit has an ON/OFF button that can be switched between an ON state and an OFF state. The mechanical actuator is operable by a user's chin and is mountable to the base. The actuator is disposed above the telephone unit and aligned with the ON/OFF switch so that pressing down on the actuator switches the ON/OFF button between its two states. This telephone unit, when used in conjunction with a voice recognition dialing service allows the user to place calls without the use of his or her hands. The telephone unit is coupled to the base and is activated by activation of the ON/OFF switch via the user's chin or other body part.

  • Patent number: 7076136
    Abstract: A method and apparatus is provided for attaching an optical fiber to a waveguide formed on a planar lightguide circuit (PLC). The method begins by securing at least one joint element to a first surface of the PLC. The joint element has a beveled surface such that a gap is formed between the joint element and the first surface of the PLC. The gap is adjacent to an end face of the waveguide. The waveguide end face extends in a plane that includes a transverse surface of the joint element to define therewith a first mating surface. The optical fiber is secured to a support member such that an end face of the optical fiber extends in a plane that includes a transverse surface of the support member to define a second mating surface therewith. The waveguide end face is aligned with the optical fiber end face.

  • Patent number: 7051170
    Abstract: A method and system for decoding a transport stream are disclosed. In one embodiment, the method includes receiving a system information table in the transport stream, reading an activation time from the system information table, storing the table in a memory without activating values contained in the system information table, determining when the activation time is reached, and activating the values contained in the system information table when the activation time is reached. An advantage of the present invention is that the program and system information tables can be transmitted less frequently and still allow the receiver to execute the acquired “next” tables in a timely manner, once the tables have been received for the first time and their activation times have arrived. Another advantage of the present invention is its backward compatibility with the existing protocol formats, because the present invention requires no syntactic modification to the existing table formats.

  • Patent number: 7001378
    Abstract: An enhanced method and device are provided to treat atrial fibrillation or inhibit or reduce restenosis following angioplasty or stent placement. A balloon-tipped catheter is disposed in the area treated or opened through balloon angioplasty immediately following angioplasty. The balloon, which can have a dual balloon structure, may be delivered through a guiding catheter and over a guidewire already in place. A fluid such as a perfluorocarbon flows into the balloon to freeze the tissue adjacent the balloon, this cooling being associated with reduction of restenosis. A similar catheter may be used to reduce atrial fibrillation by inserting and inflating the balloon such that an exterior surface of the balloon contacts at least a partial circumference of the portion of the pulmonary vein adjacent the left atrium. In another embodiment, blood perfusion is performed simultaneously.

  • Patent number: 6985443
    Abstract: A method is provided for alleviating congestion in a computer network. The network includes a plurality of nodes interconnected by communication links, which communicate in accordance with at least an optical layer protocol and a second protocol layer. The method begins by receiving a signal in accordance with the optical layer protocol and determining if local forwarding capacity is available to forward the signal in accordance with the second protocol layer. If the local forwarding capacity is unavailable, the method continues by forwarding the signal in accordance with the optical layer protocol to another node having excess capacity so that the other node can forward the signal in accordance with the second protocol layer.

  • Patent number: 6982216
    Abstract: A method is provided for fabricating a MOSFET device. The method begins by forming a semiconductor device having a substrate on which a gate conductor having sidewalls separates a source region and a drain region. An oxide layer is formed over the gate sidewalls and a portion of the substrate. Ions of a first conductivity are implanted into the source and the drain regions to define source and drain extensions that respectively extend in part under the gate conductor. A nitride layer is formed over the oxide layer that extends over the portion of the substrate. An angled ion implant is performed during which the gate conductor shields a portion of the nitride layer over at least a portion of the drain region from damage by the angled ion implant. The angled ion implant selectively damages portions of the nitride layer in which ions are implanted to form damaged portions of the nitride layer.

  • Patent number: 6974463
    Abstract: Embodiments of the invention provide a system for temperature control of the human body. The system includes an indwelling catheter with a tip-mounted heat transfer element. The catheter is fluidically coupled to a console that provides a heated or cooled heat transfer working fluid to exchange heat with the heat transfer element, thereby heating or cooling blood. The heated or cooled blood then heats or cools the patient's body or a selected portion thereof. In particular, methods and devices, including software, are provided for administering cooling or rewarming and controlling the same based on a projected control temperature measured by a temperature sensor within the catheter.

  • Patent number: 6970628
    Abstract: A method and apparatus is provided for attaching a bulk element processing an optical beam to a PLC and optically aligning the bulk element with an optical element formed on the PLC. The method begins by securing the bulk element to a first side of a substrate. A first side of a flexure element is secured to the first side of the substrate. A second side of the flexure element is secured to a first side of the PLC on which the optical element is formed such that the bulk element and the optical element are in optical alignment to within a first level of tolerance. Subsequent to the step of securing the second side of the flexure element, a force is exerted on at least a second side of the substrate to thereby flex the flexure element. The force causes sufficient flexure of the flexure element to optically align the bulk element and optical element to within a second level of tolerance that is more stringent than the first level of tolerance.

  • Patent number: 6956873
    Abstract: A broadband terminal interface unit for use in an HFC communication network includes a phase-locked loop for providing a smooth transition between a CMTS-provided “national” clock and a local clock when the CMTS clock is lost (or before it is required). By controlling the tracking range of the PLL, the sensitivity of the circuit is controlled so that some drift in the national clock can be accommodated without unnecessarily reducing the performance of the components within the broadband terminal interface unit.
