  • Patent number: 7620173
    Abstract: A headset having an integrated boom clip for attaching the headset to an object. The headset includes a bottom enclosure, a hinge system coupled to the bottom enclosure, and a boom coupled to the hinge system. The bottom enclosure, boom and hinge system are configured so that the boom can be selectively positioned relative to the bottom enclosure in a closed position or in an open position. In the closed position the boom can be used to clip the headset to an object such as, for example, the user's clothing.

  • Patent number: 7511532
    Abstract: Reconfigurable electronic structures and circuits using programmable, non-volatile memory elements. The programmable, non-volatile memory elements may perform the functions of storage and/or a switch to produce components such as crossbars, multiplexers, look-up tables (LUTs) and other logic circuits used in programmable logic structures (e.g., (FPGAs)). The programmable, non-volatile memory elements comprise one or more structures based on Phase Change Memory, Programmable Metallization, Carbon Nano-Electromechanical (CNT-NEM), or Metal Nano-Electromechanical device technologies.

  • Patent number: 7494849
    Abstract: Phase change devices, and particularly multi-terminal phase change devices, include first and second active terminals bridged together by a phase-change material whose conductivity can be modified in accordance with a control signal applied to a control electrode. This structure allows an application in which an electrical connection can be created between the two active terminals, with the control of the connection being effected using a separate terminal or terminals. Accordingly, the resistance of the heater element can be increased independently from the resistance of the path between the two active terminals. This allows the use of smaller heater elements thus requiring less current to create the same amount of Joule heating per unit area. The resistance of the heating element does not impact the total resistance of the phase change device.

  • Patent number: 7394878
    Abstract: Methods and apparatus for determining a dominant frequency contained in a multi-frequency analog signal. An apparatus includes a first matched filter pair and a second a second matched filter pair. Both the first matched filter pair and the second matched filter pair are configured to receive in-phase (I-phase) and quadrature-phase (Q-phase) digital samples of a digitized multi-frequency analog signal. The summed magnitudes of outputs of the first and second matched filter pairs provide an indication of a dominant frequency represented in the digital samples. The first matched filter pair may include first and second matched filters, where the first matched filter includes a multiplier operable to multiply, on a sample-by-sample basis, a sample by a coefficient. A sample comprises an n-bit digital representation of either the I-phase amplitude or the Q-phase amplitude at a given instant. The coefficients are the terms required to complete the matching functions (e.g. 1-bit Walsh coefficients).

  • Patent number: 7280073
    Abstract: A method for determining direction of transmission using an antenna array having a number of panels is disclosed. Each panel is configured to receive signals. According to one aspect of the method, each of the panels is directed to receive signals from a transmitting node. For each panel, a first table having data representing received signal power difference between the panel and a first neighboring panel and a second table having data representing received signal power difference between the panel and a second neighboring panel are built. The panel with the maximum received power is identified. For the identified panel, a first gain table and a second gain table corresponding to its first and second neighboring panels are searched to identify a first transmission angle and a second transmission angle, if any. A transmission angle relative to the transmitting node is determined using the first and second transmission angles.
