  • Patent number: 8349013
    Abstract: A method for stabilizing at least one spinal motion segment includes an expandable spacer in a collapsed state into the interspinous space between superior and inferior vertebrae such that the spacer extends through the sagittal plane defined by the spinous processes of the superior and inferior vertebrae. The spacer has a flexible membrane defining an interior cavity. The method includes expanding the spacer to an expanded state by forcing a fill material in a fluid state into the cavity with the spacer disposed in the interspinous space, and thereafter solidifying the fill material to a solid state in the cavity. The method may be performed through a percutaneous penetration in the patient's skin and may cause the first and second vertebrae to be distracted.

  • Patent number: 8351319
    Abstract: The present invention relates to cellular radio communication and in particular to providing information on neighbor cells to enable terminals to perform neighbor cell measurements. In the prior art the terminal attempts to make neighbor cell measurements in a reference signal structure that is the same in the neighbor cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighboring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbor cells.

  • Patent number: 8351874
    Abstract: Methods and apparatus are disclosed for automatically adjusting antenna impedance match in a wireless transceiver employing phase-amplitude modulation. According to some embodiments of the invention, a wireless transceiver comprises a transmitter circuit and a receiver circuit connected to the antenna by a transmit/receive duplexer. An electronically adjustable matching network is located between the transmitter output and the antenna. To control the adjustable matching network, a directional coupler is located between the transmitter output and the matching network to separate transmit signals reflected from the antenna system, including the antenna, the matching network and the T/R duplexer. The reflected transmit signals are routed to the receiver circuit, which digitizes the reflected signal and determines an antenna reflection coefficient based on the digitized reflected signal and the modulation signal used to create the transmit signal.

  • Patent number: 8348713
    Abstract: A flying disc is formed entirely of a knotted filament, such as knotted, stitched, or crocheted filament, which may comprise yarn, rope, or the like. A generally flat, generally circular web, defining a plane, is formed by pulling loops of the filament through other loops to form successive interconnected rows of knots using, e.g., crochet stitches. In one embodiment, the knotting proceeds in a helical pattern from a central portion of the circular web to a peripheral portion, with stitches added to an otherwise uniform stitching pattern as necessary to maintain a generally flat shape to the web. The center of the circular web may comprise knotted filament, or may include a void or hole. A circumferential lip connected to the periphery of the circular web and extending out of the plane of the circular web, at least during flight, is formed by dropping stitches from a uniform stitching pattern as necessary to create the desired shape.

  • Patent number: 8345793
    Abstract: A method and apparatus for compensating for ISI is described herein. A transmitter and receiver work together to develop pulse shaped OFDM symbols with reduced inter-channel ISI between pulse-shaped OFDM symbols transmitted on different sub-carriers at the same time, and inter-block ISI between pulse-shaped OFDM symbols transmitted on the same sub-carrier at different times. In addition, a pre-compensation element in the transmitter and/or a post-compensation element in the receiver compensate for diagonal ISI occurring between pulse-shaped OFDM symbols transmitted on different sub-carriers at different times.

  • Patent number: 8346315
    Abstract: Methods and apparatus are disclosed for operating a multi-mode wireless communications device to select a radio access technology (RAT) requiring the lowest energy consumption by the device for a desired operating mode. An exemplary method comprises scanning a plurality of frequency bands to determine a set of available radio access technologies that support the desired operating mode, and evaluating, for each available RAT, RAT-specific system parameters and RAT-specific operating conditions. Based on the evaluation, the RAT requiring the lowest energy consumption by the wireless device for the desired operating mode is selected.

  • Patent number: 8345809
    Abstract: In time varying OFDM systems, the effect of a non-ideal time synchronization may lead to a poor performance in terms of decoded average bit error rate versus the signal-to-noise ratio. The receiver apparatus (3) of the transmission system (1) estimates a subcarrier-dependent channel frequency response and determines an intercarrier interference spreading on the basis of a cyclic shift in symbols carried by the subcarriers. Therewith, an intercarrier interference included in an OFDM signal can be canceled, even in case of a non-ideal time synchronization.

  • Patent number: 8340202
    Abstract: In one aspect, the present invention greatly simplifies soft modulation calculations, in part by exploiting certain properties of Gray-mapped QAM constellations used in modulating symbols of interest. In at least one embodiment, the simplified processing includes performing the soft modulation separately for the real and imaginary parts of each symbol of interest, by using the Gray mapping to decompose each of the real and imaginary parts into binary soft modulations for each bit, and then using a computationally-efficient table lookup to calculate the binary soft modulation. Here, the look-up table comprises pre-computed bit contributions to the complex soft symbol value to be formed for the symbol of interest.

  • Patent number: 8339203
    Abstract: An on-chip power amplifier includes first and second variable capacitors connected in parallel with first and second windings, respectively, of an on-chip balun. The first balun winding connects between the differential outputs of an on-chip differential amplifier. Varying the first variable capacitor changes the imaginary part of the load impedance of the differential amplifier, while varying the second variable capacitor changes the real part of the load impedance of the differential amplifier. In one embodiment, the first and second variable capacitors are generally orthogonal, such that the first and second variable capacitors are less than 25% correlated. As a result, varying the first variable capacitor has little impact on the real part of the load impedance, and varying the second variable capacitor has little impact on the imaginary part of the load impedance. In this way the load impedance can be tuned to the optimum performance.
