  • Method to improve performance and reduce complexity of turbo decoder
    Patent number: 7333419
    Abstract: One aspect of the invention relates to a method and embodiment for decoding a sequence of frames in a communication system having a predetermined decoding time constraint per frame. The first frame of a sequence of frames is decoded for a time period longer than the predetermined time constraint, and at least one other frame of the sequence of frames is decoded in a time period less than the predetermined time constraint. Thus, an average decoding time of all decoded frames is less than or equal to the predetermined time constraint.

  • Directional sound system with messaging
    Patent number: 7330125
    Abstract: An exit path indicating device incorporates at least a first port for receiving an alarm indicating signal. In normal operation upon receipt of the alarm indicating signal, the device outputs verbal and non-verbal indicators of the presence of an alarm condition for use in evacuating the region. A second port disables the non-verbal outputs. The second port can be coupled to a local sensor which provides an indication of a hazardous or alarm condition adjacent to or on the exit or egress path. If the sensor is indicating the presence of a hazardous or alarm condition, the non-verbal outputs can be disabled, while verbal directions can continue to be emitted.

  • Method for producing silicon wafer
    Patent number: 7329317
    Abstract: The present invention is to produce a silicon crystal wherein the boron concentration in the silicon crystal and the growth condition V/G are controlled so that the boron concentration in the silicon crystal is no less than 1×1018 atoms/cm3 and the growth condition V/G falls within the epitaxial defect-free region ?2 whose lower limit line LN1 is the line indicating that the growth rate V gradually drops as the boron concentration increases. A silicon wafer is also produced wherein the boron concentration in the silicon crystal and the growth condition V/G are controlled so as to include at least the epitaxial defect region ?1, and both the heat treatment condition and the oxygen concentration of the silicon crystal are controlled so that no OSF nuclei grow to OSFs.

  • Collaboration between wireless LAN access points using wired LAN infrastructure
    Patent number: 7330734
    Abstract: A method for mobile communication includes arranging a plurality of access points in a wireless local area network (WLAN) to communicate on a common frequency channel with a mobile station, and linking the access points together by cables in a wired local area network (LAN). When one or more of the access points receive an uplink signal transmitted over the WLAN by the mobile station on the common frequency channel, the access points send messages over the LAN and arbitrate among themselves based on the messages so as to select one of the access points to respond to the uplink signal.
