  • Patent number: 7139700
    Abstract: Linear predictive speech coding system with classification of frames and a hybrid coder using both waveform coding and parametric coding for different classes of frames. Phase alignment for a parametric coder aligns synthesized speech frames with adjacent waveform coder synthesized frames. Zero phase alignment of speech prior to waveform coding aligns synthesized speech frames of a waveform coder with frames synthesized with a parametric coder. Inter-frame interpolation of LP coefficients suppresses artifacts in resultant synthesized speech frames.

  • Patent number: 7139959
    Abstract: A low density parity check (LDPC) code that is particularly well adapted for hardware implementation of a belief propagation decoder circuit (38) is disclosed. The LDPC code is arranged as a parity check matrix (H) whose rows and columns represent check sums and input nodes, respectively. The parity check matrix is grouped into subsets of check sum rows, in which the column weight is a maximum of one. The decoder circuitry includes a parity check value estimate memory (52). Adders (54) generate extrinsic estimates, from immediately updated input node probability estimates, and the extrinsic estimates are applied to parity check update circuitry (56) for generating new parity check sum value estimates. These parity check sum value estimates are stored back into the memory (52), and after addition with the extrinsic estimates, are stored in a column sum memory (66) of a corresponding bit update circuit (60) as updated probability values for the input nodes.

  • Patent number: 7139035
    Abstract: A method of detecting both linear and non linear noise in video data. Linear noise is detected on a line-by-line basis, by blocks within each line. Non linear noise is detected during horizontal blanking periods. The method provides a noise floor value for linear noise and an impulse noise flag for non linear noise, both of which are delivered to a noise reduction filter.

  • Patent number: 7139040
    Abstract: A system and method for correcting non-periodic event time of arrival data in a control system. The system and methods are particularly applicable to the speed and phase control of a color wheel used with spatial light modulators. The circuitry automatically and accurately compensates for non-periodic index signals occurring when one or more index marks on the color wheel are misplaced. The system adds to or subtracts clock pulses from the actual time of arrival of a specific index mark until the corrected value equals the desired or nominal value. The system then generates a PWM signal for controlling the speed and phase of the color wheel.

  • Patent number: 7139229
    Abstract: The present invention offers an optical disk determination circuit that can improve the stability of the operation to detect the peak (pulse signal) of the received light signal, and that can improve the stability of the optical disk determination operation. When determining the type of optical disk corresponding to the depth from the surface of the plane on which a light beam is irradiated to the data recording layer, light is irradiated while varying the focal position of the light beam at a constant velocity in one direction of the depth direction from the surface of the optical disk. The bottom level of the received light signal corresponding to the intensity of this reflected light is clamped at a specified level by the bottom clamp circuit 43. The received light signal with the bottom level clamped is compared with a specified reference voltage Vref by the comparator 45, and the received light signal peak (pulse signal) is detected corresponding to the results of this comparison.

    Abstract: An output buffer having a first pull-up transistor and a first pull-down transistor connected in series between two nodes of a power supply, their common connection node being connected to the output node. A logic circuit receives an input signal at a logic level and controls the voltage at the gates of the first pull-up transistor and the first pull-down transistor to provide the logic level at the output node. A second pull-up transistor and a second pull-down transistor are connected in series between the two nodes of the power supply, their common connection node being connected to the output node. A control circuit provides an output indicating when the supply voltage is below a predetermined level.
