  • Publication number: 20100110305
    Abstract: A broadcasting signal receiver system containing a multi-standard-compatible dedicated processing unit and a general system resource is disclosed, wherein the multi-standard-compatible dedicated processing unit is configured to process one or more tuning processing steps and/or one or more demodulation processing steps, and wherein the general system resource is configured to process at least one collaborative demodulation processing step with the multi-standard-compatible dedicated processing unit via a high-speed data transfer interface. By utilizing the general system resource for at least one demodulation processing step using the high-speed data transfer interface such as USB 3.0 or PCI Express, the broadcasting signal receiver system can have a flexible design for future updates and a cost-effective compatibility to a multiple number of broadcasting standards without requiring the dedicated processing unit to use more application-specific hardware resources.

  • Publication number: 20090319218
    Abstract: In some embodiments, each interferometric modulator has a stiction threshold voltage. If a voltage above the stiction threshold voltage is applied to the interferometric modulator, the interferometric modulator enters a stiction state permanently, i.e., becomes “stuck,” and the interferometric modulator becomes inoperable. Disclosed are apparatuses, methods and computer-readable media for testing a panel of interferometric modulators. A ramped voltage waveform is applied to a plurality of interferometric modulators of the panel. In response to applying the ramped voltage, the stiction threshold voltage is identified. At or above this voltage, the number of stuck interferometric modulators in the panel reaches or exceeds a first threshold number, for example, 50% of the total number of the interferometric modulators constituting the panel. The embodiments can be used to establish stiction benchmark for panel manufacturing processes, to collect data for generating statistical distribution, etc.

  • Publication number: 20090228756
    Abstract: An iterative decoder circuit includes an N number of sub-decoders, N?1 of the sub-decoders each being responsive to a baseband signal from one of M number of signal processing circuits. Each of the N?1 number of sub-decoders includes, an inner delay responsive to a baseband signal provided by a corresponding signal processing circuit for generating an inner delayed signal, a modified decoder that receives the inner delayed signal and generates a set partition signal, some of which have less errors than previous set partition signals. An Nth inner delay is responsive to the baseband signal and provides an Nth inner delayed signal. An Nth modified decoder is responsive to the Nth inner delayed signal and to the set partition signal and provides an output signal, wherein the probability of error of the output signal is reduced by correcting errors in some of the set partition signals.

  • Patent number: 7251596
    Abstract: The present invention provides a unique wave-trigon transformation (WTT) method for performing transformation process over a wave signal. The present invention also provides a pitch detecting method and apparatus for detecting pitch based on the WTT process as well as a sentence detecting method and apparatus for detecting a sentence in a sound signal based on the WTT process. The pitch detecting method and apparatus can effectively detect pitch in a sound signal. In the WTT process, an inputted wave signal (such as a sound signal) is transformed into a series of trigons, and an energy-width spectrum is formed using these trigons. For a sound signal containing voice, the distribution of trigons transformed from the sound signal has a certain pattern. By analyzing the pattern, whether a pitch is contained in the sound signal can be determined. In particular, existence of a pitch can be determined by determining and evaluating the periodicity of trigons in a candidate chained peak in the energy-width spectrum.
