Patents by Inventor Ming-Yu Chuang

Ming-Yu Chuang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7706470
    Abstract: A Global Positioning System (GPS) acquisition method is provided. A GPS signal is first received, comprising a plurality of data bits, each repeating for a bit period. A search space is then formed, comprising a plurality of elements each associated with a presumed offset and a presumed code phase. Before bit-transition of each bit period, element values of the elements are accumulated by substituting the data bits into a coherent-combination algorithm. After bit-transition of each bit period, the element values are accumulated by substituting the data bits into a differential-coherent combination algorithm.
    Type: Grant

    Date of Patent: April 27, 2010
    Assignee: Mediatek Inc.
    Inventors: Ming-Yu Chuang, Kai-Ten Feng
  • Patent number: 7415421
    Abstract: A method for managing a plurality of fabrication facilities comprises the steps of: identifying a proposed new or modified fabrication method, evaluating the fabrication method against decision criteria based on use of the fabrication method to fabricate a first product at a first one of the fabrication facilities, verifying the fabrication method against the decision criteria, based on using the fabrication method to fabricate a second product at a second one of the fabrication facilities, and adopting the fabrication method as a best known method among the plurality of fabrication facilities, if the fabrication method satisfies the decision criteria.

  • Publication number: 20040243267
    Abstract: System and method for controlling and propagating engineering changes in integrated circuit manufacturing. A preferred embodiment comprises a technical board (T/B, for example, T/B 220) and a technical database (TTD, for example, TTD 225). The T/B 220 gives permission to an IC fab (for example, IC fab A 205) prior to the IC fab making any changes to a fabrication process. The IC fab then makes an experimental run and reports the results to the T/B 220. The results may then be verified by additional experimental runs at other IC fabs. If the results are acceptable to the T/B 220, a new best known method is created and stored in the TTD 225 and is propagated to other IC fabs if these IC fabs uses the technology relevant to the best known method.
