Patents by Inventor Chien Han LIAO

Chien Han LIAO 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).

  • Publication number: 20240219465
    Abstract: A method and an apparatus for integrated circuit testing are provided. The method includes: operating a tester to perform a qualitative testing on devices in the integrated circuit by following electrical addresses of the devices, and to introduce an original verification pattern during the qualitative testing, such that a verification pattern corresponding to the original verification pattern can be converted from a raw data of a result of the qualitative testing; converting the raw data to a test graph presented by physical addresses, by using pre-determined scramble equations; and identifying portions of the verification pattern appeared in the test graph and comparing the portions of the verification pattern with corresponding portions of the original verification pattern by pattern recognition, and correcting the pre-determined scramble equations according to comparison result.
    Type: Application

  • Patent number: 8644234
    Abstract: A wireless device for selecting a connection target based on signal quality, a system and a method thereof are provided. The invention selects a candidate device having the best signal quality and duration of the signal quality is not less than a threshold reaching a certain time. If the selected candidate device also selects the wireless device, a unique connection is established between the wireless device and the candidate device. In a dynamical and complicated environment, the disclosed system and the method can build up a stable linear topology through automatic negotiation among wireless devices. The invention then achieves the effect of updating topology in time to adapt to environment changes.
