  • Video encoding method, video encoding device, and video encoding program
    Patent number: 8345767
    Abstract: A video encoding method comprises the steps of converting syntax data of an image block into a binary sequence; encoding each symbol of the binary sequence subject to its corresponding context; estimating the number of bits required for the binary arithmetic encoding of the syntax data of the image block; deciding whether to encode the syntax data of the image block to output it responding to the estimated bit number; and updating the context corresponding the syntax data decided to be encoded and to be outputted and not updating the context corresponding to the syntax data decided not to be encoded and not to be outputted. The estimating step uses the maximum value of the number of arithmetic encoding output bits for its input symbols as the aforementioned number of bits.

  • Probe card, having cantilever-type probe and method
    Patent number: 7256591
    Abstract: A probe card is used to test an electronic device. The probe card includes a base plate and a cantilever-type probe arranged on the base plate. The cantilever-type probe has an end that contacts the contacted body and moves when contacting the contacted body. A stopper arranged on the base plate restricts the movement of the cantilever-type probe.

  • Probe card and probe contact method
    Publication number: 20030098702
    Abstract: An inexpensive probing card that has probe pins for contacting pads with high reliability. The probe pins are arranged on a base plate. The probe pins move along the pads when contacting the pads. A stopper restricts the movement of the probe pins.
