  • Method and apparatus for generating delays
    Publication number: 20070152725
    Abstract: One embodiment pertains generally to a method of delaying based on a single clock signal. The method includes providing a first clock signal and generating a second clock signal based on the first clock signal and a third clock signal that is the inverse of the second clock signal. The method also includes generating a unit of delay based the first clock single and generating a half unit of delay based on the first and second clock signal.

  • Method and system for programming for image enhancement
    Publication number: 20070133053
    Abstract: In a method of programming for image enhancement, a content addressable memory is accessed. At least one template is transferred into the content addressable memory. A random access memory is accessed. Enhancement data is transferred into the random access memory. Video data input is inputted into the content addressable memory. Enhancement data is outputted from the random access memory based on the video data matching at least one template.

  • Gas flow meter
    Patent number: 5448919
    Abstract: An improved gas flow meter which measures the time of travel of a soap film through a fixed volume to compute gas flow rate. A portable meter includes infrared sensors which detect the passing of a soap film, a timing circuit to determine the time of travel between the beginning and end of the fixed volume and a method of blocking the infrared portion of ambient light to allow for use outdoors. The device has a unique method of generating the soap bubble and for breaking the soap bubble at the end of the fixed volume. The unique flow unit, including flow cell and fixed sensors, is calibrated to determine the fixed volume which is stored in a nonvolatile memory location as a part of the flow unit.
