  • Mutant N-acetylglutamate synthase and method for L-arginine production
    Publication number: 20050026258
    Abstract: L-arginine is produced using a bacterium belonging to the genus Escherichia harboring a mutant N-acetylglutamate synthase in which the amino acid sequence corresponding to positions from 15 to 19 in a wild type N-acetylglutamate synthase is replaced with any one of amino acid sequences of SEQ ID NOS: 1 to 4, and feedback inhibition by L-arginine is desensitized.

  • Image compression and synthesis for video effects
    Publication number: 20040131261
    Abstract: An encoder compresses a set of still images and parameterizes (with effect parameters) additional images synthesized from the set of still images. A decoder decompresses the set of still images and synthesizes the additional images using the effect parameters.

  • Smart optical microphone/sensor
    Patent number: 6603105
    Abstract: The invention provides a smart optical microphone/sensor for sensing distances to a membrane or to a light-reflecting surface, including a source of light for illuminating the membrane or light-reflecting surface; a photodetector for receiving light reflected from the membrane or light-reflecting surface and for producing output signals; adjustable means for supplying power to the source of light, and a pre-amplifier for amplifying the output signals, whereby the sensitivity of the microphone/sensor can be adjusted.
