  • Patent number: 12085431
    Abstract: Provided is an ultrasonic flow sensor with improved practicality. An ultrasonic wave is transmitted and received by an ultrasonic element. A first flow rate value of a fluid in a pipe is calculated based on a propagation time difference of an ultrasonic signal, a measurement value corresponding to an ultrasonic velocity, and a parameter for identifying an inner diameter of the pipe. A second flow rate value of the fluid in the pipe is calculated based on a frequency shift of the ultrasonic signal and the parameter. The first flow rate value is calculated using a propagation time of the ultrasonic signal as the measurement value in accordance with a correspondence relationship among a distance of a path through which the ultrasonic wave propagates through the fluid in the pipe, a time for which the ultrasonic signal propagates in the path, and the ultrasonic velocity.

  • Patent number: 7433524
    Abstract: A motion image processing apparatus is disclosed. In the apparatus, a decoding part decodes frame data separated by a frame separating part based on the quality parameter. That is, a quality parameter calculating part calculates the frame data number possible to further store in a frame buffer obtained from an accumulated data volume detecting part, and a decode quality updating part updates the quality parameter for the decoding part. Moreover, a frame location determining part determines a next frame location to process based on the frame data number, and the frame location updating part indicates the next frame location to a frame separating part.

  • Patent number: 5038202
    Abstract: An image transmission system includes a modulating part for independently modulating a luminance signal and two kinds of color difference signals and a demodulating part for independently demodulating the modulated luminance signal and the two kinds of modulated color difference signals. The demodulating part includes a signal correcting part for shifting at least one of the modulated luminance signal and the two kinds of modulated color difference signals by a predetermined number of picture elements in a scanning line direction to correct an error introduced by the modulation.
