Patent number: 12085431Abstract: 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.Type: GrantFiled: July 8, 2022Date of Patent: September 10, 2024Assignee: KEYENCE CORPORATIONInventors: Yasunori Kawaguchi, Masaki Wada, Masaki Ishihara, Daishiro Ishikawa, Ryuma Miyake

Patent number: 10339418Abstract: A computation unit calculates luminance differences of individual pixel pairs in a feature area and calculates, based thereon, a local feature value formed from bit values respectively corresponding to the pixel pairs. Specifically, the computation unit calculates a specific luminance difference for a specific pixel pair corresponding to a specific bit value and then compares the result with a specified range including a zero point of luminance difference. Then a first value is assigned to the specific bit value when the specific luminance difference is greater than the upper bound of the specified range. A second value is assigned to the same when the specific luminance difference is smaller than the lower bound of the specified range. A predetermined one of the first and second values is assigned to the same when the specific luminance difference falls in the specified range.Type: GrantFiled: September 14, 2017Date of Patent: July 2, 2019Assignee: FUJITSU LIMITEDInventors: Masahiko Sugimura, Masaki Ishihara, Susumu Endo, Hiroaki Takebe, Takayuki Baba, Yusuke Uehara
