  • Publication number: 20240138815
    Abstract: A push wave transmission unit transmits a push wave to a biological tissue of a subject. A tracking wave transmission/reception unit transmits a tracking wave to the biological tissue and receives a reflected ultrasound wave reflected by the biological tissue. An elasticity analysis unit measures a propagation velocity of a shear wave generated in the biological tissue by the push wave and measures an elastic property of the biological tissue based on the propagation velocity, and measures the propagation velocity of the shear wave based on a measurement signal obtained by the reflected ultrasound wave received by the tracking wave transmission/reception unit. A controller determines whether to re-measure the elastic property according to an unnecessary component included in the measurement signal. When determining to re-measure the elastic property, the ultrasound diagnostic apparatus re-measures the elastic property by changing an acoustic property of the push wave according to the unnecessary component.

  • Patent number: 11915536
    Abstract: An anomaly determination apparatus for a vehicle that includes a transmission includes an execution device and a memory device. The memory device is configured to store map data that defines pre-trained map, which has been trained through machine learning. When a variable representing time-series data of a rotation speed of a gear is fed to the map as an input variable, the map outputs a state variable representing a state of the gear as an output variable. The execution device is configured to execute: an obtaining process that obtains the variable representing the time-series data as a value of the input variable; and a determination process that determines whether there is an anomaly in the transmission based on a value of the output variable that is output by the map when the value of the input variable is fed to the map.
