  • Patent number: 11920508
    Abstract: An anomaly determination device, an anomaly determination method, and a memory medium for a water pump are provided. An acquisition process acquires an input variable of a map from image data obtained by capturing an outer surface of the water pump. Execution circuitry obtains provisional determination results from maps, respectively. The provisional determination results are respectively obtained by executing the provisional determination processes for output variables output from the maps. A determination finalizing process treats, as a majority of the provisional determination results, a final determination result indicating whether coolant has leaked out of the water pump.

  • Patent number: 11749358
    Abstract: A semiconductor integrated circuit includes a register, a first interface circuit, an oscillation circuit that generates a first clock, a pll circuit, a control circuit, and a second interface circuit. The register stores numerical information representing a data size. The first interface circuit receives, from a first device, a first timing signal for data transfer. Responding to receipt of the first timing signal, the control circuit inputs the first timing signal to the pll circuit and counts the number of toggles of the first timing signal. When a counted number of toggles of the first timing signal matches a value corresponding to the numerical information, the control circuit inputs the first clock to the pll circuit. The second interface circuit transmits, to a second device, the first timing signal or a second timing signal, which corresponds to a second clock generated based on the first clock by the pll circuit.
