  • Patent number: 11120298
    Abstract: According to an embodiment, a computing device includes a processing circuitry. The processing circuitry receives an input of tensor data. The processing circuitry sets a window in the tensor data. The processing circuitry compares, for each pair of coordinates in the tensor data within the window, a pixel value at the pair of coordinates with one or more thresholds, and selects a weight value corresponding to a comparison result. The processing circuitry adds the weight values selected for the respective pairs of coordinates to obtain a cumulative value. The processing circuitry derives a value based at least in part on the cumulative value.

  • Publication number: 20210265916
    Abstract: In a power supply device, a primary winding is connected to, out of drain-source terminals of FETs as the subject of soft switching control, a source terminal and a drain terminal where the potential of the drain-source terminals is adjusted. In a case where a current value detected by a current detection unit is equal to or smaller than a reference current value defined in advance, a controller allows the current flowing backward due to resonance of a coil and a capacitor of a smoothing circuit to flow in a secondary winding via a rectifier circuit.

  • Publication number: 20210264074
    Abstract: A static matrix model in a viscoelastic body is generated for each environmental temperature condition. A generalized Maxwell model is generated for each environmental temperature condition using a matrix of the static matrix model. A spring coefficient and a damper viscosity coefficient of a material test piece is identified as a function of a strain rate norm based on a measurement result of the material test piece using a temperature-time conversion rule. An average strain rate of a part is identified as a function of a displacement rate vector. A dynamic spring coefficient and a damper viscosity coefficient of the part are identified as a function of a component of the displacement rate vector. A generalized Maxwell model for analysis is generated by applying the dynamic spring coefficient and the damper viscosity coefficient identified as the function of the component of the displacement rate vector to the generalized Maxwell model.
