  • Patent number: 11938945
    Abstract: An information processing system includes one or more vehicles, and a server communicable with the one or more vehicles. The vehicle acquires an image obtained by imaging a road on which a host vehicle is located. The vehicle or the server determines a degree of difficulty in traveling on the road due to snow cover from the image. The server stores the degree of difficulty in traveling for each of one or more roads, and provides information to a client by using the stored degree of difficulty in traveling for each of one or more roads.

  • Publication number: 20210294573
    Abstract: A multiply-accumulate operation device, circuit and method are disclosed. In on example, a multiply-accumulate operation device includes input lines, multiplication units, an accumulation unit, a charging unit, and an output unit. Pulse signals having pulse widths corresponding to input values are input to the input lines. The multiplication units generate, based on the pulse signals, charges corresponding to multiplication values obtained by multiplying the input values by weight values. The accumulation unit accumulates a sum of the charges corresponding to the multiplication values. The charging unit charges the accumulation unit at a charging speed associated with its accumulation state. The output unit outputs a multiply-accumulate signal representing a sum of the multiplication values by executing threshold determination using a threshold value associated with the accumulation state of the accumulation unit on a voltage held by the accumulation unit after the charging by the charging unit is started.
