    Abstract: According to one embodiment, a selection device selects an acquisition method of a grip point for gripping an object. Based on object data corresponding to a characteristic of the object, the selection device selects one of a first method or a second method. In the first method, the selection device calculates exterior shape data of the object from an image of the object, and calculates the grip point by using the exterior shape data. In the second method, the selection device inputs the image to a first model that is trained and acquires the grip point output from the first model.

  • Patent number: 11889037
    Abstract: A printer includes a printing unit powered from a battery which is charged by a charge IC, and a processor. The processor sets a mode of the printer to a print mode, and sets the mode to a low-power mode in which total power consumption of the printer is lower than that in the print mode, in a state that the printing unit stops printing. In a case where the processor sets the mode to the low-power mode, the processor sets the mode to a first low-power mode, in which the charge IC is driven at a first SW frequency, when the charge IC works to charge the battery, and sets the mode to a second low-power mode, in which the charge IC is driven at a second SW frequency lower than the first SW frequency, when the charge IC stops the charge of the battery.
