  • Patent number: 12007822
    Abstract: A power supply shutoff device includes a movable section, a driving section, a power supply device, a power distribution section, an electric power supply circuit, and a supply control section. The movable section is configured to travel on a traveling path provided along a board production line in which multiple board work machines, which perform a predetermined board work on a board, are installed side by side. The driving section is provided in the movable section and configured to cause the movable section to travel by using supply electric power supplied from the board work machine with non-contact power feeding. The supply control section is configured to stop a supply of the electric power to the electric power supply circuit when drive electric power for driving the board work machine is shut off in at least one board work machine among the multiple board work machines.

  • Patent number: 11992765
    Abstract: A computer system detects occurrence of an action exchange in which one of a player character and an opponent character performs a first action and another one of the player character and the opponent character performs a second action to mutually exchange the actions. Based on a first stiff time related to the first action, a second stiff time related to the second action, and a time difference between the first stiff time and the second stiff time, when a stiff time (hereinafter referred to as an “own stiff time”) related to an action performed by the player character is shorter than a stiff time related to an action performed by the opponent character, the computer system presents a player controlling the player character with a recommended candidate action recommended to be performed after an end of the own stiff time.
