  • Patent number: 11964402
    Abstract: In a robot control system, the operation of a mobile robot that moves autonomously inside a facility is controlled based at least on an image captured by a photographing device that photographs a blind area located at a blind angle to the mobile robot. When entry of the mobile robot into a predetermined area corresponding to the blind area is detected, the amount of information obtainable from an image captured by the photographing device is increased.

  • Patent number: 11955785
    Abstract: A resin structure includes first and second resin bodies including first and second wall portions and first and second engagement portions, respectively. One of the first engagement portions engages with one of the second engagement portions and form a first engaging part. Another one of the first engagement portions engages with another one of the second engagement portions and form a second engaging part. The first engaging part is positioned on a further front side than the second engaging part in an attaching direction of the second resin body to the first resin body. When the second resin body is rotated toward the first resin body with the first engaging part as a center of rotation and with the one of the first engagement portions being engaged with the one of the second engagement portions, the first wall portion is prevented from interfering with the second wall portion.

  • Patent number: 10007214
    Abstract: An image forming apparatus includes a conveying device; a fixing device; and a controller. The controller is configured to perform: in response to determining that a first condition is met, starting sheet conveyance by the sheet conveying device upon expiration of a first predetermined period of time starting from receipt of a print instruction; and in response to determining that a second condition different from the first condition is met, starting sheet conveyance by the sheet conveying device at selective one of a first timing and a second timing. The second timing is selected upon determination that an accumulated amount of usage of the fixing device is not greater than a predetermined amount. The first timing is a timing at which a sensed temperature has reached a first threshold value. The second timing is a timing at which a second predetermine period of time has expired after the first timing.
