  • Publication number: 20240119621
    Abstract: The present disclosure provides a system for supporting a movement of a moving body in a predetermined area. The system acquires an image captured by an infrastructure camera such that the image includes a plurality of markers arranged in the predetermined area. The system compares the image acquired this time and the image acquired previous time. The system detects a position change marker among the plurality of markers whose position in the image acquired previous time changes from that in the image acquired this time. The system determines that the infrastructure camera is out of position when it is detected that number of the position change marker is equal to or more than a predetermined number. The system determines that the infrastructure camera is not out of position when it is detected that number of the position change marker is less than the predetermined number.

  • Patent number: 11952239
    Abstract: A sheet feeding device includes a feeding roller pair, a detecting portion, a first changing portion, a second changing portion, and a controller for controlling the first changing portion and the second changing portion. The controller starts a first feeding operation for feeding a sheet toward the obliquely feeding roller pair in a nipping state of the feeding roller pair and then starts a second feeding operation for feeding the sheet for abutting a side end of the sheet against the reference member in the nipping state of the obliquely feeding roller pair. The controller changes, after the first feeding operation is started and before the second feeding operation is started, a start timing of the second feeding operation on the basis of a detection result of a position of the side end of the sheet detected by the detecting portion.

  • Patent number: 11705609
    Abstract: A contact structure causing a first electric device to be electrically connected to a second electric device includes first terminals and second terminals. The second terminals include contact projections to be electrically connected to the first terminals, and cleaning projections located closer to an opening side of a fitting part of the second electric device than the contact projections to be brought into contact with the first terminals. The contact structure is configured such that the contact projections are not in contact with a surface of an outer case of the first electric device or surfaces of the first terminals before the cleaning projections climb over the first terminals. The contact structure is also configured such that the contact projections are brought into contact with the surfaces of the first terminals after the cleaning projections climb over the first terminals.

  • Patent number: 10855017
    Abstract: Provided is a connector terminal, including: a tubular section having a lance formed by cutting a part of a peripheral wall thereof and raising the same about its base part. At least a portion of the peripheral wall in which the lance is cut and raised is curved to bulge outward as seen from an opening direction of the tubular section. The lance has a pair of end edges opposed to each other in a width direction orthogonal to a direction in which the lance extends, and at least one of the pair of end edges at least on the side of the base part of the lance is formed to come close to an opposed one of the at least one of the end edges as it advances toward a leading end of the lance. Also provided are a connector including the connector terminal, and a size adjustment device.
