  • Patent number: 11962433
    Abstract: A switch device includes a plurality of communication ports; a switch unit configured to relay a frame, which has been transmitted from a function unit and to which information including an ID of a VLAN is added, to another function unit via a communication port; and a duplication unit configured to, when the diagnosis device is connected to another switch device, duplicate the frame to be relayed via a designated communication port among the plurality of communication ports, and generate a duplicate frame for diagnosis that is a frame obtained by adding, to a duplicate frame obtained through the duplication, specific information indicating that the duplicate frame for diagnosis should be transmitted to the diagnosis device. The switch unit outputs the duplicate frame for diagnosis generated by the duplication unit from a communication port corresponding to the other switch device.

  • Publication number: 20230359224
    Abstract: A moving body (MB) includes a space recognition processor (VP) and an operation controller (FC). The space recognition processor (VP) generates odometry information (SPI) and map information (MI) of the moving body (MB). The operation controller (FC) generates position and orientation information (PI) of the moving body (MB) based on the odometry information (SPI). The operation controller (FC) causes the moving body (MB) to perform autonomous movement based on the position and orientation information (PI) at an abnormal time when an abnormality occurs in the moving body (MB). The operation controller (FC) controls the operation of the moving body (MB) according to a control instruction generated by an application processor (AP) based on the position and orientation information (PI) and the map information (MI) at a normal time when the moving body (MB) operates normally.

  • Patent number: 7878992
    Abstract: Tow forces can be measured only by providing one force sensor in a device structure, and a drive system is driven so as to assist an external force by detecting it. A value at a force sensor (114) at the moment when a foot switch (121) is set as the original point (detection reference) of a force to be assisted. Variations of the force after the original point setting is measured by the force sensor (114) the difference between the measured value and the assist original point is obtained, and a force to be assisted is detected. Depending on the magnitude of the force to be assisted, assist operation is performed by causing a drive force to act on a foot such that the force to be assisted is reduced. When the force is assisted reaches zero, the assist operation is completed. Then, two forces, or “a force acting on a patient's foot” and “a force applied to the foot” from the outside, are detected by the one force sensor (114).

  • Publication number: 20100268545
    Abstract: An examination-schedule memory unit stores an examination schedule including a plurality of examinations. An operation-status acquisition unit acquires the operation status of a washing apparatus that washes a scope used for an examination. A rescheduling unit changes the start time of at least one examination included in an examination schedule in accordance with the operation status acquired by the operation-status acquisition unit. The rescheduling unit may specify the washing-completion time of the used scope based on the washing-start time acquired by the operation-status acquisition unit, determine whether or not an already-washed scope will be available at the start time of each examination based on the specified washing-completion time and the start time of each examination, and change, when it is determined that there will be no already-washed scopes available, the start time of the examination to be after the time at which an already-washed scope will become available.
