Abstract: A management system manages travel of at least one vehicle, and includes a vehicle and a travel management apparatus. The vehicle includes motors, a drive unit to move the vehicle by controlling the motors, a first communication circuit, and a control circuit. The travel management apparatus includes a signal processing circuit to generate an nth command for causing the vehicle to move from an n (n: a positive integer)th location to an (n+1)th location and a second communication circuit. When the vehicle arrives in a region defined for the (n+1)th location while moving from the nth location toward the (n+1)th location, the vehicle transmits a notification of arrival-in-region to the travel management apparatus. Upon receiving the notification of arrival-in-region, the travel management apparatus generates an (n+1)th command for causing the vehicle to move from the (n+1)th location to an (n+2)th location, and transmits it to the vehicle.

Abstract: A mobile unit control device includes an imaging unit, an identification unit, and a control unit. When installed on a mobile unit, the imaging unit captures at least a portion of the surroundings of the mobile unit to obtain an image thereof. When the image captured by the imaging unit includes a figure of a person, the identification unit determines a trunk of the person in the figure of the person as a representative point. The control unit controls a movement of the mobile unit on the basis of the position of the representative point determined by the identification unit in the image.

Abstract: An optical deflector includes a plurality of piezoelectric unimorph oscillating bodies (210a to 210d) that cause a reflecting plate (1) to oscillate rotationally, centering upon a pair of flexible support units (2a and 2b). The optical deflector forms a single structure of the oscillating plates (23a to 23b), the reflecting plate (1), the flexible support units (2a and 2b), and a support body (9), by connecting one set of the terminals of the oscillating plates (23a to 23d) of the suite of piezoelectric unimorph oscillating bodies (210a to 210d) to the flexible support units (2a and 2b), and connecting the other set of terminals to the support body (9). Furthermore, the plurality of piezoelectric unimorph oscillating bodies (210a to 210d) each respectively comprise a plurality of parallel oscillating bodies (23a1 to 23a-3, 23b-1 to 23b-3, 23c-1 to 23c-3), and (23d-1 to 23d-3), and a suite of parallel actuators (28a-1 to 28a-3, 28c-1 to 28c-3, and 28d-1 to 28d-3).
