  • Publication number: 20190156665
    Abstract: An investigation assist device includes a processor and a storage that records road map information including a plurality of intersections and captured video of each of the cameras in association with camera information and intersection information. The processor retrieves a vehicle based on the captured video of each of the cameras installed at one or more intersections within a predetermined distance range from the intersection where the event has occurred, based on input information including date and time information when the event has occurred, the intersection information where the event has occurred, and feature information of the vehicle having caused the event. The processor updates detection date and time information of the vehicle from reception date and time information on a report indicating an occurrence of the event to detection date and time information of the vehicle.

  • Publication number: 20150292493
    Abstract: A fluid-pressure pump operated by a drive force of an electric motor is configured compact. A cam mechanism and a pump portion are disposed coaxial with a rotational axis of an output shaft of an electric motor. A cam mechanism includes a rotational member rotating in unison with the output shaft and a cam member having a cam face to which the rotational member comes into contact. The pump portion includes a piston which reciprocates in unison with the cam member and a spring for operating the piston in a reverse direction. At the time of rotation of the output shaft, the cam mechanism operates the piston in the forward direction by a pressing force applied from the rotational member to the cam face, and the spring, with its urging force, operates the piston in the reverse direction.
