  • Publication number: 20190018133
    Abstract: In an object detection method, a moving speed v0 of a radar device and an angle ?1 defined between a moving direction of the radar device and a reception direction of a radar wave reflected on a target are acquired, a first function which expresses a relative speed v1 between the radar device and the target by the speed v0 and the angle ?1 in a non-multipath environment model and a second function which expresses the speed v1 in a multipath environment model are formed, an actual relative speed between the radar device and the target is calculated from a reception signal of the radar wave by using the multipath environment model, and it is determined that the reception signal is derived from a stationary object when a point defined by the ?1 and the actual relative speed is positioned between the first function and the second function.

  • Publication number: 20180341012
    Abstract: A ghost removal method includes steps of detecting, estimating and excluding. In the detecting, a position and a relative speed of a target moving object, and a position of a surrounding stationary object are detected with radio waves. In the estimating, a position and a relative speed of a ghost by the target moving object are estimated based on the detected position and relative speed of the target moving object and the position of the surrounding stationary object. In the excluding, a detected point where the estimated position and the relative speed of the ghost are detected is excluded from a candidate detection point of a moving object which is detected with radio waves.

  • Patent number: 9433262
    Abstract: A molding hook and loop fastener includes a plurality of surface fastener portions and a coupling member that is formed of a resilient body and connects the surface fastener portions. The coupling member includes a pair of vertical wall coupling portions which is continuously disposed along a longitudinal direction on both sides in between an engaging element area and which connects the surface fastener portions. With this configuration, when the molding hook and loop fastener is integrally molded to a cushion body, it is possible to prevent a resin material from penetrating into the engaging element area of the surface fastener portion and to stably secure a desired fastening strength at the engaging element area.

  • Patent number: 9387878
    Abstract: A target-travel-path generating circuit calculates a target travel path along which a controlled object can travel in the future from a current controlled object position. An ideal-control-signal calculating circuit calculates a control profile to travel along the target travel path, and a difference calculating circuit calculates a difference between an ideal control magnitude and a current control magnitude. A controller controls an operation system based on a magnitude of the difference to assist a control operation and a control-operation-state of an operator, an environment-state, and a required operation-precision. The operator receives assistance corresponding to the magnitude of the difference from an ideal control state, the control-operation-state, the environment-state, and the required operation-precision. An outputted control-operation assistance control is suitable for conditions that characterize the operator state, the environment, and the controlled object.
