  • Patent number: 11340609
    Abstract: A driving guidance system that provides a driving guidance to a driver when the driver makes operations to remotely control a vehicle in a driving route. The driving guidance system includes at least one driving guidance equipment, an analytic engine, a control platform. The driving guidance equipment is distributed along the driving route for recording data of the vehicle. The analytic engine receives and analyzes the data of the vehicle to generate a plurality of features of the vehicle. The control platform further includes a real virtuality objects generator and a display. The real virtuality objects generator generates a plurality of real virtuality objects based on the features of the vehicle and the display shows the real virtuality objects to the driver of the vehicle for providing the driving guidance.

  • Patent number: 11107364
    Abstract: A system that simulates force feedback of a remote-control vehicle in a motion chair, which includes a plurality of cameras (110,120) mounted on the vehicle (100), an image stabilization module (430) in the vehicle (100), a video processing module (440) in the vehicle (100), an information splitter (514) in the motion chair (570), a motion processing unit (520) in the motion chair (570), a control unit (550) in the motion chair (570), a G-force calculation unit (560) in the motion chair (570) and a force feedback generation unit (540) in the motion chair (570). The motion processing unit (520) calculates six degrees of freedom of motions of the vehicle based on the image stabilization signals generated from the cameras (110,120). The force feedback generation unit (540) produces force feedback signals based on the six degrees of freedom of motions of the vehicle (100) and the G-force calculated by the G-force calculation unit (560).

  • Patent number: 4734035
    Abstract: An endodontic stop positioner combined with a reamer or a file used for taking a measurement of the root canal length of the tooth, includes a positioning body with a hard member and a soft member made of non-metal material, a central penetrating hole formed in the positioning body for accomodating the reamer or file, which reamer or file is movably held in the central penetrating hole for being inserted into the root canal of the tooth in taking the measurement in an X-ray, and at leat a wire disposed in a bottom center of the hard member and located in perpendicular intersection with the reamer or file. Consequently, the intersection point between the wire and the reamer or file can be clearly indicated in the X-ray for accurately measuring the root canal length of the tooth therewith.
