  • Publication number: 20210089983
    Abstract: A vehicle ride-sharing assist system includes a user terminal, a vehicle terminal, and a host server. The host server includes a proximity notification unit for generating a proximity notification signal when a distance between a user and a ride-sharing vehicle becomes equal to or less than a prescribed value. The vehicle terminal includes a user response request unit for generating a user response request signal on receiving the proximity notification signal. The user terminal includes a user side notification/operation unit for notifying the user of a specific motion or cause the user terminal to perform a specific operation according to the user response request signal. The vehicle terminal further includes a user position identification unit for detecting the motion of the user or the operation of the user terminal and identifying a position of the user. A user position notification unit notifies the identified position to the driver.

  • Patent number: 8250934
    Abstract: There is provided a multi-axis force sensor including first and second bridge circuit groups detecting resistances of respective first and second groups of strain resistance elements provided at respective strain producing portions. The strain producing portions are formed on two axes intersecting with respect to each other at a right angle. The first group of strain resistance elements are arranged on one axis across an action portion so as to face with respect to each other, and the second group of strain resistance elements are arranged on another axis across the action portion so as to face with respect to each other. The first bridge circuit groups respectively output a positive voltage when receiving tensile force, and the second bridge circuit groups respectively output a negative voltage when receiving tensile force.
