  • Patent number: 10697780
    Abstract: A position correction device includes: a reception unit, a position acquisition unit, a determination unit and a position information transmission unit. The reception unit receives a position information S1 of a vehicle from a navigation apparatus. The position acquisition unit acquires a position information S2 of the vehicle with a higher accuracy than the navigation apparatus. The determination unit determines whether a difference between the position information S1 and the position information S2 exceeds a predetermined threshold, or determines whether a traveling road identified by the position information S1 matches a traveling road identified by the position information S2. At least when it is determined that the difference exceeds the threshold, or when it is determined that the identified traveling roads do not match, the position information transmission unit transmits the position information S2 to the navigation apparatus.

  • Publication number: 20200073497
    Abstract: An input device includes a sensor unit, an optical layer superimposed on the sensor unit, and a flexible wiring substrate having a connection region held between the optical layer and support base member. The flexible wiring substrate has a flexible base member on which an electrode layer is provided and a wiring end that is an end of the electrode layer and is conductive with the terminal part with a conductive joining member. The wiring end is set back from an end of the flexible base member, so that the flexible base member has a protruding part protruding toward the sensing region. Since the input device has, on the sensing region side relative to a front end of the protruding part, a part into which the conductive joining member does not stick out, an air bubble region between the sensor unit and the optical layer can be narrowed.
