  • Publication number: 20180107946
    Abstract: From each of in-vehicle units in vehicles, a travel behavior data indicating a travel behavior of the vehicle is received and recorded in a travel history database. The travel behavior data of the vehicles are read from the travel history database; an avoidance action arising in each of the vehicles is detected based on the read travel behavior data. From the detected avoidance actions of the vehicles, a related avoidance action group being avoidance actions arising due to an identical object at different positions at different points of times in different target vehicles is extracted based on an occurrence position and an occurrence point of time of each detected avoidance action. Information on position change of the identical object as a cause of the extracted related avoidance action group is recorded as an alert target data.

  • Patent number: 9774123
    Abstract: A connector is provided with a connecting terminal, a connecting housing, and a front holder. The connecting housing includes a connecting terminal storing chamber, and a lance which is elastically deformable in order to store the connecting terminal into the terminal storing chamber and which is engageable with the connecting terminal in order to prevent the connecting terminal from removing when recovered from an elastic deformation. The front holder is supported to be movable to back and forth along the insertion direction and locked on a front end of the terminal storing chamber. The front holder is moved in the opposite direction to the insertion direction to be actually locked by pressure in a state that the front holder is temporarily locked and contacted with the connecting terminal to hold in a state that the front holder is actually locked.

  • Patent number: 9665216
    Abstract: A proximity detection unit detects the proximity of a finger to a screen and outputs a proximity detection signal. A contact detection unit detects the contact of the finger to the screen and outputs a contact detection signal. On the basis of the proximity detection signal, a display control unit magnifies and displays a predetermined range around a proximity corresponding position. On the basis of the contact detection signal depending on the contact operation of the indicator for the predetermined range, the display control unit fixes the magnified display of the predetermined range and does not change the display position of the magnified predetermined range depending on the movement operation of the finger on the screen.
