  • Publication number: 20160165542
    Abstract: A vehicle communication system includes a mobile terminal having a display screen in which display ON and OFF of the display screen can be operated by a user and a vehicle that performs communication with the mobile terminal in a first interval period when a connection has been established. The vehicle has an in-vehicle control unit that, before the connection is established, sends an inquiry signal for establishing the connection to a vicinity of the vehicle in a second interval period. The mobile terminal has a control section that, before the connection is established, performs scanning operation that enables the inquiry signal to be received in a third interval period. The control section can set the third interval period so as to be operational in at least two periods and sets the third interval period to the high-speed mode when the display of the display screen is on.

  • Publication number: 20160164335
    Abstract: A non-contact charger includes a position detector, a determination unit, a primary coil, a coil moving unit, and a controller. The position detector detects placement of an electronic device, which incorporates a secondary coil, onto a top plate of the non-contact charger. The determination unit determines whether the electronic device is placed onto the top plate of the non-contact charger from a lateral direction. When the determination unit determines that the electronic device is placed onto the top plate from the lateral direction, the controller instructs the coil moving unit to wait for a predetermined period of time in moving the primary coil. After the waiting for the predetermined period of time to delay the movement of the primary coil, the controller moves the primary coil toward a position of the secondary coil of the electronic device.

  • Publication number: 20160159279
    Abstract: An alert system includes a vehicle that transmits predetermined verification information within a communication range and a portable terminal that performs a predetermined alert operation on receiving the verification information. The portable terminal includes a control part that stores reference status being status of the vehicle and needing no alert operation. The control part regularly receives the verification information within the communication range. The control part determines that an alert operation is necessary when the portable terminal is moved out of the communication range from inside of the communication range and when a result of comparison between the verification information received immediately before the portable terminal is moved out of the communication range and the reference status stored in advance indicates that the verification information and the reference status are different.
