摘要:
A communication system has a first communication device, and a second communication device that conducts wireless communication with the first communication device. The first communication device has a first transmitter that transmits a signal to the second communication device, and a first transmission controller that controls the first transmitter. The second communication device has a first receiver that receives the signal from the first communication device, a measurement part that measures a reception intensity of the signal received by the first receiver, and a determination part that determines whether the signal received by the first receiver is a normal signal. The first transmission controller divides a predetermined portion of a predetermined signal into a plurality of portions when transmitting the predetermined signal.

A communication system has a first communication device, and a second communication device conduct wireless communication with the first communication device. The first communication device has a first transmitter that transmits a signal to the second communication device, and a first transmission controller that controls the first transmitter. The second communication device has a first receiver that receives the signal from the first communication device, a first reception controller that controls the first receiver, a signal processor that processes the signal received by the first receiver, and a determination part that determines whether the signal received by the first receiver is a normal signal. When transmitting a predetermined first signal, the first transmission controller divides the first signal into a plurality of segments to change a transmission frequency of the first transmitter in units of segments.

In a door control system, a reservation signal is transmitted when a user operates a mobile device and reserves opening a door, a control device transmits a reservation acceptance signal and starts transmitting a response request signal upon receipt of the reservation signal. When the mobile device receives the reservation acceptance signal, a mobile device memory stores information indicating that the reservation is accepted and authorized and a notification unit notifies the user of authorization. When the mobile device receives the response request signal, the mobile device transmits a response signal including the stored information indicating authorization. When the control device receives the response signal including the information indicating authorization in response to the response request signal, a controller performs at least one of unlocking or opening the door.

A vehicle communication system includes a vehicle-mounted device and a portable device. In the vehicle communication system, a transmission unit transmits a first to third radio signals having intensities weaker in this order, a measurement unit measures an intensity of each of the radio signals, and a determination unit that determines whether an intensity difference between any two of the radio signals among the radio signals measured by the measurement unit is larger than a threshold value. Control of a target mounted on the vehicle is permitted if the intensity difference is larger than the threshold value.

A control system includes a portable device transmitting to a proximity control signal controlling locking/unlocking of an opening/closing body of the vehicle from near the vehicle, and a remote control signal controlling an engine remotely, intensity of the remote control signal higher than the proximity control signal, and a control device receiving a signal transmitted by the portable device. The portable device transmits by a same transmission antenna the whole of the proximity control signal at a single center frequency, and all of divided signals obtained by dividing the whole of the remote control signal into plural pieces at plural center frequencies. The control device receives by a same reception antenna the whole of the proximity control signal at the single center frequency, and all of the divided signals at center frequencies corresponding to frequencies used upon transmission of the divided signals by the portable device.
摘要:
A vehicle control apparatus includes: a vehicle-mounted transmitter which transmits a first response request signal; a vehicle-mounted receiver which receives, from a portable device, a response signal to the first response request signal; and a controller which allows an operation for welcoming a user carrying the portable device to a vehicle according to a reception state of the response signal. When intermittently transmitting the first response request signal at predetermined intervals via the vehicle-mounted transmitter, the controller determines whether condition set in advance is established. When the condition is established, the controller transmits a second response request signal different from the first response request signal. According to whether the vehicle-mounted receiver receives, from the portable device, a response signal to the second response request signal, the controller stops transmission of the second response request signal and then suppresses transmission of the first response request signal.

It is an object of the present invention to move a viewpoint position and a direction of a line of sight a player character with an intuitive operation method without requiring pre-study. In a case where a player touches a point within a movement determination region, a virtual 3D spatial image moved forward in the direction of the line of sight is displayed. In a case where a player touches a point at the left side outside the movement determination region, a virtual 3D spatial image as viewed by a virtual camera panned to the left is displayed, whereas in a case where a player touches a point at the right side, a virtual 3D spatial image as viewed by a virtual camera panned to the right is displayed. Furthermore, in a case where a player touches an upper point, a virtual 3D spatial image as viewed by a virtual camera tilted in the upper direction is displayed, whereas in a case where a player touches a lower point, a virtual 3D spatial image as viewed by a virtual camera tilted in the lower direction is displayed.
