A radio wave sensor includes: a transmission antenna that emits a radio wave toward a presence allowable area which is an area in which an occupant can be present in an area in a vehicle interior of a vehicle; and a reception antenna including a plurality of reception antenna elements that receives a reflection wave of the radio wave emitted from the transmission antenna. The positions where the plurality of reception antenna elements are arranged in a vehicle width direction of the vehicle are different from each other.

Radio wave sensor and occupant detection device

A receiving unit () receives pieces of request information indicating pieces of information requested by in-vehicle devices (A toD) of vehicles (A to D) and pieces of condition information indicating the internal and external conditions of the vehicles (A to D). A delivery control unit () sets priorities for information transmission for types of respective pieces of information indicated by the pieces of request information and for the internal and external conditions of the vehicles (A to D) indicated by the pieces of condition information, and determines a transmission schedule for transmitting pieces of information to the in-vehicle devices (A toD), on the basis of the priorities. A transmitting unit () transmits the pieces of information to the in-vehicle devices (A toD), according to the transmission schedule.

Information provision system, server, and information provision method

A video delivery apparatus includes: a division unit to divide video information corresponding to one screen, which is to be delivered to each of multiple display modules constituting a display, into pieces of video information each corresponding to the number of output lines, which is N times (N is an integer of one or greater) a line indicating pixels per one line of the corresponding display module, and output the pieces of video information corresponding to the number of output lines for each of the multiple display modules; and a delivery processor to deliver the video information corresponding to one screen of the display by repetitively delivering, to the multiple display modules, delivery data obtained by multiplexing the pieces of video information corresponding to the number of output lines of the respective multiple display modules, output from the division unit, and control information indicating the target display modules to which the pieces of video information corresponding to the number of output lines are to be delivered respectively. Thus, it is possible to reduce the size of a memory held by a display controller.

Charge guidance apparatus and onboard navigation system

In UWB communication based on an MB-OFDM communication scheme, when a jamming interference is detected within a receiving frequency band, the frequency of a local signal LO is altered to a frequency that will cause the jamming to be converted to a frequency outside the pass band of an LPF.

Radio communication apparatus

Individual radio sets-constituting an onboard radio communication system operate together with an adjacent vehicle detection unit (ultrasonic sensors-) for detecting a second vehicle adjacent to a first vehicle. When it detects the adjacent vehicle, a radio interference decision unit constituting the radio sets-decides radio interference due to an onboard radio communication system with the same radio scheme. When it detects the radio interference, a frequency channel switching unit constituting the radio sets-switches the frequency channel to be used to avoid the interference of the radio waves.
