Abstract: A wireless communication network system (1) comprising a sensor device (10) transmitting detected data, one or a plurality of relay devices (100) relaying the data, and a gateway device (11) transferring the data to another network, wherein the sensor device, the relay device, and the gateway device being connected by a wireless communication network, wherein the relay device comprising: a receiver (101) receiving a received signal containing the data; a storage (104) storing heartbeat data; a transmitter (102) transmitting a transmission signal containing the data received by the receiver and periodically transmitting a transmission signal containing the heartbeat data; and a frequency setting unit (103) directing to set a frequency of the received signal received by the receiver and/or a frequency of the transmission signal transmitted from the transmitter based on a frequency setting command transmitted from the gateway device.

Abstract: A touch location detection section (103) detects the location on a display screen where the operator's finger touches. A transfer length calculation section (104) calculates the transfer length La of the operator's finger from the touch start location S to the touch end location E. A transfer length judgment section (105) judges whether or not the transfer length La is greater than a reference transfer length Ls. A location shift calculation section (106) calculates the location shift ? of the operator's finger. A location shift judgment section (107) judges whether or not the location shift ? is less than a predetermined reference location shift ?s. When La>Ls and ?<?s, a screen split control section (108) controls the operation of an image display section so as to split a display screen 101.

Abstract: Herein disclosed is a display apparatus, to be mounted on an automotive vehicle, comprising: display means (4) for displaying images; supporting means (3) for linearly or pivotably supporting the display means (4); and controlling means (2) for controlling the supporting means (3) to have the display means (4) linearly or pivotably moved to ensure the display means 4 being in face to face relationship with the eyes of the passenger.

Abstract: Herein disclosed is a NOTIFICATION APPARATUS comprising a behavior detecting unit for detecting a behavior of a vehicle, a video display unit for displaying a video, an imaging unit for acquiring a video showing the front of the vehicle in a traveling direction; and a control unit for controlling a display mode of the acquired video displayed by the video display means in accordance with the behavior detected by the behavior detecting unit, thereby displaying the video taken by the imaging unit selectively in a full screen of the video display unit by an interrupt way and a split screen of the video display unit while the television picture is displayed. The notification apparatus thus constructed can enhance riding comfort of vehicle passengers even though the vehicle passengers may watch, for example, a television picture.

Abstract: It is an object of the present invention to provide an image display apparatus which can reduce a burden to be imposed on vehicle occupants by informing the vehicle occupants about current and next travel states of a vehicle while allowing the vehicle occupants to watch TV or the like in the vehicle. In the on-vehicle image display apparatus, the image controlling means controls the on-screen position of the image produced by the image producing means on the basis of the judgments made by the travel state detecting means on whether or not the vehicle is turning to the right, or about to turn to the right, whether or not the vehicle is turning to the left, or about to turn to the left, whether or not the vehicle is being accelerated, or about to be accelerated, and whether or not the vehicle is being decelerated, or about to be decelerated.
