Abstract: A method for determining the presence of a transmitter and a receiver in a vehicle by means of a central processing unit, wherein said transmitter and receiver are designed for transmitting electromagnetic or optical signals in a predetermined direction and for receiving said signals from substantially the same predetermined direction, respectively, for example for communicating between different vehicles, and wherein said transmitter and receiver are operatively connected to the central processing unit, comprising the steps of: —generation of a signal in the central processing unit; —transmission of a signal by the transmitter in dependence on the signal generated in the central processing unit; —reception by the receiver of the signal from the transmitter; and —determination by the central processing unit of the presence of the transmitter and the receiver in dependence on the signal from the receiver.

Abstract: Disclosed is a vehicle provided with at least one detector designed to detect external measuring equipment that emits laser pulses for detecting or measuring the speed of the vehicle. The vehicle is further provided with at least one glass fibre cable whose first end is fixed in front of the detector, facing said detector, and with a transparent receiving element connected to the glass fibre cable for receiving the laser pulses and passing said pulses on to the glass fibre cable. The receiving element is attached to the exterior of the vehicle and, in stretched condition, extends along a length of at least 0.25 m on the vehicle surface.

Abstract: A vehicle with a device including a central processing unit, at least one detector with at least one detection surface and designed for detecting, in a detection direction, laser pulses or a light beam coming from an external measuring apparatus which emits laser pulses or light beams for the purpose of detecting a vehicle and/or measuring the speed of a vehicle, and at least one transmitter with a transmission surface and which is designed for transmitting light pulses in a transmission direction that is substantially the same as said detection direction. The central processing unit causes the transmitter to transmit a series of light pulses upon detection of laser pulses or a light beam. The detection surface and the transmission surface are oriented substantially transversely to the driving direction of the vehicle.

Abstract: A traffic communication system comprising a laser transmitter arranged for emitting a pulsating laser signal, wherein at least one message has been encoded into the pulse sequence of the laser signal, a laser receiver arranged for receiving the pulsating laser signal, and a central processing unit arranged for determining said at least one message in the pulse sequence of the received signal and carrying out a command in dependence on the message received.

Abstract: A module electronic device, for example a car radio, a navigation system or a radar detection system, comprising a fixed module fitted with external electrical contact elements, which is to be mounted on a wall, for example a dashboard, and a detachable module fitted with electronic components and external electrical contact elements, which detachable module can be connected to the fixed module in such a manner that the external electrical contact elements of the two modules are interconnected, wherein the fixed module and/or the detachable module comprise(s) at least one magnet, such that the detachable module can be connected to the fixed module through magnetic force.

Abstract: A device for preventing a vehicle from speeding, which device comprises a switching device, a speedometer present in the vehicle, which is connected to said switching device and which measures the speed of the vehicle, as well as a transmitter connected thereto, wherein the switching device is so arranged that the transmitter will only transmit a signal mainly if and as long as the speed measured by the speedometer is higher than a predetermined limiting value.

Abstract: Device comprising a patch antenna, and coupling means for connecting the antenna to an electronic component, wherein the patch antenna is arranged on one side of an antenna plate, and the electronic component can be mounted on the other side of the antenna plate, wherein the coupling means comprise a metal passage through the antenna plate. This passage thus ensures the transmission of signals between the antenna and the electronic component. Such a passage is mechanically very robust and not susceptible to ageing, whereby this passage is suitable for automotive applications. This passage is generally not ideal, since it does not have the same characteristic impedance as the antenna and the electronic component, but the dimensions of the passage can be kept sufficiently small so that no disruption is encountered from this impedance mismatch.
