A proximity measuring apparatus (70) comprises an interrogator (80) for generating an interrogation signal encoded with a reference signature code comprising concatenated codes and emitting it as interrogating radiation. It also incorporates a transponder (90) for receiving the interrogating radiation, demodulating it to extract its signature code and then remodulating it after a delay period to provide a signal for reemission as return radiation therefrom. The interrogator (80) receives return radiation at its antenna (260) and demodulates it to extract its signature code and then correlates the code with the reference code to determine mutual correlation thereof. The interrogator (80) incorporates a computer (290) for controlling a scan direction of the antenna (260) and for measuring time delay between emission of the interrogating radiation therefrom and receipt of corresponding return radiation. The computer (290) computes distance and relative bearing of a transponder (90) providing the return radiation from the scan direction and the time delay. The apparatus (70) may be used for improving road vehicle safety.

Disclosed is a method and apparatus for determining the risk of an object collision. The method includes transmitting a signal and analyzing a received signal that is indicative of the presence of a remote object. The signal is then analyzed to determine an initial azimuth value and an initial range for the remote object. Subsequent received signals are continuously analyzed to continuously determine subsequent azimuth values, azimuth value velocities and accelerations, as well as subsequent range values, range value velocities and range value accelerations. The factors are then input into a predetermined formula to yield a risk assessment of collision P. The formulas for determining P can be adjusted to account for such factors as number and proximity of remote objects, as well as the speed and maneuverability of both the remote objects and the vehicle that is avoiding collisions with the remote object(s).

Commissioning a coded light source in a lighting system is accomplished by using a remote controller. When an identification of a light source is successful, a control message is sent to that light source to at least partly switch off its light emission. Thus the light contribution of the identified light source is suppressed. Thereby the chance of coded light from an already identified light source colliding with identifiers comprised in coded light emitted by other light sources is reduced. When no more coded light is detectable, a sensitivity of the remote controller can be increased until coded light again is detectable. Further light sources can then be identified and commissioned.

In an inter-vehicle control apparatus, a controller performs acceleration control of an own vehicle, based on an actual inter-vehicle physical quantity and a target inter-vehicle physical quantity. A limiter sets a limit value for a target jerk during the acceleration control. A detector detects an occurrence of at least one of: an event in which the inter-vehicle distance becomes discontinuously shorter; and an event in which a target inter-vehicle distance corresponding to the target inter-vehicle physical quantity becomes discontinuously longer. A determiner determines a risk of collision with the preceding vehicle, based on an operation state of the preceding vehicle in relation to the own vehicle. When at least one of the events is detected, the limiter sets the limit value to a value based on the risk of collision such that change in deceleration of the own vehicle is kept lower as the risk of collision decreases.
