Title: System for detecting (collecting) traffic information in vehicles
Inventor: GEDULD GEORG OTTO
IPC: G08G1/0967
Filed: 1994-04-21
Granted: 1995-04-06
Abstract: The invention concerns traffic information acquisition systems for vehicles, which systems have a first opto-electrical transceiver on the vehicle side and a second opto-electrical transceiver provided at predetermined locations in traffic lanes. The first transceiver emits a first signal and receives and decodes a second signal from the second transceiver. The second transceiver receives the first signal from the first transceiver and sends back a coded, second signal to the first transceiver. The first transceiver is in the form of a reflection-operating time-distance measuring device. The emitted optical distance-measuring pulse signal is simultaneously the signal received by the second transceiver. The second transceiver emits the second signal after a delay time following reception of the first signal. The delay time should be longer than the maximum amount of time required for a distance measurement. It is thereby ensured that a signal from the second transceiver is not erroneously interpreted as a signal reflected by a target.

Title: Visually identifiable optical security element for credit cards etc.
Inventor: REINHART WERNER
IPC: B42D25/00
Filed: 1994-09-09
Granted: 1995-11-30
Abstract: A visually identifiable optical element, in particular a safety element for securities, such as bank notes, credit cards, identity cards or checks, or other objects that need to be safeguarded, has a substrate with a diffuse reflecting visible surface and a metallised layer applied on certain areas of the visible surface (12, 34) of the substrate (10, 28, 36). The surface of said metallised layer has a metallic brilliant appearance when observed from a certain angle. In order to improve such an optical element so that objects provided therewith are even better protected against forgery than is possible with known optical elements, two areas (14, 16, 30, 32, 40, 42) of the visible surface (12, 34) of the substrate have different reflectivities, in particular diffuse reflectivities for light. One part (18, 24, 26) or several parts (38) of each of the two substrate areas (14, 16, 30, 32, 40, 42) are metallised. Observed from directions outside a viewing range, the metallised parts have a reflectivity that is lower than or substantially equal to the reflectivity of the most reflective substrate area and higher than or substantially equal to the less reflective substrate area.
