Title: Method of analysing sequences of road images, device for implementing it and its application to obstacle detection
Inventor: RABOISSON STEPHANE
IPC: G06T5/00
Filed: 1991-03-22
Abstract: The method of analysis of sequences of road images taken by a camera installed on board a moving vehicle, combines an analysis (130, 131, 132) of the luminance signal, from which contours are extracted, and an analysis (110) of the colour video signals taking into account the fact that the colorimetric components of a road area in an image contain no green nor red dominant, in order to confirm the limits of the road in the image on the basis of the contours, with a good reliability. A mask of the road is then set up by filling. This method is applicable especially to the detection of obstacles on the road followed by a vehicle, and the information which it generates can be combined with the information originating from other detector means in an obstacle detection system applicable to motor vehicle traffic.

Title: Appts. to anticipate signalling of braking of vehicle - uses photodetector mounted on brake pedal and facing light source mounted under dashboard to activate rear warning lights
Inventor: JEAN-CLAUDE DOMENECH
IPC: B60Q1/44
Filed: 1992-09-02
Abstract: The braking indicator which anticipates signalling of braking of a vehicle, detects the movement of the driver's foot toward the brake pedal and activates a warning signal. A photodetector is placed on the brake pedal facing a light emitter that is mounted under the dashboard. The light emitter is positioned so that its light falls on the photodetector until the driver moves his foot toward the brake pedal and interrupts the light beam. The activation triggers a circuit that flashes the stop lamps at the rear of the vehicle. USE/ADVANTAGE - Gives earlier warning of vehicle braking, reducing risk of rear-end collisions.

Title: Rock crusher with heavy moving hammers known as "bulldozer" with reduced speed
Inventor: PIERRE BELIN JEAN
IPC: A01B27/00
Filed: 1993-06-03
Abstract: Device for braking, crushing, and fragmenting oversized stones. The invention relates to a device which consists, under the effect of the rotation of the rotor (15) equipped with moving hammers (6), (7) and (8) at its periphery, in breaking up the stones for a first time under the action of these hammers, which stones are then driven towards the pre-anvil (1) under the effect of the rotation of the rotor.
