The camera has an electronic sensor, a multifocal, particularly bifocal optical device, an optical lens focused in long-range field, the multifocal optical device and the optical lens being set up to be able to form a first image (IM1) on the sensor, focused in long-range field, and a second image (IM2) focused in close-range field, these first and second images extending into respective distinct regions of the sensor.
Abstract: A disengageable cylinder for a motor vehicle lock mechanism includes a fixed stator, a sleeve, a rotor, a driver, and an indexer. The sleeve is mounted in rotation about its axis in the stator, and is fixed axially with respect to the stator. The rotor is mounted in rotation in the sleeve and is fixed axially in the sleeve. Further, the rotor includes tumblers which can move radially under the action of a key intended to be inserted axially into the rotor. The driver provides a coupling between the rotor and a cam actuator, when the key is appropriate. The indexer can move axially between rest and disengagement positions and is under the effect of a rotation of the sleeve with respect to the stator subsequent to the rotor being rotated by means of an inappropriate key.

Abstract: The invention proposes a method and an arrangement for evaluating sensor images of an image-evaluating environment recognition system on a carrier, in which, in order to distinguish the light conditions in the area of the image-evaluating environment recognition system with regard to day or night, at least the gain and/or the exposure time of the at least one image sensor detecting the environment is/are monitored, a profile of the gain and/or the exposure time against time with relatively high gain or relatively long exposure times characterizing night-time light conditions, and a profile of the gain and/or the exposure time with relatively low gain and/or relatively short exposure times characterizing daytime light conditions. The environment recognition system according to the invention can also be used to search the detected environment for bright objects, the headlights of another carrier being used as additional information, for example.
Abstract: The claw-pole-rotor shaft has a front end with a radially larger-sized section, two knurled regions known as crimping regions, intended to be assembled with the claw-pole rotor by local deformation of the material of the claw-pole rotor, and a centring region for centring the claw-pole rotor, the crimping regions being positioned on each side of the centring region while the centring region projects radially with respect to the crimping regions of the shaft, these themselves projecting radially with respect to the section of larger radial size at the front end of the shaft. The claw-pole rotor is characterized in that it is equipped with such a shaft while the rotary electrical machine is characterized in that it is equipped with such a rotor.

Abstract: A disengageable cylinder for a motor vehicle lock mechanism includes a fixed stator, a sleeve, a rotor, a driver, and an indexer. The sleeve is mounted in rotation about its axis in the stator, and is fixed axially with respect to the stator. The rotor is mounted in rotation in the sleeve and is fixed axially in the sleeve. The driver is connected in translation on the rotor. The indexer, which can move axially between rest and disengagement positions, is connected in translation on the stator. When an appropriate key is inserted in the rotor, the driver couples the rotor and a cam actuator in rotation, releasing the lock. When an inappropriate key is inserted, the rotor and sleeve rotate, causing the indexer to move toward the cam actuator. Because the indexer is rotationally immovable as a result of its connection with the stator, the cam actuator cannot rotate.
