Abstract: A lighting device comprising a lighting module including an optical output configured to emit a light beam having an angular spread. The module has a light source configured to generate the light beam and an optical diffuser arranged to receive and diffuse the beam towards the optical output, such that the downstream value is greater than the upstream value of the angular spread. A control module emits a control signal having an alarm value when the value of the angular spread of the light beam emitted by the optical output passes below a first threshold, the control module comprising a photoreceptor optically coupled to the optical output and configured to measure a light intensity. The control module outputs the control signal having the alarm value when the value of the light intensity falls below a second threshold. A control circuit deactivates the light source upon reception of the control signal.

Abstract: The monitoring system (1) comprises: a light source (3), an image acquisition device (5) comprising a shutter (11) which allows light to pass during a period (P1) when the source is active and during a period (P2) when the source is inactive, the light received by a sensor (9) comprising a component (Ca) due to ambient illumination and a component (Ci) due to the light source; a processing unit (7) configured for determining a physiological parameter of the occupant by photoplethysmography. The shutter (11) allows light to pass during a third period (P3), said light comprising the component (Ca) due to ambient illumination and the processing unit (7) being configured for subtracting this component (Ca) from the light received (9) during the other two periods for the purpose of isolating the component (Ci) due to the source in acquired images.

Abstract: 12. A lighting device comprising a lighting module including an optical output configured to emit a light beam having an angular spread is disclosed. The module has a light source configured to generate the light beam and an optical diffuser arranged to receive and diffuse the beam towards the optical output, such that the downstream value (?2) is greater than the upstream value (?1) of the angular spread. A control module emits a control signal having an alarm value when the value of the angular spread of the light beam emitted by the optical output passes below a first threshold, the control module comprising a photoreceptor optically coupled to the optical output and configured to measure a light intensity. The control module outputs the control signal having the alarm value when the value of the light intensity falls below a second threshold. A control circuit deactivates the light source upon reception of the control signal having the alarm value.

Abstract: The present invention relates to a method of governing a system such as a vehicle screen wiping system. It also relates to a governing apparatus for performing the method of the invention, and to a governed system of the simultaneous or synchronized type, for wiping a glass surface of a vehicle.The governing apparatus according to the invention includes a low level control module which effects, in the system, a reversion to a stable state. The command signal from the low level control module is generated by an intermediate level control module which operates as an open loop. Finally perturbations are compensated for by a high level control module which produces a modification of the command signals in such a way as to render the governing action convergent. The modification of the command signals consists in reducing the rate of propagation of the command signals when the load increases.
