Abstract: The invention relates to a flight time sensor (10) comprising:—a lighting device (11) comprising a light source (12) which emits a source beam (13) in the direction of a scene (3) comprising an object (4) which is capable of reflecting the source beam;—a detector (15) comprising a matrix (16) of photo-sensitive pixels (16A) which receive a portion (18) of the source beam reflected by the object; and—an electronic unit (19) which is configured:—to generate a modulation signal and to control the device by means of this signal so that the source beans has a source light power which is modulated temporally;—to process electric signals which are supplied as a function of time by the detector, each electric signal representing a fraction of the source light power reflected in the direction of a pixel; and—to deduce from the electric signals a characteristic distance (Dobj) between the object and the device. According to the invention, the unit is configured, when the object is detected as being at a characteristic distance smaller than a predetermined threshold distance, to control the device in order to reduce the average source light power.

Abstract: A method for generating a virtual rendering includes receiving first image data that includes a plurality of images. Each image of the plurality of images may correspond to an environment of a non-virtual object. The method also includes determining a current position of a light source relative to the non-virtual object, determining a current intensity value of the light source, and generating a virtual rendering of the non-virtual object using the plurality of images, the current position of the light source relative to the non-virtual object, and the current intensity value of the light source. The method also includes providing, at a display, the virtual rendering.

Abstract: The disclosure notably relates to for determination of the altitude of a moving vehicle based on GNSS data and vehicle sensor data. The method comprises, in real-time obtaining a sensor vehicle pitch rate stemming from at least one vehicle sensor. The method also comprises, in real-time, while the GNSS signal is available, obtaining a GNSS vehicle pitch rate that stems from GNSS data of an altitude of the vehicle. The method also comprises, in real-time, calibrating the sensor vehicle pitch rate based on the GNSS vehicle pitch rate, the calibration being based on formulating the GNSS vehicle pitch rate as an affine function of the sensor vehicle pitch rate.

Abstract: A control system is for a motor vehicle to be driven according to a manual mode or according to various levels of driving automation by an automated driving module. The control system includes a driving assistance device and a steering control member. The steering control member includes at least one indicator light and the driving assistance device changes the status of the at least one indicator light when the driving assistance device determines an available level of driving automation, detects an active level of driving automation, determines as a function of the road configuration that the motor vehicle should be driven by the driver, and detects a switch between a level of driving automation and the manual mode.

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 (θ2) is greater than the upstream value (θ1) 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 provides a microphone assembly having shielding function for a motor vehicle, comprising: a microphone circuit board having a microphone, which is supplied by a differential audio bus such that the ground potential of the microphone is floating; a cover which is located outside the microphone circuit board; a foamy part which is located between the cover and the microphone circuit board; and a shielding film which is suitable for shielding the microphone against electrostatic discharge, wherein the shielding film is located between the cover and the foamy part and covers the outer surface of the foamy part, and wherein the shielding film is electrically conductive and grounded to a vehicle chassis ground potential. In this situation, the shielding film can collect electrostatic charges and guide them to the chassis ground of the vehicle, so that electronic components on the microphone circuit board under the shielding film, especially the microphones having the floating ground, can be shielded from electrostatic discharge (ESD) damage. As a result, the ESD robust performance of the microphone assembly is significantly improved.
