A method for authentication between a control module and a lighting module for a motor vehicle, in which at least one of the two modules is a transmitter module, the other being a receiver module, the two modules comprising a unit for transmitting/receiving data and being linked by a data communication channel that enables the modules to exchange data. The method including transmitting of data describing at least one authentication factor from the transmitter module to the receiver module, verification of the authentication factor by means of a calculation unit, and abandoning communication, in the receiver module, with the transmitter module if the verification fails, or otherwise continuing communication.

Lighting module for a motor vehicle comprising a matrix light source grouping together a plurality of elementary light sources, and a control module for a motor vehicle. Method for controlling the matrix source of said module, noteworthy in that it allows a default lighting setpoint to be generated.

A vehicle headlamp alignment system is provided that includes a headlamp located on a vehicle, an adjuster module for adjusting aim of the headlamp, and a camera located on the vehicle. Sensors may determine distance and orientation of the vehicle relative to a wall. A controller processes images of a beam on the wall acquired by the camera and determines the aim of the headlamp based on the images. The controller controls the adjuster module to align the headlamp based on the determined aim.

A system for monitoring a trailer having a plurality of light emitting diode devices includes a master control unit attached to an outside surface of the trailer. The master control unit includes a solar panel, a GPS receiver module, a cellular data transceiver module for communicating with a central tracking computer via a cellular data network interfaced to the Internet, and a local wireless network master transceiver module in wireless communication with a plurality of wireless sensors and a light out detection system. A microcontroller is provided for controlling the local wireless network master transceiver module to periodically obtain sensor data from the wireless sensors and light out detection system, and for controlling the cellular data transceiver module to transmit the location and the sensor data to the central tracking computer for storage in the tracking database.

At least one processor of an electronic device in a vehicle may be configured to: receive broadcast information which is broadcast from a beacon and includes reference data indicating the relative positional relationship between a designated object positioned in a designated place and the position of the beacon and the data of the designated place; in response to reception of the broadcast information, acquire sensed data indicating the relative positional relationship between the designated object and the vehicle through at least one sensor of the electronic device on the basis of the data of the designated place; in response to acquiring the sensed data, identify the difference between the sensed data and the reference data; identify whether the difference lies outside of a reference range; and determine correction of the at least one sensor to be required, on the basis of identification that the difference lies outside of the reference range.

The invention relates to a signalling device (1) designed to be removably placed on the back of a user of a locomotive engine, the device (1) including electronic means for signal processing and for controlling the switching-on and/or switching-off of the at least one secondary signal light (3d, 3g) synchronously with the switching-on and/or switching-off of a primary signal light present in the machine. Electronic means are built into an accelerometer and means for interpreting measurements of the accelerometer allow the detection of a lateral variation, to the right or left, of the direction of movement, the means for controlling the at least one secondary signal light (3d, 3g) comprising means for verifying that the at least one secondary signal light (3d, 3g) indicates the lateral right or left direction followed by the user and the machine.

The present invention relates to a lamp system including a digital micro-mirror device (DMD) module, and more particularly, to a system and method for improving life characteristics of a DMD module. A DMD lamp and a method of controlling a DMD lamp of the present invention may improve a life of a DMD module by measuring a temperature of the DMD module in real time and controlling operations of the DMD module and a light source when the temperature of the DMD module rises above a certain temperature, and improve the life of the DMD module by adjusting a ratio of an ON mode/OFF mode of the DMD module to the same ratio and automatically compensating for the insufficient amount of light to reduce the consumption of an angle adjusting unit of a mirror to a minimum while maintaining the output amount of light.

An aircraft beacon light with integrated health monitoring comprises an annular arrangement of light sources, which are configured for repeatedly emitting beacon light flashes; a light detection sensor surrounded by the annular arrangement of light sources; and at least one reflective portion arranged to reflect light emitted by the annular arrangement of light sources onto the light detection sensor.

An adaptor for connecting an LED lighting unit to a vehicle CAN-bus. The adaptor has a connector connectable to a corresponding connector on a vehicle, to receive a lighting current from the CAN-bus of the vehicle. A wireless power transmitter of the adaptor wirelessly transmits power to the LED lighting unit at a first level, typically suited to LED operation. The adaptor further includes one or more resistors connected between the connector and transmitter and arranged to draw power from the connector at a second power level higher than the first power level, which second power level is suitably equivalent to that for halogen or filament lighting.

A monitoring system for a combination vehicle comprises at least one image capture device mounted on a tractor, which has a trailer mounted control system within its field of view. The trailer mounted control system has a visual indicator. A controller is associated with the at least one image capture device. The controller captures images of the visual indicator, determines if the visual indicator meets a predetermined event condition and provides notification to at least one of a driver of the tractor and a remote fleet operator in response to the visual indicator meeting the predetermined condition.
