A detection and communication module arranged to implement a face detection function and an optical wireless communication function, and including a processing unit, a transmission chain and a reception chain, the processing unit being arranged to transmit via the transmission chain a detection signal, to receive via the reception chain the detection signal following its reflection on a face surface of an individual, and to evaluate a distance between the detection and communication module and the face surface of the individual, the processing unit being further arranged to transmit via the transmission chain a transmitted optical wireless communication signal containing data to be transmitted, and to receive via the reception chain a received optical wireless communication signal.

Face detection and optical wireless communication module

A lighting and communication system includes a first optical fiber portion, a second optical fiber portion, a third optical fiber portion, a fourth optical fiber portion and a fifth optical fiber portion that are distinct, wherein a visible light transmitter is positioned at a first end of the first optical fiber portion, a modulated light signal transmitter is positioned at a first end of the second optical fiber portion, a second end of the first optical fiber portion and a second end of the second optical fiber portion are connected to a first end of the third optical fiber portion, a modulated light signal receiver is positioned at a first end of the fourth optical fiber portion, a second end of the third optical fiber portion and a second end of the fourth optical fiber portion are connected to a first end of the fifth optical fiber portion.

Lighting and communication system comprising a transmitter and a receiver of modulated light signals

An insulation device arranged to be fixed on an electrical board of an optical wireless communication equipment, and including an enclosure having a height at least equal to a height of an optical assembly including an optical concentrator, the enclosure including in its thickness an opaque material, the insulation device including at least one housing, the insulation device being arranged such that, when the insulation device and the optical assembly are mounted on the electrical board, the enclosure surrounds the receiving surface so as to insulate the optical assembly from unwanted optical signals, and the optical concentrator is positioned in the housing so that the housing assists in holding the optical concentrator in position in the optical wireless communication equipment.

Insulation device incorporated in an optical wireless communication equipment

An optical wireless communication device includes a processing component which is configured to produce transmitted digital signals during transmission periods; a light source which is configured to produce transmitted light signals from transmitted analog signals; a shutdown circuit which is configured to selectively activate or deactivate the light source; the processing component including a binary output to which it applies a binary control signal which is in a first state during the transmission periods and in a second state outside the transmission periods, the shutdown circuit being configured to activate the light source when the binary control signal is in the first state and to deactivate the light source when the binary control signal is in the second state.
