SYSTÈME DE COMMUNICATION D'UNE PRÉSENCE D'UN DISPOSITIF PAR LE BIAIS D'UNE SOURCE DE LUMIÈRE

摘要

A system (100) for communicating a presence of a device via a light source (110) configured to emit light comprising an embedded code is disclosed. The system (100) comprises: a controller (102) comprising: a receiver (106) configured to receive a response signal from a first device (120), which response signal comprises an identifier of the first device (120), and which response signal is indicative of that the embedded code has been detected by the first device (120), and a processor (104) configured to correlate the embedded code with the identifier of the first device (120), such that the embedded code is representative of the identifier of the first device (120).
