Abstract
Abstract A signaling and/or help request system. A remote transmitter transmits an alarm signal which is received by a receiving/convening device which cooperates with the transmitter. The receiving/conveying device is fitted to a street lamp to transmit a message including an identification code to the electrical supply means. a receiving unit connected to the supply means extracts the messages supplied by the receiving/conveying device and supplies them through a network to a centralized receiver to generate a help request output signal.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
107 words
A signaling and/or help request system comprising: a remote transmitter for transmitting an alarm signal; a receiving/conveying device cooperating with said transmitter and fitted to a lamp of a public lighting system to generate a message including an identification code; a communications network for transmitting the messages generated by said receiving/conveying device; and a centralized receiving device connected to said communications network and for receiving the messages transmitted by said receiving/conveying device, and generating an information and/or help request output signal; wherein, said receiving/conveying device comprises a receiving element for receiving said alarm signal; and a conveyed-wave transmitting device for transmitting said message onto electricity supply mains.
Claim 2
Dependent Claim
107 words
