SYSTEM FOR TRANSMITTING AN ALERT
First Claim
1. An apparatus comprising a system for transmitting an alert even in the absence of a cellular network, said system comprising a walkie-talkie configured to be carried by a first human being, wherein said walkie-talkie comprises a radio-electric transmitter-receiver and a loudspeaker, wherein said radio-electric transmitter-receiver is configured to listen directly to a channel used to exchange audio signals alternately with other walkie-talkies, and wherein said loudspeaker is configured to transmit said audio signal received on said channel used to exchange audio signals alternately with other walkie-talkies into a voice message directly perceivable by said first human being, and an alert beacon that can be carried, during an outdoor activity, by a second human being, wherein said alert beacon comprises a geo-location module and a transmit circuit, and wherein said transmit circuit comprises a memory and a microcontroller, wherein said geo-location module is configured to generate coordinates, in the form of a succession of numerical symbols, corresponding to a current position of said alert beacon on the terrestrial surface with a resolution of less than 500 meters, wherein said transmit circuit is configured to produce an alert signal containing said generated coordinates and to transmit said produced alert signal as an audio signal on said channel, wherein said memory contains, for each symbol of said generated coordinates, an audio transcription of said symbol, wherein said microcontroller is configured to introduce, into said alert signal produced, audio transcriptions recorded in said memory, and wherein said audio transcriptions correspond to each symbol of said generated coordinates in such a way that said generated coordinates can be played back in the form of a voice message directly perceivable and comprehensible to a user of any walkie-talkie that has received said message on a channel that is being listened to.

Abstract
An alert beacon carried directly by a human being is equipped with a transmit circuit able to produce an alert signal transmitted on the same channel as that used by a walkie-talkie. The transmit circuit has a memory containing, for each symbol of the coordinates of the current position of the alert beacon, an audio transcription of the symbol, and a microcontroller able to introduce, into the alert signal produced, the audio transcriptions recorded in the memory corresponding to each symbol of the coordinates in such a way that the coordinates can be played back in the form of a voice message comprehensible to a user of any walkie-talkie that has received this message on a channel that is being listened to.

- 4. An apparatus comprising an alert beacon configured to be carried directly by a human being during an outdoor activity, said alert beacon comprising a geo-location module configured to generate coordinates in the form of a succession of numerical symbols, said coordinates corresponding to a current position of said alert beacon on the terrestrial surface, with a resolution of less than 500 meters, and a transmit circuit configured to produce an alert signal containing said generated coordinates generated and to transmit said alert signal produced, in the form of an audio signal on the same channel as that used by a walkie-talkie, wherein said transmit circuit comprises a memory containing, for each symbol of said generated coordinates, an audio transcription of said symbol, and a microcontroller configured to introduce into said alert signal, said audio transcriptions, recorded in the memory, corresponding to each symbol of said generated coordinates in such a way that the generated coordinates can be played back as a voice message directly perceivable and comprehensible to a user of a walkie-talkie that has received said alert signal on a channel that is being listened to.
