<p>Electronic device (10), suitable to provide a personal communication by local radio data transmission, characterized in that comprising:
communication means, including a radio transceiver (11) with antenna (21); signalling means including: a display (14) and an acoustic unit (16); means of user interface, including a rotary commutator with a button switch (17); power supply means, preferably made of a lithium battery with on/off switch (13); means of serial data communication, including a serial port (18) and related connector (19); controlling means, composed of a microprocessor unit (12) with memory and internal data bus (20), including through a firmware, a complete process of:
encoding and generation of a message, including a user profile to be irradiated at distance; management of said radio communication means; analysis of an input data flow and of intensity of the electromagnetic field; decoding of user profiles encoded in said input data flow, and matching with a set of user profiles internally saved; signalling of compatibility of received user profiles with the ones internally saved; management of said means of user interface; management of said means of serial data communication.</p> |
