Ring or jewel assembly with radio frequency transceiver and/or radio frequency remote control function

A ring or jewel assembly with radio frequency transceiver function, comprising:

• a metal body of the ring or jewel;
• a cavity in said body of the ring or jewel, filled, at least in part, by one or more portions including at least one dielectric material;
• a radio frequency transceiver microelectronic device, configured to transmit and receive radio frequency signals, with a spectrum belonging to a predefined radio frequency range, said microelectronic device being fixed on the ring or jewel, at least partially inserted in said cavity, and at least partially surrounded by said at least one dielectric material;
• wherein said at least one dielectric material is interposed between the metal of the body of the ring or jewel and the radio frequency transceiver microelectronic device, to prevent the radio frequency transceiver microelectronic device from being in contact with the metal of the ring or jewel, and to form a space of dielectric material, adapted to allow propagation of electromagnetic signals having a spectrum in said radio frequency range;
• wherein said radio frequency transceiver microelectronic device is a passive transponder or tag, operating at radio frequency;
• wherein said passive transponder or tag is configured to interact with an external RF antenna, adapted to emit an activation signal, so that, when the ring or jewel assembly approaches said antenna below a predefined operating distance, the transponder or tag is activated after receiving the activation signal;
• wherein the transponder or tag, once activated, is configured to emit one or more predefined radio frequency signals corresponding to one or more predefined commands;
• and
• wherein the transponder or tag is configured to perform functions of a remote control for an automobile, and is adapted to interoperate, to carry out one or more commands or functions, with one or more active RFID devices, arranged in respective positions within the automobile, each active RFID device comprising an RF antenna connected to a respective active reader.
