ROTATION-ACTIVATED ELECTRONIC COMPONENT
First Claim
1. An electronic device comprising:
- communication means adapted to interact with an external device;
a power source;
a component adapted to process first information received from the communication means and to send second information to the communication means, the second information being intended for the external device; and
a switch adapted to enable communication via the communication means whenever it is subjected to predetermined rotational speed and disable communication via the communication means whenever it is not subjected to predetermined rotational speed.

Abstract
A rotation-activated electronic component, preferably a RFID tag mounted on or incorporated in a support that is rotated when read, e.g. a CD or DVD. The RFID tag comprises an antenna, a rotational switch and a component, advantageously a processor. The antenna is adapted to transform received RFID signals to electric energy that powers the component. In a preferred embodiment, the rotational switch is adapted to cut the circuit unless the support does not rotate at or above a certain rotational speed. Supports equipped with the RFID tag of the invention will thus respond only if they rotate sufficiently. This can avoid collisions in case more than one such RFID tag is within communication range of an antenna of a reader. In a preferred embodiment, the information returned by the component is needed for full use of the content on the support.
