Abstract: The present description concerns an electronic device having an antenna configured to receive a radio frequency signal. The electronic device further includes a control unit. The control unit is off, and the antenna receives a radio frequency signal. The antenna is configured to deliver a first voltage representative of the radio frequency signal to power the control unit with the voltage for the duration of the booting of the control unit.

Abstract: A first object and a second object are movable in relation to one another. The first object includes a transponder using an integrated circuit having two terminals which may or may not be shorted. The presence or absence of a short circuit between the two terminals is detected. This is accomplished at least partly by the second object depending on the relative positioning of the first and second objects. The transponder transmits, to a module having a contactless reader function, positioning information corresponding to said relative positioning using a contactless communication protocol.
