Abstract:
The invention concerns a device for detecting the handling of at least one object, the device including a deformable enclosure, to which are attached at least one sensor for the detection of a grasping of objects and at least one wireless radio transmitter, the sensor being able to provide either one from among a first signal for detection of the grasping of an object and a second signal for detection of the absence of grasping of an object. The invention is characterized in that the transmitter includes first means for wireless radio transmission of a third signal, allowing determination of a localization of the enclosure towards a receiver remote from the deformable enclosure, as well as second means for wireless radio transmission of the first or second signal towards said receiver.
Abstract:
The invention relates to a device for transmitting an ultra-wideband-type signal, the signal including, one after the other temporally, a synchronization header and a data payload field. The transmission device includes a first generator to generate first synchronization header symbols and a third generator to generate third data payload symbols. The transmission device further includes a time sequencing device for sequencing the first and third symbols in a sequence of symbols, successively including the first symbols in the synchronization header and the third symbols in the data payload field. The transmission device further includes at least one antenna, capable of transmitting the signal ncluding the sequence. The transmission device additionally includes a fourth generator to generate at least one fourth secret symbol, the time sequencing device being configured to insert the at least one fourth secret symbol into the sequence of symbols.
