A timepiece including a case formed of a metal middle part wherein are disposed a metal dial and a remote communication system provided with a multi-band antenna device arranged above the dial, the communication system including a bracelet of the timepiece connected at its ends to the middle part and including a body formed of a plurality of fastening elements having different electrical conduction properties, the arrangement of the fastening elements in the body of the bracelet being configured to achieve an enlargement of the radiation pattern of the antenna device.

Antenna device

An antenna device intended to be used in a communication system of a timepiece, including a substrate; a first antenna circuit made on the substrate and having first and second strands which are connected and having a proximal end and a distal end, extending in parallel, a second antenna circuit made on the substrate and having third and fourth strands which are connected and having a proximal end and a distal end, and extending in parallel, an electrical junction link joining the proximal ends of the first and third strands; a connection portion configured to be bent relative to the electrical junction link, and including a conductive connection which is connected to the electrical junction link and including an electromagnetic shielding of the conductive connection.

Antenna device for timepiece

A method for providing information about a mechanical wristwatch, including the following steps, performed by the wristwatch: harvesting an intermittently available external energy, storing the harvested energy, at the end of a predefined period of time, generating an analysis report on an activity of the owner of the wristwatch, based at least on the times and durations of availability of the external energy, when or after the harvested energy quantity reaches a threshold, the threshold being on or above an energy level required to power a transmission unit of the wristwatch, wirelessly transmitting the analysis report to a distant reader with the transmission unit.

Method for providing information about a mechanical wristwatch

A transmitter-receiver includes an electronic chip a mixer for mixing the frequency of a received radio frequency signal with that of an oscillating signal supplied by a first frequency synthesizer in, a switch having two inputs connected to an output of the mixer and to an auxiliary input terminal, a filter and gain stage connected to the output of the switch, and a modulator-demodulator connected to the output of the filter and gain stage. The first frequency synthesizer is connected between the output of the modulator-demodulator and radio frequency input and output terminal, and configured to supply a frequency-modulated signal to the radio frequency input and output terminal. The electronic chip further includes a second frequency synthesizer connected between the output of the modulator-demodulator and an auxiliary output terminal, and configured to synthesize a modulated low-frequency signal supplied by the auxiliary output terminal, whereby the center value of the low frequency is equal to the value of the intermediate frequency.

Transmitter-receiver comprising an electronic chip

A transponder-based module is placed on a mobile object so as to transmit information in proximity to a reading device. The transponder-based module includes at least one energy source for supplying the transponder-based module, at least one sensor for performing measurements of a physical parameter, and a microcontroller linked to the measurement sensor for processing the measurements of the sensor. The module further includes a memory unit for storing the measurement data of the measurements performed by the sensor, a receiver of an interrogation signal from a reading device in proximity, and a transmitter for transmitting measurement data stored at ultra-high frequency and at very high bitrate subsequent to the reception of an interrogation signal from the reading device in proximity.
