Benefits of technology

[0009]An object of the invention is to propose means enabling signals to be transmitted while minimizing any recourse to wired connections and while providing improvements concerning the above-mentioned drawbacks, at least in part.
[0016]The electrical signal may be a direct current (DC) signal or an alternating current (AC) signal, and it may be a control signal or a data signal. By way of example, the signal may be modulated in order to transmit data and the field is thus itself modulated in corresponding manner. Simple demodulation in the second apparatus thus makes it possible, after picking up the electrical signal, amplifying it, and possibly shaping it, to recover the data contained therein.

Problems solved by technology

These cables are integrated as thoroughly as possible in the garment, however they project beyond it (e.g. the cable going to the helmet or to the weapon) and they run the risk of catching on obstacles during movements performed by the soldier.
In addition, movements or falls of the soldier may lead to traction, twisting, or shear forces being exerted both on the cables and on the connectors that connect them to the apparatuses.
The connectors run the risk of being dirtied by mud or sand and they must be leaktight whether or not they are connected in order to ensure that moisture cannot establish electrical leaks and lead to the contact of the connectors being destroyed by electrolysis.
Measures for protecting cables and connectors, such as incorporating them in a garment and providing leaktight caps, increase the weight of the garment as well as its cost.
The connections also constitute unreliable zones of weakness that might endanger a mission.
Nevertheless, such radio connections present drawbacks:they can be detected, intercepted, and / or jammed; andthey rely on antennas that present directivity, particularly since they are close to the body, and also polarization sensitivity that may prevent data being transmitted when the soldier is in certain positions.
Infrared wireless connections have also been proposed, however they do not provide significant improvements in the above-mentioned drawbacks.

first embodiment

[0030]With reference to FIGS. 1 to 3, the set of apparatuses in accordance with the invention is integrated in a garment, given overall reference 1, in the form of a jacket to be worn by a soldier and including a plurality of pockets, some of which receive respective apparatuses. The apparatuses in this embodiment comprise a computer 3, a radio transceiver 4, and a telescopic sight 5 optionally secured to a weapon 6.

[0031]Each apparatus 3, 4 comprises a box 7 of electrically insulating material containing a processor unit 12 arranged to send and receive electrical signals carrying data and capable of extracting data from a received electrical signal. The box 7 has an outer bottom face covered by a plate 13 made of an electrically conductive material, and an outer top face covered in a layer of metal plating forming an electrically conductive plate 14. The plates 13 and 14 may be inside the box and / or they may be identical in structure. The plates need to be spaced apart from conduct...

second embodiment

[0061]The electrical signals may be of optionally modulated alternating type, or they may be alternating signals with a DC component, or they may be DC signals (in the second embodiment).

[0062]If the quality of the received signal is too poor, given firstly that its level needs to be limited on transmission to avoid any physiological discomfort (or indeed danger), and also given that it is subjected to attenuation and deformation in the body, it is possible to have recourse to various types of analog modulation, and in particular frequency modulation, single side band modulation, phase modulation, quadrature modulation, etc., and also to various kinds of digital modulation, the list thereof not being limiting either. Any known signal extraction technique may advantageously be used.

[0063]In the first embodiment, and if necessary, in order to reduce attenuation of the signal it is possible to increase the frequency at which it is conveyed, to use plates of greater area, or to reduce t...

Abstract

A set of a first apparatus and a second apparatus that are secured to a garment, each of which includes an electrical signal processor unit connected to a first terminal and to a second terminal. At least the second terminal faces an inside surface of the garment, the processor units and the terminals being arranged to perform data transmission between the two apparatuses by establishing at least one wireless connection between the first terminals of the two apparatuses.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method of conveying data between two electronic apparatuses carried or worn by at least one user.[0002]The invention also relates to a set of at least two apparatuses for implementing the method.BACKGROUND OF THE INVENTION[0003]Progress in electronics and computing, miniaturization of components, and increased battery lifetime are making it possible for certain professionals, such as soldiers, to be fitted with electronic apparatuses or devices that provide them with assistance in accomplishing their missions. Such electronic apparatuses include, in non-limiting manner, a display device housed in a helmet and enabling close-up viewing and / or viewing in poor light, a communications unit having a transceiver associated with a microphone and an earphone, a computer for recording and / or consulting information, a telescopic sight mounted on a weapon, . . . . These various apparatuses are connected to one another, e.g. so that...
