Abstract

Personal device for short-range wireless communication for police motorcyclist including a dual frequency-modulation receiver 1 installed on the rider, an inverter 2 allowing simultaneous listening to radio calls and to the microphone or just the sounds from the microphone, a microphone 3 operates a voice-controlled box 4 driving a relay 5 serving to switch the antenna 6 over to the dual frequency-modulation transmitter 7, headphones 9 making it possible to listen to the amplified sounds directly in the helmet. On the motorcycle a dual frequency-modulation receiver 10 simultaneously feeds the handset input of the radio of the motorcycle and a voice-controlled box 11 operating a relay 12 which replaces the transmit/receive pedal of the original handset, a voice-controlled box 13 operated by the sound output from the radio of the motorcycle switches on a transmitter 14 which is doubly frequency-modulated by the low frequency intended for the original loudspeaker and switches the antenna 15 by means of a relay 16. A variant includes a bone-conduction transducer 17 as replacement for the headphones 9.

Description

La présente invention concerne les casques des motards de
Gendarmerie et de Police. Ces casques présentent l'avantage d'ê- tre très ajustés à la personne qui le porte, ce qui assure une excellente protection en cas de chute, mais présente de ce fait l'inconvénient d'être aussi étanches aux sons, notamment à ceux qui proviennent du haut-parleur de la radio de bord ou d'un interlocuteur tel qu'un usager de la route arrêté pour un contrôle.
The present invention relates to biker helmets of
Gendarmerie and Police. These helmets have the advantage of being very close to the wearer, which provides excellent protection in the event of a fall, but therefore has the drawback of being also soundproof, especially to those which come from the on-board radio speaker or from an interlocutor such as a road user stopped for a check.

Une solution consisterait à installer des écouteurs dans le casque, ces écouteurs seraient reliés en parallèle sur le haut-parleur, qui n'assure pas la discrétion ; cependant, Si cela permet d'entendre la radio avec une meilleure discrétion et plus de confort, on ne résoud pas le problème de la conversation avec un interlocuteur, de plus le motard est relié à la moto avec le risque que cela comporte en cas de chute. One solution would be to install headphones in the headset, these headphones would be connected in parallel on the speaker, which does not provide discretion; However, if this allows you to hear the radio with better discretion and more comfort, we do not solve the problem of the conversation with an interlocutor, moreover the biker is connected to the motorbike with the risk that that involves in the event of fall.

Une amélioration notable consiste à doter le motard d'un récepteur autonome accordé sur la bande Gendarmerie et d'écouteurs incorporés au casque et reliés à la sortie récepteur, cela présente l'avantage de permettre la réception par tous les motards de la compagnie ; l'inconvénient est que le motard doit disposer au minimum de quatre fréquences de travail sur son récepteur. A notable improvement consists in equipping the motorcyclist with an autonomous receiver tuned on the Gendarmerie band and with earphones incorporated in the helmet and connected to the receiver output, this has the advantage of allowing reception by all the motorcyclists of the company; the disadvantage is that the rider must have at least four working frequencies on his receiver.

Une commutation permettrait de percevoir directement dans le casque les sons extérieurs captés par un microphone et amplifiés, le motard sera cependant toujours obligé de se rendre à sa moto pour répondre à la radio lorsqu'il est concerné par l'appeL
Un perfectionnement au système peut entre apporté en utilisant un récepteur et un émetteur commandé par un détecteur de signal, directement installés sur le motard lui-même, les deux étant accordés sur une fréquence commune.
A switching would allow to directly perceive in the helmet the external sounds picked up by a microphone and amplified, the biker will however always be obliged to go to his motorbike to answer the radio when he is concerned by the call.
An improvement to the system can be made by using a receiver and a transmitter controlled by a signal detector, directly installed on the rider himself, the two being tuned to a common frequency.

Sur la moto, un émetteur renvoie par la voie des ondes les signaux provenant de l'amplificateur de la radio et destinés au haut-parleur, un récepteur capte la réponse du motard, un détecteur de signal commandant un relais commute la radio de la moto de la réception à l'émission ; l'émetteur et le récepteur sont accordés sur la fréquence de ceux installés sur le motard et travaillent en double modulation de fréquence. On the motorbike, a transmitter sends back by waves the signals coming from the amplifier of the radio and intended for the loudspeaker, a receiver collects the response of the biker, a signal detector controlling a relay switches the radio of the motorbike from reception to transmission; the transmitter and receiver are tuned to the frequency of those installed on the biker and work in double frequency modulation.

L'émetteur et le récepteur installés sur le motard traraillent de la même manière, ce mode de modulation permet le secret dans les liaisons homme-moto même vis à vis de l'homme de la rue possédant un récepteur à balayage de fréquence puisque à la réception on doit disposer d'un double démodulateur. The transmitter and the receiver installed on the biker work in the same way, this mode of modulation allows secrecy in the man-motorcycle connections even with respect to the man in the street having a frequency sweep receiver since at the reception you must have a double receiver.

Dans la patrouille généralement une seule moto est équipée de radio, cependant, si les deux motards sont équipés du dispositif, n'importe lequel des deux peut recevoir et répondre à la radio sans outre obligé de se rendre à la moto. In the patrol generally only one motorcycle is equipped with radio, however, if the two bikers are equipped with the device, either of them can receive and answer the radio without being obliged to go to the motorcycle.

De plus, si l'émetteur de la moto est assez puissant pour couvrir quelques kilomètres, il est intéressant de noter que lors d'une escorte (course ou autorité, par exemple) toute l'escorte recevra les ordres du chef de convoi simultanément et, Si l'ensemble est assez groupé, chaque élément pourra accuser réception de l'appel par l'intermédiaire de la seule moto équipée de radio de bord. In addition, if the motorcycle transmitter is powerful enough to cover a few kilometers, it is interesting to note that during an escort (race or authority, for example) the entire escort will receive orders from the convoy leader simultaneously and , If the assembly is sufficiently grouped, each element will be able to acknowledge receipt of the call via the only motorbike equipped with on-board radio.

Le dispositif pourrait aussi être utilisé par des patrouilles en voiture ou par un gendarme effectuant une enquête à domicile ou assurant le maintien de l'ordre.  The device could also be used by car patrols or by a gendarme carrying out a home investigation or ensuring the maintenance of order.

Pour assurer la discrétion des communications d'une manière plus efficace on utilisera, là aussi, la double modulation qui consiste à moduler en fréquence la porteuse HF par une fréquence ultrasonore, elle-même modulée en fréquence par les fréquences audio. To ensure the discretion of communications in a more efficient manner, we will again use the double modulation which consists in frequency modulating the HF carrier by an ultrasonic frequency, itself frequency modulated by the audio frequencies.

La figure 1 explicite la configuration du système sous forme de synaptique. Celui-ci est constitué par un récepteur (1) à double modulation de fréquence mis en service par l'inverseur (2) servant à écouter le microphone (3) ou bien la radio de bord plus le microphone ; lorsque l'inverseur est dans cette dernière position un détecteur de signal (4), piloté par le microphone, commute l'antenne (6) au moyen d'un relais (5) sur l'émetteur (7) à double modulation de fréquence dès que l'on parle à proximité du microphone ;; le récepteur est constamment en service, mais ne génère pas de souffle en l'absence de porteuse à la réception t un jack (8) à coupure m hors service le microphone incorporé lorsqu'on branche un microphone extérieur, des écouteurs (9) permettent d'entendre le son reçu et amplifié directement dans le casque. Figure 1 explains the system configuration in the form of a synaptic. This consists of a receiver (1) with double frequency modulation put into service by the inverter (2) used to listen to the microphone (3) or else the on-board radio plus the microphone; when the inverter is in the latter position a signal detector (4), controlled by the microphone, switches the antenna (6) by means of a relay (5) on the transmitter (7) with double frequency modulation as soon as we speak near the microphone; the receiver is constantly in use, but does not generate breath in the absence of a carrier on reception t a jack (8) with cut-off m out of service the built-in microphone when an external microphone is connected, headphones (9) allow hear the received and amplified sound directly in the headphones.

Sur la moto un récepteur du même type (10) à double modulation de fréquence pilote un détecteur de signal (11) qui commande un relais (12) qui remplace la pédale émission-réception de la radio, la sortie du même récepteur attaque 11 entrée micro phone du combiné d'origine. On the motorbike a receiver of the same type (10) with double frequency modulation controls a signal detector (11) which controls a relay (12) which replaces the transmission / reception pedal of the radio, the output of the same receiver attacks 11 input micro phone of the original handset.

La sortie haut-parleur de la radio de la moto attaque'un deuxième détecteur de signal (13) qui commute l'antenne (15) au moyen d'un relais (16) sur l'émetteur de liaison (14) à double modulation de fréquence uniquement en présence d'un appel reçu par la radio de la moto ; dès la fin de la modulation l'antenne est commutée sur le récepteur (8) pour la réponse. The loudspeaker output of the motorcycle radio attacks a second signal detector (13) which switches the antenna (15) by means of a relay (16) on the link transmitter (14) with double modulation frequency only in the presence of a call received by the motorcycle radio; at the end of the modulation the antenna is switched to the receiver (8) for the response.

En lieu et place des écouteurs (9) on pourra utiliser un transducteur à conduction osseuse.  Instead of headphones (9), a bone conduction transducer may be used.
