I1 was defined in the main patent an analog force detection device in the form of a sensor or probe comprising an elastically deformable body and equipped with an optical transceiver assembly whose transmitted light flux is variable depending on the diformation of said body.
Le corps de la sonde est un tube rectiligne étanche à la lumière en étant agencé et/ou conformé directement ou d'une manière rapportée pour revenir à son état initial après annulation de la force de déformation. L'émetteur est convenablement monté à l'intérieur de l'une des extrémités du tube, tandis que le récepteur est monté à l'intérieur dudit tube à l'autre extrémité opposée, ledit récepteur étant relié à un appareil de traitement du signal optique compte-tenu des applications recherchées.The body of the probe is a rectilinear tube tight to the light by being arranged and / or shaped directly or in a reported manner to return to its initial state after cancellation of the deformation force. The transmitter is suitably mounted inside one end of the tube, while the receiver is mounted inside said tube at the other opposite end, said receiver being connected to an optical signal processor. taking into account the applications sought.
Selon l'addition, à partir de cette conception de base, on a voulu préciser les moyens spXcifiques combinés de mise en oeuvre de l'appareil de traitement du signal optique. According to the addition, on the basis of this basic design, it was desired to specify the specific combined means for implementing the optical signal processing apparatus.
Dans ce but, selon une première forme de réalisation préférée mais non rigoureusement limitative, la sonde est reliée à un module d'amplification asservi d'une part à un système de réglage de la sensibilité et, d'autre part, à un système d'étalonnage de la sonde, la sortie de I'amplificateur étant connectée à un module de traitement du signal émis relié à un système de controle visuel et/ou sonore.La sortie de l'amplificateur est reliée à deux comparateurs de tension dont l'un est assuiet- ti à un potentiomètre de consigne haute et l'autre à un poten tiomêtre de consigne basse, les sorties desdits comparateurs étant connectées à un module de signalisation sonore et/ou à un module de signalisation visuelle dont les entrées sont reliées, par l'intermédiaire d'un module de sélection, à un compteur de mouvement. To this end, according to a first preferred but not strictly limiting embodiment, the probe is connected to an amplification module controlled on the one hand by a system for adjusting the sensitivity and, on the other hand, with a system of calibration of the probe, the amplifier output being connected to a signal processing module connected to a visual and / or sound control system. The amplifier output is connected to two voltage comparators, one of which one is based on a high setpoint potentiometer and the other on a low setpoint potentiometer, the outputs of said comparators being connected to an audible signaling module and / or to a visual signaling module whose inputs are connected, through a selection module, to a motion counter.

Comme indiqué dans le brevet principal, l'émetteur de la sonde est relié à une alimentation électrique quelconque que présente l'appareil, tandis que le récepteur est relié à un circuit de détection et de traitement du signal optique.In the accompanying drawings
- Figure 1 is a block diagram of the folded up appa
- Figure 2 is a perspective view of the apparatus;
As indicated in the main patent, the transmitter of the probe is connected to any power supply that the device has, while the receiver is connected to a circuit for detecting and processing the optical signal.
A cet effet, la sonde désignée dans son ensemble par (S) et notamment le récepteur, est reliée à un module d'amplification (6) asservi, d'une part, à un système de réglage de sensibilité (7) et, d'autre part, à un système d'étalonnage (8). To this end, the probe designated as a whole by (S) and in particular the receiver, is connected to an amplification module (6) controlled, on the one hand, by a sensitivity adjustment system (7) and, d on the other hand, to a calibration system (8).
Les systèmes de réglage de la sensibilité et d'étalonnage s'opèrent au moyen de potentiomètres respectivement (7ar et (Sa). Dans l'exemple illustré,. le réglage de la sensibilité s'effectue selon 3 niveaux différents. L'étalonnage s'effectue en plus ou en moins par rapport à une position neutre en fonction du type de la sonde, de la fonction recherchée. The sensitivity adjustment and calibration systems are operated by potentiometers respectively (7ar and (Sa). In the example illustrated, the sensitivity adjustment is carried out at 3 different levels. 'performs more or less than a neutral position depending on the type of probe, the desired function.
La sortie de l'amplificateur (6) est connectée à un module de traitement du signal (9), ledit module étant relié à un système de contrôle visuel et/ou sonore (lu). Ces différents modules et circuits électroniques (6 > , (7), (8), (9) et (10), constituent la base de l'appareil. The output of the amplifier (6) is connected to a signal processing module (9), said module being connected to a visual and / or sound (read) control system. These different electronic modules and circuits (6>, (7), (8), (9) and (10) constitute the base of the device.
La sortie de l'amplificateur (6) est reliée à deux comparateurs de tension (il) et (12) dont l'un est assujetti à un potentiomètre de consigne haute (13), tandis que l'autre est assujetti à un potentiomètre de consigne basse (14). Ces poten tiomètres ont pour but de fixer un seuil supérieur ou inférieur des valeurs à atteindre par l'utilisateur. The output of the amplifier (6) is connected to two voltage comparators (il) and (12), one of which is subject to a high setpoint potentiometer (13), while the other is subject to a potentiometer of low setpoint (14). The purpose of these potentiometers is to set an upper or lower threshold of the values to be reached by the user.
La sortie de chaque comparateur (11) et (12) est connectée à un moyen de contrôle visuel et/ou sonore (15-16) et (1718). De mimez la sortie de chaque comparateur est reliée à un compteur (19) qui a pour but d'indiquer à l'utilisateur si la consigne fixée est atteinte. The output of each comparator (11) and (12) is connected to a visual and / or sound control means (15-16) and (1718). Miming the output of each comparator is connected to a counter (19) which aims to indicate to the user if the set point is reached.
En amont du compteur (19), est interposé un module de sélection (20) de comptage des mouvements des consignes basse et haute ou basse ou haute. Ce module de sélection (20) est connecté à la sortie de chacun des comparateurs (11) et (12). Upstream of the counter (19), there is interposed a selection module (20) for counting the movements of the low and high or low or high setpoints. This selection module (20) is connected to the output of each of the comparators (11) and (12).
I1 est bien évident que le nombre de comparateur n'est pas limitatif et peut entre supérieur à deux. Inversement, dans une version simplifiée, l'appareil peut être équpée d'un seul comparateur. It is quite obvious that the number of comparators is not limiting and may be greater than two. Conversely, in a simplified version, the device can be equipped with a single comparator.
D'une manière indépendante à l'asservissement cidessus, l'appareil reçoit un moyen de chronométrage (21) avec signal visuel (21a). Independently of the above control, the device receives a timing means (21) with visual signal (21a).
Eventuellement, le synoptique décrit et illustré pourraît autre appliqué à un autre type de capteur que celui d6- fini dans le brevet principal auquel se réfère la présente addition. Optionally, the block diagram described and illustrated could be applied to another type of sensor other than that defined in the main patent to which the present addition refers.
