SYSTEM FOR DETECTING MICROBAL MOVEMENT

Description

Scope of the invention

[0001] The field of the invention is that of the design and manufacture of electronic systems and more specifically of motorized opening systems.

[0002] The field of invention also includes the design and manufacture of containers such as luggage. State of the art

[0003] The opening and closing of a leaf relative to a frame on which the leaf is mounted can be done in a purely manual way as is traditional in the field of luggage, or can be done in a motorized way as can be seen in other technical fields.

[0004] For a design where the actuation is purely manual, the opening is classically coupled to the fixed frame using a hinge.

[0005] In this case, the opening is opened or closed simply by being pivoted around a pivot axis formed by the hinge.

[0006] According to a classic design of a manually operated luggage opening mechanism, the mechanism exerts little or no resistance against manipulation of the opening by a user.

[0007] Thus, a user can easily fold the opening onto the frame, thereby moving the opening from an open position to a position folded onto the frame.

[0008] Mechanisms with manual operation are generally equipped with means of locking the opening in its folded position on the frame.

[0009] Such locking mechanisms may consist of: a notch presented by the opening on one of its edges; a notch presented by the frame and intended to engage in the notch in the folded-down position of the opening; an actuator coupled to the notch to allow it to be retracted from the notch when the opening is opened.

[0010] The notch may have a bevel and return mechanisms in a projecting position. In this way, when the door is closed, it exerts pressure on the notch and pushes it back, thus allowing the door to move into its closed position. Once in this closed position, the notch is aligned with the notch, which, under the effect of the return mechanisms, engages in the notch and locks the door in its closed position.

[0011] Regarding motorized mechanisms, the use of electric motors allows a sash to be opened and closed relative to a frame without requiring human intervention. In this case, it is not necessary to manually open or close the sash, as the motor is capable of opening or closing it on its own.

[0012] These different types of mechanisms each have their own specific characteristics and inherent advantages. The purely manual and mechanical mechanism allows the opening to be closed in a natural and intuitive way for the user. The motorized mechanism, on the other hand, offers automatic closing of the opening, requiring no direct user intervention.

[0013] It may therefore be sought to reconcile the advantages of a classic opening mechanism with manual operation with those of a motorized mechanism.

[0014] In patent document published under number FR3107294, a closing system was proposed that uses sensors to determine whether a force is applied to the opening to trigger its closure. More generally, this system can be applied to detect the micro-displacement of a component relative to a body. US2017 / 082461 A1 discloses another known system.

[0015] With this system, a user can trigger an automatic lid closure by manually initiating it. The user doesn't need to fully guide the lid's closing action, as an electric motor takes over from the manually initiated movement. The automatic closing is therefore initiated in a particularly intuitive manner.

[0016] To improve the detection of the application of a force on the opening, and in particular to prevent a force applied to the distal end of the hinge opening from not being detected, or from being misjudged, the patent document proposes to use Hall effect sensors associated with magnets.

[0017] In practice, this improved detection is unsatisfactory due to an excessive number of unintentional triggers of the opening mechanism. Reducing the sensitivity of the Hall effect sensors leads to a decrease in unintentional triggers, but at the expense of the system's responsiveness. Objectives of the invention

[0018] The invention aims to overcome these drawbacks of the prior art.

[0019] More specifically, the invention aims to provide an electronic system that triggers a predetermined action as soon as a force is applied to a moving part relative to a body, and avoids unintentional triggering.

[0020] The invention also aims to provide such a system which exhibits undegraded responsiveness, particularly compared to that of the opening system according to the prior art with reduced sensitivity of the Hall effect sensors. Description of the invention

[0021] These objectives, as well as others that will emerge subsequently, are achieved through the invention, which relates to an electronic system comprising: a body; a movable organ relative to the body between a closed position in which it is folded towards the body, and at least one open position in which it is away from the body relative to the closed position; at least one pair of elements for detecting a micro-displacement of the organ when a user applies a force causing the organ to move from one of its positions towards another of its positions, the pair of elements comprising a Hall effect sensor carried by one of the organ and the body, and a magnet carried by the other of the organ and the body opposite the Hall effect sensor; an electronic unit parameterized to control a predetermined action if the micro-displacement causes the magnetic field detected by the Hall effect sensor to reach or exceed a first limit relative to a reference value of the magnetic field, characterized in that the electronic unit is parameterized with a calibration cycle configured to calibrate the first terminal comprising: a step of determining the reference value of the magnetic field using the Hall effect sensor in a stabilized position of the opening relative to the frame; a step of setting the first terminal according to the reference magnetic field.

[0022] Thanks to the system according to the invention, the triggering of the predetermined action occurs only following the application of sufficient force on the organ.

[0023] Indeed, the system according to the invention makes it possible to prevent "false positive" type measurements at the level of the Hall effect sensor from causing the predetermined action to occur untimely.

[0024] More specifically, it was noted that such "false positive" type measurements corresponded to measurements exceeding a programmed threshold for triggering the predetermined action, in the absence of the application of any effort on the organ.

[0025] The cause of such measurements has been identified as resulting from the environmental conditions in which the Hall effect sensor(s) are located.

[0026] For example, opening a window in a room can produce variations (temperature, pressure, humidity, ...) that may alter the accuracy of the Hall effect sensor(s), and cause "false positive" type measurements.

[0027] Consequently, performing a calibration cycle allows these environmental conditions to be taken into account in order to define an initial limit adapted to how the Hall effect sensor reacts under these conditions. Tests have shown a drastic reduction in "false positive" measurements, or even an absence of such measurements.

[0028] Moreover, such a first adapted limit avoids the use of a programmed and predetermined limit at a value so far removed that it would degrade the responsiveness of the system.

[0029] Preferably, the step of determining the reference value of the magnetic field includes: a substep of performing a plurality of measurements of the magnetic field captured by the Hall effect sensor; a substep of calculating an average of the plurality of measurements to calculate the reference value of the magnetic field.

[0030] The reference value for the magnetic field then takes longer to determine, but it is more precise. Furthermore, it also prevents the use of a value that is not representative of the actual average to set the first limit.

[0031] According to a preferred solution, the first bound parameterization step includes a substep of applying a first weighting factor to the reference value of the reference magnetic field to calculate the first bound.

[0032] In this way, the configuration is done simply, and the first weighting factor can be selected as accurately as possible to improve the responsiveness of the system.

[0033] According to a preferred variant, the electronic unit is parameterized to control another predetermined action if the micro-displacement generates a value of the magnetic field captured by the Hall effect sensor reaching or exceeding a second terminal opposite the first terminal relative to the reference value of the magnetic field.

[0034] The system also allows another predetermined action to be controlled if the force applied to the opening is in the opposite direction to the force capable of triggering the first predetermined action.

[0035] In other words, moving the organ towards the body can lead to a first predetermined action, while moving the organ away from the body can lead to a second predetermined action.

[0036] Advantageously, the calibration cycle is also configured to calibrate the second terminal by further including a parameterization step of the second terminal according to the reference value of the magnetic field.

[0037] According to a preferred solution, the parameterization step of the second limit includes a substep of applying a second weighting factor to the reference value of the magnetic field to calculate the second limit.

[0038] The setup is simple, and the second weighting factor can be selected precisely to improve the system's responsiveness.

[0039] According to a preferred characteristic, the electronic unit is parameterized to trigger the calibration cycle after the determination of a stabilization of the position of the organ by means of a position sensor, said position sensor being preferably formed by the Hall effect sensor.

[0040] In this way, a calibration is carried out as soon as the organ has reached a stabilized position, and this calibration makes it possible to take into account the environmental conditions of the Hall effect sensor(s) following a movement of the organ.

[0041] According to another preferred feature, the system includes an ambient temperature sensor, the electronic unit being set to trigger the calibration cycle after determining a variation in a temperature captured by the temperature sensor.

[0042] Since ambient temperature is a parameter whose variation has markedly produced variations in the ability of a Hall effect sensor to accurately measure a magnetic field, performing a calibration as soon as a temperature variation is detected avoids the measurement of "false positives" induced by this parameter.

[0043] According to a preferred embodiment: the body is a fixed part; the organ is a movable opening relative to the fixed part between the closed position in which it is folded back on the fixed part, and at least one open position; at least one actuator motorizing the opening and closing of the opening; the electronic unit is parameterized to control the actuator so that it causes the opening to close if the micro-displacement generates a value of the magnetic field captured by the Hall effect sensor equal to or greater than the first terminal.

[0044] The system is then a motorized opening system and it is thus possible to trigger the closing of the opening in a particularly reactive manner, while avoiding a closure caused by a "false positive" type measurement.

[0045] The invention also relates to a container comprising a box and a lid, characterized in that it implements the opening system described above, the box forming the fixed part, and the lid forming the opening part.

[0046] Such a container features a particularly high-quality and attractive opening system due to its responsiveness in triggering the movement of the lid.

[0047] The invention also relates to a method for calibrating a first triggering terminal of a predetermined action of an electronic system described above, characterized in that it comprises: a step of detecting the stabilization of the organ's position relative to the body; a step of determining a reference value of the magnetic field using the Hall effect sensor; a first step of setting the first terminal according to the reference value of the magnetic field.

[0048] Other features and advantages of the invention will become more apparent upon reading the following description of various preferred embodiments of the invention, given by way of illustrative and non-limiting examples, and the accompanying drawings, among which: [ Fig. 1 ] is a schematic side view representation of a container according to a first embodiment of the invention, comprising a box and a lid, for which a lid closing mechanism is shown; Fig. 2 ] is a schematic side view representation of a container opening mechanism according to the first embodiment of the invention; [ Fig. 3 ] is a perspective view of part of an open container according to a second embodiment of the invention; [ Fig. 4] is a schematic representation in a side cross-sectional view of part of a container, according to the second embodiment, with its lid in a closed position; [ Fig. 5 ] a schematic representation in cross-sectional side view of part of a container, according to the second embodiment, with its lid in an intermediate open position; ] Fig. 6 ] a schematic representation in cross-sectional side view of part of a container, according to the second embodiment, with its lid in a fully open position; ] Fig. 7 ] there figure 7 is a flowchart illustrating a calibration process according to the invention. Detailed description of the invention

[0049] A container according to the invention is illustrated by the figures 1 to 6 .

[0050] The container comprises a box 20 and a lid 10 movablely mounted on the box 20.

[0051] This container implements an electronic system according to the invention, and more specifically an opening system.

[0052] As will subsequently become apparent, the system implements a calibration process according to the invention.

[0053] The opening system includes a fixed frame 2, and an opening 1 mounted movable relative to the fixed frame 2.

[0054] The box 20 forms the fixed part 2, and the cover 10 forms the opening part 1.

[0055] In other words, the opening 1 is mounted to move relative to the fixed 2.

[0056] With reference to figures 1 to 6 the opening 1 is movable between a closed position and at least one open position.

[0057] In its closed position, the opening 1 is folded down onto the fixed part 2.

[0058] More generally, the electronic system comprises a body and a movable part relative to the body. In the present embodiments, the body is the fixed part, while the part is the opening part. However, it is conceivable that the body is a support and that the part is a button movable relative to the support.

[0059] The organ is thus mobile relative to the body between a so-called "closed position" in which it is folded towards the body, and at least one so-called "open position" in which it is away from the body relative to the closed position.

[0060] According to the figure 3 and as detailed below, the frame 2 has a frame 200. This frame 200 delimits a location which is occupied by the opening 1 in its closed position F.

[0061] With reference to the first embodiment illustrated by the Figures 1 And 2, the opening 1 is mounted to rotate only on the fixed part 2.

[0062] With reference to the second embodiment illustrated by the figures 3 to 6 , the opening 1 presents a more complex opening or closing kinematic compared to the first embodiment.

[0063] More specifically, opening 1 is: mobile in rotation relative to the fixed part 2 between a maximum opening position and an intermediate opening position; mobile in translation relative to the fixed part 2 between the intermediate opening position and the closed position.

[0064] The intermediate opening position, illustrated by the figure 5 , corresponds in particular to a position in which the opening 1 is sufficiently moved away from its closed position, by means of a translation, so that it can be grasped by a user of the container.

[0065] Of course, the container according to the first embodiment can also have an opening 1 which, while only being mounted to rotate freely, has an intermediate opening position comparable to that of the second embodiment.

[0066] Between its intermediate opening position and its maximum opening position, the opening 1 presents a plurality of other opening positions in which it can be stabilized.

[0067] To allow the opening 1 to move on the fixed frame 2, the system includes a hinge 3 between the opening 1 and the fixed frame 2.

[0068] Hinge 3 is described in more detail later with reference to the two embodiments.

[0069] The system also includes at least one pair of detection elements 5 for a micro-displacement of the organ when a user applies a force causing a micro-displacement of the organ from one of its positions towards another of its positions; an electronic unit 6.

[0070] The system further comprises, according to the present embodiments, at least one actuator 40, which is in this case an electric motor, the electronic unit 6 being coupled to the actuator.

[0071] As detailed later, the pair of detection elements 5 makes it possible to determine that a user is applying an effort to the organ, or in other words to the opening 1.

[0072] According to the present embodiment, the pair of detection elements 5 of a micro-displacement of the opening 1 makes it possible to determine that a force is exerted on the opening 1 to cause its displacement from one of its intermediate open positions towards its maximum open position, or from one of its open positions towards its closed position.

[0073] The electric motor(s) 40 power the opening and closing of the opening 1. For this purpose, the electric motor(s) 40 cooperate with the hinge 3.

[0074] According to the present embodiments, the system includes in particular two actuators, which are electric motors.

[0075] These electric motors are brushed DC motors. Each electric motor is further equipped with a gearbox 41 and produces a rotational motion.

[0076] The hinge more precisely comprises two sub-assemblies, a left sub-assembly and a right sub-assembly, each cooperating with one of the two electric motors.

[0077] Of course, it is conceivable that the hinge 3 comprises two sub-assemblies of which only one cooperates with a single actuator 40.

[0078] The system also includes means for stopping the electric motor.

[0079] These means of stopping the electric motor are configured to interrupt a closing of the opening 1 by the electric motor following the detection of a resistance going against the closing of the opening.

[0080] The electric motor(s) can drive the opening 1 on the fixed part 2 using the design described below of coupling the electric motor(s) to the hinge 3.

[0081] With reference to the figure 2 , and to figures 4 to 6, hinge 3 includes a mechanism for converting a rotational movement into a translational movement.

[0082] This conversion mechanism includes an intermediate component 43 which is movable in translation under the effect of the electric motor 40.

[0083] With reference to the figure 2 : The electric motor 40 and the reducer 41 allow a screw 42 to be driven in rotation; the conversion mechanism corresponds to a ball screw, the intermediate element 43 being more particularly a nut 430.

[0084] Nut 430 is coupled to screw 42.

[0085] The intermediate component 43, and more particularly the nut 430, is movable along a translation axis T which is formed by the extension axis of the screw 42.

[0086] According to the first embodiment illustrated by the figure 2in which the opening 1 is only mounted movable in rotation on the fixed 2, the hinge 3 also includes a first transmission arm 7 which couples the intermediate member 43 to the opening 1. More particularly, the first transmission arm 7 couples the intermediate member 43 to the cover 10.

[0087] As illustrated by the figure 2 , the first transmission arm 7 is more precisely coupled by a first end to the opening 1 on a first pivot point 71 which is eccentric from a first axis of rotation R of the opening 1. The first transmission arm 7 is also coupled by a second end, opposite to the first end, to the intermediate member 43 on a second pivot point 72.

[0088] The device is configured so that a translation of the intermediate member 43 in a first direction causes the opening of the opening 1 to open, and a translation of the intermediate member 43 in a second direction causes the opening 1 to close.

[0089] According to the second embodiment illustrated by the figures 4 to 6 in which the opening 1 has translational mobility between its intermediate opening position and its closed position, the hinge 3 has the same characteristics as that of the first embodiment, and also includes at least one movable frame 8 mounted movable in translation on at least one guide element 80 in translation presented by the frame 2.

[0090] More specifically, the hinge 3 comprises two movable frames 8, i.e. one movable frame 8 for each sub-assembly.

[0091] The opening 1 is then mounted to rotate on the movable frame(s) 8.

[0092] Complementary cam tracks, including a first cam track C1 and a second cam track C2 presented by the fixed part 2 and / or by the movable frames 8, allow the translational movement of the intermediate part 43 along the translational axis T to be transformed either into a translational movement of the opening part 1, or into a rotational movement of the opening part 1.

[0093] More specifically, according to the embodiment illustrated by the figures 4 to 6 , the mobile frame 8 carries the first axis of rotation R and a second axis of rotation A;

[0094] Furthermore, the opening 1 includes a fixed part 11 extending inside the box 20 in the closed position of the opening 1. This fixed part is integral with a main plane of the opening 1.

[0095] The fixed part 11 cooperates with the mobile frame 8 to allow the opening 1 to be mobile in rotation around the first axis of rotation R.

[0096] According to this embodiment, the hinge 3 comprises: a first cam P1 movable in the first cam track C1, the first cam P1 also being the first pivot point 71 to which the first transmission arm 7 is coupled; a second cam P2 movable in the second cam track C2; a second transmission arm 73 coupled to the first cam P1 at one end and to the second cam P2 at a second end; a third transmission arm 74 coupled to the second cam P2 at one end and to the second axis of rotation A at a second end.

[0097] As illustrated by the figures 4 And 5 , the translation of the intermediate member 43 along a first section of the screw 42 causes a translation of the movable frame 8 between a low position and a high position, and thus a translation of the opening 1 between its closed position and its intermediate opening position.

[0098] This translation of the moving frame 8 is made possible by the first cam track C1 and the second cam track C2, each of which has a straight section. The translation of the intermediate member 43 along the first section of the screw 42 causes, by means of the first transmission arm 7, the second transmission arm 73, the third transmission arm 74, and the constraints exerted by the cam tracks, the displacement of the first cam P1 and the second cam P2 only along the straight sections of their respective cam tracks.

[0099] As illustrated by the Figures 5 And 6 , the translation of the intermediate organ 43 along a second section of the screw 42 causes a rotation of the opening 1 around the first axis of rotation R, then in the high position, which is located on the movable frame(s) 8, and thus a rotation of the opening 1 relative to the fixed frame 2.

[0100] This rotation of the opening 1 is made possible by the first cam track C1 and the second cam track C2, each of which has a curved portion extending from its straight section. The translation of the intermediate member 43 along the second section of the screw 42, in turn, via the first transmission arm 7, the second transmission arm 73, the third transmission arm 74, and the constraints exerted by the cam tracks, causes the first cam P1 and the second cam P2 to move only along the curved portions of their respective cam tracks. The first cam P1 and the second cam P2 are thus more specifically driven in rotation around the first axis of rotation R and the second axis of rotation A, respectively.

[0101] As explained previously, the pair or pairs of detection elements 5 make it possible to determine that a force is exerted on the organ, and thus on the opening 1, to trigger a predetermined action, in this case the motorized closing or opening of the opening 1.

[0102] Each pair of elements comprises: a Hall effect sensor 51 carried by one of the opening 1 and the fixed 2; a magnet 52 carried by the other of the fixed 2 and the opening 1.

[0103] Indeed, with reference to figures 3 And 5 A Hall effect sensor 51 is carried by the frame 2, and a magnet 52 is carried by the sash 1. In the intermediate opening position of the sash 1, as illustrated by the figure 5 , magnet 52 is positioned opposite the Hall effect sensor 51.

[0104] This Hall effect sensor 51 is positioned in the immediate vicinity of frame 200.

[0105] More specifically, the Hall effect sensor 51 is positioned in the immediate vicinity of a front edge 201 of the frame 200, opposite a rear edge 202 of the frame 200, the hinge 3 being positioned in the frame 2 on the side of the rear edge 202 of the frame 200.

[0106] Such a Hall effect sensor 51 makes it possible to measure a variation in magnetic field and, thus, to detect the position of the magnet 52 relative to the Hall effect sensor 51 in order to determine the position of the opening 1 relative to the front edge 201 of the frame 200.

[0107] The electronic unit 6 is then parameterized to correlate a variation in the signal from the Hall effect sensor 51 generated by the application of a force on the opening 1 in its intermediate opening position with the micro-displacement.

[0108] According to other conceivable embodiments, the system may include a plurality of magnets 52 for the or each Hall effect sensor 51.

[0109] In this case, the position and intensity of the magnetic fields of each magnet 52 can be designed so that the Hall effect sensor can measure different magnetic field intensities in different stabilized positions of the opening 1.

[0110] For example, the magnets 52 can be positioned linearly with alternating polarity parallel to a straight line along which the Hall effect sensor 51 is located when the opening or closing of the door.

[0111] For this purpose and in a complementary manner, the Hall effect sensor 51 and / or the magnets can be attached to an arm attached to the opening 1 and which deploys when the opening 1 is opened.

[0112] According to other possible embodiments, the system can include a plurality of pairs of Hall effect sensor 51 and magnet(s) 52, distributed at different positions on the opening 1 and the fixed 2.

[0113] It should be noted that positioning the pair of detection elements 5 opposite the hinge 3 improves the system's sensitivity. This positioning is located at the point in the system where the range of motion is greatest, and where the user is most likely to apply pressure.

[0114] The electronic unit is 6 parameterized to control a predetermined action if the micro-displacement generates a value of the magnetic field captured CMC by the Hall effect sensor 51 which reaches or exceeds a first limit B 1 relative to a reference value of the magnetic field CMR.

[0115] In addition, the electronic unit 6 is parameterized to control another predetermined action if the micro-displacement generates a value of the magnetic field captured CMC by the Hall effect sensor 51 which reaches or exceeds a second terminal B 2 opposite the first terminal B 1 with respect to the reference value of the magnetic field CMR.

[0116] According to one application example, the first predetermined action could be turning on a light, while the other predetermined action could be turning off that light.

[0117] More specifically, according to this embodiment, the electronic unit 6 is configured to control the actuator 40 so that it drives: the closing of the opening 1 if the micro-displacement generates a value of the magnetic field captured CMC by the Hall effect sensor 51 equal to or greater than the first terminal B 1; the complete opening of the opening 1 from an intermediate open position if the micro-displacement generates a value of the magnetic field captured CMC by the Hall effect sensor 51 equal to or less than the second terminal B 2.

[0118] According to the invention, the electronic unit 6 is parameterized with a calibration cycle configured to calibrate the first terminal B 1.

[0119] According to the present embodiment, the calibration cycle is also configured to perform a calibration of the second terminal B2.

[0120] Thus, the calibration cycle includes: a step of determining a reference value of the CMR magnetic field using the Hall effect sensor 51 in a stabilized position of the component relative to the body, and more specifically of the opening 1 relative to the frame 2; a step of parameterizing the first terminal B 1 according to the reference value of the CMR magnetic field; a step of parameterizing the second terminal B 2 according to the reference value of the CMR magnetic field.

[0121] To determine whether the opening 1 is in a stabilized position, the system includes a position sensor which can, for example, be advantageously formed by the Hall effect sensor 51.

[0122] As detailed below, in the case where the position sensor is formed by the Hall effect sensor, the determination of a stabilized position is correlated with the stabilization of measurements from the Hall effect sensor and a moving average of these measurements.

[0123] The calibration cycle therefore includes a preliminary step of detecting the stabilization of the organ in relation to the body.

[0124] According to the present embodiment, the position sensor is formed by a separate sensor 91 which determines the position of a hinge element, called a "test element".

[0125] In this case, the transmission organ 43 forms the witness organ.

[0126] More specifically, the separate sensor 91 allows the position of the intermediate component 43, and more precisely of the nut 430, to be determined along its axis of translation T. The position of the opening 1 relative to the fixed 2 is then correlated to the position of the intermediate component 43 along the axis of translation T.

[0127] The evolution of the position of the intermediate organ 43 along the translation axis T makes it possible in particular to determine the evolution of the position of the opening 1. A stabilization of the position of the intermediate organ 43 then corresponds to a stabilization of the position of the opening 1.

[0128] In a simplified version, the step of determining the reference value of the CMR magnetic field can consist of a single reading of the magnetic field by the Hall effect sensor 51.

[0129] With reference to the figure 7 The step of determining the reference value of the CMR magnetic field includes: a substep of carrying out a plurality of measurements (M 1 , M 2 , ... M n ) of the magnetic field captured by the Hall effect sensor 51; a substep of calculating an average of the plurality of measurements (M 1 , M 2 , ... M n ) to obtain the reference value of the CMR magnetic field.

[0130] The number of measurements can be selected from a range of 4 to 40, advantageously between 8 and 25, and typically between 10 and 14. The sampling frequency can also be adjusted. Adapting the number of measurements and the sampling frequency can be particularly useful for optimizing system responsiveness.

[0131] For example, ten measurements can be taken at 200 Hz (5ms interval between each measurement).

[0132] This plurality of measurements then allows for the determination of an average.

[0133] The electronic unit 6 can be programmed to monitor the standard deviation of measurements and, if a significant deviation is detected, to restart the substep of performing a plurality of measurements. Thus, the substep is restarted if the difference between the lowest and highest measured values ​​in the plurality of measurements (M1, M2, ..., Mn) exceeds a set limit (for example, between 2mT and 50mT, typically between 5mT and 25mT, advantageously at 10mT). Consequently, the average is considered valid when the deviation is below the limit.

[0134] The parameterization step of the first B1 terminal includes a substep of applying a first weighting factor F1 to the reference value of the CMR magnetic field to calculate the first B1 terminal.

[0135] The parameterization step of the second B2 terminal includes a substep of applying a second weighting factor F2 to the reference value of the CMR magnetic field to calculate the second B2 terminal.

[0136] Generally speaking, as it is represented on the figure 7 , these parameters are represented by the following equations: B 1 = F 1 (CMR), and B 2 = F 2 (CMR).

[0137] According to a first variant, the first weighting factor F1 and the second weighting factor F2 are multiplication factors.

[0138] This corresponds to the following equations: B 1 = CMR*F 1 , and B 2 = CMR*F 2 .

[0139] For example, the first weighting factor F1 may correspond to 1.1 and the second weighting factor F2 may correspond to 0.9.

[0140] Thus, a reference value of the CMR magnetic field at 4 mT gives a first terminal B 1 at 4.4 mT and a second terminal B 2 at 3.6 mT.

[0141] In a second embodiment, the weighting as defined by the invention is a coefficient subtracted from or added to the reference value of the CMR magnetic field so as to obtain, respectively, the first terminal B1 and the second terminal B2. The coefficient(s) allow for symmetrical or asymmetrical terminals with respect to the reference value of the CMR magnetic field. For example, the first and second terminals B1 and B2 are 128 mT away from the reference value of the CMR magnetic field.

[0142] This corresponds to the following equations: B 1 = CMR+F 1 , and B 2 = CMR-F 2 .

[0143] These configuration steps end with a sub-step of registering the terminals.

[0144] According to an alternative embodiment of the invention, the reference value of the CMR magnetic field is a moving average. This is calculated from a plurality of measurements (M1, M2, ..., Mn) stored in a first-in, first-out (FIFO) buffer. An additional measurement, Mn+1, is obtained and subtracted from the resulting moving average. The absolute value of this measurement defines a deviation. If this deviation is less than or equal to a threshold, the moving average is considered stable. Otherwise, if the deviation exceeds this threshold, the additional measurement Mn+1 is pushed into the buffer, from which measurement M1 is ejected, in order to calculate an updated moving average and repeat the comparison step.Thus, new additional measurements are taken, progressively renewing the plurality of measurements stored in the buffer, until the average is obtained which slides until it is stabilized.

[0145] The calculation of the moving average of the measurements of the Hall effect sensor described above can also be implemented to determine the arrival in a stabilized position of the organ relative to the body, as mentioned above.

[0146] According to a particular embodiment, the minimum value Mmin and maximum value Mmax are extracted from the plurality of measurements (M1, M2, ...Mn) acquired to determine the amplitude difference of the plurality of measurements (M1, M2, ...Mn). This amplitude difference is calculated by subtracting the previously extracted minimum value Mmin from the maximum value Mmax. If the amplitude difference thus determined is less than the fixed limit threshold, then the average of the plurality of measurements (M1, M2, ...Mn) is calculated, which establishes the reference value of the CMR magnetic field. If the amplitude difference exceeds the fixed limit threshold, the procedure is repeated by acquiring a new plurality of measurements (M1, M2, ...Mn) that overwrites the previous plurality of measurements, in order to calculate a new amplitude difference and continue the steps described above until the reference value of the CMR magnetic field is obtained.

[0147] The electronic unit 6 is configured to periodically trigger the calibration cycle. In this way, the first and second terminals recorded in the electronic unit 6 are updated regularly.

[0148] The separate sensor 91 is also used to trigger the calibration cycle.

[0149] Indeed, the electronic unit 6 is configured to monitor the position of the opening 1 relative to the fixed 2 and to detect a stabilization of the position of the opening 1. This detection is carried out by means of the separate sensor 91.

[0150] Following the detection of a stabilization of the position of the opening 1 in a predetermined position, the electronic unit 6 is configured to trigger the calibration cycle.

[0151] Similarly, a change in ambient temperature or humidity can trigger the calibration cycle.

[0152] The system includes an ambient temperature sensor 92, and the electronic unit 6 is configured to monitor the temperature via the sensor 92 and detect any temperature variation. In this case, the electronic unit 6 is configured to trigger the calibration cycle.

[0153] The calibration cycle described above corresponds to a calibration process of at least one triggering terminal of a predetermined action, and in this case of two terminals, one of which triggers a predetermined action which is the closing of the opening, and the other triggers another predetermined action which is the opening of the opening.

[0154] The process also includes the various stages of the calibration cycle previously detailed.

[0155] To summarize, and with reference to the figure 7 This process includes: a step of detecting the stabilization ES of the position of the organ relative to the body; a step of determining ED a reference value of the magnetic field CMR using the Hall effect sensor 51; a first parameterization step EB1 of the first terminal B 1 according to the reference value of the magnetic field CMR; a second parameterization step EB2 of the second terminal B 2 according to the reference value of the magnetic field CMR; a monitoring step EU of system parameters to trigger a new calibration cycle if necessary.

[0156] The ES stabilization detection step may involve: a substep of carrying out a plurality of measurements M1, M2, ...Mn of the magnetic field captured by the Hall effect sensor 51; a substep of calculating an average of the plurality of measurements M1, M2, ...Mn to determine, by maintaining a new measurement Mn+1 in the average, a stabilization of the position of the organ relative to the body.

[0157] The system and method according to the invention make it possible to trigger predetermined actions, namely in particular a closing, and an opening for the embodiment described above, in a particularly reactive manner as soon as the organ is manipulated, and without allowing undesired triggering of a predetermined action.
