[0063] Figures 1 to 4 illustrate a representation of a measuring station 100 according to at least one embodiment of this description. The measuring station 100 is primarily in the form of a base 102 on which a user can place their feet, for example, flat. The user can be on the measuring station or seated in a chair. In the normal operating position, the user's feet are placed flat on the measuring station 100. The thickness of the base 102 is, for example, less than 10 cm, or even 6 cm. The measuring station 100 includes one or more sensors 104 capable of measuring physiological information about a user.

[0064] In one embodiment, certain sensors 104 (for example, electrodes) are mounted on a substrate 106 of the base 102, the substrate being configured to receive the feet of a user. The substrate may be a rigid plate, as illustrated in the figures, and referred to as the measuring plate 106. The measuring plate 106 defines a plane parallel to an XY plane. The measuring plate 106 may be made of glass. However, the substrate may be deformable under the weight of the user. The substrate 106 may be mounted on a base 108, for example, a rigid base, or on feet (not shown). In the case of a base 102 functioning as a bathroom scale, sensors are positioned between the substrate 106 and the base 108 (a so-called "sandwich" architecture) or between the substrate 106 and the feet (a so-called "feet" architecture). The sensors can be load cells (usually four) which allow us to obtain a weight, and therefore a mass of a user.The base 108 can be made of metal (aluminum, steel, etc.) or plastic.

[0065] As seen in [Fig.2], the measuring station 100 further includes a support plate 202, which can be attached to the measuring plate 106. The support plate 202 is designed to receive part of the electronics of the measuring station 100, in particular via a printed circuit board (PCB) mounted on the support plate 202. The support plate 202 is therefore positioned between the base 108 and the measuring plate 106.

[0066] In a pedestal architecture, two groups are defined as moving relative to each other: the feet on the one hand (fixed group), and everything else on the other (mobile group). Load cells mechanically connect these two groups. The support plate, if present, is then generally hidden by an external cover attached to the measuring plate. Visually, only the mobile part is generally visible.

[0067] In a sandwich architecture, two groups are defined as moving relative to each other: the base 108 (and associated elements) on the one hand (fixed group), and all the The remaining part (mobile group) is mechanically connected by load cells. Visually, both groups are usually visible.

[0068] In one embodiment, the measuring station 100 further includes a handle 110, suitable for being grasped by at least one hand of the user, illustrated in Figures 3 and 4. The handle 110 can be connected to the measuring station by a cable 302 (visible in [Fig.3]). The cable 302 allows, in particular, the transmission of electrical signals between the handle 110 and the base 102. To create a practical measuring station 100 without a loose cable, the cable 302 can extend and retract (for example, wind and unwind) inside the base 102. For this purpose, a reel (visible in [Fig. 8]) is arranged in a space provided between the substrate 106 and the base 108. At least two positions are thus defined for the handle: a stowed position (visible in Figures 1 and 2) and an extended position (visible in [Fig. 3]). The base 102 also includes a handle support 112 which can accommodate the handle 110 in the stowed position.The handle support 112 is, for example, mounted on the substrate 106. The handle support 112 can be an added component on the measuring plate 112. For example, the handle support 112 can be glued to the measuring plate 106 (especially when it is made of glass) or screwed in place. It will be described in more detail later. The handle 110 also includes at least one sensor 402.

[0069] The handle 110 is used to perform at least one of the following measurements: ECG (1-channel ECG between both hands or multi-channel ECG with other limbs), BIA (so-called "segmental"), IPG. The sensors of the handle 110 are selected from, in particular: optical sensor for PPG and electrodes.

[0070] The base 102 may include a display 114 (for example, a screen or an LED or electronic ink display) for displaying information to the user. The screen 114 is shown in dotted lines in [Fig. 1] because, in the example in the figures, it is not or barely visible when it is switched off.

[0071] The base 108 of the base 102 may include a chamfer 204 to facilitate gripping the measuring station 100 when it is on the ground.

[0072] In one embodiment, the base 102 has an essentially rectangular shape in an XY plane. The base 102 has, for example, an essentially parallelepiped shape in XYZ space.

[0073] When the measuring station 100 is positioned flat, the measuring plate 106 is parallel to an XY plane. The measuring station 100 comprises a longitudinal dimension in an XY plane and a transverse dimension in an XY plane orthogonal to the longitudinal direction. Height means the dimension along the Z-axis (also called thickness); width means the transverse dimension along the X-axis; length means the longitudinal dimension along the Y-axis. In normal use, the user's feet are positioned along the Y-length of the base 102. The edge of measuring station 100 (or of base 102, or of measuring plate 106) that is closest to the anterior part of the foot in normal use (i.e. the toes) is called anterior edge 206 and the opposite edge of measuring station 100 (or of base 102, or of measuring plate 106), that is closest to the posterior part of the foot in normal use (i.e. the heel) is called posterior edge 208. A median axis can be defined, according to the length Y (longitudinal), around which the measuring plate 106 is symmetrical and which allows us to define a left part, intended for the left foot, and a right part, intended for the right foot. The width X102 of the base 102 can be between 330 and 400mm (for example about 357mm) and the length of the base Y102 can be between 300 and 360mm (for example about 325mm).The length and / or width of the measuring plate 106 may be slightly less than those of the base 108, so that the measuring plate 106 is slightly recessed relative to the base 108. In this case, the length and width of the base 108 correspond respectively to the length and width given above for the base 102. Such a design protects the measuring plate 106 from impacts and contact with the external environment. French application FR2106653 describes such a solution.

[0074] Specifically, as illustrated in [Fig. 2]: the height Z102 of the base 102 can be between 20 and 35 mm (for example, between 35 and 40 mm) and the maximum height Z100 of the measuring station 100 can be between 45 and 55 mm (for example, 51 mm). As shown in the figures, only the handle support 112 and the handle 110 protrude in the Z direction relative to the measuring plate 106. Detailing the various dimensions: the height H108 of the base 108 can be between 10 and 20 mm (for example, 18 mm), the height Z202 of the support plate 202 can be between 3 and 6 mm (for example, 4 mm), and the height Z106 of the measuring plate 106 can be between 4 and 8 mm (for example, 6 mm).

[0075] The cable 302 can have a length between 50cm and 120cm. The length is chosen so that most users can grasp the handle while standing with their hands downwards (at rest).

[0076] The measuring station 100 could, however, have different shapes and / or dimensions, provided that the shape and / or dimensions allow for obtaining the measurements described herein. In particular, the base 102 could have an oval or more rounded shape in the XY plane.

[0077] The measuring station 100 can have a mass between 3 and 6 kg (for example between 4 and 5 kg).

[0078] Thanks to the sensor(s) of the base 102 and / or the sensor(s) of the handle 110, the measuring station 100 can perform a group of measurements on the user. In particular, the sensors 104 used include electrodes formed from electrically conductive paths mounted on the substrate 106 and / or the handle 110 (metal inserts, metal deposits, etc.). Some measurements may require only sensors from the base 102, other measurements may require only sensors from the handle 110, and still other measurements may require both sensors from the handle 110 and the base 102.

[0079] The measuring station 100 can thus perform an ECG using the handle 110 (for example, a single-lead ECG), or an ECG using the handle 110 and the base 102 (for example, a multi-lead ECG, such as a six-lead ECG). The measuring station 100 can thus perform a body impedance analysis (BIA) using the handle 110 and / or the base (between-day BIA and / or segmental BIA). The measuring station can thus perform an IPG in the leg arch ("between legs") or IPG in the foot ("in the foot").

[0080] The sensors may include electrodes capable of measuring and / or applying a voltage (DC or AC) and / or a potential (DC or AC), and / or injecting and / or receiving a current (DC or AC). The functions of these electrodes may be selected from the following list: i+ and i-, for injecting AC current into a user's body; V+ and V-, for measuring a potential difference in a user's body; RA, LA, and LL, for measuring an electric current flowing through a user's body. Electrodes i+ and i-, V+ and V- are used for a BIA, an IPG, or an ICG; electrodes RA, LL, and LL are used for an ECG.

[0081] In particular, the measuring station 100 is configured to perform different measurements. As the number of electrodes is limited (for considerations of surface area and number), the measuring station 100 has a particular arrangement of electrodes, with a switch.

[0082] As previously stated, the sensors may include load cells, through which the measuring station 100 can measure a weight and perform a BCG.

[0083] The handle 110 is illustrated in detail in [Fig. 4]. The handle 110 enables the measuring station 100 to perform a wider variety of measurements or more comprehensive measurements, thanks to an electrical connection with at least one hand, or even both hands. In particular, segmental BIA and / or multi-channel ECG are made possible by adding the handle 110 to the base 102. The sensors 402 of the handle 110 include, for example, electrodes capable of measuring and / or applying a voltage and / or a potential and / or injecting and / or recovering a current.

[0084] In one embodiment, in the stowed position, the handle 110 is located near the front edge 206. This means that the handle support 112 is located near the front edge 206. For example, the handle support is located at most between 1 and 3 cm from the front edge 206.

[0085] In one embodiment, the handle 110 comprises four electrodes, arranged in two pairs: one pair for the left hand and one pair for the right hand. For this purpose, the electrodes of the handle are designated as: electrodes LH1, LH2, side by side on a left portion of the handle 110, and electrodes RH1, RH2, side by side on a right portion of the handle (by left and right portions, respectively, it is understood that the portion of the handle is intended to be in contact with the left and right hands, respectively). "Side by side" here means with a space between the electrodes, to isolate the electrodes from one another. The electrodes are therefore arranged end to end between two ends of the handle 110. When the handle 110 is straight, the electrodes are arranged end to end along the main direction of the handle 110.Electrodes LH1 and RH1 are positioned axially on one end of the handle; electrodes LH2 and RH2 are positioned axially on the center of the handle. Therefore, the electrodes are, in order: LH1, LH2, RH2, RH1.

[0086] In one embodiment, the sensors 402 of the handle 110, when they are electrodes, are made in the form of several metallic inserts in the handle 110. Materials that can be used for the metallic inserts include stainless steel, titanium, brass, ITO, or conductive plastics. For signal processing and / or acquisition, particularly of ECG signals, the handle 110 may include processing electronics (operational amplifier follower, etc.), especially for ECG. It is generally preferable to amplify the signal as close as possible to the electrodes because the cable can pick up ambient noise.

[0087] Figure 5 illustrates a schematic view of the overall architecture 500 into which the measuring station 100 can be inserted. This overall architecture forms a system comprising the measuring station 100. In particular, the measuring station 100 can communicate with third-party devices via a communication network 510, which is, for example, a wireless network (specifically, a network compatible with at least one of the following communication protocols: Bluetooth, Wi-Fi, cellular, etc.). The third-party devices may include a server 520 and a mobile terminal 530 (smartphone, etc.). The server 520 may include control circuitry 522, including a processor 524 and memory 526, and an input / output (FO) interface 528, which allows the control circuitry to receive and send data to the communication network 510.The mobile terminal 530 may include control circuitry 532, including a processor 234 and memory 236, and an input / output interface (1 / 0) 538, which allows the control circuitry to receive and send data. The server 520 is a remote server, for example, located in a data center. The mobile terminal 530 further includes a user interface 540 (UI) configured to display information to the user and, if necessary, allow them to enter information (such as height, gender, etc.). In particular, the control circuitry 532 is configured to run an application managing the environment of the measuring station 100. The mobile terminal 530 is a personal item belonging to the user, typically kept close to them.

[0088] The measuring station 100 can communicate with the server 520 and / or the mobile terminal 530. In one embodiment, the measuring station 100 can communicate directly with the mobile terminal 530, for example via Bluetooth or Bluetooth Low Emission (BLE). This communication can be implemented during the installation of the measuring device 100, in particular to pair it with the mobile terminal 530 and / or to configure a connection to the server 520 that does not go through the mobile terminal 530 and / or as a backup in case of a failed communication with the server 520. In another embodiment, the measuring station 100 can communicate directly with the server 520, without going through the mobile terminal 530. This communication allows the user to use the measuring station even without having their mobile terminal 530 nearby.

[0089] The measuring station 100 also includes a control circuitry 550 with a processor 552 and a memory 554, and an input / output (I / O) interface 556, which allows the control circuitry to receive and send data to the communication network 510. The processor 552 is configured to process data obtained from the sensors 104. In particular, the processor 552 can execute instructions from a program stored in the memory 554. The control circuitry 550 may include a microcontroller, which integrates the processor 552, the memory 554, and the input / output interface 556. The control circuitry 550 may further include an analog front end (AFE). The control circuitry 550 may also include an analog-to-digital converter (ADC).The measuring station 100 includes a voltage source 558 (e.g., DC) and a current source 560 (e.g., AC). The measuring station 100 also includes a voltmeter 562 (or any system capable of measuring voltage). The voltmeter 562 may be integrated into the AFE. The current source 560 may be integrated into the AFE, and the voltage source 558 may be integrated into the microcontroller MCU (e.g., via a digital-to-analog converter, DAC). Some sensors 104 (in particular the sensors 402 of handle 110 in [Fig. 4] or the electrodes 602 of handle 110 in [Fig. 6A]) are connected to the control circuitry 550 (e.g., to the MCU or the AFE). The measuring station 100 includes a... battery 564, capable of supplying energy to the various components of measuring station 100.

[0090] The control circuitry 550 and other electronic components can be mounted on a printed circuit board (PCB), which is, for example, attached to the support plate 202. Connectors link the electrical conductive paths from the measuring plate to the PCB. In order to change the electrode connections to the various components of the measuring station 100, the measuring station includes a switch 566. The switch 566, which may include a plurality of switches controlled by the MCU, will be described in more detail later.

[0091] The control circuitry 550 includes, for example, an ECG acquisition system, an impedance measurement system (for BIA or IPG), an ESC system (for the ESC). The ECG acquisition system includes electrodes (represented by 602 in Figures 6a and 6b and 402 in [Fig.4]) and an ECG electrical circuit 568 (which integrates, in particular, various amplification and / or filtering stages and a demodulator); The impedance measurement system includes electrodes (represented by 602 in Figures 6a and 6b and 402 in [Fig.4]), the current source 560, the voltmeter 562 and an impedance measurement electrical circuit 570 which connects the electrodes to the current source and the voltmeter (which incorporates various amplification and / or filtering stages): the ESC system includes electrodes, the voltage source 558 and an ESC electrical circuit 572 (which incorporates various electronic components, including resistors).The switch 566 allows the electrodes to be connected, in particular to the various circuits 568, 570, 572 mentioned above, or to be disconnected from all the electrodes of the control circuitry 550.

[0092] The control circuitry 550 is essentially located in the base 102, with the exception of some components (amplification, filtering and switches) arranged in a PCB in the handle 110, to process the signals before passing them through the cable 302.

[0093] As previously stated, the measuring station 100 also includes the display 114, such as a screen (OLED / PMOLD, Retina, etc.), to display information to the user. Alternatively, the measuring station 100 does not include a display.

[0094] The handle 110 is illustrated in detail in Figures 4, 6, and 7. The handle 110 enables the measuring station 100 to perform a wider variety of measurements or more comprehensive measurements, thanks to an electrical connection with at least one hand, for example, both hands. In particular, segmental BIA and / or multi-channel ECG are made possible by adding the handle 110 to the base 102. The sensors 402 of the handle 110 include, for example, electrodes 602 capable of measuring and / or applying a voltage and / or a potential and / or injecting and / or recovering a current.

[0095] As described previously, in one embodiment, the handle 110 comprises four electrodes, arranged in two pairs: one pair for the left hand and one pair for the right hand. For this purpose, the electrodes of the handle are designated as: electrodes LH1, LH2, side by side on a left portion of the handle 110, and electrodes RH1, RH2, side by side on a right portion of the handle (by left portion, respectively right portion, it is understood that the part of the handle is intended to be in contact with the left hand, respectively right hand; and by side by side includes a spacing between the electrodes). Electrodes LH1 and RH1 are positioned axially on the side of one end of the handle; electrodes LH2, RH2 are positioned axially on the side of the center. Thus, the electrodes are, in order: LH1, LH2, RH2, RH1. The 302 cable enters the handle between the LH1, LH2 electrodes on one side and the RH1, RH2 electrodes on the other.

[0096] As illustrated in [Fig. B], the electrodes 602 are positioned offset from the point where the cable 302 enters the handle 110. In the case of a cylindrical handle with axis A parallel to the transverse direction X of the measuring station 100 in its stowed position, where the insertion position of the cable 203 in the handle 110 defines 0°, the electrodes extend over an external surface of the handle 110 between -45° and +90° (in the counterclockwise direction with respect to the orthonormal coordinate system XYZ), or even between -30° and 80°. In the embodiment shown in the figures, the electrodes extend from -30° to +79° (angle covered by the electrodes of 109°, plus or minus 1°). The angles are defined in a cross-section of the handle 112 (a cutting plane orthogonal to the axis A, therefore a cutting plane in YZ when the handle 110 is positioned in the handle support 112).Positive angles between 0 and +180° are oriented towards the edge closest to the base 102. In other words, in the stowed position, the electrodes extend more on the handle towards the anterior edge 206 of the base 102 than towards the posterior edge 208.

[0097] More generally, for any shape of the handle (straight, slightly curved, non-cylindrical, etc.), the positioning of the electrodes can be defined as follows. The handle 110 includes a centerline 610, which is a line passing through the center of the volume defined by the handle 110, that is, a line defined by the centroids of successive cross-sections of the handle 110 (centroid of the curve defined by the external surface of the handle 110 in a cross-section). The handle 110 includes a lower line 612, which is a line defined, for successive sections of the handle 110, by the set of points on the external surface of the handle 110 that are closest to the measuring plate 106 (in the stowed position). For each cross-section at the midline, the angle passing through the midline and one end of the electrodes 602 on an external surface of the handle 110 is defined.The angle 0° is defined as that between the . The median and the lower line; positive angles are defined from 0° moving towards the front edge 206 and negative angles are defined from 0° moving towards the rear edge 208 (the angles therefore extend from -180° to +180°). The cable 302 is inserted into the handle 110 at an angle of 0° (the entry point of the cable 302 into the handle 110 is therefore at 0°). For each cross-section of the median line 610 that includes a portion of electrode 602, the electrode 602 extends at most over an area of ​​the handle between -45° and +90°, in particular between -30° and 80°. In one embodiment, the electrodes extend from -30° to +79° (total angle covered by the electrodes of 109°, plus or minus 1°).

[0098] This electrode positioning offers several advantages. When gripping the handle 110, the cable 302 generally remains downwards, aligned with the vertical Z. Consequently, firstly, with a natural and intuitive grip, the electrode positioning allows for optimized contact with the fingers, enabling contact between the electrodes and all fingers: the phalanges of the longest fingers, and the phalanges or phalanges of the shortest fingers. Secondly, by avoiding contact between the finger phalanges, the handle 110 can be used with rings. Thirdly, the electrodes are positioned downwards, i.e., they are oriented towards the ground: the weight of the handle, the cable, and possibly a cable tension force all contribute to maintaining contact between the electrodes and the fingers, which wrap under the handle 110 and thus over the electrodes.Fourth, the position of the four electrodes along direction A allows the electrodes to all be in contact with one hand as part of a natural and intuitive grip on handle 110.

[0099] The handle 110 may include a main body 404 on which the electrodes and other components (electronics, attachment, etc.) are mounted. The main body 404 may have an elongated shape along a longitudinal axis (which is parallel along the X direction in the stored position), for example, generally cylindrical and more specifically cylindrical of revolution. The shape is chosen to be easily grasped by a user. To facilitate assembly, the main body 404 may include a first part 702 and a second part 704. The first part 702 may receive the electrodes 402, and the second part 704 may be mounted on the first part 702. In particular, the second part 704 may include a cylindrical section (for example, of revolution) with two ends (for example, flat or rounded).A portion of the side wall of the cylindrical section may be omitted (for example, from one end to the other) in order to accommodate the first part 702 of the main body 404. A plastic material may be used for the main body, in order to keep the handle lightweight (in case of a fall) and to properly insulate the electrodes 402 from each other.

[0100] In one embodiment, the electrodes 402 are made in the form of several metallic inserts in the main body 404. Materials that can be used for the metallic inserts include stainless steel, titanium, brass, ITO (indium tin oxide), nickel (or nickel alloy), or conductive plastics. For signal processing and / or acquisition, particularly of ECG signals, the handle 110 may include processing electronics (amplification, filtering, etc.), especially for ECG. It is generally preferable to amplify the signal as close as possible to the electrodes because the cable can pick up ambient noise.

[0101] In the stowed position, the first part 702 is opposite the base 102 and the second part 704 is visible. The electrodes 402 are thus arranged against the handle support 112.

[0102] In one embodiment, the handle 110 is removable, particularly for repair purposes. To this end, the handle 110 includes a fastening system 604 for connecting said handle 110 to the cable 302. The fastening system 604 allows the handle 110 to be replaced without changing the cable 302. The fastening system 604 can be mounted in the first part 702 of the handle. This positions the electrodes on the side of the cable 302, ensuring a natural contact position between the electrodes 402 and the user's fingers. The fastening system 604 may include a jaw 606, 608 that fits around a stopper mounted on the cable 302.

[0103] In one embodiment, the balance support 112 and the handle 110 include a magnetic attachment system (for example, by means of at least one permanent magnet). A magnetic material is provided in the support 112 and a magnet is mounted in the handle 110 (or vice versa). The magnetic attachment systems also serve as a keying device when positioning the handle 110 on the handle support 112 (the left part of the handle cannot be placed on the right part of the handle support due to polarity differences). Neodymium magnets may be used.

[0104] As previously stated, the cable 302 can be stored in the base 102 (in stored position, visible in Figures 1 and 2) and be outside the base 102 (in deployed position, visible in [Fig.3]).

[0105] In order for the cable 302 to more naturally come into its stowed position, the end of the cable 302 attached to the handle 110 extends orthogonally with respect to a surface of the handle. In particular, the handle illustrated in the figures has a cylindrical shape: the cable 302 therefore extends radially with respect to the cylinder.

[0106] The change of position between a stowed and an extended position therefore implies a displacement of the cable 302 relative to the base. For safety and practical reasons, it is desirable that the cable 302 be almost entirely housed within the base 102 in the stowed position. To make this possible Without any particular effort from the user, a return mechanism 802 is mounted in the balance. In one embodiment, this return mechanism is a winder, meaning that the cable 302 winds and unwinds when the user prepares to use the handle 110. Figure 8 illustrates the positioning of such a winder 802 (shown without its cover) in the base 102. The winder 802 is, for example, mounted on the support plate 202, which may include a through opening 902 to house the winder (to minimize the thickness of the base 102). The winder 802 may include mounting tabs that are screwed to the support plate 202. The winder 802 includes, for example, a fixed portion and a moving portion, with a spring between the two to provide a return function when the handle 110 is in the extended position or in an intermediate position. Document WO2021 / 082876 describes an example of a winder mechanism integrated into a bathroom scale.

[0107] To guide the cable 302 between the reel 802 and the handle 110, different solutions are proposed, which can be implemented together or separately.

[0108] The measuring plate 106 includes a through-hole 1102 for the passage of the cable 302. The radial orientation of the cable 302 relative to the handle cylinder allows the cable to be inserted directly into the through-hole 1102 of the measuring plate 106. The through-hole 1102 is, for example, cylindrical (i.e., straight). The through-hole 1102 can be orthogonal to the measuring plate 106 (parallel to the Z-axis, and not at an angle) to facilitate pulling the handle 110; for example, a straight cylindrical shape. The through-hole 1102 can have a cross-section equivalent to that of the cable 302 (with a slight functional clearance). For example, the through-hole 1102 is cylindrical. For example, the maximum cross-sectional dimension of the hole is 2 cm² or 1 cm².

[0109] In particular, the support plate 202 and the measuring plate 106 each include a through hole 804 and 1102, opposite each other, for the passage of the cable 302.

[0110] The reel 802 winds and unwinds the cable 302 in the XY plane (essentially along Y) while the handle 110 (and therefore the part of the cable located outside the base 102) moves along the Z direction. Consequently, the cable 302 must make one or more changes of direction. Near the opening 804 in the support plate 202, a roller 1002 (or a pulley) is arranged to facilitate changing the direction of the cable 302 (and to prevent friction that damages the cable 302, the support plate 202, and / or the handle support 112, and hinders the winding and unwinding of the cable). The roller 1002 can be a rotating roller or simply a roller with a smooth coating. As illustrated in [Fig. 10] (which shows a portion of the support plate 202), the roller 1002 can be mounted on the support plate 202 (on the underside 1004, i.e., the side facing the from the ground when measuring station 100 is in the operating position). Roller 1002 is arranged to be, along the Z direction, between cable 302 and support plate 202 (or measuring plate 106). A second roller (not shown) may be provided between roller 1002 and reel 802 to channel the cable. The second roller may be arranged so that cable 302 is between this second roller and the measuring plate. Alternatively, the second roller is opposite the first roller 1002. Both rollers are thus on either side of cable 302 (along the Z direction). Instead of a roller, a pulley or any element performing a similar function may be used.

[0111] To limit friction when passing through the orifice 804 of the support plate 202 and to soften the angle made by the cable 302, the edges of the orifice are chamfered (chamfer 1006 visible in [Fig. 10]), at least on the side of the lower face 1004. Similarly, to limit friction when passing through the orifice 1102 of the measuring plate 106, the edges of the orifice 1102 are chamfered (see [Fig. 11]: chamfer 1106 visible on the upper face 1104 of the measuring plate 106, i.e. the visible face, on which the user places their feet). Since the measuring plate 106 can be made of glass and therefore sharp, the orifice 1102 is chamfered on both sides (see [Fig. 12], which shows a perspective magnification: chamfer 1202 visible on the lower face 1204 of the measuring plate 106, i.e. the invisible face, which is opposite the support plate 202).

[0112] In the example shown in the figures, the handle support 112 is a part attached, for example by gluing, to the upper face 1104 of the measuring plate. The handle support 112 has an elongated shape. The handle support 112 can form a cradle 1302, of the rounded cradle type. The cradle can have a shape complementary to a portion of the handle 110 (here the first part 702 of the handle 110). In the example shown in [Fig. 6B], the cradle 1302 is rounded around an axis of direction X. The handle 110, when positioned on the handle support 112, does not touch the measuring plate 106.

[0113] In order to ensure that the cable 302 is completely invisible in the folded position, the handle support 112 includes a through-hole 1304, opposite the hole 1102 in the measuring plate 106. The radial orientation of the cable 302 relative to the handle cylinder allows the cable to be inserted directly into the through-hole 1304 of the handle support 112. The through-hole 1304 is, for example, cylindrical (i.e., straight). The through-hole 1304 can be orthogonal to the measuring plate 106 (parallel to the Z-axis, and not at an angle), to facilitate pulling the handle 110; for example, a straight cylindrical shape. The through-hole 1304 can have a cross-section equivalent to that of the cable 302 (with a slight (functional set). For example, the through-hole 1304 is cylindrical. For example, the maximum cross-sectional dimension of the hole is 2 cm or 1 cm.

[0114] The through-hole 1304 is advantageously positioned at the bottom of the cradle 1302. The bottom of the cradle is defined as the lowest position along the Z direction, i.e., the position closest to the measuring plate 106. Furthermore, the through-hole 1304 can be centered in the cradle along the Y axis. The movement of the cable 302 from the through-hole 1304 of the handle support 112 can become somewhat more erratic due to the use of the handle 110 by a user. To further reduce friction, the through-hole 1304 of the handle support 112 is chamfered. In particular, the edges of the through-hole 1304 are chamfered in the Y direction and can also be chamfered in the X direction (even chamfered all the way around). A chamfer 1306 is thus provided on at least one of the two opposite edges along Y of the through orifice 1304.Similarly, a chamfer 1306 can thus be provided on at least one of the two opposite edges along Y of the through orifice 1304.

[0115] The cradle 1302 can extend over an angle at least equal to the negative value of the position of the electrodes 602 on the handle 110 with respect to the bottom of the cradle (which corresponds to the angular position of the through orifice 1304 and therefore of the location of the cable 302 in the figures, i.e. -30° in the illustrated example). In other words, in the given example, in a cross section (a YZ cutting plane), the cradle extends over 30° between its end and the bottom of the cradle (which here corresponds to the angular position of the through orifice 1304).By having a cradle that extends over an angular portion (around an axis parallel to the X direction) at least equal to that of the electrodes, the latter are invisible when the measuring station 100 is viewed from the posterior edge 208, which corresponds to its most frequent positioning for the user (since the anterior edge 206 is generally against a wall), because they are hidden by the cradle 1302 (see [Fig. 6B]). This concealment increases the retention of the measuring station 100 (i.e., the fact that most users of the measuring station 100 continue to use it after a given period) because the user does not feel they are using a product with a medical or paramedical appearance.

[0116] Similarly, the cradle can extend less than 90°, that is, at an angle of at most 90°, or even at most 60°, or even 45°, on either side of a bottom of the cradle (which is defined as 0° - the through-hole also being at 0°), so as not to hinder gripping the handle. Fingers can then slide under the handle to remove it from the handle support 11. The 45° angle allows for easier gripping while concealing the electrodes.

[0117] Thanks to the handle support 112, the design and manufacture of the measuring plate 106 are simplified. Except for the through-hole 1102, the measuring plate 106 can be similar to that of a measuring station without a handle (thus simplifying the processes for having several different models, with and without a handle, for example). Furthermore, by placing the handle 1120 on a handle support 112 located on the measuring plate 106, the handle 110 is easily grasped by a user, particularly by raising the stored position relative to the measuring plate 106 along the Z-direction. The cradle shape 1302 allows the handle 110 to be easily stored and thus avoids being placed on the ground where it could be damaged, or damage the base 102 or the ground on which it rests.The arrangement of the cable 310 in the vertical direction 2, in alignment with the through holes 1304 and 1102 of the handle support 112 and the measuring plate 106, helps to simplify the storage position of the measuring station 100 because it is sufficient to accompany the return force of the reel 802 for the handle 110 to be positioned in the cradle 1302 (in particular due to the positioning of the through hole 1304 at the bottom of the cradle 1302).

[0118] In the above description and in the figures, the handle support is continuous along the X direction. However, it can be discontinuous along this direction. For example, the cradle shape can be generated by two or three supports, at the ends and in the middle. This configuration, however, conceals the cable and the handle electrodes less.

[0119] Alternatively, the measuring station 100 does not include a handle support, and the handle is placed directly on the measuring plate 106. The latter can be machined or molded to have a shape that allows the handle 110 to be received and held in place. For example, a cradle shape can be made in the glass. The through-hole 1102 is then at the bottom of the cradle. The magnetic attachment system can then be provided in the handle and under the measuring plate.

[0120] In one embodiment, the measuring station 100 has a weighing function, in order to measure the weight and therefore the mass of a user. The sensors of the base 100 then include at least one weight sensor or one mass sensor. In particular, a known solution consists of using load cells, which convert a deformation of an element into an electrical signal. When the user steps onto the measuring plate 106, their mass generates a force that is absorbed by the measuring plate 106, then transmitted (directly by contact or indirectly via an intermediate part such as the support plate 202) to at least one load cell, and then the contact is taken over by the base 108 (or the feet for pedestal architecture). Four load cells can be provided, near each corner of the base 102. When the base 102 is not rectangular, the cells loads can be arranged regularly with respect to the geometry (for example with symmetry around median axes).

[0121] In an embodiment illustrated in Figures 8 and 9, the support plate 202 includes openings 812 suitable for housing (without contact) the load cells. In this way, the support plate 202 does not interfere with the transfer of force between the measuring plate 106 and the load cells.

[0122] However, in the sandwich architecture, the displacement in the XY plane of the moving assembly (measuring plate 106, support plate 202, and other components, particularly electronic ones) must be limited relative to the fixed assembly (essentially the base 108). This displacement limitation must not, however, affect the weight measurement; that is, it must not interact with the displacement along the Z direction nor absorb any force along the Z direction. Document PCT / EP2017 / 050178 describes a satisfactory solution to this problem. The present description proposes an alternative embodiment. The support plate 202 includes at least one island 808, for example, one island 808 per load cell (four in the figures, one near each load cell). Island 808 is a part of the support plate 202 which is connected to a main body 902 of the base of support plate 202 by an elastic member 904.The elastic member 904 serves to limit the displacement of the moving assembly in the XY direction while minimizing interference with the Z-axis movement. The elastic member 904 may include one or more legs extending between the island 808 and the main body 902 of the support plate 202. In the figures, each elastic member 904 comprises four identical legs. Each island 808 is housed in a through-hole formed in the main body 902. The island 808 may have a circular, square, rectangular, or other shape (polygonal, for example, or a shape of revolution), and the through-hole may have a similar shape but be proportionally larger.

[0123] Each island 808 includes an attachment hole 1402, for example in the form of a tapped hole, which is suitable for receiving a rod, for example a screw, which secures the base 108 to the island 808 (via an attachment hole 1502 in the base 108). The screw may be self-tapping. The attachment hole 1402 may be provided in a projection 1404, which allows both for limiting the length of the rod and for locally increasing the thickness of the island 808 (greater rigidity in the connection with the rod).

[0124] However, if a user grasps the measuring station 100 by the measuring plate 106 (which is part of the moving assembly), the entire weight of the fixed part will be transferred through the rod and the island 808. The elastic member(s) 904 are not, however, strong enough to withstand this force (it should be noted that they are not intended to interfere with the weight measurement). The support plate 202 and the base 108 therefore include a maximum displacement stop in the Z direction. As illustrated in Figures 14 and 15, The stop can take the form of an L-shaped leg 1504 of the base 108 (with a Z-shaped portion in a plane parallel to the XY plane), which cooperates with a receptacle 1406 of the support plate 202 that includes a portion in a plane parallel to the XY plane, so that a stop is activated when the Z-displacement is too large. For example, the permissible Z-displacement is less than 1 mm.

[0125] The mounting of the support plate 202 onto the base 108 can be achieved by positioning the support plate 202 (or more generally, the entire moving assembly) above the base. The attachment holes 1502 of the base and the attachment holes 1402 must then be aligned in pairs to allow the insertion of the rod (for example, to insert a screw). This alignment can add a few seconds to the operator's time. To simplify the process, the measuring station 100 can include a guide between the moving assembly and the fixed assembly. The guide can take the form of a guide rod 1408 extending in Z and suitable for cooperating with a guide hole 1506 of the base 108. The guide rod 1408 can be located close (at a distance D) to the attachment hole 1402 of the corresponding island 808 (for example less than 1 cm) so that the influence of manufacturing clearances is minimal.Similarly, the 1502 hole in the base 108 is close to the guide hole 1506 (the same distance D). The guide rod 1408 protrudes in Z relative to the level of the attachment hole 1402. In particular, even though the island 808 is configured to be fixed in XY movement to the main body 902, the elastic members 904 actually impart elasticity in XY; to counteract this undesirable movement which can disrupt the assembly, the guide rod 1408 is mounted on said island 808. The guide rod 1406 also allows the rotation of the island 808 to be blocked during screwing.

[0126] Conversely, the base 108 could have the guide rod and the island 808 the guide orifice.

[0127] An opening 1410 is provided near the island 808 to house the load cell, so that it is positioned between the measuring plate 106 and the base 108.

[0128] Figures 15 to 17 illustrate the base 108 or certain parts forming the base 108. In one embodiment, the base is a single piece (for example, made of metal to be sufficiently rigid). However, such a base is heavy and expensive. To overcome these difficulties, given the various functions of the base (structural support of the measuring station 100, aesthetic function, sealing function, function of joining the parts, weighing function, etc.), the base 108 can be made up of several parts. In the embodiment illustrated in the figures, the base 108 comprises at least one frame 1508 and a stiffening plate 1602.

[0129] The stiffening plate 1602, which extends in an XY plane, is disposed between the frame 1508 (or within an open volume defined by the latter) and the plate of Support 202. The load cells rest directly on the stiffening plate 1602, which provides the necessary rigidity for accurate weight measurement, even on soft (carpet, for example) or uneven (old parquet, for example) surfaces. The stiffening plate 1602 can be made of metal, such as steel or aluminum. Aluminum has the advantage of being lightweight. As illustrated in [Fig. 16], the stiffening plate 1602 has ribs 1604 that, with the same amount of material, increase the plate's rigidity. The ribs 1604 are extensions of the plate along the Z direction. For example, the stiffening plate 1602 can be divided into at least two flat areas 1606, 1608 offset from each other along the Z direction and connected to each other by the ribs 1604. The flat areas 1606, 1608 also allow for the definition of footprints to house the components of the measuring station.For example, the winder 802, which fits into the circular recess 1610 of [Fig. 16]. The thickness of the stiffening plate 1602 (including the ribs) can be between 5 mm and 15 mm, for example 10 mm. The material thickness can be between 0.5 mm and 2 mm, for example 1 mm.

[0130] The geometry of the ribs, and therefore of the flat areas 1606, 1608, depends on at least two factors: the mechanical stress factor and the space constraints. The ribs can be arranged in a grid pattern, maximizing the vertical (Z) portions that are resistant to bending, while leaving sufficient space in the Z direction to accommodate the components (in particular the winder 802).

[0131] The frame 1508 can be a single piece or itself composed of several parts. It has an aesthetic function (as a housing that conceals the internal components of the measuring station 100) and can also serve to secure the parts together. The frame 1508 is, for example, made of plastic (a lightweight material). As illustrated in Figures 15 and 17, the frame 1508 comprises a base 1510 (extending essentially in the XY plane) and a side wall 1702 (extending essentially in the Z direction from the edge of the frame 1508). The tab 1504 can extend from the frame 1508 (the base 1510 in particular). The 1504 leg then passes through a corresponding hole 1614 in the stiffening plate 1602. The attachment holes 1502 can also be mounted on the frame 1508, by being mounted for example on a spacer 1512 which extends in the Z direction from the bottom 1510.The spacer 1512 passes through a hole 1616 in the stiffening plate to come into contact with the island 808 for assembly.

[0132] The elements 1514 of the frame 1508 are heat-welded studs (illustrated in the molten position). In practice, they take the form of a plastic rod that is inserted into a corresponding through hole 1612 in the stiffening plate 1602. An operator or a machine then melts the end of the rod, which expands and holds the stiffening plate 1602 and the frame 1508 together (soldering). Alternatively, screws can be used.

[0133] As seen in [Fig. 2], the edge of the support plate 202 is recessed in X and Y relative to that of the base 108. Consequently, the interior of the support station 100 could be visible. To prevent this, the side wall 1702 may include a collar 1704 extending in a plane parallel to the XY plane from one end of the side wall 1702 towards the interior of the base 108. To help hold the stiffening plate 1602, the side wall 1702 may include a plurality of clips 1706 that clamp (by clipping) the stiffening plate 1602.

[0134] In one variant, the spacer 1512 is an independent part wedged between the frame 1508 (the bottom 1510 in particular) and the stiffening plate 1602. This allows the frame 1508 to be manufactured as a single piece by injection by allowing the movement of the injectors (otherwise the spacer blocks their passage).

[0135] Each pad 1514 is a thermal welding pad. It is a plastic part that is melted so that it changes shape and locks the part inserted onto it.

[0136] The frame 1508 may include the chamfer 204 which facilitates gripping the measuring station 100. The chamfer 204 is present between the bottom 1510 and the side wall 1702 and allows the passage of fingers.

[0137] The electronic circuit of the load cells may be that described in applications PCT / FR2013 / 051754 or PCT / FR2021 / 050661.

[0138] As mentioned previously, the measuring station 100, and more specifically the base 102, may include a display 114 configured to display information to the user. The display 114 is attached to the support plate 202. The measuring plate 106 is positioned above the display 114. In an embodiment illustrated in Figures 8 and 9, the support plate 202 includes a housing 810 suitable for receiving the display 114. In order for the display 114 to be invisible when not powered and visible when powered, the measuring plate 106 is treated differently between an area facing the display 114 and the rest of the measuring plate 106.

[0139] In one embodiment, the sensors 104 include electrically conductive paths 602 (called "electrodes") on the base 102 (see especially Figures 6 and 7). The electrodes 602 may be in the form of a metallic deposit on an upper face 1104 of the measuring plate 106. The upper face 1104 of the measuring plate 106 is defined as the face receiving the user's feet (the visible face). To ensure the electrical connection with the PCB, the electrodes 602 pass through an edge of the measuring plate 106 and extend to a lower face 1204 of the measuring plate 106. The edge of the measuring plate 106 may have a rounded shape to ensure proper metallic deposition and continuity. Electrical safety is ensured. Furthermore, a rounded edge prevents injury when handling the measuring station 100. By rounded, we mean an arc of a circle or similar shape. The rounded edge also simplifies metal deposition during manufacturing. Application FR2106653 describes these electrically conductive paths in detail.

[0140] The electrodes 602 are connected to the PCB via an electrical connector, which provides a connection between the electrically conductive path on the underside 1204 and the PCB mounted on the support plate 202. The switch 566 allows the electrodes to be connected and disconnected to the various systems (ECG acquisition system, impedance measurement system, ESC system, etc.). In this way, each electrode can have several different functions depending on the switching position of the switch 566. The switch 566 may, for example, include a plurality of switches controlled by the MCU.

[0141] The upper face 1104 of the base 102 comprises a left group LG of electrodes (intended to be in contact with the left foot) and a right group RG of electrodes intended to be in contact with the right foot. When the base 102 is placed in normal operating conditions, the user places their feet on a left part of the scale and a right part of the scale (with their toes on the display side 114). Figures 10 and 11 show electrically conductive paths L1, L3, L5, L7, L9, L1, L13, L15, L17 that form the electrodes of the left group LG of electrodes and electrically conductive paths R2, R4, R6, R8, R10, R12, R14, R16, R18, that form the electrodes of the right group RG of electrodes.

[0142] The electrodes of the base 102 can take the form of bands parallel to each other along the X direction (along the width of the base 102).

[0143] In the illustrated architecture, the pairs of paths L1 and L3; L15 and L17; R2 and R4; R16 and R18 are not independent but are permanently electrically connected, so that the base 102 effectively comprises seven independent electrodes in the left group LG and seven independent electrodes in the right group RG. These permanent electrical connections can be made via the electrical paths on the measuring plate 106 (for example, on the underside 1204, not shown) or via the PCB of the measuring station 100.

[0144] In one example, the electrically conductive paths of the upper face 1104 corresponding to the electrodes 1301-1312 have a dimension (on the upper face 1104) along the length Y of between 1.5 cm and 2 cm (for example, 1.7 cm); the spacing between two successive bands can be between 0.5 cm and 1 cm (for example, 0.85 cm); the electrodes can have a dimension along the width X greater than 10 cm. In particular, each group LG, RG can comprise at least four independent electrodes, notably to allow for IPG in the foot (two electrodes connected to the AC power source 560 and two electrodes connected to the voltmeter 562). In another embodiment, each group LR, RG may include at least two independent electrodes (to perform an ESC with anode / cathode and a high impedance electrode, or to perform a BIA or an IPG between the legs), or three independent electrodes.
