Description

The invention relates to the field of bedding and more particularly that of bed mattresses.

In the field of bedding, it is known to add to an existing bed and mattress monitoring devices to improve the comfort of the user. For example, FR 2,706,035 describes a device for monitoring the weight of a bed. EP 2 548 473 proposes a device for detecting the presence of moisture and mold in a bed. In general, these devices are intended to be used in specific contexts, for example in a hospital environment. They only allow to generate an alert in case of detection of a predetermined situation, in order to facilitate the work of the hospital staff. These devices are neither intended nor adapted for domestic operation.

FR 2 979 244 discloses a device for programming the bed temperature and ambient brightness, for example according to the sleep phases and wake phases desired by the user. But it ignores the principles governing human sleep generally accepted. He is therefore content to configure the device according to basic requirements such as the desired bedtime and sunrise schedules without taking into consideration the physiological constraints related to his sleep. The user does not have objective and specific information about his own sleep. He is therefore unable to monitor his sleep and identify any abnormalities. The influence of such devices on the quality of sleep and the comfort of the user is thus limited, when it does not have a detrimental effect. The invention improves the situation. The Applicant proposes a bedding mattress including a body having a top layer for supporting a user and comprising: - a controller, - a speaker housed in the body, - a vibrator integrated in the body, - a heating circuit and / or cooling housed in the body, and 5 - a set of sensors. The set of sensors includes: - a temperature sensor housed in the body and arranged to measure a temperature of the upper surface, - an electrode forming part of the upper surface of the body so as to be brought into contact with the user of the mattress and adapted to measure cardiac activity; a plurality of pressure sensors housed in the body, distributed in at least a portion of the upper surface and configured to detect and / or locate a user on the mattress; - a microphone arranged to capture the sound environment of the mattress, and - a brightness sensor arranged to measure the ambient brightness. The controller is connected to each of the sensor set sensors, loudspeaker, buzzer and heating and / or cooling circuit. The controller is further configured to: - transmit data from the sensor set to a remote processing unit via a communication network, - receive control data via the communication network, and - drive the built-in speaker, the vibrator, and the heating and / or cooling circuit according to the received control data. Such a mattress allows a long-term follow-up of a large number of parameters relating to the quality of sleep of an individual. This mattress also makes it possible to accurately determine the sleep characteristics of the user such as his 30 sleep cycles, his movements, his cardiac activity and his respiratory activity. All the data collected and stored can, if necessary, be transmitted to a health professional. The latter then has information of a high precision.

The mattress can be used in the familiar environment of the user, unlike surveillance provided in a health facility that disrupts natural sleep itself, simply because the user does not sleep under normal conditions. The data obtained with the mattress of the invention faithfully represent the habits and specificities of each user. The analyzes can be performed in real time as well as in the long term. The crossover, the processing and the analysis of the data also make it possible to propose an automated and personalized analysis. The results of the analyzes are then easily understandable by a user without professional or medical assistance. The mattress also makes it possible to drive finely and easily parameters influencing the user's sleep based on the data received and the analysis that is drawn from it. The control can be made fully automated and / or user-configurable. The user then becomes an informed actor of the improvement of his own sleep. Moreover, such a mattress is compatible with conventional domestic equipment. In particular, the mattress communicates via a data network, for example type 20 CPL, Wifi and / or cellular, with other electronic devices, for example of the type computer, tablet and / or ordiphone. The installation and commissioning of the mattress in a classic bedroom is quick and easy. The mattress may further comprise at least one USB socket formed in a free body surface. The processing unit can be configured to perform statistical processing of the data transmitted from the controller and deduce data representative of the sleep of the user of the mattress. According to another aspect of the invention, the Applicant proposes a bedding kit comprising a mattress as defined above and further comprising a blanket.

The cover supports at least one of the following: a loudspeaker, a buzzer, a heating and / or cooling circuit, and a sensor. The elements of the blanket comes in replacement or in addition to the equivalent elements of the mattress. The cover is intended to be connected to the mattress.

According to another aspect of the invention, the Applicant proposes a bedding kit comprising a mattress as defined above and further comprising at least one electrode capable of being connected to the mattress controller and to be placed by the user during bedtime. Such a kit may further include a cover.

Other characteristics, details and advantages of the invention will appear on reading the following detailed description, and the attached drawings, in which: FIG. 1 shows a perspective view of a mattress according to the invention; and - Figure 2 shows a communication diagram between a mattress according to the invention and other devices. The drawings and the description below contain, for the most part, elements of a certain character. They will thus be able not only to serve to better understand the present invention, but also to contribute to its definition, if necessary. Reference is made to FIG. 1. A mattress 1 comprises a body 3 having an upper layer 5 carrying a free surface for supporting a user. The mattress 1 further comprises a controller 7, two speakers 9, a vibrator 11 and a heating circuit and / or cooling 13. The body 3 is generally parallelepiped shape. The body 3 comprises an outer shell, here made of fabric, filled with a deformable material such as a foam and latex assembly. The lining of the body 3 of the mattress 1 is made in a manner known per se in the field of bedding. For ease of understanding, the terms head and foot refer to the two lateral faces of the body 3 furthest away from each other. In the example described here, the loudspeakers 9 are arranged in the upper layer 5 of the body 3 in the vicinity of the two head angles of the body 3. The two loudspeakers 9 allow, for example, to simultaneously broadcast two bands distinct sounds. By two soundtracks, we hear either two distinct melodies for two users of the mattress 1, or two complementary channels of a stereophonic soundtrack. Alternatively, the loudspeakers 9 can be used to perform an "active noise control" by broadcasting a wave of equal amplitude and phase opposite to that of the sound environment. Alternatively, the speakers 9 may be used to diffuse white noise. In variants, the mattress 1 comprises one or more than two loudspeakers 9. In other variants, one or more loudspeakers are arranged in one or more of the lateral faces of the body 3. In a variant, the speakers 9 are connected to the body 3 by a cable without being attached thereto. The user can then move the speakers 9 according to his wishes and the environment of the mattress 1. The vibrator 11 is integrated in the body 3. In the example described here, the vibrator 11 is disposed in the layer upper 5 of the body 3 and in half of the side of the foot of the body 3. In general, the configuration and positioning of the vibrator 11 in the body 3 are chosen so that the vibrations of the vibrator 11 are felt by a user lying on In variants, the mattress 1 comprises a plurality of vibrators 11. For example, a vibrator 11 may be disposed respectively in the one and the other of the lateral halves of the body 3. Thus, the vibrations of the One of the vibrators 11 is only felt by a user lying on the corresponding lateral half of the body 3. The separate activation of two vibrators 11 can allow the selective awakening of one or the other of two users lying down side by side.next to the mattress 1.

The heating and / or cooling circuit 13 is housed in the body 3. The heating and / or cooling circuit 13 comprises a coolant circuit forming a closed loop. The heat transfer fluid circuit is disposed in the upper layer 5 of the body 3. The heat transfer fluid circuit passes through a heat exchanger. The heat exchanger is here disposed at the foot of the body 3 and in communication with the outside. The heating and / or cooling circuit 13 is generally arranged so that the circulation of the coolant in the circuit allows the thermoregulation of the upper layer 5 of the body 3. The heat exchanger is said to be reversible and allows, as a function of control instructions, to heat or cool the coolant flowing therethrough. In the example described here, the coolant circuit of the heating and / or cooling circuit 13 extends substantially over half of the foot side of the body 3. The heating and / or cooling circuit 13 comprises, here , a power cord 15 extending beyond the body 3. The power cord is intended to be connected to the mains. In the case of a mattress 1 for supporting two users, the mattress may comprise two separate heating and / or cooling circuits 13 in order to vary the temperature on one side and the other of the body 3 almost independent. The loudspeakers 9, the vibrator 11 and the heat exchanger of the heating and / or cooling circuit 13 are each electrically connected to the controller 7. This connection is, here, provided by conducting wires housed in the thickness of the 3. The mattress 1 further comprises a set of sensors. The set of sensors includes: - a temperature sensor 21, - a cardiac electrode 23, - pressure sensors 25, - a microphone 27, and - a brightness sensor 29.

The temperature sensor 21 is housed in the upper layer 5 of the body 3. In the example described here, the temperature sensor 21 is disposed substantially in the center of the upper layer 5, a few centimeters below the free surface. The distance between the heating circuit and / or cooling 13 and the temperature sensor 21 is chosen large enough not to disturb the measurements. Direct contact between the temperature sensor 21 and the heating and / or cooling circuit 13 is avoided. Alternatively, the mattress 1 may comprise a plurality of temperature sensors 21.

For example, the mattress 1 may comprise as many temperature sensors 21 as users intended for the mattress 1. In this case, the arrangement of the temperature sensors 21 in the body 3 is defined according to the sleeping zones provided for each one. users.

Alternatively, the mattress 1 may comprise a number of temperature sensors 21 greater than the number of users provided for the mattress 1. The temperature sensors 21 are then distributed in the body 3 so as to record temperatures corresponding to predefined areas body 3 of the mattress 1.

The electrode 23 is substantially merged with the free surface of the upper layer 5 of the body 3. In the example described here, the electrode 23 has a flat shape and extends over an area of about 20 square centimeters. The electrode 23 is here fixed to the body 3 by means of a thermo-conductive adhesive. The electrode 23 is arranged to be brought into contact with the user of the mattress 1 and to measure its cardiac activity. In general, the electrode 23 is disposed in an area of the body 3 of the mattress 1 that can be brought into direct contact with the skin of the user without any fabric layer such as a sheet or a bottom night can interpose.

The pressure sensors 25 are housed in the body 3 of the mattress 1 and distributed in at least a portion of the upper layer 5. The arrangement of the pressure sensors 25 forms a detection matrix. Each pressure sensor 25 is associated with coordinates representative of its position relative to the body 3. The detection matrix arrangement makes it possible to detect the presence or absence of a person and also to locate a person on the free surface. of the upper layer 5 of the mattress 1. The pressure sensors 25 are here of the FSR type (for "Force-Sensing Re sistor"). They are equipped with a potentiometer for adjusting the hardness. Here they have a rounded shape and a diameter of about 15 millimeters. In variants, the pressure sensors 25 are distributed throughout the upper layer 5. In another variant, the pressure sensors 25 may be arranged to extend in a plurality of mutually spaced areas. For example, two sets of pressure sensors 25 can be provided at the sleeping positions of two users of the mattress 1. The microphone 27 is disposed in the body 3 of the mattress 1 and oriented to capture the sound environment of the mattress 1. In the example described here, it is arranged near one of the speakers 9. In general, the location of the microphone 27 relative to the body 3 of the mattress 1 is chosen so as to limit the risk of friction. sheets against the microphone 27 in order to avoid the disturbance of the measurements.

Alternatively, the microphone 27 may be connected to the body 3 by a cable without being attached thereto. This makes it possible to adapt the position of the microphone 27 according to the environment of the mattress 1. As a variant, the mattress 1 may comprise at least two microphones 27, in order to improve the accuracy of the measurements and to better locate the origin of the recorded sounds. The brightness sensor 29 is arranged to measure the ambient brightness of the mattress 1 without the measurement being disturbed by the presence of sheets, blankets or other obstacles. In the example described here, the brightness sensor 29 is attached to the end of a mobile arm itself attached to the body 3 of the mattress 1. Thus, the brightness sensor 29 can be maintained above the bed sheets .

Alternatively, the brightness sensor 29 may be connected to the body 3 by a cable without being attached thereto. This makes it possible to adapt the position of the brightness sensor 29 according to the environment of the mattress 1. The brightness sensor 29 comprises, here, a photoresistor. The photoresistor is coupled to a potentiometer to facilitate the calibration of the brightness sensor 29. Alternatively, the mattress 1 may comprise at least two brightness sensors 29. The controller 7 is connected to each of the sensors 21, 23, 25, 27 and 29, the loudspeakers 9, the vibrator 11 and the heating circuit and / or cooling 13. Here, the connections 10 are provided by son son. In the example described here, the controller 7 takes the form of an electronic box housed in the thickness of the body 3, for example near the foot of the body 3. The controller 7 comprises an electrical connection to a power source . Here, the connection to the power source is common with that of the heating and / or cooling circuit 13. In general, the controller 7 is arranged at a distance from the user's head lying on the mattress 1. The controller 7 comprises a processor and communication means. The communication means 20 comprise, in the example described here, wireless communication means. The communication means are configured to connect to a WiFi home wireless network. As a variant, the communication means comprise wireless telephony communication means, for example compatible GSM, GPRS, EDGE, 3G or LTE, telecommunication wire means such as an in-line carrier current network (PLC), means of satellite communications, or a combination of these means. The processor of the controller 7 is connected to the communication means. The processor of the controller 7 is configured to transmit data 101 from the set of sensors 21, 23, 25, 27 and 29 to a remote processing unit 91. The transmission of the data 101 to the processing unit 91 is carried out via a communication network 81.

FIG. 2 diagrammatically represents the data exchanges between the mattress 1 and the processing unit 91. The communication network 81 here comprises the Wifi home wireless network, the Internet network and the mobile telephone network. The controller 7 transmits the data 101 from the sensor set 21, 23, 25, 27 and 29 to a modem 71, for example to the modem 71 included in a domestic "Internet box", via the Wifi network. The modem 71 transmits the data 101 to the processing unit 91 via the Internet.

The remote processing unit 91 is, here, physically located at a service provider, away from the user's home. The processing unit 91 is connected to the Internet network. For example, the remote processing unit 91 may belong to a system called "in the cloud" ("Cloud").

The processing unit 91 receives, stores and processes the data 101 from the sensor set 21, 23, 25, 27 and 29. The processing unit 91 is, for example, configured to return the data 101 to connected devices. computer type, tablet and / or ordiphone, via corresponding communications networks. The forwarding can be direct and the raw data 101 is transmitted. The return can be indirect and the data is formatted before being transmitted. The processing unit 91 is further configured to analyze the data 101 and derive analysis data, representative of the use of the mattress 1. The analysis data can be transmitted to connected devices of the computer, tablet type. , ordiphone, via corresponding communication networks. Thus, a user can view the raw data and / or the analyzed data provided by the processing unit 91. The mattress 1 allows the user to better understand his own sleep, to detect and understand possible disorders.

In a variant, the processing unit 9 is configured to perform a statistical processing of the data 101 and to deduce representative sleep data from the user of the mattress 1.

The processing unit 91 is further configured to output control data 103 from the received data 101. The control data 103 is then transmitted via the communication network 81 to the controller 7 of the mattress 1. For example, if the temperature measured by the temperature sensor 21 is less than a predetermined temperature, the processing unit 91 may send in response a heating command for the heating and / or cooling circuit 13. The received control data 103 by the controller 7 are processed and interpreted to control the components of the mattress 1. Thus, the controller 7 controls the speakers 15 9, the vibrator 11 and the heating circuit and / or cooling 13 according to the control data 103 received from the processing unit 91. The data exchange 101, 103 between the controller 7 and the processing unit 91 can be performed at regular and predetermined intervals. ined. Alternatively, the data exchange 101, 103 can be realized in real time. Examples of use of the mattress 1 will now be described. The processing unit 91 analyzes in a combined manner the data from the pressure sensors 25 and the microphone 27. It derives information on the positions, the weight and the user's breathing of the mattress 1. The analysis of the data from the sensors includes, for example, filtering operations to distinguish the regular signals specific to the user's breathing and the sporadic movements and positional changes of this one during his sleep. The combination of the signals received from each of the pressure sensors 25 and the known position of each of the pressure sensors 25 makes it possible to deduce the positions adopted by the user during his sleep. The processing unit 91 is then able to draw visualization data. The visualization data are then transmitted to the connected devices of the computer, tablet, and ordiphone type.

The microphone 27 transmits data representative of the sound signals experienced, consciously or unconsciously, by the user of the mattress 1. The analysis of the data makes it possible, for example by means of signal processing algorithms, to estimate the level of discomfort. noise experienced by the user during sleep. This also makes it possible to define the repeatability of the detected events. Thus, it can be determined whether this discomfort is regular or accidental. This also helps to identify the source of the noise pollution. Noise pollution is understood to mean the snoring of the user himself or another user of the mattress 1.

Similarly, the light sensor 29 transmits data representative of the light pollution experienced by the user of the mattress 1. A corresponding analysis makes it possible to identify the sources of light pollution. The crossing of the measured data and their recording over predetermined times allow the processing unit 91 to calculate the usual sleep cycles of the user. The processing unit 91 is then able to propose models of thermoregulation of the mattress 1 and / or waking schedules adapted according to the sleep cycles.

By comparing and crossing the data from each of the sensors, the processing unit 91 determines the existence or otherwise of the absence of causal links between an event such as a noise and the data representative of the quality. some sleep.

The control of the loudspeakers 9, the vibrator 11, and the heating and / or cooling circuit 13 by the processing unit 91 via the controller 7, can be made fully automatic, that is to say without intervention. specific to the user. Alternatively, the control data 103 transmitted by the processing unit 91 can be made dependent on instructions transmitted by the user himself. For example, the user can set thermoregulation cycles of the mattress 1 according to the days of the week and / or time. The user can also program an alarm clock by means of the loudspeakers 9 and / or the vibrator 11 and / or the heating and / or cooling circuit 13 according to customizable criteria. These criteria can be chosen, for example from a fixed time and a time slot. In the case of a time slot, the processing unit 91 may transmit control data for triggering the alarm only when the following cumulative conditions are met: the current time is within the predefined time range, and, analysis of the received data 101 of the sensors indicates that the user is in a sleep phase conducive to a pleasant awakening. Typically, it is accepted that an awakening during a light sleep phase is preferable to an awakening during a deep sleep phase. The control also makes it possible to regulate the intensity of the vibrations, as well as their continuous or rhythmic character. Likewise, the piloting makes it possible to preset the soundtracks to be broadcast during the fall asleep and / or the awakening. It is also possible to combine the activation of the vibrator 11 and the speakers 9 so that the vibrations are produced according to the soundtrack. The raw data and / or the data resulting from the analyzes carried out by the processing unit 91 can be stored on any storage medium known as such.

Subsequent analyzes can thus be specifically requested from the processing unit 91. In addition, analyzes on the medium or long term evolution of the use of the mattress 1 can be made on the basis of the stored data. A history of the use of the mattress 1 is constituted.

In particular applications, the processing unit 91 can be programmed to trigger alerts when an unexpected presence is detected on the mattress 1 or on the contrary that an unexpected absence is detected on the mattress 1. For example, a user can be warned that a person lying on the mattress 1 is leaving the mattress. An alert can be transmitted via a smartphone and the corresponding communication network. Such applications facilitate the monitoring of third persons who are ill and / or disabled and / or elderly, especially when they are housed at home. In the example described here, the mattress 1 further comprises USB ports, referenced 31, formed in a side wall of the body 3 of the mattress 1. Such USB ports are connected to the controller 7 of the mattress 1. The user can then connect various electronic devices directly to the mattress 1, for example for charging the battery of a device or to control the controller 7 via a third device. In the embodiment shown in FIG. 1, the mattress 1 is designed to accommodate a single user. Alternatively, a mattress 1 can be configured to accommodate two users simultaneously. In this case, the sensors 21, 23, 25, 27, 29 may, if necessary, be split as mentioned above. The analyzes performed by the remote processing unit 91 are adapted accordingly.

Although the primary function of the mattress 1 is to improve the sleep of the user, such a mattress 1 can also be used to monitor a bedridden patient and / or sexual activity of the user and help improve the situation. In variants, the mattress is associated with a blanket or quilt. In this case, at least some of the sensors may be carried by the cover. A loudspeaker, a vibrator and / or a heating and / or cooling circuit can be housed in the cover. The elements carried by the cover can come in replacement or in addition to those of the mattress. In operation, the cover is connected to the mattress. The sensors and / or actuators of the cover are connected to the controller. The mattress and blanket can then be marketed separately or together, for example in the form of a bedding kit. For example, the cover houses a heating and / or cooling circuit.

In a variant, one or more remote electrodes adapted to be connected to the controller accompany the mattress. The remote electrodes then come in replacement or in addition to the electrode of the mattress. The remote electrodes are able to be placed by the user at bedtime. In this case, the good positioning in contact with the body is provided by the user. The remote electrodes can be included in a kit including the mattress, whether or not this kit includes the cover. The invention is not limited to the examples of mattresses and applications described above, only by way of example, but it encompasses all the variants that may be considered by those skilled in the art within the scope of the claims below. après.15
