The support part 30 may be a core component that is disposed inside the filler 20 to stably support the user's head and neck (or cervical spine).

On the other hand, the support portion 30 of the functional pillow 100 of the present invention may be provided with a "dual core", in a little more detail, between the first core 31 and the second core 32 and the two It may include a connection part 33 that is arranged and connected, and may be characterized in that the sizes of the first core 31 and the second core 32 are different. For example, according to a design request, the first core The size of (31) is larger than the size of the second core (32), and the maximum height of the first core (31) in the vertical direction (refer to (a) of FIG. 3) may be 5.5 cm, and the size of the second core (32) The maximum height in the vertical direction (refer to (b) of FIG. 3) may be 3.5cm, but is not limited thereto.

Accordingly, the first core 31 and the second core 32 may be selected and used by changing the arrangement of the functional pillow 100 of the present invention according to the user's body shape and the support strength according to the user's condition.

In more detail, if the user is an adult or the user wants solid support and active cervical vertebrae correction, the functional pillow 100 of the present invention is arranged so that the first core 31 corresponds to the user's neck (that is, the connection part 33 ), the first core 31 is arranged to support the cervical spine while supporting the head), and can be used according to the user's body shape and condition.

On the contrary, if the user is an infant or child or the user desires soft support and comfort, the second core 32 of the present invention is arranged to correspond to the user's neck (ie, the connection part 33). The second core 32 is arranged to support the cervical spine while supporting the head), and can be used according to the user's body shape and condition.

On the other hand, the first core 31 and the second core 32 and the connection portion 33 may have a form extending horizontally along the horizontal side of the functional pillow 100 of the present invention, and the connection portion 33 To support the head, the upper and lower surfaces may have a plate shape, and the first core 31 and the second core 32 have rounded corners in the vertical section to minimize neck tilt and reduce shoulder pressure. It can be in the shape of an octagon.

On the other hand, according to this form, it is possible to induce a comfortable sleep by stably supporting the user's head and neck regardless of whether the user's posture is lying down, prone, or lying on its side, without restricting the user's posture tightly. have.

Meanwhile, another embodiment of the support part 30 in the functional pillow 100 shown in FIG. 4 is shown.

According to another embodiment, the height of the first core 31 and/or the second core 32 constituting the support part 30 can be adjusted, and in FIG. 4, the height of the first core 31 as an example Showing control.

The first core 31 having an octagonal shape has a hollow interior, and at least two hinges 31a are connected to one side of the cover type having a certain thickness, and the connection part 33 has a first core. At least two or more fixing grooves 33a are formed close to (31).

The fixing groove (33a) is formed along the width direction of the connection portion (33), it is formed by a predetermined distance apart in the length direction.

Therefore, if the height of the first core 31 is lower according to the user's preference, the upper surface of the first core 31 facing the first core 32 is lifted, and the hinge 31a is rotated to close the fixing groove. By positioning it at (33a), the height of the first core 31 is lowered.

The height of the first core 31 decreases as it is mounted in the fixing groove 33a away from the first core 31.

In addition, in a modified example (not shown) of the functional pillow 100 of the present invention, the occipital support can be popped up from the connection part 33 according to the user's button operation, and accordingly, the user can support the occipital part above a certain height. You can sleep comfortably in the state (if the user feels uncomfortable that the head is supported by the flat plate of the existing connection, the occipital support can be popped up).

In addition, in a modification (not shown) of the functional pillow 100 of the present invention, the support part 30 is formed of a transparent or translucent material, and a lamp is built into the support part 30 to emit light according to the user's operation. Accordingly, the position and shape of the support part 30 can be guided to the user. In this case, the lamp emits light for a certain period of time by the timer function and then turns off, so that the user's sleep may not be disturbed.

In addition, in a modified example (not shown) of the functional pillow 100 of the present invention, a hinge driven by an actuator (for example, a rotary motor) may be provided in the center of the connection part 33, and accordingly, the connection part 33 ) Is tilted by the user's manipulation so that the inclination angle can be adjusted. On the other hand, the actuator is also provided with a timer function so that after the user goes to sleep, the connection part 33 is returned to its original shape in the form of an original horizontal plate, so that the user can sleep in a comfortable position. That is, in the modified example of the functional pillow 100 of the present invention, in consideration of the user who is trained in a poor posture, the connection part 33 maintains a certain inclination angle when the user sleeps, and after the user sleeps, the horizontal plane It can be guided to go back to and sleep in a correct posture. In this case, in order to prevent the user from waking up, the return operation of the actuator may be performed at a slower speed than the operation by the user's operation.

In addition, in a modified example (not shown) of the functional pillow 100 of the present invention, a pressure sensor and a heating wire are embedded in the first core 31 and the second core 32, so that the user can As the 2 core 32 is selected, it senses that pressure is applied by the user's neck and operates the heating wire of the corresponding core, thereby providing a function of steaming the user's neck during sleep.

Further, in a variant (not shown) of the functional pillow 100 of the present invention, a strain gauge is built into the support part 30, and in the strain gauge, an electronic signal when a deformation exceeding a predetermined value occurs in the support part 30 due to frequent use. By automatically illuminating the lamp through the user can be informed of the replacement timing.

In addition, in a modified example (not shown) of the functional pillow 100 of the present invention, a communication module capable of short-range communication may be further included, and the communication module communicates with the user's terminal using the functional pillow 100 Can be done. The communication module may be embedded in the support 30, for example, may be embedded in one of the first core 31 and the second core of the support 30.

Such a communication module may perform communication with the user's terminal through the installation of an application for managing the user's sleeping posture pattern that can be installed on the user's terminal. In particular, the communication module may perform communication with an external device (eg, a user's terminal (smart phone, etc.)) based on a short-range method. In this case, the communication module may perform communication in a Bluetooth Low Energy (BLE) method performed with low power among Bluetooth methods.

Specifically, the communication module may acquire information about the pressure sensed through the pressure sensor from the pressure sensor, and transmit information about the acquired pressure to the user's terminal. Accordingly, the user's terminal may provide the user's sleeping posture pattern according to the information on the pressure sensor to the user based on an application for managing the user's sleeping posture pattern installed in the user's terminal.

For example, the user may change his or her posture during sleep by using the functional pillow 100 of the present invention, and the pressure sensor may accumulate and store information on pressure sensed in real time during the user's sleep time. Thereafter, the pressure sensor can transmit information on the accumulated pressure to the communication module, and the communication module transmits the information on the pressure information to the user's terminal, thereby generating a posture pattern when the user sleeps in the application installed on the user's terminal. can do.

Through this method, the functional pillow 100 of the present invention can implement the Internet of Things (iOT) by performing short-range communication between the communication module and the user terminal during sleep. In addition, the communication module included in the functional pillow 100 of the present invention may have the structure shown in FIG. 4 and may be described in detail below.

Figure 5 is a block diagram showing a communication module of the functional pillow of the present invention.

Referring to FIG. 5, it may mean a communication module 40 included in the functional pillow 100 of the present invention. The communication module 40 included in the functional pillow 100 of the present invention may include at least one processor 41, a memory 42, and a network interface device 43 connected to a network to perform communication.

In addition, the communication module 40 included in the functional pillow 100 may further include an input interface device 44, an output interface device 45, a storage device 46, and the like. Each of the components included in the communication module 40 may be connected by a bus 47 to perform communication with each other.

The processor 41 may execute a program command stored in the memory 42 and/or the storage device 46. The processor 41 is a method of determining a user's sleeping posture pattern in a central processing unit (CPU), a graphics processing unit (GPU), or the functional pillow 100 according to the present invention (ie, It may refer to a dedicated processor in which a plurality of steps for (a method of transmitting information on the pressure sensed by the functional pillow during sleep) are performed. The memory 42 and the storage device 46 may be formed of a volatile storage medium and/or a nonvolatile storage medium.

For example, the memory 120 may be composed of read only memory (ROM) and/or random access memory (RAM). Here, the program command executed through the processor 110 is a plurality of performing the method of determining the posture pattern during sleep of the user of the present invention (that is, a method of transmitting information on the pressure sensed from the functional pillow during sleep). May include steps

And, Figure 6 shows a block diagram showing a smart sleep assistance system according to an embodiment of the present invention.

The smart sleep assistance system 500 of the present invention includes a functional pillow 100, a processor 510, a transceiver 520, a plurality of pressure sensors 530, at least one moisture detection sensor 540, a management server 550 , User terminal 560, camera module 570, and / or may include a smart bed 580. For example, a plurality of pressure sensors 530 and moisture detection sensors 540 may be attached to or embedded in the functional pillow 100.

At least one moisture detection sensor 540 may be embedded in the functional pillow 100 to detect moisture, humidity, moisture, and the like. For example, the moisture detection sensor 540 may measure the degree of drooling or the amount of drooling while the user puts his head on the functional pillow 100 while sleeping. To this end, the moisture detection sensor 540 may be built in a position close to the cover in the functional pillow 100.

On the other hand, when the moisture detection sensor 540 always detects moisture, humidity, moisture, etc., this is not information on saliva spilled while the user is sleeping, but rather the humidity in the air at the place where the functional pillow 100 is located. It can be something to measure. Therefore, the moisture detection sensor 540 a) detects moisture, humidity, moisture, etc. when a pressure higher than the critical pressure is sensed by the pressure sensor 530, and/or b) normal time (eg, sleep time). The humidity offset value from the humidity obtained when the normal humidity detected at a specific time except for a specific time period, 1 pm to 6 pm, 6 pm to 8 pm, etc.), and the humidity rises above the threshold value than the normal humidity The value of subtracting (subtracting) can be obtained as the measured humidity value or the degree of drooling or the amount of drooling. The normal humidity may be set differently by the processor 510 according to the season and/or the place where the functional pillow 100 is located.

In addition, the functional pillow 100 may further include a salt density sensor (not shown). The processor 510 further considers information on moisture, humidity, moisture, etc. detected by the moisture detection sensor 540 as well as salinity information measured by the salinity measurement sensor to determine the degree of drooling or the amount of saliva. You can get information about it. As an example, the salinity measurement sensor a) detects salinity, etc. when a pressure higher than the critical pressure is sensed by the pressure sensor 530, and/or b) at peacetime (e.g., at a specific time excluding sleep time, 1 pm A value obtained by subtracting (subtracting) the salinity offset value from the salinity obtained when the salinity detected during normal time is acquired at a time of 6 PM, 6 PM to 8 PM, etc. Can be obtained as the measured salinity value or the degree of drooling or the amount of drooling.

There may be cases where the user drools and sleeps due to a simple sleeping habit, but it can also be seen as a sign of abnormal health. For example, there may be cases of sleeping with drool due to incorrect sleeping postures, such as sleeping on your stomach or bending your head because the pillow is too high, but it may be due to some disease. If the user drools while sleeping, there is a high possibility of breathing through the mouth rather than through the nose.However, oral breathing can occur when air is difficult to pass through the nose due to nasal diseases such as rhinitis or sinusitis. In addition, when suffering from oral or gastrointestinal diseases such as gum disease, salivation may flow during sleep as the secretion of saliva increases abnormally, and swallowing disorders caused by abnormalities in the function of the throat or esophagus may also be the cause. In addition, when the ability to swallow food declines, a habit of drooling can occur.

In consideration of this point, the present invention proposes the following features.

The processor 510 may output healthcare information in consideration of at least one of normal humidity, measured humidity, normal salinity, measured salinity, degree of drooling, and/or amount of drooling. Here, the healthcare information may include first healthcare information instructing correction of a user's sleeping posture and/or second healthcare information indicating an abnormal signal for the user's health. For example, the first healthcare information may include information that the size of the smart pillow 100 does not fit the user and/or information that the user's sleeping posture is wrong or needs correction. As another example, the second healthcare information may include information on nose-related diseases such as rhinitis and sinusitis, information on oral diseases such as gum disease, information on gastrointestinal diseases, information on swallowing disorders, and/or digestive function. Information indicating that there is an abnormality may be included.

In addition, the processor 510 outputs the first healthcare information when at least one of the measurement humidity, the measurement salinity, and the degree of drooling (and/or the amount of drooling) exceeds the first healthcare information threshold. 2 When the healthcare information threshold is exceeded, the second healthcare information may be output. Here, the second healthcare information threshold may represent a humidity and/or salinity greater than the first healthcare information threshold.

In addition, the smart sleep assistance system 500 may further include a smart band (not shown) that the user can wear on a wrist or the like. The smart band may be implemented in the form of a smart watch or a smart bracelet. The smart bed 580 may include a first smart watch location sensor on the left side and a second smart watch location sensor on the right side with the user's lying position as a central axis. In addition, the smart band, the first smart watch location sensor, and the second smart watch location sensor use short-range communication technologies such as WiFi (Wireless Fidelity), Zigbee, NFC (Near Field Communication), Bluetooth, and BLE (Bluetooth Low-Energy). Each may include a communication unit that can be implemented, and through the short-range communication technology, the smart band, the first smart watch location sensor, and the second smart watch location sensor may transmit and receive predetermined signals/information with each other.

In addition, the first smart watch location sensor and the second smart watch location sensor include a smart band, a first smart watch location sensor, and a second smart watch location sensor through signals/information transmitted and received between the smart band (the smart bed). Information indicating whether it is located on the left side or information indicating whether it is located on the right side with respect to the central axis (of 580) may be generated. In addition, the first smart watch location sensor and the second smart watch location sensor provide information indicating whether the smart band is located on the left or on the right with respect to the central axis (of the smart bed 580). ).

The processor 510 indicates that the user takes a sleep while looking at the left direction based on the central axis based on information indicating whether the smart band is located on the left side with respect to the central axis (of the smart bed 580). First sleep posture information is generated, and based on information indicating whether the smart band is located on the right side with respect to the central axis (of the smart bed 580), the user can sleep while looking at the right direction based on the central axis. It is possible to generate second sleeping position information indicating that you are taking.

In addition, the processor 510 determines whether at least one of measurement humidity, measurement salinity, and degree of drooling (and/or amount of drooling) exceeds a first healthcare information threshold, and the first sleep posture information or the second Outputs the first healthcare information in consideration of sleep posture information, and calculates the second healthcare information in consideration of whether it exceeds the second healthcare information threshold and the first sleep posture information or the second sleep posture information. Can be printed. For example, the first healthcare information may further include information indicating that the user lies in one direction and/or posture correction information/alarm signal indicating that the user should sleep in a normal position.

The processor 510, the transceiver 520, the plurality of pressure sensors 530, and the moisture detection sensor 540 are modularized as one detachable part and can be embedded in the functional pillow 100, as well as the functional pillow. It may be detachable from (100). To this end, each of the detachable part and the functional pillow 100 may further include a coupling member corresponding to each other.

When the processor 510 is a modular detachable part (including a processor 510, a transceiver 520, a plurality of pressure sensors 530, and a moisture detection sensor 540) is separated from the functional pillow 100 Or, by recognizing that the coupling member is separated, information indicating that the smart pillow 100 has been washed once and/or information for counting the number of washing (or additional counting) may be generated.

The processor 510 may record/store the time point and/or the number of times the number of washing is counted (or additional counting), and the interval between the times of counting the number of washing (or additional counting) exceeds the washing interval threshold. In this case, the information/alarm signal indicating that laundry for the smart pillow 100 is required may be controlled to be output through the management server 550 and/or the user terminal 560.

And, the smart bed 580, for example, a) a mattress that provides a cushion having an elastic force and includes a plurality of springs and a plurality of hot wire modules; b) a lower support member for supporting the mattress; c) a head support member that provides a cushion while in contact with one side of the mattress; d) a rail member located above the head support member; e)

It may include.

Here, each of the plurality of flexible springs SPR1-1, SPR1-2, SPR1-3, SPR1-4, SPR1-5, ...) included in the first layer L1 has a central portion relative to both side portions. It can be configured to have a strong elastic force. Therefore, each of the plurality of soft springs (SPR1-1, SPR1-2, SPR1-3, SPR1-4, SPR1-5, ...) supports most of the body weight of a person in the central part, and both side parts of the soft spring Can be configured to support a person's body weight in an auxiliary manner.

In addition, each of the plurality of soft splings (SPR1-1, SPR1-2, SPR1-3, SPR1-4, SPR1-5, ...) has an elliptical shape with a relatively larger radius of curvature than both sides And, both side portions may be configured in a circular shape with a radius of curvature relatively smaller than the center.

In addition, on both side portions of each of the plurality of flexible springs (SPR1-1, SPR1-2, SPR1-3, SPR1-4, SPR1-5, ...), noise generated during the contraction or relaxation process according to the elastic force is A cushioning preventive member may be combined.

Meanwhile, the second layer L2 may further include hydraulic modules OM for contracting or relaxing the plurality of rigid springs SPR2, .... Here, the hydraulic module OM is a contact pad PD having an area equal to or larger than one side of the rigid spling so that the entire rigid spring can be contracted or relaxed, and the contact pad PD is pushed out by hydraulic pressure. A rod-shaped piston rod (RD) and a part of the piston rod RD are accommodated on one side, and the piston rod RD is connected to one side by using hydraulic distribution of two hydraulic openings (ETA, ETB). It may include a hydraulic cylinder (CLD) pushed by.

The contact pad PD may have a circular shape or an elliptical shape corresponding to one side portion of the rigid spling.

In addition, in the hydraulic cylinder (LCD), a piston (PST) dividing the space of the hydraulic cylinder (LCD) into two while making a linear motion of the hydraulic cylinder (CLD) while in contact with the piston rod (RD), and the piston (PST) are interposed therebetween. It may include two hydraulic openings (ETA, ETB) disposed on one side of the hydraulic cylinder (LCD). When hydraulic pressure is injected into the first hydraulic opening ETA among the hydraulic openings ETA and ETB, the piston PST moves to the second hydraulic opening ETB and relaxes the piston rod RD, and the second hydraulic opening When hydraulic pressure is injected into the (ETB), the piston rod RD may be relaxed while the piston PST moves to the first hydraulic opening ETA.

Meanwhile, the plurality of rigid springs SPR2, ... included in the second layer L2 are a plurality of flexible springs SPR1-1, SPR1-2, SPR1- included in the first layer L1. 3, SPR1-4, SPR1-5, ...) can be configured to have a relatively stronger (for example, more than two times) elastic force. Accordingly, the rigid springs SPR2, ... included in the second layer L2 are contracted or relaxed by the hydraulic module OM, and the flexible springs SPR1 indirectly contacting through the flexible member PLT. -1, SPR1-2, SPR1-3, SPR1-4, SPR1-5, ...) can be pushed out or relaxed. In addition, when the flexible springs (SPR1-1, SPR1-2, SPR1-3, SPR1-4, SPR1-5, ...) are contracted by a human body load, such contraction load is a flexible member (PLT) Since it is transmitted to the rigid springs through the rigid springs (SPR2, ...), when the degree of contraction of the rigid springs SPR2,...

In one embodiment of the present invention, since one hydraulic module (OM) is coupled to each of the plurality of rigid springs (SPR2, ...), the contraction or relaxation of the rigid springs (SPR2, ...) is individually Can be controlled.

In addition, the second layer L2 may further include a cylindrical member PP surrounding the rigid springs from the side. The cylindrical member PP may guide the rigid springs to move in the vertical direction. In addition, the cylindrical member (PP) is configured to match the shape of the side surface of the hydraulic cylinder (CLD) included in the hydraulic module (OM), so that the hydraulic module (OM) and the cylindrical member (PP) are configured to form one outer shape. I can.

In addition, an elastic sensing module SS may be coupled to an outer side of the cylindrical member PP. The elastic sensing module SS may detect an elastic change (more specifically, a vertical movement distance) of rigid springs in the cylindrical member PP. For example, as the elastic sensing module SS, a position detection sensor, a magnetic sensor, an ultrasonic sensor, or the like may be used.

In addition, the cylindrical member PP may be made of a transparent material such as transparent plastic or tempered glass. As such, since the cylindrical member (PP) is made of a transparent material, even if the elastic sensing module (SS) is coupled to the outer side of the cylindrical member (PP), the elastic change of the rigid springs inside the cylindrical member (PP) can be easily detected. I can.

Each of the rigid springs may be disposed to overlap with some of the flexible springs through the flexible member PLT. For example, referring to FIG. 7, the rigid spring SPR2 may be disposed to overlap with the four flexible springs SPR1-1, SPR1-2, SPR1-6, and SPR1-7 at the same time. The human body load does not appear as a contraction of one soft spring, but as a simultaneous contraction of several soft springs. Accordingly, in an embodiment of the present invention, it is possible to detect that the four flexible springs are contracted by a human body load through contraction of one rigid spring.

8 is a block diagram illustrating a block for sensing and controlling rigid springs included in the second layer of FIG. 7.

Referring to FIG. 8, the elastic sensing unit 720 is connected to the plurality of elastic sensing modules SS for sensing the elastic force of the plurality of rigid springs according to FIG. 6 by wire or wirelessly, so that the plurality of elastic sensing modules SS You can convert the data transmitted from

For example, when each of the plurality of elastic sensing modules (SS) transmits the current length of the rigid spring according to the detection of the elastic force of the rigid spring to the elastic sensor 720, the elastic sensor 720 is The initial length of the rigid spring set in advance can be compared with each other and converted into a contracted or relaxed length of the rigid spring.

In addition, the elastic control unit 710 physically controls hydraulic pressure flowing into the two hydraulic openings ETA and ETB included in the hydraulic module OM that controls the contraction and relaxation of each rigid spring according to an external elastic control command. Can be adjusted by Specifically, the elastic control unit 710 may physically adjust the hydraulic pressure of the hydraulic module OM to control contraction or relaxation of a rigid spring disposed at a position corresponding to a position coordinate included in the elastic control command.

FIG. 9 is a diagram illustrating a view of the first layer of FIG. 7 viewed from above.

9, a plurality of flexible springs (SPR1-1, SPR1-2, SPR1-3, SPR1-4, ...) included in the first layer (L1) is a smart bed (580) in the form of a square grid. ) Can be placed inside the mattress.

In addition, the first second L1 may further include a plurality of hot wire modules HL1, HL2, HL3, .... The plurality of hot wire modules (HL1, HL2, HL3, ...) are flexible springs (SPR1-1, SPR1-2, SPR1-3, SPR1-4, ...) to prevent damage to the hot wire module. It can be arranged in the form of a square grid so as not to overlap with. For example, each of the hot wire modules HL1, HL2, HL3, ... may be disposed so as not to overlap with the four flexible springs in the center of the four flexible springs arranged in a square shape.

Meanwhile, the plurality of hot wire modules HL1, HL2, HL3, ... may be configured as independent wires by separating physical wires from each other. For example, each of the plurality of hot wire modules HL1, HL2, HL3, ... may not be physically connected to each other. In this way, when a plurality of hot wire modules (HL1, HL2, HL3, ...) are independently configured, there is an advantage that it is possible to independently control the temperature between the four flexible springs. In this case, referring to the arrangement structure of the rigid springs shown in FIG. 6, one heating module disposed between the four flexible springs may be disposed to overlap with one rigid spring in a vertical direction. Accordingly, there is an advantage in that the position coordinates that detect the contraction or relaxation of one rigid spring can correspond to the position coordinates of one hot wire module as it is.

In addition, as a means for independently controlling a plurality of hot wire modules HL1, HL2, HL3, ... shown in FIG. 9, the wiring may be performed as follows. For example, among the plurality of heat wire modules (HL1, HL2, HL3, ...), the heat wire modules located in the same row may be connected to the same high voltage input terminal (IPTA1, IPTA2, ...), and a plurality of heat wire modules Among them, the hot wire modules located in the same row may be connected to the same low voltage input terminals (IPTB1, IPTB2, IPTB3, IPTB4, ...).

For example, in FIG. 9, the second column module HL2 located in the first row and the second column (ie, position coordinates (1, 2)) is the first among a plurality of high voltage input terminals (IPTA1, IPTA2, ...). It may be connected to the first high voltage input terminal IPTA1 connected to the row, and may be connected to the second low voltage input terminal IPTB2 connected to the second column among a plurality of low voltage input terminals IPTB1, IPTB2, IPTB3, IPTB4, ...

As such, the plurality of heat wire modules (HL1, HL2, HL3, ...) are arranged in a square grid shape like the flexible springs, so they can be divided into rows and columns, and the heat wire modules located in the same row have the same high voltage input terminal and The heat wire modules located in the same row may be independently controlled by the heat wire controller 810 in a manner connected to the same low voltage input terminal.

The high voltage input terminal selection unit 820 may select a high voltage input terminal corresponding to the row coordinates according to the row coordinate data received from the column control unit 810 and apply a high voltage power VH to the selected high voltage input terminal.

The low voltage input terminal selection unit 830 may select a low voltage input terminal corresponding to the column coordinate according to the column coordinate data received from the hot wire controller 810 and apply a low voltage power VL to the selected low voltage input terminal. In this case, the low voltage power supply VL may include a ground.

The column control unit 810 may transmit row coordinate data to the high voltage input terminal selection unit 820 and transmit column coordinate data to the low voltage input terminal selection unit 830 with reference to the location coordinates included in the external temperature control command. have.

Each of the plurality of hot wire modules (HL1, HL2, HL3, ...) is connected to the high voltage power supply (VH) from the high voltage input terminal selection unit 820 and the low voltage power supply (VL) from the low voltage input terminal selection unit 830 , Heat may be generated by a current flowing from the high voltage power supply VH to the low voltage power supply VL.

Hereinafter, the positional coordinates of the elastic data may be defined as rows and columns as the positional coordinates at which the rigid springs are located when viewed from the top of the mattress of the smart bed 580 unless there is a specific limitation.
