When it is determined that the user's head is placed on the pillow 1, the pillow 1 vibrates at a frequency of, for example, several times per minute. When the pillow 1 vibrates, the user's head also vibrates. The vibration of the head puts the user in a relaxed state and makes it easier to fall asleep.

The pillow 1 may have, for example, a cylindrical shape having two elliptical bottom surfaces, as shown in FIG. However, the shape of the pillow 1 is not limited to the cylindrical shape. For example, the shape of the pillow 1 may be a rectangular parallelepiped shape, a U-shape, a donut shape, or the like.

The vibration unit 10, the detection unit 11, the control unit 20, and the airbags 31 to 34 are covered with the exterior unit 15. The number of airbags included in the pillow 1 is not limited to four airbags 31 to 34. The number of airbags included in the pillow 1 may be 3 or less, or 5 or more. Hereinafter, when the airbags 31 to 34 are not particularly distinguished, they are simply referred to as "airbags 30".

As shown in FIG. 2, the vibrating portion 10 is arranged near the center of the pillow 1. The vibrating unit 10 comes into contact with, for example, airbags 31 to 34. The vibrating unit 10 vibrates the airbags 31 to 34 based on the electric signal from the control unit 20. The vibrating unit 10 vibrates the pillow 1 by vibrating the airbags 31 to 34. The vibrating portion 10 may be arranged at any position in the pillow 1. In this case, the vibrating portion 10 may be in contact with at least one of the airbags 31 to 34.

The vibrating unit 10 may include, for example, an air pump. In this case, the vibrating unit 10 vibrates the airbag 30 by varying the amount of air in the airbag 30 by an air pump based on an electric signal from the control unit 20. Alternatively, the vibrating unit 10 may be configured to include an electromagnetic actuator. In this case, the vibrating unit 10 vibrates the airbag 30 by driving the electromagnetic actuator based on the electric signal from the control unit 20.

The detection unit 11 is arranged in, for example, the exterior unit 15. The detection unit 11 may be in contact with the mounting surface A or may be arranged near the mounting surface A. The detection unit 11 includes, for example, a motion sensor. The motion sensor is configured by combining, for example, an acceleration sensor, a gyro sensor, and the like. The detection unit 11 detects the movement of the pillow 1 by the motion sensor. The detection unit 11 outputs the detected movement of the pillow 1 to the control unit 14, which will be described later.

The detection unit 11 may be configured to include a weight sensor. In this case, the detection unit 11 detects the weight applied to the pillow 1 by the weight sensor. The detection unit 11 outputs the detected weight to the control unit 14, which will be described later.

The detection unit 11 may be configured to include a proximity sensor. In this case, the detection unit 11 detects the presence of an object close to the pillow 1 in a non-contact manner by the proximity sensor. The detection unit 11 notifies the control unit 14, which will be described later, of the existence of an object close to the detected pillow 1.

The detection unit 11 may be configured to include a temperature sensor. In this case, the detection unit 11 detects the temperature of the pillow 1 by the temperature sensor. The detection unit 11 outputs the detected temperature of the pillow 1 to the control unit 14, which will be described later.

The control unit 20 is arranged, for example, on the lower surface of the pillow 1. However, the control unit 20 may be arranged at any position on the pillow 1. For example, the control unit 20 may be arranged outside the pillow 1. The control unit 20 includes a control unit 14 and the like, which will be described later.

The control unit 20 determines whether or not the user puts his / her head on the pillow 1 based on the output result of the detection unit 11. The details of this determination method by the control unit 20 will be described later. When the control unit 20 determines that the user has placed his / her head on the pillow 1, the control unit 20 drives the vibrating unit 10 to vibrate the pillow 1 (main body). Specifically, the control unit 20 outputs an electric signal to the vibrating unit 10 to vibrate the pillow 1 (main body). The detailed configuration of the control unit 20 will be described later.

The inside of the pillow 1 is filled with airbags 31 to 34. The airbag 31 is located above the vibrating portion 10. The airbag 32 is located below the vibrating portion 10. The airbag 33 is located on the crown side of the vibrating portion 10. The airbag 34 is located on the neck side of the vibrating portion 10.

The airbag 30 is made of, for example, a flexible and airtight material. The airbag 30 may be made of, for example, a synthetic resin material. The airbag 30 expands into a predetermined shape by injecting air into the airbag 30.

The inside of the pillow 1 may be filled with another member instead of the airbag 30. For example, the inside of the pillow 1 may be filled with a coil member, a pipe, cotton, foam beads, or the like.

Next, the details of the function of the pillow 1 will be described. FIG. 3 is a functional block diagram of the pillow 1 according to the first embodiment.

The pillow 1 includes a vibration unit 10 and a detection unit 11. The pillow 1 further includes a communication unit 12, a storage unit 13, and a control unit 14 as a control unit 20.

The vibrating unit 10 vibrates the airbag 30 based on the electric signal from the control unit 14. The vibrating unit 10 vibrates the pillow 1 by vibrating the airbag 30. The vibration of the pillow 1 is transmitted to the user who puts his head on the pillow 1.

The detection unit 11 detects the movement of the pillow 1 by the motion sensor. The detection unit 11 outputs the detected movement of the pillow 1 to the control unit 14.

The communication unit 12 is connected to an external device via a network. The communication unit 12 is, for example, Bluetooth (registered trademark), infrared rays, NFC (Near Field Communication), wireless LAN (Local Area Network), wired LAN, WAN (Wide Area Network), the Internet or any other communication medium, or any of these. Communication is possible by the combination of.

The storage unit 13 may be composed of a semiconductor memory, a magnetic memory, or the like. The storage unit 13 stores various information and a program for operating the control unit 14. The storage unit 13 may also function as a work memory. The storage unit 13 stores, for example, the optimum frequency of the pillow 1 determined by the process described later and the user's identification information.

The control unit 14 includes at least one processor 14A to provide control and processing power for performing various functions. The at least one processor 14A may be implemented as a single integrated circuit (IC) or as a plurality of communicably connected integrated circuit ICs and discrete circuits. At least one processor 14A can be implemented according to various known techniques.

In certain embodiments, the processor 14A comprises one or more circuits or units configured to perform one or more data calculation procedures and processes. For example, the processor 14A may be one or more processors, controllers, microprocessors, microcontrollers, application specific integrated circuits (ASICs), digital signal processing devices, programmable logic devices, field programmable gate arrays, or any combination or configuration thereof. The functions described below may be performed by including combinations or combinations of other known devices or configurations.

The control unit 14 is connected to the vibration unit 10, the detection unit 11, the communication unit 12, and the storage unit 13, and controls and manages the entire pillow 1 including each of these functional units. The control unit 14 acquires the program stored in the storage unit 13. The control unit 14 realizes various functions related to each unit of the pillow 1 by executing the acquired program.

The control unit 14 determines whether or not the user's head is placed on the pillow 1 based on the output result (detection result) of the detection unit 11. Specifically, for example, when the detection unit 11 includes a motion sensor, the control unit 14 puts the user's head on the pillow 1 when the motion sensor of the detection unit 11 detects the movement of the pillow 1. It is determined that it was done. For example, when the detection unit 11 includes a weight sensor, the control unit 14 may determine that the user's head is placed on the pillow 1 when the weight detected by the weight sensor exceeds a predetermined amount. For example, when the detection unit 11 includes the proximity sensor, the control unit 14 determines that the user's head is placed on the pillow 1 when the proximity sensor detects the presence of an object close to the pillow 1. May be good. For example, when the detection unit 11 includes the temperature sensor, the control unit 14 may determine that the user's head is placed on the pillow 1 when the temperature detected by the temperature sensor exceeds the first threshold value. good. The first threshold value may be, for example, a temperature at which it is possible to detect that the human body (head) is in contact with the pillow 1.

When the control unit 14 determines that the user's head is placed on the pillow 1, the control unit 14 drives the vibration unit 10 to vibrate the pillow 1 (main body). Specifically, the control unit 14 outputs an electric signal to the vibrating unit 10 to vibrate the pillow 1 (main body).

While the pillow 1 is vibrated, the control unit 14 determines whether or not the user has fallen asleep based on the output result of the detection unit 11. Specifically, the control unit 14 determines that the user has fallen asleep when the motion sensor of the detection unit 11 does not detect the movement of the pillow 1 for a predetermined time or longer. When the detection unit 11 is configured to include the temperature sensor, the control unit 14 may determine that the user has fallen asleep when the temperature detected by the temperature sensor is below the second threshold value. The second threshold value may be, for example, a temperature lower than the above-mentioned first threshold value. In general, humans have a lower body temperature when they fall asleep, so it is possible to determine sleep onset based on the temperature in this way.

When the control unit 14 determines that the user has fallen asleep, the control unit 14 stops the vibration unit 10 to stop the vibration of the pillow 1. The control unit 14 may stop the vibration of the pillow 1 immediately after determining that the user has fallen asleep, or may stop the vibration of the pillow 1 after a predetermined period of time has elapsed. The predetermined period may be set assuming the sleeping time of the user. In this case, the predetermined period may be, for example, about 7 hours. Alternatively, the predetermined period may be set assuming the time of the first non-rem sleep. In this case, the predetermined period may be, for example, the time immediately before the start of the first non-rem sleep, or the time until the end of the first non-rem sleep.

Here, the control unit 14 can determine the frequency of the pillow 1 (hereinafter, also referred to as “optimal frequency”) at which the user can easily fall asleep according to the user. For example, the control unit 14 can determine the optimum frequency according to each user. Specifically, the control unit 14 determines the optimum frequency of the pillow 1 based on the time from when the user puts his / her head on the pillow 1 to when he / she falls asleep (hereinafter, referred to as “sleep onset time”). Hereinafter, the process of determining the optimum frequency based on the sleep onset time will be described. Here, as the frequency of the pillow 1 that makes it easy for the user to fall asleep, for example, there is a frequency that stimulates the parasympathetic nerve to make the user sleep easily. As the frequency of the pillow 1 that makes it easy for the user to fall asleep, various frequencies such as 0.5 Hz, 1.0 Hz, 2.0 Hz, and 10 Hz can be used.

FIG. 4 is a diagram showing an example of the relationship between the sleep onset time and the frequency of the pillow 1. In FIG. 4, the horizontal axis represents the frequency of the pillow 1 and the vertical axis represents the sleep onset time of the user.

As shown by the solid line in FIG. 4, the sleep onset time has a minimum value at a predetermined frequency. In FIG. 4, when the frequency of the pillow 1 is fb [Hz], the sleep onset time becomes a minimum value of Tm [min]. When the user puts his / her head on the pillow 1, if the pillow 1 is vibrated at the frequency at which the sleep onset time takes a minimum value, the user can be in the state of being most likely to fall asleep. Therefore, the control unit 14 determines the frequency at which the user's sleep onset time takes a minimum value as the optimum frequency. In FIG. 4, the control unit 14 determines fb [Hz] as the optimum frequency.

Here, the relationship between the sleep onset time and the frequency of the pillow 1 as shown in FIG. 4 may differ depending on the user. That is, the frequency of the pillow 1 when the sleep onset time takes a minimum value may differ depending on the user.

The method of determining the optimum frequency will be further described. The control unit 14 measures the user's sleep onset time for each day while changing the frequency of the pillow 1 vibrated by the vibrating unit 10 by a predetermined algorithm for a predetermined number of days. The control unit 14 determines the frequency of the pillow 1 when the measured sleep onset time takes a minimum value as the optimum frequency. The control unit 14 can calculate (measure) the sleep onset time by subtracting the time when the user's head is determined to be placed on the pillow 1 from the time when the user determines that he / she has fallen asleep.

As the above-mentioned predetermined algorithm, the control unit 14 may execute a local search method such as a mountain climbing method. When executing the local search method, the control unit 14 may use a frequency that simulates the vibration of the train as the initial value of the frequency of the pillow 1. Alternatively, the control unit 14 may use, as the initial value of the frequency of the pillow 1, a frequency that pseudo-expresses the vibration when the mother shakes the child to put the child to sleep.

The control unit 14 may determine the frequency of the pillow 1 when the sleep onset time is close to the minimum value as the optimum frequency. That is, the optimum frequency determined based on the sleep onset time may include the frequency of the pillow 1 when the sleep onset time takes a value near the minimum value. In FIG. 4, the range near the minimum value is indicated by Δ. That is, the control unit 14 may determine the frequency within the range Δ as the optimum frequency. The range of Δ near the minimum value may be determined according to, for example, the sleep onset time of the user.

Even for the same user, the relationship between the sleep onset time and the frequency of the pillow 1 may change depending on the ambient temperature. For example, even for the same user, the frequency of the pillow 1 when the sleep onset time takes a minimum value in the case where the temperature is relatively high as in the summer and the case where the temperature is relatively low as in the winter. May be different.

Therefore, the control unit 14 may determine the optimum frequency for each ambient temperature. For example, the control unit 14 may determine the optimum frequency separately for the case where the ambient temperature is in the range higher than the predetermined temperature and the case where the ambient temperature is in the range lower than the predetermined temperature. The ambient temperature may be, for example, the indoor temperature acquired by the temperature sensor included in the pillow 1. The predetermined temperature may be, for example, 27 ° C. The predetermined temperature may be appropriately determined by the control unit 14 according to, for example, the usage environment of the pillow 1 (for example, the average temperature in the room). For example, the control unit 14 may determine the optimum frequency at predetermined temperature intervals (for example, every 5 ° C.).

Further, the control unit 14 may periodically execute the process of determining the optimum frequency. For example, the control unit 14 may execute the optimum frequency determination process every few months.

Further, the control unit 14 may determine the optimum frequency when, for example, the communication unit 12 receives an execution instruction of the determination process of the optimum frequency of the pillow 1 from the outside.

Further, after the control unit 14 determines the optimum frequency, the communication unit 12 may transmit the determined optimum frequency together with the user identification information to a predetermined server. The details of this process will be described later.

FIG. 5 is a flowchart showing an example of the process of determining the optimum frequency of the pillow 1 according to the first embodiment. The flow shown in FIG. 5 may be started, for example, periodically.

The control unit 14 determines whether or not the user's head is placed on the pillow 1 (step S10). When the control unit 14 determines that the user's head is placed on the pillow 1 (step S10: Yes), the control unit 14 proceeds to the process of step S11. On the other hand, when it is not determined that the user's head is placed on the pillow 1 (step S10: No), the control unit 14 performs the process of step S10 again.

In the process of step S11, the control unit 14 drives the vibrating unit 10 to vibrate the pillow 1 at a predetermined frequency. The predetermined frequency may be, for example, a frequency determined by a predetermined algorithm, or may be a different frequency from day to day.

In the process of step S12, the control unit 14 determines whether or not the user has fallen asleep. When the control unit 14 determines that the user has fallen asleep (step S12: Yes), the control unit 14 proceeds to the process of step S13. On the other hand, when it is not determined that the user has fallen asleep (step S12: No), the control unit 14 performs the process of step S12 again.

In the process of step S13, the control unit 14 stops the vibration unit 10 to stop the vibration of the pillow 1.

In the process of step S14, the control unit 14 measures the sleep onset time. For example, the control unit 14 subtracts the time when the user's head is determined to be placed on the pillow 1 in the process of step S10 from the time when the user is determined to have fallen asleep in the process of step S12, thereby determining the sleep onset time. Calculate (measure).

In the process of step S15, the control unit 14 determines whether or not a predetermined number of days have elapsed since the process of the flow shown in FIG. 5 was started. When the control unit 14 determines that the predetermined number of days has elapsed (step S15: Yes), the control unit 14 proceeds to the process of step S16. On the other hand, when it is not determined that the predetermined number of days has passed (step S15: No), the control unit 14 repeats the process from step S10. In this case, the control unit 14 starts the process from step S10 again after determining that the user's head is separated from the pillow 1. That is, the control unit 14 can start the process from step S10 when the user wakes up once and then sleeps again using the pillow 1.

In the process of step S16, the control unit 14 determines the optimum frequency based on the sleep onset time measured while changing the frequency of the vibration unit 10 by a predetermined algorithm for a predetermined number of days.

When the control unit 14 acquires the amount of data necessary for determining the optimum frequency, the control unit 14 may proceed to the process of step S16 even before the predetermined number of days has elapsed.

Further, when determining the optimum frequency for each ambient temperature, the control unit 14 may acquire the ambient temperature and execute the flow shown in FIG. 5 for each acquired ambient temperature.

FIG. 6 is a flowchart showing an example of the sleep induction process of the pillow 1 according to the first embodiment. The flow shown in FIG. 6 is executed when the optimum frequency is determined by, for example, the flow shown in FIG. The flow shown in FIG. 6 may be started at a predetermined time, for example. The predetermined time may be set based on the time when the user goes to bed.

The control unit 14 determines whether or not the user's head is placed on the pillow 1 (step S20). When the control unit 14 determines that the user's head is placed on the pillow 1 (step S20: Yes), the control unit 14 proceeds to the process of step S21. On the other hand, when it is not determined that the user's head is placed on the pillow 1 (step S20: No), the control unit 14 performs the process of step S20 again.

In the process of step S21, the control unit 14 drives the vibrating unit 10 to vibrate the pillow 1 at the optimum frequency.

In the process of step S22, the control unit 14 determines whether or not the user has fallen asleep. When the control unit 14 determines that the user has fallen asleep (step S22: Yes), the control unit 14 proceeds to the process of step S23. On the other hand, when it is not determined that the user has fallen asleep (step S22: No), the control unit 14 performs the process of step S22 again.

In the process of step S23, the control unit 14 stops the vibration unit 10 to stop the vibration of the pillow 1.

When the optimum frequency is determined for each ambient temperature, the control unit 14 may acquire the ambient temperature and vibrate the pillow 1 at the optimum frequency corresponding to the acquired ambient temperature in the process of step S21.

Here, as a comparative example, an example in which the pillow 1 is vibrated at a fixed frequency is assumed. As described above, the relationship between the sleep onset time and the frequency of the pillow 1 may differ depending on the user. Therefore, even if the pillow 1 is vibrated at a fixed frequency, the user is not always encouraged to fall asleep. Further, if the pillow 1 is vibrated at a fixed frequency, it may be possible to encourage some users to fall asleep, but it may be difficult to encourage other users to fall asleep.

On the other hand, the pillow 1 according to the present embodiment determines the optimum frequency of the pillow 1 based on the sleep onset time of the user. By such control, the pillow 1 can vibrate at an optimum frequency according to the user. Thereby, the pillow 1 according to the present embodiment can further promote the user to fall asleep. Therefore, according to this embodiment, an improved pillow 1 can be provided.

Further, even for the same user, the relationship between the sleep onset time and the frequency of the pillow 1 may change depending on the ambient temperature. Even in such a case, the pillow 1 according to the present embodiment can determine the optimum frequency of the pillow 1 according to the ambient temperature. Thereby, the pillow 1 according to the present embodiment can promote the user to fall asleep even if the relationship between the user's sleep onset time and the frequency of the pillow 1 changes.

Further, the network 200 may be wireless, wired or a combination thereof. That is, the pillow 1 and the pillow 1A and the server 2 may be connected by a network 200 configured by wired or wireless or any combination thereof to transmit and receive information. Further, in the present embodiment, the server 2 and the network 200 are not limited to one, and may be two or more each.

That is, the pillow 1A includes a vibration unit, a detection unit, a communication unit, a storage unit, and a control unit as shown in FIG. Pillow 1A is used by any user in a public place such as an accommodation facility or a hospital. Hereinafter, the pillow 1A shall be used by an unspecified user (guest) at the accommodation facility.

The pillow 1A acquires the identification information of the user (guest) who uses the pillow 1A from the outside, for example, via the communication unit of the pillow 1A. For example, when the staff of the accommodation facility operates a computer, the identification information of the user (guest) who uses the pillow 1A is transmitted from the computer to the pillow 1A. When the pillow 1A acquires the user's identification information, the pillow 1A transmits a signal requesting the optimum frequency together with the user's identification information to the server 2 via the network 200. After that, the optimum frequency is transmitted from the server 2 to the pillow 1A. Pillow 1A acquires the optimum frequency from the server 2 via the network 200.

When the user (guest) determines that the head is placed on the pillow 1A, the pillow 1A vibrates at the acquired optimum frequency.

The server 2 is, for example, an information processing device. The server 2 includes a communication unit 40, a storage unit 41, and a control unit 43.

The communication unit 40 communicates with an external device via the network 200. The communication unit 12 can communicate by, for example, Bluetooth (registered trademark), infrared rays, NFC, wireless LAN, wired LAN, WAN, the Internet or any other communication medium, or any combination thereof.

The storage unit 41 may be composed of a semiconductor memory, a magnetic memory, or the like. The storage unit 41 stores various information and a program for operating the control unit 42. The storage unit 41 may also function as a work memory. The storage unit 41 stores the optimum frequency in association with the user's identification information.

The control unit 42 includes at least one processor 42A in order to provide control and processing power for performing various functions. The at least one processor 42A may be implemented as a single integrated circuit (IC) or as a plurality of communicable integrated circuit ICs and discrete circuits.

For example, the processor 42A may be one or more processors, controllers, microprocessors, microcontrollers, application specific integrated circuits (ASICs), digital signal processing devices, programmable logic devices, field programmable gate arrays, or any combination or configuration thereof. The functions described below may be performed by including combinations or combinations of other known devices or configurations.

The control unit 42 is connected to the communication unit 40 and the storage unit 41, and controls and manages the entire server 2 including each of these functional units. The control unit 42 acquires the program stored in the storage unit 41. The control unit 42 realizes various functions related to each unit of the server 2 by executing the acquired program.

The control unit 42 receives the optimum frequency from the pillow 1 via the network 200 together with the identification information of the user of the pillow 1 by the communication unit 40. When the control unit 42 receives the optimum frequency or the like, the control unit 42 stores the optimum frequency in the storage unit 41 in association with the identification information of the user of the pillow 1.

The control unit 42 receives from the pillow 1A via the network 200 a signal requesting the optimum frequency together with the identification information of the user (guest) by the communication unit 40. Upon receiving this request, the control unit 42 acquires the optimum frequency associated with the user's identification information from the storage unit 41. The server 2 transmits the optimum frequency to the pillow 1A via the network 200 by the communication unit 40.

FIG. 8 is a sequence diagram showing an example of the control procedure of the communication system 100 according to the second embodiment.

The pillow 1 determines the optimum frequency according to the user of the pillow 1 (step S30). After the process of determining the optimum frequency is completed, the pillow 1 transmits the optimum frequency together with the identification information of the user of the pillow 1 to the server 2 via the network 200 (step S31).

The server 2 receives the optimum frequency from the pillow 1 via the network 200 together with the identification information of the user of the pillow 1. The server 2 stores the optimum frequency in the storage unit 41 in association with the user identification information of the pillow 1 (step S32).
