Description

[Technical field]

[0001] The present invention relates to a non-contact vital data monitor system capable of acquiring the position and vital data of a subject in a non-contact manner. [Background technology]

[0002] Conventionally, home appliances such as surveillance cameras and pots and robots equipped with monitoring functions have been put to practical use in monitoring the health condition of individuals in living spaces such as homes and elderly care facilities, and identifying their location in real time. It has been difficult to protect the privacy of subjects of images and audio data captured by surveillance cameras and robots. Even if the captured images are real-time images, there are cases where the health condition of the subject cannot be immediately determined, such as during sleep during the day or night. The home appliances equipped with the monitoring function described above wait for operation input from the subject, and cannot constantly monitor the subject's health condition.

[0003] The following technologies have already been developed to solve these problems: For example, Patent Document 1 (JP Patent Publication No. 2018-524129) discloses a remote monitoring system for human activities. The system is a system for remotely monitoring at least one object in a predefined space, and includes a sonar module and a radar module coupled to each other to simultaneously acquire data related to the at least one object, and at least one processing subsystem configured to perform at least one of controlling the sonar module and the radar module, processing the data, and communicating information and instructions with an external device.

[0004] Also, Patent Document 2 (JP Patent Publication 2023-521416 A) discloses a non-contact sensor-driven device, system, and method for enabling environmental health monitoring and predictive assessment. The device is an environmental monitoring device that includes a housing, a plurality of non-contact sensors coupled to the housing, and a processing device disposed in the housing and coupled to the plurality of non-contact sensors, the processing device receiving historical sensor data from one or more non-contact sensors of the plurality of non-contact sensors, determining a baseline vital sign based on the historical sensor data, receiving current sensor data from the one or more non-contact sensors related to a user who is within a threshold distance of the environmental monitoring device without contacting the environmental monitoring device, determining a current vital sign of the user based on the current sensor data, and providing an alert in response to a determination that the current vital sign does not meet the baseline vital sign.

[0005] [Patent Document 1] Special Publication No. 2018-524129 [Patent Document 2] Special Publication No. 2023-521416 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the remote monitoring system of Patent Document 1 and the system of Patent Document 2 both acquire vital data of one subject, and are not capable of acquiring, accumulating, and processing the individual vital data of multiple subjects in real time, and simultaneously monitoring the vital data of multiple subjects. In addition, it is difficult to identify the location of the subject while protecting the privacy of the subject.

[0007] In view of the above-described situation, the present invention aims to provide a non-contact vital sign monitoring system that can monitor a subject's vital signs in a non-contact manner without having to be equipped with a surveillance camera, audio sensor, or the like, and can also identify the subject's location while protecting the subject's privacy.

[0008] The present invention aims to provide a non-contact vital data monitoring system that can individually acquire, accumulate, and process vital data of multiple subjects, monitor the vital data of multiple subjects simultaneously, and identify the positions of the subjects in real time along with the vital data. [Means for solving the problem]

[0009] The present invention provides a non-contact vital data monitoring system that acquires and monitors vital data of a subject, comprising a vital sensor that is arranged within the subject's presence space facing the subject's presence area, and a vital data monitoring device that acquires vital data from the vital sensor and has a vital data recording unit that retains the acquired vital data, wherein the vital data can include at least one of the subject's position and horizontal movement speed, and at least one of the subject's pulse rate, blood pressure, respiratory rate, and body temperature.

[0010] The subject may be, for example, an elderly person, a patient, an infant, or other person who requires monitoring of their vital signs, or may be a person who does not require monitoring of their vital signs. The subject may be, for example, a non-human animal, such as a pet or livestock.

[0011] The subject's presence space is, for example, a space where a person lives or stays. The presence space is, for example, a home where the subject is present, a nursing home, a hospital facility, an accommodation facility, or other space where a certain degree of privacy is ensured (to a certain extent that caregivers, visitors, etc. enter and leave on a daily basis). The subject's presence area is, for example, an area within the subject's presence space, particularly an area where the subject is frequently present on a daily basis. The subject's presence area can be, for example, a seat, table, bed, bathroom, toilet, hallway, or other area where the subject is mainly or frequently present.

[0012] The vital sensor acquires vital data of the subject. The vital sensor is disposed in the subject's presence space facing the subject's presence area. The vital data may include, for example, at least one of the subject's position information and horizontal movement speed, and at least one of the subject's pulse rate, blood pressure, respiratory rate, and body temperature. The vital data may further include detection of the presence or absence of the subject, detection of the subject's sitting or lying position, blood pressure, body temperature, etc.

[0013] The vital sensor is preferably a 60 GHz millimeter wave radar. The 60 GHz radar has a wider bandwidth than other frequency bands, and can use the FMCW (frequency-continuously modulated wave) method to simultaneously detect breathing and pulse rate and the subject's position (XY coordinate position) from the frequency shift of the reflected signal without contact. In this regard, the 24 GHz radar has a narrow bandwidth, and can detect breathing and pulse rate without contact from the frequency change caused by the Doppler effect of radio waves reflected from a moving object using a fixed frequency, but the coordinate error of the subject's position (XY coordinate position) is large, making it difficult to identify the subject. In other words, by using a vital sensor that outputs a 60 GHz millimeter wave radar, breathing and pulse rate and the subject's position (XY coordinate position) can be measured simultaneously.

[0014] The vital sensor can be equipped with a subject identification unit that, for example, constantly monitors the subject's vital signs, and when a caregiver or the like appears in the presence area from outside, compares the history of the vital signs with the real-time vital signs, determines the continuity of the vital signs, identifies the subject, and continues acquiring the vital signs.

[0015] The vital sensor may include, for example, a caregiver identification unit that identifies the caregiver from the caregiver's non-contact IC or the like, and a visitor information addition unit that suspends acquisition of vital data when the caregiver appears in the presence area from the outside during monitoring, monitors the stop time as the caregiver's stay time, sets the caregiver's stay time as stay time information, and adds the ID information of the caregiver identified by the caregiver identification unit and the stay time information of the caregiver to the vital data and transmits it. The visitor information addition unit may, for example, compare the history of the vital data of the subject with the real-time vital data while the caregiver is staying in the presence area, determine the continuity of the vitals, and continue acquiring the vital data of the subject. Also, unique identification information may be set for each vital sensor installed in the presence space of the subject.

[0016] The vital data monitoring device acquires vital data from the vital sensor. The vital data monitoring device may be, for example, a server, a PC terminal, a mobile terminal, a smartphone, an IC, a microcomputer, or the like. The vital data monitoring device may be, for example, integrated with or separate from a vital sensor. The vital data monitoring device may have, for example, a vital data recording unit that holds the acquired vital data. The vital data monitoring device may be, for example, integrated with or separate from the vital sensor. The vital data recording unit may be, for example, integrated with or separate from the vital data monitoring device. The vital data recording unit may be, for example, various memories, databases, cloud services, or the like.

[0017] The present invention relates to a non-contact vital monitoring system in which the vital sensor is equipped with a reference value recording unit that records normal or abnormal values ​​of the vital sensor, and is also equipped with an abnormality notification unit that constantly monitors the acquired vital data based on the values ​​of the reference value recording unit and, upon detecting an abnormal value, transmits in real time to the vital data monitoring device that an abnormality has occurred.

[0018] The reference value recording unit of the vital sensor records normal or abnormal values ​​of the vital sensor, and constantly monitors the vital data based on the values ​​of the reference value recording unit. The normal values ​​of the vital data can be, for example, any of the following ranges: respiration: 14 to 20 times / min, body temperature: 36.0 to 36.9°C, blood pressure: systolic less than 120 mmHg, diastolic less than 80 mmHg, pulse: 50 to 80 times / min. The abnormal value of the vital data can be, for example, any value outside the normal ranges of respiration, body temperature, blood pressure, and pulse.

[0019] The abnormality notification unit of the vital sensor transmits in real time to the vital data monitoring device a notification that an abnormality has occurred when the reference value recording unit detects an abnormal value of the vital data.

[0020] The present invention relates to a non-contact vital monitor system in which the vital data monitoring device is provided with a reference value recording unit that records the acceptable range or abnormal range of the acquired vital data, and is also provided with a vital data monitoring unit that compares the acquired vital data with the values ​​in the reference value recording unit and issues an alarm or warning if the value is abnormal.

[0021] The reference value recording unit of the vital data monitoring device records the allowable range or abnormal range of the vital data. The allowable range of the vital data can be, for example, any of the following: respiration: 14 to 20 times / min, body temperature: 36.0 to 36.9°C, blood pressure: systolic less than 120 mmHg, diastolic less than 80 mmHg, pulse: 50 to 80 times / min. The abnormal range of the vital data can be, for example, a range in which at least one of the respiration, body temperature, blood pressure, and pulse is outside of the normal range.

[0022] The present invention relates to a non-contact vital monitor system, in which the vital data monitoring device includes a state determination unit for determining whether a subject is away from the room, present in the room, resting, or has an abnormality based on the acquired vital data.

[0023] The subject's state determination unit of the vital data monitoring device determines whether the subject has left the room, is present, is at rest, or is abnormal. The state determination unit, for example, determines that the subject is present while detecting the subject's vital data (at least one of the subject's position and horizontal movement speed, and at least one of the subject's pulse rate, blood pressure value, respiratory rate, and body temperature). The state determination unit, for example, determines that the subject is present when the subject is running or moving quickly in the room based on the subject's position (XY coordinate position) and horizontal movement speed. The state determination unit, for example, determines that the subject has left the room when a person cannot be detected in the room because vital data cannot be acquired. It can also determine whether the subject is at rest or abnormal based on at least one of the subject's vital data, namely, the subject's pulse rate, blood pressure value, respiratory rate, and body temperature.

[0024] The status determination unit can, for example, determine that the subject has left the room as normal if it becomes impossible to obtain vital data of the subject, and the vital data for the immediately preceding few seconds is within a normal range, and immediately thereafter, the subject's position information cannot be obtained; and determine that the subject has left the room as abnormal (abnormal), such as collapsing, if at least any of the vital data for the immediately preceding few seconds, namely pulse rate, blood pressure, respiratory rate, and body temperature, is within an abnormal range, and immediately thereafter, at least any of the vital data, namely the subject's position information and horizontal movement speed, cannot be obtained.

[0025] When the state determination unit determines that the acquired vital data is within a normal and resting range, it estimates that the subject is stationary or walking slowly indoors and determines that the subject is resting. When at least one of the acquired vital data of pulse rate, blood pressure value, respiratory rate, and body temperature is outside the normal range, the state determination unit determines that the subject is abnormal. The state determination unit can estimate the moving state of the subject based on at least one of position information and horizontal movement speed, and can further record in the reference value recording unit the normal range of the subject's heart rate and respiratory rate when the subject is moving quickly and the normal range of the heart rate and respiratory rate when the subject is moving slowly based on the acquired vital data as the inherent normal range of the subject's vitals, and can determine whether the subject is normal or abnormal based on the inherent normal range of the subject's vitals.

[0026] The resting range of the vital data can be, for example, the allowable range or abnormal range of the vital data. The state determination unit can set the allowable range of the vital data for determining the resting state of the subject and the abnormal range for determining the abnormality to be wider, narrower, higher, lower, etc. for each subject. For example, if the subject exercises indoors on a daily basis, or if the subject has a narrow allowable range due to a chronic illness, the activity time period for each subject, such as daytime or nighttime, can be set according to the circumstances of each person. Furthermore, the allowable range of the vital data can be set to be wider, narrower, higher, lower, etc. according to the amount of exercise of each person.

[0027] The present invention relates to a non-contact vital monitor system in which the vital sensor transmits identification information for identifying each vital sensor along with the vital data to the vital data monitoring device, and a vital data recording unit of the vital data monitoring device records the vital data for each of the identification information.

[0028] The vital sensors transmit individual identification information to the vital data monitoring device in conjunction with the transmission of the vital data. Even when a plurality of vital sensors are installed, for example, the vital data monitoring device can identify each vital sensor and manage the vital data of each. For example, even when a plurality of vital sensors are installed (for each subject) facing a plurality of existence areas in the existence space of each of a plurality of subjects, since identification information is set for each vital sensor, the vital data of each subject can be managed simultaneously. Effect of the Invention

[0029] According to the non-contact vital monitor system of the present invention, the vital signs of a subject can be monitored without contact. This has the excellent effect of protecting the privacy of the subject. In particular, the vital data acquired by the vital sensor includes at least one of the subject's position information and horizontal movement speed, and at least one of the subject's pulse rate, blood pressure value, respiratory rate, and body temperature, so that the subject's real-time position can be identified and at least one of the vital data of the pulse rate, blood pressure value, respiratory rate, and body temperature can be acquired simultaneously.

[0030] The vital sensor constantly monitors the subject's vital signs, and when it detects an abnormality in the vital data, it can transmit the occurrence of the abnormality to the vital data monitoring device in real time.

[0031] The vital data monitoring device constantly monitors the vital data from the vital sensor, and when an abnormality is detected in the vital data, it can notify the occurrence of the abnormality in real time.

[0032] The vital data monitoring device determines whether the patient has left the room, is present, is at rest, or has an abnormality based on the vital data, enabling more accurate monitoring.

[0033] Since the vital sensor transmits identification information to the vital data monitoring device, the vital data monitoring device can identify a plurality of vital sensors and record the individual vital data for each identification information. The vital data of a plurality of subjects can be managed simultaneously in real time. [Brief description of the drawings]

[Figure 6] FIG. 2 is a system configuration diagram of the mobile data monitoring device 3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] Hereinafter, the non-contact vital sign monitor system according to the present embodiment will be specifically described with reference to the drawings. In particular, the present embodiment is for monitoring each subject 4 in real time in a nursing home, hospital, or the like, where there are multiple rooms 40 in which one elderly person (subject) 4 resides.

[0036] As shown in FIGS. 1 to 6, the non-contact vital sign monitor system 1 includes a vital sign sensor 2 and a vital sign data monitoring device 3. The vital sign sensor 2 and the vital sign data monitoring device 3 include a vital sign sensor 2 and a vital sign data monitoring device 3. The vital sensor 2 is installed in a room 40 as the subject's 4 presence space. The vital sensor 2 is arranged, for example, facing the subject's 4 chair, bed, etc., which is the subject's presence area 41. The vital sensor 2 includes, for example, a 60 Hz band millimeter wave radar 20. Specific specifications are, for example, as shown in Table 1 below. As a result, the real-time position of the subject can be identified at the same time as at least one of vital data of pulse rate, blood pressure value, respiratory rate, and body temperature. The vital data acquired by the vital sensor 2 includes, for example, the horizontal movement speed (X and Y directions), heart rate, respiratory rate, etc. of the subject 4.

[0037] [Table 1]

[0038] The vital data monitoring device 3 includes, for example, a server 30 equipped with a vital data monitoring unit 30a that acquires vital data from the vital sensor 2, and a database 31 as a vital data recording unit 31b that holds the vital data acquired by the server 30, or a cloud service 31a on the Internet. The vital data monitoring device 3 includes, for example, a server 30, a database 31 (and / or a cloud service 31a on the Internet), a terminal device 32, and the like, as shown in Figs. 1(A) and (B). As shown in Fig. 1(B), the server 30 (or a PC terminal 30 that performs the function thereof) and the PC terminal 32 connected to the server 30, and the like, can be installed in a private room 5 or a management room 5 that can protect the privacy of the subject 4.

[0039] The communication between the vital sensor 2 and the server 30 of the vital data monitoring device 3 is performed by wired or wireless means. The communication is performed, for example, by wireless LAN or Bluetooth (registered trademark) via a router or the like, as shown in Fig. 4. For example, the server 30 can be replaced by a terminal device 32 that performs the function thereof, such as a PC terminal 32.

[0040] The vital sensor 2 includes, for example, a reference value recording unit 21 that records normal or abnormal values ​​of the vital sensor 2, and an abnormality notification unit 22 that constantly monitors the acquired vital data based on the values ​​of the reference value recording unit 21 and transmits in real time to the server 30 of the vital data monitoring device 3 a notification that an abnormality has occurred when an abnormal value is detected.

[0041] The vital sensor 2 transmits the vital data recorded in the reference value recording unit 21 in real time, for example, once every few seconds to several minutes. The vital sensor 2 has, for example, a security unit 23 that applies security before transmitting the vital data. The vital sensor 2 has, for example, an identification information unit 24 that adds identification information for identifying each vital sensor 2 together with the vital data.

[0042] The server 30 includes, for example, a reference value recording unit 30b that records an allowable range or an abnormal range of the acquired vital data. The server 30 includes, for example, an alarm unit that compares the acquired vital data with the value of the reference value recording unit 30b and issues an alarm or warning such as displaying an image, generating a sound, turning on a rotating light, emitting a flash, or sending an alarm to a mobile terminal if the value is abnormal.

[0043] The server 30 includes a state determination unit 30c for determining whether the subject 4 is away from the room, present, resting, or abnormal based on the acquired vital data. The reference values ​​of the vital data for determining whether the subject 4 is away from the room, present, resting, or abnormal can be set to values ​​corresponding to the states shown below. The reference value recording unit 30b and the state determination unit 30c can be provided in, for example, the server 30, a database 31 capable of fulfilling the functions of the server 30, a cloud service 31a on the Internet, or a terminal device 32.

[0044] [Table 2]

[0045] The judgment criteria of the state judgment unit 30c are, for example, resting when the heart rate is within the range of 50 to 80 beats / min and the respiratory rate is within the range of 14 to 20 beats / min, abnormal when the heart rate is outside the range of 50 to 80 beats / min and the respiratory rate is outside the range of 14 to 20 beats / min, being in the room when the horizontal movement speed (X, Y directions) is within the range of 0.8 to 1.0 m / sec, and leaving the room when the subject 4 is not detected.

[0046] The vital sensor 2 transmits identification information identifying each vital sensor to the server 30 of the vital data monitoring device 3 along with the vital data, and the server 30, upon receiving this signal, records the vital data of each subject linked to each identification information (vital sensor 2) in the vital data recording section 31b of the database 31.

[0047] The vital sensor 2 is controlled according to, for example, the flow diagram of FIG. 2. When the non-contact vital monitor system 1 (vital sensor 2, vital data monitoring device 3) is started (a), the vital sensor 2 constantly acquires vital data of the subject 4 (b). The normal values ​​of the vital sensor recorded in the reference value recording unit 21 are, for example, any of the following values: horizontal movement speed (X, Y directions) 0.8 to 1.0 m / sec, heart rate: 50 to 80 beats / min, and respiratory rate: 14 to 20 beats / min. The abnormal values ​​are, for example, any of the following values: horizontal movement speed (X, Y directions) less than 0.8 and more than 1.0 m / sec, heart rate: less than 50 beats / min and more than 80 beats / min, and respiratory rate: less than 14 beats / min and more than 20 beats / min. The abnormality notification unit 22 determines (c) whether there is an abnormality in the vital signs based on the normal value or abnormal value.

[0048] The abnormality notification unit 22 constantly monitors based on the normal or abnormal value of the vital sensor recorded in the reference value recording unit 21, and when the abnormal value is detected (YES), transmits in real time (d) a notification that an abnormality has occurred (an alert) to the server 30 of the vital data monitoring device 3. The server 30 that receives the alert may, for example, display an alert image on the screen of the terminal device 32 and output an alert sound.

[0049] When the abnormality notification unit 22 does not detect the abnormal value (NO), the identification information unit 24 adds identification information of each vital sensor 2 to the vital data from each vital sensor 2. At least one piece of identification information (ID) is assigned to each vital sensor 2. Furthermore, the security unit 23 applies security to the vital data (to which the identification information has been added) before transmission (e).

[0050] The vital sensor 2 transmits secured vital data once every few seconds to several minutes (f). The plurality of vital sensors 2 are capable of network communication in infrastructure mode or ad-hoc mode with the vital data monitoring device 3. The vital sensor 2 determines (g) whether or not it has been stopped, and if it has not been stopped (NO), it continues acquiring vital data (b). If it has been stopped (YES), it stops the system (h).

[0051] The database 31 of the vital data monitoring device 3 has, for example, a vital data recording unit 31b that records vital data of the multiple subjects 4, and a personal information recording unit 31c that records personal information of the multiple subjects 4. The vital data recording unit 31b receives and accumulates the vital data of the multiple subjects 4, each of which is assigned identification information, via the server 30. The accumulated vital data is linked to the personal information of each subject 4, with each identification information being linked. The personal information is, for example, "name (room number) of each subject 4," "name," "gender," "age," "care level," "person in charge 1," "person in charge 2," "remarks," etc.

[0052] The server 30 can display a monitoring image 32d shown in FIG. 4 on a PC such as a desktop, laptop, or tablet or other terminal device 32. In this monitoring image 32d, for example, a plurality of icons 32e simulating rooms 4 for each of a plurality of subjects 4 shown in FIG. 1(B) and FIG. 3 are displayed. The server 30 has an icon arrangement unit that displays each icon 32e in order of room number, name of the subject 4, or the like. The server 30 can have an icon arrangement unit that can change the display position of each icon 32e by mouse operation or the like so as to match the arrangement of each room 40 in an actual building or to arrange the icon 32 of the room 40 that needs to be monitored in a position that is easy to see, and can fix (and release) the icon 32e so that it does not move carelessly. The server 30 can have an icon arrangement unit that grasps the distance and direction of each vital sensor 2 by wireless communication and aligns and displays the icon 32e of each room 40 on the monitoring image 32d in accordance with the grasped arrangement.

[0053] The icon 32e displays the name of each room (room number) and the name of each subject 4. The icon 32e displays the judgment results of the state judgment unit 30, "Away" 6a, "Present" 6b, "Rest" 6c, and "Abnormal" 6d, in white on a different background color, and a pictogram representing each state. The background color of the icon 32e is, for example, matcha green for "Away" 6a, light blue for "Present" 6b, light green for "Rest" 6c, and cherry blossom green for "Abnormal" 6d. The icon 32e displays the heart rate and respiratory rate of each subject 4. When the icon 32e indicates "Abnormal" 6d, the corresponding icon 32e is displayed flashing, and a sound notifying the abnormality can be emitted through the speaker of the terminal device 32.

[0054] For example, when any icon 32e of the monitoring image 32d is selected, a detailed screen 32f can be displayed that displays a graph of real-time vital data (heart rate, respiratory rate) and the history of vital data (heart rate, respiratory rate) associated with the selected icon 32e. The detailed screen 32f displays, for example, the same background color as the icon 32e, the room name (room number), the name of the subject 4, and a pictogram indicating the determination result of the state determination unit 30. The server 30 has, for example, a subject position display unit. The subject position display unit displays, for example, where the subject 4 is in the room with an illustration or a mark such as a circle or a star on the detailed screen 32f, and displays a subject position display window 7 that updates and displays the position coordinates in real time if the subject 4 is active.

[0055] The mobile data monitoring device 3 may be configured, for example, as shown in the system configuration diagram of FIG. 6, in which a CPU 300, a memory 300b, a display controller 32a, an input device 32b, an external storage device 310, a communication interface 34, an external storage medium slot 34a, etc. are connected via a bus 35.

[0056] The CPU 300 controls the mobile data monitoring device 3. The CPU 300 is provided, for example, in the server 30 (or a PC terminal 32 that performs the function thereof). The CPU 300 is driven, for example, based on software stored in the memory 300b, and serves as the vital data monitoring unit 30a and the state determination unit 30c.

[0057] The memory 300b functions as at least a ROM or RAM of the CPU 300, for example, and is used for at least controlling the mobile data monitoring device 3 or executing software. The memory 300b has, for example, the reference value recording unit 30b. The audio output device 32c receives a command from the CPU 300 and, for example, issues the alert sound. For example, it is a speaker connected to or provided on the server 30 or the PC terminal 32. The audio output device 32c can have, for example, lamps such as rotating lights or strobe lights, and can emit light along with the sound. The audio output device 32c can be replaced with, for example, the lamps.

[0058] The display controller 32a is connected to a display 33. The display controller 32a receives an image signal from the CPU 300 and controls the image display on the display 33. The display controller 32a can be, for example, a graphic board.

[0059] The display 33 displays images under the control of the display controller 32a. The input device (interface) 32b enables an administrator of the mobile data monitoring device 3 to input data to the server 30 or the PC terminal 32. The input device 32b can be, for example, a keyboard, a mouse, a touch panel, or the like.

[0060] The external storage device 310 is a storage device provided outside the memory 300b. The external storage device 310 can be, for example, the database 31. The external storage device 310 has, for example, the vital data recording unit 31b and the personal information recording unit 31c.

[0061] The communication interface 34 enables communication of the CPU 300. The communication interface 34 can be connected to, for example, the cloud service 31a on the Internet. The communication interface 34 can be connected to, for example, the vital sensor 2. The communication interface 34 can communicate, for example, by wire, wireless, LAN standard, Bluetooth, optical line, and various other communication standards.
