Description

[Technical field]

[0001] The present invention relates to an information monitoring device that monitors measured information, an information management system that uses the information monitoring device, an immigration inspection method, an admission management method, and an information management program. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been known a system in which a temperature sensor is attached to the human body with an adhesive patch, and the temperature is measured and accumulated (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2009-535141 Summary of the Invention [Problem to be solved by the invention]

[0004] However, according to the technology described in Patent Document 1, the user can freely remove or reattach the temperature sensor, so even if a third party tries to check the measured body temperature at a later date, it is not necessarily the case that body temperatures measured continuously for a certain period of time have been accumulated.

[0005] An object of the present invention is to provide an information monitoring device, an information management system, an immigration inspection method, an admission management method, and an information management program that make it easy to confirm that detected information is information that is detected continuously. [Means for solving the problem]

[0006] The information monitoring device of the present invention is an information monitoring device for monitoring information, and comprises a sensor that detects specified target information from a measurement object, a detection control unit that controls the sensor to repeatedly detect the target information, a holding member for attaching and holding the sensor to the measurement object, and a detachment detection unit that detects when the sensor is detached from the measurement object.

[0007] According to this configuration, it is possible to repeatedly detect the target information from the measurement object. Furthermore, when the sensor is removed from the measurement object, the removal can be detected, so it is easy to confirm that the detected information is the information that is detected continuously.

[0008] It is also preferable that the removal detection unit includes an optical sensor that is shielded from light in the surrounding environment when the sensor is attached to the object to be measured, and that can receive light from the surrounding environment when the sensor is detached from the object to be measured.

[0009] According to this configuration, when the sensor is removed from the object to be measured, light from the surrounding environment is received by the optical sensor, and the optical sensor detects the light from the surrounding environment, thereby making it possible to detect that the sensor has been removed from the object to be measured.

[0010] It is also preferable that the information monitoring device further includes a release sheet removably attached to a mounting surface that is intended to be attached to the measurement object, the release sheet shielding the optical sensor from the surrounding environment when attached to the mounting surface, and the detachment detection unit further includes a detachment determination unit that determines that the sensor has been detached from the measurement object when a specified light is detected by the optical sensor, the specified light is no longer detected by the optical sensor, and then the specified light is detected again by the optical sensor.

[0011] According to this configuration, before the information monitoring device is attached to the measurement object, a release sheet is attached to the attachment surface to shield the optical sensor from light in the surrounding environment. Then, when the release sheet is peeled off to attach the information monitoring device to the measurement object, the light in the surrounding environment is detected by the optical sensor. When the information monitoring device is then attached to the measurement object, the optical sensor is shielded from light in the surrounding environment and the optical sensor no longer detects light. When the sensor is then removed from the measurement object, the light in the surrounding environment is detected by the optical sensor, and the light is detected by the optical sensor. Therefore, the removal determination unit can determine that the sensor has been removed from the measurement object when the optical sensor detects a predetermined light, then stops detecting the predetermined light, and then detects the predetermined light again.

[0012] The information monitoring device further comprises a release sheet removably attached to a mounting surface of the information monitoring device that is intended to be attached to the measurement object, a battery that supplies power to operate the information monitoring device, and a power control unit that starts supplying power from the battery when a specified light is detected by the optical sensor, and it is preferable that the release sheet, when attached to the mounting surface, shields the optical sensor from the surrounding environment.

[0013] According to this configuration, when a user peels off the release sheet to start using the information monitoring device, the light in the surrounding environment is detected by the light sensor and power supply from the battery begins. This makes it possible to cut off the power supply from the battery until the release sheet is peeled off from the information monitoring device, thereby reducing the risk of the battery becoming depleted while the information monitoring device is stored and not being used.

[0014] It is also preferable that the electronic device further includes a start-up control unit that starts the control by the detection control unit when the optical sensor detects a predetermined light and then stops detecting the predetermined light.

[0015] According to this configuration, the target information is acquired after the release sheet is peeled off and a specified light is detected by the optical sensor, and then the information monitoring device is attached to the measurement object so that the sensor can detect the target information, thereby reducing the risk of the environmental temperature, etc., being mistakenly detected as target information before the information monitoring device is attached to the measurement object.

[0016] It is also preferable that the detachment detection unit detects that the sensor has been detached from the measurement object based on the objective information detected by the sensor.

[0017] According to this configuration, when the sensor is detached from the measurement object, the sensor is no longer able to detect the object information from the measurement object, and therefore the detachment detection unit is able to detect that the sensor has been detached from the measurement object based on the object information detected by the sensor.

[0018] The holding member is preferably a sheet member having an adhesive layer that adheres to the measurement object.

[0019] According to this configuration, the information monitoring device can be attached to the measurement target by the adhesive layer.

[0020] In addition, the detachment detection unit may include a member that is provided on at least a part of the sheet member and that, when peeled off after being attached to the object to be measured, detects that the sensor has been detached from the object to be measured by generating a predetermined pattern or changing color.

[0021] According to this configuration, when the information monitoring device is peeled off after being attached to the measurement object, at least a part of the sheet member develops a predetermined pattern or changes color, so that it is visually known that the sensor has been removed from the measurement object, and therefore it is possible to detect that the sensor has been removed from the measurement object.

[0022] The sheet member is preferably a ticket.

[0023] According to this configuration, the information monitoring device can be used as a ticket.

[0024] It is also preferable that the detection control unit shortens an interval between detections by the sensor when the objective information corresponds to a preset specific event.

[0025] By shortening the detection interval, the detection frequency of the target information is increased. This reduces the detection frequency of the target information, thereby reducing power consumption and processing load, while increasing the detection frequency of the target information when the need is high, thereby improving the monitoring accuracy of the target information.

[0026] In addition, an information management system according to the present invention comprises the above-mentioned information monitoring device, a memory unit that stores information, and a storage processing unit that cumulatively stores the repeatedly detected target information in the memory unit.

[0027] According to this configuration, the target information repeatedly detected by the information management system including the above-mentioned information monitoring device is cumulatively stored in the storage unit.

[0028] In addition, the information management system of the present invention includes a memory unit that stores information obtained from the above-mentioned information monitoring device, and a memory processing unit that cumulatively stores the repeatedly detected target information in the memory unit.

[0029] According to this configuration, the information monitoring device may be outside the information management system, and the target information repeatedly detected by the information monitoring device is cumulatively stored in the storage unit.

[0030] It is also preferable that the device further comprises a diagnosis unit that performs diagnosis based on a plurality of pieces of objective information.

[0031] According to this configuration, diagnosis can be performed based on a plurality of pieces of objective information.

[0032] It is also preferable that the measurement subject is a human, the target information is body temperature, and the diagnosis unit determines a fever type from the multiple body temperatures.

[0033] With this configuration, by monitoring a person's body temperature, it is possible to determine the person's fever type.

[0034] In addition, it is preferable that the apparatus further includes an attribute acquisition unit that acquires attribute information indicating attributes of the measurement object, and a diagnostic criteria acquisition unit that acquires diagnostic criteria that serve as the basis for the diagnosis based on the attribute information, and the diagnostic unit performs the diagnosis based on the diagnostic criteria.

[0035] According to this configuration, a diagnosis can be made using diagnostic criteria according to the attributes of the measurement subject, thereby improving the accuracy of the diagnosis.

[0036] It is also preferable that the measurement subject is a human, the target information is a vital sign, and the attribute is at least one of nationality, sex, age, height, weight, and blood type.

[0037] According to this configuration, a person's condition can be diagnosed using diagnostic criteria according to the person's attributes, thereby improving the accuracy of diagnosis.

[0038] In addition, it is preferable that the information monitoring device is given identification information for identifying itself, the storage processing unit associates information blocks containing a plurality of the target information with the identification information and stores them in the storage unit, and the information management system further includes a terminal device capable of requesting processing from the storage processing unit, and the terminal device includes a reading unit that reads the identification information from the information monitoring device, and a request processing unit that obtains the information blocks associated with the identification information read by the reading unit by requesting the storage processing unit.

[0039] According to this configuration, the terminal device can read the identification information from the information monitoring device and obtain the information block associated with the identification information by requesting the storage processing unit. In other words, the target information detected by the information monitoring device and cumulatively stored can be confirmed by the terminal device.

[0040] In addition, it is preferable that the information monitoring device is given identification information for identifying itself, and the memory processing unit associates an information block containing at least one of the multiple target information and the diagnosis result of the diagnosis unit with the identification information and stores it in the memory unit, and the information management system further includes a terminal device capable of requesting processing from the memory processing unit, and the terminal device includes a reading unit that reads the identification information from the information monitoring device, and a request processing unit that obtains the information block associated with the identification information read by the reading unit by requesting the memory processing unit.

[0041] According to this configuration, the terminal device can read the identification information from the information monitoring device and obtain the information block associated with the identification information by requesting the storage processing unit. In other words, it becomes possible to confirm at least one of the target information and the diagnosis result detected and cumulatively stored by the information monitoring device on the terminal device.

[0042] It is also preferable that the terminal device further includes an electronic certification processing unit that assigns an electronic signature to the information block using a private key that pairs with an electronic certificate including a public key, and stores the information block to which the electronic signature has been assigned in the memory unit in association with the identification information, wherein the request processing unit obtains the information block to which the electronic signature has been assigned, which is associated with the identification information read by the reading unit, and the electronic certificate by requesting the memory processing unit, and wherein the terminal device further includes a verification unit that verifies the information block to which the electronic signature has been assigned using the electronic certificate obtained by the request processing unit.

[0043] This configuration makes it possible to prevent tampering with the information block including the cumulatively stored target information, thereby improving the reliability that the detected target information is the information that has been detected continuously.

[0044] In addition, the immigration inspection method of the present invention is an immigration inspection method that uses the above-mentioned information management system, and when a person wearing the information monitoring device enters the country, immigration inspection or quarantine is carried out based on the information block acquired by the terminal device.

[0045] This configuration improves the reliability of the target information detected from a person wearing the information monitoring device being continuously detected information, thereby improving the reliability of immigration inspection or quarantine.

[0046] In addition, the entrance management method of the present invention is an entrance management method that uses the above-mentioned information management system, and includes the steps of selling the information monitoring device as a ticket, and when a person wearing the information monitoring device enters, determining whether or not to allow entry based on the information block acquired by the terminal device.

[0047] This configuration increases the reliability that the target information detected from the person wearing the information monitoring device is continuously detected information, thereby improving the accuracy of determining whether or not to allow entry.

[0048] In addition, the information management program of the present invention causes a computer to function as a memory unit that stores information obtained from the above-mentioned information monitoring device, and a memory processing unit that cumulatively stores the repeatedly detected target information in the memory unit.

[0049] This information management program enables a computer to function as a storage unit, a storage processing unit, and the like. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0052] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals are used to denote the same configuration, and the description thereof will be omitted.

[0053] Fig. 1 is a block diagram showing an example of the configuration of an information management system according to an embodiment of the present invention. The information management system 1 shown in Fig. 1 includes an information monitoring device 2, a wireless communication terminal 3, a server device 4, and a terminal device 5. The wireless communication terminal 3, the server device 4, and the terminal device 5 are communicatively connected via a network N so as to be able to transmit and receive data.

[0054] The information monitoring device 2 is used by being affixed and attached to the body of a person U who is the measurement target. A smartphone used by the person U can be suitably used as the wireless communication terminal 3. The terminal device 5 is expected to be used, for example, for immigration inspection and quarantine at immigration inspection stations, or for admission reception at various venues such as event venues, concert venues, stadiums, movie theaters, and theaters.

[0055] The network N may include various networks, such as a mobile wireless communication base station, a Wide Area Network (WAN), a Local Area Network (LAN), and the Internet.

[0056] The wireless communication terminal 3 is, for example, a wireless terminal device such as a smartphone, a tablet terminal, or a portable personal computer. The wireless communication terminal 3 is capable of wireless communication with the information monitoring device 2 by a relatively short-range wireless communication means such as Bluetooth (registered trademark). The wireless communication terminal 3 also accesses the network N by wireless communication such as mobile communication or WiFi (registered trademark), and is capable of transmitting and receiving data to and from the server device 4 via the network N. The wireless communication terminal 3 relays data communication between the information monitoring device 2 and the server device 4.

[0057] Fig. 2 is a perspective view of the information monitoring device 2 shown in Fig. 1 as seen from the front side. Fig. 3 is a perspective view of the information monitoring device 2 shown in Fig. 2 as seen from the back side. Fig. 4 is an exploded perspective view of the information monitoring device 2 shown in Fig. 2.

[0058] The information monitoring device 2 includes a circuit unit 21 and a holding member 22 that holds the circuit unit 21. The circuit unit 21 has, for example, a rectangular plate shape. The holding member 22 is configured by laminating, for example, a cover sheet 221 (sheet member), an undersheet 222 (sheet member), and an adhesive layer 223 in this order. The circuit unit 21 is sandwiched between the cover sheet 221 and the undersheet 222, thereby holding the circuit unit 21.

[0059] The cover sheet 221 and the under sheet 222 are, for example, transparent, waterproof sheet members that have translucency. For example, a resin sheet such as a polyester film can be used as the cover sheet 221 and the under sheet 222. The cover sheet 221 and the under sheet 222 are, for example, thermally welded or bonded with an adhesive. This seals the circuit unit 21 and provides waterproofing against sweat, rain, hand washing, bathing, and the like.

[0060] The present invention is not limited to the example in which the cover sheet 221 and the under-sheet 222 are laminated together. The holding member 22 may include only one of the cover sheet 221 and the under-sheet 222.

[0061] The adhesive layer 223 has an opening H formed therein so as to avoid the circuit unit 21. The adhesive layer 223 allows the information monitoring device 2 to be attached to the person U's body.

[0062] Before the information monitoring device 2 is attached to the body of the person U, release sheets 224, 225 are attached to the attachment surface M of the adhesive layer 223. The release sheets 224, 225 have light-blocking properties. The release sheets 224, 225 are surface-treated so as to be easily peeled off from the adhesive layer 223. The release sheets 224, 225 are separated into the release sheet 224 and the release sheet 225 so as to be easily peeled off from the attachment surface M.

[0063] The circuit unit 21 is configured by stacking a substantially rectangular plate-shaped circuit board 211 and a sheet-shaped battery 212. Note that the circuit board 211 and the battery 212 are not limited to being stacked, and various arrangements can be adopted.

[0064] A two-dimensional code such as a QR code (registered trademark), a barcode, or another image code 213 is printed on the surface of the circuit unit 21. Each information monitoring device 2 is given an identification information ID for identifying itself from the other information monitoring devices 2. The image code 213 includes information indicating the identification information ID given to the information monitoring device 2. The cover sheet 221 is translucent, and the image code 213 can be read from the outside through the cover sheet 221.

[0065] A temperature sensor 214 and an optical sensor 215 are disposed on the back surface of the circuit unit 21. When the information monitoring device 2 is attached to the person U, the temperature sensor 214 comes into close contact with the body of the person U via the under-sheet 222. In this way, the temperature sensor 214 detects the body temperature T of the person U.

[0066] When the release sheet 224 is attached to the attachment surface M of the adhesive layer 223, the optical sensor 215 is shielded from light and does not detect light. When the release sheet 224 is peeled off from the attachment surface M, the optical sensor 215 detects light in the surrounding environment through the translucent under-sheet 222. When the attachment surface M of the information monitoring device 2 is attached to the person U, the optical sensor 215 is shielded from light in the surrounding environment and does not detect light.

[0067] That is, while the information monitoring device 2 is attached to the person U, the optical sensor 215 does not detect light in the surrounding environment, and when the information monitoring device 2 is peeled off from the person U, light from the surrounding environment enters the optical sensor 215 and is detected. Therefore, the optical sensor 215 can detect that the temperature sensor 214 of the information monitoring device 2 has been detached from the person U and the information monitoring device 2 has moved away from the person U. The optical sensor 215 corresponds to an example of a detachment detection unit.

[0068] Since the information monitoring device 2 can detect the body temperature T of the person U using the temperature sensor 214 while it is attached to the person U, if the optical sensor 215 does not detect that the information monitoring device 2 has moved away from the person U, it is easy to confirm that the body temperature T (information) has been continuously detected after detection of the body temperature T has started.

[0069] Fig. 5 is a block diagram showing an example of an electrical configuration of the circuit unit 21 shown in Fig. 2 and the wireless communication terminal 3 shown in Fig. 1. The circuit unit 21 includes a battery 212, a temperature sensor 214 (sensor), a light sensor 215, a power control unit 216, a communication unit 217, and a control unit 210.

[0070] The temperature sensor 214 is a temperature sensor for measuring the body temperature T (target information) of the person U, and outputs a signal indicating the detected temperature to the control unit 210. The light sensor 215 detects light in the surrounding environment, and outputs a detection signal indicating the detected light to the power control unit 216 and the control unit 210.

[0071] The power control unit 216 is configured using, for example, a transistor, a latch circuit, etc. When the light detection level DL indicated by the detection signal from the light sensor 215 exceeds an on level Lon preset as a level indicating that light in the surrounding environment has been detected, that is, when a predetermined light is detected by the light sensor 215, the power control unit 216 starts supplying power from the battery 212 to each unit in the circuit unit 21.

[0072] The communication unit 217 is a communication interface circuit capable of communicating with the wireless communication terminal 3. As a communication method of the communication unit 217, for example, Bluetooth (registered trademark) which consumes low power may be suitably used.

[0073] The control unit 210 is a so-called microcomputer configured using, for example, a CPU (Central Processing Unit) that executes predetermined logical operations, a RAM (Random Access Memory) that temporarily stores data, memory elements such as non-volatile flash memory, an RTC (Real Time Clock), and peripheral circuits thereof.

[0074] The control unit 210 executes a predetermined program prestored in the memory element, thereby functioning as a start-up control unit 11, a detection control unit 12, a data processing unit 13, and a separation determination unit 14. The above-mentioned RAM and / or the memory element function as a memory unit 15.

[0075] The storage unit 15 stores in advance the identification information ID given to its own information monitoring device 2, that is, the same identification information ID as the identification information ID shown in its own image code 213.

[0076] After a specified light is detected by the light sensor 215, power supply from the battery 212 is started, and the control unit 210 is started, i.e., after the specified light is detected by the light sensor 215, the start-up control unit 11 starts operation of the communication unit 217, the detection control unit 12, the data processing unit 13, and the separation determination unit 14 when the detection level DL indicated by the detection signal from the light sensor 215 falls below the off level Loff indicating that the specified light is not detected, i.e., when the specified light is no longer detected.

[0077] The detection control unit 12 repeatedly acquires the body temperature T detected by the temperature sensor 214 at a predetermined detection interval tw. That is, the detection control unit 12 executes control to cause the temperature sensor 214 to repeatedly detect the body temperature T.

[0078] Furthermore, when the body temperature T corresponds to a specific event that is preset as an event that may be abnormal, for example, when the body temperature T exceeds 37° C., the detection control unit 12 shortens the detection interval tw.

[0079] The data processing unit 13 associates the body temperature T acquired by the detection control unit 12 with date and time information indicating the date and time of detection, and its own identification information ID, and transmits them to the wireless communication terminal 3 via the communication unit 217. Note that the data processing unit 13 may cumulatively store and accumulate the body temperature T acquired by the detection control unit 12 in association with the date and time information in the storage unit 15, and when a certain amount of accumulated data is accumulated, transmit the data collectively from the communication unit 217 to the wireless communication terminal 3.

[0080] After the battery 212 starts supplying power and the control unit 210 starts up, i.e., after the optical sensor 215 detects a specified light, the detection level DL indicated by the detection signal from the optical sensor 215 falls below the off level Loff, i.e., the specified light is no longer detected, and then the detection level DL again exceeds the on level Lon, i.e., the specified light is again detected by the optical sensor 215.The detachment determination unit 14 determines that the temperature sensor 214 of the information monitoring device 2 has been detached from the person U when this occurs, and notifies the person U by having the communication unit 217 transmit detachment information indicating that the information monitoring device 2 has been detached to the wireless communication terminal 3.

[0081] The on-level Lon and the off-level Loff may be detection levels of the same brightness, or the off-level Loff may be a detection level darker than the on-level Lon.

[0082] The detachment determination unit 14 is not limited to an example in which the detachment information is notified by communication. For example, a display such as an LED (Light Emitting Diode) may be provided on the front side of the circuit unit 21, and when the detachment determination unit 14 determines that the temperature sensor 214 of the information monitoring device 2 has been removed from the person U, the detachment determination unit 14 may notify by displaying, for example, by keeping the LED lit.

[0083] The wireless communication terminal 3 includes a first communication unit 31, a second communication unit 32, a touch panel display 33, and a control unit 30. The first communication unit 31 is a communication circuit capable of wireless communication with the communication unit 217 of the information monitoring device 2, and is, for example, a Bluetooth (registered trademark) communication interface circuit. The second communication unit 32 is a communication circuit capable of wireless communication with the server device 4 via the network N, and is, for example, a communication interface circuit for mobile communication, WiFi (registered trademark), or the like.

[0084] The control unit 30 is a so-called microcomputer configured using, for example, a CPU that executes predetermined logical operations, a RAM that temporarily stores data, a memory element such as a non-volatile flash memory, an RTC, and peripheral circuits thereof.

[0085] The control unit 30 executes a predetermined program prestored in the storage element, thereby functioning as a communication control unit 301 and an attribute receiving unit 302. The RAM and / or the storage element of the control unit 30 functions as a storage unit 303. The program may be downloadable from the network N as a so-called application.

[0086] The communication control unit 301 causes the second communication unit 32 to transmit the body temperature T, date and time information, and identification information ID received from the information monitoring device 2 by the first communication unit 31 to the server device 4 via the network N. The communication control unit 301 may cumulatively store the body temperature T, date and time information, and identification information ID received by the first communication unit 31 in the storage unit 303, and when a certain amount of accumulated data is accumulated, cause the second communication unit 32 to transmit them collectively to the server device 4.

[0087] Hereinafter, when the communication control unit 301 causes the first communication unit 31 to transmit and receive information to and from the information monitoring device 2, this may be simply described as the communication control unit 301 transmitting and receiving information to and from the information monitoring device 2, and when the communication control unit 301 causes the second communication unit 32 to transmit and receive information to and from the server device 4 via the network N, this may be simply described as the communication control unit 301 transmitting and receiving information to and from the server device 4.

[0088] Furthermore, when the communication control unit 301 receives the departure information from the information monitoring device 2 , it transmits the departure information to the server device 4 .

[0089] The attribute receiving unit 302 receives input of attribute information from the person U. The attribute information is information that represents the attributes of the person U, such as nationality, sex, age, height, weight, and blood type.

[0090] The communication control unit 301 transmits the attribute information received by the attribute receiving unit 302 to the server device 4 in association with the identification information ID of the information monitoring device 2 of the person U.

[0091] 1, the server device 4 includes an external communication unit 47 and a control unit 40. The external communication unit 47 is a communication interface circuit capable of communicating with the second communication unit 32 of the wireless communication terminal 3 via the network N. The external communication unit 47 receives information transmitted from the communication unit 217 of the information monitoring device 2 and relayed by the wireless communication terminal 3, thereby indirectly receiving information from the communication unit 217.

[0092] The control unit 40 is a so-called microcomputer that is configured using, for example, a CPU that executes predetermined logical operations, a RAM that temporarily stores data, a storage device such as a non-volatile HDD (Hard Disk Drive) or SSD (Solid State Drive), an RTC, and peripheral circuits thereof.

[0093] The control unit 40 executes an information management program pre-stored in the memory element, thereby functioning as a memory processing unit 41, a diagnosis unit 42, an attribute acquisition unit 43, a diagnosis criterion acquisition unit 44, and an electronic certificate processing unit 45. The RAM and / or storage device of the control unit 40 functions as a memory unit 46. The information management program may be stored in a storage medium.

[0094] The storage unit 46 stores a diagnostic criteria table indicating the correspondence between attribute information and diagnostic criteria, which is obtained, for example, statistically in advance.

[0095] The storage processing unit 41 associates the body temperature T, date and time information, and identification information ID received by the external communication unit 47 from the communication unit 217 of the information monitoring device 2 via the wireless communication terminal 3 with each other and cumulatively stores them in the storage unit 46. The storage processing unit 41 stores a plurality of body temperatures T and date and time information associated with the identification information ID in this way as a single information block in the storage unit 46. The information block may be a so-called data file.

[0096] When the storage processing unit 41 receives the departure information from the wireless communication terminal 3, the storage processing unit 41 stores the departure information in the storage unit 46 together with the information block.

[0097] The attribute acquisition unit 43 acquires the attribute information and the identification information ID transmitted from the wireless communication terminal 3 in association with each other, and stores them in the storage unit .

[0098] The diagnostic criterion acquisition unit 44 acquires diagnostic criteria that serve as the basis for diagnosis, based on the attribute information stored in the storage unit 46 .

[0099] The diagnosis unit 42 performs a diagnosis using the diagnostic criteria acquired by the diagnostic criteria acquisition unit 44, based on the body temperature T stored in the memory unit 46. The diagnosis unit 42 also determines the fever type based on the body temperature T stored in the memory unit 46.

[0100] The electronic certification processing unit 45 obtains an electronic certificate and stores it in the memory unit 46, assigns an electronic signature to the information block stored in the memory unit 46, and associates the information block to which the electronic signature has been assigned with an identification information ID and stores them in the memory unit 46. The electronic certification processing unit 45 can obtain an electronic certificate by accessing a certification authority of a third party (not shown) connected to the network N.

[0101] The terminal device 5 is configured using, for example, a personal computer, a tablet terminal, etc. The terminal device 5 includes a control unit 50, a reading unit 54, a display unit 55, and a terminal communication unit 56.

[0102] The terminal communication unit 56 is a communication interface circuit capable of communicating with the external communication unit 47 of the server device 4 via the network N. The display unit 55 is a display device such as a liquid crystal panel or an organic EL panel.

[0103] The reading unit 54 is a reading device that reads the identification information ID from the information monitoring device 2. As the reading unit 54, for example, a camera that reads the identification information ID from the image code 213 can be used.

[0104] The control unit 50 is a so-called microcomputer configured using, for example, a CPU that executes predetermined logical operations, a RAM that temporarily stores data, a storage device such as a non-volatile HDD or SSD, an RTC, and peripheral circuits thereof.

[0105] The control unit 50 functions as a request processing unit 51, a verification unit 52, and an information notification unit 53 by executing a predetermined program stored in advance in the storage device.

[0106] Based on the identification information ID read by the reading unit 54, the request processing unit 51 causes the terminal communication unit 56 to transmit a request for an information block associated with the identification information ID to the server device 4 via the network N. Hereinafter, the act of the request processing unit 51 or the verification unit 52 causing the terminal communication unit 56 to transmit and receive to and from the server device 4 via the network N may be simply described as the request processing unit 51 or the verification unit 52 transmitting and receiving to and from the server device 4, etc.

[0107] In the server device 4 that has received the request, the storage processing unit 41 refers to the storage unit 46 and transmits to the terminal device 5 the information block to which the digital signature has been added and the digital certificate that are associated with the identification information ID.

[0108] In the terminal device 5, the verification unit 52 verifies the digitally signed information block based on the digital certificate.

[0109] The information notification unit 53 notifies the information of the information block by displaying it on the display unit 55, etc. Furthermore, if the verification by the verification unit 52 fails, that is, if there is a possibility that the information block has been tampered with, the information notification unit 53 notifies the failure of the verification by displaying it on the display unit 55, etc.

[0110] This allows the user of the terminal device 5 to check the information in the information block of the person U to whom the information monitoring device 2 with identification information ID is attached from the display on the display unit 55, etc., and can also check whether there is any risk that the information in the information block has been tampered with.

[0111] Moreover, if the information monitoring device 2 is removed from the person U within the preset monitoring period tm, the information block contains removal information. Therefore, the user of the terminal device 5 can confirm that the record of the body temperature T during the monitoring period tm contained in the information block is one that was continuously measured without the information monitoring device 2 being removed. This improves the reliability of monitoring the body temperature T over the monitoring period tm.

[0112] Next, an example of the operation of the information management system 1 when applied to immigration inspection will be described. Figures 6 and 7 are flowcharts showing an example of the operation of the information monitoring device 2. First, a person U who intends to travel from country A to country B obtains the information monitoring device 2.

[0113] Then, the person U peels off the release sheet 224 from the information monitoring device 2 (step S1). Since the release sheet is separated into the release sheet 224 and the release sheet 225, the person U can hold the part to which the release sheet 225 is attached in his / her hand and peel off the release sheet 224. This makes it easy to peel off the release sheet 224 from the information monitoring device 2.

[0114] When the release sheet 224 is peeled off from the information monitoring device 2, the optical sensor 215 is no longer shielded from light in the surrounding environment, and therefore the optical sensor 215 detects light in the surrounding environment (step S2).

[0115] Then, when the detection level DL of the light sensor 215 exceeds the on level Lon, i.e., when a specified light is detected (YES in step S3), the power control unit 216 starts supplying power from the battery 212 to the control unit 210, the temperature sensor 214, and the communication unit 217 (step S4).

[0116] This allows the power supply from the battery 212 to be cut off until the release sheet 224 is peeled off from the information monitoring device 2, reducing the risk of the battery 212 becoming depleted while the information monitoring device 2 is stored without being used.

[0117] Next, the person U attaches the adhesive layer 223 from the portion where the release sheet 224 has been peeled off to the body of the person U, and peels off the release sheet 225 to attach the entire adhesive layer 223 to the body of the person U. In this way, the information monitoring device 2 is attached to the body of the person U (step S5).

[0118] In this way, the part where the release sheet 225 has not been peeled off can be held in the hand and the adhesive layer 223 of the part where the release sheet 224 has been peeled off can be attached to the body of person U, and then the release sheet 225 can be peeled off and the entire adhesive layer 223 can be attached to the body of person U, making it easy to attach the information monitoring device 2 to the body of person U.

[0119] When the information monitoring device 2 is attached to the body of the person U, the temperature sensor 214 and the light sensor 215 are in intimate contact with the body of the person U via the under-sheet 222 .

[0120] When the optical sensor 215 comes into close contact with the body of the person U, light from the surrounding environment does not enter the optical sensor 215. As a result, when the detection level DL of the optical sensor 215 falls below the off level Loff, that is, when the predetermined light is no longer detected (YES in step S6), the start-up control unit 11 starts the operation of the communication unit 217, the detection control unit 12, the data processing unit 13, and the separation determination unit 14. This starts the execution of step S7 and subsequent steps.

[0121] According to the start-up control unit 11, after the peel-off sheet 225 is peeled off, the sensor 215 detects light in the surrounding environment and power supply from the battery 212 is started, the information monitoring device 2 waits until it is attached to the body of the person U and the temperature sensor 214 can detect the body temperature T, and then the body temperature T is acquired, thereby reducing the risk that the environmental temperature before the information monitoring device 2 is attached to the body of the person U will be erroneously detected as the body temperature T.

[0122] Next, the communication unit 217 executes a communication connection process to enable communication with the wireless communication terminal 3 (step S7).

[0123] 8 is a flowchart showing an example of the operation of the wireless communication terminal 3. The communication control unit 301 executes a communication connection process with the information monitoring device 2, and when communication becomes possible (YES in step S31), the communication control unit 301 receives the identification information ID from the information monitoring device 2 (step S32), and the attribute receiving unit 302 receives input of attribute information related to the person U (step S33).

[0124] The attribute receiving unit 302 displays a message on the touch panel display 33, for example, prompting the person U to input attribute information, such as “Please enter your nationality, sex, age, height, weight, and blood type,” and receives the attribute information input by the person U by operating the touch panel display 33.

[0125] The attribute receiving unit 302 associates the attribute information thus obtained with the identification information ID acquired from the information monitoring device 2, and transmits them to the server device 4 (step S34).

[0126] Thereafter, the wireless communication terminal 3 transmits the information transmitted from the information monitoring device 2 to the server device 4 and relays the communication between the information monitoring device 2 and the server device 4 (step S35). This allows the information monitoring device 2 to transmit information to the distant server device 4 using the communication unit 217 of a communication method with short communication distance and low power consumption, such as Bluetooth (registered trademark), making it easy to reduce the power consumption and cost of the information monitoring device 2.

[0127] 7, in the information monitoring device 2, the temperature sensor 214 detects the body temperature T of the person U, and the detection control unit 12 acquires the detected body temperature T (step S11).

[0128] Next, the data processing unit 13 associates the body temperature T acquired by the detection control unit 12 with date and time information indicating the date and time when the body temperature T was acquired, and the identification information ID, and transmits them to the wireless communication terminal 3 (step S12).

[0129] Then, in the wireless communication terminal 3, the body temperature T, the date and time information, and the identification information ID are transmitted to the server device 4 by the communication control unit 301 (step S35).

[0130] Next, in the information monitoring device 2, the detection control unit 12 compares the body temperature T with a preset specific body temperature Ts (step S13). The specific body temperature Ts may be, for example, 37.0°C, which is a body temperature that may be a fever, which is an example of an abnormality.

[0131] If the body temperature T exceeds the specific body temperature Ts (YES in step S13), the detection control unit 12 shortens the detection interval tw from the current value (step S14) and proceeds to step S15. On the other hand, if the body temperature T does not exceed the specific body temperature Ts (NO in step S13), the detection control unit 12 maintains the current detection interval tw without executing step S14 and proceeds to step S15.

[0132] When the body temperature T exceeds a specific body temperature Ts (e.g., 37.0°C), this is an event that may be abnormal, and corresponds to an example of a specific event. Note that the specific body temperature Ts is not limited to 37.0°C, and may be set appropriately depending on the monitoring purpose of the information monitoring device.

[0133] When the detection interval tw is shortened, the detection frequency of the body temperature T is increased in step S17 described later. This reduces the detection frequency of the body temperature T or the communication frequency to reduce power consumption and communication load, while increasing the detection frequency of the body temperature T when there is a high possibility of an abnormality, thereby improving the monitoring accuracy of the body temperature T.

[0134] Next, in step S15, the detachment determination unit 14 compares the detection level DL of the optical sensor 215 with the on level Lon (step S15). Then, when the detection level DL exceeds the on level Lon (YES in step S15), the detachment determination unit 14 transmits detachment information indicating that the information monitoring device 2 has been detached from the person U to the wireless communication terminal 3 together with the identification information ID (step S16).

[0135] Then, in the wireless communication terminal 3, the communication control unit 301 transmits the separation information and the identification information ID to the server device 4 (step S35).

[0136] When the detection level DL exceeds the on level Lon (YES in step S15), it means that the light sensor 215 has detected light, and it is considered that the information monitoring device 2 has been detached from the person U and light from the external environment has entered the light sensor 215. Therefore, when the detection level DL exceeds the on level Lon (YES in step S15), by transmitting detachment information to the wireless communication terminal 3 (step S16), it is possible to notify the server device 4 via the wireless communication terminal 3 that the information monitoring device 2 has been detached from the person U.

[0137] Next, the detection control unit 12 checks whether the detection interval tw has elapsed since the previous detection of the body temperature T in step S11 (step S17). If the detection interval tw has not yet elapsed (NO in step S17), steps S15 to S17 are repeated to monitor whether the information monitoring device 2 is removed from the person U.

[0138] On the other hand, if the detection interval tw has elapsed (YES in step S17), steps S11 to S17 are repeated again. This makes it possible to continuously detect the body temperature T at the detection interval tw and to continue transmitting the body temperature T to the server device 4.

[0139] Fig. 9 and Fig. 10 are flowcharts showing an example of the operation of the server device 4 shown in Fig. 1. First, the storage processing unit 41 receives the identification information ID and attribute information of the information monitoring device 2 via the wireless communication terminal 3, and stores the attribute information in the storage unit 46 in association with the identification information ID (step S41).

[0140] Next, the memory processing unit 41 receives the identification information ID, date and time information, and body temperature T of the information monitoring device 2 via the wireless communication terminal 3, and cumulatively stores the date and time information and body temperature T in the memory unit 46 as an information block in association with the identification information ID (step S42).

[0141] The information management system 1 can include multiple information monitoring devices 2, and the server device 4 can execute the following processes corresponding to the identification information ID of each information monitoring device 2. However, in the following explanation, for ease of explanation, the operation targeted at one information monitoring device 2 will be explained.

[0142] Next, the storage processing unit 41 checks whether or not the leaving information has been received (step S43). If the leaving information has been received (YES in step S43), the storage processing unit 41 adds the leaving information to the information block of the identification information ID corresponding to the received leaving information (step S44).

[0143] As a result, the information block stores information that the information monitoring device 2 with the identification information ID was removed from the body of the person U during the monitoring period tm. In other words, it becomes clear that it cannot be guaranteed that the body temperature T in the information block including the removal information is the body temperature T of the same person continuously measured during the monitoring period tm.

[0144] On the other hand, if the departure information has not been received (NO in step S43), the storage processing unit 41 moves the process to step S45 without adding the departure information to the information block.

[0145] In step S45, the memory processing unit 41 checks whether or not the monitoring period tm has elapsed since the body temperature T of the identification information ID was first received (step S45). If the monitoring period tm has not elapsed (NO in step S45), steps S42 to S45 are repeated again.

[0146] If the monitoring period tm has elapsed (YES in step S45), the diagnostic criterion acquisition unit 44 acquires diagnostic criteria based on the attribute information corresponding to the identification information ID (step S46).

[0147] Specifically, the diagnostic criteria acquisition unit 44 can acquire the diagnostic criteria, for example, in the following manner. Fig. 11 is an explanatory diagram showing an example of a diagnostic criteria table stored in advance in the storage unit 46. Diagnostic criteria table A shown in Fig. 11 includes nationality, sex, age, height, and blood type as attributes. Then, normal body temperature and its variation range, which represent the diagnostic criteria, are associated with combinations of these attributes.

[0148] The diagnostic criteria table A can be obtained, for example, by measuring body temperatures T for a certain period of time for people with various attributes and statistically processing the measurement results.

[0149] In step S46, for example, if the attributes of person U are nationality: Japanese, gender: male, age: 20, height: 170, and blood type: O, the diagnostic criteria acquisition unit 44 can refer to diagnostic criteria table A to obtain a normal body temperature of 36.5°C and a judgment criterion of 36.1 to 36.9°C with a fluctuation range of ±0.4.

[0150] Next, the diagnosis unit 42 diagnoses the body temperature T of the information block corresponding to the identification information ID based on the diagnosis criteria obtained in step S46 (step S47). Specifically, if all of the body temperatures T detected during the monitoring period tm included in the information block corresponding to the identification information ID are within the range of the judgment criteria of 36.1 to 36.9°C, the diagnosis unit 42 diagnoses them as normal (YES in step S51), and adds a diagnosis result indicating normal to the information block of the identification information ID (step S52).

[0151] On the other hand, if any one of the body temperatures T detected during the monitoring period tm and included in the information block corresponding to the identification information ID is outside the judgment criteria range of 36.1 to 36.9°C, it is diagnosed as abnormal (NO in step S51), and the fever type is determined for the body temperature T in the information block of the identification information ID (step S53).

[0152] 12 to 16 are explanatory diagrams showing examples of fever patterns. FIG. 12 is a graph showing a fever pattern known as persistent fever, in which a high fever continues with a daily body temperature difference of within 1°C. FIG. 13 is a graph showing a fever pattern known as remittent fever, in which a daily body temperature difference fluctuates by 1°C or more and does not fall below 37°C. FIG. 14 is a graph showing a fever pattern known as intermittent fever, in which high and normal fevers alternate at regular intervals and there is a large difference in body temperature. FIG. 15 is a graph showing a fever pattern known as undulating fever, in which fever periods and afebrile periods are repeated irregularly. FIG. 16 is a graph showing a fever pattern known as periodic fever, in which fevers are repeated at regular intervals.

[0153] In step S53, the diagnosis unit 42 judges whether the body temperature T in the information block of the identification information ID corresponds to any one of persistent fever, relaxation fever, intermittent fever, undulating fever, and periodic fever. Then, the diagnosis unit 42 adds the diagnosis result indicating an abnormality and information indicating the fever type to the information block of the identification information ID (step S54).

[0154] Residual fever is known to occur in lobar pneumonia, the peak of typhoid fever, chestnut tuberculosis, and meningitis. Remittent fever is known to occur in suppurative diseases, septicemia, the fever phase of typhoid fever, viral diseases, malignant tumors, and pulmonary tuberculosis. Intermittent fever is known to occur in malaria and relapsing fever. Undulating fever is known to occur in brucellosis, malaria, Hodgkin's disease, kidney stones, biliary atresia, and others. Periodic fever is known to occur in malaria and steroid fever.

[0155] In this way, since fever type and disease are related, determining the fever type can provide a clue for predicting the disease of person U.

[0156] Next, the electronic certification processing unit 45 assigns an electronic signature to the information block of the identification information ID, and stores the information block with the electronic signature in the memory unit 46 in correspondence with the identification information ID (step S55), and thereafter terminates the processing until a request is received from the terminal device 5.

[0157] The electronic certification processing unit 45, for example, obtains in advance from a certification authority an electronic certificate including a public key and a private key corresponding to the electronic certificate, and stores them in the storage unit 46. The electronic certificate also includes information indicating the certification authority. Using this private key, an electronic signature can be applied to the information block of the identification information ID.

[0158] Next, the operation of the information management system 1 when a person U undergoes immigration after traveling abroad will be described. The following describes a case where a terminal device 5 is installed at an immigration inspection station, for example, and an immigration inspector uses the terminal device 5. Fig. 17 is a flowchart showing an example of the operation of the terminal device 5 shown in Fig. 1.

[0159] First, when a traveling person U arrives at an immigration inspection station to enter the country, an immigration inspector reads the image code 213 of the information monitoring device 2 attached to the body of the person U using the reading unit 54. As a result, the identification information ID of the information monitoring device 2 attached to the body of the person U is read by the reading unit 54 (step S61).

[0160] Next, the request processing unit 51 requests the storage processing unit 41 of the server device 4 to send an information block corresponding to the identification information ID read by the reading unit 54 and a digital certificate including a public key (step S62).

[0161] Then, the server device 4 receives the request from the request processing unit 51, and the memory processing unit 41 reads out the information block corresponding to the requested identification information ID and the electronic certificate from the memory unit 46 and transmits them to the terminal device 5.

[0162] In the terminal device 5, the request processor 51 acquires the information block and the digital certificate received from the server device 4 (step S63).

[0163] Next, the verification unit 52 verifies the information block corresponding to the identification information ID based on the received electronic certificate (step S64).

[0164] For example, the verification unit 52 refers to information indicating a certificate authority included in the electronic certificate, and accesses the certificate authority to confirm the validity of the electronic certificate. If the electronic certificate is invalid, the verification fails (NO in step S65). If the electronic certificate is valid, the verification unit 52 decrypts the electronic signature added to the information block to obtain a hash value. Furthermore, the verification unit 52 refers to the hash value of the information block, and if it matches the hash value obtained from the electronic signature, the verification is successful (YES in step S65), and if it does not match, the verification fails (NO in step S65).

[0165] If the verification fails (NO in step S65), the information notification unit 53 notifies the person U of the failure of the verification by, for example, displaying the same on the display unit 55 (step S66), and the process proceeds to step S67. This enables the immigration officer to deny entry to the person U since the record of the person U's body temperature T is unreliable.

[0166] On the other hand, if the verification is successful (YES in step S65), the process proceeds to step S67 without executing step S66.

[0167] In step S67, the information notification unit 53 checks whether or not the information block of the identification information ID received from the server device 4 includes departure information (step S67). If departure information is included (YES in step S67), the information notification unit 53 notifies the user that the information block includes departure information or that the record of the body temperature T of the person U is unreliable, for example, by displaying this on the display unit 55 (step S68), and proceeds to step S69.

[0168] On the other hand, if the departure information is not included (NO in step S67), the information notification unit 53 moves the process to step S69 without executing step S68.

[0169] If the information block contains departure information (YES in step S67), there is a possibility that the information monitoring device 2 was removed from the person U during the monitoring period tm. As a result, the body temperature T contained in the information block may be missing during the monitoring period tm without being detected, or may be the body temperature T of another person other than the person U because the information block was attached to someone other than the person U. Therefore, if it is notified in step S68 that the information block contains departure information or that the record of the person U's body temperature T is unreliable, the immigration officer can refuse entry to the person U because the record of the person U's body temperature T is unreliable.

[0170] Note that the information notification unit 53 is not limited to displaying information such as verification failure or withdrawal information on the display unit 55 in steps S66 and S68. For example, the information notification unit 53 may notify the user by issuing an alarm.

[0171] In step S69, the information notification unit 53 causes the display unit 55 to display the diagnosis result and the body temperature T during the monitoring period tm, which are included in the information block of the identification information ID (step S69). This allows the immigration officer to refuse entry to the person U if the diagnosis result indicates an abnormality. Furthermore, if the immigration officer checks the body temperature T of the person U during the monitoring period tm and determines that there is a suspicion of an infectious disease, the immigration officer can refuse entry to the person U. Alternatively, the terminal device 5 or the server device 4 may determine whether entry is permitted.

[0172] For example, it is assumed that, for the purpose of preventing the spread of an infectious disease such as a virus, the entry of a person U from country A, where an infectious disease is spreading, into country B will be restricted. In this case, for example, in country A, person U will be able to attach an information monitoring device 2 to his / her body for a monitoring period tm (e.g., 14 days) before leaving the country, and when the monitoring period tm has elapsed, travel to country B and undergo immigration inspection or quarantine in country B.

[0173] In this case, immigration inspectors and quarantine officers can use terminal device 5 to confirm, upon entry into Country B, that the body temperature T during the monitoring period tm before entry into Country B has been continuously detected, making it possible to effectively impose entry restrictions to prevent infection.

[0174] Furthermore, for example, by conducting a PCR (Polymerase Chain Reaction) test on person U before he leaves country A, and using the results of the PCR test and his body temperature T during the monitoring period tm obtained by the information monitoring device 2, the reliability of confirming whether person U is infected or not can be improved. As a result, it becomes easy to shorten the waiting period after person U enters country B, or to eliminate the need for waiting.

[0175] Next, a description will be given of a method for managing admission to an event venue or the like using the information management system 1. When managing admission to an event venue or the like using the information management system 1, it is preferable to sell the information monitoring devices 2 as tickets.

[0176] For example, it is preferable to sell the information monitoring device 2 by printing necessary information for a ticket, such as "XX concert ticket, date: X year, X month, X day," on the surface of the sheet member of the information monitoring device 2 so as not to overlap with the image code 213. Then, the person U who purchased the ticket wears the information monitoring device 2 on his / her body for a monitoring period tm (for example, 14 days) before the event or the like is held. On the day of the event or the like, an admission manager reads the image code 213 using the reading unit 54 of the terminal device 5 at the entrance to the venue of the event or the like. Furthermore, the admission manager may use the terminal device 5 to obtain the body temperature T, diagnosis results, and withdrawal information of the person U during the monitoring period tm from the server device 4, and may determine whether or not the person U is allowed to enter based on this information, the verification results, and the like. Alternatively, the terminal device 5 or the server device 4 may determine whether or not the person U is allowed to enter.

[0177] In this way, by using the information management system 1 to manage admission to events, etc., it is possible to prevent the entry of people U suspected of having an infectious disease, etc. based on their body temperature T during the monitoring period tm, thereby effectively managing admission to prevent infection.

[0178] When admission management is performed using the information management system 1, the information monitoring device 2 itself does not necessarily have to be the ticket. The information monitoring device 2 may be attached to the body of the person U who purchased the ticket, separately from the ticket.

[0179] The target information is not limited to the body temperature T. The target information may be, for example, vital signs such as heart rate, pulse rate, blood pressure, pulse pressure, electrocardiogram, blood oxygen concentration, and respiratory rate. In addition, the measurement subject is not limited to a person, and the target information is not limited to vital signs.

[0180] For example, it is assumed that the measurement target is vintage wine and the target information is temperature. The information monitoring device 2 is attached to a bottle of vintage wine to monitor the temperature of the wine, and when selling the wine, the temperature history recorded in the server device 4 can be shown to the purchaser using the terminal device 5. This makes it possible to show the purchaser that the expensive vintage wine has been appropriately temperature-controlled, thereby adding value through quality control.

[0181] Furthermore, the removal detection unit is not limited to the optical sensor 215 as long as it can detect that the temperature sensor 214 has been removed from the measurement target. Instead of the optical sensor 215, a contact sensor, for example, may be used as the removal detection unit.

[0182] Moreover, the temperature sensor 214 may be used as the detachment detection unit instead of the optical sensor 215. Then, when the body temperature T detected by the temperature sensor 214 exceeds a temperature considered to be a human body temperature, for example, 35° C., and then falls below a temperature that is not usually considered to be a human body temperature, for example, 33° C., the detachment determination unit 14 may determine that the information monitoring device 2 has been detached, and transmit detachment information to the wireless communication terminal 3 in step S16.

[0183] Moreover, instead of the optical sensor 215, a sensor that detects objective information other than temperature may be used as the removal detection unit, and removal of the sensor from the measurement target may be detected based on the objective information.

[0184] The detachment detection unit may be a member that detects that the information monitoring device 2 including the sensor has been detached from the measurement target by generating a predetermined pattern or changing color when at least a part of the sheet member constituting the holding member 22 is peeled off after being attached to the measurement target.
