Ultraviolet (UV) radiation is the most energetic part of the optical radiation emitted by the sun. The UV radiation is divided into the three classes: UV-A, UV-B and UV-C radiation. Only the UV-A and UV-B radiation, which have a wavelength of 400 to 315 nm or 315 to 280 nm, reach the earth's surface. The UV-C radiation with a wavelength of 280 to 100 nm is filtered through the atmosphere. UV radiation is the leading cause of skin cancer, v. a. among the fair-skinned population. Also, therefore, the weather services, z. For example, the German Weather Service (DWD) introduced the UV index (UVI) as an international environmental parameter. The UVI provides an indication of whether protective measures are required and estimates the likelihood of sunburn regardless of skin type. From the UVI can be derived the time span, which one should spend unprotected maximally in the sun. It is currently not possible to verify compliance with these recommended times. There are currently UV sensors available on the market. a. in the accessory program for mostly privately used weather stations.

B. using geographic data such as location and / or time can determine a sun elevation angle and from this a spectral distribution of the radiation. To DIN 5050 it can be used to calculate a time that the creature can spend maximally in the sun. Additional factors such as skin type, age, weather - eg, cloudiness -, a certain activity, eg. B. swimming, etc., can be taken into account.

In particular, in the form of a plaster, a user can the dosimeter for measuring the UV intensity freely on the body, in a place that is not affected by hair, clothing o. Ä. is hidden, place. The user has the opportunity at any time to inform himself about the individual time he should remain in the sun. If the recommended time is exceeded, the user can be warned about an alarm signal. By a according to an embodiment integrated into the dosimeter communication module, it is also possible for the user, the measured actual data z. B. to another device, in addition to the smartphone z. B, to a tablet PC, to a base station of a telemedical system and / or to a router. There, the data can either be evaluated and be displayed or forwarded to a database on the Internet. The database can store the data z. B. a telemedicine center, a hospital, a respective family or specialist or a social network.

The present invention of the dosimeter, in particular in the form of an electronic patch, can therefore enable the user to determine the maximum time recommended for him in the sun and to monitor it. The technical solution presented here can help reduce the number of people suffering from sunburn, UV-related skin irritation and skin cancer.

A dosimeter for determining and / or monitoring a residual sun exposure time on a skin of a living being until a predetermined dose of exposure to the sun has reached the following features:
An interface to a read UV sensor detecting a UV radiation value representing a dose rate of UV radiation incident on the subject's skin; and
a data processing unit for determining the solar residual exposure time based on the UV radiation value and / or a future estimated UV radiation value, the solar residual exposure time representing a time that the subject's skin is susceptible until the predetermined dose of sun exposure is reached.

The dosimeter can be a measuring device for measuring a radiation dose, in this case a UV radiation dose acting on a skin of a living being. In particular, the dosimeter proposed here may be designed to be worn on the human or animal body and, in the case of an application in humans, be referred to as a personal dosimeter. The dosimeter can be worn on areas of the skin that are exposed to sunlight outdoors. The residual sun exposure time can be a time for which a wearer of the dosimeter can, under unchanged conditions, continue to be exposed to the UV radiation of the sun, without having to expect any damage to the health of the skin. With a lapse of the period of exposure to the sun, a wearer of the dosimeter is required to either dwarf the sun or enter an interior, or rub the skin containing the dosimeter with a suitable sunscreen product, or, e.g. B. to cover with a piece of clothing or towel to avoid damage to the skin. The Sonnenresteinwirkzeit the user or carrier z. Example, be communicated via a display of a dockable with the dosimeter mobile device, such as a smartphone. The solar residual exposure time can be given in minutes, for example. The sun exposure dose can be understood as meaning a maximum of UV radiation that can be supplied to the skin under predetermined conditions in a specific period of time without damaging the skin.

The UV sensor may be a sensor which is designed to quantitatively detect a prevailing UV radiation by means of a physical or chemical effect for the determination of the UV radiation value and to convert it into an electrical signal, for example. The electrical signal can then be used by the data processing unit coupled or coupleable to the dosimeter. The value of UV radiation can be understood to be an integral value since it depends on factors influencing UV radiation, such as the prevailing weather conditions and the time of day. Under the dose rate, the sun exposure dose per unit time, e.g. As hours, minutes and / or seconds to be understood. The UV sensor can be structurally integrated into the dosimeter, or be used as an external measuring device, and be coupled in this case, for example by cable via a plug connection or wirelessly by means of the interface with the dosimeter. In the embodiment as an external sensor, the UV sensor may be installed in a garment or other fashion accessory. It may be z. For example, a pair of sunglasses, a headgear, a bracelet, a necklace or a wristwatch, etc. act. The external UV sensor can communicate through a wireless connection with the central processing unit of the dosimeter via the interface. In one embodiment, the dosimeter may include an integrated UV sensor and additionally an external UV sensor.

In the data processing unit, which can also be referred to as a central processing unit (ZVE), it may, for. B. may be a microcontroller. For example, the data processing unit may employ a suitable algorithm to determine the solar residual exposure time based on the UV radiation value and / or the UV radiation value estimated for the future. An algorithm can also be used to estimate the future UV radiation value. The estimation of the future algorithm may be based on the UV radiation value and, under certain circumstances, including prognostic values read into the data processing unit. B. done for the weather. The determination of the solar residual exposure time may be made with respect to a predetermined time frame. For example, the central processing unit can be installed directly in the dosimeter. The electronic components can be equipped with a flexible printed circuit, so that the carrier structure for the electronics can adapt to the body shapes. Alternatively, electronics and printed circuit boards can also be printed ("printed electronics"), thus also providing flexible electronics that can adapt to body shapes, which are particularly suitable for dressings Here, the structural design can be designed in such a way that the central processing unit can be detachably attached to a carrier element of the dosimeter, for example by means of a Velcro strip or the like, in which case the ZVE can be reused several times.

According to one embodiment, the dosimeter is formed as a patch with an adhesive layer to be removably applied to the skin of the animal. The adhesive layer can be an adhesive layer arranged on a lower side of the dosimeter with which the dosimeter designed as a patch can be safely and durably applied to the skin and easily removed again when the dosimeter is no longer needed. The advantage of the embodiment as a patch is that the dosimeter can be readily attached to any body site - as compared to, for example, a dosimeter designed as a bracelet. Furthermore, a plurality of patches can be used, which can be attached to different parts of the body. This is useful because, for example, the skin on the arms and legs is more robust to UV radiation than the skin on the face and neck. This allows the user to obtain individual values and information on different body zones and to provide individually suitable protection for them. In the form of a plaster, the dosimeter is also a disposable product which can be produced at low cost and is easy to replace.

Furthermore, the dosimeter may have an interface connectable or connected to the data processing unit for receiving and / or outputting data. The integration of such an interface into the dosimeter allows advantageous communication of the dosimeter with external devices for the purpose of an information exchange advantageous to the user of the dosimeter. Via the interface, the dosimeter can transmit, for example, data obtained in the data processing unit to a database on the Internet or transmit information from the database to the data processing unit.

For example, the interface can be designed to receive data from a communication module coupled to the dosimeter or coupleable to the dosimeter and / or to send data to the communication module coupled to the dosimeter or coupleable to the dosimeter. In this embodiment, the dosimeter may be used for machine-machine interaction. For example, the communication module may be a smartphone whose connection to the dosimeter can be wireless or wired. Thus, advantageously, an interaction with the user take place without the dosimeter needing to have a display device for it. The dosimeter in the form of a patch for measuring the UV intensity can be such an independent accessory for z. B. be a smartphone.

The dosimeter or a database on the Internet can in this way z. For example, send tips on the right behavior in the sun to the smartphone, where they can be displayed to the user on a display of the smartphone. This embodiment offers the advantage that the dosimeter can be manufactured particularly cost-effectively and used flexibly. For example, the user can be provided with a real-life interface for a social network or a computer game. The goal of the game can z. Example, be exposed to sunlight or a certain dose of UV radiation for exactly a certain (maximum) time. Points could also be collected by behaving according to the provided hints.

For example, the communication module may also be a GSM or EDGE or HSPA module capable of communicating with the Internet itself. In particular, then there is the possibility of retrieving the data that would normally enter the user himself, from the Internet, for. From an electronic patient record, a social network, a hospital information system, etc.

In accordance with a further embodiment, the interface can be designed to receive data of an input module coupled to the dosimeter or coupled to the dosimeter. In this embodiment, the dosimeter can be used for a human-machine interaction, without requiring an external device such. B. requires a smartphone. The input module can have, for example, keys and / or a display device via which the user can make personal entries into the dosimeter. An electronics for the input module can be installed directly in the pavement. In this case, the electronic components can optionally be fitted on a flexible conductor track, so that a support structure for the electronics body shapes of the user can adapt. Alternatively, the structural design can be designed in such a way that the electronics by means of Velcro o. Ä. attach to a support element of the dosimeter and replace leaves. In this case, the electronics can be used multiple times. This embodiment may be the user z. B. enable the dosimeter at a self-selected time to turn on or off for a measurement of UV radiation relevant information, eg. For example, a scheduled activity to enter into the dosimeter. In particular, this embodiment has the advantage that it can be dispensed with an external device, but the user can still personalize the dosimeter.

Furthermore, according to an embodiment of the present invention, the dosimeter may have an output unit connectable or connected to the data processing unit for outputting a visual and / or audible and / or haptic warning relating to an expiration of the solar residual exposure time to a user of the dosimeter. For example, this warning can be output by means of text information on the display device or the display of the dosimeter. Furthermore, the warning can also be effected by means of an alarm tone which can be output via a loudspeaker integrated into the dosimeter or via a loudspeaker of a smartphone connected to the dosimeter. A haptic warning signal, z. B. in the form of acting on the skin of the wearer vibrating the dosimeter, can be realized via appropriate elements installed in the dosimeter. This embodiment is particularly advantageous for the eventuality that the user of the dosimeter fails to check at regular intervals his still available Sonnenresteinwirkzeit, for example, because he was distracted by an activity or fell asleep during the sunbathing.

In another embodiment, the dosimeter may further include another sensor configured to detect and / or determine a skin type of a wearer of the dosimeter and to communicate to the central data processing unit. This embodiment offers the advantage that, with the information about the skin type of the wearer, another important factor is available for determining the individual solar residual exposure time, which can also be made available to the data processing unit even if the dosimeter does not have an input module. Also, any incorrect input of the skin type by the user due to lack or lack of information can be effectively prevented in this way.

A method of determining and / or monitoring a residual sun exposure time on a subject's skin until a predetermined dose of exposure to the sun has reached the following steps comprises:

Reading a UV radiation value representing a dose rate of UV radiation incident on the subject's skin; and

Determining the solar residual exposure time based on the UV radiation value and / or a future estimated UV radiation value, wherein the solar residual exposure time represents a time that the subject's skin is susceptible until the predetermined dose of sun exposure is reached.

The reading-in step may comprise reading in data from one or more UV sensors incorporated in the dosimeter. The reading-in step can be carried out for the first time, for example, by switching on the dose meter. The switching can be done for example by a manual input of the user or automatically, for. For example, when a wearer of the dosimeter steps out of an interior space and the UV sensor is activated by being exposed to solar radiation. The step of determining the solar residual exposure time can take place in a data processing unit installed in the dosimeter and coupled to the UV sensor by means of a suitable algorithm. The steps of reading in and of determining can be carried out, for example, at predetermined time intervals or alternatively or additionally, for example. B. at the request of the user of the dosimeter, for example by means of a manual input of the user in the dosimeter done. Thus, the user of the dosimeter is always a reasonably current value of the remaining individual Sonnenresteinwirkzeit available.

According to one embodiment, data of a geostationary positioning system can be read in the step of reading, wherein in the step of the read-in Determining the solar residual exposure time is further determined based on the data of the geostationary positioning system. The Geostationary Location System data may be, for example, a current geographic location value and / or a current geographic time value. In this way, such important factors as weather conditions related to the geographical location value or a position of the sun based on the geographical location and / or a time of day relating to the time of day can be incorporated into the calculation of the residual sunshine time and thus make them even more accurate. So z. B. the Sonnenresteinwirkzeit if cloudy at the time of detection of the sky at the whereabouts of the wearer of the dosimeter and / or the highest sun is already exceeded.

Further, in the step of reading in supplementary data related to a characteristic of the skin and / or to environmental conditions of the skin, in the step of determining the remaining sun exposure time is further determined based on the additional data. For example, the supplemental data may provide information about a skin type or an activity of a wearer of the dosimeter exercised at the time of acquisition to the data processing unit. For example, if the wearer of the dosimeter belongs to the very sun-sensitive Scandinavian skin type, or if he stays in the water at the time of detection, then the individual sun-hold exposure time is shortened. In this way, the Sonnenresteinwirkzeit can be determined even more accurate.

Also, the method may include a step of outputting the UV radiation value to an external device and / or to a database. For example, the dosimeter may send the current UV measurement data acquired by the UV sensor and / or the geostationary positioning system and / or a current position determined by the geostationary positioning system to a service providing a prediction and thus updating the prediction. Alternatively, the feedback can be sent to another location.

According to a further embodiment, the dosimeter or an app installed on the smart phone coupled to the dosimeter can, according to the individual data and the current measurement data, be a quantity necessary for a user of the dosimeter and / or a necessary specification of a suitable sunscreen substance for the time that the Users in the sun, determine. The required quantity or specifications, for example specifying the appropriate sun protection factor (SPF) and / or UV-A level, may be output on a display of the dosimeter or smartphone. With this embodiment, the user can be more effectively protected against sun damage.

In a continuation of the embodiment described above, the dosimeter may be associated with an electrically controllable pump, the z. B. may be attached to a container of a sunscreen liquid, for. B. screwed or clipped. The pump may be designed to deliver a recommended amount of sunscreen, possibly in several portions. For this purpose, the user can on the smartphone or a likewise integrated into the unit on the container display instructions how and where he has to apply the sunscreen. This embodiment is particularly useful when children are carriers of the dosimeter, as they are usually not aware of the importance of adequate and timely creaming when staying in the sun or not sufficiently aware.

The present invention further provides a control device which is designed to implement or implement the steps of the method according to the invention in corresponding devices. Also by this embodiment of the invention in the form of a control device, the object underlying the invention can be achieved quickly and efficiently.

In the present case, a control device can be understood as meaning an electrical device which processes sensor signals and outputs control and / or data signals in dependence thereon. The control unit may have an interface, which may be formed in hardware and / or software. In the case of a hardware-based design, the interfaces can be part of a so-called system ASIC, for example, which contains various functions of the control unit. However, it is also possible that the interfaces are their own integrated circuits or at least partially consist of discrete components. In a software training, the interfaces may be software modules that are present, for example, on a microcontroller in addition to other software modules.

A computer program product with program code which can be stored on a machine-readable carrier such as a semiconductor memory, a hard disk memory or an optical memory and is used to carry out the method according to one of the embodiments described above if the program product is installed on a computer or a device is also of advantage is performed.

These can each appear with the typical sentence beginning "Did you know that ..." in the display. Expenditures from the dosimeter to the display or to external services take place via a in the dosimeter 100 integrated communication module.

From the data processing unit 110 Values determined can also be sent to the server 504 for the Internet database. The database can also contain values of another user 530 , another user 532 , etc., are included. The information about the user (s) will then be transmitted through the server 504 z. B. to a health insurance 534 , a hospital 536 , a doctor 538 , a telemedicine center 540 , a social network 542 or a web platform 544 output. About the social network 542 is, for example, a player interaction 546 possible. One possible game could be: "Anyone who measures exactly X of UV intensity today has won". Since that is based on the 5 Scheme explained an information coupling between the user and z. B. his health insurance 534 allowed, for example, reward systems can be realized. So there is z. B. the possibility of a refund by the health insurance 534 after the user the info program 528 that has worked through the dangers of skin cancer here.

As already explained, takes place in the central processing unit 110 the entire evaluation, calculation and communication take place. In order to calculate an estimated individual solar time or the solar _{residual exposure} time (t _viS ), all or some of the _values are calculated on the basis of the illustration in _FIG 5 shown different parameters used and evaluated. A calculation _formula for (t _viS ) can be z. For example: t _viS = f (, W _LOC , H _müNHN , S, UVI _FC , HT _i , SC _S , LSF _i , UVSP _A , AGE _i , CLO _i , ...)

The estimated, individual solar time (t _viS ) determined from this is displayed to the user on the display z. B. the smartphone -. B. via an app - or plaster 100 self-displayed. Now the user can go to the sun. The dosimeter can be used to measure the time 100 either automatically or by a command from the user, e.g. B. via a manual, acoustic or haptic input, turn on. The automatic activation can be done, for example, when the UV sensor 230 and / or the external UV sensor 512 In response to a user's outdoor exposure, he or she perceives an abrupt increase in UV intensity, or when a geostationary location system (GPS / Galileo, etc.) estimates the location as "outdoors." As also discussed, the Sun protection factor of sunscreen can also be taken into account by the UV sensor 230 is creamed with. In this case, the sensor surface has skin-like properties, for example, is washable.

6 shows a method using a flowchart 600 for determining and / or monitoring an anticipated, individual solar time or time, respectively, on a skin of a living being until a predetermined dose of sun exposure is reached. The procedure 600 may be performed in one embodiment of the dosimeter presented herein. In one step 610 For example, a UV radiation value detected by a UV sensor of the dosimeter is read in, which represents a dose rate of UV radiation incident on the skin of the living being. The step 610 This can be done after switching on the dosimeter or switching on the dosimeter. In the embodiment shown here, the method comprises 600 a further step 620 reading in data from a geostationary location system such. B. GPS or Galileo and a step 630 the reading of additional data related to a characteristic of the skin and / or environmental conditions of the skin of the user. Optionally, the procedure 600 Steps of reading in another - in the presentation in 5 exemplified explained - have parameters. In one step 640 the estimated individual solar time (t _iSa ) is determined based on the UV radiation _value and / or a future estimated UV radiation _value and based on the data of the geostationary location system of the additional data, wherein the Sonnenresteinwirkzeit represents a time, the skin of the animal is susceptible until the predetermined sun exposure dose is reached. In one step 650 the UV radiation value is output to an external device and / or to a database. The steps 610 to 650 can be repeated as often as desired, the probable individual solar time (t _iSa ) being _{continuously recalculated} by the central processing unit during the user's stay in the sun, or at defined time intervals, so that a current individual solar time (t _iSa ) is always used Available. In this case, in an optional step besides the above-mentioned parameters but also a UV-value of a current exposure to the sun _(UV's) measured with the integrated UV-sensor and at step 640 in addition to an updated prediction (UVI _FCloc ) for a current location of the user. The corresponding formula is: t _iSa = f (t _viS , UV _is , UVI _FCloc , ...)

Thus, the user can continuously or at the end of a day or sun bath on the display, the respective time that he spent in the sun, or the remaining, recommended, expected, individual solar time and read the dose of the received UV radiation. In one step 660 the user is warned in good time before the end of the individual solar time (t _iSa ) by an output of an acoustic, haptic and / or optical signal. The user is prompted by an indication on the display, either to repeat the protective measures or to increase or to go into the shade or to take another action. In addition, the user can use the interface z. B. on the smartphone additional content, such. Recommendations, information, behaviors, tips for use, products, etc. This content is either stored on the mobile device or downloaded from the Internet. This functionality can, for. B. be realized via an app. In one step 670 A shutdown of the dosimeter or stopping a time recording of the dosimeter. The switching off or stopping can be done either automatically, z. For example, if the UV sensor senses a sudden decrease in UV intensity due to an occupant's presence in an interior space, or if the geostationary location system considers the location to be "out of doors" 670 also via a command from the user, eg. B. via an acoustic or haptic input, done.
