Description

A Low Power System and Device for Detecting UV Radiation TECHNICAL FIELD The t disclosure relates to a system and device for detecting and/or monitoring solar or UV radiation. More ularly, the present disclosure may relate to a portable low power system and device for detecting ultraviolet (UV) radiation which is adapted to communicate with a server.

BACKGROUND The number of skin cancer and other sun related aliments have been increasing over the last several decades. With increasing populations the incidence of skin cancer cases will only se without tative es. High levels ofUV radiation related medical exposure may cause an increased possibility for a person to develop UV issue, such as skin cancer.

The Fitzpatrick scale was developed as a numerical classiﬁcation schema for human skin colour as a way to classify the l response of skin to iolet (UV) light. This scale may be used to determine weather conditions are safe for a person to have a prolonged exposure to the sun or other UV light sources.

Some known devices use an array of ﬁxed or permanent UV detectors over a predetermined area which detect UV radiation over a gridded area. However, these devices cannot predict an individual’s personal exposure ofUV radiation and require a signiﬁcant amount of energy to e. These devices generally have a ﬁxed number of sensors and may only collect information from a predetermined location. Therefore, these devices or systems may have a cant number of data collection blackspots or gaps, which may result in an incorrect data set. Previous systems have been large or bulky.

While some portable devices for detecting radiation are known, these devices are generally some, expensive and are not discretely used. These devices are not generally suitable to be carried by a user comfortably or discretely and therefore users are less inclined to use such a device. Further, these devices also require a signiﬁcant amount r to function and require constant recharging or frequent replacement of batteries to effectively e.

Further, these devices usually require a large number of features such as an inbuilt screen, GPS or oning hardware, buttons and other features which may cally increase the manufacturing costs and are generally not intended to be able.

As such, there may be a need for a low power energy usage or high energy efﬁciency and low cost device which may log or record UV radiation exposure.

Any discussion of the prior art throughout the speciﬁcation should in no way be considered as an ion that such prior art is widely known or forms part of common general knowledge in the ﬁeld.

DESCRIPTION OF THE INVENTION Preferred ments of the present sure will now be described with reference to the accompanying drawings and non—limiting examples.

In a ﬁrst embodiment of the present disclosure, there may be provided a device or system 100 adapted to detect and store ultraviolet (UV) radiation data. The UV data may be at least one ofUV irradiance or UV spectral irradiance. The data collected may be manipulated, factored or augmented to display a predicted UV exposure level or a UV risk level to a user or any other predetermined data set. For example, if a person has skin type—I they may have a UV factor of 0.9, while a person with skin I may have a UV factor of 0.75. It will be appreciated that any predetermined factors may be used to provide a UV exposure level, UV risk or UV index. Throughout this speciﬁcation, the term “UV radiation” may refer to a UV radiation irradiance and/or UV al irradiance. While the system of the present sure is preferably adapted to use the Fitzpatrick scale for skin classification, it will be appreciated that a custom scale may also be used.

Referring to the embodiment illustrated in Figure l, the system 100 comprises a first device 110 and a second device 110A in which the second device 110A may optionally be in communication with a server 195. The first device 110 being configured to detect UV ion and convert the UV radiation into UV radiation data. The data may correspond to a predetermined threshold, intensity or UV radiation irradiance level.

The first device 110 and second device 110A may then be configured to synchronise With each other such that the UV radiation data may then be communicated or transmitted from the ﬁrst device 110 to the second device 110A. After the second device 110A receives the UV radiation data, the second device 110A may associate the UV radiation data with a user account and upload the data to a server 195. The server 195 may then assess, analyse or augment the data such that the data may be used to generate at least one data set, such as a heat map, a radiation map, UV exposure data or any other data associated with the stored UV radiation. At least a p01tion of the generated data set may be displayed on a display device, for example, a display of the second device or an internet browser.

In at least one embodiment, the ﬁrst device 110 is d to detect and store radiation data, preferably UV radiation data. The ﬁrst device 110 may be adapted to detect at least one ofUVA, UVB and UVC radiation. More preferably, the ﬁrst device 110 detects both ofUVA and UVB radiation. It will be iated that the ﬁrst device 110 may also be adapted to detect other forms of radiation. As illustrated in the Figures, the ﬁrst device 110 comprises a ﬁrst shell 115 which encapsulates or houses a micro- controller unit (MCU) 120, at least one radiation sensor 130, a power source 140, storage medium 150, and an antenna 160. The MCU 120 may be used to convert the received UV ion into UV ion data and store the UV radiation data in a storage medium 150. The MCU 120 may r be conﬁgured such that it may receive data, commands or protocols from the second device 110A.

The storage medium 150 may be for example, a ﬂash memory, EEPROM or any other non—volatile storage medium. Preferably, the storage capacity of the ﬁrst device 110 is between 128KB to 1MB and more preferably is about 256KB. However, it will be appreciated that the internal memory of the ﬁrst device 110 may be any predetermined size sufﬁcient to record data.

Optionally, the ﬁrst device 110 further comprises an accelerometer 170. The accelerometer 170 may be used to activate or deactivate at least one sensor 130 if there is no movement for a predetermined period of time. The accelerometer 170 may be red to detect whether the ﬁrst device 110 is falling and arily stop recording data if a fall is detected. The accelerometer 170 may correlate movement data with UV radiation data to determine optimal UV ion for activities or sports. Preferably, the accelerometer 170 may detect Whether a person is intentionally sunbathing or exposing themselves to high levels ofUV radiation.

Preferably, the ﬁrst device 110 further comprises a communication module, such as a transceiver or a low power protocol (not shown), which may be adapted to send and/or receive data which has been stored in the storage medium 150. In at least one embodiment, the communication module is integral to the MCU 120. The UV radiation data may be sent to a second device 110A adapted to communicate with the ﬁrst device 110 such that the second device 110A may perform at least one of a classiﬁcation, interpretation, manipulation, augmentation or otherwise correlate stored data. The stored data may be associated with at least one other data set or manipulated by a predetermined thm or equation. The low power protocol of the ﬁrst device 110 may e a reduced amount of power in comparison with which may improve the efﬁciency of the device and may reduce power consumption. A low power protocol may be, for example, a BluetoothTM Low Energy (BLE) or any other suitable low power wireless personal area k. A BLE module may be included in the ﬁrst device 110 and may be formed as part of the MCU 120.

In a further embodiment, the second device 110A uploads the UV radiation data to a cloud or server 195 which may perform at least one of a classiﬁcation, interpretation, manipulation, augmentation or correlation of stored UV ion data.

The second device 110A may a portable device, such as a tablet computer, a laptop, smartphone, mobile/cellular phone or any other electronic device which is capable of determining the relative position of the second device 110A. Preferably, the second device 110A comprises a second shell 115A comprising at least one of a display 180, a GPS 190, communication module, an antenna 160A and an associated storage medium 150A, such as a ﬂash drive, hard drive, EEPROM, state drive (S SD) or any other suitable non—volatile memory. The second device is preferably adapted to have internet or wiﬁ connectivity such that data may be uploaded to a server 195 or cloud. [003 6] In at least one embodiment, the second device 110A may display a user t of a user on the display 180. The second device 110A may be adapted to display data associated with a user account or a public t to a user for a particular time period such that a user may see potential UV ion exposures or other predetermined or preselected data. Other preselected data may include, for example, a UV radiation map, a heat map, common exposure levels, anticipated exposure levels, times periods to avoid a particular location, suggested preventative measures for reducing UV ion exposure, or any other predetermined data or predetermined e.

In a further embodiment, the ﬁrst device 110 is conﬁgured such that after the second device 110A receives the stored data, the data stored on the ﬁrst device 110 is deleted or otherwise may be itten. This may allow the ﬁrst device 110 to continue to record UV radiation data and ensure that there is sufﬁcient internal storage ing to record latest UV exposure levels. Optionally, if the internal storage has been expended with data and the device has not uploaded the data, the ﬁrst device 110 may selectively delete the oldest data set or may delete the lowest value data sets such that only the highest UV exposure data sets remain.

Referring to Figure 2, there is provided an embodiment of a process ﬂow chart 200 of the present disclosure. The ﬁrst device 110 of the system 100 senses the UV radiation 210 and converts the sensed UV ion 220 into UV radiation data. The converted UV radiation data is then stored in the memory 150 of the ﬁrst device 110.

Preferably, the second device 110A does not store data long term but is conﬁgured to relay at least a n of data to a server 195 or cloud for long term storage. The user may View or extract data from the server 195 using an internet browser or application which may be associated with the second device or a third device, such as a computer or laptop. The ﬁrst device 110 may be conﬁgured to communicate with the second device 110A such that the ﬁrst device 110 may upload or transmit the stored UV data to the second device 110A. The second device 110A is preferably conﬁgured to upload the stored UV radiation data 250 to a server 260. Preferably, the second device 110A associates at least one coordinate location with the data and uploads the coordinate data to the server 195.

Figure 3 s an embodiment of the ﬁrst device 110, which ses a ﬁrst side 310 and a second side 320. The ﬁrst side 310 and second side 320 of the ﬁrst device 110 is illustrated with the at least one radiation sensor 130 positioned near to one end of the ﬁrst device 110 such that the at least one sensor may detect radiation levels if either of the ﬁrst side 310 and/or the second side 320 is facing the wearer or user. Preferably the sensor 130 is protected by, or housed in, a casing integrally formed or ﬂuidly sealed with the ﬁrst shell 115. This sensor 130 conﬁguration may allow for a more continuous and effective recording ofUV radiation data.

Figure 4 depicts yet r embodiment of the ﬁrst device 110. The ﬁrst device 110 comprises a ﬁrst side 410 and a second side 420, in which the ﬁrst side 410 has at least one UV sensor 130 which is with a protective case 430 ally formed with the ﬁrst shell 115 and the second side 420 has a able securing means 440. The releasable securing means 440 may be, for example, a clip, pin, key-ring, link or other suitable fastener such that the ﬁrst shell may be removably ed to an item of clothing, such as a shirt or bikini. The ng means 440 may be disposed on a side of the ﬁrst shell 115, such as the top surface or the rear surface of the ﬁrst shell 115. It will be appreciated that the device may be formed With a ﬂuid resistant or ﬂuid tight shell.

Optionally, the ﬁrst device 110 comprises a status indicator (not shown) such as a light, which may indicate to a user that the device has a low battery, is synchronising or has any other predetermined status. The light is ably an LED or other low energy consumption status indicator.

In yet another embodiment, the ﬁrst device 110 preferably takes an sample or re reading at a predetermined or random interval and records the UV radiation reading. As such, the ﬁrst device 110 may be adapted to differentially change a sampling interval for detecting UV radiation based on the time of day. For example, the predetermined interval may be every 10 (ten) seconds, or any other predetermined time.

In another example, the ﬁrst device 110 associates the relative time with a predetermined recording period. For example, if the time is between 6AM to 8PM, the ﬁrst device 110 takes an exposure reading every 10 (ten) seconds, and between 8PM to 6AM, the ﬁrst device 110 takes an exposure reading every 20 y) seconds due to the likelihood of reduced radiation exposure. It will be appreciated that any ermined or random time recording period may be conﬁgured for use by the ﬁrst device 110.

In yet a further embodiment, the second device 110A may allow a user to adjust the predetermined interval between upper and lower thresholds. For example, a user may assign a 5 (ﬁve) second interval to be used during 6AM and 8PM and a 25 y—ﬁve) second interval between 8PM and 6AM. In one example, the periodic increment may be several hours such that during a ermined time period the at least one UV sensor 130 may be temporarily deactivated to reduce battery consumption. Other time periods may also be ed by the user, or may be updated by the system 100 when the ﬁrst device 110 synchronises with the second device 110A.

Preferably, the ﬁrst device 110 may record and store at least 10 (ten) days ofUV ion data without onising with the second device 110A. More preferably, the ﬁrst device 110 can store 100 (one hundred) days of data without synchronising with the second device 110A.

A ﬁrst device 110 preferably comprises a unique ID or may be assigned a unique ID by the system. The unique ID may be associated with a user ID such that a user may view personal data collected. The user ID may be associated with at least one identiﬁer stored and collates personal ID data with the server 195, such as skin type classiﬁcation, a user name, a real name, working address, home address, commonly visited locations, age, sex, hair colour or any other predetermined personal information. The information associated with the user ID may be used to trigger at least one alert or message toa user, via at least one of the ﬁrst device 110 or more preferably the second device 1 10A. An alert may be at least one of a sound, a vibration, a message, a light indicator or any other predetermined signal. For example, if a type—I skin type classiﬁcation is assigned to a user ID and there is a high possibility for the user to be exposed to a signiﬁcant amount ofUV radiation, the system 100 may issue an alert or message to a user to stay s or out of direct light such that the user may limit the potential exposure to the ially harmful UV radiation.

In at least one embodiment, the user ID and the unique ID are hashed, encrypted or otherwise anonymised such that the user ID and the unique ID cannot be accessed by a user of a system. This may improve the security of the system, such that a single user ID cannot be identiﬁed by a user of an overarching system.

The data uploaded to the server 195 by the second device 110A may be used to generate a heat map or radiation map. A heat or radiation map may be a graphical representation of the UV data on a location map, in which the location map may be an arbitrary map or a geographical map. A predetermined colour may depict a higher intensity or range ofUV data values on a map. Preferably, the more solid or intense a colour on the map appears represents a relatively higher risk or higher levels ofUV radiation. Alternatively the scale of relatively higher risk or higher levels ofUV ion may be colour coded with reference to a legend on the map. The heat map may have a scale for visually determining This map may be used for, for example, scientiﬁc research, predicting future ion hot spots or used for alerting users of the system in a particular area to avoid unnecessary exposure to the radiation. This may reduce the time a user spends being d and therefore may reduce the potential of a UV ion related injury or effect ing, such as damaging skin cells which may cause skin cancer or melanomas to form.

In at least one embodiment, the ﬁrst shell is preferably formed with a ﬂuid tight seal, such as a water tight seal. This is advantageous as this may allow a user to expose or submerge the ﬁrst device 110 in a liquid and still record UV exposure. This may provide a more accurate indication of the actual UV exposure of a user if worn into a body of water and may allow a user to wear the device into wet outdoor ions.

In yet another embodiment, the first device 110 may be passively active, such that when not in use or not assigned to a user the ﬁrst device 110 consumes less power than when in use. In one example, the UV sensor 130 is covered and preferably does not record radiation levels until after the cover (not shown) is removed from the sensor 130.

Preferably, the cover may reﬂect or prohibit UV radiation from ting the UV sensor 130, such that upon removal of the cover the UV sensor 130 the initial UV exposure activates the UV sensor 130. In another example, once a user associates a unique ID of the device with a user ID, the ﬁrst device 110 may be conﬁgured to start recording UV radiation. In a further example, the ﬁrst device 110 is ted only after removal a predetermined action, for example when removed from an associated packaging.

The system 100 of the present disclosure may also issue an alert to a user based on predictive location. For example, if the system 100 has at least one previous log of a user with associated on data, the system 100 may predict whether a person will be in a particular location at a particular time. Therefore, even if a user of the system 100 has not synced the ﬁrst device 110 with the second device 110A, the system may issue an alert based on at least one previous log.

In yet another embodiment, the ﬁrst device 110 may include a rechargeable power source or allow access to the power source 140 such that the power source may be replacable. The rechargeable battery may be inductively recharged by a user of the system, such that the ﬁrst device 110 may be reused. In yet a further embodiment, the ﬁrst device 1 10 may comprise an AppleTM security chip (not shown) or other M chip which may allow communication to AppleTM devices.

In a further embodiment, the ﬁrst shell 115 of at least one of the ﬁrst device 110 is textured (not shown) to improve the gripability of the device. Preferably, a predetermined logo or decal (not shown) may be ed on the casing such that a device may be customised by a user.

Preferably, the second device 110A may log location data with ated time, otherwise referred to as a location log, and the ﬁrst device 110 may store UV data with a time stamp. This may allow the system 100 to more tely associate the logged location data and UV data relative to a user. As the second device 110A is ably a mobile phone, such as a smart phone, the second device is likely to have been to the same locations as the user of the ﬁrst device 110. As such, the user may be provided with the option to associate a location log with the UV data after the ﬁrst device communicates the UV data to the second device. This may allow for an association ofUV data and location data with respect to time. Optionally, the user may associate selected portions of the location log with the UV data.

In yet another embodiment, a ﬁrst user ﬁrst device 110 may be adapted to communicate with a second user ﬁrst device 110 such that the ﬁrst user ﬁrst device 110 If the ﬁrst user may it at least a portion of data to the second user ﬁrst device 110. ﬁrst device 110 communicates data to second user ﬁrst device 110, the ﬁrst user device that when the may associate an ID or other identiﬁer with the communicated data, such second user ﬁrst device 110 uploads data to the second device 110A two sets of independent data may be identiﬁed by the second device 110A.

In yet a further embodiment, the ﬁrst device 110 may be adapted to communicate data to the second device 110A if the ﬁrst device is a close proximity to the second device 110A. For example, if the ﬁrst device is 110 within approximately 1 meter from the second device 110A. It will be appreciated that any predetermined proximity distance may also be used.

In another embodiment, the ﬁrst device 110 may optionally comprise a switch (not shown), such as a button, a toggle or any other two state means. The switch may be conﬁgurable to be in an active on or an inactive on, such that when the switch is in the active position the ication module the ﬁrst device 110 is active and may be adapted to communicate with the second device 110A. When the switch is in an inactive position the communication module is inactive and may reduce the overall power consumption of the ﬁrst device 110.

In a further ment, the communication module of the ﬁrst device 110 may be conﬁgurable to be in an inactive state and an te state. Preferably, the ﬁrst device 110 is in an inactive state in which the communication module is inactive. The communication module ﬁrst device 110 may be conﬁgured to be in the active state by shaking or vigorously moving the ﬁrst device 110. Optionally, the accelerometer may be adapted to detect shaking or movement of the device to activate the communication module. Alternatively, the ﬁrst device 110 may r comprise a gyroscope or sensor (not shown) which may be adapted to detect shaking or vigorous movement of the ﬁrst device 110. If the ﬁrst device 110 is in communication with a second device 110A the communication module Will remain active until either a user has disconnected the tion, which is preferably a Wireless connection, or the connection between the ﬁrst device 110 and the second device is lost 110A, for example if the ﬁrst device 110 is a not within a ermined radius of the second device 110A. If the device 110 is not in communication with a second device 1 10A, the communication module may turn off or return to an inactive state after a predetermined amount of time, such that power consumption of the ﬁrst device 110 is reduced. [005 8] In yet a further embodiment, the ﬁrst device 110 may automatically connect with any second device 1 10A with an appropriate application which is in close proximity to the ﬁrst device. This may allow for more “real—time” or more current UV data to be ed to the server 195 or cloud, such that ifUV radiation is detected to be relatively high or unsafe a warning may be issued to users. [005 9] In a further ment, the radiation sensor may be 130 adapted to detect any predetermined electromagnetic waves. ally, the device comprises multiple sensors to detect multiple forms of radiation, or may have more than one sensor orientated at different , relative to one another. Disposing sensors at different angles may assist with determining a more true reading of radiation exposure of a user.

Referring to Figure 4, there is illustrated a r embodiment of the internal components 500 of the ﬁrst device 110. The radiation sensor 130 is positioned at an angle relative to the printed circuit board (PCB) of the ﬁrst device 110. In an alternative embodiment, the radiation sensor 130 is positioned at an angle relative to a source of radiation, for example the sun. ably, the angle of the radiation sensor 130 to either the source of radiation and/or the PCB is between 30 to 60 degrees, and more preferably between around 40 to 50 degrees, and even more ably is around 45 degrees. It will be appreciated that the angle of the sensors may also be relative to the protective case (see Figures 3 and 4). Disposing the sensor at an angle which is not parallel or perpendicular to the body may assist with capturing electromagnetic radiation and therefore may be adapted to provide more accurate detection of radiation. Mounting the sensor at an angle may be of particular advantage, for example, when a device is worn on the wrist of a user. The internal components of the device preferably include a power source 140, a microprocessor (also referred to as a micro-controller unit 120) and at least one transmitter (or more preferably a transceiver).

Preferably, the ion sensor 130 angle relative to the source of radiation is such that regardless of which position the device is orientated, the device will be adapted to detect ion from the source of radiation. ably, the relative angle between the source of radiation and the radiation sensor 130 can be determined by the ﬁrst device such that the calculation of radiation exposure can be ed, modiﬁed or otherwise d to reﬂect a more accurate radiation exposure.

Preferably, the ﬁrst device 110 is adapted to be worn on a user’s wrist or on an item of clothing. The radiation sensor 130 may also be adapted to be attached to other devices, such as a mobile phone case or the like. This may allow a user to only have the device active While they are in a source of radiation they Wish to monitor, such as at the beach.

In yet another embodiment, at least the ﬁrst device 110 may be disposed in an item of clothing, for example; a swim suit or a hat. Disposing the device in an item of clothing may assist with a user taking the ﬁrst device 110 when outside or in a radiation exposure location. The item of clothing may have a pocket or the like which allows ing or releasable retainment of the first device 110 in the item of clothing.

Alternatively, a clip and/or tether may be attached to an item of clothing and the ﬁrst device. The tether may be similar to that of a paciﬁer style tether. A clip for example may be a ner clip, a D—clip, a C—clip, a sling loaded clip, a spring hook or the like. atively, the first device may be integrally formed or disposed in an item of clothing such that it cannot be removed. For example, this may be useful for en’s hats, prisoner clothing, swim wear, ofﬁcial uniforms or any other predetermined article of clothing.

The angle of the device may then be factored with respect to input received from a gyroscope, inclinometer, accelerometer, GPS or any other suitable tilt sensor. A tilt UV —16— index may then calculate the actual radiation being received based on a tilt compensated UV index calculation. The UV index ation may be based on an assumption that the ﬁrst device 110 has the radiation sensor 130 facing generally upward (relative to the ground). This allows the ﬁrst device 110 to generate a more accurate reading of radiation exposure for a user of the ﬁrst device 110. Preferably, the device comprises at least one accelerometer adapted to determine the orientation of the device.

In yet another embodiment, the device may be adapted to detect where a source of radiation is relative to the . Knowing the orientation of the ﬁrst device 110 relative to a source of radiation may further allow for the UV index calculation to be further modiﬁed compensating for the angle of the radiation source relative to the ﬁrst device 110.

In yet a further embodiment, an estimation of radiation exposure may be generated by ing ambient light and a reported real time or periodically updated radiation index, such as a UV index. The device may further comprise an ambient light sensor which may be adapted to continuously detect light in the visible um (Visible to a human) or other predetermined omagnetic waves. Detecting the light may allow the device to alter the estimation of the radiation exposure. For example, lower light levels may indicate that a wearer is in the shade or indoors, rather than outdoors.

Preferably, the server records and stores data related to radiation levels, such as a UV radiation index which may be generated by meteorology ns. Using the detected UV index to generate a UV exposure allows a user to obtain a reading of the radiation exposure when the ﬁrst device 110 is synchronised with the server, Via the second device 110A. The data relating to the location of the user and the UV index may then be matched and can provide r source of estimation for UV re of a user.

In yet a further embodiment, the radiation sensor may be a silicon based (Si— based) photodetector. The Si—based photo detector may rely on n—p type nductors technology, such as n—p type homojunction semiconductors technology. Other nductor technology may also be used, such as um dioxide (TiOZ) or zinc oxide (ZnO). ally, ZnO nanopaiticles on low—cost substrates, such as glass, may be used to detect UV radiation. The radiation sensor 130 may comprise semiconductor particles ed as beads or dots on the surface which may assist with detection of radiation levels. It will be iated that any radiation sensor 130 may be used with the ﬁrst device 110 of the present disclosure.

Although the disclosure has been described with reference to speciﬁc examples, it will be appreciated by those skilled in the art that the disclosure may be embodied in disclosure many other forms, in keeping with the broad principles and the spirit of the bed herein.

The present disclosure and the described preferred embodiments speciﬁcally include at least one feature that is industrial applicable.
