Abstract

A system is provided for determining personal ultra-violet (UV) radiation measurements. The system may include a measurement device configured to measure UV irradiation; and a terminal device configured to receive an output of the measured UV irradiation from the measurement device and to display a specific user's personal UV exposure risk level based on at least the measured sun irradiation.

First claim

What is claimed is:

1. A device configured to measure ultra-violet (UV) radiation exposure, comprising:
an electronic element configured to detect UV radiation exposure;
circuitry configured to transmit detected UV radiation exposure to an external device;
an antenna that is at least 9.4 mm; and
a clip that is made of a metallic material that is in a form of a closed loop that is folded over on itself,
wherein a read range between the device and a terminal device configured to receive an output of the measured UV irradiation from the measurement device is at least 10 mm.

2. The device according to claim 1 , wherein the electronic element is a UV sensitive LED.

3. The device according to claim 2 , wherein the circuitry includes a near field communication device.

4. The device according to claim 1 , further comprising a flexible material which encapsulates the electronic element and the circuitry.

5. The device according to claim 1 , wherein the device is configured to attach to a user's fingernail.

6. The device according to claim 1 , wherein the circuitry is configured to transmit the detected UV radiation exposure to the external device at regular intervals.

7. The device according to claim 1 , wherein the circuitry is configured to transmit the detected UV radiation exposure to the external device at upon request from the external device.

8. A system for determining personal ultra-violet (UV) radiation measurements, comprising:
a measurement device configured to measure UV irradiation at one of a plurality of predetermined locations on a user; and
a terminal device configured to receive an output of the measured UV irradiation from the measurement device and to display a specific user's personal UV exposure risk level based on at least the measured sun irradiation,
wherein the terminal device is configured to apply a correction factor, from a plurality of predetermined correction factors corresponding respectively to the plurality of predetermined locations on the user, to the measured UV irradiation based on the location of the measurement device on the user.

9. The system according to claim 8 , wherein the terminal device is configured to receive the measured UV irradiation from the measurement device at regular intervals over a predetermined time period, and display the specific user's personal UV exposure risk level based the measured sun irradiation taken over the entire predetermined time period.

10. The system according to claim 9 , wherein the terminal device is configured to correlate information related to specific user activities over the predetermined time period to the measured sun irradiation received from the measurement device.

11. The system according to claim 1 , wherein the terminal device is configured to correlate information of a skin type of the user and the measured UV irradiation received from the measurement device.

12. The system according to claim 1 , wherein the terminal device is configured to output a recommended method of protection or action based on the measured UV irradiation received from the measurement device.

13. A method, implemented by a system for determining personal ultra-violet (UV) radiation measurements, comprising:
measuring, with a measurement device, UV irradiation at one of a plurality of predetermined locations on a user; and
receiving, by a terminal device, an output of the measured UV irradiation from the measurement device and displaying a specific user's personal UV exposure risk level based on at least the measured sun irradiation,
wherein the terminal device is configured to apply a correction factor, from a plurality of predetermined correction factors corresponding respectively to the plurality of predetermined locations on the user, to the measured UV irradiation based on the location of the measurement device on the user.

14. The system according to claim 8 , wherein UVA and UVB exposure is calculated based on the measured UV irradiation, and the UVB exposure calculated using a pre-computed lookup table that provides a conversion factor as a function of an amount of ozone in the atmosphere and a solar zenith angle (SZA), the SZA being determined based on a detected global positioning system (GPS) location and time.
