Claims16
A computer executable method of increasing the accuracy of UV monitoring using a wearable UV sensing device, comprising:
- receiving UVB information that is indicative of an intensity of UVB light sensed by a UV sensor, the UV sensor disposed in the wearable UV sensing device;
- comparing the UVB information with a threshold UVB level to make a first determination if the wearable UV sensing device is indoors or outside;
- receiving secondary information indicative of light outside of the UVB range sensed by the UV sensor or a second sensor disposed in the wearable UV sensing device;
- using the secondary information to make a second determination about the environment of the wearable UV sensing device;
- using the second determination about the environment to select one of a plurality of environment models for predicting the UV Index;
- predicting the UV Index with the selected model;
- and
- visually presenting UV index information to the user on a user device, the UV index information indicative of the predicted UV index.
A computer executable method of estimating UVA and UVB with a UVI sensor disposed in a wearable UV sensing device, comprising:
- receiving as input, from a remote user device, a solar zenith angle;
- calculating a ratio comprising UVB and UVA using the solar zenith angle;
- receiving as input UVI information that is indicative of an output signal of a UVI sensor disposed in the wearable UV sensing device;
- calculating an estimated UVB using the UVI information and the calculated ratio comprising UVB and UVA;
- and
- calculating an estimated UVA using the UVI information and the calculated ratio comprising UVB and UVA;
- and
- estimating a UV index using the estimated UVB and the estimated UVA;
- and
- visually presenting UV index information to the user on a user device, the UV index information indicative of the estimated UV index.
A computer executable method of modifying sensed UV signals based on orientation of a wearable UV sensing device, comprising:
- receiving as input UV information indicative of UV light sensed by a UV sensor disposed in the wearable UV sensing device;
- and
- estimating a UV irradiance incident normal to a face of a subject using an angle of tilt of the wearable UV sensing device relative to a transverse plane of a subject, and the UV information, the angle of tilt derived from orientation sensor information from an orientation sensor disposed in the wearable UV sensing device and
- using the estimated UV irradiance in estimating a UV dose, and visually presenting on a user device to a user information indicative of the estimated UV dose.
