Abstract:
A UV exposure dosimetry system includes at least one UV sensor that accurately measures the UV irradiance intensity. The UV dosimetry system integrates the measured UV irradiance intensity over time to calculate the real-time UV dosage and the vitamin D production by taking into account factors comprising UV sensor location, body surface area, clothing coverage, and sunscreen usage. Based on the measurement, the system can predict the time remaining to skin burn and the time remaining to reach daily goal of vitamin D production. The system can also provide feedback to the user of the device based on a composite metric assessing the degree of balance between the risk of UV exposure and the benefit of UV exposure. The UV dosimetry system supports multi-user control through an advanced and user friendly input and output interface.

Abstract:
A UV exposure dosimetry system includes at least one UV sensor that accurately measures the UV irradiance intensity. The system can generate extrapolated UV intensity data based on measured UV intensity data to correct unreliable UV measurement due to inconsistent irradiation of UV light. The UV dosimetry system integrates the extrapolated UV intensity data over time to calculate the real-time UV dosage and the vitamin D production by taking into account factors comprising UV sensor location, body surface area, clothing coverage, and sunscreen usage. Based on the measurement, the system can predict the time remaining to skin burn and the time remaining to reach daily goal of vitamin D production. The UV dosimetry system supports multi-user control through an advanced and user friendly input and output interface.
Abstract:
A sensing device with a glare shield has an infrared sensor and a glare shield. The infrared sensor has a body and a lens hood. The lens hood is mounted around an outer periphery of the body. The glare shield is conical, is detachably mounted around the lens hood of the infrared sensor, and extends in a direction away from the body of the infrared sensor. The glare shield prevents the infrared sensor from being affected by glare emitted from adjacent lighting devices. Accordingly, the sensing device avoids incorrect judgment of environmental luminance caused by lighting devices nearby and therefore generates less misoperation, so that the goal of being more power-saving can be achieved.
