Abstract: A method and apparatus for actively aligning an optical device are described. An apparatus includes an optical device. The optical device includes a supporting surface, a light source mounted to the supporting surface, a lens mount configured to hold a lens, a lens holder configured to hold the lens mount, wherein the lens mount is configured to be mounted to the supporting surface. A light detector is configured to determine a light intensity of a light beam through the lens, the light intensity indicating the alignment of the lens. An alignment device is to move the lens until the light intensity indicates that the lens is aligned, and a curing light is to cure adhesive layers between the lens and the lens mount, the lens mount and the lens holder, and the lens holder and the supporting surface.

Abstract: An optical sensing circuit includes a first, a second, and a third optical sensing element and a sampling circuit. The first sensing element provides a first current from a first node to a second node according to an ambient light and a sensing signal. The second optical sensing element drains a second current from the second node to the first node according to the ambient light and the sensing signal. The third optical sensing element is coupled between the first node and the second node. The third optical sensing element receives a first color light, and transmits the first current to the second node or transmits the second current to the first node according to the first color light. The sampling circuit is turned on according to the sampling signal to output a detection signal based on the voltage level of the second node.

Abstract: A UV exposure dosimetry system includes at least one UV sensor that 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 system integrates the extrapolated UV intensity data over time to calculate real-time UV dosage and vitamin D production by taking into account factors including 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 is also adapted to measure sun exposure time based on the corrected UV intensity over a period of time. The UV dosimetry system supports multi-user control through an advanced and user friendly input and output interface.

Abstract: A sensor assembly, comprising a housing having a receiving window covered by an optically transparent cover. The housing accommodates electric components, at least comprising a motion sensor and an ambient light sensor. The motion sensor and the ambient light sensor are positioned such that light entering the cover impinges on the motion sensor and the ambient light sensor. Between the cover and the ambient light sensor is an optical diffuser positioned, such that light entering the cover traverses the optical diffuser before impinging on the ambient light sensor. The sensor assembly may be used separately or incorporated in an electric or electronic device.
