Abstract:
An optical sensing module includes a substrate, a cover, a plurality of light-emitting chips, a light-receiving chip, and a plurality of encapsulants. The cover is disposed on the substrate. A plurality of first chambers and a second chamber are formed between the cover and the substrate. The cover has a plurality of light-emitting holes communicating with the first chambers, respectively, and a light-receiving hole communicating with the second chamber. The light-emitting chips are disposed on the substrate and in the first chambers, respectively. The light-receiving chip is disposed on the substrate and in the second chamber. The encapsulants fill the first and second chambers and enclose the light-emitting chips and the light-receiving chip, respectively. Hence, characterized in that: the light-emitting chips and the light-receiving chip are disposed on the substrate, and the light-emitting chips emit light beams in different colors to enhance light emission efficiency.

Provided herein are a wearable radiation detector and a method of controlling thereof, the detector including: the radiation collection unit operable to collect light and output a signal corresponding to the light collected; a memory; a display unit; a processor operable to receive the signal output by the radiation collection unit, to store a value in the memory corresponding to the signal output by the radiation collection unit, to output an output signal based at least on the signal corresponding to the light collected by the radiation collection unit and to control the display unit to display an indication corresponding to the output signal, wherein the determining includes continually calculating the maximum exposure level based on the light being received by the radiation collection unit.
Abstract:
A method is provided for operating an electronic device. The method includes detecting an ultraviolet ray value through an ultraviolet ray detection sensor; acquiring an image including a sun object; comparing a position of the sun object within the acquired image to a position of a guide object; and correcting the detected ultraviolet ray value based on a difference between the position of the sun object and the position of the guide object
Abstract:
Method, product and blocking element of short wavelengths in LED-type light sources consisting of a substrate with a pigment distributed on its surface and, in that said pigment has an optical density such that it allows the selective absorption of short wavelengths between 380 nm and 500 nm in a range between 1 and 99%.
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 also calculates the UV index in real-time, and can crowd source the measured data in a network. The UV dosimetry system supports multi-user control through an advanced and user friendly input and output interface.
Abstract:
A system and method for characterizing the power and luminance values for a display. This may include testing a device to determine a luminance value for a display of a given device at a given current and determining whether the first current is to be adjusted during future uses based on a comparison of the luminance with at least one threshold value. This may also include storing an adjusted current value if it is determined that the first current is to be adjusted.
