Abstract:
In one embodiment, a radiation based analysis system comprises a first radiation source to generate first radiation having a wavelength outside the visible spectrum, a second radiation source to generate second radiation having a wavelength within the visible spectrum, and a waveguide coupler to couple a portion of the first radiation and a portion of the second radiation into a combined radiation beam such that the first radiation and the second radiation follow a path that is substantially coaxial.
Abstract:
An ice level sensing system for an appliance having a cavity with a cavity wall. An ice storage bin and an ice maker are disposed within the cavity. The ice storage bin is configured to hold ice discharged from the ice maker. The ice level sensing system includes a transmitter for transmitting a light beam and a detector for detecting the light beam. The transmitter and the detector are disposed on the cavity wall. A reflector is disposed relatively remote from the transmitter. The transmitter is operative to project the light beam toward the reflector. The transmitter and the detector are angled relative to each other so that the light beam reflected by the reflector is directed toward the detector.
Abstract:
An optical sensing module is adapted to be assembled to a frame of a display device. The display device comprises a display module and the frame, and the display module has a display area and the frame surrounds the display area. The optical sensing module comprises a casing and an optical sensor. The casing is pivoted to the frame and the optical sensor is configured in the casing for sensing external light projecting on a side of the casing. The optical sensor is capable of sensing a brightness of the display area when the side of the casing faces the display area and sensing a brightness of an ambient light when the side of the casing doesn't face the display area.
Abstract:
A Solar Access Measurement Device (“SAMD”) located at a predetermined position is disclosed. The SAMD may include a skyline detector enabled to detect a skyline of a horizon relative to the SAMD, an orientation determination unit enabled to determine the orientation of the skyline detector, and a processor in signal communication with the skyline detector and orientation determination unit.
Abstract:
An optical emission spectroscopic (OES) instrument includes a spectrometer, a processor and an adjustable mask controlled by the processor. The adjustable mask defines a portion of an analytical gap imaged by the spectrometer. The instrument automatically adjusts the size and position of an opening in the mask, so the spectrometer images an optimal portion of plasma formed in the analytical gap, thereby improving signal and noise characteristics of the instrument, without requiring tedious and time-consuming manual adjustment of the mask during manufacture or use.
Abstract:
Disclosed herein is a method and apparatus for measuring partial discharge using a UV sensor array. The apparatus includes a UV sensor array including plural sensors detecting UV rays from an analyzing target of a power facility at a location separated a predetermined distance from the target and converting the UV rays into discharge current, an image measurement unit measuring the distance between the sensor array and the target and supplying an actual image of the target, a UV intensity detection unit measuring intensity of the discharge current converted from the UV rays detected by the sensor array, and a UV location detection unit analyzing and outputting a UV emitting location obtained by matching the discharge current intensity measured by the UV intensity detection unit to combined data of the actual image of the target supplied from the image measurement unit and sensor locations of the sensor array.

The exposure module can determine exposure to an environmental element based at least on the local conditions sensed by the sensor and the local environmental conditions obtained by the network interface.
Abstract:
A light measuring device is disclosed which can take in light from different portions of a plane light source efficiently to carry out measurement. The light measuring device for measuring light from a plane light source includes a spatial division device configured to carry out operation for successively taking in light from different portions of the plane light source. An optical condensing device condenses the light from the different portions of the plane light source taken in by the operation of the spatial division device. A detector receives the light condensed by the optical condensing device and outputs a signal corresponding to the received light.
