Abstract: Aspects of the present disclosure describe gas sensor calibration methods and subsequent sensing methods employing same in conjunction with wavelength modulation spectroscopy (WMS). Additional aspects of the present disclosure advantageously employ WMS for highly-sensitive gas concentration measurement across a range of concentrations from ambient to a high concentration environment such as fire/smoke detection. Finally, still further aspects of the present disclosure determine and then employ two calibration factors and during measurement WMS-2f spectra to determine an inflection or “turning point” and subsequently which one of the two calibration factors to employ at a given concentration.

Abstract: An integrated semiconductor heating assembly includes a semiconductor substrate, a chamber formed therein, and an exit port in fluid communication with the chamber, allowing fluid to exit the chamber in response to heating the chamber. The integrated heating assembly includes a first heating element adjacent the chamber, which can generate heat above a selected threshold and bias fluid in the chamber toward the exit port. A second heating element is positioned adjacent the exit port to generate heat above a selected threshold, facilitating movement of the fluid through the exit port away from the chamber. Addition of the second heating element reduces the amount of heat emitted per heating element and minimizes thickness of a heat absorption material toward an open end of the exit port. Since such material is expensive, this reduces the manufacturing cost and retail price of the assembly while improving efficiency and longevity thereof.

Abstract: Aspects of the present disclosure describe systems, methods and structures for determining any location on a deployed fiber cable from an optical time domain reflectometry (OTDR) curve using a movable mechanical vibration source to stimulate tiny vibration of fiber in deployed fiber cable along the cable route and a fiber sensing system at a central office to detect the vibration(s). Latitude and longitude of the location(s) of the vibration source is measured with a GPS device and a dynamic-OTDR distance is measured at central office (CO) simultaneously. The collected GPS location data and corresponding dynamic-OTDR distance data are paired and saved into a database. This saved data may be processed to graphically overlie a map thereby providing exact cable location on the map thereby providing carriers/service providers the ability to improve fiber fault location on a deployed fiber cable much faster and more accurately than presently possible using methods available in the art.

Abstract: A backlight module and a liquid crystal display device are disclosed. The backlight module comprises a backlight source, a beam splitter and a light beam conversion portion. The beam splitter converts light from the backlight source into a first and second polarization light beam. The light beam conversion portion converts the first polarization light beam into a third polarization light beam through total reflection, and outputs the second and third polarization light beam through a light exit side. Alternatively, the light beam conversion portion converts the first and second polarization light beam into a fourth and fifth polarization light beam through total reflection, and outputs the fourth and fifth polarization light beam through the light exit side. To this end, light from the backlight source is efficiently applied to irradiate a liquid crystal display panel, and the brightness of the liquid crystal display panel significantly improves.

Abstract: A space coordinate converting server and method thereof are provided. The space coordinate converting server receives a field video recorded with a 3D object from an image capturing device, and generates a point cloud model accordingly. The space coordinate converting server determines key frames of the field video, and maps the point cloud model to key images of the key frames based on rotation and translation information of the image capturing device for generating a characterized 3D coordinate set.
