Abstract: A calibration device according to embodiments of the disclosure is capable of being used with a non-invasive sensor. Certain embodiments of the calibration device simulate a human pulse by varying the volume of blood being measured by the optical sensor. Further, embodiments of the calibration device allow the generation of calibration curves or data for measured parameters over larger ranges of measured values compared to patient-based calibration.

Abstract: An optical device is capable of controlling a projector, wherein the projector is capable of wirelessly receiving an image signal from a data source, combining an identification signal into the image signal to generate a projection signal, and projecting a projection image according to the projection signal. The optical device includes an optical sensor. The optical sensor is capable of sensing the identification signal of the projection image, outputting a detection signal corresponding to the identification signal and wirelessly transmitting the detection signal to the projector. A projection system including a projector and an optical sensor is provided as well.

Abstract: An analytical cell including a lightguide with a plurality of conduits filled with a migration medium. The medium, the lightguide and a surrounding medium have refractive indices selected such that light entering the lightguide is internally reflected within the lightguide to provide substantially uniform illumination of the conduits.

Abstract: A display device that includes a first substrate having pixel electrodes; a second substrate having a color filter corresponding to the pixel electrodes to display images; a photo switching element disposed at the first substrate; a red or green color filter corresponding to the photo switching element formed at the second substrate to sense an amount of external light; a driving controller configured to output a driving control signal responsive to the amount of external light sensed by the light sensing unit; and a light generation unit configured to provide the display unit with an internal light controlled by the driving control signal. This photo sensor is well suited to human-eye luminosity and uses external light to determine how much backlight is needed.

Abstract: The invention includes an image sensor, a shutter which opens/closes by making a front curtain and a rear curtain travel, a light source which illuminates the image sensor, a control unit which performs control to make the front and rear curtains travel with a predetermined time shift to form a slit-like opening, and to make the light source emit light a predetermined period of time after the start time of traveling of the front and rear curtains, a detection unit which detects the deviation between the position of an image of the recorded slit-like opening and a predetermined reference position, a computation unit which calculates the error between the traveling start timing of the front and rear curtains on the basis of the detected deviation, and a correction unit which corrects the calculated error between the traveling start timing of the front and rear curtains.

Abstract: A process for measuring the mercury concentration within a hydrocarbon is provided that enables the mercury concentration to be measured simply and quickly, and with good reliability and good reproducibility. A process for measuring the mercury concentration within a hydrocarbon includes the steps of placing and weighing the hydrocarbon in a sample boat 12 containing an adsorbent that contains a metal capable of forming an amalgam with mercury, and heating the hydrocarbon inside the sample boat 12 in a combustion furnace 13, together with the adsorbent, and measuring the quantity of mercury within the thus generated gas.

Abstract: An orifice test calibration device tests the functionality of protective mask testers. The orifice test calibration device has a semi-rigid tubular channel with one end for sealing the flow outlet port of the protective mask tester and a second end for sealing the vacuum inlet port of the protective mask tester. The device also includes a sealable opening within the tubular channel and an insertable orifice plug having a set diameter for insertion into the sealable opening in order to calibrate the protective mask tester.

Abstract: The invention is an apparatus and method including hardware and software, which allows collecting and analyzing data to obtain information about mechanical properties of soft materials in a much faster way. The apparatus can be used as a stand-alone deice or an add-on to the existing AFM device. The apparatus allows collecting dynamical measurements using a set of multiple frequencies of interest at once, in one measurement instead of sequential, one frequency in a time; measurements.
