Abstract:
An apparatus for detecting variations in light output of an electroluminescent (EL) device is described. The EL device includes a transparent substrate having a first edge extending in a first direction and a plurality of EL emitters disposed over the face of the substrate in the first direction, and some of the light emitted by each EL emitter travels through the substrate and out of the first edge. A light sensor physically separated from the first edge senses the light travelling out of the first edge. A controller stored first sensed light at a first time and second sensed light at a later second time and computes a variation in light output of one or more of the EL emitters in the EL device using the stored first sensed light and second sensed light.
Abstract:
A detection system and method for detecting an object such as a vessel or a cap on a vessel. The system includes an imaging device having a lens with a field of view for registering and processing an image of the object, an illumination device(s) for actively illuminating the object, a dark background portion, and an auxiliary light reflective area(s) for passively illuminating an edge portion of the object using reflections of illumination from the illumination device(s). The auxiliary light reflective area(s) is/are disposed adjacent to the dark background portion out of the field of view of the lens. Images of the object are subsequently compared to images of reference objects.
Abstract:
An oxygen concentration measuring device is provided for determining an oxygen concentration of a gas in a sample volume. The device includes an optical device configured for irradiating the sample volume containing oxygen with a first UV radiation intensity, at least one wavelength of which is close to a spectral absorption line of oxygen, a magnetic field generator configured for applying a magnetic field at the sample volume, and a UV light detector configured for measuring a second UV radiation intensity coming from the sample volume. The oxygen concentration in the sample volume is determined on the basis of the applied magnetic field and the measured second UV radiation intensity.
Abstract:
An insolation sensor is disclosed and is used to determine a solar light intensity as a basis for evaluating electric power generated by solar modules exposed to the solar light intensity. The insolation sensor includes an outer surface including a light entrance window, and at least one photo sensor configured to measure the solar light intensity. The at least one photo sensor is arranged behind the light entrance window. The insolation sensor further includes a detector device configured to detect precipitation and/or a resulting deposit on the surface which both affects the insolation sensor and the solar modules.

A fluorescent color calibrator for calibrating RGB pixel values is provided. The fluorescent color calibrator includes a plurality of fluorogenic compounds adapted to fluoresce in a visible color spectrum; and a second plurality of fluorogenic compounds adapted to fluoresce in multiple visible gray spectrums. Also provided is a method for using the fluorescent color calibrator to standardize fluorescent colors when viewing with an RGB monitor.
Abstract:
The present invention is directed to a method of calibrating sensitivity gain. In a preview mode, an imaging device is calibrated by a standard light source, therefore obtaining standard sensitivity gain of the preview mode. In a capture mode, the imaging device is calibrated by the standard light source, therefore obtaining standard sensitivity gain of the capture mode. A gain ratio of the standard sensitivity gain of the capture mode to the standard sensitivity gain of the preview mode is determined, and is then used to deduce the exposure parameters of the capture mode according to the exposure parameters of the preview mode.
Abstract:
A calibration device 21 according to the present invention is a member used for white calibration of an optical characteristic measuring apparatus 1 for measuring an optical characteristic of a specimen arranged to close a measuring opening and is used together with a spacer 24. Accordingly, such a calibration device 21 can perform more accurate white calibration by preventing formation of an interference pattern by the spacer 24.
