Abstract: Due to the size of the devices used for the excitation and measuring of light, conventional sensor elements for optically determining the concentrations of substances contained in gaseous and liquid samples, featuring an indicator layer with one or more indicator substances, are not well suited for use with microanalysis equipment, nor are they easy to mass-produce. These disadvantages are eliminated by using a unitary sensor element having a carrier layer, at least one photosensitive element with electric contact leads in contact with the carrier layer, and an indicator layer containing an indicator substance.

Abstract: Blood gases and the like are monitored by a single probe having multiple dye wells and dyes immobilized in the wells, the dyes being exposed to the blood gases. Optical fibers and waveguides connected to the dye wells permit light to be directed from a light source to the dyes and the light due to absorption or the spontaneous emission of the dye returned to a light detector. The intensity, phase shift or other mechanism of the returned radiation is a measure of the partial pressure of a respective blood gas.

Abstract: Method of generating a correction function for a light-emitting diode (LED) testing process, including: detecting light emitted by a reference LED and reflected from inactive LEDs on a panel within a field of view of a detector; varying a number of the inactive LEDs to derive uncorrected values of an optical parameter as a function of the number of inactive LEDs; detecting light emitted by the reference LED, or by an active LED having identical optical properties, in the absence of any other LEDs, to determine at least one reference value for each optical parameter; and calculating differences between the uncorrected values and each reference value to generate the correction function, the correction function being based on the number of inactive LEDs which are arranged within the field of view of the detector in the light detecting step.

Abstract: A device for measuring at least one characteristic of a fluid is provided. The device comprises a measuring channel which is designed for conducting fluid flow therethrough and which is defined by a wall and a substrate. An inlet orifice and an outlet orifice are provided for conducting fluid into and out of the measuring channel and at least one sensor is located adjacent the measuring channel for measuring the characteristic of the fluid. The wall has outer portions, which are sealing adhered to the substrate, and upwardly bent portions, which partially define the measuring channel. The outer portions and the upwardly bent portions are of substantially the same thickness. The wall is preferably made of a synthetic resin, glass, ceramic, silicon nitride, silicon monoxide, silicon dioxide, or combination of these materials.
