Abstract: In a exhaust smoke sensor a light emitter (20) generates a light beam which passes through a region containing the exhaust gas to a first light sensor (38). To reduce interference the light emitter (20) is driven by a near square wave signal (40) produced by passing a square wave (40A) through a low pass filter (40B).

Abstract: A measurement system for measuring blood characteristics includes a controller, an emitter, a sensor, a reference photo sensor, and a mask. The emitter emits light at a plurality of wavelengths from a first side of a blood flow channel to a second side of the blood flow channel. The sensor is provided on the second side of the blood flow channel. The reference photo sensor is provided on the first side of the blood flow channel. The mask is provided on the first side blocking reflected light other than from the light from the emitter to enter the reference photo sensor. The controller compensates measurements from the sensor based upon measurements from the reference photo sensor.

Abstract: Using an LED element as a light source, a photometric unit including the light source, a light receiving element and other components therebetween is reduced in size. A holder 30 detachable from the device as a unit holds a light emission unit 15 formed of an LED and a light receiving element 21, and the holder is placed inside a thermostatic chamber 18 which holds a constant temperature fluid 17. Thus, the photometric unit is reduced in size.

Abstract: Vorrichtung zur Bestimmung der Konzentration einer oder mehrerer Substanzen in einem fluiden Medium, wobei die Lichtemission einer Multiquantumwell-Leuchtdiode (MQW-LED) zur Absorptionsmessung genutzt wird. Das emittierte Licht interagiert in einer Messanordnung mit der zu bestimmenden Substanz und wirkt in einer Detektoreinheit mittels eines optischen Filters auf einen Absorptions- und einen Referenzdetektor, die ein Messsignal und ein Referenzsignal generieren. Aus dem Vergleich dieser Signale wird die Konzentration der zu bestimmenden Substanz ermittelt.

Abstract: The invention relates to an apparatus for determining the element coverage on a surface (G) having a UV radiation source (1) which comprises at least one UV light-emitting diode (Ia) and the UV radiation of which excites the element to fluoresce, and having a detector unit (2) for detecting the fluorescent radiation. According to the invention, the apparatus is characterized in that the beam guidance is carried out, by alignment of the UV radiation source (1) and the detector unit (2) relative to the surface (G) and/or by use of a wavelength-selective beam splitter (6) in the beam path, such that the UV radiation reflected back by the surface (G) is kept away from the detector unit (2).

Abstract: A method and apparatus for automatically selecting test types for an analytical meter system (10) based on the insertion into the meter of a test element (30). The test element can be an analytical element, formed by a test strip with control fluid applied thereto; or a standard element, or a standard strip exhibiting known optical properties. By inserting the test element into the analytical meter system, optical properties are measured and the existence of relationships between the measurements are ascertained.
