Abstract: L'invention se rapporte à des procédés et à un appareil permettant de construire des capnographes à infrarouge sans obturateur et optiquement stabilisés. Ces capnographes fournissent la concentration absolue des constituants du flux d'air respiratoire d'un patient, sans les problèmes de dérive thermique normalement associés aux détecteurs à thermopiles, ce qui permet d'obtenir un dispositif ayant un degré de précision élevé. La présente invention élimine la nécessité de recourir à un obturateur mécanique pour moduler le faisceau infrarouge incident, ainsi qu'à une source modulée, ce qui augmente la fiabilité et le temps de réponse des dispositifs décrits. Des capnographes qui sont sensiblement non affectés par les variations de la température ambiante à laquelle ils fonctionnent sont obtenus par la connexion en série de paires de thermopiles (12, 14, 22, 24, 32, 34) à filtres (60, 61, 62, 16, 18, 26, 28, 36, 38) et par le traitement du signal différentiel qui en résulte (242).

Abstract: A remote reading spectrophotometer (10) is provided having the capability to accurately measure spectral reflectance at relatively long sample distances. A first illumination optics arrangement (14) assures uniform illumination to a portion of the sample and a second optical means (20) focuses the reflected image of part of the illuminated sample onto a poly­chromator (22). Reference beam means are provided so that the polychromator sequentially measures the spectral characteristics of the reference beam and the sample. Continuous monitoring of the illumination at select wavelengths provides illumination normal­ization data so that a microprocessor (40) can normalize the illumination and compare the reference beam and sample measurements to accurately determine the spectral reflectance characteristics of the sample. Angular and raster scanning capability is also provided.

Abstract: The present invention relates to an improved dual beam multichannel spectrophotomer employing a simple and novel optical system in combination with photodiode arrays and a unique logrithmic data converter to convert light signals to absorbance. In particular, the optical system utilizes optical elements in a novel arrangement to direct a pair of equivalent sample and reference beams in an essentially parallel formation respectively through a sample and reference cell and to focus and direct the emergent sample and reference beams to a single flat horizontally ruled grating which disperses each of the sample and reference beams respectively onto a pair of vertically disposed photodiode arrays whereby the light signals are converted into absorbance units (AU) by an unique logarithmic data converter. The spectrophotometer is highly accurate, has very low drift, less than 2 x 10⁻⁴ AU/°C, and very low noise, less than ±2 x 10⁻⁵AU. The dual beam multichannel spectrophotomer is particularly suitable for use in high pressure liquid chromatography to record the absorbance spectrum of the samples as they are being eluted from the chromatographic column.

Abstract: Process and device for measuring gloss in a surface with a light source, which emits light towards the surface, and with a photosensitive detector, which receives the light reflected by the surface and converts it into an electrical signal value. Said device includes a storage unit, where a computing rule for calculating the gloss parameter is stored, a calculation unit, which determines a gloss parameter on the basis of the electrical signal value using the computing rule, and a display unit, which displays the gloss parameter calculated. Five or more pairs of reference values are stored in the storage unit, each pair of reference values being comprised of a reference gloss parameter and of a corresponding reference signal value measured by the device using a reference surface. A comparative unit is also provided, which compares the signal value measured with said reference signal values and feeds at least the nearest higher and the nearest lower value to an interpolation unit.

Abstract: An apparatus and method for measuring a bodily constituent such as glucose or cholesterol by taking the sample taken from the body such as blood, saliva or urine. The sample is placed on a test strip inserted into the test block portion of the apparatus where the portion of the sample containing the constituent desired to be measured reacts with a chemical reagent. Products of this reaction have an absorbance/reflectance characteristic which is mathematically related to the concentration of the constituent in the bodily sample. The reflected light is absorbed by a photodiode and the output of the photodiode converted to a digital form where a microprocessor can calculate the concentration of the constituent using the mathematical relationship between the reflected light and concentration stored in memory means of the apparatus.
