Abstract:
A wavelength correction function provides corrected reflectance values from actual reflectance values taken in a reflectance-base instrument. The correction is provided as a function of measured reflectance values and a predefined set of high resolution reflectance values established for the reflectance-based instrument implementing the wavelength correction function.
Abstract:
An automatic analytical apparatus includes a reaction container for mixing a sample with a reagent to react the sample to the reagent, a measurement unit that irradiates a reaction solution in the reaction container with light and measures the intensity of transmitted light or scattered light, a control unit that processes time-series light intensity data obtained through the measurement in the measurement unit, a storage unit that stores one or more approximation functions each approximating to a time-series change in the light intensity data, and an output unit that outputs a processing result of the control unit. The control unit selects any one of the approximation functions stored in the storage unit, calculates an approximate curve indicating a time-series change in the light intensity data using the selected approximation function, calculates deviation feature information based on deviation information between the light intensity data and the approximate curve, and detects and classifies an abnormality included in the light intensity data using the deviation feature information.

Abstract:
A chemical vapor sensor (100) is provided that passively measures a chemical species of interest with high sensitivity and chemical specificity. In an aspect, ethanol vapor in a vehicle cabin is measured, and sufficient sensitivity is provided to passively detect a motor vehicle driver that exceeds a legal limit of blood alcohol concentration (BAC), for use with vehicle safety systems. The sensor (100) can be situated in an inconspicuous vehicle cabin location and operate independently without requiring active involvement by a driver. A vapor concentrator is utilized to amplify a sampled vapor concentration to a detectible level for use with an infrared (IR) detector. In an aspect, in comparison to conventional chemical sensors, the sensitivity of detection of ethanol vapor is increased by a factor of about 1,000. Further, a single channel of infrared detection is utilized avoiding spurious infrared absorption and making the chemical vapor sensor (100) less costly to implement.
Abstract:
An apparatus, program product and method incorporate an extensible modular communication executive for use integrating one or more electronic devices with one another with reduced customization overhead. A modular architecture is used to facilitate message-based communications in such a manner that queuing strategies, business rules and the like may be accommodated within a message-based environment in a reliable and efficient manner. Through the use of a modular architecture, application-specific software components can be assembled together to readily adapt a generic message-based system for use in a specific application. Moreover, intelligent pre-validation of messages may be implemented in such a modular architecture to permit a business rule-independent messaging infrastructure to be readily adapted to support specific business rule requirements for a particular application.

Abstract:
PURPOSE: To enhance the reliability of spectrophotometer, by such a simple constitution that a first sector and a second sector each having a pervious part and a reflective part are respectively used as a beam splitting one and a beam coupling one while spectral diffraction is performed by a frequency component detecting system. CONSTITUTION: The light from a light source 1 for an infrared region is reflected by a concave mirror 2 and the reflected light is split into two light beams by a first rotary sector 3. The first sector has a reflective part and a pervious part each having a specific pattern and the reflected light is converted to a reference light beam 14 while the pervious light to a sample light beam 15 by both parts. A second sector 9 has a pervious part and a reflective part each having a specific pattern and the reference light beam 14 permeated through the second sector 9 and the sample light beam 15 reflected by the second sector 9 mutually passes a monochromator 12 to be incident to a detector 13. The first sector 3 and the second sector 9 are synchronously rotated at a rotation ratio of 1:4 and the ratio of sample beam/reference beam is directly calculated from the output of the detector 13 by a frequency component detecting system.
