    Abstract: A gas sensor includes a light source, a power source in operative connection with the light source and a control system in operative connection with the light source and the power supply. The control system is adapted to control power input from the power source to the light source such that the time period of the control frequency is shorter than the thermal time constant of at least one of (i) the infrared light source, (ii) the gas within the sensor, or (iii) a detector of the sensor. The time period of the control frequency can, for example, be no greater than ⅓ of the thermal time constant, no greater than 1/10 of the thermal time constant, or even no greater than 1/20 of the thermal time constant. A feedback signal can be provided to the control system assist in achieving control.

    Abstract: A chemical vapor sensor 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 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 less costly to implement.

    Abstract: A method of analysis, analysis system, program product, apparatus, and method of supplying analysis of value incorporating the use of at least one data acquisition device, a central processor, and a communication link that is connectable between the data acquisition device and the central processor. The central processor is loaded with multivariate calibration models developed for predicting values for various properties of interest, wherein the calibration models are capable of compensating for variations in an effectively comprehensive set of measurement conditions and secondary material characteristics. As so configured, the calibration models can compensate for instrument variance without instrument-specific calibration transfer. Measurement results generated by the central processor can be transmitted to an output device of a user interface.

    Abstract: Microarray readers and methods that compensate for target spots that are too dim or too bright for the microarray reader to accurately measure. The readers adjust the amount of light directed at or received from specific non-acceptable target spots, such that dim spots receive more excitation light and overly bright spots receive less. This increases or decreases, respectively, their measured brightness, which in turn effectively increases the range over which a microarray reader can accurately measure the spots, and can also improve the signal-to-noise ratio and other aspects of the measurements.
