Abstract: An envelope reflectance meter for evaluating the contrast between ink on a pre-printed envelope and the envelope itself and for calculating and displaying the print contrast ratio and the print reflectance difference is described. The device includes a portable housing having internally a pair of light sources which generate a reflected image of the envelope. The image passes through a lens, is reflected from a mirror, and is then displayed on a viewplate. An aperture is provided in the viewplate which passes a beam of light. The beam of light is then split and the two beams resulting analyzed for red content and green content. The analog signal produced is then converted to digital and the print contrast ratio and print reflectance difference calculated. A display is provided within the housing adjacent the viewplate whereby selectively the values for red light and for green light and comparisons between the readings for ink and the readings for the envelope are selectively displayed for an operator.

Abstract: A computerized emissions tester determines concentrations of HC, CO, and CO2 in exhaust emissions. An IR test bench assembly develops an analog voltage representative of the concentration of a particular gas in a sample gas of known concentration. Data related to calibration pressure, voltage offset and voltage gain are stored in non-volatile memory EEPROM. Algorithms relating voltage and concentration of the particular gases are included in software. The pressure of an exhaust emission is compared with the calibration pressure data in memory and a correction is applied to the tester output. The data relating to the voltage offset and gain factor are also used to compensate the tester output.

Abstract: A system for monitoring ambient carbon monoxide. Light from a source (14) is directed against a measuring element (10) which darkens in color as it absorbs carbon monoxide. The light reflected from the element is received by a photocell (16) which generates an electrical signal proportional to the intensity of the reflected light received thereby. The signal is sampled periodically, and stored in a microprocessor (24) which computes the rate of change of the signals. The periodic measurement of the intensity of the light can be varied in response to the rate of change of the light intensity measurement. When the rate of change reaches a level indicative of an unsafe level of ambient carbon monoxide, an alarm (34) is energized. Light from the source is simultaneously directed against a reference element (12) with the light reflected therefrom being received by a photocell (18) which generates an electrical signal proportional to the intensity of the light received thereby. A comparator (30) compares the electrical signal generated by the photocells and energizes an indicator (32) when the comparison indicates that the measuring element has absorbed sufficient carbon monoxide to require that the element be replaced.

Abstract: Assays (100) may be performed with a luminometer (400) having a chassis (405) that may include a reaction vessel chamber (610). The luminometer (400) may also include a light passage (640) that intersects the reaction vessel chamber (610). The luminometer (400) may also include a cap (415) that, when in a closed configuration, prevents light emitted by external sources from entering the reaction vessel chamber (610) and from entering the light passage (640). The cap (415) may provide access to the reaction vessel chamber (610) when in an open configuration. The luminometer (400) may also include a calibration light source (460) optically coupled to one end of the light passage (640) and a light detector (630) optically coupled to another end of the light passage (640). The light detector (630) may include a sensing element for receiving light from the light passage (640).

Abstract: A device may obtain a master beta coefficient of a master calibration model associated with a master instrument. The master beta coefficient may be at a grid of a target instrument. The device may perform constrained optimization of an objective function, in accordance with a set of constraints, in order to determine a pair of transferred beta coefficients. The constrained optimization may be performed based on an initial pair of transferred beta coefficients, the master beta coefficient, and spectra associated with a scouting set. The device may determine, based on the pair of transferred beta coefficients, a transferred beta coefficient. The device may determine a final transferred beta coefficient based on a set of transferred beta coefficients including the transferred beta coefficient. The final transferred beta coefficient may be associated with generating a transferred calibration model, corresponding to the master calibration model, for use by the target instrument.

Abstract: Technology is provided for an aqueous solution constituent analyzer. The analyzer includes an ultraviolet light emitting diode (LED) with a current source providing variable current thereto. A spectrometer is positioned for receiving light from the LED transmitted through an aqueous solution. A controller receives radiant flux data for a plurality of wavelengths and determines, based on the radiant flux data, a usable number of the plurality of wavelengths that satisfies a relative uncertainty threshold. The controller can increase the current to the LED if the usable number of wavelengths is less than a minimum threshold and calculate a concentration of a constituent of interest in the solution. The controller can also determine a peak wavelength of the plurality of wavelengths having the greatest intensity value, and decrease the current level to the LED if the peak wavelength has an intensity value greater than a saturation value for the spectrometer.

Abstract: An optical absorption gas sensor has an LED light source and a photodiode light detector, a temperature measuring device for measuring the LED temperature and a temperature measuring device for measuring the photodiode temperature. The sensor is calibrated by measuring the response of photodiode current at zero analyte gas concentration and at a reference analyte gas concentration. From these measurement, calibration data taking into account the effect of photodiode temperature on the sensitivity of the photodiode and, independently, the effect of changes in the spectrum of light output by the LED on the light detected by the photodiode with LED temperature can be obtained. Calibration data is written to memory in the gas sensor and in operation of the gas sensor, the output is compensated for both LED and photodiode temperature. The LED and photodiode can therefore be relatively far apart and operate at significantly different temperatures allowing greater freedom of optical pathway design.

Abstract: The present invention relates to a method for monitoring the filling of a capsule with a medicament, to a corresponding filling method, to the associated apparatuses, and to a computer program for controlling the method and the apparatus. In the monitoring method, after at least part of the capsule has been filled with a predefined filling mass of a predefined closed contour of the medicament, at least the filling mass in the part of the capsule after the filling operation is recorded using digital imaging in a first step, the contour of the filling mass in the part of the capsule is determined from the digital imaging recording in a second step, and the contour is analysed in a third step in order to assess the filling operation in comparison with the predefined contour. The invention provides for external influences on the image properties to be compensated for by controlling the optical system.
