Abstract: A device for measuring the optical turbidity, i.e., the soot components in discharge gases of diesel engines, which is relatively simply constructed, operates safely and enables a simple handling even with differently structured measuring devices. This result is achieved in that a controller for controlling the light density of the measuring light beam is optically coupled with a light source. A sample and hold circuit is provided with the values of a measuring detector and the control detector fed to a sample and hold circuit in a time multiplex manner with the measuring values processed in a computer unit. Control values are fed to the light source by means of a control loop. In addition, the computer unit is capable of storing a plurality of measuring values or turbidity values and average value of the stored peak values, whereby the peak values are determined by a dynamic measuring of a defined number of measuring cycles. Moreover, a device is provided which feeds motor related parameter to the computer unit for triggering of measuring value determination and measuring value calculation.

Abstract: An inspection system is configured for use with a conveyer apparatus including carrier bars. Each carrier bar conveys pellet-shaped articles along a predetermined path. The inspection system includes at least one camera unit for sensing a predetermined characteristic of the pellet-shaped articles, a removal unit, and a controller. The removal unit, downstream from the at least one camera unit, removes selected pellet-shaped article(s) from the carrier bar(s) depending on whether the characteristic is sensed by the at least one camera unit. The controller is in communication with the at least one camera unit and the removal unit. The controller provides a signal to the removal unit in accordance with the sensed characteristic. The removal unit includes a rotatable ejection drum having extended vacuum nozzles along its length, equal to the number of articles conveyed in each carrier bar. Each vacuum nozzle selectively removes article(s) from the carrier bar(s) by suction.

Abstract: Among other things, this application describes systems and methods for detecting gas using a wide band light source, and at least two narrow band light sensors, wherein each sensor may be operable to detect light at a different range of wavelengths. Additionally, the gas detector device may comprise a color changing indicator operable to react with gas in the air to change color, wherein different gases may react to create different colors, and wherein the sensors detect light reflected by the color changing indicator from the wide band light source. The gas detector device may comprise a processor in communication with the at least two light sensors operable to receive detected reflected wavelength information from the light sensors, and determine the type of gas that reacted with the color changing indicator based on the color detected by the sensors, wherein each color may be associated with a different type of gas.

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: Systems and methods for controlling fluids in microfluidic systems are generally described. In some embodiments, control of fluids involves the use of feedback from one or more processes or events taking place in the microfluidic system. For instance, a detector may detect one or more fluids at a measurement zone of a microfluidic system and one or more signals, or a pattern of signals, may be generated corresponding to the fluid(s). In some cases, the signal or pattern of signals may correspond to an intensity, a duration, a position in time relative to a second position in time or relative to another process, and/or an average time period between events. Using this data, a control system may determine whether to modulate subsequent fluid flow in the microfluidic system. In some embodiments, these and other methods can be used to conduct quality control to determine abnormalities in operation of the microfluidic system.
