Abstract: A device for controlling an amount of light of a lighting unit for use in an endoscope, used to view an image of an object. The device includes a light shield for shielding light generated by a light source and transmitted to the endoscope. A stepping motor drives the light shield for a series of predetermined time intervals. Brightness of the image is detected during each of the time intervals and pulses are generated during each of the time intervals motor hunting is detected. The number of pulses generated is determined in response to detection of hunting and when hunting is detected the number of pulses is reduced. The pulses generated are used to drive the stepping motor in each of the plurality of time intervals.

Abstract: Calibration spots of optically-characterized material placed in the field of view of a spectroscopic system allow calibration of the spectroscopic system. Response from the calibration spots is measured and used to calibrate for varying spectroscopic system operating parameters. The accurate calibration achieved allows quantitative spectroscopic analysis of responses taken at different times, different excitation conditions, and of different targets.

Abstract: A voltage detecting circuit is capable of detecting the voltage to be detected at high precision, is small in size, and is low in manufacturing cost. A first photo coupler and a second photo coupler are interposed between voltage input terminals to which the voltage to be detected is applied. The photo coupler has light emitting elements connected parallel reversely, first voltage generator for generating a voltage depending on the photo detector side currents of the first photo coupler and second photo coupler, a differential amplifier whose one input terminal receives the voltage generated by the first voltage generator. A third photo coupler and a fourth photo coupler having light emitting elements are connected parallel reversely for receiving the output current of the differential amplifier, and a second voltage generator for generating a voltage corresponding to the photo detector side currents of the third photo coupler and fourth photo coupler. The voltage generated by the second voltage generator is fed into the other input terminal of the differential amplifier, so that the voltage depending on the light emitting element side currents of the third photo coupler and fourth photo coupler is matched with the voltage fed into the voltage input terminals.

Abstract: Process and apparatus for measurement of brightness of milled products, especially flour, are disclosed. The process is of the general type in which the surface of a layer of flour is illuminated, and the returned quantity of light is taken to an optical electrical transducer. A light source is used for illumination, and the light beam is optically decomposed into at least two part-beams (reference beam and measurement beam) for transmission to the transducer. At least one of the part-beams is cyclicly interrupted or broken into two essentially time-shifted measurement phases in such a way that of the two part-beams, only one of the two-part beams will strike the transducer during a first measurement phase, and during a second measurement phase at least the other part-beam will be applied to the transducer. The output signals of the transducer are taken to a memory which intermediately stores the output signals of one measurement phase until the output signals of the following measurement phase appear, so that both output signals can be taken simultaneously to an evaluating device for determination of the relative brightness value of the measurement beam in comparison to the reference beam.

Abstract: The eluent from a liquid chromatography column is irradiated, while flowing between the column and a conventional detector adapted to detect a given property, in order to convert a known or suspected constituent photochemically to a species which possesses the property or to one in which the property is changed in magnitude (enhanced or reduced) to a substantial degree. The irradiation may be by UV or visible light, and the property may eg be fluorescence with, or absorbance of, UV or visible light. The method can increase the sensitivity and/or selectivity of detection, eg in the presence of interfering substances which do not react to irradiation in the same way as the constituent of interest.Apparatus for performing the method may comprise a long translucent small-bore tube shaped to a configuration which surrounds a light-source and which is connected between the column and the detector.

Abstract: The light output of a doubly pulsed laser is monitored by converting the two successive light pulses into corresponding electrical pulses and feeding the electrical pulses to a pair of parallel connected circuit channels. A first one of the circuit channels is conditioned to receive the first electrical pulse while a second one of the circuit channels is rendered immune to that pulse. The first electrical pulse charges a capacitor to a voltage proportional to the pulse amplitude and the voltage is displayed on a direct current voltmeter. The second circuit channel is conditioned to receive the second electrical pulse while the first circuit channel is rendered immune to that pulse. The second electrical pulse charges another capacitor to a voltage proportional to the pulse amplitude and the voltage is displayed on another meter. Both voltages are maintained for comparison with one another, after which the circuit channels may be reset to their initial condition for reception of the next set of electrical pulses.
