Abstract: The present invention relates to a device for measuring both the colour and turbidity of a liquid sample. (16,40,48) LEDs are used as light sources and reference detectors (13,44) are included to control the output of the LEDs. The device is also capable of monitoring and correcting for fouling of optical surfaces. The device is intended to be installed in-line in a main water supply line. The device can be used in domestic water meters or on sewage treatment sites to monitor the effluent discharged back to the river.

Abstract: The invention relates to a method of controlling a product analysis spectrometer, the spectrometer comprising a light source (LS) comprising several light-emitting diodes (LD1-LD4) having respective emission spectra covering in combination a band of analysis wavelengths, the method comprising steps consisting in: providing a supply current (I1-I4) to at least one of the light-emitting diodes so as to illuminate it, measuring a luminous intensity (LFL1- LFL4) emitted by the light source by measuring a current at a terminal of at least one other of the light-emitting diodes which is kept unlit, determining as a function of each measurement of luminous intensity a setpoint value (LC1-LC4) of the supply current for each lit diode, and regulating the supply current for each lit diode so that it corresponds to the setpoint value.

Abstract: Using an LED element as a light source, a photometric unit including the light source, a light receiving element and other components therebetween is reduced in size. A holder 30 detachable from the device as a unit holds a light emission unit 15 formed of an LED and a light receiving element 21, and the holder is placed inside a thermostatic chamber 18 which holds a constant temperature fluid 17. Thus, the photometric unit is reduced in size.

Abstract: An automatic analyzing apparatus which can make an adjustment to a target temperature so as to stabilize the light intensity of an LED and also can make the adjustment to that temperature in a short time is provided. The automatic analyzing apparatus in which an LED is used for a light source 114 includes a temperature adjusting mechanism 201 for the LED, and the temperature adjusting mechanism 201 includes a metal member 202 provided with the light source 114, a pair of metal pipes (water-flowing pipes) 203 buried in the metal member 202 and allowing constant-temperature bath water to flow therein, and pins (small metal piece members) 204 bringing only a heat-generating lead 252 of the light source 114 into direct contact with the metal member 202. Therefore, the temperature adjusting mechanism 201 can make an adjustment to a target temperature so as to stabilize the light intensity of the LED, and the adjustment to that temperature can be made in a short time.

Abstract: The invention relates to an optoelectronic device for measuring the water content in a plant element (10) and to an apparatus designed to evaluate and monitor in real time the state of hydration of the plant covers (10). It enables measurements to be taken repeatedly at certain time intervals on the same material without damaging or destroying it. The device comprises an optoelectronic probe (1) connected to a measurement module (2), the probe (1) comprising: i) a first light source (3) emitting at a wavelength corresponding to a strong water absorption band; ii) optionally, a second light source (4) emitting at a wavelength close to the first source (3) and weakly absorbed by water; and iii) a photo receiver (5) having a spectral response that corresponds to the emission bands of the first light source (3) or of the first (3) and second (4) light sources, the device including means (16) or modulating the average optical power emitted by the light source or sources (3) at a defined frequency, and means (8) for synchronously detecting the light received by the photoreceiver (5). The probe (1) can be carried on a movable member having two jaws (21, 22) between which the specimen (10) is engaged without being in compressive contact therewith.

Abstract: The invention relates to a device for inspecting eggs for the presence of blood. The device comprises a light source in order to pass light at a first wavelength which is not selectively absorbed by blood and light at a second wavelength which is selectively absorbed by blood through an egg to be inspected. Furthermore, the device comprises detection means for converting the light transmission through the egg to be inspected for each of the two wavelengths into corresponding signals, each of the said signals being representative of the light transmission at the relevant wavelength. The device also comprises signal-processing means which are transmission associated with the first wavelength and the light transmission associated with the second wavelength based on the signals emanating from the detection means and to emit a decision signal which is representative of the decision whether or not an egg contains blood on the basis of this ratio. According to the invention, the light source comprises one or more identical LED's (Light Emitting Diode) for generating light which passes through the egg. In use the one or more LED's emit light within a certain narrow spectrum, which spectrum comprises both the first and the second wavelength.

Abstract: A sensing apparatus and method for use in the optical absorption analysis of the NO2 content of a gas sample. The apparatus and method employ radiation from a semiconductor radiation source. The emission spectrum of the radiation has a maximum wavelength of about 600 nm, preferably 380 - 520 nm. The radiation is passed through the gas sample and sensed by a detector to provide an output signal indicative of the NO2 content of the gas sample. The sensor apparatus and method may be employed in conjunction with other gas sensing apparatus and methods, such as IR CO2 measurement or NO sensing.
