Abstract: An improved ear thermometer head includes a waveguide, a thermometer and a waveguide protective cover. The outer detecting end face of the waveguide protective cover is integrally formed and seamlessly connected to a transparent piece so that the outer detecting end face of the waveguide protective cover is in an enclosed and seamless state to shield an exposed clearance between the interior of the waveguide protective cover and the waveguide, thereby preventing entry of pollutants, such as water and dust. The outer detecting end face is substantially transparent, and is hardened and polished to effectively permit accurate light penetration. If there is water on the outer detecting end face or if it is dirty, it can be wiped clean, sterilized or washed. As such, the cleanliness and hygiene of the outer detecting end face of the waveguide protective cover is ensured, and besides, use of an additional cap to cover the waveguide protective cover is eliminated.

Abstract: First, monochromatic near infrared light in a wavelength range of 700 nm-1100 nm from the slit of the near infrared apparatus 1 is applied to a reference ceramic plate through the optical fiber 7 to measure a transmitted light intensity of the ceramic plate which is a reference material for spectrum measurement. Next, in place of the ceramic plate, the test tube 4 containing a liquid sample of which the temperature has been adjusted at a predetermined temperature by a water bath and the like is inserted into the housing portion 5. The transmitted light intensity of the liquid sample is then measured using the same procedure as above. A so-called near infrared absorption spectrum in which absorbance has been plotted against wavelengths is displayed on the screen of the computer 2. Information about each object characteristic is extracted from the spectrum data using a calibration equation.

Abstract: A method of the present invention includes exposing a structure to first electromagnetic radiation including at least one wavelength absorbed by a predetermined substance that is to be detected. Such substance can be water, a water-soluble substance, or fungi, the presence of which can be a significant problem in a structure such as a house or building. The method includes sensing second electromagnetic radiation from the structure, the second radiation based on the first radiation. The method also includes determining whether the substance is present in the structure, based on the sensed second radiation. If the substance to be detected is water and the determining step reveals a water-suspect area in the structure, the method can include testing the water-suspect area of the structure to determine whether water is present therein. If water is confirmed by the determination to be present in the structure, the method can include a step of determining the source of the water. Proper identification of the source of a water problem permits appropriate measures to be taken to correct the water problem. The invention also includes similar methods for the detection of a water-soluble substance in a structure, such as carbonate, phosphate, sulfate, chloride or other minerals indicative that ground water is the source of a water problem. The invention also includes a similar method for the detection of fungi which grows in moist areas of a structure, to which many people are allergic.

Abstract: Method and apparatus are provided for visibly outlining the energy zone to be measured by a radiometer. The method comprises the steps of providing a laser sighting device on the radiometer adapted to emit more than two laser beams against a surface whose temperature is to be measured and positioning said laser beams about the energy zone to outline said energy zone. The apparatus comprises a laser sighting device adapted to emit more than two laser beams against the surface and means to position said laser beams about the energy zone to outline said energy zone. The laser beams may be rotated about the periphery of the energy zone. In another embodiment, a pair of laser beams are projected on opposite sides of the energy zone. The laser beams may be further pulsed on and off in a synchronised manner so as to cause a series of intermittent lines to outline the energy zone. Such an embodiment improves the efficiency of the laser and results in brighter laser beams being projected. In yet another embodiment, a primary laser beam is passed through or over a beam splitter or a diffraction grating so as to be formed into a plurality of secondary beams which form, where they strike the target, a pattern which defines an energy zone area of the target to be investigated with the radiometer. Two or more embodiments may be used together. A diffraction device such as a grating may be used to form multiple beams. In a further embodiment, additionally laser beams are directed axially so as to illuminate the center or a central area, of the energy zone

Abstract: An on-the-go sensor for determining the sugar content of an agricultural product, such as a sugar beet, during harvesting or at other times. The sensor is coupled to a harvester/defoliator and uses a knife to slice a cross-section from the crown of the sugar beet during harvesting. An illumination chamber radiates the exposed crown, and a sensor head receives the reflected radiation. A spectrometer converts the reflected radiation to a spectral signal. A computer digitizes and processes the spectral signal to produce data points relating to the sugar content of the sugar beet. The processing of the data points includes normalization, linearization, and other techniques. One of the techniques eliminates the conventional need to use the spectral signature of a separate physical standard as a reference.

Abstract: Method and apparatus for sorting plastic materials on a recycling operation wherein near and infrared energy illuminates particles of flake plastic including such as PET, PVC and PS transported along a conveyer line and the contaminant ingredients are identified and ejected from the stream of preferred particles. More accurate sorting, and thus a higher quality sort may be performed where the contaminant materials and the preferred materials are identified by comparing ratios of levels of signals of energy transmitted through or reflected from the particles, the levels of signal being obtained by filtering the energy from the particles through bandpass filters, one filter of which is centered on the absorptive peak of a contaminant and another filter is centered on a frequency exhibiting the energy level of the preferred material equal to that occurring at the center of the filter for the contaminant absorptive peak. Collateral method and apparatus include placing the fiber optic energy receivers of the transmitter and received information at a distance from the receiver a factor or five or more of the ratio of the field of view of a fiber at the particle stream to the maximum offset of the receiving fibers in the faceplate, as those opposite each other on a diameter of the faceplate.
