    Abstract: A cassette reader (14) for detecting the status of stained samples (70) is provided. The colorimeter includes one or more high power emitting diodes (64a, 64b) as the source of illuminating the sample (70). An elliptical mirror (69), with a central aperture to permit the light to penetrate on to the sample (70), directs the scattered light on to its focal point at a detector (68). The colorimeter includes a microprocessor (62) which compares an output signal for the percent ratio value of the detected values of a sample (70) and a standard sample. The colorimeter housing (100) provides position sensors (18a-18d) which allow the identification of the well (16a-16d) being examined. Finally, the system is modified to measure cell motility by determining the ratio of motile sperms to total cell concentration.

    Abstract: The invention relates to a method and apparatus for determining the color and/or composition of a material. A sample of the material is illuminated with at least three illumination bands singly or in combination, said illumination bands collectively substantially spanning at least the visible range. The light reflected or transmitted by the sample is measured with at least four light detector elements responsive to light in wavelength bands which substantially span the visible range when the sample is illuminated. The measured reflected or transmitted light is compared to the light reflected or transmitted by a reference material of known apparent emissivity or transmissivity and the apparent emissivity or transmissivity of the sample is calculated therefrom.

    Abstract: An agricultural implement for spraying herbicide on weeds in a field without spraying herbicide on bare soil includes a photodetector circuit. The photodetector circuit includes a photodetector and an active filter. The photodetector is not AC coupled in parallel with an inductor/capacitor resonant circuit which tunes the active filter. As a result, changes in photodetector capacitance due to changes in ambient lighting conditions are not impressed across the resonant inductor/capacitor circuit and therefore do not adversely change the frequency and phase characteristics of the photodetector circuit.

    Abstract: Weeds (100) growing around the bases of the stalks of cotton plant (101) growing in a row (105 and 105A) in a cotton field are sprayed with herbicide without spraying the cotton stalks (101) or wasting herbicide on bare ground (107). The cotton plants are adequately mature that their stalks exhibit a significantly different spectral reflectance characteristic than the weeds typically growing amid the cotton. The cotton plants are adequately tall that the majority of the leaves of the cotton plants are disposed outside the area which can be sprayed using an electronically-controlled valve and nozzle (103). Light is transmitted toward an object (a cotton stalk, a weed, or soil) in the row and the reflected light is analyzed. If the object has a spectral characteristic of a growing weed, then the valve is activated and the object is sprayed with herbicide. If the object does not have the spectral characteristic of a growing weed, then the valve is not activated and the object is not sprayed with herbicide.
