    Abstract: A horizontal cable animal barrier for mounting on a cable to deter animal passage including a plurality of roller elements each having a central hole for rotatably mounting on a cable and a spacer element between each pair of roller elements and also having a central hole for rotatably mounting on the cable, in which the spacer elements are of a different size than the roller elements on either side to present an uneven, rotating barrier to animals on the cable to prevent the animals from passing.

    Abstract: A pair of optical gratings are used to modulate light from an object, and the modulated light from either optical is used to determine the velocity of the object. Each optical grating is offset from a reference focal point by the same distance, one grating being offset in a positive direction, the other in a negative direction. Signals produced in response to the modulated light can be processed to determine a direction in which a primary collection lens should be moved in order to improve a focus of the imaging system on the object. The lens is moved incrementally in the direction so determined, and the process is repeated until an optimal focus is achieved. In a preferred embodiment, the signals are weighted, so that the optical grating disposed closest to the optimal focus position contributes the most to velocity detection.

    Abstract: A system for collecting images at multiple wavelengths for image analysis of biological specimens. The process separates contrasts for images of a biological specimen prepared with a chromogen. Light wavelengths matched with each chromogen optimize separation for each image. Computing attenuation coefficients and extinction coefficients for each chromogen provides for determination of the concentration of each chromogen. A chromogen separator allows for subtracting predetermined chromogens to generate new images and aid in identification of cell morphology. The system can perform the image analysis of the new images using image processing techniques such as segmentation, feature calculation and object classification. At each stage of image processing, data from each of the new images may influence the processing of the other images.
