    Abstract: Apparatus for detecting particulates (46) within a medium in a chamber (10) comprises a photo-detector (14) which is maintained at a stable low temperature by a Peltier type cooling device (42). Scattered light from the particulate (46) is focused by a spherical lens (34) onto the input face (30) of a rod lens (22). The latter has an optical pitch of 0.5 and transfers the image to its output face (25) whence it passes via a light pipe (18) to the sensitive area (16) of the photo-electric device (14). The rod lens (22) provides an inexpensive means for transferring the light and which provides a thermal barrier. Thus, although the photo-electric device (14) is held at a low temperature, the input face (30) of the rod lens (22) can be held at the temperature of the medium within the chamber (10) and is not subjected to the formation of mist or ice. The lens (34) is mounted by means of a collar ( 28) which is slidable into a position in which the lens (34) focuses the input light into the face (30) of the lens (22), and then secured in this position by ultra-violet-cured adhesive fillets (32, 34).

    Abstract: A moisture sensing assembly, adapted for mounting on the inner surface of a vehicle window or windshield to control vehicle accessories such as windshield wipers, maximizes the window are a being sensed while minimizing the size of the overall assembly. In the preferred embodiment, moisture on the outer window surface is detected by stacked rows of infrared energy receiving sensors spaced in angular relationship from stacked rows of infrared energy emitting diodes. The emitter diodes and sensors are preferably carried in separate emitter and detector mounting blocks slidably fitted in a rigid carrier. The sensor row closest to the window receives energy from the diode emitter row farthest from the window and vice versa. Energy barrier walls are provided in the diode and sensor support for blocking energy reflected by the inside window surface. The assembly is adapted for use with an electrical circuit which operates one emitter diode row and its corresponding sensor row while the other emitter and sensor rows are deactivated to prevent interference and false reflected signals from the other emitter row. Removable attachment to the window with a circular member provides ease of installation and improved positioning and orientation of the sensing assembly.

    Abstract: The present invention contemplates an arrangement for analyzing a plurality of components in a single specimen which comprises placing a diluted specimen into a storage cup which is part of a sample carrier system, containing storage and reaction cups, transferring aliquots of the diluted solutions of the sample from the storage to the reaction cups, presenting the rows of the reaction cups to a work station, sequentially, adding a reagent to each of the reaction cups and moving the reaction cups into a work field where beams of light passing through the various reaction cups can be scanned and the components contained in the reaction cups can be assayed by means of a single detector attached to a computer and print-out system.

    Abstract: Motion of an object of interest, such as a cell, has a variable velocity that can be varied on a cell-by-cell basis. Cell velocity is controlled in one example by packing cells into a capillary tube, or any other linear substrate that provides optically equivalent 360 degree viewing access, so that the cells are stationary within the capillary tube, but the capillary tube is translated and rotated mechanically through a variable motion optical tomography reconstruction cylinder. The capillary tube motion may advantageously be controlled in a start-and-stop fashion and translated and rotated at any velocity for any motion interval, under the control of a computer program. As such, there are several configurations of the optical tomography system that take advantage of this controlled motion capability. Additionally, the use of polarization filters and phase plates to reduce light scatter and diffraction background noise is described.

    Abstract: A method and apparatus for characterizing and screening an array of material samples is disclosed. The apparatus includes a sample block having a plurality of regions for containing the material samples, a polarized light source to illuminate the materials, an analyzer having a polarization direction different than the polarization direction of the polarized light source, and a detector for analyzing changes in the intensity of the light beams. The light source, together with a polarizer, may include a plurality of light beams to simultaneously illuminate the entire array of materials with linearly polarized light so that characterization and screening can be performed in parallel. In addition, the materials in the sample block maybe subjected to different environmental conditions or mechanical stresses, and the detector analyzes the array as a function of the different environmental conditions or mechanical stresses.
