Abstract: An optical data storage system is contemplated, one employing a data-modulated writing laser beam and a non-erasing reading laser beam of predetermined wavelength. 
     Improved optical media for such systems are described, these characterized by multiple layers whose optical characteristics and thickness are chosen to accommodate a prescribed writing and reading energy and wavelength and so provide an "anti-reflection" condition for unrecorded portions of the medium and a relatively higher reflectivity for recorded portions. A preferred optical medium includes a highly reflective aluminum layer, a relatively transparent polymer spacer layer overlying the reflective layer, and an optical absorber (recording) layer overlying the spacer layer. 
     Overcoating structure is specified in some detail; e.g., as a "soft pad" layer (e.g., fluoropolymer) on the absorber, with a "Hard" layer (e.g., radiation-cured acrylic) laid over the "soft pad" as an outer protective overcoat. Also, the "spacer" may be rendered as such a "soft pad".

Abstract: In an apparatus for automatically performing analytical testing of individual distinct samples of biological fluids a test sample is reacted with test reagents and tested for a change in optical characteristics. A microprocessor memory (238) stores a plurality of different test protocols. An operator actuated keyboard (12) is used to select one of the test protocols from the memory. Individual distinct samples of biological fluid to be tested are received in a sample cell (26). The cell is heated to a preselected temperature. The apparatus transports an individual sample cell to a first location (36) to filter unwanted non-fluid material from the fluid to be tested and to remove excess fluid to be tested from the sample cell to cause a precise volume of fluid to remain in the sample cell for testing. After this, the apparatus transports the individual sample cell from the first location to a second location (48) for introducing a first reagent into the sample, and then transports the sample cell from the second location to a test location (50) where a second reagent is introduced into the sample. An optical detector (232,234) at the test location optically scans the sample in a vertical direction to detect a change in an optical characteristic of the sample. The apparatus provides an alphanumeric indication (14) that a change in the optical characteristic in the sample has been detected. The invention includes a uniquely configured sample cell (26) for receiving the samples of fluid to be tested and unique apparatus for delivering precise volumes of a liquid reagent. A liquid reservoir (194) is pressurized with gas to a preselected pressure and is automatically regulated to maintain the pressure at a constant value. A valve (176,178) in conjunction with a nozzle (192) and a conduit adapted to impart a constant flow rate to reagent being delivered is opened for precise, predetermined time intervals so that a precise predetermined volume of liquid flows through the valve in the predetermined time interval.

Abstract: For diversity reception from a plurality of antennas, particularly in an automotive vehicle (FIG. 4), the respectively received signals are mixed with a local oscillator signal to form a plurality of IF signals (u1 . . . un). The respective IF signals are weighted with a weighting coefficient which is derived from a sum circuit of all the IF signals, and the respective IF signal, which weighting circuit includes an integrator to minimize temporal variations in the amplitude of the sum signal. The sum signal forms the actual IF signal, for further processing, and demodulating to derive an audio signal. Preferably, the signals from the antennas are branched, and the branch signals phase-shifted 90 DEG , which, again, are weighted by similarly generated weighting coefficients, and the weighted, phase-shifted signals are combined in the adding or summing circuit (70) to form said eventual IF signal for demodulation.

Abstract: Disclosed are aligned plug optical fiber connectors that can accommodate larger differences in plug diameter and/or a wider range of plug diameters than is possible in prior art connectors, resulting inter alia in increased economy. The first of these advantages is attained through the use of bilaterally decoupled plug alignment means, i.e., means in which radial deformation of one half of the alignment means does not result in analogous deformation of the other half. A simple example of bilaterally decoupled alignment means is an alignment sleeve with a centrally located lateral slit. The second of the above advantages is attained through use of limited contact bilaterally decoupled alignment means, i.e., bilaterally decoupled alignment means shaped such that only a limited portion of the plug surface is in contact with the alignment means. A simple example of such alignment means is a transversely split alignment sleeve whose bore has roughly ellipsoidal cross-section. A preferred embodiment of the inventive connector comprises two cylindrical glass plugs (20 and 21), a glass alignment block (10) of L-shaped cross-section, and a bifuracted metal spring clip (14) that separately urges each plug against the two reference surfaces (11 and 12) formed by the arms of the alignment block. The presence of a recessed portion (13) of one of the reference surfaces is optional and can facilitate rotational tuning of the fiber connector.
