Abstract: A method of and system for controlling a pipeline fluid parameter, including a main control valve (12) which is conditioned to open when upstream pressure (P 1 ) therein overcomes pressure (P j ) in a chamber (32) therein. The chamber is connected by load and bleed lines (34, 38) to a source of pressure and a low pressure zone, respectively, and normally closed control valves (40, 46) are provided in each of the lines. The valves (40, 46) are openable by solenoids in response to signals (40A, 44A) transduced from a fluid parameter for precise periods of time so that the valve chamber (32) is loaded or bled by small discrete volumetric increments of pressure fluid.

Abstract: In a method and apparatus for acquiring and recording an identification pattern from the reflectance of the fundus of an eye (36), a single light source (102) is operable to produce a substantially columnar source beam of infrared light directed into the fixated eye from a plurality of sequential, angularly divergent positions. The light is focused on the retina and reflected in part out of the eye. Variations in the ocular structure contribute to various reflected intensities. The intensity of the reflected light is detected, measured and recorded for each sequential angularly divergent position forming a unique and repeatable identification pattern, or "signature" for each individual.

Abstract: @ A nucleic acid hybridization assay wherein the hybrid formed with the probe has binding sites for two specific binding reagents, one of which comprises a first label and the other a second label, interaction of the first and second labels providing a detectable response which is measurably different when the two labeled reagents are both bound to the same hybrid compared to when the two labeled reagents are not so bound. The formation of the hybrid assay product brings the two labels within a proximate interaction distance of one another, e.g., as in the cases of sequential catalyst (enzyme) interaction and energy transfer. Since the labels provide a response which is distinguishable when they are associated with a hybridized probe, no separation step is required.

Abstract: A heterogeneous binding assay in which a liquid component and a granular particulate solid phase are incubated together for a predetermined period of time. The prevent unwanted unit gravity sedimentation of the granular particulate solid phase during incubation the density of the liquid component is controlled such that it is substantially equal to the density of the granular particulate solid phase, thus preventing sedimentation. The density may be controlled by adding a density modifying medium such as a colloidal suspension of silica particles coated with polyvinylpyrrolidine. After incubation, the density of the liquid component may be reduced allowing unit gravity sedimentation and hence separation of the solid phase from the liquid component. The assay is particularly applicable to immunoassay (for example radioimmunoassay and immunoradiometric assay). Immunoradiometric assays for human growth hormone, thyroid stimulating hormone and alphafetoprotein are described.
