Abstract: LAYERED IMMUNOASSAY USING ANTIBODIES BOUND    TO TRANSPORT PARTICLES TO DETERMINE      THE PRESENCE OF AN ANTIGEN                 ABSTRACT OF THE INVENTION          A device is provided for determining the presence of an antigen which comprises a trapping zone, which contains material capable of capturing free flowing enzyme linked antibodies, but not antibodies bound to a transport particle which flows freely through the trapping zone into the substrate zone, and a substrate zone which contains material capable of reacting with enzyme-linked antibodies to produce a reaction which indicates the presence of antibodies.  A method of determining the presence of an antigen is provided wherein a sample is mixed with two classes of antibodies which are specific for the antigen being tested for, but which react with different antigen domains, wherein the mixture consists of class one antibodies bound to a transport particle which flows freely through the trapping zone and class two enzyme-linked antibodies which are incapable, unless bound to the transport particles, of flowing freely through the trapping zone.  In the presence of the antigen being tested for, both classes of antibodies bind to the antigen and flow through the trapping zone into the substrate zone, wherein a reaction takes place to indicate the presence of the antigen.

Granted: 1991-09-03
Abstract: SCULPTURE APPARATUS FOR CORRECTING      CURVATURE OF THE CORNEA                 ABSTRACT OF THE DISCLOSURE      In the context of ultraviolet-laser sculpting of the cornea to achieve optical correction through a newly shaped anterior surface, the invention subjects the laser beam to certain shaping and homogenizing operations prior to any attempt to specially characterize the beam for a particular sculpturing procedure.  In a preferred embodiment, the shaping and homogenizing operations present a tolerably homogeneous beam of enlarged dimension, so that specialty-characterizing may proceed on a dimensional scale that  s greater than the corres-ponding dimension of ultimate surgical delivery to the eye, thereby enabling greater control of the quality of specialty-characterizing,  Provision is made for selectively monitoring the-quality of the homogeneity and/or of the specially-characterized beam, with further provision for automated cutoff of laser beam delivery to an eye in the event that quality is not within predetermined limits of tolerance.  And preferably, all beam shaping, homogenizing and character-izing operations proceed in a controlled environment which precludes ozone development and thus minimizes the beam-degrading effect of ozone and particulates or other contaminants.

Title: Absolute position sensor using multiple wavelengths of offset pitch phase patterns
Inventor: AUCHTERLONIE RICHARD C
IPC: G01B7/14
Filed: 1988-05-27
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE      For enabling a resolver to have absolute position sensing over a wide displacement range while still obtaining the resolution, accuracy and precision obtainable by operation in an incremental mode, the resolver is provided with a number of terminals for providing offset pitch phase indications as a function of position.  A microcomputer is programmed to execute a decoding procedure for reading the offset pitch phase indications and from them computing the absolute position.          This method is applicable to linear as well as rotary position sensing.  By using multiplexing, digital signal processing and large-scale circuit integration for interfacing the resolver to the microcomputer, the method can achieve absolute position sensing with high reliability and low cost.  The offset pitch phase indications are readily provided by inductive coupling between a multiplicity of windings, including a set of offset pitch windings connected to the terminals.   A phase indicating signal is picked up using either a relatively moving pick-up device or a stationary coil linked by a ferromagnetic core.  A  radio-frequency powered modulator is provided for wireless transmission of the phase indicating signal from the moving pick-up device.  The offset pitch windings are formed by photolithography on a plurality of laminations or layers, or by winding coils in proper registration, for example, on a multi-layer, multi-pitch coil form.
