Title: Methods for providing internal references for use in analyte-receptor assays
Inventor: VALKIRS GUNARS E
IPC: G01N33/543
Filed: 1987-03-20
Granted: 1991-07-30
Abstract: Abstract A method is disclosed for providing internal references for use in an analyte-receptor assay, for the determination of a target analyte in a sample.  The assay uses a signal producing system and an analyte receptor capable of binding the target analyte at a discrete test zone on a solid phase, in an amount directly proportional to the amount of target analyte in the sample.  The method comprises binding a reference receptor, selected to bind with an analyte receptor conjugate capable of complexation with the target analyte, at a discrete reference zone on a solid phase. The reference receptor is selected such that the rates of binding of the analyte receptor conjugate to the reference receptor and to the target analyte are direct-ly proportional to the amounts of reference receptor at the reference zone and target analyte bound at the test zone on the solid phase, and the rate constants are substantially equivalent.

Abstract: "USE OF A CYCLODEXTRIN-ENHANCING SOLUTE IN THE HYDROLYSIS OF STARCH FEEDSTOCKS"                          ABSTRACT           The yield of cyclodextrins formed in the hydrolysis of starch catalyzed by a cyclodextrin glycosyltransferase can be substantially increased by the addition of certain water-soluble solutes.  Alcohols containing 1 to 6 carbon atoms form one such class, with ethanol and isopropyl alcohol being especially effective.  Where an immobilized cyclodextrin glycosyltransferase is used yields of beta-cyclodextrin can be increased from approximately 20% to almost 40% using 15% isopropyl alcohol in a thinned starch feedstock, with glucose production being increased by only about 25%.

Title: Velocity reference system
Inventor: STRATTON KENNETH L
IPC: G01S15/58
Filed: 1988-11-22
Granted: 1991-10-08
Abstract: Abstract A velocity reference system uses a Doppler shift between transmitted and received wave energy to determine the relative speed between the system and a surface or element.  Other systems employing Doppler shifts for detecting velocity suffer from poor measurement accuracy.  Cross talk between channels of systems having multiple transmitters and receivers produces measurement errors.  Additionally, errant movement generates measurement errors since the sensors cannot distinguish such errant movement from forward velocity.  Two sensing units directed towards one another, and preferably towards the same location on the surface, effectively eliminates random vehicle movement.  Furthermore, transmitting different frequencies from the two sensing units reduces cross talk between the two channels.  Vehicle applications require a system capable of minimizing errant movement and environmental noise.
