Abstract: ABSTRACT           A unitary optical guidance system and apparatus directs operators of vehicles such as airplanes, water-craft, trucks, and automobiles along a path or to a predetermined location (e.g., parking an aircraft at a terminal gate or landing an aircraft on a runway) with a high degree of accuracy.  The apparatus projects one or a plurality of different colored rays of light in separate and substantially parallel colored light lanes.  Light from the apparatus generally is directed at an incident angle with respect to the operator of an approaching vehicle such that upon proximity of the vehicle to a predetermined location, one of the colored lanes of light will be seen by the operator.  Where multiples lanes of light are projected, the initial lane color may be tra-versed until a final lane color is encountered indica-ting that a desired or predetermined location has been reached.  A directional indicia media having one type of indicia to indicate a lateral approach position of a vehicle and a second type of indicia to indicate the distance of the vehicle from a predetermined location may be utilized with one or more lanes of light.

Abstract: ABSTRACT OF THE DISCLOSURE          A precision approach control system designed to control the approach of an aircraft during landing to provide a more stable and easier mode of landing during critical landing situations, such as during the landing of an aircraft on an aircraft carrier.  During operation, when the aircraft is subjected to vertical or horizontal winds or wind shear, the system controls the aircraft to maintain the inertial flight path angle constant which essentially defines operation in the precision approach control mode.  In one disclosed embodiment, the precision approach control system changes the controller in the cockpit that is normally the pitch rate command stick controller during a Power Assist landing into a flight path angle rate controller. The autothrottle system for the aircraft is utilized to maintain the aircraft at a predetermined angle of attack during landing in the precision approach mode.

Abstract: An analytical method for determining the relative amount of a particular hemoglobin derivative, e.g., glycated hemoglobin, in a blood sample wherein the amounts of both total hemoglobin and the hemoglobin derivative are measured and related mathematically, e.g., as a percentage. The blood sample is treated with the combination of a thiocyanate salt and an oxidant to denature the hemoglobin in the sample and to convert hemoglobin to met-hemoglobin. Met-hemoglobin is measured spectrophotometrically to give the amount of total hemoglobin present, and the denatured hemoglobin derivative can be distinguished and measured by immunoassay. The presence of the oxidant in the denaturant solution has been found to increase the rate of denaturation of hemoglobin thereby reducing the overall assay time and improving the reliability of the determination.
