Abstract: Provided herein are methods for discovery of epitope specific monoclonal antibodies to pathogens directly from immune sera for immunotherapeutic use. Further provided herein are methods to determine molecular structure of antibodies targeting an antigen from convalescent or vaccinated individuals for the purpose of rational vaccine design.

Abstract: An antenna receiving system having an array of dual sense antenna elements for receiving both right hand and left hand circular polarized radiation from each of one or more targets, a right hand and a left hand polarized radiation attenuator and a right hand and a left hand polarized radiation phase shifter connected to each antenna element, a direction finding computer for controlling the attenuators and phase shifters connected to each antenna element and for processing outputs from selected pairs of phase shifters in order to find a direction to each of the one or more targets, and a beam forming computer for control the attenuators and phase shifters in order to select a cluster of antenna elements for each of one or more targets, each cluster for receiving data from a target.

Abstract: A power delivery apparatus and method which calibrates a voltage delivered from a central unit to a remote unit to compensate for losses in the supply lines between the central unit and remote unit is disclosed. The impedance of the supply lines is determined utilizing a reference voltage conducted by a calibration line, a sweep tone transmitted down the supply line, or a time domain reflectometer technique. Based upon the determined impedance of the supply lines, the voltage delivered from the central unit can be calibrated accordingly. Alternatively, the impedance can be determined and the voltage calibrated based on the measured input voltage to the remote unit or the measured power level of a signal transmitted from the remote unit.

Abstract: A method for improving the linearity of a signal coupling device having a ferrite core transformer comprises the step of demagnetizing the ferrite core. The resulting signal coupler has substantially zero remanent magnetism.

Abstract: An improved water flotation release device for locating the submerged position of ships that have sunk. The device comprises an improved release buoy that is self contained and communicating and a releasing system that leads to non-violent and reliable release from the sinking ship.

Abstract: Pairs of input transducers are formed on the surface of a piezoelectric crystalline body. The input transducers in each pair produce adjacent parallel surface acoustic waves of opposite polarity and specific phase difference which are sensed by a corresponding output transducer. The input transducers of each pair are offset from one another by amounts related to the wavelength of the surface acoustic wave so that a maximum cancellation of the voltages induced in the output transducers by the acoustic waves can be used to indicate the relative delay or phase difference of signals applied to the input terminals and to do so in a manner which is insensitive to temperature variation from one point to another in the piezoelectric crystal.

Abstract: A sensor formed on the surface of a body of piezoelectric material. Two input transducers disposed on the surface in parallel spaced apart relation produce surface acoustic waves in the body in response to the application of signals to the input transducers. A row of output transducers is disposed on the surface between the input transducers. Individual output transducers are offset from one another by amounts related to the wavelength of the surface acoustic wave so that at or near only one of the output transducers will the two surface acoustic waves from the input transducers cancel each other. An analog circuit and a digital circuit for ascertaining which output transducer experiences maximum cancellation to afford a determination of the delay difference between the two signals applied to the input transducers.
