Ultra-Wideband Receiver
U.S. Patent 5,523,760
June 4, 1996
A single-ended ultra-wideband receiver with a self-regulating amplifier that maintains a predetermined average output voltage. An input channel is connected to one input of the amplifier and a strobe generator is connected to the input channel. A single Schottky detector diode or a pair of series-connected Schottky detector diodes are placed in the input channel.

Electrorheological Crystallization of Proteins and Other Molecules
U.S. Patent 5,525,198
June 11, 1996
The process of producing an electrorheological crystalline mass of a molecule by dispersing the molecule in a fluid and subjecting the molecule dispersion to a uniform electrical field for a period of time during which the electrorheological crystalline mass is formed. Crystallization is performed by maintaining the electric field after the electrorheological crystalline mass has formed, during which at least some of the molecules in the mass form a crystal lattice.

Fan-Fold Shielded Electrical Leads
U.S. Patent 5,525,760
June 11, 1996
Electrical leads that are shielded, vacuum- and cryogenic-temperature-compatible, totally nonmagnetic, and bakable. They are suitable for multiple signal and/or multiple layer applications, and the leads are suitable for voltages in excess of 1,000 volts. The assembly is easily fabricated by simply etching away certain areas of a double-clad substrate to form electrical leads on one side.

The Portable Gas Chromatograph-Mass Spectrometer
U.S. Patent 5,525,799
June 11, 1996
An organic chemical-analysis instrument that has sensitivity and mass resolution characteristics of laboratory benchtop units, but is portable and has low electrical energy consumption. The instrument weighs less than 32 kilograms and uses less than 600 watts at peak power. The instrument incorporates a modified commercial quadrupole mass spectrometer to achieve the instrument sensitivity and mass resolution, comparable to larger laboratory instruments.

Phosphate Glass Useful in High Energy Lasers
U.S. Patent 5,526,369
June 11, 1996
A laser system using phosphate laser glass components having an emission bandwidth of >26.29 nm and a coefficient of thermal expansion, from 20 to 300°ree;C of <145 ¥ 10-7/K. The laser glass components consist of a multioxide composition, Al2O3 for chemical durability and thermal mechanical properties, and K2O. The system operates at an energy level of <0.1 MJ. The glass is desirable for laser operation and manufacturing.

High Energy Bursts from a Solid State Laser Operated in the Heat Capacity Limited Regime
U.S. Patent 5,526,372
June 11, 1996
A heat-capacity laser operating in two modes: a firing cycle and a cooling cycle. In the firing cycle the solid-state laser is not cooled. In heat capacity operation, as lasing proceeds, the active medium will heat up until it reaches a maximum acceptable temperature. The waste heat is stored in the active medium itself. After lasing is complete, the active media are cooled to the starting temperature, and the laser is ready to fire again.

Carbon Foams for Energy Storage Devices
U.S. Patent 5,529,971
June 25, 1996
A double-layer capacitor of carbon foam electrodes. Several foams may be produced-including aerogels, xerogels, and aerogel-xerogel hybrids-that are high-density, electrically conductive, dimensionally stable, and machinable. The electrodes are formed from machinable, structurally stable carbon foams derived from the pyrolysis of organic foams. Integration to form the capacitor is achieved using lightweight components.
