Abstract: A face protecting visor is provided for use when wearing optical devices h a helmet. A clear viewing portion of the visor is retained in the helmet by a bezel portion which extends structurally to bear against the outer surface of the helmet, thereby translating impact forces thereagainst to the helmet rather than the face. Included on the visor is one mating part of a catch mechanism located on the bezel portion for detachably affixing the optical devices thereto. Elastic members with snaps are also connected to the bezel portion for removably securing it to the helmet. A catch-stop mechanism on the interior of the bezel portion translates the gravitational loads of the visor to the helmet.

Abstract: The series wound, air core (SWAC) homopolar generator includes a pair of ls connected in series with a rotor having a pair of slip rings joined by conductive bars. To reduce eddy currents induced in the slip rings, their radius and axial length are chosen such that the circumferential and axial resistances of the slip rings fall in a bounded region wherein the axial resistance is minimized and the circumferential resistance is maximized.

Abstract: A fabric moisture detector and method is provided. The detector has a supt insulating structure, and a pair of electrodes, which have a pair of opposite faces separated by a gap of selective thickness, such as four inches or ten centimeters. The detector also has a current sensor, for measuring the current through the gap during the application of a relatively high voltage, such as about 10,000 volts to 60,000 volts for a ten centimeter gap. The voltage applied using a ten centimeter gap can be between about 1,000 volts per gap centimeter to 6,000 volts per gap centimeter. The process includes the steps of measuring the gap current during the application of the specified voltage, whereby a dry fabric or bare electrodes yields substantially no current and a wet fabric yields a peak current.

Abstract: A single-Schottky liquid crystal is disclosed in which a series of Schottky contacts are made on one side of a photoconductor substrate by a metal matrix mirror, with a doped semiconductor back contact electrode on the other side of the substrate. The light valve offers several operational advantages over MOS devices, and is easier to fabricate than double-Schottky light valves. It can be operated either in an AC mode or, by doping the liquid crystal ions, in a DC mode.

Abstract: Optical energy is conveyed through a region and is subsequently converted to electrical energy when it reaches the area of its intended use. Spatially multiplexed laser light is transmitted through an optical fiber to convey the energy through the area. Several light beams or several light beam paths may be used to convey a plurality of beams of light energy into an area either simultaneously or sequentially. Typically, two light beams enter the fiber at different angles of incidence, resulting in a first annulus of laser light that impinges on a first photocell and a second annulus of laser light that impinges on second photocell. This sequence continues alternately with the electrical outputs of the two photocells being coupled to a step-up transformer to provide electrical power for a system of interest, and or the energy being directed to a communication circuit for removing intelligence signals therefrom.
