Abstract: A pair of matched filters describing a pre-selected category of objects is ade, each of the filters having a center located at a unique place in the filter. When incorporated into a MACE filter and used in an optical correlator, a line drawn through the correlation peaks caused by the centers of the matched filter pair and a pre-selected axis together produce an angle that is indigenous to that particular category of objects, thus identifying the category of objects.

Abstract: The retro-encoded guidance system guides a flying object in its flight tod its destination by measuring and correcting the angular displacement of its actual trajectory from the straight line-of-sight to the destination. A beam of infrared light emanating from a beacon on the flying object is received and angularly encoded by retro-encoder located at the launcher prior to being returned to the missile. The incident beam and returned beam travel on optical paths that are parallel to each other but opposite in direction. The angular encoding is achieved by a reticle of the retro-encoder imparting frequency modulation to the incident beam, the degree and phase of the modulation depending on the location on the reticle on which the beam is incident.

Abstract: To remove excess heat from the fin of a flying object that is driven by a opulsion means, heat pipe principle is integrated into the structure of the fin. The heat from hot exhaust gases that flow over the evaporator section of the fin is absorbed by a working fluid within the fin, such as water, which then vaporizes. The resulting vapors flow to the condenser section of the fin where it releases the heat to the ambient air that flows over the condenser section. As heat escapes into the ambient air, the vapors condense, becoming a liquid again. The liquid travels back to the evaporator section where the heat absorption/vaporization process is repeated.

Abstract: In a phased array radar, simultaneous beam steering and single-sideband mlation is accomplished in the phase shifters in response to phase control signals produced by the beam steering controller and input to the phase shifters. The beam steering controller produces the phase control signals from a pre-selected beam steering angle, a pre-selected radar intermediate frequency and a voltage representing the frequency error from incomplete compensation of the target motion (doppler) of the previous cycle of the radar. Using the phase shifters thusly eliminates the need for an expensive separate component, the single sideband modulator.

Abstract: The wing deployment device is a simple mechanical device that resides in hollow of the wing and combines a primary and a secondary rotational motions to translate the wing from its stored position to its deployed position. The primary rotational motion occurs when the initial restraint holding the wing to the missile body is severed and the wing, under the influence of the spring component of the device, rotates to a position normal to the missile body axis. After the lapse of a pre-determined duration of time, the secondary rotational motion is started when the tensile force of the spring is transfered to the swivel component via the kevlar rope coupled between the spring and the swivel. As the kevlar rope that is wrapped around the cylindrical shaft component unwinds, the swivel rotates and transmits the rotational motion to the base component which is rigidly coupled to the wing and, in turn, imparts the motion to the wing, thereby engaging the wing in the secondary rotational motion to be deployed.

Abstract: The invented methods provide a means for reducing or eliminating manual astments that are required during the fabrication (winding) of fiber optic dispensers. This reduction is accomplished through the use of a fiber placement pattern that is permanently generated on the bobbin winding surface. Filaments, such as optical fibers, are precisely guided during the winding of subsequent filament layers by the embedded crossover pattern baselayer. The embedded crossover pattern baselayer is generated by first winding in a given direction a wire of a pre-selected diameter upon the polymer coating on the bobbin surface. The polymer is allowed to cure partially before the wire is unwound and removed. Afterwards a pre-selected optical fiber is wound in the direction opposite that of the wire winding direction thereby creating crossover patterns which are, then, manually adjusted to be in desired locations on the bobbin axis.

Abstract: The spinning mine has all of its projectiles concentrated in one small ar It is launched from a spring-loaded threaded screw launcher and acquires angular momentum as it ascends into the air from the launcher to a pre-determined detonation altitude. As the mine spins, the detector assembly on board detects the presence and location of potential targets and sends appropriate indicative signals to a microprocessor, also on board. The microprocessor determines therefrom the location of the largest target or the largest cluster of targets in the environment and triggers the detonation of the mine such that the projectiles are jettisoned in a conical pattern toward the largest target or the largest cluster of targets for a more efficient destruction of the targets.

Abstract: An Identification-Friend-or-Foe System Using Variable Codes (IFF System) lizes variable codes and pre-selected encryption/decryption technology to querry potential targets as to their battlefield affiliation and also to identify itself as a friend to a potential attacker. The IFF System performs a querry by sending a narrow laser beam to the potential target which is accompanied or closely followed by a radio frequency (RF) wave modulated with encrypted identification information. If the potential target is also equipped with the IFF System and in possession of the valid code, then the received RF wave can be decrypted to reveal the potential attacker as a friend. The potential target, then, encrypts its own identification information using the same code and transmits it via RF wave to the potential attacker. Thus fratricides may be avoided.

Abstract: Reduction of the surface friction of a cured elastomer, sealant or adhesive s accomplished through the use of a dry lubricant such as hexagonal boron nitride powder either as an additive to the uncured polymer mix or applied to the uncured polymer surface prior to effecting a cure.

Abstract: The Nutated Beamrider Guidance Using Laser Designators provides a means of roducing an accurate laser beamrider command guidance link between the launch platform and the missile during its flight through the addition of a simple variable offset nutator mechanism to existing Army laser designators. Such a beamrider guidance enables the missile to determine its position in the guidance field by measuring the angle of arrival of side scatter from the pulsed beam. These measurements result in the production of correctional signals which cause the missile to move closer to the boresight axis for eventual impact on the target.

Abstract: The pulse-coupled automatic recognition system processes information utilizing parallel neural network and transmits information to and from the processing sites as time signals which encode in their pulse phase structure the geometrical content of the spatial distributions of light. A locating device then measures the coordinates of the spatial distributions (pulsating segment) and displays the coordinates of the pulsating segment on a screen for observation. The pulsating segment indicates the presence and location of the component of the input scene that corresponds to the segment.

Abstract: The off-axis joint transform correlator improves on the extant on-axis jo transform correlator by eliminating the requirement for a second laser frequency and the means for blocking the first laser frequency from propagating beyond a given point in the correlator. These eliminations are accomplished by using a beamsplitter and a mirror to bring a second portion of the first frequency at an angle to read the pattern information written onto a spatial light modulator by the first portion.

Abstract: The fiber optic-based correlating and sensing system (the System) utilizes length of optical fiber through which the object beam travels prior to being incident on the holographic plate. First, a matched filter is created on the holographic plate of the initial condition of the environment. Then when the plate is re-placed in its original position in the System and the reference beam is blocked from reaching the plate, a correlation peak appears as the object beam passes through the holographic plate. To use the System as a correlator, the object beam is transmitted through an input scene prior to its travel through the optical fiber. The changes in the input scene from the initial scene causes broadening of the shape of and degradation of intensity of the correlation peak. To use the System as a sensor, the object beam travels through the optical fiber acquiring information regarding the environment surrounding the fiber, such as pressure, temperature, sound, electric and magnetic fields.

Abstract: An LCD projection system, located within a standard color CRT, is used to oject toward the screen decay stimulation patterns that vary dynamically from one frame to the next for each pixel based on the video signals received from external sources. This controls the output light intensity of the phosphors that are excited by a single electron gun. This system eliminates the three-electron-gun configuration of the standard CRT as well as the requirement of a shadow mask. What results is a CRT that is more rugged, easier to manufacture and that produces brighter and sharper images on its screen.

Abstract: The Consistent-Force Quick Latching System (CQLS) provides a means for athing and detaching two objects quickly, using consistent force regardless of the dimensions of the individual objects. The CQLS, usually secured to object A, utilizes a notched cam and a detent that enters one of the notches in response to externally applied pressure and rotates the cam in conjunction with the rotation of a handle that is pivotally coupled to the cam. When the handle rotates in one direction, the cam rotates so as to raise the hook that is also pivotally coupled to the cam, thereby forcing against object A object B that has been slid onto the hook. The two objects are separated from each other by a release mechanism that pulls the detent out of a notch, allowing the handle to rotate in the opposite direction. This lowers the pivot point and thus the hook, resulting in separation of object B from object A.

Abstract: A new optical diode is disclosed that permits unidirectional transmission of light, the direction of transmission depending on the direction of incidence. The diode comprises a stack of alternating layers of a low-index material and a high-index material. The layers are arranged within the stack such that there is spatial anisotropy of optical pathlengths in the stack and at least the low-index layers or the high-index layers have an optical nonlinearity, either inherently or by doping. At sufficiently high incident intensifies and appropriate wavelengths, such a diode exhibits partial transmission of input light incident from one direction while reflecting almost totally input light incident from the opposite direction.

Abstract: A Reduced Radar Cross-Section RF Seeker Front-End interrogates a potential arget by issuing interrogation radiation toward the target and receiving and analyzing a portion of the radiation that reflects back from various surfaces of the targeted object while, at the same time, the Front-End reduces the likelihood of its own discovery by the enemy. The Front-End accomplishes the reduction by absorbing radiation directed toward it by an enemy radar or anti-tactical missile rather than allowing the radiation to be reflected back. Such absorption greatly diminishes the availability of signature reflection that belligerents rely on to identify hostile forces on the battlefield.

Abstract: A potential target scenery image data is filtered and complex-multiplied h synthetic discriminant functions to produce a two-dimensional, cross-correlated surface. The surface is then analyzed to determine the spatial coordinates of the target, if any.

Abstract: A breech assembly similar to a modified shotgun breech is used to fire gaus combustion products from a shotgun type pyrotechnic cartridge into a tank that holds the compressed gas. This compressed gas can then be used to drive power tools, inflation assemblies or any device which normally operates on compressed air.

Abstract: A lightweight telescopic lens of monolithic construction is revealed that corporates additional refractive and reflective curved surfaces to produce all the optical functions performed by an ordinary telescope. A pair of such lenses may be mounted in an eyeglass frame to yield a telescope that can be worn like a pair of eyeglasses, thus affording superior image stability as well as free the user's hands. Minor modifications involving the use of several menisci of a different index of refraction from that of the core lens can be made to achieve achromatism of emergent light from achromatic input light. The entire core lens can also be shaped into a meniscus to take advantage of the principle of total internal reflection, thereby increasing the light-gathering aperture while at the same time rendering the lens even more compact and lightweight.
