Abstract: Applicants' Passive Radar Detector for Dualizing Missile Seeker Capability incorporates passive RF detectors into a standard active MMW seeker missile with a minimum requirement for hardware modifications. Anti-radiation homing (ARH) antennas and down conversion elements are added to the missile and coupled to existing signal-processing hardware. The added antennas intercept the air defense radar emission signals and the conversion elements convert the intercepted signals to the intermediate frequency (IF) usable by the MMW radar. The IF can then be processed by signal processor that already exists as a part of the MMW seeker.

Abstract: Rocket Accuracy Improvement Device, when coupled between the warhead and motor of a typical free flight rocket, isolates the warhead from the rocket motor in the axis using a plurality of ball bearings and thereby enables the warhead to spin independently of the motor. The separation of the warhead from the motor allows the angular momentum of the warhead, which has reached its maximum spin rate by the time the motor burns out, to act gyroscopically to maintain the trajectory of the rocket even when the motor reverses its spin, thus achieving a much more predictable flight path for the rocket.

Abstract: The fin lock system overcomes the major problems associated with the current deployment and locking mechanism by adding a center boss to the fin between the rear and front bosses and a sliding lock that engages between the housing and the center boss. The sliding lock, having a very low mass, engages with the center boss, and thus with the fin, very quickly and reliably when the fin reaches its fully deployed position, thereby arresting the motion of the fin and preventing it from rebounding. This, in turn, allows the aft-housing lug to lock the fin in its deployed position with one opening motion of the fin. The additional boss provides greater resistance to inertial and aerodynamic loads while the sliding lock completely eliminates both over-rotation of the fin and inconsistent engagement of the fin lock.

Abstract: A method process to convert inhibited red fuming nitric acid (IRFNA) and/or nitrogen tetraoxide to either dilute or concentrated (98%+) nitric acid. The method describes a process to remove all of the normal inhibitors (if required), that have been reported to been used in IRFNA. The process described will provide nitric acid free of contaminates which are undesirable when using the nitric acid in reactions to produce other products.

Abstract: The Remote Mosaic Imaging System having High-Resolution, Wide Field-of-View and Low Bandwidth (“Remote Mosaic System”) uses image frame synchronization and multiplexing to reduce the bandwidth needed to transmit the plurality of images to a remote location. The Remote Mosaic System employs a plurality of remote sensors to create a plurality of images. The use of readily available and inexpensive commercial imaging sensors significantly decreases the cost of the system while greatly increasing the capabilities of the imaging system to cover virtually any target space with virtually any desired resolution.

Abstract: The Rotational Canted-Joint Missile (RCJM) Control System utilizes a single or multiple body joints that rotate in planes that are not perpendicular to the missile body axis. The result is the deflection of a portion of the missile body for flight control purposes. The canted interface plane between any two adjacent movable sections of the missile body and a joint at the interface plane that allows one of the sections to be rotated by a pre-determined angle with respect to the other section comprise a rotational plane mechanism that offers an inclined bearing plane with a large mechanical advantage over typical “brute force” ball joint methods.

Abstract: Sets of coefficient polynomials are used to design embedded-component architectures that have capability for asynchronous parallel execution at an advantageous arithmetic level where algebraic merging is realized with other operations, algorithms or applications. Asynchronous parallel execution is use to produce image cross-correlation from a freshly-created target image and a pre-existing filter image. Arrays of pixels for both images are input to Cauchy registers where a correlation value is computed by obtaining the sum of all the individual products of corresponding pixels from the target image and the filter image. The cross-correlation value is obtained by the accumulation of each corresponding bit of the individual bit positions of each Cauchy product into a set of coefficient polynomials of the final cross-correlation value. The final cross-correlation value is input to a suitable tracking means to increase the level of accuracy and case in recognizing and tracking a potential target.

Abstract: In the monolithically integrated photonic circuit, light travels through multiple quantum well channel waveguides and is coupled into and out of the devices that reside in common on a single semiconductor substrate. Each device, which is co-planar with any other device on the substrate, is comprised of a quantum well channel waveguide of a pre-determined length and an electrical contact pad mounted on the waveguide that facilitates the application of electric field to the device. The function of any particular device as an optical source, an optical modulator or a photo-detector is determined by the bias mode of electric field applied to that particular device. The circuit is comprised of multiple rows of such devices. Each of these rows contains at least three devices which function as an optical source, an optical modulator and a photo-detector, respectively, and are separated from each other by electrical isolation gaps.

Abstract: The Collapsible Support Frame for Kinetic Energy Penetrator supports a long-rod kinetic energy penetrator inside a kinetic energy missile air frame in handling and flight environments but, upon impact of the missile on the selected high-obliquity target, gives way. This greatly reduces the lateral loading inflicted on the penetrator by the interaction of the missile body and the target and consequently maximizes the effectiveness of the penetrator against the target. The Collapsible Support Frame comprises concentric outer and inner rings that are mounted inside the missile and designed to hold and support the penetrator. When the missile strikes the target and the extremely high impact shock loading conditions of the penetrator process occurs, the outer ring captures a high impact shock loading pulse and transmits it to the inner ring, whereupon the inner ring fails in its supportive function, thus freeing the penetrator.

Abstract: The lightning rocket system of this invention comprises a rocket launcher that is in communication with a detection device that measures the presence of electrostatic and ionic change in close proximity to the rocket launcher that also fires the rocket launcher. This system is designed to control the time and the location of a lightning strike. The lightning rocket can be comprised of solid propellant that has cesium salts added which produces a conductive path when the exhaust gases are discharged from the rocket that is expelled to the static layer of a thundercloud. A conducting lightning rod which is grounded and positioned along side the launch tube for the solid propellant is in communication with the conductive path to thereby control the time and location of a lightning strike from the thundercloud. In a liquid expelled rocket a solution of calcium chloride is used to form a conductive path from a thundercloud.

Abstract: The Side-Scatter Beamrider Missile Guidance System projects into the guidance field a pulsed beam that is spatially encoded with azimuth and elevation scans of pre-determined angles. This pulsed beam is indirectly relayed to side-looking missile-borne receivers by way of scattered radiation effected by atmospheric particles. Multiple optical receivers mounted on the exterior of the missile, each receiver having a different field-of-view from its adjacent receivers, receive light from the transmitting laser that is thusly scattered by atmospheric particles. In response to the received scattered radiation, the missile's signal processor calculates the missile's position within the guidance field by determining which of the receivers detects the scattered energy and when the detection shifts from that receiver to an adjacent receiver.

Abstract: The interferometric alignment device is a small, compact device that can be attached to any two optical instruments that need to be aligned precisely in both pitch and yaw angles. The device utilizes light reflecting from mirrors that are permanently mounted inside the instruments, one mirror in each of the instruments. The reflected light beams exit their respective instruments via a window built into the frame of the instrument and re-enters the attached alignment device wherein they combine to form an interference pattern. The operator of the alignment device observes the fringes of this pattern and adjusts the azimuth and elevation of one instrument relative to the other instrument until the fringes are at an acceptable minimum number or are eliminated altogether.

Abstract: Sets of coefficient polynomials are used to design embedded-component architectures that have capability for asynchronous parallel execution at an advantageous arithmetic level where algebraic merging is realized with other operations, algorithms or applications. Because of the particular hardware structures made possible by the use of CPA, higher computational granularities and complex modules are more easily feasible than by using conventional arithmetic and, additionally, increased efficiency is obtained for algorithmic computations involving single and multiple operations. This is achieved by the merging of operations and the integration of algorithms, and thereby avoiding the necessity of performing the entire basic arithmetic separately for each operation or algorithm.

Abstract: The Magnetostrictive Missile Guidance System pivots the missile nosecone about a multi-directional joint on the missile axis to produce aerodynamic control forces for missile flight path control. The nosecone is driven by magnetostrictive materials in conjunction with displacement amplification devices. The determination of the nosecone deflection angle necessary to achieve any change in the flight path is made by a sensing device that produces position signals and a guidance computer that produces the desired flight path command signals. The sensing device senses the current position of the nosecone and this position signal is compared with the command signal by the computer to yield an error signal, which is indicative of the difference between the two input signals. Then appropriate magnetic field is applied to the magnetostrictive materials to cause them to grow in length and deflect the nosecone until the error signal is eliminated and flight path is changed.

Abstract: A steel projectile assuming the general shape of a teardrop compensates for the lower density of the material as compared to lead and still achieves penetration into the target that is comparable to spherical lead pellets. Additional benefit of the elongated exterior geometry of the projectile is less scatter and less aerodynamic drag during flight.

Abstract: In-Seeker Jamming Device, suitable for an RF missile, utilizes the high-gain antenna and amplifier that are already a part of the missile. During the “blind range” between the termination of the missile's active tracking of the target at a pre-selected distance from the target and its impact on the target, the Jamming Device produces signals that are broadcast via the missile's antenna and are designed to jam and frustrate the active protection system (APS) radars, thereby rendering the APS radars ineffective and the intended targets vulnerable.

Abstract: Parallel data busses are embedded in multiple parallel grooves that are inscribed onto the exterior surface of a rectangular substrate or a cylindrical substrate that has a cylindrical hole running through the center thereof. These grooves which run along the length of the substrate may contain a suitable polymeric optical medium such as plexiglass or lexan or left entirely vacant to be filled with air. Optical transceivers placed to be orthogonal to the data busses and reflective conical structures positioned within the busses expedite the injection and retrieval of optical signals travelling through the data busses.

Abstract: The Dynamic Bendloss Measuring Device allows easy, repeatable determination of the bend sensitivity of a single-mode optical fiber by subjecting the fiber to dynamically changing bend angles under varying degrees of tension and bend diameters. It utilizes a swing arm capable of sweeping an arc subtending a range of angles at any given bend diameter and fiber tension and calculating the bendloss from the light attenuation at each degree of the range. The varying bend diameters are provided by pins of diverse diameters that are singly inserted into an adjustably-sized aperture while the variation in the applied tension can be effected by changing the input current setting in the tension assembly. With each new pin and tension setting, the swing arm sweeps through the pre-selected range of bend angles, resulting in varying degrees of attenuation of light.

Abstract: The photonic band gap (PBG) dual-spectrum sensor utilizes the frequency-selective properties of a photonic band gap device constructed in accordance with this invention to separate incident electromagnetic wave into two frequency bands. The parameters of the PBG device are chosen so that one frequency band is transmitted through the device with low attenuation while the second band is reflected with low attenuation from the front face of the device. This separation of the two frequency bands allows separate detection processes to be performed to recover the information content of the two signals before the information is fused in subsequent signal processing operation. Such a PBG device would be useful in missile seekers that seek to distinguish a target object from its background.

Abstract: A Non-Protrusive Expandable Clamping Device fastens together two bodies when conventional fastening devices cannot be used because of the unique space constraints and/or the shape of the joining surfaces of the bodies. The expandable clamping device, which has two tenons on opposite sides of its housing, can be slid into the bodies that have corresponding mortises on their joining surfaces to accommodate the tenons. The clamping device connects the bodies in one linear plane using motion in an orthogonal plane. When the clamping process is completed, facilitated by the rotational motion of a threaded bolt within the cavity inside the housing, what results is a joint that is strong in all directions as well as flush and airtight between the surfaces when an appropriate gasket or O-ring is utilized. Such a joint ensures proper alignment of the bodies while providing fixity in six degrees of freedom.
