20120133549Active Electronically Scanned Array Antenna for Hemispherical Scan Coverage - An antenna architecture for hemispherically-scanning active electronically scanned arrays (AESA). The antenna architecture utilizes variable diameter disks of antenna elements configured in a conical implementation. The antenna elements are oriented such that the element boresight is normal to the surface of the conical structure. Beamforming takes place on each disk first, and them separately in combining the signals from each disk, thereby reducing complexity. The antenna optionally utilizes disks of antenna elements of the same diameter to form a cylindrical antenna, which when combined with a conical configuration create enhanced sectors while maintaining a hemispherical coverage capability. Further, use of two conical configurations can produce a fully spherical coverage capability.05-31-2012
20120084249METHOD FOR POLLEN-BASED GEOLOCATION - A method for pollen-based geolocation. The method determines the probability P that a given location is part of the travel history of a given sample. Using simulated datasets and Monte Carlo simulation, the model parameters can be precisely associated with P, thereby allowing the algorithm to operate on real-life samples of interest.04-05-2012
20120063084CIRCUIT BOARD CHASSIS AND METHOD INCLUDING SIDEWALL APERTURE AND BACKPLANE INSERTION SLOTS FOR SIDE ASSEMBLED BACKPLANE - A circuit board chassis and a method for assembling a backplane and a circuit board into the circuit board chassis include an aperture within at least one sidewall of the circuit board chassis. The backplane is inserted and assembled into the circuit board chassis through the aperture (that may include a counter-opposed pair of backplane insertion and assembly slots) in a first direction, and a circuit board is inserted and assembled into the circuit board chassis and the backplane in a second direction perpendicular to the first direction. By inserting and assembling the backplane into the aperture and slots, rather than assembling the backplane as an external surface component of the circuit board chassis, the embodiments provide for ease of replacement of the backplane and circuit board under space constrained limitations. The resulting embodiments also provide enhanced rigidity and enhanced thermal dissipation within the circuit board chassis.03-15-2012
20120034699NUCLEIC ACID-LABELED TAGS ASSOCIATED WITH ODORANT - A nucleic acid tag comprising a nucleotide-support platform attached to a nucleic acid molecule, an odorant, and an encapsulant. Unique nucleic acid-containing tags containing an odorant are seeded at one or more geographic locations. Using odorant-detection systems, the person or object of interest is examined for the presence of one or more of the odorant, thereby revealing the presence of the seeded nucleic acids and eliminating the expense and time associated with unnecessary screening. The geographic location associated with each detected nucleic acid is used to backtrack the item's path or extrapolate a probable point of origin.02-09-2012
20110306141Location Analysis Using Fire Retardant-Protected Nucleic Acid-Labeled Tags - A nucleic acid tag comprising a nucleotide-support platform attached to a nucleic acid molecule, a fire retardant, and an encapsulant. Unique nucleic acid-containing tags containing a fire- or heat-protective element are seeded at one or more geographic locations. Using sequence analysis techniques, the person or object of interest is examined for the presence of one or more of the seeded nucleic acids.

20110270901Method and System for Bit Stacked Fast Fourier Transform - An FFT algorithm that splits a large bit width waveform into two parts, making it possible to conduct the FFT with much lower logic resource consumption is disclosed. The waveform is split into its most significant bits and its least significant bits through division in the form of a bit shift. Each partial signal is then put through an FFT algorithm. The MSB FFT output is then right bit shifted. The two partial FFT's are summed to create a single output that is largely equivalent to an FFT of the original waveform. Rounding distortion is reduced by overlapping the MSB and LSB partial signals.11-03-2011
20110268199Embedded Communications Capabilities for Radio-Controlled Improvised Explosive Device Force Protection Systems - A method and system for embedded communications that allows for FFT/IFFT-capable radio-controlled improvised explosive devices (“RC-IED”) force protection systems to communication information across local networks to enhance force protection operations and to provide additional data capacity to support other tactical operations. The communications system utilizes a significant amount of existing system hardware and software such that the addition of these communications capabilities does not significantly affect the unit cost of the RC-IED force protection system within which it is embedded.11-03-2011
20110267218System and Method for Reduction of Point of Origin Errors - A method of using a discriminant analysis and Kalman filter cascade to improve the accuracy of point of origin solutions. Tracking information about a potential target is utilized by an initial discrimination function to classify the target as a projectile. Using that information, the output of a first Kalman filter is fed into an additional discrimination function to further classify the type or sub-class of the projectile. A second Kalman filter can employ type-specific information to obtain a point of origin solution with increased efficiency and accuracy.11-03-2011
20110219037High-Performance Persistence Framework - A high-performance object database wherein an application fetches an object from a database and the high-performance persistence framework constructs the object in memory. The database is programmed with a class that allows the application to selectively activate objects referenced by the class rather than automatically activate all referenced objects. The application selectively activates these referenced objects using read or write methods depending on whether the objects will be modified. Upon completion of the transaction, only those objects that were modified are written to disk. This high-performance persistence framework provides an object database capable of storing a large number of interconnected objects on disk and accessing them without having to activate all of the connected objects while simultaneously indexing the objects in a large number of independent dimensions all at once for fast data retrieval with complex queries.09-08-2011
20110219016Stream Mining via State Machine and High Dimensionality Database - A system and method for stream mining using state machines and high-dimensionality databases. After a data stream is digitized, a stream analyzer searches a high-dimensionality data structure containing state machine parameters to determine which state machines to activate and execute. A signal classifier creates the state machine parameters stored in the high-dimensionality data structure using a second high-dimensionality data structure programmed with information about signals of interest. If a state machine identifies a signal of interest, the system can optionally alert the user.09-08-2011

20110205120Monopulse Beamformer for Electronically Switched Antennas - A method and system for monopulse beamforming for electronically switched antennas is presented. Inputs of selected antenna elements from a phased array antenna are summed into subsets of elements which are then combined into sum and delta beams. 2:1 switches in a shoelace arrangement allow the combination of signals from half of the selected aperture first at common phase and then at pi phase difference to from the sum and delta beams. The method allows for reduced weight, controls, and processing when compared to prior art.08-25-2011
20110054961Adaptive Risk Analysis Engine - A method for characterizing risk using an adaptive risk analysis engine. Following a user request for a risk analysis, online and/or offline factual information is retrieved by the engine and is used to produce risk indicators.
