Abstract: Embodiments of the present invention concern locating targets using non-linear radar with a matched filter which uses exponential value of the transmit signal. According to embodiments, a method of non-linear radar target location includes: transmitting a signal of a transmit waveform towards a target; receiving a signal from the target; creating a matched filter by generating an exponential function of the transmit waveform corresponding to a particular harmonic of the interest; and applying the matched filter to the received signal to generate and output a signature waveform for the target of the particular harmonic of interest. In other embodiments, the matched filtering may be combined with sidelobe reduction.

Abstract: A photodetector comprising a contact layer; an absorbing region positioned such that light admitted passes into the absorbing region; a diffractive region comprising at least one diffractive element operating to diffract light into the absorbing region; the configuration of the photodetector being determined by computer simulation to determine an optimal diffractive region and absorbing region configuration for optimal quantum efficiency for at least one predetermined wavelength range, the diffractive region operating to diffract light entering through the contact layer such that phases of diffracted waves from locations within the photodetector including waves reflected by sidewalls and waves reflected by the diffractive elements form a constructive interference pattern inside the absorbing region. A method of designing a photodetector comprises using a computer simulation to determine an optimal configuration for at least one wavelength range occurring when waves reflected by the diffractive element form a constructive interference pattern inside the absorbing region.

Abstract: A flechette for use with a gun barrel having a tapered bore with a diameter at the initial bore section greater than the diameter at the emergent bore. The flechette includes a body constructed of a ductile material and having an elongated axis aligned with the axis of the tapered bore when positioned in the load end of the bore. The body also includes a cylindrical bulkhead as well as a bourrelet that are axially spaced from each other along the flechette and have an outside diameter substantially the same as the diameter at the initial bore section of the tapered bore. An elongated boom is attached at the tail end of the body while a penetrator is attached at the forward end of the body. Upon launch, both the bulkhead and bourrelet are compressed radially inward by the bore reduction so that the body is substantially cylindrical upon exit from the discharge end of the bore.

Abstract: Methods of adjusting the mechanical properties of a polymeric material may include forming a polymer network having a plurality of permanent cross-links and coupled to a plurality of reversible cross-links, wherein the polymer network has a shear storage modulus of greater than about 4×104 Pa; and heating the polymer network using a heat source to dissociate the reversible cross-links, wherein heating the polymer network reduces the shear storage modulus to less than about 4×104 Pa. In some embodiments, a polymeric material may include a polymer network comprising a plurality of permanent cross-links and coupled to a plurality of reversible cross-links that are dissociable with the application of a stimulus and associable with the removal of the stimulus, wherein the shear storage modulus of the polymer network is less than about 4×104 Pa in the presence of the stimulus and greater than about 4×104 Pa in the absence of the stimulus.

Abstract: A system for detection of human or vehicle activity comprising at least one sensor adapted to generate a signal and at least one processor operating to denoise the signal; generate an autocorrelation of the signal; partition the signal into a predetermined number of overlapping segments to form a time series of data; generate symbols for the overlapping segments; compare the pattern of generated symbols with known predetermined patterns of symbols representing human or vehicular activity; determine whether a threshold probability is exceeded which attributes the data signal to human or vehicular activity; analyze the patterns presented in the data signal by transforming the patterns of symbols into states; determine the transitions between states; and classify the signal as to being attributable to human or vehicular activity based upon the transitions between states. A method of detection and classification of sensor data signals via detecting patterns using time series analysis.

Abstract: Embodiments of the present invention relate to power line detection, and more particularly, to methods and systems for autonomous power line detection, avoidance, navigation, and inspection. They may be implemented using aerial crafts, but do not have to. According to an embodiment, a method for detecting energized power lines in ambient space in the vicinity of an aerial craft is presented. The method includes measuring, with sensors located on the aerial craft, electric and magnetic fields in the space; and with a power line detection controller, detecting an energized power line in the space in the vicinity of the aerial craft using the sensor data; and determining the orientation of the detected energized power line in the space based on the electric and magnetic field measurements. Similar methods and systems are also presented.
