Abstract: A method of organizing a radar system or a sensor system with multiple levels of hierarchical constructs for all level of the system. These architectural levels incorporate self-similar organizational structure and represent design strategies that implement data transfer and communication interfaces with both intranet and internet communication network connections.

Abstract: A method for remotely detecting whether a subject is alive, comprising the steps of determining a calibration spectral signature for light reflectance from living skin, normalizing the calibration spectral signature values to the calibration reflectance value at a reference wavelength, storing the normalized calibration spectral signature, determining a subject spectral signature of the light reflectance of a region of skin of the subject whose liveness is to be determined, normalizing the subject spectral signature values to the subject reflectance value at the reference wavelength, comparing the normalized subject spectral signature with the normalized calibration spectral signature for at least one wavelength, generating a subject liveness signal based on the comparison of the normalized subject spectral signature with the normalized calibration spectral signature, and emitting the subject liveness signal.

Abstract: A method of spraying an aerosol spray, comprising providing a grounded nozzle and an electrode separated by a predetermined distance; placing the electrode at a high electrical potential relative to the nozzle, thereby creating an electric field between the nozzle and the electrode; ejecting a liquid from the nozzle towards the electrode to atomize the ejected liquid into aerosol droplets or particles, so that in the applied electric field between the nozzle and the electrode the aerosol droplets or particles obtain an induced electric charge; and forming a directed spray of aerosol droplets or particles having a desired shape and with sufficient momentum and electric charge so that the directed spray of aerosol droplets or particles is deposited on a target.

Abstract: The invention is method for tracking moving objects from data by tracking a cluster of resilient features of the target. The features correspond to a set of trackers, to maintain tracking or allow rapid reacquisition and subsequent tracking although the objects' form and geometry may change. The method includes a Motion Fields Extraction step, a Creation of the Elastic Matrix step, and a step including the recurring tracking of the target. The Motion Fields Extraction step further includes generating Candidate Matches, Localizing Motion Voting, and Resolving Voting, and the Creating the Elastic Matrix step includes the steps of Creating the Candidate Targets, Assessing the Target Quality of the Candidate Targets, and Creating the Elastic Matrix.

Abstract: A process of extracting halogenated organic compounds, and particularly PCBs, from soil, sediment, slurry, sludge and dehalogenating the compounds contacts a contaminated soil sample with an extraction medium of a mixture of an alkane and a water miscible alcohol. The organic compounds dissolve in the extraction medium which is separated from the soil by passing water upwardly through the soil. The extraction medium floats to the surface of the water and is separated. Thereafter, the extraction medium containing the halogenated organic contaminants is subjected to ionizing radiation to radiolytically dehalogenate the compounds.
