Abstract: For container-carried explosives or contraband in which the container is made of conductive material and can therefore constitute a Faraday cage, stimulated emissions due to nuclear quadrupole resonance are detected utilizing a terminated balanced transmission line and a directional coupler for the detection of explosives, contraband, narcotics and the like that exist in metal containers.

Abstract: A programmable transversal structure that may serve as a filter, or more generally, a transversal network. A pair of time delay elements are implemented using one or more grating control propagation path structures, multilayer waveguides with configurable gaps, or variable impedance meander lines. Electro active actuators responsive to bandwidth, center frequency, and stop band attenuation control inputs control the delay of such elements. Impedance elements are distributed between the time delay elements to provide the desired transversal response.

Abstract: Nuclear quadrupole resonance measurement using two or more wire loop(s) within a space to define a portal, and driving the wire loop(s) with a baseband digital transmitter generating a chirped or stepped signal, to create a corresponding varying electromagnetic field within the portal. Coherent emissions reflected thereby are detected through a directional coupler feeding the transceiver. The detected coherent emissions are processed with a matched filter to determine presence of a target object within the portal.

Abstract: A low profile antenna using a cavity-backed central radiating surface surrounded by one or more ground plane surfaces. Passively reconfigurable structure provide frequency dependent coupling between the surfaces. The frequency dependent couplings may be implemented using meander line structures, Variable Impedance Transmission Lines (VITLs), or tunable VITLs that used interspersed electroactive sections.

Abstract: Reconfigurable Chirp Fourier Transform (CFT) based continuous convolution apparatus(es) and method(s) that are effectively used, for example, in interference cancellation applications.

Abstract: A nuclear quadrupole resonance system which senses the stimulated emission from target molecules includes in a calibration step and a stimulated emission response detection step, with the system employing clutter cancellation involving linear regression and the use of cross correlation with a series of known molecular signatures, both increasing the signal-to-noise ratio of the system.

Abstract: Disclosed herein are systems and computer readable storages for identifying experts with particular talents among participants in an online social network. Identification of experts with particular talents identified by talent-labels can take into account multiple factors. One factor that can be applied is self-nomination. Individuals who offer to help others can be expected to offer assistance in areas where they have strong talents. Another factor that can be applied is endorsements by others. A co-worker making an endorsement can be encouraged or required to supply narrative that describes experience with the nominee's actual work. Another factor that can be applied is data mining by semantic analysis or other techniques, taking advantage of access to fielded databases that describe a nominee's work activities.

Abstract: A neuromorphic parallel image processing approach that has five (5) functional layers. The first performs a frequency domain transform on the image data generating multiple scales and feature based representations which are independent of orientation. The second layer is populated with feature based representations. The third layer, an object class recognizer layer, are fused using a neuromorphic parallel processor. Fusion of multimodal data can achieve high confidence, biometric recognition.
