A Lobster Eye X-ray Imaging System based on a unique Lobster Eye (LE) structure, X-ray generator, scintillator-based detector and cooled CCD (or Intensified CCD) for real-time, safe, staring Compton backscatter X-ray detection of objects hidden under ground, in containers, behind walls, bulkheads etc. In contrast to existing scanning pencil beam systems, Lobster Eye X-Ray Imaging System's true focusing X-ray optics simultaneously acquire ballistic Compton backscattering photons (CBPs) from an entire scene irradiated by a wide-open cone beam from one or more X-ray generators. The Lobster Eye X-ray Imaging System collects (focuses) thousands of times more backscattered hard X-rays in the range from 40 to 120 keV (or wavelength λ=0. 31 to 0. 1 Å) than current backscatter imaging sensors (BISs), giving high sensitivity and signal-to-noise ratio (SNR) and penetration through ground, metal walls etc. The collection efficiency of Lobster Eye X-ray Imaging System is optimized to reduce emitted X-ray power and miniaturize the device.

An improved stacked rotary connector assembly wherein each connector comprises a pair of rings and the rings of each rotary connector thereof are individually split and mechanically separable. Because the input and output rings are each split and separable, any one rotary connector may be removed from the stack without requiring removal of any other rotary connector and without disturbing the input/output buses of the assembly.

Two embodiments of a connector that can be mated without regard for its orientation are disclosed. One embodiment is mated and demated autonomously as part of a system for recovering, docking with, recharging and re-launching unmanned aerial vehicles. Another embodiment is employed on the decks of vessels to facilitate mating and demating of various equipment providing different functions to reconfigure the vessel. Because both embodiments are configured for connection irrespective of angular orientation over 360, they are especially suited for harsh environments including autonomous operation, rough seas, darkness and the like.

An entirely wearable electrical connector for power/data connectivity. The principal element of a modular network is the wearable electrical connector, which is integrated into a personal area network with USB compatibility. Several wearable connector embodiments are disclosed. The first, an O-ring based version, was subsequently replaced by a more mature second version, which is based on anisotropic pressure sensitive conductive elastomer. Both are snap-style, low-profile, 360-moving, round, blind operable plug-and-play, reconfigurable wearable connectors with power/data daisy-lattice-style connectivity. A third embodiment comprises a non-conductive elastomeric environmental seal. A fourth embodiment utilizes a self-acting, automatic shutter-type environmental seal. A fifth embodiment comprises a smaller version that resembles a conventional snap fastener commonly used on clothing. The inventive technology will benefit the military and public safety personnel such as police, fire, EMT and other services that require special protective clothing integrated with multiple electronic devices.

A carton-centric security system that uniquely combines a low-cost version of the rugged connector technology and a novel smart skin is provided. The carton-centric security system includes RF electronics for communication. The system can fully meet the homeland security need to autonomously seal, secure, and monitor the integrity of shipping cartons/parcels below the ISO intermodal shipping container level. The system can seal the contents of a shipping carton within a “smart skin/wrapper,” which physically surrounds the contents, monitors the physical integrity of the shipping carton and detects any intrusion into the carton. In case of an intrusion, the system provides notification of the intrusion of the carton or tampering with the carton security system, including alteration of the carton contents, theft or unauthorized removal of the entire carton.
