Abstract:
A method and system referred to as PALM (Patterning by Adhesive of Large Relief Three- Dimensional Micro structures) with large reliefs exceeding 1 μm and being as large as 100 μm. The Micro structures can be either deterministic (such as micro prisms), or random (such as diffusers), the first obtained by copying an original super master, and latter obtained by copying a laser speckle pattern. The master process entails copying a super master into the form of the micro structure constituting a pattern on the patterning cylinder (called a drum), to be then continuously multiplied in the PALM system, in a continuous roll-to-roll web process. The latter method, together with the related system, is the subject of this invention. The rolls continuously repeat the master pattern, copying by adhesive with large viscosity on acrylic (hybrid) as well as by a monolithic process. The monolithic process can be accomplished using temperature and pressure, or by UV-cured polymerization. Therefore, the invention comprises three alternative processes: one, hybrid (adhesive on acrylic), and two monolithic ones. In the PALM (hybrid) process, an epoxy is wet-coated on film substrates such as polycarbonate (PC), polyester (PET), (PE), or other flexible material. The adhesive, in liquid form, is applied to the substrate by a self-metered coating sub-process. In the present invention, the adhesive is used for forming the micro structure pattern. The micro structure pattern is replicated from a master roll or image drum onto a coating roll.

Abstract:
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.
Abstract:
An optical impact system controls munitions termination through sensing proximity to a target and preventing effects of countermeasures on false munitions termination. Embodiments can be implemented on in a variety of munitions such as small and mid caliber that can be applicable in non-lethal weapons and in weapons of high lethality with airburst capability for example and in guided air-to-ground and cruise missiles. Embodiments can improve accuracy, reliability and lethality of munitions depending on its designation without modification in a weapon itself and make the weapon resistant to optical countermeasures.
Abstract:
The present invention relates to a connector configured as a fastening element. Some embodiments are in the form of a wearable "smart" electrical connector and associated connector system in the form of a modular network, which for the first time integrates electronics into protective clothing in a body-conformable and comfortable fashion. It has these unique features: wearability compatible with existing and future military/civilian vests/uniforms; a button-like snap-fastener that can be snapped and unsnapped "blindly" with one hand; and resilience to harsh temperature/humidity, chemicals, water and laundering. Another embodiment is employed in a carton-centric system to indicate tampering with the carton during transit.
Abstract:
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 A) 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. This device is especially advantageous for and satisfies requirements of X-ray-based inspection systems, namely, penetration of the X-rays through ground, metal and other material concealments; safely; and man-portability. The advanced technology disclosed herein is also applicable to medical diagnostics and military applications such as mine detection, securily screening and a like.
