Abstract: A theft detection system includes a sensor having a magnetic ball axially moveably supported within an axial opening in the spool having an electrical coil wound around the spool such that movement of the ball creates electrical signals in the coil. A housing is configured to support and vibrationally couple the sensor to a vehicle exhaust system. A circuit is coupled to the electrical coil to receive the electrical signals and generate an alarm signal in response to movement of the ball being indicative of vibration of the exhaust system resulting from exhaust system tampering.

Abstract: A communication network includes nodes configured into a wireless ring network operating at one or more millimeter-wave frequencies. At least one of the nodes is configured to send and receive millimeter-wave wireless signals through an obstruction. In accordance with an exemplary embodiment of the network, one or more of the nodes may include small, phased-array antennas and transceivers, configured with radio electronics to mitigate the path loss through certain obstructions, such as walls, floors, ceilings, and other barriers within buildings, as well as attenuation from free-space path-loss, including moisture in air (humidity). The network may include multiple pairs of nodes to form one or more wireless communication paths through various obstructions. This may allow a high-speed, wireless, multi-ring network to be established, for example, within a structure, such as a building, without requiring additional cabling or wiring.

Abstract: A thin walled balloon formed in polymer tubing has a patterned metal layer on its outer surface, created by physical vapor deposition (PVD). The pattern is defined by a stencil mask assembled around the balloon, with the balloon inflated therein. The PVD occurs without deforming or degrading the polymer material of the balloon, by actively pulling heat away from the balloon a) by forming the stencil mask out of metal; b) by providing a metal heat conduction path away from the balloon to a heat sink, such as outside the vacuum chamber, and/or c) by flow of a cooling fluid within the balloon during the PVD process. Proper PVD process parameters are selected to minimize heat generation, such as having argon pressure in the range of 0.8 to 1.2 milli-torr and generating the plasma at a power of less than about 200 watts/square inch of effective target surface area.

Abstract: This disclosure is directed to hydrodynamic electric generators, including their structural design, methods of deployment, anchoring systems, drive systems and control systems. The system can be scaled from ones that can be hand carried to large, stationary devices that can generate up to and greater than 20 kw in a current of 3 knots. In a stationary system, the device can be anchored to an underwater floor by an anchoring device supported by four adjustable legs. These legs can eliminate the need for extensive mooring lines, providing the device with a small footprint that is non-hazardous to marine animals or vegetation. Individual components, such as rotors, generators and other mechanical components can be modularly installed for easy removal and servicing without having to disturb the entire system.

Abstract: An ophthalmic surgical cutting apparatus for cutting biological material including a handle, an outer tube attached to the handle and having a closed tip, a port formed in a side wall of the outer tube with a cusp formed by two or more intersecting surfaces, and an inner tube slidable within the outer tube and having a longitudinal axis and an open tip. The inner tube is in fluid communication with the handle, and the cusp of the port and the open tip interface during a cutting motion to fracture and cut biological materials and direct cut materials radially inward into the port.

Abstract: The present disclosure provides improved methods for controlled cyclization of peptoid dimers to form N,N?-2,5-diketopiperazines (N,N?-2,5-DKPs) with significant selectivity. In at least some examples, selectivity is based on a serendipitous conglomeration of slow exchange of amide rotamers, steric repulsion from the degree of ?-substitution, and the geometric bulk of an amine nucleophile. By varying reaction conditions, the selectivity of the reaction and formation of a particular N,N?-2,5-DKP can be switched. The cyclization works in the presence of a variety of protection groups and diverse functionalities. The teachings herein provide techniques for synthesizing N,N?-2,5-DKPs that can be readily docked with drug candidates for shuttling across the blood brain barrier. This method provides a facile way to produce substituted DKPs containing groups ready for post-modification to include docking drug candidates.
