A system for autonomous monitoring of AC and DC background magnetic fields associated with power lines, electronic devices, electronic vehicles and the Earth. The system enables the measurement of the natural variability of magnetic fields over specified periods of time within a specified proximity. Components include a series of three axis analog magnetic sensors, a fluxgate compass and a programmable micro-controller. The micro-controller receives data from the sensor and compass and is programmed to detect anomalous magnetic signals having particular characteristics of interest. Protected under U.S. Pat.

Robust, fault tolerant design offers substantial potential to easily retrofit and greatly improve performance and capabilities of existing patch antennas without altering the device footprint. The bandwidth of a prototyped GPS antenna was increased from a typical 2-5% to 20-25%. A highly anisotropic superstrate layer is placed over an existing patch antenna as a retrofit or incorporated into new systems to enable broader bandwidth capabilities for a given antenna while not compromising other performance characteristics. Substantial bandwidth improvement enables diverse, multiple capabilities from a single antenna (e.g. satellite telephone and GPS) and higher data transfer rates. Protected under US Pat.

An image analysis system comprised of software and hardware has been developed and prototyped for the evaluation of periscope head windows or any curved surface such as helicopter, or other aircraft, or surface ship window, including laser window analysis and evaluation. The invention has potential as a hand held tool for port-side platform head window quality analysis, greatly reducing labor, material and certification costs. Protected under US Pat. No. 9,219,890.
Developed as part of the Towed Array Handling System Measurement System (HSMS) for a towed array, the point load sensor measures how much squeeze type forces an array sees in the handler, irrespective of the arrays circumferential orientation as it goes through the handler. A critical part of the HSMS, the invention allows non-acoustic measurement and characterization of forces on the array to test the impact of engineering changes to the handler as well as new handling system concepts. The HSMS is reeled into and out of the handler with the submarine in dry dock or pierside and utilizes the existing ship signal path eliminating the need for ship alterations or diver support.
