• US Patent 8,412,391, April 2, 2013 - ., Proximity Spacecraft Maneuvering.

Provided is a method and system for maneuvering a first spacecraft relative to a nearby second spacecraft that occupies a finite volume of space including obstacles in the vicinity of the second from a measured present relative position to a desired ending relative position. A trajectory is computed for the first spacecraft from the present relative position to the ending relative position using the A* algorithm. One or more thrusters of the first spacecraft are then fired. The first spacecraft's relative position and velocity are then measured and compared to the computed trajectory.

• U.S. Patent 8,311,679, November 13, 2012, Matrix converters for wind energy conversion systems .

The invention is an efficient matrix converter for wind energy conversion systems (WECS) using permanent magnet DC generators, incorporating control algorithms integrated with rotor aerodynamics, generator dynamics and the wind environment. Using a complete model of the system enables the design of an integrated control scheme for the WECS that improves the overall system efficiency. Estimates of wind velocity and rotor speed measurements are fed forward to the matrix converter subsystem for efficient switching..

• U.S. Patent 8,193,657, June 5, 2012, Vertical Axis Wind Turbine Using Individual Blade Pitch and Camber Control Integrated with Matrix Converter.

A vertical axis wind turbine that can be actively controlled is provided. This invention includes mechanisms and methods for enabling high-efficiency wind energy extraction by a vertical axis wind turbine using active pitch and camber control of individual blades. Blade control is further integrated with generator control and power electronics. Integrated control algorithms are systematically constructed, and transmitted to the wind turbine through a wireless communications interface. The interface also allows the user to continuously monitor the state of the wind turbine system. This invention includes sensors and procedures for periodic self-calibration of wind turbine parameters for preserving the long-term efficiency of wind energy extraction. Furthermore, a capability to intelligently interact with other wind turbine systems in a wind-farm setting is incorporated.

• U.S. Patent 8,081,302, December 20, 2011, Multimode Optical Sensor.

A Multimode Optical Sensor (MMOS) is a laser radar (ladar) that employs both coherent, or heterodyne, and noncoherent detection at long range, i.e. ranges for which the target is no more than a pixel in dimension. Coherent detection provides much higher velocity resolution while the noncoherent detection can provide better detectability.
