Abstract: Systems and techniques are provided for adjusting the planned path of an autonomous vehicle to converge with the actual path. An example method can include determining a first pose error associated with a first pose component from one or more pose components, wherein the first pose error is based on a first difference between an actual pose of an autonomous vehicle and a planned pose of the autonomous vehicle; determining that the first pose error associated with the first pose component exceeds a pose error threshold corresponding to the first pose component; and generating a new planned pose of the autonomous vehicle that yields a reduced first pose error associated with the first pose component, wherein the reduced first pose error is based on a second difference between the actual pose of the autonomous vehicle and the new planned pose of the autonomous vehicle.

Abstract: Architectures and techniques for initializing a simulation architecture are described. A platform model and an environment model are run on recorded data during a first period of time. The platform model and the environment model provide information to control modules. The platform model is run on a blended combination of recorded data and data from the set of control modules and the environment model is run on processed output data from the platform model during a second period of time. The platform model is run on data from the set of control modules and the environment model is run on output from the platform model from a previous period of time during a third period of time. Output signals from the platform model can be adjusted based on a subset of the recorded data during the first, second and/or third period of time.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: This invention is a pay charging station for electric and plugin hybrid vehicles. A vehicle parks at a space with the charging station and uses a credit card, debit card, cash, smart card or network connection to a database like EZ-Pass to pay for the space and the electricity. The station automatically charges the vehicle as long as it is connected to the station. The station automatically stops charging when the vehicle is fully charged. The customer only pays for the space and the electricity consumed. If the charging circuit is broken the customer must reinsert the smart card or credit card to restart charging. Sufficient funds are removed from the payment method on initiation of charging. Any money not used for charging is returned to the funding account upon the user reinserting the smart card, credit card or debit card, or cash change is returned if cash was the method of payment.
