  • Patent number: 8309371
    Abstract: A system and method include forming an optical cavity by positioning a photonic crystal a predetermined distance from a substrate, and creating, within the cavity, a standing wave having a substantially flat wavefront. The standing wave may be created by applying an input wave to a first surface of the photonic crystal. The predetermined distance may be such that a peak intensity of the standing wave is proximate to or a calculated distance from the substrate surface. The peak intensity may vary in relation to the substrate surface. The method may include tuning the peak intensity location within the cavity by shifting the wavelength of the input wave or altering the characteristics of the photonic crystal by an external field. A second photonic crystal may be used on the other side of the substrate to replace the reflecting properties of the substrate, allowing for further smoothing of the wavefront.

  • Patent number: 8280831
    Abstract: A system and method for inductive and analogical reasoning provide capabilities for generalization, creative reasoning, possibilistic analysis, massive parallelism, and distributed processing. The system and method involve using matched cases/generalizations/analog inferences from a case base or generalization/analog base to provide output inferences based upon a user-supplied context. A user then provides feedback to indicate that the output inference is either correct or incorrect. If the user indicates that the output is incorrect, new rules may be computer-generated during runtime by performing, for example, an analogical contextual transformation. If the user indicates that the output is correct, the matched case/generalization/analog may be moved to the head of its respective base.

  • Patent number: 8204715
    Abstract: A method allows for determining the quality of a vessel's moment estimate and track information derived from a suite of sensors measuring the local magnitude of the magnetic field. A Bayesian treatment, employing a Markov Chain Monte Carlo approach with Gibbs sampling is applied with reduced magnetic noise spatio-temporal correlation models and implied whitening procedures. Vessel moment parameters are handled with a Gaussian prior leading to conditional densities that are Gaussian and posterior marginal densities that are mixture-Gaussian. Other conditional quantile functions for track parameters are computed with a grid procedure. From these, the Markov chain is determined and the resulting joint density of all variates is constructed. The method allows for determining posterior marginal densities and dependencies associated with magnetic moment and track parameters. The method may be stored in a storage device in a sensor and may be executed by a processor within the sensor.

  • Patent number: 8175796
    Abstract: A method involves transmitting a first signal to a device, the first signal comprising vehicle identification data and vehicle operational data, receiving a second signal from the device, the second signal comprising road and lane information and vehicle information vectors of other vehicles transiting the road in range of the device, and determining a collision risk based upon the received second signal. The method involves the range-limited communication of vehicle information vectors among a network of devices. The method may include transmitting an operational signal to a vehicle controller, wherein the operation of a vehicle, such as speed, braking, and steering, is altered by the vehicle controller based upon the received operational signal. The method may involve, if the determined collision risk exceeds a predetermined threshold, the transmission of a warning signal by a vehicle computer to a vehicle operator via a warning device controlled by a vehicle controller.

  • Patent number: 8136470
    Abstract: Buoyancy is controlled in a tethered object by pumping fluids, either of a first or second specific gravity, from an external source into either a first or second containment chamber to change the respective volumetric capacities of the first and second containment chambers. The containment chambers are configured such that the second chamber is at least partially enclosed within the first chamber. The second chamber is configured to expand and retract within the first chamber, which has a fixed housing. Expansion or contraction of the second chamber results in a corresponding inverse change in a volumetric capacity of the first chamber. The fluid chambers may be separate or contained within the same housing, and may be located on a towing vessel. Sensor data from the tethered object's environment may be used to control the transfer of fluid to the first and second chambers.
