  • Patent number: 8781640
    Abstract: Systems and methods are described herein for controlling the states of a microgrid module. The microgrid module includes transformers and/or power converters necessary for modifying the input AC or DC power sources to meet the required characteristics of the output power. The microgrid module further comprises a control software module installed on a microgrid computer. The control software module receives data associated with the operating state of the microgrid module. The control software module can access rules associated with each microgrid module operating state to determine whether the microgrid module must transition to a different operating state. If a transition is appropriate, the control software module can apply commands to transition the microgrid module to a different operating state. The control software module can continue to monitor the microgrid module to determine when another state transition is appropriate.

  • Publication number: 20140139842
    Abstract: Systems and methods are described herein for a self-referencing interferometer. The interferometer can comprise an improved spatial phase shifter that reduces the number of components, size and complexity of the spatial phase shifter and maintains a common path for a combined reference beam and signal beam. The self-referencing interferometer further comprises a single mode fiber shunt for filtering the reference beam and further reducing the size of the interferometer. The angle of the reference beam can be tilted before being recombined with the single beam which further simplifies the spatial phase shifting component of the interferometer.

  • Publication number: 20140029898
    Abstract: A cable termination device may include one or more components that are generic to multiple types and/or sizes of cable. The device may further comprise one or more components that are specific to a particular cable type and/or size. The cable-generic components can be combined with cable-specific components applicable to the particular cable type and/or size so as to assemble a termination device attached to an end of a cable of that particular type and/or size. The cable-generic components could alternatively be combined with cable-specific components applicable to a different cable type and/or size so as to assemble a termination device attached to an end of a cable of that different type and/or size.

  • Patent number: 8566930
    Abstract: A system and associated method for monitoring the execution of software on one or more computers by receiving traffic from within the monitored computer(s). The monitoring may take place passively, such that the operation of the monitored computer or computers is completely unaffected by the monitoring. More intensive monitoring, such as maintenance of a shadow copy of the RAM of the monitored computer, may be initiated upon recognition of a pattern in the data received from the monitored computer. The execution of software on the monitored computer may be halted by the monitoring module. The monitoring module may also read from or write to the memories of the monitored computer.

  • Patent number: 8554607
    Abstract: A method and system for securely voting over a network, such as a global computer network, involves a system which delivers an electronic ballot from a server with the server's private key and a vote serial number on the ballot to an individual terminal connected to the network. The ballot may be filled in and a subset of the filled-in ballot is created with a digital signature created from the individual's secret key on the subset of the ballot corresponding to the ballot choices. The subset of the filled-in ballot together with the individual's electronic signature, and a vote serial number is then delivered to the server. A data element is then created to record a subset of the ballot in a data store at the server, in which the ballot vote information is retained as a vote.

  • Publication number: 20130248722
    Abstract: Systems and methods are described herein for performing three-dimensional imaging using backscattered photons generated from a positron-electron annihilation. The systems and methods are implemented using the pair of photons created from a positron-electron annihilation. The trajectory and emission time of one of the photons is detected near the annihilation event. Using this collected data, the trajectory of the second photon can be determined. The second photon is used as a probe photon and is directed towards a target for imaging. The interaction of the second probe photon with the target produces back scattered photons that can be detected and used to create a three-dimensional image of the target. The systems and methods described herein are particularly advantageous because they permit imaging with a system from a single side of the target, as opposed to requiring imaging equipment on both sides of the target.

  • Publication number: 20130188524
    Abstract: The invention provides a set of mechanisms by which a wireless mobile mesh node equipped with a directional antenna may self form and self adapt its steady-state communications schedule. A link establishment handshake is carried out over an ongoing subtemplate-based discovery scan. During time not reserved for steady-state communications with previously discovered neighbors, nodes continue to search for an establish links with new neighbors. Initial and subsequent bandwidth allocation protocols may be utilized to allow peer nodes to coordinate communication opportunities between the peer nodes without impacting or having knowledge about reservations for communications with other peers. The link establishment and initial bandwidth allocation protocols may be piggy-backed for readily establishing an initial steady-state schedule with a peer upon link establishment without impact on previous steady state reservations by other nodes or on ongoing link establishment attempts elsewhere.

  • Publication number: 20130103195
    Abstract: A system and method can provide a command and control paradigm for integrating robotic assets into human teams. By integrating sensor to detect human interaction, movement, physiology, and location, a net-centric system can permit command of a robotic platform without an OCU. By eliminating the OCU and maintaining the advantages of a robotic platform, a robot can be used in the place of a human without fatigue, being immune to physiological effects, capable of non-humanoid tactics, a longer potential of hours per day on-station, capable of rapid and structured information transfer, has a personality-free response, can operate in contaminated areas, and is line-replaceable with identical responses. A system for controlling a robotic platform can comprise at least one perceiver for collecting information from a human or the environment; a reasoner for processing the information from the at least one perceiver and providing a directive; and at least one behavior for executing the directive of the reasoner.

  • Patent number: 8422798
    Abstract: Embodiments of the invention view image intensity data as a spectrum of underlying wave forms. The spectrum of these waves can be approximated using spectral estimation techniques where the spectrum parameters constitute the compressed image. The image's underlying wave forms can be recovered using an inverse Fourier transform. The original image can also be symmetrically extended prior to the transform to preserve real valued transformed data and model parameters. The modeling method is typically based on a linear predictive methodology to obtain the spectrum parameters. Other transforms include a 2-D Fourier transform that transforms the image into a holographic representation similar to synthetic aperture radar (SAR) phase history. This 2-D waveform holographic format can be decorrelated into 1-D planar waves by applying a 1D Fourier transform. This process enables 1-D linear predictive modeling to obtain the spectral parameters. For compression applications the model parameters are preferably quantized.

Prior to modeling, one-dimensional Fourier transform can be performed on the holographic representation and the linear prediction is one-dimensional. Model parameters are preferably quantized. Embodiments include determining error between the model and the model's input data. There the compressed image representation the error, which also can be quantized. The subset of the holographic representation can be less than all the representation. The subset can be a plurality of complete rows; preferably substantially symmetric about 0 Hz.
