  • Governor for elimination of repetitive requests
    Patent number: 9122519
    Abstract: A browser invokes a program from a server. The server responds with a web page and ancillary logic. The browser displays the web page and loads the logic into memory. The ancillary logic includes a command set, a status indicator for each command type, and a set of command type governors. When a command is initiated at the browser, the appropriate governor observes the status, and deletes the command if the status is “not complete” or passes the command for transmission to the server if the status is “completed.” This prevents the transmission of repeated or redundant commands to the server.

  • Single Platform Doppler Geolocation
    Publication number: 20150241545
    Abstract: To make small UAVs capable of geolocation of emitters, a low cost, low power, small weight and power radio receiver receives and tracks Doppler frequency at a minimum. In order to minimize the size, weight and power (SWAP), a single receiving element array is utilized. The analysis of geolocation performance with single and multiple UAV receiving platforms is considered. With a single UAV platform measuring Doppler frequency with unknown center frequency, a localization accuracy on the order of ten to 100 meters is possible within a couple of minutes, or about one to five percent of the target range.

  • Thruster orbit control method and configuration
    Patent number: 9114890
    Abstract: Embodiments of the present invention provide an ion-thruster stationkeeping method and mounting configuration that reduces the propellant penalty when a single thruster fails, e.g., in the case where only three of a spacecraft's four ion thrusters are available. By improving firing efficiency for the single-thruster failure case, on-board propellant is reduced, thereby allowing increased payload mass. Also, the configuration supports both N/S and E/W stationkeeping using four ion thrusters (or three thrusters for the failure case) and therefore does not require a separate propulsion system or thrusters for E/W stationkeeping.

  • Social identity models for automated entity interactions
    Patent number: 9117316
    Abstract: One or more social interactive goals for an automated entity such as an avatar may be determined during a social interaction between the automated entity and a selected entity such as a human. Identity attributes of identity images from an identity model of the automated entity may be used to determine a set of behavioral actions the automated entity is to take for the determined goals. Paralanguage elements expressed for the automated entity via a user interface may be altered based on the determined set of behavioral actions. The automated entity may refer to a computer implemented automaton that simulates a human in the user interface of an interactive computing environment. By way of example, an avatar cybernetic goal seeking behavior may be implemented in accordance with an identity theory model.

  • DE-CENTRALIZED CONTROL ARCHITECTURE FOR IMPROVED SENSITIVITY OF ACCELEROMETER-BASED GRAVITY GRADIOMETERS
    Publication number: 20150234085
    Abstract: A method for rebalancing a group of accelerometers in a gravity gradiometer instrument (GGI) includes the steps of defining and implementing a number of group-wise actuation constrainment modes based on a design of the gravity gradiometer instrument and its accelerometers. Implementing one constrainment mode comprises differentially scaling and distributing a single electrical current to multiple accelerometers' rebalance circuitry to cancel a specific acceleration effect experienced by the group of accelerometers or gradiometer as a whole. Superposition of a number of such modes enables rebalancing the full acceleration environment experienced by the group of accelerometers, given negligible local differential acceleration effects specific to, say, an individual accelerometer of the assembly.

  • Method and apparatus for detection of multiple pulses in a radio frequency spectrum
    Patent number: 9110148
    Abstract: A method and apparatus for detection of multiple pulses present in a radio frequency (RF) environment comprises receiving the RF signal, sampling the RF signal and converting the samples from analog to digital. In-phase and quadrature components of the samples are converted to magnitude and phase. Magnitude and phase information is processed in parallel paths, each path tuned to detect pulses of a specific pulse width of interest. Filtered magnitude and phase data is processed to detect pulses. Multiple detected pulses from different processing paths are analyzed to characterize each detected pulse as to its originating source. Pulse width and time of incidence are compared to determine if multiple detected pulses represent a single pulse or unique and separate pulses. Pulse descriptor words are generated for each uniquely identified pulse.
