20090146009 | Actuating Device - An actuator is configured for transmitting a force or torque to a load. In one example configuration, the actuator includes an input device configured to apply an output force. A backstopping clutch is configured to transmit torque only in the input direction and to prevent back-driving of the input device. An overrunning clutch is configured to include a driven member moved in response to the transmitted torque in the input direction. The load may be moved in response to the driven member, or the load may be moved by a force applied directly to the load. | 06-11-2009 |
20140137537 | Rotary Switch Assembly for Ion Propulsion System - A gridded ion propulsion system comprising two power controllers, four ion thrusters, and two switch assemblies. One switch assembly is connected to the two power controllers and to two of the four ion thrusters. The other switch assembly is connected to the two power controllers and to the other two ion thrusters. Each switch assembly has first and second switching states which can be selected to enable either power controller to supply power to any one of the four ion thrusters. Each switch assembly comprises a respective movable body and a respective multiplicity of switches which change state in unison when the movable body changes position. For example, the movable body may be a rotatable hollow shaft driven by a stepper motor. | 05-22-2014 |

20110178943 | Systems and Methods For Anonymity Protection - In any situation where an individual's personal attributes are at risk to be revealed or otherwise inferred by a third, there is a chance that such attributes may be linked back to the individual. Examples, of such situations include publishing user profile micro-data or information about social ties, sharing profile information on social networking sites or revealing personal information in computer-mediated communication. Measuring user anonymity is the first step to ensure that a users identity cannot be inferred. The systems and methods of the present disclosure, embrace an information-entropy-based estimation of the user anonymity level which may be used to predict identity inference risk. One important aspect of the present disclosure is complexity reduction with respect to the anonymity calculations. | 07-21-2011 |

20090125397 | METHOD AND SYSTEM FOR INTEGRATING RANKINGS OF JOURNALED INTERNET CONTENT AND CONSUMER MEDIA PREFERENCES FOR USE IN MARKETING PROFILES - A method and system for integrating data-source consumer-preference data and internet-medium consumer-preference data for use in targeted advertising and ranking content. Consumer-preference data is determined based on user-interactions with a data source, such as a set-top-box. The data source is classified based on a monitoring taxonomy that specifies content categories and relationships between the categories. The consumer-preference data and the data source classification are aggregated with other preference and classification data, which is used to rank the data source classification data. Journaled internet data sources are analyzed using the monitoring taxonomy to determine internet-medium consumer-preference data. The journaled internet data sources are ranked based interest level, direction level, or authority level. A content category ranking is computed using the ranking of data source classifications and the ranking of the journaled internet data sources, which can be provided as an advertising data input or a standalone content ranking reporting tool. | 05-14-2009 |
