20150261223 | ADAPTIVE MAPPING WITH SPATIAL SUMMARIES OF SENSOR DATA - A system and method for mapping parameter data acquired by a robot mapping system is disclosed. Parameter data characterizing the environment is collected while the robot localizes itself within the environment using landmarks. Parameter data is recorded in a plurality of local grids, i.e., sub-maps associated with the robot position and orientation when the data was collected. The robot is configured to generate new grids or reuse existing grids depending on the robot's current pose, the pose associated with other grids, and the uncertainty of these relative pose estimates. The pose estimates associated with the grids are updated over time as the robot refines its estimates of the locations of landmarks from which determines its pose in the environment. Occupancy maps or other global parameter maps may be generated by rendering local grids into a comprehensive map indicating the parameter data in a global reference frame extending the dimensions of the environment. | 09-17-2015 |

20090106800 | Controlling supplementary data channels using display state information - Controlling supplementary data channels using display state information involves processing, at a user device, a first broadcast signal having a content channel and a second signal having a supplementary data channel. The supplementary data channel is related to the content channel. The broadcast channel and supplementary channel are rendered to a user via the user device. The supplementary channel is at least partially rendered on a display of the user device. An event is determined that causes the display to be no longer viewable by the user. In response to determining the event, processing and rendering the supplementary data channel is ceased. The action of ceasing to process the supplementary data channel results in lowering power consumption of the user device. | 04-23-2009 |

20100320759 | Method and apparatus for ocean energy conversion, storage and transportation to shore-based distribution centers - A fleet of vessels attached together longitudinally (rows), and transversely (columns) and operating in unison convert wave energy to electrical energy which is stored in either a chemical or electrical form. The vessels when detached from the fleet provide transportation to coastal or by navigable waterway ports of call for distribution to market centers. Both wind wave and swell wave energy conversion is performed by use of the differential motion between the vessels. Means are provided for the energy conversion systems to adapt to changes in wave direction, wave length, amplitude, and phase. Such vessels are self powered for off shore or inland waterway navigation, either singularly or in multiples, with which to deliver energy to other sea going vessels or to land based ports of call. Two or more of such vessels are capable of using the energy of waves during the delivery process. The fleet can maintain a designated geographical location by dynamic positioning. Alternatively, the fleet may maintain its designated position by moorage of a designated centrally located vessel in the fleet to a permanent anchoring system when operating at appropriate depths. | 12-23-2010 |
