20120201096 | Methods and Apparatus to Process Time Series Data for Propagating Signals in A Subterranean Formation - Methods and apparatus to process time series data for propagating signals in a subterranean formation are disclosed. An example method described herein for processing measured data comprises receiving a time series of measured data obtained by sensing a propagating signal, the propagating signal having passed through a subterranean formation, transforming the time series of measured data to generate a time-frequency representation of the time series, and processing the time-frequency representation to at least one of reduce noise in the time frequency representation, or enhance a component of the propagating signal present in the time-frequency representation. | 2012-08-09 |

20120201098 | COMPENSATION FOR DEPTH FINDERS - System and methods for compensating a depth signal for a depth finder of a boat. In one embodiment, a compensation system is implemented between the depth finder and a transducer mounted on the boat. The compensation system receives a depth signal (i.e., a plurality of electrical impulses) from the transducer that directs sound waves toward the bottom of a body of water. The compensation system also monitors a change in elevation of the transducer, such as due to waves rocking the boat. The compensation system then compensates the depth signal based on the change in elevation, and provides the compensated depth signal to the depth finder. | 2012-08-09 |
20120201099 | METHOD FOR SIMULTANEOUSLY LOCATING AND MAPPING VIA RESILIENT NON-LINEAR FILTERING - A method including carrying out, by means of an underwater vehicle moving above a given zone of the sea bed, observations on the basis of which the positions of elements of relief and of objects present on the bed are estimated. These observations are associated with fictitious objects, tied together by fictitious elastic links so as to constitute a fictitious elastic network. The network is in equilibrium as long as no action is exerted on one or the other of the fictitious objects constituting the network. The objects then occupy fixed positions, positions assigned to the corresponding observations. On the other hand, when two observations assumed to correspond to one and the same object are fused into a single observation, the two corresponding fictitious objects are brought closer together. This bringing closer together induces the appearance of stresses in the fictitious elastic network. These stresses, transmitted by the fictitious elastic links, are resolved by the modification of the positions of the fictitious objects of the network, the modified positions being assigned to the corresponding observations. In this way, when the estimated position of an object having formed the subject of two fused observations is corrected, the measurement of the estimated position of each of the objects that has given rise to an observation represented in the fictitious elastic network benefits advantageously from this correction. | 2012-08-09 |

These thermal variations create temperature variations within the transducer head. Two resistance temperature sensors on the transducer head at varying distances from the close point and/or light source measure these temperature variations. A temperature difference between the two resistance temperature sensors indicates proximity of the close point to the media and/or light output. | 2012-08-09 |

20120201195 | Macro-Network Location Determination, Local-Oscillator Stabilization, and Frame-Start Synchronization Based on Nearby FM Radio Signals - Exemplary methods and systems may generally be implemented to allow a macro-network base station without access to a GPS reference signal to provide some or all of the functionality for which existing macro-network base stations typically rely on GPS. In a first aspect, an exemplary macro-network base station may determine its location using a location-determination technique that is based upon the angles of arrival of FM radio signals from nearby FM stations. In a second aspect, an exemplary macro-network base station may stabilize its local oscillator by phase-locking its local oscillator to an FM radio signal, and periodically adjusting its local oscillator to account for phase drift of the FM radio signal. And in a third aspect, an exemplary macro-network base station may synchronize its frame-start timing with a nearby base station using a frame-start timing signal that the base station has synchronized to frame transmissions from the nearby base station during a setup routine. | 2012-08-09 |
