Abstract: An inspection system for inspecting a machine includes an inspection vehicle constructed for wireless operation while submersed in a dielectric liquid medium. The inspection vehicle is self-propelled. A controller is operative to direct the activities of the inspection vehicle. A plurality of status interrogation systems is disposed on the inspection vehicle. The status interrogation systems are operative to capture inspection data regarding a plurality of inspection procedures performed on the machine.

Abstract: A method for verifying user participation includes generating a motion signature associated with an event. The motion signature is generated on a mobile device with a user during the event. The mobile device includes one or more sensors configured to detect motion. The method includes comparing the generated motion signature with a predefined motion signature associated with the event. The predefined motion signature is stored in an event library that includes a plurality of predefined motion signatures, where each predefined motion signature is associated with an event. The method includes verifying that the user participated in the event by verifying that the generated motion signature matches the predefined motion signature of the event.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying entities using search results. One of the methods includes determining that a first search query includes a respective text reference to each of one or more predetermined attributes, wherein each attribute is associated with a first entity type; obtaining search results for the first search query from a search engine, the search results identifying a plurality of resources; identifying entities of the first entity type that are related to any of the plurality of resources identified by the search results; and selecting names of one or more of the identified entities of the first entity type to include in a response to the first search query.

One of the methods includes the actions of determining that a first search query includes a respective text reference to each of one or more predetermined attributes, wherein each attribute is associated with a first entity type; generating a second search query including the first search query and one or more terms that refer to the first entity type; and evaluating search results obtained for the second search query to select one or more names of entities of the first entity type to include in a response to the first search query.

Abstract: A method is disclosed for using information related to the service history of a power-train component. The method may include using a machine-management system with at least one information processor to acquire information related to loads experienced by the power-train component during a first period, the first period occurring before a disassembly procedure involving disassembly of the power-train component from a power train. The method may also include employing the machine-management system and the acquired information related to loads experienced by the power-train component during the first period to perform one or more tasks in connection with use of the power-train component after the disassembly procedure.

Abstract: A coherence shifting interferometry system determines the thickness or refractive index of an optically transmissive medium. The system utilizes an optical energy source for generating a source beam. The source beam is divided into two beams by reflecting one portion of the beam off of a reflective surface, e.g., a front surface, of an optically transmissive test sample having the unknown thickness or refractive index. A second portion of the beam is transmitted through the sample and reflected off a refractive interface in the sample, e.g., a back surface. The two reflected beams are combined into a composite beam. The composite beam is then directed to a Mach-Zehnder type interferometer, where a portion of the combined beam traverses a fixed optical path length, and another portion traverses a variable optical path length.
