Abstract: A computerized method of creating map data from a plurality of trips where each trip comprises position data derived from the positions of at least one navigation device over a period of time, the method comprising using a processing circuitry to perform the following steps: i. processing the position data; ii. calculating, from the processing of the position data, trip terminal positions at which the navigation device started to generate positions and/or stopped generating positions and which provide an end point of a trip; iii. performing statistical analysis on the terminal positions in order to determine origin locations at which trips commonly terminate and/or originate; iv. generating further map data, which comprises the origin locations.

Abstract: Example data storage systems and methods are described. In one implementation, a method identifies data to be written to a shared storage system that includes multiple storage nodes. The method communicates a write operation vote request to each of the multiple storage nodes. The write operation vote request is associated with a data write operation to write the identified data to the shared storage system. A positive response is received from at least a portion of the multiple storage nodes. The data write operation is initiated in response to receiving positive responses from a quorum of the storage nodes.

Abstract: A three-phase stacked triangular transformer core is provided. The transformer has three legs and six yoke parts therebetween, wherein the legs include stacked laminations. In a cross-sectional plane perpendicular to a central transformer core axis, the stacked laminations are oriented in substantially radial direction, and each leg has two leg halves, wherein each leg half has a plurality of outer corners facing a corresponding leg half of a neighboring leg. For each of the leg halves the plurality of outer corners lie on a respective straight line within a lateral tolerance, and for each leg half the straight line defined by this leg half and the straight line defined by the corresponding leg half of the neighboring leg are parallel.

Abstract: A method for manufacturing a stacked triangular core transformer includes assembling a triangular core by positioning of two halves of one leg on an assembly stand in the horizontal position; securing the positioned halves; positioning an outer clamping beam underneath two leg halves at the one end of the leg halves; assembling a yoke segment at the one end of two halves of the core leg; and forming a first clamp of the frame. The method continues by forming a second clamp of the frame at the other end of the two halves of the core leg by repeating the above positioning, assembling and forming steps; tightening the clamps together by securing means; rotating a single core frame into vertical position and releasing securing bar of the assembly stand; assembling two additional single core frames by repeating the above steps; positioning the frames in abutting position, and tightening them together.

Abstract: Example data storage systems and methods are described. In one implementation, one or more processors implement multiple virtual machines, each of which is executing an application. A virtual controller is coupled to the processors and manages storage of data received from the multiple virtual machines. Multiple I/O channels are configured to communicate data from the multiple virtual machines to a data storage node based on data storage instructions received from the virtual controller.

Abstract: A storage pool component is operable on a computing device including a storage medium having an otherwise free storage capacity for forming a portion of a storage capacity of a storage pool and being operably connected across a network to at least one other such component. The component comprises configuration data identifying at least one other computing device to which the computing device may connect across the network; and a directory for identifying file information for files of the storage pool stored on the storage medium, the file information being stored with a degree of redundancy across the computing devices of the storage pool. On instantiation, the component for communicates with at least one other component operating on one of the other computing devices to verify the contents of the directory. The component reconciles file information stored on the storage medium with file information from the remainder of the storage pool.

Abstract: A computer arrangement is disclosed, including a processor and a memory that stores a computer program, object data originating from a first source and including object location data, and laser samples originating from a second source, including a sub-set of laser samples relating to the object and including laser sample location data as to each laser sample. In at least one embodiment, the processor compares the object location data and the laser sample location data of the sub-set of laser samples, and matches the object location data to the laser sample location data of the sub-set of laser samples based on this comparison, and thereby corrects for relative positional errors between the first and second sources of location data. The object may be a building façade, for example.

Abstract: A method is disclosed for generating an orthorectified tile. In at least one embodiment, the method includes retrieving source images obtained by way of a terrestrial based camera; retrieving position data associated with the source images; retrieving orientation data associated with the source images; and converting source image by means of corresponding position data and orientation data to obtain the orthorectified tile. Orthorectified tiles are used to generate an orthorectified mosaic. As such, images recorded by terrestrial based camera may be used to generate a map of a road surface with corresponding road signs.

Abstract: This invention relates to a method for updating digital maps and for matching global navigation devices to a digital map. Such navigation devices rely upon GPS signals (20, 24) from satellites (22, 26). One well-documented cause of position error in navigation devices arises from the phenomenon of GPS multi-path. It has been observed that GPS multi-path errors in the latitude/longitude direction are highly correlated with errors in altitude. By comparing altitude value of GPS probe data with reference specifications for altitude, unreliable probe data (outliers) can be easily identified and culled. Such techniques can be used as well by a mobile navigation device to confirm a match to a particular road segment and if not revert to other positioning techniques such as inertial guidance systems and the like. If the local altitude is not reliably known, an estimation can be derived directly from the collected probe data.

Abstract: Example data management systems and methods are described. In one implementation, a method restores data on a first data storage node that is part of a data storage system including multiple storage nodes. The method marks multiple data entries stored in the first data storage node as dirty. A data index associated with the data storage system is received from a quorum of the data storage nodes in the data storage system. The data index is compared with data entries stored in the first data storage node. Data entries that are not contained in the data index are deleted from the first data storage node. Data entries stored in the first data storage nodes are modified to match corresponding data entries in the data storage system based on the data index.
