Abstract:
Generating a three-dimensional representation of cardiac electrical activity within a subject's heart includes collecting, from a catheter having a distal portion that includes sensors that sense electrical activity and which catheter distal portion is positioned within a cardiac chamber of a subject, data for electrical activity sensed by the catheter distal portion while positioned within the chamber of the heart. The method also includes executing an imaging algorithm on the collected electrical activity data to generate a three-dimensional representation of cardiac electrical activity within a volume of the subject including all or a portion of the subject's heart. The method further includes displaying the imaged three-dimensional cardiac electrical activity.
Abstract:
The present invention is directed to providing method and apparatus for implementing a uniform platform for data/voice service. An apparatus for implementing a uniform platform for data/voice service provided in the present invention comprises a base station controller and a Multi-BSSFast Packet Server, characterized in that said base station controller and Multi-BSSFast Packet Server are integrated into one rack, and the base station controller is connected to the Multi-BSSFast Packet Server via a link based on E1 over Ethernet (E1oE). With the technical solutions of data/voice uniform platform based on E1oE technique, network units can be smoothly transitioned from an independent network mode to a combined network mode so that the conventional technical solution that BSC can only implement Time Division Multiplexing (TDM) transmission in the system has been broken, which cause structure of the system opener and more compatible, but a separated network mode is smoothly transitioned to a combined network mode in which a rack and external E1 lines are shared between BSC and PCU as well. Meanwhile, expensive cost for using existing physical E1 lines is saved for a user and thus the cost will be decreased.
Abstract:
A computer program product being embodied on a computer readable medium for extracting semantic information about a plurality of documents being accessible via a computer network, the computer program product including computer-executable instructions for: generating a plurality of tokens from at least one of the documents, each token being indicative of a displayed item and a corresponding position; and, constructing at least one parse tree indicative of a semantic structure of the at least one document from the tokens dependently upon a grammar being indicative of presentation conventions.
Abstract:
A method for positioning in a communication network with a cellular coverage is disclosed, wherein comprising the following steps: receiving location-dependent data concerning a mobile device; from a plurality of fingerprints, each of which corresponds to one of locations within the coverage, retrieving one having the highest similarity to the location-dependent data; and determining the location corresponding to the fingerprint with the highest similarity as the mobile device's location if the highest similarity exceeds a predetermined threshold.
Abstract:
A method of data loading for large information warehouses includes performing checkpointing concurrently with data loading into an information warehouse, the checkpointing ensuring consistency among multiple tables; and recovering from a failure in the data loading using the checkpointing. A method is also disclosed for performing versioning concurrently with data loading into an information warehouse. The versioning method enables processing undo and redo operations of the data loading between a later version and a previous version. Data load failure recovery is performed without starting a data load from the beginning but rather from a latest checkpoint for data loading at an information warehouse level using a checkpoint process characterized by a state transition diagram having a multiplicity of states; and tracking state transitions among the states using a system state table.
Abstract:
The present invention relates to a method and a positioning server in a radio access network for collecting radio fingerprint positioning data records from different nodes. The data records comprise geographical positions and radio network communication parameters and are stored and grouped in clusters in the positioning server. A geometrical shape representing a geographical area based on the network communication parameters in the collected positioning data records in the cluster is computed. When a notification about changed network configuration parameters for a radio cell is received, known positioning servers simply erase all positioning data records related to that radio cell. This results in the unavailability of still valid positioning data. The present invention overcomes this problem by selectively erase positioning data records in the positioning server only when the configuration parameters have changed beyond a predefined value range.
Abstract:
Embodiments of the invention provide a method and computer program products for information retrieval from multiple documents by proximity searching for search queries. A method includes generating an index for the multiple documents, wherein the index includes words in snippets in the documents. An input search query is processed against the index by searching query terms over the snippets to introduce term proximity information implicitly in the information retrieval. Results of multiple sentence level search operations are combined as output.
Abstract:
Methods are disclosed of processing a set-level query across one or more attributes, the query being grouped by one or more attributes, whereby groups that satisfy the set-level query may be aggregated over one or more attributes. The methods use bitwise arithmetic to efficiently traverse bitmap and bit-slice vectors and indexes of a data relation to determine groups that solve the set-level query.
