A formatting tool enables “smart” copy and paste functions. The “smart” copy and paste functions can be invoked in a context-sensitive manner, depending on the conditions under which the copy and paste functions are implemented. The present invention will automatically include in a selection a paragraph marker at the end of a selected paragraph, if every other textual character in the paragraph has been selected. The present invention will discard a paragraph mark that is included in pasted text if the pasted text is pasted into the middle of another paragraph, indicating that the user prefers the formatting of the pasted-into paragraph. The present invention also reduces inconsistencies in formatting styles that may exist between source and target documents automatically redefining a style in the target document to conform to a corresponding style in the source document. The present invention also automatically adjusts paragraph spacing, in response to text being pasted into a target document. In response to various scenarios, the present invention will determine the most likely paragraph spacing intended by the user and will apply the most probable paragraph spacing to the pasted paragraph. The present invention also automatically adjusts list, table, and spreadsheet formatting, in response to such document elements being pasted into a differently-formatted target document. Finally, the present invention provides a convenient recovery dialog that may be invoked to alter any automatically-implemented formatting decisions.

An iterative decoder dynamically controls the number of local iterations of error-correction decoding performed for each global iteration of channel detection. In so doing, the iterative decoder (i) limits the number of local iterations that are performed after error-correction decoding has likely encountered a trapping set and (ii) permits decoding to continue when error-correction decoding is on the path to converging on a valid codeword.

A distributed object store in a network storage system uses location-independent global object identifiers (IDs) for stored data objects. The global object ID enables a data object to be seamlessly moved from one location to another without affecting clients of the storage system, i.e., “transparent migration”. The global object ID can be part of a multilevel object handle, which also can include a location ID indicating the specific location at which the data object is stored, and a policy ID identifying a set of data management policies associated with the data object. The policy ID may be associated with the data object by a client of the storage system, for example when the client creates the object, thus allowing “inline” policy management. An object location subsystem (OLS) can be used to locate an object when a client request does not contain a valid location ID for the object.

Consistent with the present disclosure, an optical receiver is paired with an optical transmitter in a transceiver card or module, for example. During normal operation, the optical transmitter supplies optical signals for downstream transmission on a first optical communication path, and the optical receiver receives additional optical signals from a second optical communication path. During a transmitter monitoring mode (or “loopback”), however, when monitoring of transmitter parameters is desired, an optical switch directs the output or portion thereof from the transmitter to the receiver. The receiver may then supply monitoring data or information to a control or processor circuit, which, in turn, may supply control signals to the transmitter. In response to such control signals, the performance of the transmitter may be optimized, for example, by reducing BER and/or OSNR to a desired level. The switch is then configured to block transmission of the transmitter output or portion and normal operation is commenced. Thus, consistent with the present disclosure, an optical receiver is provided to detect optical signals inbound on one optical communication path during normal operation is also used to receive optical signals directly from the transmitter during the monitoring mode. Accordingly, a dedicated monitoring receiver is not required and the system is rendered less expensive, power consumption may be minimized and space may be conserved.

The present invention relates to minimally invasive X-ray guided interventions, in particular to an image processing and rendering system and a method for improving visibility and supporting automatic detection and tracking of interventional tools that are used in electrophysiological procedures.

After registration of the projected 3D data with each of said X-ray images, comparison of the 2D projected image data with the 2D fluoroscopic images—based on the resulting difference images—allows removing common patterns and thus enhancing the visibility of interventional instruments which are inserted into a pathological tissue region, a blood vessel segment or any other region of interest in the interior of the patient's body.

Once the 2D-3D registration is completed for a given view, all the changes in the system geometry of an X-ray system used for generating said fluoroscopic images can be applied to a registration matrix. Hence, use of said method as claimed is not limited to the same X-ray view during the whole procedure.

An input voltage detection unit detects whether an AC input voltage is the voltage of a 100V system or of a 200V system. In response, a frequency decreasing gain setting unit switches between frequency decreasing gain characteristics relative to load factors. The frequency decreasing gain characteristics are established so that the initiation of a decrease in a feed back signal in the 100V system is earlier than that in the 200V system. By switching the frequency decreasing gain characteristics based on an AC input signal, the characteristics, in which a decrease in a feed back signal in the 200V system is earlier than that in the 100V system, are cancelled to allow load factors, at each of which a power supply operation frequency reaches the audible region, to be approximately the same to enable a vibration isolating measure to be independent of the AC input voltage.
