20080226301 | System and Method For Increasing Spectral Efficiency, Capacity and/or Dispersion-Limited Reach of Modulated Signals in Communication Links - A system and method for increasing spectral efficiency, capacity and/or extending dispersion-limited reach in a communication link employs narrow filtering of a baseband signal to reduce the original bandwidth to a substantially smaller bandwidth for transmission across a transmission medium such as an optical fiber. By restricting the bandwidth, the rate of spreading is reduced significantly. The receiver at the other end of the transmission medium includes an equalizer for returning the received signal to its original bandwidth for retrieval of information contained in the signal. | 09-18-2008 |

20080250396 | Transforming Locks in Software Loops - An improved system and computer programming product for acquisition and release of locks within a software program is disclosed. In an exemplary embodiment, a lock within a loop is transformed by relocating acquisition and release instructions from within the loop to positions outside the loop. This may significantly decrease unnecessarily lock acquisition and release during execution of the software program. In order to avoid contention problems which may arise from acquiring and keeping a lock on an object over a relatively long period of time, a contention test may be inserted into the loop.

The read-only object is formed to delay copying of the immutable object until a runtime determination is made that a write to the immutable object will be made. In response to an attempt to write to the read-only object, an internal value of the read-only object is copied to read-and-write storage using runtime information to form a writable copy of the read-only object. A set of references for the read-only object is updated to point to the writable copy of the read-only object.

A computer implemented method, data processing system and computer program product provide a capability where only if one of the writing paths executes will a full writer lock be acquired. Illustrative embodiments may be used to create two copies of the critical section comprising a reading version and a writing version. The default execution leads to the reader version, which only acquires a reader-lock. The reader version of the code executes prior to execution of the writer lock only version, otherwise bypassing the writer lock only version. If the execution leads to a path in which a write would occur, the reader only version branches to the beginning of the writer version. The writer version is identical to the original code and obtains a full writer lock. If execution in the reader lock does not lead to a path that writes, then only the reader lock is acquired. | 04-02-2009 |

20130291754 | Pressure Discharge Valve - The present invention relates in general to a pressure discharge mechanism for closed vessels having an internal chamber designed to hold volatile and/or explosive substances in a sealed manner comprised of an at least one eutectic composition and a threaded joint designed to open or vent the closed vessel when the contents of the closed vessel reaches a predetermined temperature while maintaining full structural integrity during normal operation. In one aspect, the closed vessel is a munitions casing which functions as intended under normal operating environments, but then when exposed to extreme temperatures, reduces the munition's high order explosion capability, and is transformed into a safe, low order reaction with significantly less reactive potential. In one aspect, the closed vessel is a transport tanker which should not release substances contained therein. However, if the tanker catches fire, the pressure relief mechanism of the present invention reduces risk of explosion. | 11-07-2013 |

20110222769 | DOCUMENT PAGE SEGMENTATION IN OPTICAL CHARACTER RECOGNITION - Page segmentation in an optical character recognition process is performed to detect textual objects and/or image objects. Textual objects in an input gray scale image are detected by selecting candidates for native lines which are sets of horizontally neighboring connected components (i.e., subsets of image pixels where each pixel from the set is connected with all remaining pixels from the set) having similar vertical statistics defined by values of baseline (the line upon which most text characters “sit”) and mean line (the line under which most of the characters “hang”). Binary classification is performed on the native line candidates to classify them as textual or non-textual through examination of any embedded regularity. Image objects are indirectly detected by detecting the image's background using the detected text to define the background. Once the background is detected, what remains (i.e., the non-background) is an image object. | 09-15-2011 |
20110280481 | USER CORRECTION OF ERRORS ARISING IN A TEXTUAL DOCUMENT UNDERGOING OPTICAL CHARACTER RECOGNITION (OCR) PROCESS - An electronic model of the image document is created by undergoing an OCR process.

The electronic model serves as input information which is supplied to each of the stages by a previous stage that processed the image document. A graphical user interface is presented to the user so that the user can provide user input data correcting a mischaracterized item appearing in the document. Based on the user input data, the processing stage which produced the initial error that gave rise to the mischaracterized item corrects the initial error. Stages of the OCR process subsequent to this stage then correct any consequential errors arising in their respective stages as a result of the initial error. | 11-17-2011 |

20130179650 | DATA SHARING USING DIFFERENCE-ON-WRITE - When a virtual machine writes to a page that is being shared across VMs, a share value is calculated to determine how different the page would be if the write command were implemented. If the share value is below a predefined threshold (meaning that the page would not be “too different”), then the page is not copied (as it would be in a standard copy-on-write operation). Instead, the difference between the contents of the pages is stored as a self-contained delta. The physical to machine memory map is updated to point to the delta, and the delta contains a pointer to the original page. When the VM needs to access the page that was stored as a delta, the delta and the page are then fetched from memory and the page is reconstructed. | 07-11-2013 |
