20110207093 | HANDHELD BRAILLE CONVERTING DEVICE, BRAILLE CONVERTING METHOD, AND BRAILLE CONVERTING PROGRAM - When a user positions a handheld Braille converting device on an object, a CCD camera captures an image of a predetermined range around it. The presence/absence of character(s) is detected based on the captured image. When the characters exist, the characters are recognized, and the recognized characters are converted to Braille and displayed. When the relative position between the moving direction of the handheld Braille converting device and the character string existing in the captured image is not correct, an error is displayed. | 08-25-2011 |
20120236134 | HANDHELD BRAILLE CONVERTING DEVICE, BRAILLE CONVERTING METHOD, BRAILLE CONVERTING PROGRAM, AND STORAGE MEDIUM - A handheld Braille converting device includes a Braille display unit, an image capturing element, a character recognition element, a Braille converting element, and a display control element to complete the process from the reading of the characters to the output of the Braille by itself. Also, the device has a size capable of being held by a single hand. The Braille display unit includes multiple single Braille display units each corresponding to one Braille character and each single Braille display unit includes multiple movable members. The display control element displays whether or not the relative position of the handheld Braille converting device is correct with respect to a character or character string existing in the captured image, by operating members included in a part of the single Braille display units. The display control element also displays Braille by operating members included in the other single Braille display units. | 09-20-2012 |

20080317327 | Method of Design Analysis of Existing Integrated Circuits - The present invention involves a computationally efficient method of determining the locations of standard cells in an image of an IC layout. The initial step extracts and characterizes points of interest of the image. A coarse localization of possible standard cell locations is performed and is based on a comparison of the points of interest of an instance of an extracted standard cell and the remaining points of interest in the image. A more rigid comparison is made on the list of possible locations comprising a coarse match and a fine match. The coarse match results in a shortlist of possible locations. The fine match performs comparisons between the template and the shortlist. Further filtering is done to remove the effects of noise and texture variations and statistics on the results are generated to achieve the locations of the standard cells on the IC layout. | 12-25-2008 |

20090063560 | METHOD AND SYSTEM FOR PATENT CLAIM MANAGEMENT AND ORGANIZATION - A method and system for organizing and managing claim elements and reference objects is disclosed. The method and system establish database links between claim elements and reference objects based on associations identified between them. These database links are then stored in the database for future reference. The links are also used to derive additional associations between other claim elements and reference objects. The method and the system also enable the displaying of claim elements and reference objects to users in a way that illustrates the associations between the claim elements and reference objects. Associations may be defined based on similarities or dissimilarities between claim elements and reference objects, and amongst claim elements and reference objects, respectively. | 03-05-2009 |
20090092285 | METHOD OF LOCAL TRACING OF CONNECTIVITY AND SCHEMATIC REPRESENTATIONS PRODUCED THEREFROM - A schematic diagram detailing a circuit that was reverse engineered from a plurality of images taken of the circuit is provided. The schematic diagram includes at least one circuit element that was represented as an object in at least one of the plurality of images, such that signal continuity information was determined through local tracing of connectivity between a first image and a second image of the plurality of images. A method of tracing the connectivity within the plurality of images to produce the schematic diagram is also disclosed. | 04-09-2009 |
20100325593 | INTEGRATED CIRCUIT ANALYSIS SYSTEMS AND METHODS - The current invention uses structural data mining methods and systems, combined with partitioning hints and heuristics, to locate high level library functional blocks in a gate level netlist of an integrated circuit (IC). In one embodiment of the invention, the library is created by synthesizing various design blocks and constraints. The method supports characterization matching between a netlist and a library, between libraries and between netlists. The data mining method described herein uses a subgraph growing method to progressively characterize the graph representation of the netlist of the IC. In one embodiment of the invention, alternative hashing is used to perform subgraph characterization. Further, the located high level functional blocks may be used to substitute the corresponding portions of the target netlist having the matched characterizations, and may be annotated accordingly in the resulting netlist. | 12-23-2010 |

20140098572 | FORWARD BOOST POWER CONVERTERS AND METHODS - Forward boost power converters, and related methods, are disclosed. In a switching mode power converter coupled between a first terminal pair and a second terminal pair, a first inductance is coupled to a first switch in a first circuit path across the first terminal pair. A capacitance is coupled to a second inductance in a second circuit path, and to the first inductance in a third circuit path. During their respective conduction periods, the first switch couples the first inductance across the first terminal pair, a second switch completes a circuit between the second terminal pair and one of: the second circuit path or the third circuit path, and a third switch completes the other of: the second circuit path and the third circuit path. Energy transfer involves both substantially linearly varying currents and substantially half sinusoidal current pulses. | 04-10-2014 |
20140118014 | POWER GENERATING COMPONENT CONNECTIVITY RESISTANCE - Power generating component connectivity resistance monitoring techniques are disclosed. In an array of power generating components that are connected in parallel to a power bus, a power generating component measures an output current that it supplies to the power bus. Respective first and second power generating components measure a first voltage at an output of the first power generating component and a second voltage at an output of the second power generating component. A resistance in the array between first and second connection points in the array through which the output current flows is determined based on the measurements of the output current, the first voltage, and the second voltage. | 05-01-2014 |

A determination is made as to whether a reconnect condition, for reconnecting a PV panel to a power system from which the PV panel is disconnected, is satisfied. The PV panel is automatically reconnected to the power system responsive to determining that the reconnect condition is satisfied. A determination is then made as to whether a power system operating condition is satisfied on reconnection of the PV panel, and the PV panel is automatically disconnected from the power system responsive to determining that the power system operating condition is not satisfied on reconnection of the PV panel. | 09-18-2014 |
