20130238975 | OFF-LINE PRESENTATION OF WEB CONTENT - An enhanced reader can provide a user with an off-line browsing experience that is essentially indistinguishable from an on-line browsing experience. In particular, the enhanced reader can allow a user to access essentially all elements (e.g. hypertext elements) in a selected page of web content as well as navigation information such as next/previous page. The user can use the navigation information to view web content in its original form as well as navigate from page to page in those situations where the web content spans more than one page. This off-line navigation experience can be enabled by software that automatically archives web content as part of a background process while a user's device is in an on-line state. In this way, the user's off-line and on-line browsing experiences are substantially indistinguishable from each other. | 09-12-2013 |

20130275853 | METHOD FOR IMPROVING BACKWARD/FORWARD PERFORMANCE BETWEEN CERTAIN TYPES OF DYNAMIC WEB PAGES - A method for improving backward and forward web browser performance is described. In one embodiment, backward and forward web performance is enhanced by ignoring unload handler scripts and caching web pages. Web elements with unload handler scripts are examined. In a first pass, if the web page elements are not determined to be significant, then the related unload handler scripts can be ignored, enabling the web page to be cached. In a second pass, if the web page element is significant, but the unload handler script is determined to be insignificant, then the unload handler script can be ignored and the web page can be cached. | 10-17-2013 |

In another embodiment, a web page can be constructed from web archive data. This constructed web page may not be displayed, but can be inspected for substantially similar elements so that those elements can be removed. After the elements are removed, then the web page can be displayed to a user. Either embodiment can be used alone or in parallel to reduce the appearance of substantially similar elements within a web page constructed from a web archive. | 06-19-2014 |

20150332372 | System and Method for Context-Aware Recommendation through User Activity Change Detection - Example systems and methods for context-aware recommendation generation are described. In one implementation, item models are built using user preference data of multiple users and item information of multiple items. When a recommendation request corresponding to a user is received, the profile of that user is retrieved from the user profile database. Given the profile of the user and the item models, utility scores are then computed for the candidate items. Our system exploits a novel approach to detect any sudden and significant changes in the preference data of the given user. If a change is detected, the utility scores are adapted to prioritize the user's most recent preferences. The computed utility scores are used as the basis for ranking the items. A subset of items with highest scores is then selected as recommendations and is presented to the user. | 11-19-2015 |

In addition, the delatching pull tab obviates the need for pins or screws, thereby improving manufacturing yield by reducing the likelihood that the module will be damaged during the manufacturing process. In addition, by eliminating pins or screws and a bail from the design, there are fewer moving parts that can wear out over time. | 10-04-2012 |

20110134703 | Nonvolatile Memory and Method With Reduced Program Verify by Ignoring Fastest And/Or Slowest Programming Bits - A group of non-volatile memory cells are programmed in a programming pass by a series of incremental programming pulses where each pulse is followed by a program-verify and possibly program-inhibition step. Performance is improved during the programming pass by delayed starting and prematurely terminating the various verify levels that demarcate the multiple memory states. This amounts to skipping the verifying and inhibiting steps of the fastest and slowest programming (fringe) cells of the group. A reference pulse is established when the fastest cells have all been program-verified relative to a first verify level. The starting of what verify level at what pulse will then be delayed relative to the reference pulse. Verifying stops for a given verify level when only a predetermined number of cells remain unverified relative to that given level. Any errors arising from over- or under-programming of the fringe cells are corrected by an error correction code. | 06-09-2011 |

20080253185 | Non-Volatile Memory and Method with Control Gate Compensation for Source Line Bias Errors - Source line bias is an error introduced by a non-zero resistance in the ground loop of the read/write circuits. During sensing the source of a memory cell is erroneously biased by a voltage drop across the resistance and results in errors in the applied control gate and drain voltages. This error is minimized when the applied control gate and drain voltages have their reference point located as close as possible to the sources of the memory cells. In one preferred embodiment, the reference point is located at a node where the source control signal is applied. When a memory array is organized in pages of memory cells that are sensed in parallel, with the sources in each page coupled to a page source line, the reference point is selected to be at the page source line of a selected page via a multiplexor. | 10-16-2008 |

The multiple read/write circuits are organized into a bank of similar stacks of components. Redundant circuits such as a processor for processing data among stacks each associated with multiple memory cells are factored out. The processor is implemented with an input logic, a latch and an output logic. The input logic can transform the data received from either the sense amplifier or the data latches.

20100091568 | Nonvolatile Memory and Method With Reduced Program Verify by Ignoring Fastest and/or Slowest Programming Bits - A group of non-volatile memory cells are programmed in a programming pass by a series of incremental programming pulses where each pulse is followed by a program-verify and possibly program-inhibition step. Performance is improved during the programming pass by delayed starting and prematurely terminating the various verify levels that demarcate the multiple memory states. This amounts to skipping the verifying and inhibiting steps of the fastest and slowest programming (fringe) cells of the group. A reference pulse is established when the fastest cells have all been program-verified relative to a first verify level. The starting of what verify level at what pulse will then be delayed relative to the reference pulse. Verifying stops for a given verify level when only a predetermined number of cells remain unverified relative to that given level. Any errors arising from over- or under-programming of the fringe cells are corrected by an error correction code. | 04-15-2010 |
