| 20080260240 | User interface for inputting two-dimensional structure for recognition - In embodiments consistent with the subject matter of this disclosure, a user may input one or more strokes as digital ink to a processing device. The processing device may produce and present a recognition result, which may include a misrecognized portion. A user may indicate a desire to correct the misrecognized portion and may further select one or more strokes of the misrecognized portion. The processing device may then present the one or more recognition alternates corresponding to the selected one or more strokes of the misrecognized portion. In some embodiments, the processing device may permit a user to rewrite the selected one or more strokes of the misrecognized portion with newly entered digital ink. Features, such as, rewriting and correction of the input digital ink may be discoverable in some embodiments. | 10-23-2008 |

| 20110219962 | YARD WASTE COMPACTOR - A compactor for compressing yard waste in a yard waste receptacle such as a leaf bag or garbage pail is disclosed. The compactor includes a press and a handle connected to the press. Force may be applied to the handle to cause the press to compress the yard waste in the yard waste receptacle so as to compact the yard waste and allow more yard waste to be added to the receptacle. A locking swivel bracket may be used to connect the handle to the press. The locking swivel bracket allows the handle to be held in a substantially perpendicular position for use in compacting yard waste or a substantially parallel position for storing the compactor or for guiding yard waste into a yard waste receptacle. | 09-15-2011 |

| 20110188395 | Single Sensor Radio Scene Analysis for Packet Based Radio Signals using 2nd and 4th Order Statistics - We consider a problem of radio frequency (RF) signal analysis where one sensing node observes a frequency band possibly used by multiple packet based radio transmitters. Analysis of the received signal includes two steps. In the first step we use a spectrogram to perform temporal segmentation of the received nonstationary signal. This task may be formulated as a clustering problem. In the second step we compute a certain 2-D slice of the fourth order spectrum for each of the segments found in the first step. These fourth order spectrum slices are arraigned in a three-way array. One aspect of the second step is to use uniqueness properties of the low rank decomposition of the three-way array to recover spectra and associated activity sequences of individual components in the received signal. We derive a numerical algorithm for the low rank decomposition, which computes estimates of the spectra and activity sequences by optimizing certain weighted least squares criterion under application specific constraints. Certain embodiments are illustrated with simulation examples involving signals used in 802.11a/b/g and Bluetooth networks. The disclosed methods and related systems can be used as spectrum analysis tools, providing crucial information needed for achieving efficient utilization of radio spectrum and elimination of mutual interference between the coexisting systems. | 08-04-2011 |

| 20080276229 | INCREMENTAL MODEL REFINEMENT AND TRANSFORMATION IN GENERATING COMMERCE APPLICATIONS USING A MODEL DRIVEN ARCHITECTURE - In one embodiment of the invention, a method for profile mapped model transformation for model driven architecture (MDA) development of service provisioning applications can be provided. Them method can include mapping elements of a platform independent domain specific model to a platform specific domain specific model for a target platform with stereotypes in a uniform modeling language (UML) profile defined for the target platform. The method further can include transforming a platform independent domain specific model into a platform specific domain specific model for a target platform by applying the stereotypes of the UML profile defined for the target platform. Finally, the method can include generating shell source code for the transformed platform specific domain specific model. | 11-06-2008 |

| 20110149657 | Methods and Apparatus for Write-Side Intercell Interference Mitigation in Flash Memories - Methods and apparatus are provided for write-side intercell interference mitigation in flash memories. A flash memory device is written by obtaining program data to be written to at least one target cell in the flash memory; obtaining one or more bits of program data for at least one aggressor cell to be programmed later than the target cell: and precompensating for intercell interference for the target cell by generating precompensated program values. The aggressor cells comprise one or more cells adjacent to the target cell, such as adjacent cells in a same wordline as the target cell and/or cells in an upper or lower adjacent wordline to the target cell. The precompensated program values for the target cell are optionally provided to the flash memory. | 06-23-2011 |

| 20110216586 | Methods And Apparatus For Intercell Interference Mitigation Using Modulation Coding - Methods and apparatus are provided for intercell interference mitigation using modulation coding. During programming of a flash memory, a modulation encoding is performed that selects one or more levels for programming the flash memory such that a reduced number of cells in the flash memory are programmed with a value that violates one or more predefined criteria.
