20120331563 | Retrieval of Data Across Multiple Partitions of a Storage Device Using Digital Signatures - A system and method for exchanging data among partitions of a storage device is disclosed. For example, data stored in a first partition is exchanged with an application included in the first partition or with a second application included in a second partition.

A verification module included in the first partition receives a request for data and determines if the request for data is received from the first application. If the request for data is not received from the first application, the verification module determines whether the request is received from the second application and whether the global certificate is an authorized certificate. For example, the verification module determines whether the global certificate is included in a listing of authorized certificates. | 12-27-2012 |

For example, the portable computing device determines whether the application has received an input or was the primary application within a predetermined time interval from the current time. Responsive to determining the frequency of interaction with the application does not equal or exceed the threshold value, data synchronization for the application is disabled. In one embodiment, the portable computing device stops data synchronization for the application. | 08-08-2013 |

20110058609 | SYSTEM AND METHOD FOR OBJECT BASED PARAMETRIC VIDEO CODING - A video compression framework based on parametric object and background compression is proposed. At the encoder, an embodiment detects objects and segments frames into regions corresponding to the foreground object and the background. The object and the background are individually encoded using separate parametric coding techniques. While the object is encoded using the projection of coefficients to the orthonormal basis of the learnt subspace (used for appearance based object tracking), the background is characterized using an auto-regressive (AR) process model. An advantage of the proposed schemes is that the decoder structure allows for simultaneous reconstruction of object and background, thus making it amenable to the new multi-thread/multi-processor architectures. | 03-10-2011 |
