20140215170 | Block Compression in a Key/Value Store - System and method embodiments are provided for improving the performance of data compression for storage systems. The embodiments enable selectively compressing data for storage on a block by block basis to save resources and computation time and cost. The system and method also handle the compression of different types of data blocks using different targeted algorithms. In an embodiment, a method for compressing data in a storage system includes receiving one or more data blocks for storage, determining whether to compress one or more data blocks according to attributes of the one or more data blocks, upon determining to compress a data block from the one or more data blocks, compressing the data block, and storing the compressed data block. The attributes include at least one of a name of the data block, a file type of the data block, and information in the data block. | 07-31-2014 |
20140270153 | System and Method for Content Encryption in a Key/Value Store - System and method embodiments are provided for content encryption in a key/value store. The embodiments include encrypting both the key and value of client data blocks for storage so that the data can be retrieved reliability without compromising the key. An embodiment method includes obtaining a key from a data block comprising the key and a value, encrypting the key using a deterministic encryption algorithm with an encryption key to map the key to a cypher text in a one-to-one mapping, and encrypting the value using a second encryption algorithm to randomly map the value to a second cypher text. Encrypting both the key and the value provides more protection to the client data instead of encrypting only the value and leaving the key vulnerable without encryption. The encrypted key can also be protected from unauthorized access and from the owner of the database or the storage system. | 09-18-2014 |
20140279946 | System and Method for Automatic Integrity Checks in a Key/Value Store - System and method embodiments are provided for integrity check and recovery in a key/value store. An embodiment method includes receiving a command to retrieve a data block stored in the key-value store system, the command indicating a key associated with the data block. The method further includes retrieving one or more copies of the stored data block including the key, a value, a data integrity check algorithm, and an integrity value, and performing data integrity check on the retrieved one or more copies of the data block using the data integrity check algorithm, the integrity value, and at least one of the key and the value. Upon one or more copies of the data block failing the data integrity check, the one or more copies of the data block are repaired and the data block is delivered. | 09-18-2014 |

20090021695 | Display of Ocular Movement - Ocular movement of a subject is displayed in one or more windows of a user interface allowing a technician and/or clinician to observe the ocular movement such as to properly administer various tests for visual, vestibular, and neurological disorders as well as for diagnosing such disorders. When displaying the ocular movement, the video of the ocular movement being displayed may be panned to adjust the position of each eye within a display window as desired, such as to center the pupils and to provide a common horizontal location for both left and right pupils. Additionally, zooming in or out on the video of ocular movement may be provided to allow artifacts of the video stream to be effectively cropped from the display window and to allow the details of the ocular movement to be adequately visible. Furthermore, the display window size may be increased such that the details of the ocular movement are enlarged to allow the clinician and/or technician to better see those details even from a distance. | 01-22-2009 |
20100014586 | FRAME DECIMATION THROUGH FRAME SIMPLICATION - System and method of providing improved signal compression using frame decimation through frame simplification and generating an encoded bitstream of video frames therefrom are disclosed. The encoding method comprises zeroing a difference frame generated by an encoder by using a feedback loop that injects a reconstructed frame, generated by the encoder of the difference frame, as a next frame of the video frames to be processed by the encoder. The encoding system comprises an input configured to provide a stream of video frames; a first process configured to generate a difference frame, and a second process configured to generate a reconstructed frame. A feedback loop of the system is configured to inject a generated reconstructed frame from the second process of a generated difference frame from the first process as a next frame of the video frames in the stream to be processed into the encoded bitstream by the encoding system. | 01-21-2010 |
