20100106858 | METHOD FOR LOSSLESS COMPRESSION FOR NMS NETWORK ALARMS - The claimed subject matter relates to an architecture that can provide substantially lossless compression and subsequent decompression of messages at an application level. In particular, the architecture, in one aspect thereof, can receive a set of messages. When application data for received messages does not match stored message, the message can be stored to a buffer. In contrast, if application data matches that for a stored message, the received message can be discarded and a message count incremented. The compressed message pattern can include the stored message and the message count. Upon decompression, the number of messages received can be identified by the message count and the application data can be readily recreated for all messages by copying that data. Non-application data, such as time stamp information can be reconstructed based upon a buffer period, other timing offset data, or other data fields included in the message pattern. | 04-29-2010 |
20100115135 | AGGREGATE CONTROL FOR APPLICATION-LEVEL COMPRESSION - The claimed subject matter relates to an architecture that can actively regulate associated gateways in connection with lossless application-level compression. In particular, the architecture can monitor a flow of messages that enter and/or traverse a gateway in order to determine a bandwidth utilization of an associated network due to the messages. The architecture can also monitor the aggregate messages load for the associated network due to all gateways. In particular, the architecture can regulate lossless application-level compression at that gateway or all of the gateways in the set as a function of the bandwidth utilization and/or the aggregate message load. Accordingly, compression features can be activated or deactivated based upon a utilization threshold parameter, and gateways can be regulated uniformly or independently from one another. | 05-06-2010 |

20120074329 | DIGITAL X-RAY DETECTOR WITH INCREASED DYNAMIC RANGE - In one embodiment, a digital X-ray detector is provided with a plurality of pixel regions. Each pixel region includes a first photodiode having a first area and a second photodiode having a second area equal to or smaller than the first area. The digital X-ray detector also includes a shielding structure that overlies the first and second photodiodes of each pixel region with the shielding structure shielding proportionally less of the first photodiode than of the second photodiode to provide the first photodiode with a first sensitivity and the second photodiode with a second sensitivity lower than the first sensitivity. | 03-29-2012 |
