Filed:

Jun 30, 2005

Appl. No.:

11/173817

Inventors:

David V. Hobbs - Surrey, CA
Bill Lin - San Diego CA, US

Assignee:

Teradici Corporation - Burnaby, British Columbia

International Classification:

G06F 15/00
G06F 12/02

US Classification:

358 115, 345543

Abstract:

A method and apparatus for comparing portions of data from a digital raster signal to a plurality of scan blocks of data, where each scan block in the plurality describes either a defined image area or entire image frame is disclosed. Included are a hashing function that calculates hash codes for spatially-defined segments of an incoming raster signal; a recent scan hash table containing hash codes for scan blocks received within a specified time period; a comparator for comparing calculated hash codes for the spatially-defined segments of the incoming raster signal with hash codes stored in the recent scan hash table; a pixel capture and timing module for capturing a digital raster signal; and an output selector for selecting for transmission a compressed form of a scan block, a hash code index, or no data if a scan block exists in a remote frame playout buffer.

US Classification:

370231, 370236, 370241, 370252, 370255, 709224, 726 7

Abstract:

A system for protecting a network from a traffic surge includes a data collection module, an allocation module, and a traffic flow module. The data collection module is configured to obtain network utilization information for a plurality of traffic flows. The allocation module is configured to determine a bandwidth allocation to minimize a drop probability for the plurality of traffic flows. The traffic flow module is configured to preferentially drop network packets for a traffic flow exceeding the optimal bandwidth allocation.

International Classification:

G06F 11/00

US Classification:

726 23, 370401, 359167

Abstract:

A method includes determining, at a network routing device, an average packet drop rate for a plurality of aggregations of packet flows. The method also determines a threshold packet drop rate based on the average packet drop rate, a current packet drop rate for a select aggregation of the plurality of aggregations, and whether at least one packet flow of the select aggregation is potentially subject to a denial-of-service attack based on a comparison of the current packet drop rate to the threshold packet drop rate.

Abstract:

A system for protecting a network from a traffic surge includes a data collection module, an allocation module, and a traffic flow module. The data collection module is configured to obtain network utilization information for a plurality of traffic flows. The allocation module is configured to determine an optimal bandwidth allocation for each of the plurality of traffic flows. The traffic flow module is configured to preferentially drop network packets for a traffic flow exceeding the optimal bandwidth allocation.

Filed:

Jan 24, 1994

Appl. No.:

8/185544

Inventors:

Haruki Takahashi - San Diego CA
Bill Lin - San Diego CA

Assignee:

Sony Electronics Inc.

International Classification:

B08B 302

US Classification:

134 56R

Abstract:

A system which enables removal of phosphor from a CRT front panel flange. The system includes an air operated valve connected between a water supply and a nozzle. The air operated valve may be incrementally opened and closed, which enables a continuous stream of water to be discharged from the nozzle onto the phosphor to remove the phosphor. In addition, the system includes an air supply and a pair of speed controllers which control the rate at which the air operated valve opens and closes.
