Abstract: A system and method of frame protocol classification and processing in a system for data processing (e.g., switching or routing data packets or frames). The present invention includes analyzing a portion of the frame according to predetermined tests, then storing key characteristics of the packet for use in subsequent processing of the frame. The key characteristics for the frame (or input information unit) include the type of layer 3 protocol used in the frame, the layer 2 encapsulation technique, the starting instruction address, flags indicating whether the frame uses a virtual local area network, and the identity of the data flow to which the frame belongs. Much of the analysis is preferably done using hardware so that it can be completed quickly and in a uniform time period. The stored characteristics of the frame are then used by the network processing complex in its processing of the frame. The processor is preconditioned with a starting instruction address and the location of the beginning of the layer 3 header as well as flags for the type of frame. That is, the instruction address or code entry point is used by the processor to start processing for a frame at the right place, based on the type of frame. Additional instruction addresses can be stacked and used sequentially at branches to avoid additional tests and branching instructions. Additionally, frames comprising a data flow can be processed and forwarded in the same order in which they are received.

Granted: 2008-09-23
Abstract: A dynamic fluid sealing system for a fuel injection valve (180) employs sealing-fluid to separate a gaseous fuel and a second fluid in the fuel injection valve, thereby preventing leakage of the gaseous fuel into the second fluid. A pressure-balancing system (100), which includes a pressure-balancing device (110, 111), reduces the pressure differential between the sealing-fluid and the gaseous fuel used in the injection valve. At the same time, the pressure balancing system dynamically balances the sealing-fluid pressure such that the sealing-fluid pressure is equal to or slightly greater than the pressure of the gaseous fuel within the injection valve. The pressure differential between the gaseous fuel and the sealing-fluid may be maintained throughout the operating range of engine speeds, engine loads, and fuel cut-off conditions so as to prevent leakage of compressible gaseous fuel into the second fluid. The reduced pressure differential between the gaseous fuel and the sealing-fluid also reduces leakage of sealing-fluid into the gaseous fuel.

In one example, the interconnect structure includes a ribbon of interconnect lines connecting a plurality of nodes in nonintersecting paths. The ribbon (112) of interconnect lines winds through a plurality of levels from the source level to the destination level. The number of turns of a winding decreases from the source level to the destination level. The interconnect structure further includes a plurality of columns formed by interconnect lines coupling the nodes across the ribbon in cross-section through the windings of the levels.

Abstract: The error compensating system and method is used in electric power monitorin g systems, e.g. protective relays, and includes a test unit (34) for applying a test signal to the front end of a data acquisition section of the power monitoring system and a phase reference module (30) which converts the test signal to a square wave having falling and rising edges corresponding to transitions between the positive and negative portions of the test signal. A programmable logic device (20) determines the zero crossings of the sampled digital signal from the data acquisition system and then determines the time difference between a falling edge of the module output signal and the zero crossing (52) of the sampled digital signal. The time difference (54) is representative of the phase shift produced by the data acquisition component s (16,18). A compensation circuit adjusts the digitally sampled signals with t he amount of the determined phase shift.
