Abstract: The present invention relates a dynamic voltage restorer (DVR) system and methods for addressing voltage dips. The instant DVR incorporates high frequency technology, such as a high frequency transformer, to generate a square wave voltage from a storage device, such square wave being modulated prior to being delivered to a load. The generation of the square wave and modulation thereto creates a voltage that reacts fast to voltage dips, while addressing wide ranging harmonics usually present in square waves.

Abstract: A method and system is disclosed for regenerating a particulate filter for an exhaust system. A source of hydrocarbon is injected into the exhaust flow upstream of the filter. The injected hydrocarbon within the filter is caused to oxidize and a temperature within the filter to rise, the temperature rise being initiated at a downstream end of the filter. A temperature change at the filter is sensed in response to the oxidation of the hydrocarbon. The amount of hydrocarbon being injected into the filter is adjusted to increase the temperature within the filter above a defined threshold from the downstream end to an upstream end of the filter, the defined threshold temperature being sufficient to oxidize soot. An operational parameter indicative of the filter regeneration being complete is sensed, and further injection of the hydrocarbon into the exhaust flow is prevented in response to the sensed operational parameter.

Abstract: A lean NOx trap operating in a lean NOx exhaust stream is progressively regenerated, sector to sector, for efficient operation of the trap and conservation of reducing gas used in the regeneration. A reductant gas distributor is inserted in the exhaust upstream of the trap. Reductant gas is carried into the exhaust duct through a conduit portion and the reductant gas stream diverged and directed through a distributor into selected cells of the trap. The NOx in the selected cells is reduced to N2 while lean NOx exhaust continues to flow through the remainder of the trap. By relative movement of the reductant gas distributor and the trap, the entire trap is progressively and continually regenerated while still preforming as a NOx trap.

The protocol processor (44) receives IP packets (24) transmitted over the communications medium (26). Operating system (OS) software executing on the CPU (46) controls the operation of the protocol processor (44) via a host interface (57) and a dual port RAM (58). A switch (50) routes RTP type IP packets to a RTP handler module (48) running on the protocol processor (44). The RTP packet handler module (48) processes RTP packets. Non-RTP packets are processed by the OS software (46).
