Abstract: An exhaust gas aftertreatment system for treating an engine-out exhaust gas feedstream of a spark-ignition direct-injection engine includes a multi-stage catalytic converter comprising a converter inlet, a converter outlet, and a substrate having a first end associated with the converter inlet and a second end associated with the converter outlet. The substrate further includes a multiplicity of flow passages between the first and second ends of the substrate, a first surface location corresponding to the first end of the substrate, and a second surface location corresponding to the second end of the substrate. A first washcoat stage is applied to the substrate at the first surface location corresponding to the first end of the substrate. A second washcoat stage is applied to the substrate at the second surface location corresponding to the second end of the substrate. The first and second washcoat stages include washcoats formulated to generate hydrogen and ammonia from the engine-out exhaust gas feedstream.

Abstract: An exhaust aftertreatment system for a lean-burn engine may include a lean NOx trap that comprises a catalyst material. The catalyst material may remove NOx gases from the engine-out exhaust emitted from the lean-burn engine. The catalyst material may include a NOx oxidation catalyst that comprises a perovskite compound.

Abstract: A sulfur tolerant oxidation catalyst with appreciable NO and HC oxidation capabilities has been developed for use in any component of an exhaust aftertreatment system for a lean-burn engine where the oxidation of at least NO is desired. Several non-exclusive examples of such components where the oxidation catalyst may be employed include a DOC and a LNT. The oxidation catalyst may comprise perovskite oxide particles that support palladium particles. The ability of the palladium supported perovskite oxide particles to concurrently oxidize NO and HC's can significantly diminish or altogether eliminate the use of platinum in the exhaust aftertreatment system for at least NO oxidation. The oxidation catalyst, moreover, may exhibit superior thermal durability and better NO and HC oxidation activities than platinum in some instances.

Abstract: An optical receiver is provided with inputs for receiving two fiber optic lines. The two fiber optic lines carry redundant data. An optical interface passes the respective signals therein to a comparison unit.

Clock data for operating the comparison unit is extracted from the optical signals.

Abstract: Catalysts for the water gas shift reaction contain a variety of late transition metals. The catalytic compositions contain a late transition metal carried on a support which is a carbide, nitride, or mixed carbide nitride of a group 6 metal such as molybdenum, tungsten, and mixtures thereof. The late transition metal includes ruthenium, cobalt, nickel, palladium, platinum, copper, silver, or gold. The water gas shift reaction may be catalyzed by contacting a gaseous stream containing carbon monoxide and water with such a solid catalyst composition. In some embodiments, the catalysts are several times more active than known commercial catalysts for the water gas shift reaction.

Abstract: A method and circuit for performing a wired-or function in a differential transmission environment are disclosed. The wired-or function is realized by enabling the differential driver portion of the differential transceiver when the signaling path is to be driven with a logical true signal and disabling the differential driver portion when a logical false signal is to transmitted to the signaling path. In a preferred embodiment, a 1394 backplane node (a node is a single connection to the bus which may or may not be shared by multiple devices) is implemented using commercially available chips including a physical arbiter, a link controller, a differential transceiver, a programmable logic device, and some additional transistors.

Abstract: A method and apparatus for measuring and controlling the temperature of a semiconductor device is described. The temperature of a semiconductor device is controlled by measuring the temperature at the semiconductor device and adjusting the temperature by supplying a coolant to the semiconductor device over a coolant line. The amount of coolant which flows to the semiconductor device is controlled by a solenoid switch connected to a valve in the coolant line. A system for measuring and controlling the temperatures of multiple semiconductor devices is also described.

Abstract: Each link between components connected in a daisy-chain configuration is also connected to a special router that can be configured to bypass any one or more of the components. In this way, one or more failed components can be isolated from the daisy-chain configuration without affecting the ability of the other operational components to continue to operate properly. In one embodiment, the special router has a configuration of horizontal and vertical switches and delay nodes. The switches can be independently and selectively controlled to isolate one or more of the components from the daisy-chain configuration, while the delay nodes delay transmission of the signals to simulate the processing time of the bypassed components. In this way, interference with the processing of the remaining operational components can be minimized.

Abstract: An interface between a parallel backplane bus of a physical layer of a communication device and a higher layer of the device is provided in a manner compatible with a serial bus architecture such as IEEE 1394. The interface includes a parallel backplane physical layer controller having multiple receive data lines for receiving data from the backplane bus, and multiple transmit data lines for transmitting data to the backplane bus. A link layer controller is coupled to the parallel backplane physical layer controller, and communicates with the parallel backplane physical layer controller over a data bus. The parallel backplane physical layer controller can provide an effective data bandwidth which is greater than its operating clock rate.
