Abstract:
A method for immersing a substrate into a plating solution. In one embodiment, the method includes applying a first waveform to the substrate as the substrate is being immersed into the plating solution, stopping the application of the first waveform to the substrate as soon as the substrate is fully immersed inside the plating solution, and applying a second waveform to the substrate prior to the substrate being situated into a plating position.
Abstract:
A method of managing vapors generated from an ammonia-containing reductant delivery system for a vehicle is described. The method may include storing ammonia containing vapors generated in the reductant delivery system during engine-off and then purging said stored ammonia into an exhaust of the engine to react in a catalyst in the exhaust flow during engine operation.
Abstract:
A method of operating a reductant delivery and storage system of a vehicle, comprising of storing an ammonia-containing fluid in a first storage device, generating ammonia vapors in the first storage device, storing said generated ammonia vapors in a second storage device, purging said stored vapors from the second storage device to an exhaust of the engine, and relieving pressure or vacuum build-up during at least one of said storing and purging is provided via an atmospheric vent coupled in the reductant delivery and storage system.
Abstract:
Systems and methods are described for controlling an engine in a vehicle. One example method includes, after a threshold duration of engine idling, continuing engine idle operation when an exhaust NOx sensor indicates a NOx level below a NOx threshold, and stopping engine idle and shutting down the engine when the exhaust NOx sensor indicates the NOx level is above the NOx threshold.
Abstract:
A method for operating an internal combustion engine Exhaust Gas Recirculation (EGR) system that includes producing an EGR valve position signal to decrease the amount of exhaust gas passed to the EGR cooler when a processor determines the EGR cooler efficiency is less than the predetermined level and producing an EGR coolant valve position signal to decrease the amount of coolant passed to the EGR cooler when such processor determines the EGR cooler efficiency is less than the predetermined level. The processor produced EGR valve and the EGR coolant valve position signals result in regeneration within the cooler, returning the effectiveness of the cooler to a near “clean” condition.
Abstract:
Techniques for configuring a customer premises equipment connected to a network of a network service provider include receiving configuration information at a distributed component on the network from a central unit on the network. The distributed component also receives from the customer premises equipment a request for values of configuration parameters that determine network properties for the customer premises equipment. The distributed component generates a set of values for the configuration parameters based on the request and the configuration information received from the central unit. The set of values are sent from the distributed component to the customer premises equipment. A system using these techniques is scalable with increasing numbers of customer premises equipments simultaneously requesting values for configuration parameters and is robust in face of equipment failure at a distributed component or at the central unit or both.
Abstract:
In a transaction system, a dynamic batching process enables efficient flushing of data in a data buffer to a stable storage device. The transaction system uses constant values and dynamic values and a system performance history to adjust the rate of flushing data and also to adjust the amount of data flushed in each flush operation. The transaction system is able to respond to both spikes in rate of received transactions as well as more gradual changes in the rate of received transactions and to automatically adapt to stable storage device performance variations.
Abstract:
A method for establishing class of service configuration in a network device of a broadband cable network using Dynamic Host Configuration Protocol (DHCP) is disclosed. A request to obtain a network address presented using DHCP is received from a network interface unit over the cable network, generally upon boot up of the network interface unit. A DHCP message is received from a registration center, and the message includes a network address and a quality of service code value associated with the network interface unit. Based on the quality of service code value, a quality of service configuration is established in the cable network for the network interface unit. As a result, quality of service information is obtained for each network interface unit in the network, specifically when the network interface unit is activated, and as part of its boot-up sequence. Carrying the quality of service information in a DHCP message enables configuration of the network rapidly and without introducing an additional protocol.
Abstract:
A method is provided for managing vapor generation in a reductant storage and delivery system. In one example, urea vapors generated from liquid in a storage device are temporarily stored and later purged to the exhaust system of the engine.
