摘要： Systems and methods for estimating an efficiency of a catalyst placed in an exhaust path of a combustion engine are disclosed. In one example approach, a method comprises: ageing the catalyst consecutively at different temperatures for definite time periods; measuring the catalyst conversion efficiency after each ageing step; calculating the ageing factor for each step of the ageing procedure and the accumulative value of the ageing factors for all steps of the ageing procedure; estimating catalyst efficiency correlation factors related to the measured catalyst conversion efficiency for each temperature point and for all ageing conditions; determining a correlation between the catalyst efficiency correlation factors and the accumulative value of the ageing factors; and calculating the conversion efficiency of the aged catalyst based on a predetermined correlation between the accumulative ageing factor and the catalyst efficiency correlation factor.

摘要： A semiconductor device package comprises a container including a base and sidewalls. The base is configured to support a semiconductor device chip, and a lead frame extends through at least one of the sidewalls. A portion of the lead frame within the sidewall has at least one aperture penetrating into the lead frame. The sidewall material extends into the aperture, thereby forming a strong interfacial bond that provides a low leakage, sidewall-lead-frame interface. The base has a reentrant feature that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby forming a low leakage base-sidewall interface. The top surface of the base has a groove that is positioned within the thickness of at least one of the sidewalls and engages the at least one sidewall, thereby enhancing the low leakage base-sidewall interface.

摘要： A diesel exhaust treatment system and method of oxidizing NO to NO2 at low temperatures are provided. The system utilizes a platinum catalyst on a zirconia-stabilized silica support which oxidizes NO in the exhaust gas to NO2 and uses the NO2 in an amount sufficient to oxidize particulate trapped on a particulate filter. The catalyst is preferably pre-treated at a temperature of between about 500 to 650° C. in a NO-oxygen-nitrogen mixture to increase conversion at low temperatures. The catalyst preferably includes an additional oxide component selected from the group consisting of TiO2, P2O5, WO3, B2O3, and Al2O3. or a heteropolyacid component to further increase activity at low temperatures or to decrease platinum loading at the same level of performance.

摘要： Electrical devices having tunable electrical characteristics are provided, such as variable resistors, capacitors and inductors. The tunable electrical characteristics are achieved by placing an appropriate material between substrate layers and by controllably applying a pressure to the material to compress the material or alter the shape of a well in which the material is contained, and thereby alter the electrical characteristics of the electrical device. The composition, shape and dimension of the embedded materials determine how the electrical characteristics of the electrical device are altered upon compression of the embedded material in response to an applied control signal. Generally, as the embedded material is compressed, the material will become more dense and the electrical characteristics of the integrated electrical device is altered.

摘要： A diesel engine equipped with an exhaust gas particulate filter includes a control system that reduces exhaust gas smoke emissions normally resulting from an extended period of engine idling. The control method periodically raises the exhaust gas temperature in order to purge the particulate filter of water and hydrocarbons that build up during extended engine idling and cause exhaust smoke. A timer records the elapsed period during which the engine remains at idle and the exhaust temperature is below a threshold level. When the recorded time period exceeds a preselected value, the filter is purged by elevating the exhaust gas temperature to a level sufficient to oxidize the gaseous hydrocarbons and evaporate any water that may have accumulated in the filter.
