摘要： Exhaust gas treatment is based on metal foams using catalytic coatings. A catalytic converter for diesel and gasoline engines includes oxidation catalysts, 3-way catalysts, de-NOx catalysts, NH3 slip catalysts. Foam high surface areas and high mixing rates enhance catalytic performance. Particulate filtration in both diesel and direct injection gasoline engines uses deep bed filtration. A multiple-pass radial flow uses more than one foam segments, separated by a diaphragm. Filtration, pressure drop and catalytic performance are enhanced using variable foam porosities in axial and radial flow directions and non-uniform catalyst coatings. More than one catalytic functionalities may be incorporated in a single shell. Secondary foam segments are placed within main foam segments. Diaphragms at the entrance and exit of the external shell allow the flow to be divided between the main and the secondary foam segments according to the respective flow resistances.

摘要： A filtering device for diesel engines is based on metal foams. In order to achieve high filtration efficiency with low pressure drop using deep bed filtration metal foams, a radial flow concept is used based on a “porosity gradient”. The foams can also be coated with catalytically active material to enhance soot oxidation (regeneration), as well as reduction of other exhaust gas pollutants (CO, hydrocarbons, nitrogen oxides). This may be accomplished by using non-uniform amounts of catalytic materials within the filter depending on the targeted application. An additional secondary filter segment may be placed within the metal support of the main filter segment. The metallic diaphragms at the entrance and exit of the external shell are designed in such a way as to allow the flow to be divided between the main and the secondary filter segments according to the respective flow resistances.

摘要： An integrated printed inductor has a set of open petal loops, connected together in series. For a given inductance value higher quality factor and higher frequency value result using an equal chip surface area. With the same fabrication cost and equal occupied area, higher quality factor values at higher frequency can be achieved. The innovative shape is such that secondary mutual coupling effects occur and contribute to increases of overall inductance values. Small current loops arranged as petals corresponding to inductance value LO are connected in series for the inductance value to add up to a higher value. The loops are connected along a circular path to minimize the total chip area occupied. A secondary loop in the center of the inductor results in a stronger magnetic flux and a higher inductance value, due to both self inductance of the secondary loop and mutual inductance of it with the petals.

摘要： Signals transmitting symbols through a multi-paths channel are received by a diversity receiver using at least two branches. The signals are combined after their processing in individual branches, minimizing combining loss of EGC receivers, minimizing BER and optimizing the performance. Processing in individual branches includes estimation of the phase changes induced by the channel at each received signal, with reference to the transmitted signal, and weighting of each signal by a co-phasing coefficient based on said estimation, so that all received signals are co-phased. An optimization step includes estimation of mean value and variance of signal to noise ratio (SNR) in each branch, using sampling techniques, and weighting the received signals by an optimization coefficient calculated from the mean value and variance. The process avoids expensive hardware for continuous estimation of instantaneous channel gains at each branch.
