  • Patent number: 5691676
    Abstract: Strip line filter, receiver with strip line filter and method of tuning the strip line filter. In ceramic filters for frequencies from 1 to 2 GHz, strip line resonators lying in one plane and coupled via the side are currently used in the state of the art. For reducing the attenuating effect of such a filter in the passband, the strip line resonators are arranged in two different planes and coupled via the broad side.

  • Patent number: 5630020
    Abstract: The invention relates to a method of learning which is carried out in a neural network operating on the basis of the gradient back-propagation algorithm. In order to determine the new synaptic coefficients with a minimum learning period, the invention introduces parameters which privilege corrections based on the sign of the error at the start of learning and which gradually induce less coarse corrections. This can be complemented by other parameters which favor a layer-wise strategy, accelerating the learning in the input layers with respect to the output layers. It is also possible to add a strategy which acts on the entire neural network.
