  • Patent number: 6876367
    Abstract: A method or a processor for filtering process for attenuation to a frequency component in a designated frequency band of a frequency of variation of a dynamic image by detecting the moving object; and subjecting at least a part of the moving object to a modified filtering process with at least a reduced attenuation or without attenuation and also subjecting a remaining part of the moving object to a normal filtering process with a non-reduced attenuation which is larger in magnitude than the reduced attenuation.
    Type: Grant
    Filed: November 30, 2001
    Date of Patent: April 5, 2005
    Assignee: NEC Corporation

  • Patent number: 6463423
    Abstract: A multi-winners feedforward neural network which is constituted while using neuron-elements consisting of the modified neural network, enables learning to be carried out autonomously regarding any problems, and is capable of being constituted by small number of LSI circuit simply. In the neural network which has a hierarchical structure consisting of one layer and/or a plurality of layers constituted by plural pieces of neurons, there is provided a controller for controlling the number of firing of the neurons, in which the number of firing of the neurons is more than two, in such a way that the number of firing of the neurons is restrained depending on a specified value and/or range of the specified value in every layer, thus preventing dissipation of the number of the neurons.

  • Patent number: 5075736
    Abstract: A superconducting three terminal device is fabricated on a substrate, and comprises first and second output signal electrodes formed of a superconductor and provided on the major surface of the substrate at a spacing, the first and second output signal electrodes having respective side surfaces, and a base electrode formed of a superconductor and provided on the first and second output signal electrodes so that ultra-small tunnel junctions takes place between the base electrode and the first and second output signal electrodes, the base electrode having a side surface, in which the first and second output signal electrodes and the base electrode are grown in first, second and third directions respectively coincident with directions of thicknesses thereof and in which the side surfaces of the first and second output signal electrodes and the base electrode are substantially perpendicular to the first, second and third directions, respectively, wherein the side surfaces of the first and second output signal ele
