Patent EP-0135290-A2 (EP)
Inventor: BUCKLEN WILLARD KRAIG
IPC: H03M1/00
Filed: 1984-07-16
Abstract: A parallel analog-to-digital converter employing a novel binary encoding technique to reduce the errors arising from multiple one-to-zero transitions in comparator outputs. An analog signal to be converted is applied in conventional fashion to an array of comparators, from which are obtained an array of output signals having a transition from ones to zeros at the array position corresponding to the analog signal magnitude. The one-to-zero transition is detected by conventional AND gate circuitry and the resulting one-in-(2"-1) code is transmitted to encoding logic configured to produce a novel form of binary output code. The code is identical to Gray code in all but its least significant bit position, which alternates between one and zero values in the manner of standard binary code. The new code results in a significant reduction in the magnitude of errors arising from multiple transitions between one and zero in the array of comparator outputs.

Abstract: An apparatus for recognising unknown input patterns is described. The pattern to be recognised is converted into electrical signals representing, for example, the darkness or density of the picture elements forming the input pattern by units 1, 2, 4 and 4. The signals are stored in an input pattern memory 4. A basis generating unit 5 generates a plurality of orthonormalised vectors or bases from the stored input pattern, these are used to construct an input subspace of the input pattern. A reference pattern memory 8 stores reference patterns for a number of categories. These reference patterns vectors which are used to construct a reference subspace. A similarity value is defined as an angle 8 between the input subspace and the reference subspace. A matrix generating unit 7 and an eigenvalue calculating unit 10 are provided for measuring the angle e. The matrix generating unit 7 produces a matrix from the orthonormalised vectors generated by the basis generating unit 5 and the reference patterns stored in the reference memory 8. The maximum eigenvalue of the matrix calculated by eigenvalue calculating unit 10, corresponds to the angle 8. A decision unit 12 determines the category to which the input pattern belongs by comparing the eigenvalues representing the categories.
