Granted: 1982-12-09
Abstract: This specification describes an error correction system for a high density memory made up of a number of monolithic wafers each containing a plurality of arrays that are addressed thru circuitry and wiring contained on that wafer. The storage bits on the wafers are functionally divided into a number of blocks each containing a plurality of words. The words of each block are on several wafers with each word made up of a plurality of arrays on a single array wafer. Each word in a block is protected by a similar error correction double multiple error detection code. The block is further protected by two additional check words made up using a b-adjacent code. Each byte in the check words protects one byte position of the words of the block. When a single error is detected in any word by the SEC-MED code the code corrects the error. If a multiple error is detected, the multiple error signal points to the word in error to be corrected by the b-adjacent code check words.

Granted: 1985-02-28
Abstract: Zur Kennzeichnung der Werkstoffeigenschaften eines Prüf objekts werden die elektrische Leitfähigkeit und die magnetische Permeabilität herangezogen, die mittels einer Wirbelstromprüfung aus der gemessenen Impedanz einer Prüfspule ermittelt werden. Es wird eine absolute und voneinander unabhängige Bestimmung der Leitfähigkeit und der Permeabilität auch bei hochpermeablen Werkstoffen ohne Eichnormale angestrebt. Hierzu wird bei einer niedrigen Prüffrequenz von z.B.    5 kHz die Permeabilität des Werkstoffs durch Vormagnetisieren reduziert und dabei die Leitfähigkeit bestimmt, während die Permeabilität bei einer höheren Frequenz von z.B. 1 MHz ohne Vormagnetisieren ermittelt wird. Dabei ergeben sich Leitfähigkeit und Permeabilität durch Vergleich der gemessenen Impedanzwerte der Abtastspule mit gespeicherten Werten, deren Zuordnung zu den Leitfähigkeit-Permeabilität-Paaren aus numerischen Berechnungen oder aus Messungen an Proben mit definierten elektrischen und magnetischen Eigenschaften bekannt ist.
