    Abstract: Member functions of certain disjoint sets of harmonically related trigonometric product functions (the term ''''disjoint'''' is used herein to describe sets which have no common member functions and relatively distinct class properties K) are combined for transmission by simultaneously selecting plural subsets of a first one of the sets, in fundamental half-periods, and superposing the members of each subset by linear addition to form subset composites. These are individually multiplied (''''upconverted'''') by members of other sets and superposed in groups. Such cascaded multiplications and superpositions are continued convergently to provide at one central terminal a comprehensive high order composite transmission waveform which has smooth outline and contains, in a highly distinguishable form, all of the binary intelligence utilized in the initial selections of subsets of the first set. At receiving apparatus the composite transmission waveform is decomposed (down-converted) in divergently cascaded stages of multiplications by locally synthesized functions. Plural sets of higher order product waveforms, issuing from the last stages of such multiplication in parallel, are separately integrated over fundamental half-period intervals. The integrand functions correspond to distinct sums of products of pairs of high order trigonometric product functions having identical class and order. The terms of any sum all have distinct binary coefficients. The product functions form an orthogonal set with associated order and class properties respectively relating to sums and maxima of respective order and class properties of the disjoint sets containing the transmission components. Each integrand sum representation contains a unique term in which the paired product functions are identical and all other terms have unmatched functions. The function in the matching term is different for each integrand. Hence with appropriate timing of integration sampling and resetting functions a unique set of binary state pulse functions, which correspond to the binary coefficients of the matching terms of respective integrands, is sampled at outputs of respective integration stages. Normally these pulse functions correspond identically to the binary selection pulses utilized in the pretransmission subset selections.

    Abstract: A colour graphics display having a read/write control system for a buffer memory therein provides Line-on-Line and Underpaint mode operation, if selected and enabled, by reading the contents of a frame buffer storage location for which new pixel data is being provided, comparing those contents with data representing a display background characteristic or colour, and if the result of the comparison is positive, storing the new pixel data to the frame buffer storage location. If the result of the comparison is negative, a selected data value different from the new pixel data is stored to the frame buffer storage location.

    Abstract: Ein System und Verfahren zum Verwalten einer Transaktionsverarbeitung werden offenbart. Das Verfahren eines oder mehrere aus einem Empfangen einer von einer Client-Einheit übertragenen Nachricht, wobei die Nachricht ein vordefiniertes strukturelles Format zum Verarbeiten durch ein dienstbereitstellendes Datenverarbeitungssystem enthält, einem Ermitteln eines Typs der Nachricht und einem Erkennen eines oder mehrerer sensibler Felder innerhalb der Nachricht auf Grundlage des ermittelten Typs der Nachricht, einem Anonymisieren von Werten des einen oder der mehreren sensiblen Felder innerhalb der Nachricht, während das vordefinierte strukturelle Format intakt bleibt, sowie einem Übertragen der anonymisierten Nachricht, die den einen oder die mehreren anonymisierten Werte enthält, wobei das strukturelle Format intakt bleibt, an das dienstbereitstellende Datenverarbeitungssystem. Das System kann Daten aus einem privaten Netzwerk anonymisieren, bevor sie an einen öffentlichen Dienst übertragen werden.
