Abstract
Patente de Invenção: <B>"SOLUçãO ELETRôNICA PARA DESALINHAMENTO NãO-LINEAR DE SCANNERS DE SAíDA DE VARREDURA"<D>. Um circuito eletrônico é utilizado para corrigir um desalinhamento não-linear de um scanner de saída de exploração. Este circuito utiliza um gerador de clock principal para gerar um clock principal. Apenas durante o tempo em que uma linha de varredura estiver sendo varrida, a freqüência do clock principal é modulada de acordo com uma curva de correção. Entre cada duas linhas de varredura consecutivas, a freqüência do clock principal é calibrada para uma freqüência de referência. Isso permite que cada linha de varredura receba um clock principal com a mesma freqüência do começo de uma linha de varredura.Invention Patent: <B> "ELECTRONIC SOLUTION FOR NONLINEAR SCALING OF SCAN OUTPUT SCANNERS" <D>. An electronic circuit is used to correct a non-linear misalignment of a scan scanner. This circuit uses a main clock generator to generate a main clock. Only during the time that a scan line is being scanned, the frequency of the main clock is modulated according to a correction curve. Between every two consecutive scan lines, the main clock frequency is calibrated to a reference frequency. This allows each scan line to receive a main clock at the same frequency as the beginning of a scan line.
