Abstract

Patente de Invenção: <B>''DISPOSITIVO DE MARCAçãO PARA QUADRO DE APRESENTAçãO ELETRôNICO''<D>. é descrito um dispositivo de transmissor para uso com uma caneta convencional, no qual o transmissor de ultra-som é um elemento cilíndrico que permanece coaxial com a caneta adjacente à sua ponta, e uma estrutura de apagador articulada.Técnicas de triangulação convencionais são usadas para trilhar a posição e o movimento de um dispositivo de escrita ou dispositivo de apagamento. Uma facilidade de codificação associada com a caneta apresenta a habilidade de distinguir se a acaneta é usada para marcar ou como um implemento de apagamento, bem como para determinar a natureza ou o caráter da largura da linha escrita ou faixa do apagador. Um fluxo de dados assim gerado pode ser usado em uma variedade de maneiras, tal como, por exemplo, para alimentar informação na memória de um computador digital, e/ou para alimentar informações para a transmissão para estações remotas.
