Abstract

Patente de Invenção: <B>"SISTEMAS DIGITALIZADORES DE QUADRO DE APRESENTAçãO"<D>. O sistema digitalizador de quadro de apresentação para quadros de grande tamanho emprega, pelo menos, três conjuntos receptores de ultra-som afastados entre si. A posição atual do transmissor é determinada como centróide ponderado das medições da posição do tempo de duração, com base em, pelo menos, dois pares de conjuntos receptores. A ponderação usada varia em função da posição do transmissor através do quadro. Uma estrutura preferida de conjunto receptor de ultra-som para uso no sistema emprega um par de receptores de ultra-som colocados lado a lado em uma linha perpendicular à superfície do quadro de apresentação. Os receptores são conectados de modo a gerar um sinal de saída total correspondente à soma instantânea dos sinais de ultra-som recebidos em cada um deles, de modo que o conjunto receptor torna-se mais sensível aos sinais de ultra-som incidentes a partir de um plano adjacente ao quadro de apresentação. Acham-se também descritos um dispositivo transmissor para uso com caneta convencional, onde o transmissor de ultra-som é um elemento cilíndrico disposto coaxialmente com a caneta e adjacente à sua ponta, e uma estrutura apagadora articulada.
