Abstract

Patente de Invenção:<B>"MéTODO DE MANIPULAçãO DE COLISõES EM UM SISTEMA PARA O INTERCâMBIO DE DADOS SEM CONTATO"<D>. O método manipula colisões em um sistema de intercâmbio de dados entre objetos portáteis ou "distintivos" e pelo menos um terminal transceptor de dados adequado para a operação em conjunto com uma pluraridade de distintivos simultaneamente presentes no campo de ação do terminal. O método compreende as seguintes etapas sucessivas: a) o terminal transmite, à dita pluraridade de distintivos, mensagens de chamada geral, cada uma incluindo um parâmetro de modulação de probabilidade de colisão; b) cada distintivo condicionalmente transmite, ao terminal, uma mensagem de resposta de chamada geral com uma probabilidade de menos do que 100% como uma função do parâmetro de modulação de probabilidade de colisão, cada mensagem de resposta de chamada geral contendo um identificador específico com relação ao distintivo; c) na recepção por partícula do terminal de uma mensagem de resposta de chamada geral, e na ausência de qualquer colisão entre a dita mensagem e uma mensagem transmitida por um outro distintivo, um enlace de comunicação de dados específico se estabelece entre o terminal e o distintivo, e o intercâmbio de dados continua, retornando para a etapa a) para uma nova iteração; e d) de outra forma, o método retorna para a etapa a) para uma nova iteração, opcionalmente modificando a faixa dinâmica do parâmetro de modulação de probabilidade.
