Abstract

sistemas e métodos para coletar dados de sinal da retina e processo para remover artefatos. a presente invenção refere-se a um método e um sistema para a geração de dados de sinal da retina. dados de calibração correspondentes a um indivíduo podem ser recebidos. uma impedância limiar pode ser determinada com base nos dados de calibração. podem ser recebidos os dados do sinal da retina correspondentes ao indivíduo. a impedância do circuito que coleta os dados do sinal da retina pode ser comparada com a impedância limiar para determinar se os dados do sinal da retina contêm quaisquer artefatos. uma parte dos dados do sinal da retina, correspondente aos artefatos, pode ser removida dos dados do sinal da retina.
