Abstract

INALADOR COM SENSOR DE FLUXO DIRECIONAL. é descrito um sensor de fluido para ativar e controlar vários componentes de um dispositivo para inalação. O sensor de fluido inclui um elemento acústico, tal como um microfone, posicionado no interior do dispositivo de inalação, para detectar fluido no interior do dispositvo e emitir sinais representativos da freqüência, direção e/ou amplitude do fluido. Tais sinais controlam e ativam uma placa eletrostática e/ou um vibrador de alta freqüência.
