Abstract |
AB |
[DE] Es wird eine extrem flache analoge Drucktaste und Tastatur beschrieben. Hierzu werden flache, folienförmige und druckabhängige Widerstände eingesetzt.
[EN] The keyboard incorporates one or more flexible foil, pressure-responsive electrical resistances, converting directly applied finger pressure into a corresponding analogue electrical signal which can then be converted into a digital signal. Two or more foil resistances may be positioned directly after one another for providing input signal redundancy. |
