INDUKTANZ MIT SEGMENTIERTEM KERN IN STIFT FÜR ELEKTROMAGNETISCHE TAFEL |
摘要 |
A graphical tablet and a stylus interact electromagnetically with one another. The stylus includes a coil and a transducer to affect an inductance of the coil in response to a force exerted on a tip of the stylus. The transducer comprises first and second ferrite cores. The cores are mounted to move with respect to one another in response to the force. The cores are substantially in contact with one another in the absence of the force. Disengaging causes a well detectable jump in the inductance. |
