Abstract (en)
[origin: GB2337330A] A transcription system is provided which includes a plurality of signal, eg ultrasonic, receivers 12A, 12B for positioning adjacent a writing surface 28 and for receiving a position signal transmitted from a stylus 10 when the stylus is positioned adjacent the writing surface, the signal receivers producing timing signals in response to receiving the position signal from the stylus, the transcription system using the timing signals to determine a position of the stylus adjacent the writing surface. The receivers are each provided with a parabolic element (Figs 7A - 7C) which has a reflecting surface to reflect and forms the position signal transmitted by the stylus onto the receiver. A signal shielding element may also be provided to reflect position signals transmitted from the stylus away from the receiver when the stylus is positioned outside a predetermined region of the writing surface. The receivers may be coupled by a member capable of adopting two or more configurations in which the distances between the two receivers are different.
