Abstract
A detector for use in a transcription system comprising: a signal receiver for positioning adjacent a writing surface and for receiving a position signal transmitted from a stylus when the stylus is positioned adjacent the writing surface, the signal receiver producing a timing signal in response to receiving the position signal; and a signal focussing element having a reflecting surface which is shaped and oriented relative to the signal receiver to reflect the position signal transmitted from the stylus onto the signal receiver.

A detector for use in a transcription system comprising:
- a signal receiver for positioning over a writing surface and for receiving a position signal transmitted from a stylus when the stylus is positioned over the writing surface, the signal receiver producing a timing signal in response to receiving the position signal;
- and
- a signal focussing element having a reflecting surface which is shaped and oriented relative to the signal receiver to reflect the position signal transmitted from the stylus onto the signal receiver.
A detector for use in a transcription system comprising:
- a signal receiver for positioning over a writing surface and for receiving an ultrasound position signal transmitted from a stylus when the stylus is positioned over the writing surface, the signal receiver producing a timing signal in response to receiving the ultrasound position signal;
- a signal focussing element having a stationary reflecting surface which is oriented relative to the signal receiver to reflect the ultrasound position signal transmitted from the stylus onto the signal receiver;
- and
- a signal shielding element shaped and oriented relative to the signal receiver to reflect ultrasound position signals transmitted by the stylus away from the signal receiver when the stylus is positioned outside a predetermined region of the writing surface.
