Abstract
Abstract A pointer position detection system for use in determining the position of a pointer relative to a tablet comprising a signal generating system coupled to the tablet for transmitting a driving signal, a movable pointer responsive to the transmitted driving signal, the pointer including a signal processor responsive to the driving signal for processing information contained in the driving signal and for generating a processed signal indicative thereof, the pointer further including a storage circuit for storing energy from the driving signal, the storage circuit being coupled to the signal processor, the pointer further including a transmitter system coupled to the signal processor for transmitting the processed signal, the transmitter system being adapted to transmit the processed signal using the stored energy in the storage circuit from the driving signal, and a signal detector for detecting the transmitted processed signal. The use of the stored energy is particularly useful when the signal generator is not transmitting the driving signal. In a particular embodiment, the storage circuit for storing energy from the driving signal is a capacitor and the transmitter system includes a pair of field effect transistors.
