Patent abstract
A touch input device configured to detect stylus signals generated by an external stylus is provided. The touch input device includes a plurality of stylus signal detectors that can receive the stylus signal and estimate the start and end time of the stylus signal in order to facilitate windowed demodulation of signal. The touch input device also includes circuitry to determine which of the plurality of detectors is most likely to have received the stylus signal and based on that determination can demodulate the signal and extract data embedded within the stylus signal.
