Claim:
1. A method comprising: receiving, by a stylus, a first signal wirelessly from a device, the stylus being operable to wirelessly transmit signals to and receive signals from the device; filtering, by the stylus, the first signal received by the stylus from the device to attenuate noise, the filtering of the first signal resulting in a filtered first signal; determining, by the stylus, a characteristic of the filtered first signal; receiving, by the stylus from the device, data regarding a known characteristic of the first signal; comparing the determined characteristic of the filtered first signal with a first threshold and a second threshold, wherein the first threshold is for determining whether to process signals wirelessly received by the stylus from the device and the second threshold is for determining whether to adjust the first threshold; and dynamically adjusting, by the stylus and based at least in part on the determined characteristic of the filtered first signal received by the stylus from the device, whether the determined characteristic of the filtered first signal meets the second threshold, and the known characteristic of the first signal, the first threshold for determining whether to process signals wirelessly received by the stylus from the device and the second threshold, the first threshold dynamically adjusted between a maximum value and a minimum value.
