Abstract:
1. A method comprising: receiving at a stylus a receive signal from a device, the stylus comprising one or more computer-readable non-transitory storage media embodying logic, the device comprising a touch sensor, the receive signal being received at the stylus through the touch sensor of the device and one or more electrodes of the stylus; determining whether a level of the receive signal substantially meets or exceeds a first pre-determined threshold; if the level of the receive signal substantially meets or exceeds the first pre-determined threshold, then transmitting the receive signal to the logic for processing; if the level of the receive signal does not substantially meet or exceed the first pre-determined threshold, then filtering out the receive signal from processing by the logic; comparing the level of the receive signal to a second pre-determined threshold; based at least in part on the comparison, dynamically adjusting the first pre-determined threshold; receiving at the stylus a second receive signal from the device; and determining whether a level of the second receive signal substantially meets or exceeds the dynamically adjusted first pre-determined threshold.
