Abstract
A processing system for an input device includes a sensor module coupled to sensor circuitry and configured to receive signals from an active pen. The processing system for an input device further includes a determination module configured to: determine, based on a signal exceeding a power threshold, that the signal is boosted, transition, in response to the signal being boosted, from a first state to a contact state, receive a contact packet from the active pen, and determine an attribute of the active pen using the contact packet.
