1. A stylus, comprising:
- a grip switch configured to exhibit a change in an electrical resistance in response to an applied force input, the grip switch comprising;
a spacer formed from a compressible material;
a first electrode positioned external to the spacer and having an internal surface associated with the spacer; and
a second electrode positioned external to the spacer and having an internal surface associated with the spacer, wherein the second electrode is spaced apart from the first electrode to define a gap between the first electrode and the second electrode, and wherein compression of the spacer under the applied force input moves one or more of the first electrode or the second electrode to narrow a width of the gap and provide an electrical connection between the first electrode and the second electrode;
a grip switch module coupled to the grip switch and configured to provide a first signal in response to the change in the electrical resistance between the first electrode and the second electrode of the grip switch;
a processor coupled to the grip switch and the grip switch module and configured to transition from a first state to a second state in response to the first signal, wherein the processor is configured to provide information indicative of one or more of a position or a movement of the stylus during operation in the second state, and wherein the processor is further configured to consume less electrical energy in the first state than in the second state; and
a transmitter configured to communicate the information to an external device using electronic signals, wherein the transmitter transitions between an inactive state and an active state in response to a second signal provided by the processor.

Abstract
An activation signal is provided in response to a user gripping force incident to a grip switch. Electronic circuitry transitions from an inactive state to an active state in response to the activation signal. The activation signal may also include encoded information regarding user identity, gripping force magnitude, user input gesturing, and the like. The electronic circuitry may use the information encoded in the signal to select or perform particular functions or operations. Power consumption of a stylus, user device, or other apparatus is reduced, or various functions are improved, accordingly.
