  • Ruggedized active stylus with a single mechanism to enable access to two separate chambers
    Patent number: 10908708
    Abstract: In some examples, an active stylus may include a main portion and a top portion. The main portion may include a dry chamber used to store a battery. The top portion may include a wet chamber to store spare nibs. The wet chamber may be accessed to replace a damaged nib with a spare nib. When the top portion is fully mated with the main portion of the stylus, turning the top portion, in a first direction, relative to the main portion until the detent is reached and pulling the top portion from the main portion enables access to the wet chamber. Turning the top portion of the active stylus, in the first direction, relative to the main portion past the detent, until the top portion detaches from the main portion, enables access to the dry chamber.
