    Abstract: A portable electronic device may include a battery assembly and a battery swell detection unit in proximity to the battery assembly. The battery swell detection unit may include an electrode, a dome made of an electrically conductive material positioned between the battery assembly and the electrode, a processor, and memory having programmed instructions that cause the processor, when executed, to detect battery swelling based on a depression of the dome.

    Abstract: A system and method for enabling a stylus to be used with a touch sensor even after it has failed in an open mode or a closed mode, wherein the tethered stylus activates the inking function when the stylus is in contact with the touch sensor and deactivates the inking function when the stylus is lifted off the surface of the touch sensor when the switch is functioning properly, but when there is a failure of the switch in the open mode or the closed mode, enabling the tethered stylus to continue functioning by using a timer to activate the inking function when the tethered stylus is close enough to be detected by a touch sensor, and to deactivate the inking function when the tethered stylus is no longer detectable by the touch sensor.

    Abstract: A system and method for enabling noise avoidance between multiple capacitive touch sensing circuits operating in a same device and which may interfere with each other, wherein a master controller is coupled to all of the capacitive touch sensing circuits to prevent them from using measurement frequencies and from jumping to new measurement frequencies that may interfere with each other, thereby allowing the capacitive touch sensing circuits to function properly.
