    Abstract: Using a capacitance sensor may include taking a first noise measurement by imposing a first signal on a capacitance sensor, the first signal having a first frequency; taking a second noise measurement by imposing a second signal on the capacitance sensor, the second signal having a second frequency different than the first frequency; determining the measurement with the lower amount of noise between the first noise measurement and the second noise measurement; and taking a capacitance measurement by imposing a third signal on the capacitance sensor, the third signal having either the first frequency or the second frequency based, at least in part, on the frequency of the measurement with the lower amount of noise.

    Abstract: A portable electronic device may include an electrical resistance sensor and a battery assembly being adjacent to the electrical resistance sensor. The electrical resistance sensor is positioned to be compressed when the battery assembly swells, and the electrical resistance sensor further includes a pressure sensitive material that exhibits a characteristic of changing an electrical conductance when compressed.

    Abstract: A computing device may include a keyboard, a switch in mechanical communication with an underside of a key arranged in the keyboard, a processor, a transmit line electrically connected to the processor, a sense line electrically connected to the processor, and the transmit line and the sense line are selectively connectable through the switch when the key is depressed, memory in communication with the processor, and programmed instructions stored in the memory that, when executed, cause the processor to identify changes in capacitance from the sense line when the key is not depressed, identify a hand gesture performed proximate the keyboard based on the changes in capacitance, and execute an action based on at least one the identification of the hand gesture.

    Abstract: Systems and methods for providing a touch sensor include a dynamic suspension system to enable the touch sensor to emulate the tactile sensation that a user feels when using pushbutton switches, wherein a touch sensor is combined with at least one snap dome and a post inside the snap dome to keep the touch sensor rigid until the touch sensor is allowed to be displaced when a force is applied, and then the post is retracted or released to enable movement of the touch sensor and the snap dome are disclosed. Also disclosed are systems and methods for a clickable touchpad that enables the clickable function to be selectively locked or unlocked in accordance with detected or sensed conditions are disclosed.

    Abstract: Adjusting a cursor speed may include a sensor with at least one capacitance sense electrode, a controller in communication with the sensor, memory in communication with the controller, and programmed instructions stored in the memory and configured, when executed, to cause the capacitance controller to detect movement of an object moving proximate the sensor at an object speed, apply a cursor speed to a cursor depicted in a display based at least in part on a cursor-to-object speed relationship, detect a trigger event in the detected object movement, and change the cursor-to-object speed relationship in response to detecting the trigger event.
