摘要： In a method of interference avoidance for a capacitive sensor device, a transmitter signal is transmitted with a transmitter electrode of the capacitive sensor device. A resulting signal is received with a receiver electrode of the capacitive sensor device. The resulting signal corresponds to the transmitter signal. A first demodulated output is acquired by demodulating the resulting signal in a first way. A second demodulated output is acquired by demodulating the resulting signal in a second way, where the second way and the first way differ. A shift is made from using the first demodulated output for determining positional information to using the second demodulated output for determining positional information. The shift is based at least in part upon an amount of interference.

摘要： The various embodiments described herein provide input devices configured to selectively operate in two different sensing regimes. The first sensing regime is configured to determine positional information for ungloved fingers in the sensing region. The second sensing regime is configured to determine positional information for gloved fingers in the sensing region. The input devices are further configured to switch from operating in the first sensing regime to the second sensing regime responsive to detecting an input gesture that meets each of a set of criteria, where the set of criteria includes a measure of sensor value stability corresponding to the input gesture being beyond a sensor value stability threshold level. So implemented, the input device allows a user to easily switch between two different sensing regimes, and thus can facilitate the use of the device with both gloved and ungloved fingers providing input.

摘要： A processing system for a capacitive input device comprises sensor circuitry and control logic. The sensor circuitry is configured to be communicatively coupled with sensor electrodes of the capacitive input device. The control logic is configured to operate the capacitive input device in a first mode comprising interference sensing at a first level and input object sensing. The control logic is also configured to operate the capacitive input device in a second mode instead of in the first mode in response to: interference measured in the first mode meeting an interference condition; and a determination that input is in a sensing region of the capacitive input device. While operating in the second mode, interference sensing with the capacitive input device is either not performed or else is performed at a second level that is lower in fidelity than the first level.

摘要： Devices and methods are provided that utilize a first electrode disposed on a first substrate and a second electrode disposed on a second substrate, where the first electrode and the second electrode define at least part of a variable capacitance. A third substrate is arranged between the first substrate and the second substrate, the third substrate having an opening arranged such that at least a portion of the first electrode and the second electrode overlap the opening. A transmission element is provided that partially overlaps the opening. The transmission element is physically coupled to the second electrode such that a force biasing the transmission element causes the second electrode to deflect relative to the first electrode, thus changing the variable capacitance. A measurement of the variable capacitance may then be used to determine force information.
