摘要： In one embodiment, a method includes modifying an amount of charge of a capacitance of a touch sensor. The modified amount of charge resulting in a voltage at the capacitance being a first pre-determined voltage level. The method also includes applying a first pre-determined amount of charge to the capacitance. The application of the first pre-determined amount of charge to the capacitance modifying the voltage at the capacitance from the first pre-determined voltage level to a first charging voltage level. The method also includes determining a first difference between the first charging voltage level and a reference voltage level; and determining whether a touch input to the touch sensor has occurred based on the first difference.

摘要： In certain embodiments, a touch sensitive device includes a cover panel, a plurality of drive electrodes positioned below the cover panel, a plurality of sense electrodes positioned below the cover panel, and a controller. The controller includes a signal generator operable to supply a drive signal to a particular drive electrode of the plurality of drive electrodes. The controller further includes measurement circuits associated with each of the plurality of sense electrodes, each measurement circuit being operable to generate a signal corresponding to the charge transfer between the particular drive electrode and a corresponding sense electrode. The drive signal supplied by the signal generator has a frequency that reduces the charge transfer caused by a fluid layer located on the cover panel to an amount falling below a threshold corresponding to the point at which the controller determines that a touch is present.

摘要： A system includes a controller situated on a circuit board and a touch sensor coupled to the controller. The touch sensor includes a plurality of electrodes configured to capacitively coupled to a surface. The system also includes a drive element that is coupled to the controller. The controller is configured to send a drive signal to the drive element and, after sending the drive signal to the drive element, receive a set of sense signals from the touch sensor. The controller is further configured to determine whether an object that is not contact with the surface is in a vicinity of the surface the set of sense signals.
