Abstract: A touch sensor can be used with a finger and/or a pen configured to provide a touch input to the touch sensor. Some implementations involve touch capacitive touch sensing, although many implementations are also applicable to other touch and pen technologies, such as resistive, surface acoustic wave, bending wave, touch force, electromagnetic (E-M).

Abstract: A touch-sensitive apparatus includes a touch panel comprising a touch sensitive surface and at least one a drive electrode capacitively coupled to at least one receive electrode. A sense circuit generates a response signal for the receive electrode in response to a drive signal delivered to the drive electrode. A measurement circuit applies a time-varying transfer function to the response signal. The transfer function varies proportionately and synchronously with the response signal. A calibration circuit is used to match the time-varying transfer function to the response signal.

Abstract: Touch location determination approaches involving a plurality of touch location techniques are described. Each touch location technique is capable of independently determining a location of a touch within a touch area of the touch sensitive device. The touch location determination made by at least one touch location technique is enhanced using touch location information associated with the touch acquired from one or more other touch location techniques. One touch location technique may use a different type of sensor, signal, and/or algorithm from the one or more other touch location techniques.
