摘要： A location of contact with a touch sensitive device is determined. Values associated with each electrode of a plurality of electrodes formed on a single layer of the touch sensitive device are sampled. A determination is made as to whether a contact with the touch sensitive device has occurred. Values sampled subsequent to the contact are adjusted based on selected stored sampled values. A location of contact is then determined based on the adjusted values.

摘要： A location of contact with a touch sensitive device is determined. Output signals associated with a plurality of electrodes such as formed on a single layer of the touch sensitive device are measured to identify a first electrode positioned at an approximate location of contact with the touch sensor. An output signal associated with a different electrode that is separated from the first electrode is measured to determine an undesired signal amount, such as due to deflection. An undesired single amount associated with the first electrode may be estimated based on the undesired signal amount measured at the other electrode. The signal amount measured at the first electrode is then compensated by the estimated undesired signal amount. The location of contact with the touch sensor is then determined based on the compensated signal amount.

摘要翻译：确定与触敏装置接触的位置。测量与多个电极相关联的输出信号，例如形成在触敏装置的单层上，以识别位于与触摸传感器接触的大致位置的第一电极。测量与从第一电极分离的不同电极相关联的输出信号，以确定不期望的信号量，例如由于偏转。可以基于在另一个电极处测量的不期望的信号量来估计与第一电极相关联的不期望的单个量。然后，通过估计的不需要的信号量补偿在第一电极处测量的信号量。然后基于补偿的信号量来确定与触摸传感器的接触位置。
