|20140306926||METHOD OF DETECTING PRESENCE OF INTERFERENCE SOURCE, AND TOUCH SENSING SYSTEM - A method for detecting presence of an interference source is to be performed by a touch sensing system that stores a threshold capacitance difference. The method includes the steps of sampling capacitances periodically within a time period for obtaining a base capacitance value; sensing a comparison capacitance after the time period; computing an absolute difference between the comparison capacitance and the base capacitance value; and determining that the interference source is present when the comparison capacitance is smaller than the base capacitance value and the absolute difference is greater than the threshold capacitance difference.||10-16-2014|
