Abstract

Data acquisition from a touch-surface input unit may be disrupted during the generation of radio frequency ('RF') pulses. To mitigate this problem, touch-surface data acquisition is temporarily halted during RF pulse generation. Data collected prior to temporarily halting is retained, with subsequently acquired data being added to prior collected data.
