Abstract: A system and method for capacitive sensing comprise acquiring first capacitive sensor data and second capacitive sensor data from a plurality of sensor electrodes, and determining positional information from one or more input objects based on the first capacitive sensor data and the second capacitive sensor data. The plurality of sensor electrodes are driven with transcapacitive sensing signals for capacitive sensing during one or more transcapacitive sensing blocks to acquire the first sensor data. Further, the plurality of sensor electrodes are operated for absolute capacitive sensing during one or more absolute capacitive sensing blocks to acquire the second capacitive sensor data.

Abstract: A method and related processing system and input device are disclosed for power consumption optimization using interference measurements. The method comprises applying, within a predefined first low-power operational mode, a first set of values for at least one predefined sensing parameter and corresponding to a first power consumption level; acquiring, within the first low-power operational mode, a first interference measurement using the plurality of sensor electrodes; transitioning, upon determining the first interference measurement exceeds a first interference threshold value, into a predefined high-power operational mode; and applying, within the high-power operational mode, a second set of values for the at least one predefined sensing parameter and corresponding to a second power consumption level greater than the first power consumption level.
