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.

Abstract: In a method of determining noise templates for use in capacitive sensing, a plurality of changes of capacitance are acquired, which include noise components, from a plurality of sensor electrodes in a sample capacitive sensor. Each of a plurality of substantially orthogonal noise templates is determined based on the acquired plurality of changes in capacitance. Multiple substantially orthogonal noise templates are selected, from the plurality of substantially orthogonal noise templates, to be used as a set of substantially orthogonal noise templates for reduction of the noise components of the acquired plurality of changes of capacitance.
