摘要： A method for noise reduction in a digitizer includes determining a location of a stylus with a known frequency of emission over a first sampling period, sampling output from a plurality of detecting elements over a second sampling period, identifying detecting elements with sampled output in the second sampling period above a defined threshold in a selected frequency, the selected frequency being close to but different than the known frequency of the stylus, selecting as a candidate carrier of mere noise a detecting element from the detecting elements identified that is spaced away from the determined location of the stylus, and reducing values of output sampled over the second sampling period from at least one other detecting element, in accordance with the output sampled over the second sampling period from the detecting element selected as the candidate carrier of mere noise.

摘要： A method for classifying input provided to a digitizer sensor includes sampling output over one or more sampling periods, identifying a location of intentional input to the digitizer sensor from the output sampled over the one or more sampling periods, identifying an area of potential palm input based on the identified location of the intentional input, and classifying output detected in the area of the potential palm input as output potentially obtained from undesired input to the digitizer sensor. The area of potential palm input is defined to have a defined spatial relation to the location of the intentional input. The output classified is sampled over one or more sampling periods other than the one or more sampling periods from which the area of potential palm input is identified.
