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.

Description

[0001] related application [0002] The subject matter claimed herein is related to U.S. Patent Application No. 10 / 840,862, entitled "Multipoint Touchscreen," filed May 6, 2004 by Steve Hotelling and Brian Huppi (filed March 30, 2006) ) in U.S. Patent Application 11 / 278,080 entitled "Force Imaging Input Device and System" and in U.S. Patent Application 11 / 382,402 entitled "Force and Location Sensitive Display" by Steve Hotelling (filed May 9, 2006) The above-mentioned patent applications are hereby incorporated by reference in their entirety for the subject matter described. technical field [0003] The present invention generally relates to power consumption and noise mitigation techniques for electronic devices. More particularly, but not limitedly, the present invention relates to reducing or avoiding operational problems due to power drops and electronic interference during touch surface data acquisition operations within portable electronic devices that generate radio fr...
