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.
Claims27
A method to acquire sensor data from a touch-surface, the touch-surface being used for user-input in an electronic device that provides radio frequency (“RF”) communications capability, comprising:
- acquiring first data from a first set of sensors associated with the touch-surface;
- initiating acquisition of second data from a second set of sensors associated with the touch-surface if a RF pulse is not currently being generated by the electronic device, and, if a RF pulse is currently being generated by the electronic device, initiating acquisition of the second data from the second set of sensors after the RF pulse has terminated.
An electronic device for providing radio frequency (“RF”) communication capability, comprising:
- a touch-surface having a plurality of sets of sensors;
- a RF generation circuit for generating RF pulses;
- a RF detection circuit for detecting when a RF pulse is being generating by the RF generation circuit;
- a sense circuit, operatively coupled to sensors in the touch-surface sensor array, for acquiring data from the sensors in the touch-surface sensor array;
- and
- a control circuit that initiates acquisition of first data from a first set of sensors associated with the touch-surface, initiates, if a RF pulse is not currently being generated by the electronic device, acquisition of second data from a second set of sensors associated with the touch-surface, and initiates, if a RF pulse is currently being generated by the electronic device, acquisition of the second data from the second set of sensors after the RF pulse has terminated.
