Patent ID: 8350821

Claim:
A method for establishing no-event baseline sensor output values for sensors in an event sensor panel without corruption by touch or hover events on or about the sensor panel, comprising: during boot-up of a sensor panel subsystem, performing a scan of the sensor panel to obtain new sensor output values, computing offsets for use in generating normalized baseline sensor output values, generating the normalized baseline sensor output values, computing a first value as a function of one or more new sensor output values above the normalized baseline sensor output values, computing a second value as a function of one or more new sensor output values below the normalized baseline sensor output values, determining whether the second value is greater than the first value by a predetermined margin, re-scanning the sensor panel if it is determined that the second value is not greater than the first value by the predetermined margin, and recapturing the normalized baseline sensor output values if it is determined that the second value is greater than the first value by the predetermined margin.
