1. A method for establishing no-event baseline sensor output values for sensors in a multi-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 number of new sensor output values above the normalized baseline sensor output values,computing a second number of new sensor output values below the normalized baseline sensor output values,determining whether the second number is greater than the first number by a predetermined margin,re-scanning the sensor panel if it is determined that the second number is not greater than the first number by the predetermined margin, andrecapturing the normalized baseline sensor output values if it is determined that the second number is greater than the first number by the predetermined margin.
