  • Patent number: 8170822
    Abstract: A compensation method devoid of operating voltage calibration, establishing fundamental linearity calibration table and inputting, and detecting the actual operating voltage is disclosed. The compensation method comprises the steps of: a) turning off a switch in a touch sensor system; b) initializing the touch sensor system and measuring a reference frequency outputted from a oscillator in the touch sensor system; c) turning on the switch and measuring a first frequency outputted from the oscillator; and d) deducting the first frequency from the reference frequency so as to obtain a frequency difference; and e) comparing the difference with a predetermined value, and judging based upon the difference if the touch sensor system is touched by a foreign object.

  • Patent number: 7714673
    Abstract: The present invention relates to a control method for the operation modes of an oscillator and the apparatus thereof, for which the method and the apparatus can be applied to the electronic circuits with multi-operation modes of the oscillator so as to correctly choose the desirable oscillator operation mode. Furthermore, an oscillator checking circuit sets up the oscillation mode automatically and judges if the oscillator operates properly. Hence, there is no need for the user to set up the oscillator operation mode manually.
