  • Apparatus and method for controlling a device
    Patent number: 10333443
    Abstract: An apparatus and method for adjusting an amplitude of a drive signal applied to a device are presented. The method of driving a device includes providing a drive signal to drive the device, monitoring a gradient value of the response signal; and changing an amplitude level of the drive signal based on the gradient value. The monitoring of the gradient value includes sensing an electrical parameter of the response signal and calculating the gradient value based on the electrical parameter.
    Type: Grant
