Title: Innovations of Elizabeth A Lillis
Introduction
Elizabeth A Lillis is a notable inventor based in Athlunkard, Ireland. She has made significant contributions to the field of electrical engineering, particularly in the areas of capacitance measurement and fan speed control. With a total of 3 patents to her name, Lillis has demonstrated her expertise and innovative spirit.
Latest Patents
One of her latest patents focuses on capacitance measurement. This invention provides a method for measuring an unknown capacitance of a device. The method involves driving a test signal to a circuit system that includes a current divider formed by the device with unknown capacitance and a reference capacitor. It mirrors a current developed in the reference capacitor to a second circuit system that includes a measurement impedance. The voltage within the second circuit system is measured, and the unknown capacitance is derived based on the measured voltage with reference to the capacitance of the reference capacitor and the measurement impedance.
Another significant patent by Lillis pertains to fan speed control. This invention describes a method of synchronizing a pulsed drive signal applied to a DC fan motor to the TACH output of the motor. The method defines an ideal TACH output for a specific rotation speed of the rotor of the DC fan. It changes the period of the drive signal if the monitored TACH output does not match the ideal TACH output, ensuring that the period of the drive signal matches the time taken for the fan to rotate through one magnetic pole of the fan.
