Publication number: 20070274695Abstract: Latch control methods and systems are disclosed, including a latch that receives power from a motor associated with an H-bridge circuit. A sensor can be provided for monitoring the latch, wherein the sensor obtains latch feedback data from the latch. A microcontroller controls the latch based on the latch feedback data, by controlling an interaction of the H-bridge circuit and the motor with the latch. Additionally, a microprocessor processes instructions for controlling the interaction of the H-bridge circuit and the motor with the latch. Such instructions can be implemented as Proportional Integral Derivative (PID) control instructions.Type: ApplicationFiled: May 26, 2006Publication date: November 29, 2007Inventor: John Phillip Chevalier
