Latest Patents
One of his latest patents is the "Anti-lock brake system permanent magnet motor having differential." This invention features an electric motor-driven brake pressure modulator that utilizes two auxiliary field windings. These windings are designed to produce varying speed and torque performance characteristics based on the direction of motor rotation. In forward rotation, the auxiliary field windings enhance the magnetic field, maximizing torque for adequate brake pressure. Conversely, in reverse rotation, they reduce the magnetic field to quickly decrease brake pressure.
Another significant patent is the "Power window control with tape drive tension release." This motor control apparatus is designed for vehicle power window mechanisms. It includes a flexible drive element that drives the window in a predetermined direction. The system automatically relieves tension by reversing the motor direction briefly when the window reaches the desired position. This reverse operation is precisely controlled to prevent unwanted movement of the window.
