Latest Patents

One of his latest patents is the Piezoelectric Multiplexer. This invention includes an actuator and multiple piezo-morph beams. The actuator consists of an actuator conducting head and an actuator stem, while each piezo-morph beam features a conducting beam contact head and a beam stem made from piezo-morph material. A control voltage is selectively applied to electrical contacts linked to the beam stems, creating a piezoelectric effect that bends the chosen piezo-morph beam, establishing an electrical connection between its contact head and the actuator's conducting head. A control circuit with a controller signals which piezo-morph beam to connect to the actuator. This multi-piezo-morph-beam piezoelectric multiplexer can be affixed to the electrical terminals of various electrical components, such as transistors, to create an electrical cell that can be manufactured on a semiconductor chip or within a microelectromechanical system (MEMS) device.

Another significant patent is the Driver Circuit and Method for Single-Phase and Three-Phase Induction Motors. This control circuit for an induction motor determines whether the motor is of the three-phase or single-phase type. If it is three-phase, a variable frequency drive operation is implemented. If it is single-phase, a closed-loop current control process is executed. This process includes measuring winding resistances and determining a turns ratio for the main and auxiliary motor windings. The turns ratio is utilized in the closed-loop current control process to scale a measurement of current in the auxiliary winding, generating the control voltage for the auxiliary winding. The phase of the current in the windings is further processed to create a phase control signal.
