Latest Patents

One of his latest patents is titled "Resistance welding with minimized weld expulsion." This invention involves a system designed to form a weld nugget in a metal workpiece. The system includes a power supply, actuator, electrodes, and a controller. The actuator delivers a variable electrode force to the workpiece based on a force command. The controller executes a method by transmitting a welding current command to the power supply, which outputs a welding current to the electrodes. The controller also transmits the force command to the actuator to apply the variable electrode force at a first force level. This force increases from a second force level immediately after a specified duration to minimize weld expulsion. The second force level begins at a point in time in the dynamic resistance profile where the dynamic resistance value of the workpiece decreases at a threshold rate during the formation of the weld nugget.

Another significant patent is "Torque-customized shredder load calibration." This invention focuses on paper shredder thickness calibration using a Hall effect torque detector connected to a paper shredder motor. The system produces a signal corresponding to the motor's rotation. A controller receives this signal and determines the motor torque, which corresponds to the shreddant thickness. The signal is compared to a predetermined maximum signal, beyond which an overload is indicated. This method enhances the operation of a paper shredder by ensuring optimal performance based on the shreddant thickness.
