Latest Patents

One of his latest patents is a voltage-based braking methodology for a power tool. This invention allows for braking a power tool motor based on the phase voltage of the motor. The design includes a motor and a power source that provides operating power to the motor. A power switching network is positioned between the power source and the motor to drive the motor. An actuator is operable to provide an input, while an electronic controller is connected to both the actuator and the power switching network. The electronic controller is designed to receive an indication related to initiating braking of the motor, control the power switching network to allow the motor to coast, monitor the phase voltage of the motor, and determine whether the phase voltage is equal to or less than a specified threshold. In response to this condition, the controller manages the power switching network to brake the motor.

Another notable patent is for an impact power tool. This tool features a housing that supports a motor, along with a spindle that receives torque from the motor to facilitate rotation. The design incorporates a reciprocating impact mechanism that creates a variable pressure air spring within the spindle. This mechanism includes a striker that reciprocates along a designated axis in response to the air spring, and a piston that also reciprocates to induce the air spring. The crankshaft converts continuous rotational motion from the motor into reciprocating linear movement of the piston, ensuring that the center of gravity of the tool is optimally positioned.
