Latest Patents
One of Ashburn's notable patents is the Nutation Motion Generator. This device employs a spherical, four-bar linkage mechanism to achieve its functionality. The design features three four-bar linkage mechanisms arranged at 120-degree intervals, which are sandwiched between a stationary support surface and a drive plate. Each mechanism consists of four hinged planar sections that are triangular in shape, allowing them to converge at a central point. A universal joint at the center provides stability, enabling the device to collapse and open at various angles. The actuator, driven by controlled electric pulses, utilizes piezoceramic stacks for micro applications. This innovative design results in a compact device with improved amplification and significant gear reduction.
