His work primarily focuses on enhancing the efficiency and safety of waterjet systems.

Latest Patents

One of Andrew's latest patents is a method of using a contour follower. This contour follower includes a plurality of sensors strategically placed around a waterjet nozzle. Each sensor is designed to measure the distance between a working surface and a first plane that is perpendicular to the nozzle's longitudinal axis. The sensors may consist of hall-effect sensors positioned in the first plane, with magnets located in a second plane parallel to the working surface. A detecting circuit processes signals from these sensors to determine the angle of the working surface relative to the first plane, as well as the distance between the nozzle's aperture and the working surface. Additionally, a collision detection sensor provides a signal if the device approaches within a selected distance of an obstruction on the working surface. To enhance safety, a shield plate is incorporated to block and dampen secondary spray-back of cutting fluid occurring at low angles above the working surface.

Another patent focuses on a collision detection sensor for a waterjet system. This sensor signals when the device approaches an obstruction within a specified distance on the working surface. An annular pressure switch, lying in a first plane, provides this signal when radial pressure is applied to its perimeter via an annular trigger skirt. The trigger skirt applies radial pressure in response to a collision with an obstacle, ensuring the safety and reliability of the waterjet system.
