Abstract: A method and tool to smooth surface contours uses a fixed back plate mounted at a known distance to an actuator holding plate. Each of the actuators is mounted in said actuation holding plate by a support collar threaded into said actuator holding plate. Threaded with said support collar is an actuator holder with rigidly holds an actuator. A differential threaded adjustment device is then inserted through said fixed back plate and connected to say support collar and actuator holder so that each can be moved independently of the other. The actuator is made of two piezoelectric plates connected in parallel and seperated by a silicon rubber o-ring.

Abstract: A device and method for controlling a population of burrowing rodents including a remote control panel having a welding torch. The welding torch includes a gas flow valve. A pair of hoses are connected between the welding torch, a bottle of oxygen and a bottle of fuel gas. Another hose having a length greater than 5 feet is connected to a downstream end of the gas flow valve and extends and connects to an injector. An ignition wire extends between an ignition switch and the injector. The hose connecting the welding torch and the injector may be twenty-five feet long. In operation, an operator places a fire cone end of the injector in a hole connected to a tunnel system and then steps back to the remote control panel positioned at a location remote to the fire cone to operate gas flow and ignition of gas in the tunnel.

Abstract: A system for supplying optical power uses an optical switch or shutter at the handpiece. The optical switch is positioned between an open light-transmitting position and a closed light-reflecting position. A detector at the base of the system can be used to detect the position of the optical shutter in some situations. This can be used to control the operation of a high-intensity light source. In this manner, the system can be controlled at the handpiece without using electrical power at the handpiece.
