Latest Patents

Among his latest patents is the Computer Controller Optical Surfacing (CCOS) Lap Pressure Control System. This invention discloses a rotary lapping system and process designed to produce a controlled pressure gradient, including both positive and negative lift, when lapping a workpiece coated with an abrasive slurry liquid. The system utilizes a plurality of grinding pads mounted beneath a rotating lap substrate, which are tilted at specific angles to achieve the desired hydrodynamic reaction with the abrasive slurry. Additionally, the controlled pressure gradient can be varied by decentering the rotation of the lap substrate.

Another significant patent is the Thermal Actuator Apparatus. This device is designed to control or adjust the position of a surface or other object based on temperature changes. The operation relies on the rate of change in the modulus of rigidity or elasticity of counterbalanced springs made from different materials, resulting in a shift in equilibrium position. The movement of an actuating surface, coupled to the spring system, can be utilized to change or control the position of an object in response to temperature variations.
