Latest Patents

One of his latest inventions is the V-profile grinding wheel, designed specifically for V-profiling ophthalmic lenses of various diameters, powers, and thicknesses. This grinding wheel features a V-shaped groove that defines a forward V surface and a rear V surface, which meet at the nadir of the groove. The design includes a rear flat surface that tapers outwardly in relation to the wheel's axis of rotation, enhancing its grinding capabilities. The forward V surface offers a first level of grinding aggressiveness, while the rear V surface provides a greater second level, and the rear flat surface offers a third level of aggressiveness, significantly surpassing the second. Additionally, the wheel may include a forward flat surface that also tapers outwardly, providing further grinding efficiency.

Another significant patent is the lens projecting device, which is intended for use with a lens blocking device. This device features an LCD target display plane and a tower with an eyepiece. The lens projector includes a bracket fixed to the tower, with a light source positioned above the work surface. A viewer mounted in the eyepiece is aligned to project an image of a multi-focal segment or lens marking onto the graphic display. The design incorporates a shield to protect the tower from heat generated by the light source, ensuring safe and efficient operation.
