Introduction

David Sheppard is a notable inventor based in Tramore, Ireland. He has made significant contributions to the field of contact lens manufacturing, holding 2 patents that showcase his innovative approaches to production line control and tracking systems.

Latest Patents

One of his latest patents is titled "Production line control using shift registers for contact lens manufacture." This method involves controlling a production line that simultaneously processes at least two lots of contact lenses. The production line is divided into a series of cells, and a control system is implemented using at least three shift registers. These registers contain crucial information about each cell, including whether it is empty or occupied, manufacturing data, and the condition of the product. This innovative approach allows for efficient indexing of the shift registers as lenses move through the production line.

Another significant patent by Sheppard is focused on "Contact lens manufacture." This method tracks multiple SKUs of contact lenses in a manufacturing line. The process includes molding lenses, providing carriers with indicators, inspecting each lens for prescription information, and storing this data in machine-accessible memory. This systematic approach enhances the efficiency and accuracy of contact lens production.
