Patent number: 10254447Abstract: A system and method of generating machine marking instructions for marking an ophthalmic lens is disclosed. The method comprises the steps of receiving lens order data related to a lens order, receiving an initial marking layout and calculating, using the lens order data, ophthalmic lens data of an ophthalmic lens related to the lens order. The method also comprises the steps of determining, using the ophthalmic lens data, marking parameters relating to the ophthalmic lens, producing an additional marking layout by modifying the initial marking layout using the marking parameters and the lens order data, the additional marking layout representing the markings to be applied to the ophthalmic lens, and generating machine marking instructions arranged to cause a marking machine to mark the ophthalmic lens in accordance with the additional marking layout.Type: GrantFiled: December 14, 2012Date of Patent: April 9, 2019Assignee: ESSILOR INTERNATIONALInventors: Florence Legrand, Robert Pellegris, Vincent Roblot, Laurent Marcepoil, Sebastien Maurice, Frederic Dubois

Patent number: 10189220Abstract: A calculation system (1) for manufacturing an ophthalmic lens. A set of calculation modules (M1, M2, M3, M4) is associated to partial calculation in relation with manufacturing process of said ophthalmic lens. A managing unit (MU) is configured to: receive input data, and calculate output data through one or several iteration(s) of: determining one or several calculation module(s) to be activated, determining an order of activation of the one or several calculation module(s), and activating the determined one or several calculation module(s), in accordance with the determined order of activation. The managing unit transmits an indication that the output data have been calculated.Type: GrantFiled: April 16, 2014Date of Patent: January 29, 2019Assignee: Essilor InternationalInventors: Laurent Marcepoil, Sebastien Maurice, Luc Martin, Benoît Holvoet Vermaut
