Patent number: 11547523Abstract: An instrument holder assembly for use with a robotic surgical system can comprise one or more modules for holding or guiding an instrument. Each module can comprise a variable diameter jaw having movable teeth configured to hold or guide different sized instruments. Each module can be attached to opposite ends of a main shaft that can couple to an arm of the robotic surgical system. A central passage can extend through each module and the main shaft and the variable diameter jaws can constrict the central passage. Teeth of the variable diameter jaws can be biased to a closed or opened position. A tensioner tool can be used to hold biasing elements in position so that the teeth can be loaded into the module. The teeth can be loaded into slots of the module using a tooth holder device.Type: GrantFiled: July 8, 2020Date of Patent: January 10, 2023Assignee: MedTech S.A.Inventors: Eric Roussel, Andrei Basturescu

Patent number: 9352510Abstract: The invention relates to a method for adjusting the position of a transparent element (1), consisting in forming an image of a peripheral edge (B1) of the transparent element, using the light diffused by said peripheral edge. In this way, movements by the transparent element relative to reference marks can be followed on a screen or carried out automatically based on an analysis of the image. The method can be used to apply a piece of film (2) to a spectacle lens, adjusting the distance between the respective peripheral edges (B1, B2) of the spectacle lens and the piece of film.Type: GrantFiled: September 22, 2010Date of Patent: May 31, 2016Assignee: Essilor InternationalInventor: Eric Roussel

Patent number: 8641853Abstract: A method of transferring a portion of a functional film (1) onto a substrate from a base plate (100) comprises the formation of a groove (S1) which passes through the said functional film and also a separating film (2) placed between the functional film and the base plate. A portion (2p) of the separating film is then detached from the base plate with the portion of the functional film. The portion of said separating film protects the portion of the functional film in the rest of the method. According to one improvement, the portion of the functional film which is detached from the base plate comprises a useful portion (1p) and a margin (1m) that are connected together by the portion (2p) of the separating film. The useful portion (1p) of the functional film may then be gripped and handled via the margin (1m).Type: GrantFiled: July 13, 2009Date of Patent: February 4, 2014Assignee: Essilor International (compagnie Generale d'optiqueInventors: Daniel Darmes, Nicolas Lavillonnière, Christelle Marck, Eric Roussel
