Patent number: 10471546Abstract: A laser system is configured to produce a distribution of self-focus damage volumes through the thickness of a substrate. A laser of the laser system produces a laser beam, and an optical assembly receives the laser beam and emits a conditioned laser beam having a geometric focal region. Placing the substrate in the path of the conditioned beam shifts the focal region to an effective focal region. The optical assembly and/or optical elements thereof can be configured such that the distribution of self-focus damage volumes is uniform over the thickness of the substrate by accounting for the non-linear effects of the substrate on the light that propagates through the substrate.Type: GrantFiled: December 22, 2014Date of Patent: November 12, 2019Assignee: GENTEX CORPORATIONInventors: Kurtis L. Geerlings, Donald L. Bareman, Henry A. Luten, Niels A. Olesen, David J. Cammenga

Patent number: 10427606Abstract: Anisotropic film laminates for use in image-preserving reflectors such as rearview automotive mirror assemblies, and related methods of fabrication. A film may comprise an anisotropic layer such as a light-polarizing layer and other functional layers. The film having controlled water content is heated under omnidirectional pressure and vacuum to a temperature substantially equal to or above a lower limit of a glass-transition temperature range of the film so as to be laminated to a substrate. The laminate is configured as part of a mirror structure so as to increase contrast of light produced by a light source positioned behind the mirror structure and transmitted through the mirror structure towards a viewer. The mirror structure is devoid of any extended distortion and is characterized by SW and LW values less than 3, more preferably less than 2, and most preferably less than 1.Type: GrantFiled: December 28, 2015Date of Patent: October 1, 2019Assignee: GENTEX CORPORATIONInventors: John S. Anderson, William L. Tonar, Henry A. Luten, George A. Neuman, Gary J. Dozeman, Tammy G. Morgan, David J. Cammenga

Publication number: 20190258130Abstract: A method for removing a material from a surface of a substrate includes impinging a laser beam on the material during a first sweep to remove the material from the surface along a first line and impinging the laser beam on the material during a second sweep to remove the material from the surface along a second line adjacent to the first line. The first line includes first artifacts that form a first portion of an array of artifacts on the surface. The second line includes second artifacts that form a second portion of the array of artifacts on the surface. A first laser pulse of the laser beam corresponding with the second sweep is synchronized with a start of the second sweep when transitioning between the first line and the second line such that the start of the second sweep coincides with the first laser pulse.Type: ApplicationFiled: May 7, 2019Publication date: August 22, 2019Inventors: Henry A.

Patent number: 10345672Abstract: A vehicular rearview assembly with a mirror element having a curved or rounded edge on the first surface that is fully observable from the front of the assembly, a complex peripheral ring, and a user interface with switches and sensors that activate and configure pre-defined function(s) or device(s) of the assembly in response to the user input applied to the user interface. The mirror element is supported by a hybrid carrier co-molded of at least two materials, a portion of which is compressible between the housing shell and an edge of the mirror element. The peripheral ring may include multiple bands. Electrical communications between the electronic circuitry, the mirror element, and the user interface utilize connectors configured to exert a low contact force, onto the mirror element, limited in part by the strength of adhesive affixing the EC element to an element of the housing of the assembly.Type: GrantFiled: November 16, 2016Date of Patent: July 9, 2019Assignee: GENTEX CORPORATIONInventors: Jeffrey T. Bruizeman, Henry A. Luten, John S. Anderson, George A. Neuman

Patent number: 10131016Abstract: A laser system includes a buffer material at an entry surface of a substrate in which laser-induced channels are formed. The laser beam propagates through the buffer material and impinges the substrate with a central axis of the laser beam at an oblique angle of incidence. The buffer material has a refractive index that may be closer to that of the substrate than is the refractive index of the atmosphere, such as air, in which the laser system operates. The buffer material facilitates forming laser-induced channels at relative large angles with respect to the substrate surface by attenuating energy loss or other effects on the laser beam that are normally caused by the mismatch in refractive index between the environment and the substrate in the absence of the buffer material.Type: GrantFiled: August 14, 2015Date of Patent: November 20, 2018Assignee: GENTEX CORPORATIONInventors: Kurtis L.
