Patent number: 8899762Abstract: An exterior sideview mirror system includes an exterior sideview mirror assembly including a reflective element having a rearward field of view when attached to a side of an automobile. The reflective element includes has a plano reflective element and a separate auxiliary reflective element having a curvature. The plano reflective element and the auxiliary reflective element are supported adjacently at a backing plate element having a first support portion supporting the plano reflective element and a second support portion supporting the auxiliary reflective element. The auxiliary reflective element is positioned at an outboard portion of the reflective element assembly when the exterior sideview mirror assembly is attached to the side of the automobile. When the exterior sideview mirror assembly is attached to and operated at the side of the automobile, the field of view of the auxiliary reflective element overlaps with the field of view of the plano reflective element.Type: GrantFiled: July 21, 2014Date of Patent: December 2, 2014Assignee: Donnelly CorporationInventor: Niall R.

Publication number: 20140346156Abstract: An adaptive mirror for a laser processing apparatus has a housing and a pressure chamber which is arranged in the housing and can be connected to a pressure source. A mirror substrate, which delimits the pressure chamber, is fixedly clamped in the housing. Depending on the internal pressure in the pressure chamber, which can be changed by means of the pressure source, the mirror substrate is deformed. The mirror substrate has a stiffness which increases towards the geometric centre at least in a region surrounding the geometric centre of the mirror substrate. By means of such a stiffness distribution, an almost spherical deformation can be achieved over a large surface of the mirror substrate despite the mirror substrate's being fixedly clamped into the housing.Type: ApplicationFiled: May 20, 2014Publication date: November 27, 2014Applicant: LT-Ultra Precision Technology GmbHInventor: Dietmar Bischof

Patent number: 8894226Abstract: A method for producing a multiple surface system that may be a two-mirror surface. The method involves first finding from a given primary curve an appropriate secondary curve. The method then uses ideas from exterior differential systems to grow from the primary curve and the secondary curve, primary and secondary mirror surfaces. The Cartan-Kähler theorem gives a strong indication of the existence of such solution surfaces.Type: GrantFiled: April 14, 2011Date of Patent: November 25, 2014Assignees: Drexel University, The Trustees of The University of PennsylvaniaInventors: Robert Andrew Hicks, Christopher Croke

Publication number: 20140268380Abstract: A light weight minor comprising a reflecting element adapted to receive shape adjustments or corrections from an actuated frame. Shape adjustments may be as simple as a uniform curvature, although saddle or higher order shapes are also possible. The frame may execute such adjustments by varying tension or by torsion, with variations applied either locally or uniformly. The frame may be configured to contact a membrane reflector either from one or both sides. Thermal and piezoelectric examples of actuation means are provided along with methods of controlling the shape of said mirrors. To suppress the occurrence of possible vibrations, said mirrors are also provided with eddy current vibration damping means.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Inventor: Andrei Szilagyi

Patent number: RE45511Abstract: A deformable optical device includes a reflection device having a first reflecting surface and a second surface, an actuator (e.g., an integrated circuit piezoelectric actuator) having a support device and moveable extensions extending therefrom, which are coupled to the second surface, and electrodes coupled to corresponding ones of the extensions. Wavefront aberrations are detected and used to generate a control signal. The extensions are moved based on the control signal. The movement deforms the reflecting surface to correct the aberrations in the wavefront.Type: GrantFiled: April 21, 2010Date of Patent: May 12, 2015Assignee: ASML Holding N.V.Inventors: Pradeep K.
