Patent number: 10401537Abstract: A fluidic lens may include an optical surface configured for deflection dominated by bending stress. An adjustable concentric load may be applied to the optical surface to cause a clear aperture region of the optical surface to deflect with generally spherical curvature. Adjusting the concentric load controls the radius of curvature. An adjustable uniformly-distributed load may be applied to the optical surface by fluid pressure that causes the clear aperture region to deflect with an aspheric shape. Adjusting the pressure controls the asphericity of curvature. First and second fluids having similar densities and different refractive indexes may be disposed on either side of a deflectable optical surface to help balance gravitational loading on either side of the optical surface, thereby reducing gravity-associated aberrations.Type: GrantFiled: November 22, 2016Date of Patent: September 3, 2019Assignee: HOLOCHIP CORPORATIONInventors: Robert G. Batchko, Andrei Szilagyi, Samuel T. Robinson

Patent number: 10073199Abstract: A fluidic lens may have a reservoir at least partially bounded by a first optical surface and a second optical surface. A fluid fills a volume of the reservoir. A piston is configured to contact a portion of the first or second optical surface from outside the reservoir. One or more of the first optical surface or second optical surface is configured to deform as a result of a change in a pressure applied to the fluid or a change in contact between the piston and the first or second optical surface. A rim is configured to contact a portion of the first or second optical surface from outside the reservoir. One or more of the first optical surface or second optical surface is configured to deform as a result of a change in a pressure applied to the fluid or a change in contact between the rim and the first or second optical surface.Type: GrantFiled: September 13, 2016Date of Patent: September 11, 2018Assignee: HOLOCHIP CORPORATIONInventors: Robert G.

Patent number: 10027255Abstract: Apparatus, and a corresponding method for its operation, for precisely moving a movable rotor by urging a motor, such as a piezoelectric motor, into operative engagement with a circumferential rim-like portion of the rotor, with a radial preload force great enough to produce tangential motion in the rim-like portion and thereby to move the rotor in any desired manner and with very high precision. Possible damaging effects of the radial preload force are canceled by the introduction of an oppositely directed radial resistive force, such as by means of one or more pinch rollers positioned opposite the motor and also engaging the rim-like member. The motor is mounted in an assembly that permits limited sliding and pivoting movements of the motor and thereby allows the motor to adapt to any physical irregularities in the driven rim-like member.Type: GrantFiled: March 14, 2014Date of Patent: July 17, 2018Assignee: MICROCOSM, INC.Inventor: Andrei Szilagyi

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.
