Patent number: 10575725Abstract: Described herein is a light directing assembly for use in an object analysis system. The light directing assembly includes a plurality of optical relay assemblies. Each optical relay assembly includes at least one optical element configured to relay an interrogation beam from a light transmission system to an object and relay a return beam from the object to the light transmission system, the return beam being generated by reflection or back scattering of the interrogation beam by the object. Each optical relay assembly defines an interrogation angle at which the interrogation beam relayed by the optical relay assembly reaches the object, and an optical path length being the distance from the light transmission system to the object travelled by an interrogation beam via the optical relay assembly.Type: GrantFiled: February 28, 2018Date of Patent: March 3, 2020Assignee: Brien Holden Vision Institute LimitedInventors: Klaus Ehrmann, Darrin Mark Falk, Cathleen Fedtke

Patent number: 7810925Abstract: A contact lens having near vision and distance vision portions, the lens being movable on the eye between first and second positions, those positions corresponding with aligning the wearer's vision through the near vision and distance vision portions respectively. The lens is positionally stable on the eye in each of the two positions, and requires a force to be applied to the lens to move between the first and second positions. Preferably the lens has a back surface and a front surface, and said back surface has either one or two major back curve zones occupying a major portion of the lens back surface.Type: GrantFiled: April 30, 2009Date of Patent: October 12, 2010Inventors: Simon Rodney Evans, Arthur Ho, Geoffrey Peter Brent, Klaus Ehrmann, Darrin Mark Falk, Sandya Indrani Perera, Jacqueline Tan, Renee Du Toit
