Patent number: 8446657Abstract: Embodiments relate to a method and apparatus for producing polarized light, having a modulator crystal, where the modulator crystal incorporates a birefringent electro-optic material. The modulator crystal has an optic axis, a first polarization axis, and a second polarization axis, where the first polarization axis and second polarization axis are each perpendicular to the optic axis and perpendicular to each other. The apparatus can also include an electrode pair, where application of an electric field modulates light passing through the modulator crystal that is polarized along the first polarization axis. Embodiments pertain to a method and apparatus for modulating light. The apparatus incorporates a modulator crystal having an electro-optic material. The device also has at least two electrode pairs, where each electrode pair modulates light passing through the modulator crystal that has a direction of travel that has a component parallel to the optic axis.Type: GrantFiled: August 21, 2012Date of Patent: May 21, 2013Assignee: University of Florida Research Foundation, Inc.Inventors: Volker M. Quetschke, Wan Wu, Luke Williams, Muzammil A. Arain, Rodica Martin, David Reitze, David B. Tanner, Guido Mueller

Patent number: 6699142Abstract: A golf putter head comprises a main head body, a striking surface and a rear part. A cavity is formed at a central part of the rear part, and two protrusions are formed at both ends of the rear face. A base of the cavity is designed into a thin shaped structure. A center of gravity of the putter head is shifted behind the striking surface and the weight of the putter head is shifted to both its ends.Type: GrantFiled: January 28, 2003Date of Patent: March 2, 2004Assignee: Fine Earth Enterprise Ltd.Inventor: Wan Wu
