Patent number: 9335565Abstract: A light attenuating optical arrangement for assembly to an eye-shielding device includes an optical element having an electronically controlled guest-host liquid crystal cell for variably attenuating transmission of light, the liquid crystal cell including first and second plastic substrates. A controller is electrically connected to the liquid crystal cell and is configured to selectively supply a voltage across the liquid crystal cell. The controller is provided with a means for electrically connecting the controller to a power source, and a means for attaching the controller to the eye-shielding device. The optical element is provided with a means for attaching an outer periphery of the optical element to a surface of a viewing lens of an eye-shielding device.Type: GrantFiled: February 1, 2010Date of Patent: May 10, 2016Assignee: ALPHAMICRON INCORPORATEDInventors: Roy E. Miller, IV, Bahman Taheri, Tamas Kosa, Jonathan Figler, Damien Burt, Christine Martincic, Eui-Yeul Park

Patent number: 9134551Abstract: We describe a wide band variable transmission optical device, mixtures for use in such a device, and methods of making the same. The wide band optical device includes a cell comprising a guest-host mixture of a liquid crystal host and a dichroic guest dye material contained between a pair of plastic substrates. The optical device does not use polarizers. The liquid crystal host has an axis orientation that is alterable between a clear state orientation and a dark state orientation perpendicular thereto and the dichroic guest dye material includes one or more dichroic dyes. The optical device is characterized in that it exhibits a wide absorption band that is greater than 175 nm within a visible wavelength range of 400-700 nm and has a clear state transmission equal to or above 30% and a dark state transmission equal to or below 40%.Type: GrantFiled: October 4, 2011Date of Patent: September 15, 2015Assignee: ALPHAMICRON INCORPORATEDInventors: Ludmila Sukhomlinova, Volodymyr Bodnar, Christine Martincic, Linli Su, Bahman Taheri, Tamas Kosa

Patent number: 9130097Abstract: A solar powered variable light attenuating device includes a liquid crystal cell, a photovoltaic cell in electrical communication with the liquid crystal cell, and a light concentrator having a light absorbing surface and a light emitting surface optically coupled to the photovoltaic cell. At least a portion of light impinging on the light absorbing surface of the light concentrator is concentrated and directed through the light emitting surface to a photon-absorbing portion of the photovoltaic cell to generate a voltage. The generated voltage is used to change the liquid crystal cell from a de-energized state to an energized state in response to sunlight directed toward the photovoltaic cell.Type: GrantFiled: April 26, 2010Date of Patent: September 8, 2015Assignee: ALPHAMICRON INCORPORATEDInventors: Bahman Taheri, Tamas Kosa, Christine Martincic, Volodymyr Bodnar

Patent number: 8562130Abstract: An optical device with at least one interconnection tab is provided. The optical device includes a pair of opposed substrates with a gap therebetween filled with an electro-optic material. Each substrate has a facing surface with a substrate electrode disposed thereon. A sealing material is disposed between the pair of opposed substrates to contain the electro-optic material. At least one interconnection tab is interposed between the substrates. The interconnection tab includes an insulator layer with opposed surfaces. A tab electrode is provided on each surface, wherein each tab electrode is in electrical connection with a corresponding substrate electrode facing the tab electrode. And a pad electrode is also provided on each surface, wherein each pad electrode is in electronic connection with the substrate electrode facing the opposed surface of the insulator layer.Type: GrantFiled: May 2, 2011Date of Patent: October 22, 2013Assignee: Alphamicron IncorporatedInventors: Tamas Kosa, Roy Miller, Christine Martincic, Eui-Yeul Park, Bahman Taheri
