Patent number: 9869887Abstract: A structural interface having an adaptive liquid crystal material that is positioned to receive electromagnetic radiation and adapted to reflect a selective band of the received electromagnetic radiation so as to help with cooling of a structure in the summer and/or heating of the structure in the winter. The adaptive liquid crystal material is designed to change its selective reflection band when exposed to an activating temperature or an activating light or both. Depending on the interior and/or exterior conditions, the adaptive liquid crystal material has one or more selective reflection bands with a peak wavelength selected from the following: within a sunlight wavelength span, outside a thermal infrared wavelength span, outside the sunlight wavelength span, or within the thermal infrared wavelength span. The structural interface may be applied to an exterior or interior surface of a structural envelop or be integrated into a structural envelope material.Type: GrantFiled: November 30, 2012Date of Patent: January 16, 2018Assignee: ALPHAMICRON INCORPORATEDInventors: Bahman Taheri, Ludmila Sukhomlinova, Paul Luchette

Patent number: 9303209Abstract: A light emitting photonic bandgap (PBG) material, and devices uses the same, having (a) a polymer network exhibiting a non-uniform pitch; (b) a small molecule liquid crystal material with a birefringence>0.04; and (c) one or more light emitting dyes having a low triplet state absorption. The light emitting PBG material has a defect-induced density of states enhancing feature at a wavelength that overlaps the emission spectrum of the light emitting dye. Excitation of the light emitting PBG material by a light source causes a directional electromagnetic emission from the light emitting material. The PBG material, and device, are capable of emitting continuous wave laser light as a result of excitation by a low-power incoherent light source.Type: GrantFiled: July 11, 2013Date of Patent: April 5, 2016Assignee: ALPHAMICRON INCORPORATEDInventors: Antonio Munoz, Tamas Kosa, Paul Luchette, Ludmila Sukhomlinova, Bahman Taheri

Patent number: 9116370Abstract: Provided is a liquid crystal light variable device having a liquid crystal cell, comprising a mixture of a liquid crystal material and one or more dichroic dyes interposed between a first and a second substrate, each substrate having a conductive layer disposed thereon. The device further includes a voltage supply or controller coupled with the conductive layers for application of a voltage waveform across the liquid crystal cell. The liquid crystal cell is configured so that based on the voltage waveform applied, the device transitions between a low-haze low-tint state (“clear state”), a low-haze high-tint state (“tinted state”), and a high-haze high-tint state (“opaque state”). The high-haze state is caused by dynamic scattering in the liquid crystal-dye mixture.Type: GrantFiled: May 7, 2013Date of Patent: August 25, 2015Assignee: ALPHAMICRON INCORPORATEDInventors: Bahman Taheri, David Baker, Elliott Bardun, Tamas Kosa, Ludmila Sukhomlinova, Paul Luchette

Patent number: 8169680Abstract: Polymers that undergo a reversible phase change in response to being exposed to a light from a laser having a radiation pressure greater than a threshold level. The phase changeable polymers have the ability to reduce the intensity of the laser and can advantageously scatter laser light incident on the polymers. The on-off response of such polymers is in the microsecond range and the light scattering property is independent of laser wavelength. The polymers can beneficially be incorporated into devices to protect human vision and optical instruments that are vulnerable to lasers at high intensities. Methods for making and using such devices are also disclosed.Type: GrantFiled: September 19, 2007Date of Patent: May 1, 2012Assignees: Kent State University, The Texas A&M University SystemInventors: Hanbin Mao, Paul Luchette, David E.
