Publication number: 20180231861Abstract: A transparent photovoltaic (TPV) integrated directly into the structure of an electrochromic (EC) device is beneficial in that it can eliminate at least one substrate and provide more uniform coloring. Integration of a transparent photovoltaic with an electrochromic device may also reduce or eliminate the need for an electrical bus on a substrate. In some embodiments, positioning the TPV internally with the EC cell may eliminate the need for additional substrate layers or a conductive layer on one side of the TPV cell. Integrating a PV cell into the EC device can additionally reduce the need for external wiring and an external power supply. Alternatively, the TPV can assist in charging a battery where the battery can be used to power the EC device when there is no sunlight available.Type: ApplicationFiled: February 8, 2018Publication date: August 16, 2018Applicant: Gentex CorporationInventors: Sue F.

Publication number: 20180231869Abstract: The present invention belongs to the technical field of lasers, and particularly relates to a periodically poled crystal and an optical parametric amplifier. The present invention provides a periodically poled crystal, including a first nonlinear region, a linear region and a second nonlinear region, wherein the first nonlinear region and the second nonlinear region both have periodically poled structures. The optical parametric amplifier having the periodically poled crystal can separate the idler wave from the signal wave besides achieving the basic function of optical parametric amplification because the by-produced idler wave transmits in a direction different from the directions that the signal wave and the pump wave transmit, and therefore the energy reflow is suppressed when the optical parametric amplifier has reached saturated amplification, and the performance of the optical parametric amplifier is significantly improved.Type: ApplicationFiled: April 10, 2018Publication date: August 16, 2018Inventors: Haizhe Zhong, Ying Li, Changwen Xu, Jianlong Yang, Shiwei Wang, Dianyuan Fan

Publication number: 20180231871Abstract: A depth estimation method for a monocular image based on a multi-scale CNN and a continuous CRF is disclosed in this invention. A CRF module is adopted to calculate a unary potential energy according to the output depth map of a DCNN, and the pairwise sparse potential energy according to input RGB images. MAP (maximum a posteriori estimation) algorithm is used to infer the optimized depth map at last. The present invention integrates optimization theories of the multi-scale CNN with that of the continuous CRF. High accuracy and a clear contour are both achieved in the estimated depth map; the depth estimated by the present invention has a high resolution and detailed contour information can be kept for all objects in the scene, which provides better visual effects.Type: ApplicationFiled: December 14, 2016Publication date: August 16, 2018Inventors: Xun Wang, Leqing Zhu, Huiyan Wang
