Patent number: 11959164Abstract: This invention provides a process or fabrication method of forming broadband anti-reflective (AR) coating over the mid-IR fluoride fiber for high power laser applications in mid-IR wavelength range. The AR coating consists of multiple-pair Lithium fluoride (LiF) and Al2O3, and was deposited by electron beam physical vapor deposition with an iron assistant source at low temperature (<60° C.). A thin encapsulation layer of Al2O3 was applied over the AR coating by atomic layer deposition technology. The measurements show the coating has a reflectivity of <1-1.5% in the range of 1.5-5.5 ?m. The laser induced damage threshold (LIDT) test shows the damage threshold is greater than 8.9 MW/cm2 with no sign of any damage on the coating exposed to atmosphere. The durability and environmental tests of the AR coating with PVD coated encapsulation layer show good humidity resistance in open air and no degradation of film quality and optical performance are observed.Type: GrantFiled: March 10, 2022Date of Patent: April 16, 2024Inventors: Yimin Hu, Feng Niu, Wei Lu

Patent number: 8107541Abstract: A method segments a video. Audio frames of the video are classified with labels. Dominant labels are assigned to successive time intervals of consecutive labels. A semantic description is constructed for sliding time windows of the successive time intervals, in which the sliding time windows overlap in time, and the semantic description for each time window is a transition matrix determined from the dominant labels of the time intervals. A marker is determined from the transition matrices, in which a frequency of occurrence of the marker is between a low frequency threshold and a high frequency threshold. Then, the video is segmented at the locations of the markers.Type: GrantFiled: November 7, 2006Date of Patent: January 31, 2012Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Ajay Divakaran, Feng Niu, Naveen Goela
