Patent number: 10073065Abstract: The invention relates to a continuous monitoring system which will monitor the pipes without the need of shutting down of the plants. The major issues in designing such a system using magnetostriction as per prior art is the loss of magnetization of the permanent magnets used to provide the magnetic bias and also the disbonding of interfaced adhesives with which the magnetostrictive ribbons are bonded at high temperatures. The invention identifies a novel sensor which can be taken up to high temperatures without any loss of signal strength, this is achieved by generating guided waves using a special amorphous magnetostrictive ribbons. L(0, 2) mode waves are generated using these ribbons to monitor pipes working at high temperatures as per the invention.Type: GrantFiled: April 10, 2014Date of Patent: September 11, 2018Assignee: INDIAN INSTITUTE OF TECHNOLOGY MADRASInventors: Krishnan Balasubramaniam, Tarun Kumar Mishra

Patent number: 10073063Abstract: A hollow structure like a pipeline is inspected using an array of ultrasound transmitters located within the hollow structure distributed over different radial directions from a center of the array. Parameters such as ellipticity, defining a shape and/or orientation of an inner surface of a wall of the hollow structure are first determined based on measured delays between transmission of ultrasound pulses from the transmitters to reception of first reflections of those ultrasound pulses. Parameters may be used that define an elliptically shaped cross-section of the inner wall surface for example. Next an ultrasound wavefront composed of joint transmissions from the transmitters along at least a sector of the array is transmitted, using relative time delays between waves transmitted by the respective ones of the transmitters to compensate for estimated differences between travel times from the transmitters to the shape defined by the parameters. Reflections of the joint transmissions are detected.Type: GrantFiled: December 19, 2014Date of Patent: September 11, 2018Assignee: NEDERLANDSE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TNOInventors: Paul Louis Maria Joseph van Neer, Gerrit Blacquiere, Arno Willem Frederik Volker, Huibert Blokland

Patent number: 10060884Abstract: A method of scanning a sample includes simultaneously forming a plurality of co-linear scans. Each scan is formed by a sweep of a spot by an acousto-optical device (AOD). The co-linear scans are separated by a predetermined spacing. A first plurality of swaths are formed by repeating the simultaneous forming of the plurality of co-linear scans in a direction perpendicular to the co-linear scans. The first plurality of swaths have an inter-swath spacing that is the same as the predetermined spacing. The predetermined spacing can be a scan length or an integral number of scan lengths. A second plurality of swaths can be formed adjacent to the first plurality of swaths. Forming the second plurality of swaths can be performed in an opposite direction to that of the first plurality of swaths or in a same direction. An inspection system can implement this method by including a diffractive optical element (DOE) path after a magnification changer.Type: GrantFiled: June 16, 2016Date of Patent: August 28, 2018Assignee: KLA-Tencor CorporationInventors: Jamie Sullivan, Wenjian Cai, Yevgeniy Churin, Ralph Johnson, Meier Yitzhak Brender, Mark Shi Wang, Rex Runyon, Kai Cao

Patent number: 10036735Abstract: Systems and methods are disclosed to enhance three-dimensional photoacoustic imaging behind, through, or inside a scattering material. Some embodiments can increase the optical fluence in an ultrasound transducer focus and/or enhance the optical intensity using wavefront shaping before the scatterer. The photoacoustic signal induced by an object placed behind the scattering medium can serve as feedback to optimize the wavefront, enabling one order of magnitude enhancement of the photoacoustic amplitude. Using the enhanced optical intensity, the object can be scanned in two dimensions and/or a spot can be scanned by re-optimizing the wavefront before post-processing of the data to reconstruct the image. The temporal photoacoustic signal provides information to reconstruct the third-dimensional information.Type: GrantFiled: August 26, 2014Date of Patent: July 31, 2018Assignee: THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATEInventors: Rafael Piestun, Hengyi Ju, Jacob Dove, Antonio Miguel Caravaca-Aguirre, Todd Murray, Donald Conkey
