Publication number: 20220036744Abstract: This invention discloses a system to automate a non-destructive test (NDT) for measuring stress or stress change developed within an object during a certain time period by using unmanned aerial vehicles (UAV) and ultrasound technique. The system comprises a ground control station (GCS), UAVs and reference positioning modules as its basis. Given a test plan containing test points over a surface of a test object in 3D point coordinates, UAVs can fly autonomously to the points and perform ultrasound measurements on them with a single or a plurality of ultrasound transducers in an automated manner. Moreover, after receiving trigger signals from the GCS, a UAV can also perform the flight and the measurement synchronously with other UAVs. After a measurement, an acquired ultrasound echo signal is taken with another echo signal acquired at a different time point to compute stress or stress change.Type: ApplicationFiled: August 2, 2020Publication date: February 3, 2022Inventor: Yoshikazu Yokotani

Patent number: 10984810Abstract: An audio decoder provides a decoded audio information on the basis of an encoded audio information including linear prediction coefficients (LPC) and includes a tilt adjuster to adjust a tilt of a noise using linear prediction coefficients of a current frame to acquire a tilt information and a noise inserter configured to add the noise to the current frame in dependence on the tilt information. Another audio decoder includes a noise level estimator to estimate a noise level for a current frame using a linear prediction coefficient of at least one previous frame to acquire a noise level information; and a noise inserter to add a noise to the current frame in dependence on the noise level information provided by the noise level estimator. Thus, side information about a background noise in the bit-stream may be omitted. Methods and computer programs serve a similar purpose.Type: GrantFiled: February 26, 2019Date of Patent: April 20, 2021Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Guillaume Fuchs, Christian Helmrich, Manuel Jander, Benjamin Schubert, Yoshikazu Yokotani
