  1. 16. Phased Array Ultrasonic Testing of Austenitic Stainless Steel Welds of the 11 T HL-LHC Dipole Magnets

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Marcus Lorentzon; [2018]
    Keywords : Phased Array Ultrasonic Testing; PAUT; Non-Destructive Testing; Austenitic Stainless Steel; Welds; CERN;

    Abstract : A routine non-destructive test method based on Phased Array Ultrasonic Testing (PAUT) has been developed and applied for the inspection of the first 11 T dipole prototype magnet half shell welds, and the test results are compared with the radiography and visual inspection results of the same welds. A manual scanner and alignment system have been developed and built to facilitate the inspection of the 5. READ MORE

  3. 17. A System Study Of Ultrasonic Transceivers For Haptic Applications

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Ishan Arya; Viswanaath Sundaram; [2018]
    Keywords : Haptics; Ultrasonic; Transceivers; Beamformation;

    Abstract : We are investigating the use of ultrasound in Haptic applications. Initially abrief background of ultrasonic transducers and its characteristics were presented.Then a theoretical research was documented to understand the concepts that govern haptics. READ MORE

  4. 18. Visual feedback to sonar clicks

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Fredrik Mårtensson; [2017]
    Keywords : Technology and Engineering;

    Abstract : The wildlife park Kolmården in Norrköping, Sweden, asked for a device that could visually feedback how dolphins use their ultrasound signals while echolocating objects. By recording the sound from the dolphin, process the sound and then create a visual feedback by having LED's flash in different frequencies, depending on the distance between dolphin and device.

  5. 19. Ultrasonic Positioning System for Electric Road System

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Marcus Romner; Robin Hedlund Johansson; [2016]
    Keywords : Elonroad; Ultrasonic; Ultrasound; ERS; Electric Road System; Ultrasonic Positioning System; Electric Vehicle; Technology and Engineering;

    Abstract : Elonroad is a company that is looking into the possibility to charge electric vehicle on road. The conductor implemented on the driveway has a characteristic shape. The scope of this master thesis project is to identify the shape of the conductor and determine the relative position of the vehicle to the conductor using ultrasonic sensors. READ MORE

  6. 20. Automation of ultrasonic Time-of-Flight technique for saw log classification using signal processing

    University essay from Uppsala universitet/Signaler och System

    Author : Sean Chuong Le Hoang; [2015]
    Keywords : Time-of-Flight; ultrasonic; saw log;

    Abstract : The thesis project is aimed to automate ultrasonic Time-of-Flight (ToF) technique for saw log classification using signal processing. The ToF technique works in such a way that ultrasonic tone-burst pulses are sent into a saw log, and then the ToF that the pulses take for the propagation is measured and used to calculate the sound speed and further, the Modulus of Elasticity (MoE).
