  1. 1. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jules Reniaud; [2022]
    Keywords : Technology and Engineering;

    Abstract : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. READ MORE

  3. 2. Characterisation of Satellite Onboard Magnetometer for MIST

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Marcus Mhanna; [2022]
    Keywords : Magnetometer calibration; Ellipsoid Fitting; Helmholtz coil;

    Abstract : The most common equipment used for attitude determination in small satellites are magnetometers. However, using magnetometers gives rise to many challenges. One of these challenges is the calibration of the magnetometer. Magnetometer calibration takes many factors into account. READ MORE

  4. 3. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Joacim Sundh; [2022]
    Keywords : GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  5. 4. Magnetic Moment Characterization for Small Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Alejandro Sans Monguiló; [2021]
    Keywords : small satellite; CubeSat; optical magnetic test bed; magnetic dipole moment characterization; residual magnetic moment; permanent magnet verification; magnetic measurement; Foresail-1; Helmholtz cage;

    Abstract : Small satellites are gaining popularity in a wide range of applications where attitude systems require high precision performance. One of the main sources of errors, in case of magnetic attitude control systems, is the residual magnetic moment (RMM) of the spacecraft. READ MORE
