  1. 1. Automatic overcurrent and leakage current sensing in multiple channel NMES systems

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

    Author : Malin Otter; Bashar Jamal Pati; [2023]
    Keywords : Neuromuscular Electrical Stimulation; Current monitoring; Overcurrent sensing; Leakage current sensing; Embedded systems; Instrumentation amplifier; Neuromuskulär elektrisk stimulering; Strömmätning; Överström detektering; Läckström detektering; Inbyggda system; Instrumentförstärkare;

    Abstract : This report presents the development, implementation, and testing of a current monitor system that is specifically developed for testing a neuromuscular electrical stimulation system (NMES). The NMES system, developed by KTH and its academic and industrial partners Karolinska institute and Matrix Muscle Support, incorporates advanced features aimed at preventing cardiovascular diseases.

  3. 2. 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

  4. 3. Preamplifier Design for Active Electrodes in Single-Channel EEG Applications

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

    Author : Thorir Marwan Abed; [2018]
    Keywords : Electroencephalography EEG ; single-channel; active electrode; current feedback instrumentation amplifier CFIA ; DC servo loop DSL ; portability.; Elektroencefalografi EEG ; singelkanal; aktiv elektrod; strömåterkoppling instrumentförstärkare; DC servo loop DSL ; bärbarhet.;

    Abstract : The implementation of portable electroencephalography (EEG) systems has been known to be complex. During ambulation, the integrity of recorded EEG signals is often impaired by motion artifacts and the time and effort required to set up the system is excessive. READ MORE

  5. 4. Pressure Sensor Miniaturization

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Alexia Trolliet; [2014]
    Keywords : ;

    Abstract : As far as the Printed Circuit Boards (PCB) manufacture industry is concerned, for high production volumes, solder paste is applied on the connection pads through customized stencils. This is a very productive method, yet if the design has to be updated, cost is increasing as the stencil should be changed. READ MORE

  6. 5. RF High Power Amplifiers for FREIA – ESS : design, fabrication and measurements

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Linus Haapala; Aleksander Eriksson; [2014]
    Keywords : RF power amplifier; ESS; 352 MHz;

    Abstract : The FREIA laboratory is a Facility for REsearch Instrumentation and Acceleratior development at Uppsala University, Sweden, constructed recently to test and develop superconducting accelerating cavities and their high power RF sources. FREIA's activity target initially the European Spallation Source (ESS) requirements for testing spoke cavities and RF power stations, typically 400 kW per cavity. READ MORE
