  1. 1. Wireless electrocardiogram based on ultra-wideband communications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Maria Toll; [2019]
    Nyckelord :UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

    Sammanfattning : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).

  2. 2. Design and Evaluation of a Real-Time Sensor Monitor System on Raspberry Pi using Xenomai

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Rene Gonzalez; [2019]
    Nyckelord :;

    Sammanfattning : A real-time system computes information before a deadline in a deterministic fashion.Xenomai is a real-time framework to port real-time industrial applications to Linux. Ithas a dual-kernel architecture, with one kernel dedicated to handling real-time tasksexclusively. This co-kernel operates along with the Linux kernel in the same memoryspace. LÄS MER

  5. 5. Model Predictive Control of Electric Drives -Design, Simulation and Implementation of PMSM Torque Control

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Levente Zsolt Pap; [2018]
    Nyckelord :PMSM; Field Oriented Control; Model Prediction Control; Inverter; Electric Drive; DSP;

    Sammanfattning : The thesis deals with the design of a permanent magnet synchronous machine controller that isimplemented on an embedded platform to replace the off-the-shelf controller currently being used in theelectric race car of the KTH Formula Student team. Software implementation of the control algorithmwas tested in laboratory environment on the hardware prototype of a 2-level three-phase voltage sourceinverter. LÄS MER
