  1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Franz Wikner; [2024]
    Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

    Sammanfattning : Today, a large number of devices with small form factors and limited resources are being integrated with processes to perform complex tasks such as localization and mapping. One example of this are headsets used for Extended Reality. LÄS MER

  4. 3. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Emil Lydell; [2023]
    Nyckelord :Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Sammanfattning : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. LÄS MER

  5. 4. A small step for a sensor : Detecting limited spatial movement with mobile AR

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Johan Fallström; [2023]
    Nyckelord :computer-science; software; development; software development; ar; augmented reality; unity; ar foundation; arkit; arcore; exergame; heart failure; rehabilitation; world tracking; mobile ar; mobile augmented reality; movement tracking; p-iii; heart-exg; exergaming; step counter; spatial movement; slam;

    Sammanfattning : In this paper, a technical overview will be provided for a developed mobile exergame, with a particular focus on its movement tracking. By utilizing spatial movement readout from the AR algorithm, we've managed to create an easy to use exergame that allows the user to track their horizontal movement. LÄS MER
