    Sammanfattning : Around 40 million people around the world have amputated parts of their bodies. Prostheses are widely used to support their daily behavior. However, about 35% of amputees refuse to use the prostheses due to comfort problems. SocketSense is an EU research project that aims to improve the situation. LÄS MER


    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Nyckelord :;

    Sammanfattning : BAE Systems Hägglunds are using contactors to control the power supply in their vehicle,but a replacer has been developed because the contactors take up a lot of space. The replacer is a self-designed semiconductor switch, which is called Ultra High Power DigitalOutPut or UHPDOP. LÄS MER

  3. 3. Integrated DC fast charger in an electric vehicle

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Christoffer Johansson; Axel von Keyserlingk; [2022]
    Nyckelord :Boost converter; DC charging; Electric machine; Inverter; Electric vehicle; Technology and Engineering;

    Sammanfattning : More and more electric vehicles are emerging with a nominal battery voltage higher than what most older DC fast chargers are capable of charging. This requires the vehicle manufacturers to include a high power DC to DC converter in order to be able to charge at these stations, adding cost and complexity. LÄS MER

  4. 4. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Tim Wiik; [2022]
    Nyckelord :Sensor fusion; UAV; UGV; NIR-LED; Extended kalman filter; Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; GNSS-denied Scenario;

    Sammanfattning : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.
