  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.

  3. 2. Teleoperation of an Autonomous Ground-Penetrating Radar for Non-Destructive Surveying: Design and Implementation

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

    Författare :Rasmus Beyer; [2023]
    Nyckelord :Autonomous; GPR; Robotics;

    Sammanfattning : A lot of features that need to be scanned underground should not be disturbed, from waterlines to unmarked graves. A non-invasive way of probing underground is Ground-Penetrating Radar (GPR). GPR finds differences in materials with radar waves. However, GPR is human-operated and its position is generally determined with a GPS. LÄS MER

  4. 3. New technology for smart traffic lights based on the Arduino microcontroller

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Bassam AL Anbagi; [2023]
    Nyckelord :smart traffic lights;

    Sammanfattning : Abstract Society has changed immensely due to the revolution in information technology. The question is how this technology can be useful to man. My interest lies in how to apply radar to traffic. People in general relate radar to military matters while the focus here is on traffic accidents. LÄS MER

  5. 4. Laser dazzling of CMOS imaging sensors using amplitude modulated and continuous wave lasers

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Johan Fjellström; [2023]
    Nyckelord :;

    Sammanfattning : Protecting sensitive information is important, especially in defence applications. As cameras become more common, developing countermeasure systems that limit the information gathering capabilities of imaging sensors would be beneficial. LÄS MER

  7. 5. Static Extrinsic Calibration of a Vehicle-Mounted Lidar Using Spherical Targets

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

    Författare :Philip Sandström; [2023]
    Nyckelord :;

    Sammanfattning : Self-driving cars are steadily becoming a reality by a growing number of driver assistance functions enabled by smart perception sensors. The light detection and ranging (lidar) sensor show great potential for perception tasks due to its precise distance measurements. LÄS MER
