  1. 1. Control system and simplified timesynchronization for heterogenous IoT systems with medium time requirements

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Jemma Touma; Simon Hejdenberg; [2024]
    Nyckelord :Internet of Things; time synchronization; wireless sensor networks; network time protocol; Android; Bluetooth; WiFi Direct;

    Sammanfattning : The company QTPIE conducts research on drivers and their unconscious reactions when driving. To help, they use smart devices that today must be individually handled at the start and end of a run, and have individually set timestamps, which can lead to differences between the units when data is entered and collation of the units' data after a run.

  3. 2. Robust Multi-Modal Fusion for 3D Object Detection : Using multiple sensors of different types to robustly detect, classify, and position objects in three dimensions.

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

    Författare :Viktor Kårefjärd; [2023]
    Nyckelord :Computer Vision; 3D Object Detection; Multi-Modal Fusion; Deep Learning; Datorseenden; 3D-objektdetektion; Multimodal fusion; Djupinlärning;

    Sammanfattning : The computer vision task of 3D object detection is fundamentally necessary for autonomous driving perception systems. These vehicles typically feature a multitude of sensors, such as cameras, radars, and light detection and ranging sensors. LÄS MER

  4. 3. Assessment of Lower Limb Muscle Strength: Feasibility and Implementation on Exxentric’s SingleExx Machines

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Maximilian Geisler; [2023]
    Nyckelord :Force measurement; Lower limb strength; Symmetry assessment; Flywheel-based leg extension machine; Prototype development; Isokinetic dynamometer; Kraftmätning; Styrka i nedre extremiteterna; Symmetribedömning; Flywheel- baserad benförlängningsmaskin; Prototyputveckling; Isokinetisk dynamometer;

    Sammanfattning : Measuring lower limb strength and symmetry is a common practice in elite sports to determine the return to sports point in time during rehabilitation, and this information could be useful for amateur athletes too. However, the devices used for this are highly sophisticated and hardly accessible. LÄS MER

  5. 4. Association of a Wristband PPG and an ECG Sensor - Analysis, Synchronization and Robustness

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Mattéo Hochart; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Context: The CardioHolter, developed by Kaunas Institute of Technology, Lithuania, has been used in previous studies on cardiovascular behavior at the Department of Biomedical Engineering at Lund University. This equipment associates two finger photoplethysmography (PPG) sensors and an electrocardiogram (ECG) sensor. LÄS MER

  7. 5. Bluetooth low energy mesh logger

    Kandidat-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Oskar Olsson; Ossian Sandell; [2022]
    Nyckelord :IoT; Bluetooth Low Energy; Mesh; synchronization; nRF; Zephyr; SoC; 9-DoF sensor; Technology and Engineering;

    Sammanfattning : This thesis aims to make a prototype that does sampling from gyroscopes, accelerometers and compasses with as little as one millisecond difference between every unit that samples. Longer term tests to gather data of the characteristics of the Bluetooth low energy mesh were made. LÄS MER
