  1. 1. Bladder Monitoring Using Ultra-Wideband Radar and Vivaldi Antenna

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Erica Jonsson; Attila Kovács; [2023]
    Keywords : UWB; Ultra-wideband; Vivaldi antenna; Bladder monitoring; Radar; Radar design; Ultra-wideband radar;

    Abstract : Millions worldwide cannot tell when their bladder is nearing total capacity. The catheter, a tube to empty the bladder, is a vital part of life for many people. A catheter is, however, not a comfortable option, and it is the most common cause of infection in people staying in hospitals. READ MORE

  3. 2. Estimating Relative Position and Orientation Based on UWB-IMU Fusion for Fixed Wing UAVs

    University essay from Linköpings universitet/Reglerteknik

    Author : Daniel Sandvall; Eric Sevonius; [2023]
    Keywords : UWB; Relative positioning; Sensor fusion; UAV; Formation flight; Fixed wing; Relative localization; EKF; FGO;

    Abstract : In recent years, the interest in flying multiple Unmanned Aerial Vehicles (UAVs) in formation has increased. One challenging aspect of achieving this is the relative positioning within the swarm. READ MORE

  4. 3. Ultra-wideband location tracking of mobile devices

    University essay from Uppsala universitet/Signaler och system

    Author : Daniel Hietarinta; [2022]
    Keywords : UWB; ultra-wideband; GPS; tracking; locating; wireless communication; low-power; embedded systems; mobile devices; OTG; sensors; sensor fusion; mobile app; Android; dynamic anchors; ranging; C; Python;

    Abstract : Today’s most widely used tracking solutions for consumers involve the Global Positioning System (GPS) which meets most needs when it comes to rough estimation of location. GPS however is limited in accuracy with a horizontal error of around 5 meters and cannot be used in the areas where the satellites cannot provide a strong enough signal e.g. READ MORE

  5. 4. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Wassim Wahbeh; Youssef Hasan; [2022]
    Keywords : DARDS;

    Abstract : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. READ MORE

  6. 5. UWB-TWR performance comparison in a hybrid node network

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Oskar Sundin; [2021]
    Keywords : UWB; TWR; CSMA; Token ring;

    Abstract : This thesis investigated the performance of a positioning system that utilised UWB technology where devices regularly shifts between acting as an initiator and as a responder for distance measurements between each other. The goal was to investigate existing positional techniques and to implement a novel network where devices initiates and responds to distance measurement exchanges. READ MORE
