  1. 1. Bluetooth audio codecs in a real-time interactive context

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Gustav Johansson; Mattias Adevåg; Jacob Milton; [2023]
    Nyckelord :Bluetooth Low Energy; BLE; audio codec; LC3; aptX; real-time; interactive context; latency; perceived audio quality;

    Sammanfattning : The emergence of Bluetooth Low Energy in combination with optimized coders has made it possible to transfer digital audio at very low bitrates, paving the way for small devices with longlasting batteries. The aim of this study is to compare the audio codecs LC3 and aptX, as well as peoples’ attitude towards audio quality in different contexts. LÄS MER

  3. 2. The Characterisation and Continuous Measurement of Potential Harvestable Energy of an Environment

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

    Författare :Diran Bajwa; [2023]
    Nyckelord :Photovoltaic; Lux; Lux Metre; Energy Harvesting; PMU; Arduino; IoT; Fotovoltaisk; Lux; Luxmätare; Energiskörd; PMU; Arduino; IoT;

    Sammanfattning : This thesis is based around the use of energy harvesting in systems, specifically for a Bluetooth Low Energy (BLE) mesh testbed. This BLE mesh is located in a well lit lab and is currently powered by mains electricity. Systems such as the BLE mesh are considered Internet of Things (IoT). LÄS MER

  4. 3. Investigating the impact of physical layer transmission for Bluetooth LE Audio

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Kevin Arponen; Axel Björkman; [2023]
    Nyckelord :Bluetooth Low Energy; Energy consumption; LC3; LE Audio; Physical Layer; Throughput; Wireless audio streaming; Wireless communication;

    Sammanfattning : Bluetooth Low Energy (BLE) is a widely used low-energy version of Bluetooth’swireless protocol. To meet increasing requirements of modern wireless audio devices,Bluetooth LE Audio was released with its new Low Complexity CommunicationsCodec (LC3) being much more data efficient than its predecessor Low Complexity SubBand Coding.

  5. 4. Design and Evaluation of a logging system in a power-constrained environment

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

    Författare :Morgan Adamsson; [2023]
    Nyckelord :Low power; logging; embedded systems; power supply; Bluetooth Low Energy; WiFi; flash memory; Låg effekt; loggning; inbyggda system; strömförsörjning; Bluetooth Low Energy; WiFi; flashminne;

    Sammanfattning : Logging plays a crucial role in debugging endeavors, assisting technicians in identifying errors and improving the overall sustainability of electrical systems. This thesis focuses on integrating local logging capabilities into the Balise Transmission Module (BTM), a legacy control system that lacks such features. LÄS MER

  7. 5. IoT - based Microseismic Detector

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Anton Lindgren; [2023]
    Nyckelord :IoT; accelerometer; microphone; BLE; embedded;

    Sammanfattning : Rockfall, which is the detachment of rocks from a mountain, is a major hazard in the mining industry. To help combat this issue, this thesis aims to develop a sensor platform that is able to detect both the potential risk for rockfall and if any rocks do hit the ground. LÄS MER
