  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

  4. 3. Design and implementation of an energy harvesting system in a prosthetic limb

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

    Författare :Ódinn K. Rúnarsson; [2023]
    Nyckelord :Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER

  5. 4. 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

  7. 5. 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.
