    Sammanfattning : Wireless transmission is an everyday part of movie production and a tool many people use in their work. Work, on a movie production, is fast, intense, and varies in geographical location almost on a daily basis (sometimes several locations in a day). Despite this, the stream, the transmission, must hold so the crew can work. LÄS MER

  3. 2. Battery-free Visible Light Sensing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för datorteknik
