  1. 21. RF Energy Harversting : Design and implementation of an RF energy harvesting system for SoC

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Erlend Sanden; [2019]
    Nyckelord :Power management; radio frequency harvesting; low power device;

    Sammanfattning : This assignment was given by Nordic Semiconductor. In this project a radio frequency energy harvesting system able to harvest ambient power at 900 MHz (GSM) was simulated and designed. A Villard voltage multiplier, boost converter and power management circuit was implemented for the harvesting system. LÄS MER

  3. 22. On-board Driver’s Assistance and Assessment System

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Paweł Damps; Jacek Czapla; [2018]
    Nyckelord :Driver’s Behaviour; Driver’s Evaluation; Driving Style; Eco-Driving; Internet of Things; Real-Time Vehicle Tracking; Skills Assessment; Spider Chart;

    Sammanfattning : The goal of this work is a design and implementation of an on-board driver’s assistance and assessment system. The system overcomes the problem that typical evaluation of skills is performed by experts who may be subjective and are able to consider only a limited number of factors and indicators. LÄS MER

  4. 23. Implementation of a Water Flow Sensor Node and Energy Evaluation of 2G Transmission Strategies

    M1-uppsats, Linköpings universitet/Institutionen för datavetenskap
