  1. 1. Utvärdering av en radarbaserad andningssensor

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronikUmeå universitet/Institutionen för strålningsvetenskaper

    Författare :Kevin Johansson; [2018]
    Nyckelord :;

    Sammanfattning : In today's health care it is important to study and monitor vital parameters to diagnose respiratory diseases and have the ability to intervene in possible respiratory arrest. The XeThru X2M200 is new on the market and uses Ultra Wideband (UWB) radar technology to detect inhalation and exhalation. LÄS MER

  2. 2. Quai-Passive 5.8 GHz Front-End Design and Implementation for Vital Signs Detection

    Master-uppsats, Linköpings universitet/Fysik och elektroteknikLinköpings universitet/Tekniska högskolan

    Författare :Henrik Kalvér; [2018]
    Nyckelord :;

    Sammanfattning : This thesis investigates the possibility to measure vital signs, such as heartbeat and respiratory rate, by developing a RF-front end for wireless detection. The RF-front has been developed and manufactured as a continuous wave Doppler radar receiver, which utilizes quadrature demodulation by means of a multi-port correlator together with power detectors for down conversion.

  3. 3. Smartphone physics – a smart approach to practical work in science education? : Experiences from a Swedish upper secondary school

    Uppsats för yrkesexamina på avancerad nivå, Stockholms universitet/Institutionen för matematikämnets och naturvetenskapsämnenas didaktik

    Författare :Tomas Svensson; [2018]
    Nyckelord :Science education; practical work; laboratory work; ICT; didactical design research; teacher research; smartphones; video analysis; programming; Python; MatLab; Laborationer; didaktik; smarta telefoner; videoanalys;

    Sammanfattning : In the form of teacher didactical design research, this work addresses a didactical issue encountered during physics teaching in a Swedish upper secondary school. A need for renewed practical laboratory work related to Newtonian mechanics is met by proposing and designing an activity based on high- speed photography using the nowadays omnipresent smartphone, thus bringing new technology into the classroom.

  5. 5. Design of a metal detector

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Ammar Haider; [2018]
    Nyckelord :Antenna; Radar; Frequency;

    Sammanfattning : Electromagnetic wave propagation is a well-known phenomenon in the scientific world and when the first telescope was built method of sensing objects excelled afterwords. Research in optical system and infrared is growing day by day but radar system still dominates the world in object sensing. LÄS MER
