1. 21. Medical Signal Preparation and Proof of Concept for a Display and Diagnosis Application : Transmission, Display and QRS detection of an ECG Signal

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : David Fogelberg Skoglösa; [2021]
   Keywords : Signal display; Analog to digital conversion; QRS-detection; Application ECG-diagnosis; Real-time.;

   Abstract : In many developing countries health care conditions are poor and there is a lack of healthcare professionals and diagnostics tools. Cheap and easy-to-use diagnostics tools have been developed to make practicing medicine easier under these conditions. READ MORE

3. 22. Wireless Power Transfer in Cavity Resonator

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Axel Djurberg; Fredrik Forsberg; Anton Lind; Ludvig Snihs; [2021]
   Keywords : cavity; resonator; radio frequency; wireless power transfer;

   Abstract : The purpose of this paper is to achieve wireless power transfer inside a resonating cavity, and thereby apply this to charge batteries. The idea is to convert radio frequency waves into direct current, which can charge the batteries. This was done by creating an LC-antenna, which in turn was connected to a rectifier. READ MORE

4. 23. Light Rail Camera - an EMC-assessment

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Isak Stjernrup Öberg; Viktor Drakfelt; [2021]
   Keywords : Light; Rail; Camera; EMC; EMI; EM; PLC; Power; Line; Communication; Axis; Electrical; Measurement; Technology and Engineering;

   Abstract : When installing multiple security cameras the cable management can be a struggle. Historically cameras need one cable for power and one for communication, however, advancements in power over ethernet have reduced the number of cables down to one. READ MORE
