  1. 1. Multiplexing NFC Antennas : An evaluation of the technique and its limitations

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Viktor Gustafsson; Per Ottosson; [2023]
    Nyckelord :AAT; BER; DSR; Impedance; Multiplexer; NFC; Wireless Technology;

    Sammanfattning : Introduction This study aims to investigate the possibility of driving multiple NFC antennas with a single NFC-controller by using a multiplexer. An artifact was developed and experiments were conducted in order to evaluate the design choice and in addition, to observe the impact of a multiplexer in an NFC system with respect to the number of successful tag detections, bit error rate (BER), the utilization of automatic antenna tuning (AAT) and the physical distance to the NFC tag.

  3. 2. Integrity and Security Considerations of Transparency and Traceability : an Exploratory Case Study of Traceability Validation Systems

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Caroline Löwenhav; Hanna Tingsvik; [2022]
    Nyckelord :Transparency; Traceability; Social Perspective; Integrity; Security; Traceability Validation System; Exploratory Research;

    Sammanfattning : Background: In recent years, unfair and unsafe working conditions have been reported, raising concerns among stakeholders and end-users. The demand for fashion brands to take further responsibility for social sustainability and transparency has increased. LÄS MER

  4. 3. To Create the Perfect Self-Repair Experience for an Induction Hob

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Rodrigo Díaz Salvadores; Josefin Franzén; [2022]
    Nyckelord :Circular economy; Induction hob; Design for circularity; Cirkulär ekonomi; Induktionshäll; Cirkulär design;

    Sammanfattning : This project was performed in collaboration with Electrolux and takes off in the transition towards a circular economy where products are considered to have multiple life cycles and need to be designed to be able to cycle longer through maintenance and repair. Electronics are rarely designed to fit into circularity thus an induction hob was chosen to show this principle. LÄS MER

  5. 4. Self-Tuning NFC Circuits

    Master-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Yimeng Li; [2017]
    Nyckelord :Parallel capacitance compensation; RFID system; NFC; Self-tuning NFC; Digitally tunable capacitor;

    Sammanfattning : Contactless automatic identification procedures which are called RFID systems (Radio-frequency Identification) have become very popular in recent years for transferring power and data. With the development of RFID technology, the demand of easy transmitting of short data packages has made NFC (Near-field Communication) technology wildly used especially in mobile applications.

  7. 5. Wireless Body Area Network for Patient Monitoring in Hospitals

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Divya Vinod Kalkotwar; [2016]
    Nyckelord :IEEE 802.15.4; wireless body area network; beacon mode; CSMA CA; NFC; patient monitoring.;

    Sammanfattning : The master thesis is a prototyping project of a wireless body area network (WBANs) for patient monitoring in hospitals. The goal of this project was to study various technologies suitable for wireless body area networks, complete a requirement analysis, design a WBAN suitable to achieve the requirements and to test and evaluate the system against the requirements.
