  1. 1. Towards Long-Range Backscatter Communication with Tunnel Diode Reflection Amplifiers

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Gustav Eriksson; [2018]
    Keywords : Amplified backscatter tag; Reflection amplifier; Battery-free; Long-range communication; Tunnel diode; Ultra-low power consumption; RFID; Frequency shift;

    Abstract : Backscatter communication enables wireless communication at a power consumption orders of magnitude lower than conventional wireless communication. Instead of generating new RF-signals backscatter communication leverages ambient signals, such as WiFi-, Bluetooth- or TV-signals, and reflects them by changing the impedance of the antenna.

  2. 2. Self-Tuning NFC Circuits

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

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

    Abstract : 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.

  3. 3. Wristband Design for Pool Safety System : Redesign of Multifunctional Wearables for Drowning Detection

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle; Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Jonas Larsson; Johan Carlén; [2017]
    Keywords : Industrial design engineering; pool safety; human-centred design; wristband design; wearables; Teknisk design; poolsäkerhet; användarcentrerad design; armbandsdesign; wearables;

    Abstract : Every year, people are injured or even drowns in pools all over the world. Even in pools with monitoring lifeguards, accidents happen. One reason for submerge injuries or drownings is that they often are silent, which make incidents hard to detect. READ MORE

  4. 4. Radio Based User Presence

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Ana Rosalía Santamaría Portolés; [2015]
    Keywords : RFID; HF; RFID limitation; reading distance limitation; SIP; user detection; user location; RFID; HF; RFID begränsning; läsavstånd begränsning; SIP; användardetektering; användarens plats;

    Abstract : While radio frequency identification tags (RFIDs) have been widely used for identifying objects (and some people), their primary use has been for access control, inventory, and other similar purposes. In this thesis we will use the detection of an RFID to indicate that a user is present in a given location. READ MORE

  5. 5. A Self-organized Wireless Sensor Network (WSN) for a Home-event Managed System : Design of a cost efficient 6LoWPAN-USB Gateway with RFID security

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sergio Floriano Sanchez; [2015]
    Keywords : ;

    Abstract : Wireless Sensor Networks (WSN) have existed for many years in industry applications for different purposes but their use has not been fully extended to the global consumers. Sensor networks have lately resulted to be greatly helpful to people in everyday life, specially in home automation applications for monitoring events, security, and control of devices and different elements in the house by using actuators.
