  1. 1. Wireless electrocardiogram based on ultra-wideband communications

    University essay from Uppsala universitet/Signaler och System

    Author : Maria Toll; [2019]
    Keywords : UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

    Abstract : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).

    Abstract : In this thesis an electrocardiography (ECG) prototype is developed that wireless transfer the ECG measurements to an Android smartphone. The prototype consist of two printed circuit boards (PCBs), an Android smartphone and an automatically tunable notch filter. READ MORE

  3. 3. Estimation of Orientation in a Dual-Tag Ultra Wideband Indoor Positioning System

    University essay from Uppsala universitet/Fasta tillståndets elektronik; Uppsala universitet/Fasta tillståndets elektronik

    Author : Oscar Johansson; Lucas Wassénius; [2019]
    Keywords : UWB; Ultra Wideband; Indoor Positioning;

    Abstract : In this report the feasibility of using a dual-tag setup in an indoor positioning system was investigated. The reason for the dual-tag setup was to be able to estimate both position and orientation. The system was designed using UWB-technology, with an time of flight trilateration algorithm to calculate the position. READ MORE

  4. 4. Positioning and parking analysis for an indoor positioning system : A comparative study between Bluetooth Low Energy and Ultra Wideband technology

    University essay from KTH/Hälsoinformatik och logistik

    Author : August Brodin Kont; [2019]
    Keywords : radio technology; real-time-localization-service; indoor positioning system; Bluetooth Low Energy; Ultra Wideband; accuracy; precision; sensepoint; radioteknologi; realtidslokaliseringstjänst; inomhuspositioneringssystem; Bluetooth Low Energy; Ultra Wideband; noggrannhet; precision; sensepoint;

    Abstract : The work done in this report as requested by H&D Wireless is performed by using an already developed real time positioning system called Griffin Enterprise Positioning Service and integratingit with ultrasound sensors for presence detection in order to enable assets to park in a visualized environment being actualized by tagging the asset with radio technology hardware. The testing environment was deployed with radio technology hardware equipped for transmitting and receiving radio signals for position estimation of tagged objects where hardware tags emits radio signals being received by sensing radio technology chips called sensepoints which also serves as communication links for further data processing.

  5. 5. Online Collaborative Radio-enhanced Visual-inertial SLAM

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Viktor Tuul; [2019]
    Keywords : ;

    Abstract : Simultaneous localization and mapping (SLAM) allows robots and other devices to localize and navigate in environments by using a map which itself generates. SLAM for single agent applications has matured and is showing promising results, thus the interest for collaborative SLAM has increased. READ MORE
