  1. 1. Control system and simplified timesynchronization for heterogenous IoT systems with medium time requirements

    University essay from KTH/Hälsoinformatik och logistik

    Author : Jemma Touma; Simon Hejdenberg; [2024]
    Keywords : Internet of Things; time synchronization; wireless sensor networks; network time protocol; Android; Bluetooth; WiFi Direct;

    Abstract : The company QTPIE conducts research on drivers and their unconscious reactions when driving. To help, they use smart devices that today must be individually handled at the start and end of a run, and have individually set timestamps, which can lead to differences between the units when data is entered and collation of the units' data after a run.

  2. 2. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    University essay from Umeå universitet/Institutionen för fysik

    Author : Franz Wikner; [2024]
    Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.
