Optimizing Connection Establishment and Parameter Adaptation in Bluetooth Low-Energy for Intermittently-powered Devices

The growing field of research into batteryless or intermittent systems has enabled Internet of Things applications that were previously impossible. For example, the FreeBie system recently introduced Bluetooth Low-Energy (BLE)<br/>to intermittent devices, making medium to long range bi-directional communication a reality for the first time....

Low Power Bluetooth Baseband with a RISC-V Core for Autonomous Sensors using Chisel

The number of IoT devices and their applications is projected to continue increasing in the future, creating a demand for low-power wireless communications that allow IoT devices to either be connected directly to the internet or to use other devices as a back gate to it. BLE is already one of the most used wireless communication protocols for...

Creating seamless self-checkout areas in supermarkets using automatic customer exit control

This thesis is result of an assignment set up by Pan Oston. Pan Oston is a company who makes steel product like checkouts and kiosks for the retail market. A sizable part of Pan Oston’s revenue are checkouts and self-checkouts (SCOs). It is expected that in the future of retail these products are less relevant. This is why Pan Oston has...

Exploring Gamification in Extreme Sports

This master thesis sets out to develop a product / service designed for the most valuable metric (across multiple action sports) and to present a gamified experience of this metric to the user. The thesis presents a roadmap stating what (action) sports should be targeted: kiteboarding, wakeboarding, snowboarding, surfing, and skateboarding. The...

Radio Propagation Aided Indoor Localization: Indoor localization by applying Proportionate Measurement Localization (PML) using Bluetooth Low Energy tags

Indoor localization is a hot topic since the demand for Location Based Services (LBS) has increased, especially (semi) public places like museums, office buildings and congress halls would benefit from LBS. Outdoor localization and its applications like navigation systems are well implemented in society and used by many on a daily basis....

Researching the BLE based intelligent lighting control system

Several leading lighting companies for example NXP and Philips work in a project to explore the next generation intelligent lighting system. One innovation of the project is using a distributed architecture to replace current centralized system to increase robustness and extensibility. As a core component of wireless lighting control system,...
