Low-Power Gesture Recognition Using Convolutional Neural Networks and Ambient Lighting

This paper presents a study focused on developing an efficient signal processing pipeline and identifying suitable machine learning models for real-time gesture recognition using a testbed consisting of an Arduino Nano 33 BLE and three OPT101 photodiodes. Our research aims to address the challenges of limited computational power whilst...

Recognising Gestures Using Ambient Light and Convolutional Neural Networks: Adapting Convolutional Neural Networks for Gesture Recognition on Resource-constrained Microcontrollers

This paper presents how a convolutional neural network can be constructed in order to recognise gestures using photodiodes and ambient light. A number of candidates are presented and evaluated, with the most performant being adopted for in-depth analysis. This network is then compressed in order to be ran on an Arduino Nano 33 BLE...

Smart Teddy: Elderly monitoring and support system using ambient intelligence: Human Interaction and Integration

In September 2018, the Smart Teddy project was founded by a group of researchers within the Hague University of Applied Sciences1 in the Netherlands. The Smart Teddy project is a multidisciplinary project aiming to create an interactive system, using a teddy bear as a focus point, which collects the data needed in order to enable seniors with...

Sensor Patch: Subgroup: Microcontroller and Communication

This research investigates the feasibility of a sensor patch for newborns. A sensor patch would be a device that is applied to the skin of the newborn. It can monitor the patient's temperature, heart rate, respiration rate, oxygen saturation and asses its general appearance of the skin so that it can check the newborn for jaundice. It should...

Designing an Innovative Brake Control System

Current trailers and caravans use overrun brakes, which cause overheated brakes in the mountains. A solution is to design an electric brake system in which the brakes are controlled electronically instead of mechanically. The report discusses the control models associated with braking, anti-sway detection and velocity sensor fusion. The RDW...

Keeping water under surveillance: Control

This thesis describes the work of two students who designed the control system of a stand-alone water well measuring system, named SubDowser. The project was done by order of a proposal from the start-up company SkyDowser. The total thesis group, consisting of three subgroups, was asked to build a working prototype which could measure the water...

Design of a controller for an adjustable frictionless resistance fitness device, with wireless user feedback

This report proposes a design for a control system for a variable frictionless resistance training device, that is able to set the resistance and give feedback to the user via a wireless connection. The fitness device uses regenerative braking and information about the generated power is sent back to the user. The variable resistance is set...

Network-based bootloader for distributed embedded systems applications

This thesis describes the design, implementation and deployment of a network-based bootloader for distributed embedded systems applications. The bootloader is based NXP's LPC1769 microcontroller containing the ARM Cortex-M3 processor. The CAN bus is used as the network's physical layer. Due to the modular design of the bootloader, easily...
