Digital implementation of motional feedback in a bass loudspeaker

This thesis report focuses on possible methods of digital implementation of motional feedback in a bass loudspeaker. In this thesis, the control system will be created for a monopole and a dipole speaker specifically. It does so by sketching the outlines of such a system and examining possible designs for the components required to suppress...

Measurement Light Bulb: Light source and camera synchronization

This document describes the design process the prototype of a measurement light bulb which is able to project spherical harmonics of orders 0-1-2. Photographs of these projections can be combined to represent many light distributions. The measurement light bulb can be used in the field of research focused on the computation of the illumination...

Measuring Device for Controlling a Vaporising Liquid Microthruster

The objective of the project is to design a system which can control the temperature of a va-porizing liquid microthruster (VLM). The liquid in a VLM is heated using a heater resistor.This resistor will be used to both heat the liquid and measure the temperature.In this thesis the subsystem responsible for the measurements and the conversion of...

Instrumented Skeleton Sled: Focussing on Data Processing and User Interface

This report details the design of an instrumentation system to be used on a skeleton sled. The system will measure several quantities on a skeleton track for the athlete to learn from. This data is stored during the run using several sensors on the sled and processed and visualised immediately afterwards on a mobile device. The project is tailor...

Instrumented Skeleton Sled: Focussing on force and orientation sensing

This report details the design of an instrumentation system to be used on a skeleton sled. The system will measure data during the run on a skeleton track using several sensors and process and visualise the data afterwards in order to shorten the learning curve of the athlete and give quantitative feedback. The subsystem discussed in this report...

Design and fabrication of a measurement interface for smart IoT sensors: Signal generation and hardware control

This project is to design and implement a reconfigurable measurement interface for Internet of Things sensors, for the Microelectronics Department of the Delft University of Technology. This thesis will discuss the functionality and design process taken in designing such a reconfigurable measurement interface, focusing on generating signals and...

The role of dockless shared-bikes in Delft: From a user perspective

This thesis provides an insight into the role of dockless shared-bikes (Mobike) in Delft. The objective of is to fill the knowledge gap about the users of shared-bicycles and their motivations to use shared-bikes in Delft. A survey is and finally gained 91 useful results. 76% of respondents are students, and in general, people are highly...

Wireless Charger for Hand-held Mobile Devices: EE3L11 - BSc Project: Final Thesis

In recent years the field of wireless charging has seen remarkable developments. More and more devices like mobile phones and laptops can be charged wirelessly, and larger equipment like electric vehicles are likely to follow the same path. The air gaps over which the power can be transferred keeps increasing, as do the <br/>amount of power that...

Design of an AutonomousWireless Weather Station: EE3L11 - Bachelor Graduation Thesis

With increasingly changing climates, measuring the weather on remote, off-grid locations has become more important in order to accurately track emerging weather patterns. Cheap and easy access to meteorological information allows communities and individuals to better manage agricultural development, track localised extreme weather events, and...

High precision Analog-to-Digital Conversion: Nuna Sensor System

This thesis is part of the development of a sensor system for measuring currents in the Nuna solar car. A big problem within this system is the processing of incoming sensor data. Therefore, a solution in the form of a sensor-data-processing-unit was proposed, with its primary focus on the analog-to-digital conversion. The converter should not...

Motion Reference Unit Testing Platform: Software

The Motion Reference Unit (MRU) is an important component in the Ampelmann Operation B.V. systems. In order to assess the performance of different MRUs a test system is developed. By using a one Degree of Freedom rail, wave motions can be simulated in the sway, surge and heave direction of a ship. The test system is divided in three parts:...

Motion Reference Unit Testing Platform: MRU Assessment

In order to make offshore working conditions safer, Ampelmann B.V. builds platforms that stay stable by compensating for a ship’s motion. These platforms are controlled via motion reference units (MRUs). In order to test the performances of these MRUs, a linear motion MRU test setup was developed. The system was divided into three parts:...

Sound localization using an array of Acoustic Vector Sensors: Mainstation data processing

In this thesis five different Direction Of Arrival algorithms will be developed for use with Microflown's Acoustic Vector Sensors, which will determine the direction an acoustic signal originates from. These algorithms will run on a main-station that will remotely receive data from an array of AVSs. The performance of these algorithms is...

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...
