Visible Light Communication (VLC) is becoming an important research area where Visible Light Sources such as LED, Halogen Lamps and even the sun can be used for Wireless Communication. LED-to-Camera Communication is a form of VLC, where the camera can notice intermittent stimuli changes above a certain threshold frequency (flicker fusion...

Visible Light Communication is a method of wireless communication that avoids the oversaturated frequencies used by radio communication. Prior research typically uses the camera on smartphone for communication, but using a camera is energy-intensive and inefficient. Some alternatives are photodiodes and ambient light sensors, however the former...

Labour in the agricultural sector is in short supply, while a large portion of the work is still being done manually. To speed up the work and guarantee the food supply of the future, Lely has started a project on agricultural automation. The aim of the project is to create a robot that can perform multiple repetitive tasks simultaneously, to...

Although the demand for wireless communication continuous to grow, the number of frequencies available in traditional data transmission is limited. Visible Light Communication (VLC) is a promising alternative communication method proven to work on high-end devices. However, large-scale adoption requires VLC to also work on everyday machines. Yet...

Visible Light Communication (VLC) has seen drastic improvements in recent years, one approach uses active light sources like LEDs, switching them at hight speeds to send data. Another approach uses the fundamental characteristics of liquid crystals (birefringence and thickness) to transmit data to a single pixel receiver. These characteristics...

Monitoring and analyzing human movement is used in many fields, ranging from healthcare and industrial applications to sports analytics. To provide a football player or their coach with insight into their performance during a game, or their technical development over time, many methods are available such as camera setups and smart vests. However...

As more and more devices have become wireless, the traditional Radio Frequency (RF) spectrum has become densely populated. To relieve this pressure,<br/>communication using light, visible light communication (VLC), has been proposed by many researchers. However, not all light sources can be modulated<br/>to transmit information. Therefore, the...

Software testing is an integral part of the development of embedded systems. Among other reasons, tests are frequently used to ensure that a system meets all the specifications, which is especially important when designing systems for the medical industry. Software changes that have a detrimental impact on a real-time system's performance can...

Achieving consensus in a network is one of the most important performance bottlenecks in distributed computing. This paper takes a look at the existing protocols for achieving Byzantine Reliable Broadcast on asynchronous partially connected networks and how these protocols change to leverage the fact that some nodes have access to Trusted...

The company Kien 1 is developing Bluetooth Low Energy (BLE) speakers, consisting of a subwoofer and several satellite speakers. These subwoofer and satellite speakers will have a feature named Follow Me, which when enabled from a smartphone application, will play music only in the room where the user currently is. The BLE’s signals will...

More and more devices are gaining some form of smartness either by sensing their environment on their own or by communication. An example of this is Smart Lighting, a field in which Chess Wise is active for over 6 years. By adding sensors and communication lighting can be controlled more efficiently. For example motion sensors to turn off...

An Indoor Positioning System (IPS) is being developed at TOPIC Embed- ded Systems to track equipment in hospitals. The system should prevent the loss of equipment en make procedures more efficient. The IPS will con- sist of anchors and tags. Anchors are the radios that form an infrastructure in the building to localise tags that are placed on...

The performance of gun and rocket propellants, which consist of energetic materials, is largely determined by their geometry and composition. Con- ventional production methods limit the performance by putting constraints on both. With additive manufacturing, or 3D-printing, there are signi- cantly fewer geometry constraints and together with the...

The off-side rule is the most complicated rule in soccer. Today, off-sides are determined with the help of referees running on the sides of the field or with the help of cameras. However, for lower league games the installation of a camera based system is very expensive. <br/><br/>This work proposes a sensor based system that can be worn by...

The Internet of Things (IoT) is expected to include billions of tiny devices that collect, process, and communicate sensory data. As of now, batteries power these devices. Batteries, however, are large, expensive, and short-lived - even the rechargeable ones wear out in a few years. Therefore, they are not a sustainable powering solution. Tiny...

A robot swarm of zebros (Dutch: ZEs Benige RObots) is being developed at the TU Delft, with the purpose of forming a large self-deploying sensor network that survey remote locations without the need for any pre-existing infrastructure, or be used for evaluating swarming algorithms in the field. Towards this goal, zebros need to be able to...

Tock is an embedded operating system that can run multiple concurrent, mutually distrustful processes, concurrently. Tock is written in Rust, a novel system programming language enforcing type safety at compile-time, and takes advantage of Rust's strong safety features. However, since Tock allows user-level applications to be written in any...

Traffic congestion at signalized intersections is a big economical and ecological problem. Handcrafted traffic light controllers (TLCs) are currently used to minimize the impact, but they are expensive to design and maintain and their performance degrades over time. Predictive TLCs and advanced driver assistance systems (ADAS) form a potential...

The use of Light Emitting Diodes (LED) as a main source of illumination<br/>can help in significantly reducing global energy conspumtions. The LED is<br/>well suited for modulating visible light, enabling a wireless communication<br/>channel. A popular topic in Visible Light Communication (VLC) research<br/>is to push data throughput past the...

With the arrival of smart electricity meters energy consumption can be monitored continuously and displayed on external devices such as phones or tablets. As a consequence, users become more aware of their energy usage which may result in a reduction in energy consumption. Nevertheless, many countries in Europe still use an analog electricity...
