The goal of this thesis is to design and create the working place with performance validation measure.

Development today has moved more towards battery technology, partly due to the increased demand of electric vehicles (EVs). The quest for a sustainable society is at an all-time high, with electrification of almost all devices only being the beginning. Due to the use of the fragile Lithium-Ion battery, a system that controls and monitors the battery must be implemented to ensure that it operates normally. A system like this is often referred to as a Battery Management System (BMS), in this case for Lithium-Ion batteries. The objective in this thesis is to construct a modular BMS playground for NEVS in Trollhättan to continue development on. The interface for the system will consist of Controller Area Network (CAN), a fast and robust communication protocol used in almost all personal vehicles today, and Isolated Serial Peripheral Interface (isoSPI), an isolated adaptation of one of the most common communication protocols used in sensors and microcontrollers so far. The BMS will be constructed of four individual subsystems using Arduino, each with a different purpose. These four subsystems are later merged into one BMS system to offer communication between CAN and isoSPI, thus supporting a future integration of this BMS to the Vehicle Control Unit of an EV. Moreover, since the BMS is going to be developed for a vehicle, modes for engaging the vehicle to drive and stop will be made. In order to provide some safety measures, automatic disconnection of the battery in case of an error will be added. The BMS with the previously mentioned features, also capable of doing voltage measurements with a safe connection/disconnection of the battery was then made. Features such as current and temperature monitoring were omitted due to time constraints and will in the future instead be done by NEVS along additional features. This thesis was conducted by Karlstad University and NEVS in Trollhättan, Sweden.

According to NHTSA Traffic Safety Facts [9], bicyclist deaths and injuries in 2013 are recorded as 732 and 48,000, respectively. In the State of Florida the safety of bicyclists is of particular concern as the bicycle fatality rates are nearly triple the national average. Further Florida ranks #1 on bicycle fatality rate in the nation for several years. To determine the cause of near-misses and crashes, a detailed study of bicyclist behavior and environmental conditions is needed. In a Florida Department of Transport (FDOT) funded project, USF CUTR has proposed naturalistic bicycle study based on ride data collected from 100 bicyclists for 3000 hrs. To this end, Bicycle Data Acquisition System (BDAS) is being researched and developed. The main objective of this thesis work is to design and implement low power video and audio subsystems of BDAS as specified by domain experts (USF CUTR researchers). This work also involves design of graphical user interface (Windows application) to visualize the data in a synchronized manner. Selection of appropriate hardware to capture and store data is critical as it should meet several criteria like low power consumption, low cost, and small form factor. Several Camera controllers were evaluated in terms of their performance and cost. The major challenges in this design are synchronization between collected data, storage of the video and sensor data, and design of low power embedded subsystems.

Home surveillance is a major concern in this day and age as with the rapid increase in the technology around us. There is a need to get updated with new possibilities to make our lives better and easy. Some cases and situations exhibit the need for home monitoring. So, we set out to discover a solution to this problem of home monitoring. Generally, we have issues with pets and kids alike such as approaching dangerous places like electric switches, stairs, and hot things. Not only a problem with kids and pets but also a chance of burglary and stranger's unusual activities. To overcome this problem we are designing and prototyping a system to keep an eye on kids, pets, and older people. This system is used in other applications like theft monitoring. The device can monitor the field all the time. In this way, this system helps in-home monitoring. The system consists of Arduino, which is the brain of the system, the PIR sensor, ESP32-CAM, and buzzer. The PIR sensor detects motion then gives input to the Arduino. Arduino gives output to the ESP32-CAM and buzzer. The ESP32-CAM can be activated and sends information to the user through the web Interface and the application. The user can see the video streaming on the PC screen or any other display. The buzzer can emit a high volume signal indicating that "there is an alert at the home".

The Emotiv Insight is a commercially available, low-cost, mobile EEG device that is commonly overshadowed by its costlier counterpart, the Emotiv EPOC. The purpose of this report is to investigate if the Emotiv Insight is a suitable headset to be used as a controlling factor in conjunction with an Arduino microcontroller and various electrical components that are used towards the development of an open-sourced, affordable electric wheelchair with the primary goal of providing those who either do not have the financial resources or the physical capability to operate a traditional wheelchair due to their disability a viable option to improve their quality of life. All of the C++ code, STL files used to fabricate the 3d-printed components are uploaded to a GitHub repository as open sourced files to allow individuals with access to a 3d-printer to either build the open sourced wheelchair for their personal use, or refine the design to suit their needs.

The aim of the work is the design and implementation of two circuit boards delivering learning platforms, which will consist of two separate circuit boards with ARM MCU and a programmable FPGA gate array that will be interconnectable and appropriately complemented by peripherals. These platforms will be developed by analysing current teaching and development platform solutions and then demonstrating on practical examples. The main benefit of this work should be update and simplification of existing equipment. At the same time, there is an emphasis on greater transparency of the whole solution, so that it is not too complicated for an aspiring student to familiarise himself with modern micro-controllers and programmable gate arrays and can link the simpler units into more complex ones, where the individual boards can be used as separate working units and their interconnection will provide a computationaly stronger yet more complex device.

The Swedish Defence Materiel Administration provides tests and evaluations of military Aircrafts and their systems as well as provide services in connection with military exercises. Testing aircraft against a radar antenna and training crews with this radar is part of that offering. The radar is deployed in a container rig and controlled by a computer running Windows 2000. The current option to control this computer is a mouse and keyboard. In this thesis, a system will be designed that is able to improve the ease of use of this rig while minimizing any need to modify the radar rig’s already established hardware and software. The resulting system designed used a commercially available joystick and off the shelf single board micro-controllers in combination with a graphical user interface to supply the radar rig with a converted input from the joystick in the form of mouse and keyboard commands, simplifying the end-user experience.
Försvarets materielverk tillhandahåller test och evaluering av militära flygsystem. De tillhandahåller även tjänster rörande militära övningar såsom belysning av flygplan med en radar för att öva piloter. Denna radar är monterad i en container och kontrolleras av en styrdator som kör operativsystemet Windows 2000. Denna dator styrs med hjälp av en mus och tangentbord. I denna rapport kommer ett system designas som kan förbättra användarupplevelsen av denna dator samtidigt som förändringar av hårdvara eller mjukvara i styrdatorn undviks. Resultatet av rapporten var ett system bestående av en kommersiellt tillgänglig joystick och två microkontrollers i kombination med ett grafiskt användargränssnitt som omvandlar knapptryck och styrutslag från joysticken till mus och tangentbords kommandon i styrdatorn.

The challenges faced by mathematics education reflect the more immense difficulties of the schooling system as a whole. This thesis investigates such challenges in the light of an ethical learning foundation and aims for a transformation through the use of technologies as learning tools.  Interaction design methods are used to craft constructivist learning kits that aim to move mathematics students from passive receivers of knowledge to active learners. The proposed tools modify new technologies by adapting them to teachers’ and learners’ needs to be best suited for mathematics classroom adoption. Additionally, social, political, and economic issues that may hinder the adoption of constructivist learning are presented and critically discussed.  Finally, this thesis paves the way for future designers who aim to design mathematics educational kits by providing a design framework based on the learning theory and the design process presented in this thesis.

Hospital environments are ranked as one of the most stressful contemporary work environments for their employees, and this especially concerns nurses (Nejati et al. 2016). One of the core problems comprises the notion that the current technology adopted in hospitals does not support the mobile nature of medical work and the complex work environment, in which people and information are distributed (Bardram 2003). The employment of inadequate technology and the strenuous access to information results in a decrease in efficiency regarding the fulfilment of medical tasks, and puts a strain on the attention of the medical personnel. This thesis proposes a solution to the aforementioned problems through the design of ambient displays, that inform the medical personnel with the health statuses of patients whilst requiring minimal allocation of attention. The ambient displays concede a hierarchy of information, where the most essential information encompasses an overview of patients’ vital signs. Data regarding the vital signs are measured by biometric sensors and are embodied by shape-changing interfaces, of which the ambient displays consist. User-authentication permits the medical personnel to access a deeper layer within the hierarchy of information, entailing clinical data such as patient EMRs, after gesture-based interaction with the ambient display. The additional clinical information is retrieved on the user’s PDA, and can subsequently be viewed in more detail, or modified at any place within the hospital.In this thesis, prototypes of shape-changing interfaces were designed and evaluated in a hospital environment. The evaluation was focused on the interaction design and user-experience of the shape-changing interface, the capabilities of the ambient displays to inform users through peripheral awareness, as well as the remote communication between patient and healthcare professional through biometric data. The evaluations indicated that the required attention allocated for the acquisition of information from the shape-changing interface was minimal. The interaction with the ambient display, as well as with the PDA when accessing additional clinical data, was deemed intuitive, yet comprised a short learning curve. Furthermore, the evaluations in situ pointed out that for optimised communication through the ambient displays, an overview of the health statuses of approximately eight patients should be displayed, and placed in the corridors of the hospital ward.

This thesis proposes to analyze and process the signals transmitted in real time, such as using the radar system to measure the distance , speed of object measurement, etc., and then use the human-machine interface (LabVIEW) to filter the signals and display them on the computer screen. Users can get their relevant data, which uses the Arduino's signal to perform preliminary analog-to-digital converster, and uses the relevant Bluetooth module to transfer to LabVIEW in the computer. The signals display in time domain and frequency domain to show different frequency. The signal that has been processed by the analog-to-digital converster is displayed with different frequency signals in the time domain and the frequency domain, respectively, and in this paper, the human life signs are used as the measurement target, because the human body will still produce the fluctuation of breathing and heartbeat even when it is at rest, and the measuring signal will transmitt the measurement signal through the Bluetooth of the Arduino. The wireless transmission method can reach and display at a certain distance with Bluetooth. Finally, the results of different materials and spectrum versus time are presented to prove the stability of the measurement capability and measurement capability of this design architecture.

With advances in technology, many appliances are equipped with remote controller. The remote controller is a handy device that allows us to easily control many home appliances. But because of this ,there are many kinds of remote controller at home. And because of each type of appliance remote controllers are different. It becomes an obsession in finding the remote controller. Thus, the universal remote controller was invented to solve these problems. Although traditional universal remote controllers solve problems of too many kinds and quantities of remote controllers. But the traditional universal remote controller often contains a lot of buttons for use for most brands of home appliances. This causes the interface of remote controller is too complex and difficult to use. And too many buttons also cause to press mistakenly or some buttons almost never used. Furthermore, the main material of universal remote controller is still plastics, so the environmental problems caused by using of plastic is not resolved, even larger amount. To solve above problems, this study integrates the Arduino platform, Bluetooth, Near Field Communication (NFC) technologies to build a Universal Infrared Remote Control Platform (UIRCP) base on smartphone and to design a brief definition of remote control codes in XML. In the framework of UIRCP, there are XML syntaxes for manufacturers to define remote control interface. Manufacturers will define the remote control interface and store the definition in NFC tags, after that tags will be sell with products. And consumers can use a single APP to get the remote control interface by scanning the NFC tag through smartphone after they purchase of these products. So it can achieve the purpose that store and switch remote control interface in single APP. In addition, smartphones do not have the function of transmitting infrared now. Therefore, this study increasing the Bluetooth module on the Arduino platform to receive infrared control codes from the smartphone, then send the remote control codes to appliances via infrared transmission modules. Compared to the traditional universal remote controller, this study using smartphone as a remote control device. Not only support the integration of multiple remote control interface onto a single APP, but also can simplify the control interface to avoid pressing the wrong button. For manufacturers, this study can help them to cost down by using NFC tags instant of remote controllers. iv But also reduce harm to the environment due to a significant reduction in the use of plastic material.

Relatório de estágio de mestrado em Ensino de Informática
O ensino de programação de hardware ou de protótipos no Ensino Secundário, não é uma tarefa fácil de concretizar, quer pelas dificuldades intrínsecas, levantadas pela programação de computadores, quer pela recetividade dos alunos, que a consideram uma tarefa fastidiosa. Sob este ponto de vista, a utilização de metodologias e de ferramentas que facilitem a abordagem das tarefas de programação são, em regra, bem recebidas no meio escolar. Foi com essa preocupação em vista que organizei o meu projeto de intervenção na escola, cuja experiência apresento neste relatório. O projeto foi implementado numa turma do 12.º ano do ensino profissional do Curso Profissional Técnico de Gestão de Equipamentos Informáticos do Sistema de Ensino Português, na disciplina de Instalação e Manutenção de Equipamentos Informáticos. Os trabalhos, desenvolvidos através da utilização combinada da placa Arduino com o software de programação visual Physical Etoys, consistiram em pequenos projetos pessoais, compreendendo projetos de controlo de componentes eletrónicos, tais como sensores de luminosidade, motores, botões de pressão, semáforos e automatismos associados ao controlo de tráfego, realizados por estudantes do 12.º ano do ensino profissional, com reduzidos conhecimentos de programação. No decurso do projeto foi possível observar que, ao contrário do que habitualmente ouvimos dizer, os estudantes entusiasmam-se com os conteúdos curriculares e envolvem-se empenhadamente nas aulas ditas de “programação”. Este relatório cobre as diversas fases do projeto de investigação associado ao estágio, incluindo as fases de observação, planeamento, implementação e monitorização, recolha e análise de dados, e as conclusões a que cheguei. Destaco também as metodologias de aprendizagem baseadas na resolução de problemas apoiadas por recursos tecnológicos com interfaces mais fáceis de utilizar e de compreender, de onde parece resultar uma melhoria do ambiente de aprendizagem e dos resultados obtidos pelos estudantes. Concluo ainda que a elevada aplicabilidade dos recursos experimentados em contexto de sala de aula fomenta a aquisição e o desenvolvimento de aprendizagens, o raciocínio lógico e o pensamento computacional, para além de potenciar a autonomia dos estudantes na utilização de componentes eletrónicos em protótipos e em projetos de sua iniciativa.
Teaching programming of hardware or prototypes in Secondary Education is not an easy task to accomplish, either due to the intrinsic difficulty, raised by computer programming, or the receptivity of the students, who consider it a tedious task. From this point of view, the use of tools and methodologies to facilitate the approach of programming tasks are generally well received at schools. It was with this in mind that I organized my intervention project in the school, whose experience I present in this report. The project was implemented in a class of the 12th grade of vocational education in the professional course of Management Computer Equipment of the Portuguese Teaching System, in the curricula of Installation and Maintenance Equipment Computers. The work, developed through the combined use of the Arduino board with the visual programming tool Physical Etoys, consisted in small personal projects, including projects for control of electronic components, such as light sensors, motors, pushbuttons, automatic lights and associated traffic control, performed by students in 12th grade of vocational education, with reduced programming knowledge. During the project it was possible to observe that, contrary to what it is usually heard, students were enthusiastic with the curriculum content and have engaged themselves, thoroughly, in lessons called "programming lessons". The report covers the various stages of my research associated with the project, including the phases of observation, planning, implementation and monitoring, collection and analysis of data, and the conclusions reached. I truly wish to emphasize the learning methodologies based on problem solving supported by technological resources with interfaces easier to use and understand, which seems to result in an improvement of the learning environment and the results obtained by the students. Finally, i conclude that the high applicability of resources experimented in the context of the classroom fosters the acquisition and development of learning, logical reasoning and computational thinking, in addition to promoting the autonomy of the students in the use of electronic components in prototypes and projects of their own initiative.

With the increasing ubiquity of networked “smart” devices that read and gather data on the physical world, the disembodied, cognitive realm of cyberspace has become “everted,” as such technologies migrate the communications networks and data collection of the Internet into the physical world. Popular open-source “maker” practices—most notably the practice of physical computing, which networks objects with digital environments using sensors and microcontrollers—increasingly push human-computer interaction (HCI) into the physical domain. Yet such practices, as political theorists and some philosophers of technology argue, bypass the very question of subjectivity, instead lauding the socioeconomic liberation of the individual afforded by open-source hardware practices. What is missing across these discourses is a technocultural framework for studying the material ways that everted technologies articulate subjects. I argue that examining the various, contradictory forms of interface that emerge from physical computing provides such a framework. To support this claim, I focus on several case studies, drawn from popular physical computing practices and communities, and analyze the particular ways that these devices articulate subjectivity. I conclude by linking my technocultural framework with various feminist theories of boundary transgression and hybridity, and end by suggesting that, in an everted landscape, the subject is politically constituted by a proximity to present time and space.
