A large range of products are now designed based on the implementation of microcontrollers, as they lead to an overall system enhancement, such as a more compact system design and reduced costs. This can be credited to the peripheral functions embodied in the microcontroller and the flexibility offered by its software. Since the applications of microcontrollers are achieved through software, the implementation of the target controller is considered as an interdisciplinary process. Due to the capability of the current development tool, designers are required to input significant effort such that the development with the process is taking a long time to complete. The purpose of this research is aimed at improving the current microcontroller software development process.

In this thesis, an 8-bit microcontroller, 8051 core, is implemented using SystemC
programming language. SystemC is a new generation co-design language which is
capable of both programming software and describing hardware parts of a
complete system. The benefit of this design environment appears while developing
a System-on-Chip (SoC), that is a system consisting both custom hardware parts
and embedded software parts. SystemC is not a completely new language, but
based on C++ with some additional class libraries and extensions to handle
hardware related concepts such as signals, multi-valued logic, clock and delay
elements. 8051 is an 8 bit microcontroller which is widely used in industry for many
years. The 8051 core is still being used as the main controller in today&rsquos highly complex chips, such as communication and bus controllers. During the development cycles of a System-on-Chip, instead of using separate design environments for hardware and software parts, the usage of a unified co-design environment provides a better design and simulation methodology which also decreases the number of iterations at hardware software integration. In this work, an 8-bit 8051 microcontroller core and external memory modules are developed using SystemC that can be re-used in future designs to achieve more complex System-on-Chip&rsquo
s. During the development of the 8051 core, simulation results are analyzed at each step to verify the design from the very beginning of the work, which makes the design processes more structured and controlled and faster as a result.

Increasingly System-On-A-Chip platforms which incorporate both micropro- cessors and re-programmable logic are being utilized across several fields ranging from the automotive industry to network infrastructure. Unfortunately, the de- velopment tools accompanying these products leave much to be desired, requiring knowledge of both traditional embedded systems languages like C and hardware description languages like Verilog. We propose to bridge this gap with Twill, a truly automatic hybrid compiler that can take advantage of the parallelism inherent in these platforms. Twill can extract long-running threads from single threaded C code and distribute these threads across the hardware and software domains to more fully utilize the asymmetric characteristics between processors and the embedded reconfigurable logic fabric. We show that Twill provides a sig- nificant performance increase on the CHStone benchmarks with an average 1.63 times increase over the pure hardware approach and an increase of 22.2 times on average over the pure software approach while reducing the area required by the reconfigurable logic by on average 1.73 times compared to the pure hardware approach.

In many processes it is important to have automatic control in the modern life. For example, PLC systems are using for machine control, water pressure and flow are able to be controlled by DDC program, even a car can be driven by computer. In this article, author will turn our focus on the control system for fermentation tank. The fermentation tank that produces methane is considered as clean and recycle energy source. It is widely used in house, electronic power machine and vehicle around the world. However, its reaction temperature and output concentration control are usually hard to detect without automation system. In this study, the problem is focused to combine fermentation tank and automatic control system in laboratory testing. In this paper, author will be able to use PIC (Peripheral Interface Controller) microcontroller to solve this problem and automatically control the methane tank output methane gas with certain concentration, which could be used as energy source. The temperature and concentration sensors that are chosen as input data of the controller and corresponding algorithm were performed on the PIC. They will be used to realize the composition and thermal state measurement. With those information, the valves of material and water control can be controlled in methane tank. Limited by the experiment equipment and methane reaction tank system, the controller was just tested in the laboratory environment instead of practical application. The test result shows that the controller has its capability to automatically control the stable output of methane gas. In the test, water and material valves are controlled automatically open or close after monitoring temperature and concentration information of the gas in the tank.

Microcontrollers - low-power, real-mode CPUS - drive digital electronics all over the world, making their safety and reliability critical. However, microcontrollers generally lack the memory protection common in desktop processors, so memory safety must come through other means. One such mechanism is Bedrock, a library for the Coq proof assistant that applies separation logic to a small c-like language, allowing programmers to prove memory-related properties about their code. I used Bedrock to build a security peripheral out of a Cortex-m3 microcontroller; my peripheral provides both AES encryption and append-only logging to a host system, and I showed the software it runs is memory-safe. Working with Bedrock was challenging but rewarding, and it provides a glimpse into a future where system programmers can prove code correct as a matter of course.

Jarle Kotsbak started started the company Kotsbak Consulting to test an idea he had of a method of sequencing DNA material, that is reading the contents of the string of genes in a DNA. The method is supposed to be much faster and cheaper than the methods that exist today. For the analysis equipment there are a lot of parts that need to be developed, and the most important ones in the first phases of experimentation is given as problems for this thesis.The analysis is going to take place in a relatively small reaction chamber where chemicals need to be automatically added and heated to the correct temperature. Then a high resolution image is going to be captured using a small image chip similar to those found inside digital cameras. As these have varying real time requirements, it is not possible to control from a ordinary PC. A microcontroller is needed to do the low level controls. Control of the experiments should be possible to set up from a PC connected to the equipment using a USB (Universal Serial Port) 2.0 port, which is also going to transfer the images captured to the PC for image and data analysis.Atmel AVR32 microcontroller was suggested for use, and it was not found that any of the requirements was not in theory possible to solve using this microcontroller, so it was the one used in all parts. It was evaluated if it was best to program the microcontroller directly without an operating system, but it was found that using Linux, which the evaluation boards of the microcontroller was shipped with, had so many advantages over the small and uncertain advantages of programming the microcontroller directly. so Linux was used in all parts. As most of the needed drivers for Linux were new or unreleased, a lot of time was spent learning how to compile the Linux kernel with those patches and finding out how to use the undocumented parts of the drivers, as well as extending the drivers to support the hardware and specification needed.The heating controller worked quite well after getting the connection to the sensors working, including estimation of the temperature inside the reaction chamber, which is the temperature that is going to be controlled, but can not be measured directly. If needed it is possible to tune the controller better for stricter requirements or change to a model based controller if needed and the parameters in the model can be found, which turned out to be hard.A nice solution to the flow control was found using a stepping motor that is able to push the piston in a syringe containing one of the chemical mixes in exact amounts, controlled by an external stepping motor driver chip, which was easy to get working, connected using I2C. The solution was at least as good and much easier to implement than the one suggested in the assignment, using valves and pressure measurements to estimate the amount flowing.It was shown that image capture of the required resolution, i.e. 2048 x 1536 and possibility for much higher, was possible using Linux and the hardware support for transferring images from image chips in the AVR32 microcontroller using kernel modules. The problem is that it was only working sometimes, so a little more debugging of the possible hardware/ software reason for this to be resolved, but it seems like it is only a small problem and not caused by any limitation in software or hardware.It was attempted to get the USB part working without running an O/S on the microcontroller, but it did not succeed, partly because of incomplete documentation of the USB hardware module in the AVR32. Then the available driver systems for USB slave equipment under Linux was studied and it was found that gadgetfs seemed most promising to use. The driver did though first not load, just giving a stacktrace. In a newer version of the Linux version for the development board, it did though load and it seemed like it was working. Further development of this part was not done because of much delay in the other parts, and the fact that choosing Linux as platform, as well as the image being buffered in RAM, allows to use ethernet to transport the images during testing until later product development stages.Overall most of the parts have been accomplished according to the specifications, although there was not too detailed practical testing of each part because of much time spent on solving problems, and the fact that many complex parts were outlined to be solved during the project. Solving the small problems left as described at the corresponding discussion chapters should, with small modifications/customization, make the practical solutions found usable for future prototypes of the product or for more experiments.

Microwave drying is an energy-efficient drying method. The output power of most commercial microwave ovens is controlled in an intermittent fashion, where the amount of microwave energy is determined by the ratio of "ON cycles" to "OFF cycles." To provide a more efficient and continuous power control for the magnetron, a microcontroller-based, feedback power control system was developed. The system was based on a phase-control principle to achieve smooth power variations depending on a feedback temperature signal of processed products. Two temperature sensors, a thermocouple and an infrared sensor, were used to measure the temperature. A fiber-optic thermometer was used for calibration and evaluation of the system performance during microwave drying. With the IR sensor, the mean standard deviation and maximum error in temperature measurement of controlled water samples were +/-0.34ºC and +/-1.5ºC, respectively. This result demonstrated the accuracy of the IR sensor in the system control. Under the IR sensor-controlled system, carrot cubes (Daucus carota L.) lost 85.37% of their water content and resulted in better color quality than the conventional microwave-hot air convective drying without a temperature feedback control.

An ad-hoc data acquisition system was constructed in order to control an array of different types of sensors and to collect their data. The system will be used as the core for electronic nose and tongue systems used for classifying and distinguishing different levels of contamination in water and other types of liquid. The system consists of analog and digital electronics as well as software for a microcontroller and a PC. The heart of the system is a PIC microcontroller that can communicate with the real world and with a PC. With the real world it is referred to analogue devices that measure things that are infinitely variable, they are not quantized like in the digital world which is an approximation of the real world. A microcontroller is a small computer fit into a single chip. This computer is a microprocessor together with memory and I/O ports. Microchip is a company that has produced popular microcontrollers called PIC’s. The microprocessor was programmed in the language C. The system can take samples at accurate time intervals. A LabVIEW program was developed so that the system can be controlled with a user friendly interface. The sensors can be monitored in the LabVIEW program and the data can be exported to a spread sheet text document, ready to be opened in another program for analysis. With serial transmission the designed data acquisition board cannot only be interfaced with LabVIEW on a PC running Windows, but also with Linux or Windows Mobile. The system is robust, economic and portable. The report tries to describe how the development was done.

The research presented in this thesis considers the feasibility of utilising dsPICs (digital signal controllers) in the development of effective monitoring systems which have the capability to adapt to changes in operating conditions and can be quickly calibrated to suit a range of applications, thus helping to reduce the development time constraint. The capability of these monitoring solutions to detect and isolate faults occurring in pneumatic processes is investigated and their effectiveness verified. Three applications are considered gas pipe leakage, linear actuator operations and gripper action. In each case, solutions are developed based upon the dsPIC. The solutions utilise the analysis of pressure transients to overcome the limitation in the dsPIC memory. The deployment of minimal sensors and electronics was essential to optimise the cost of the system. Leak detection techniques are developed with application to gas fitting pipes. The speed at which correct decisions are determined was the essence of this work. The solutions are tested, compared and their capability validated using pipes which had been rejected according to industrial standards. In this application a dsPIC digital signal controller and a pressure sensor were deployed, thus ensuring a low cost monitoring solution. Linear actuator "end of stroke" monitoring has, previously, largely been possible using limit switches. A more challenging method based upon the deployment of a pressure sensor is outlined. Monitoring model surfaces were obtained and their capability to determine the health of the process was proved, at various supply pressures. With regard to the gripper monitoring, a performance surface by which the gripper action can be monitored is generated and embedded within the dsPIC. Various faults are simulated and their effect on the gripper performance investigated. Leakage and blockage are also investigated at various places in the pneumatic circuit to allow for an algorithm to be devised. Faults may be detected and isolated, and their locations identified to allow for timely recovery treatment, thus supporting an enhanced process monitoring strategy.

This paper describes the development of an experiment to test the characteristics and functionality of Silicon Carbide (SiC) components in a space environment. The experiment is a part the "Miniature Student Satellite" (MIST) project, and the "Work on Venus" project, both situated at KTH, Stockholm, Sweden The paper primarily covers the development and implementation of the experiments microcontroller and its software, whilst the construction and development of the test circuit for the transistors is carried out at the same time by another team, and therefore described in a separate paper. A microcontroller is selected for this experiment after consideration is taken to both the Low Earth Orbit environment where the experiment will take place, end the power consumption restrictions due to the limited amount of power available at the satellite itself. The software on the microcontroller is then developed to read temperature and voltage input from the different transistors under test, and transform the input data to a readable format sent to the satellites On Board Computer, which can then communicate the readings to the Earth Base Station. Apart from the software of the SiC experiment, a similar software solution on a similar microcontroller is developed for another experiment called MOREBAC, which will be placed on the same satellite. The main difference between the MOREBAC project and SiC in Space will be the type of data read on the input, the number of inputs and the format of the package sent to the On Board Computer. The final stage of the work for this thesis is the design and construction of a Printed Circuit Board. The board contains the microcontroller and connected components, the transistors to be tested, as well as power supplying components, covered in yet another thesis work.Den här rapporten beskriver utvecklingen av ett experiment vars uppgift är att testa karaktäristiken och funktionaliteten hos Kiselkarbid(SiC)-komponenter i rymden. Experimentet, som går under namnet SiC in Space, är en del av "Minitature Student Satellite"-projektet (MIST), samt projektet "Working on Venus", vilka båda utförs på KTH, Stockholm, Sverige. Rapporten avhandlar huvudsakligen utvecklingen och implementationen av experimentets mikrokontroller samt den tillhörande mjukvaran, samtidigt som testkretsen för den transistor som undersökts utvecklades i ett annat projekt, och är således avhandlat i en annan rapport. En mikrokontroller valdes ut för projektet baserat både klimatet i "Low Earth Orbit" där satelliten kommer att befinna sig, samt de krav som ställdes på strömförbrukningen baserat på den begränsade strömförsörjningen på själva satelliten. Mjukvaran på mikrokontrollern utvecklades sedan för att avläsa temperaturvärden och spänningsnivåer vid testpunkter på transistorerna, för att sedan översätta denna data till ett läsbart format samt skicka den till satellitens omborddator, som i sin tur kan skicka datan till basstationen på jorden. Utöver den mjukvara som utvecklats till SiC in Space, utvecklades även en liknande lösning för ett annat experiment på satelliten, kallat MOREBAC. Den huvudsakliga skillnaden mellan de två mjukvarulösningarna är att de testpunkter som ska läsas av på MOREBAC skiljer sig både i antal och i utförande från de testpunkter som ska läsas på SiC in Space, samt det datapaket som sedan skickas till omborddatorn. Det slutgiltiga steget under detta projekt var sedan att designa och konstruera ett kretskort (PCB). Kretskortet innehåller både den mikrokontroller som avhandlas i denna rapport, transistorerna som ska testas, samt en strömförsörjningslösning som utvecklats i ytterligare ett parallellt projekt.

A Laser Music System has been created, that combines a laser and light sensor system with an infrared distance sensing system that detects the position of a user’s hand when it intersects one or more of the individual laser beam. The laser beams, which are made visible by a small amount of smoke in a dark room, provide visual guidance to the user to reduce the difficulty of using a non-contact instrument as well as enhancing an appealing optical effect for the user. The system uses a number of Sharp distance sensors to map the position of the user’s hand to a variable like pitch. The user should move their hand to different heights to achieve a desired pitch. The laser beam should be broken to trigger the desired note.

Alzheimer's disease and other forms of dementia cause cognitive disabilities in the afflicted person. As a result, the person with dementia often requires assistance from a primary caregiver. However, while the caregiver is away from the home they are unaware of the person's status and may not be able to find out without returning to the home due to dementia's effects on cognition.
In this thesis work, a system of embedded devices is presented which tracks a solitary dementia patient in the home in real-time. The system is composed of three main hardware components. Multiple passive and active sensors are strategically placed to monitor the patient. A number of custom battery-powered embedded systems read the sensors and wirelessly transmit the sensor's values. A central computational node collects the wireless transmissions and analyzes the data. Two algorithms were developed that detect the patient's eating activities and location throughout the home from the sensor data. A web-based user interface was designed that allows a primary caregiver to remotely view the patient's status while away from the home.
Numerous trials are performed which test the system's ability to monitor the patient's eating activities and location. The positive results of the trials show that the proposed system is able to detect eating patterns as defined by rules and localize in real-time the patient in the home, accurate to a single quadrant of a room.
The proposed embedded system is highly affordable and has two novel features, namely eating detection and patient localization accurate to a single quadrant of any room in the home. Both features use sensors installed in the home and do not require the patient to wear any sensors on their person. The state-of-the-art products currently available are able to localize only to a single room without the patient wearing sensors.

The Direct Methanol Fuel Cell (DMFC) has been considered as one of the competitive alternatives for battery technology as it has much higher energy density, faster recharging and does not require complicated control systems like a fuel reformer or compressed gas tank as needed by a hydrogen fuel cell. However, current DMFC technology suffers from the low power density caused by low reaction rate and undesired “methanol crossover” issues, which brings a big challenge for its application in practical systems.
This thesis presents a practical design and prototype development of a DMFC/battery hybrid energy management system, which can be provided as one possible solution for the low power and cold start issues. First of all the existing fuel cell hybrid system schemes and design of the auxiliary units (BOP) are surveyed and compared. Based on the analysis above a microcontroller-based DMFC and Lithium Polymer Battery hybrid system is proposed.
After that a novel “Battery-Current-Based Hybrid Control (BCBHC)” is proposed to provide active load sharing and proper battery charging and protection. The DMFC will follow the average battery current by neglecting the battery current transients and charge the battery by following the Constant-Current and Constant Voltage charging scheme when possible. A variety of battery protections, such as overcharging, overcurrent and charging current limitation, are implemented by the BCBHC and protection circuit.
A detailed system design and modeling are then presented. The models are developed and simulated in PSIM. The simulation results are analyzed and showed the validity of proposed hybrid control.
At the end a prototype hybrid EMS controller board has been implemented to further validate the hybrid system design. The dynamic behavior of DMFC/Battery hybrid system is examined and tested under a series of load experiments.

Parkinson’s disease is associated with reduced coordination between respiration and locomotion. For the neurological rehabilitation research, it requires a long-time monitoring system, which enables the online analysis of the patient’s vegetative locomotor coordination. In this work a real time step detector using three-dimensional accelerometer signal for the patients with Parkinson‘s disease is developed. This step detector is a complement for a recently developed system included of intelligent, wirelessly communicating sensors. The system helps to focus on the scientific questions whether this coordination may serve as a measure for the rehabilitation progress of PD patients.+46-762453110 +46-462886970

Spacecraft avionics initially commanded the development of the microprocessor industry, enabling microprocessors to be designed specifically for the reliability demands posed by the radiation environment of space. However, microprocessor have shifted their focus from ensuring reliable operations to maximizing performance, forcing the price of spacecraft avionics to balloon. Costing over three orders of magnitude more than current state of the art general purpose processors, while performing operations an order of magnitude slower. These differences stem from the reliability requirements of operating in space, typically achieved through hardware-based modifications. While these solutions generate the necessary reliability, they limit the engineering options for the system and force the use of outdated technology. A solution researched but never widely implemented, is the use of error detection and correction software algorithms. An ideal design lies in the combination of hardware and software methods for providing reliability. A new avionics architecture was designed to implement a system using hardware and software to achieve reliability with COTS products. The architecture was applied to the CASTOR satellite as its primary avionics system, for verification testing of the architecture's functionality. This architecture further aims to expand spacecraft usage of microcontrollers as the primary spacecraft avionics computers.

Este trabalho propõe a geração de uma arquitetura dedicada a aplicações específicas, baseadas no microcontrolador MCS8051. Por ser utilizado na solução de problemas em indústrias locais, este processador foi escolhido para servir como base em um sistema dedicado. O 8051 dedicado gerado deverá permitir a integração completa do sistema, proporcionando um aumento do valor agregado e, conseqüentemente, a diminuição do custo. Busca-se com a otimização da arquitetura obter um conjunto de instruções reduzido, construído com as instruções mais utilizadas em cada aplicação. O objetivo principal da otimização do conjunto de instruções está relacionado ao fato de que os circuitos decodificadores e geradores de microcódigo da parte de controle ocupam uma área significativa do processador. Uma otimização no sentido de reduzir-se o conjunto de instruções, portanto, resulta numa economia de área, o que vem de encontro com a idéia da integração completa do sistema com o processador. Um processador dedicado a aplicações específicas (ASIP) irá possuir um custo maior do que a sua versão original, devido as otimizações realizadas. Para compensar este custo, uma alternativa a seguir é a integração completa do sistema. Um Sistema Integrado para Aplicações Específicas (SIAE) torna-se desejável, pois aumentando o valor agregado do circuito possibilita-se a redução do custo pela eliminação de conexões da placa, do encapsulamento de outros circuitos, entre outros motivos. Todavia, para que um SIAE possa ser construído com um custo aceitável, é necessário que seja construído em uma área que não exceda muito a área original do processador. Tenta-se fazer isto neste trabalho, através da implementação de aplicações com poucas instruções diferentes. Por ser uma arquitetura comercial, o 8051 possui um grande parque de software desenvolvido e resolvendo problemas. Isto pode ser considerado uma vantagem pois, software básicos como por exemplo, compiladores, já estão desenvolvidos. Outra vantagem é o grande número de engenheiros treinados na sua utilização. Desse modo, torna-se necessária a criação de uma compatibilidade de software, para preservar o que já está desenvolvido. Uma vez que a programação em nível de linguagem montadora tende a constituir-se em uma tarefa cansativa e sujeita a erros, é desejável que se tenha uma compatibilidade em alto nível, ou seja, através de um compilador. Para criar a compatibilidade de SW necessária é realizada a otimização de um compilador C desenvolvido para o 8051. A escolha pela linguagem C deve-se ao fato de sua grande utilização. O compilador C otimizado procura utilizar um conjunto de instruções reduzido para obter a economia de área. Quando uma instrução necessita ser utilizada e não está presente no conjunto de instruções desejado, o compilador tenta substituí-la por outra(s). Um conjunto de instruções é utilizado para cada aplicação, sendo constituído pelas instruções mais utilizadas por esta. Para determinar as instruções mais utilizadas de cada aplicação é realizada uma análise estática sobre um código em linguagem montadora previamente compilado. As instruções implementadas serão sempre parte do conjunto de instruções original do 8051, de modo que novas instruções não serão criadas.Um programa em linguagem montadora gerado com um conjunto de instruções reduzido (RISC) normalmente terá um número maior de instruções do que o seu 10 equivalente com o conjunto de instruções completo (CISC). Isto ocorre porque possivelmente algumas substituições de uma instrução por outras, terão que ser realizadas. Como as instruções que serão utilizadas nas substituições pertencem ao conjunto de instruções original, o programa gerado com o compilador otimizado poderá executar em um tempo maior do que se fosse compilado com o código CISC. Para compensar esse atraso foi implementado um pipeline de instruções para o 8051. Este trabalho apresenta resultados da Síntese Lógica em Standard Cell e FPGA da arquitetura otimizada. Além disso, resultados de programas em linguagem montadora gerados com o compilador otimizado, são também apresentados.This work discusses a processor for specific applications architecture, based on the MCS8051 microcontroller. This processor is used as a solution for many local industry applications, being the base of dedicated systems. The dedicated 8051 generated should allow complete integration of the system, and with the added value to the chip, reduced costs. The architecture optimization will produce as result a reduced instruction set, made by the often used instructions for each application. The main instruction set optimization goal refers to the instrucions decoders and microcode generators in the control part, because a large area in the processor is needed to implement them. Thus, a reduced instruction set will allow area savings, making possible the complete system integration in a chip. An ASIP architecture will have a higher cost than the original one. An alternative to solve this problem is add value to the chip, creating an Application Specific Integrated System (ASIS). An ASIS can be made with a acceptable cost, if it’s possible to integrate other circuits to the chip without area increase. This can be done in the area saved by using fewer implemented instructions. Because the 8051 is a commercial architecture, there is a large amount of software developed for it. This can be considered an advantage because basic softwares like compilers are available, being not necessary to create them. Another advantage refers to the large number of engineers trained to use the 8051. To preserve the already developed applications it’s necessary to mantain software compatibility. Assembler level programming is very boring an error prone task, being desirable to have software compatibility at higher levels through the use of high level languages. To create the necessary SW compatibility, a C compiler developed for 8051 was optimized. The chose for C language refers to its large utilization. The optimized C compiler tries to use a reduced instruction set, formed with the most important instructions for each application, in order ro save area. When an instruction needs to be used in an application, and it’s not present in the instruction set, the compiler tries to replace it with other instructions. The compiler will not use instructions not present in the original 8051 instruction set. So, new instrucions will be not created. To create an instruction set formed with the most important instructions for each application, a static analysis is made on a precompiled assembler source. An assembler source generated with a reduced instruction set (RISC) will probably have more instructions than the same assembler generated with a full instruction set (CISC). This can be explained because of the replacements instruction. If one instruction is replaced by other two, and these are from the original instruction set, probably the time needed to execute them would be higher. In order to deal with this problem, an instruction pipeline was implemented to the 8051. This work presents Standard Cells and FPGA results of Logic Synthesis of the optimized architecture. Also, assembly programs generated by the optimized compiler are presented.

This thesis project was carried out at Volvo Car Corporation. It is based on an EU project called Locust in which a bio-inspired visual sensor system (the Locust sensor system) for automotive collision avoidance was developed. The Locust sensor system is designed to emulate the collision avoidance functionality of the Locust grasshopper, which is well-known for its extraordinary vision based collision avoidance ability, in particular with regard to its fast reaction times to perceived threats. Volvo Car Corporation is interested in the possibility of using the bio-inspired technology developed in the Locust project to improve its already existing collision avoidance systems. Pedestrian collision avoidance is of high interest, for which the properties of the Locust grasshopper are desirable.
The purpose of this thesis project is to develop two demonstrator vehicles to test the performance of the Locust sensor system, carry out the testing, and evaluate its usability for Volvo Car Corporation. The first vehicle is a scale 1:5 model car that was originally developed in a thesis project at KTH, and the second a full scale Volvo XC90.
It was found in the testing that the Locust sensor system is promising for pedestrian collision avoidance applications. The results for detecting other vehicles were also acceptable, but Volvo Car Corporation already has other collision avoidance systems with better performance in this regard. In general the test results were very good for speeds up to about 40 km/h. This indicates that the Locust sensor system would be most usable in a city driving environment, parking lot situations, and for driving in residential areas.

Повний текст джерелаАнотація:
Capillary electrophoresis laser-induced fluorescence (CE-LIF) is widely used to detect both the presence and concentration of fluorescently labeled biomolecules. In CE-LIF, a plug of sample fluid is electrophoretically driven down a microchannel using a high voltage applied between the opposite ends of the microchannel. Molecules of different sizes and charge states travel at different velocities down the channel. Laser light with a wavelength in the excitation band of the fluorophores is focused near the end of the channel. As each species of molecule passes through the laser spot, the fluorophores emit a fluorescence signal which is measured with an optical detector. Commercial CE-LIF systems are available as a complete, expensive package. Custom CE-LIF systems are a collection of commercially available components that meet the specific needs of the end user. Using the custom system in Dr. Woolley's lab as the standard, we hypothesized that 3D printed parts in conjunction with low-cost components could be used to significantly reduce costs and simplify the system, which in turn would make such systems more widely available with a lower barrier to entry. Testing this hypothesis began with five semesters of small teams of senior undergraduate students trying to design and assemble a low-cost CE-LIF system as part of their mandatory one-semester senior project. I was one of the seniors who worked on the system. Although none of the senior project teams were successful, a partially functioning system was ultimately produced. I reference this system as the starting point system throughout this thesis, which is focused on identifying and solving the system's obstacles in order to reach a working state. I re-designed and re-built each sub-system of the starting point system as needed if within the available budget to create a system that was functional. Budgetary constraints were included in evaluating potential improvements. The end goal was to compare the improved system's performance with that of an expensive conventional system (hereinafter referred to as the standard system) available in Dr. Adam Woolley's laboratory on the Brigham Young University campus. The ultimate conclusion of my masters' thesis work is that a low-cost CE-LIF system based on 3D printed and low-cost components results in a system that does not offer repeatable performance. In the course of my work, many lessons were learned as to what would reduce overall system costs while maintaining a user-friendly experience. My analysis is given on a subsystem basis to explain what limited the ability of the system to run consistently or what caused it to fail altogether. Details and methodology of my contributions including circuits designed, code written, components used, and 3D models printed in order to test the hypothesis are documented. Attribution of the work prior to mine is laid out when each subsystem is broken down in detail for the failure modes that prevented consistent operation. Future work is suggested to correct the problems encountered and provide a path forward to implement a next-generation system that can be achieved at a lower cost compared to a conventional system, and yet which does not suffer from the performance problems associated with the version explored in this thesis in which maximum cost reduction was aggressively pursued.

In recent years, the applications of multimedia have widely appeared in ourdaily lives, for instance, GPS navigation systems, cellar phones and electronicbooks. You can easily spot multimedia applications everywhere. The purpose of this study was to gain an understanding of the design of embedded hardware-software systems based on commonly-used ARM microcontrollers and through the application of multimedia. In terms of hardware, pulse-width modulation (PWM) was employed to replace digital-to-analog converter (DAC) output. For software, an underlying SD card process was developed and integrated with the FAT file system, which enables rapid file storage when developing an embedded system. The encoding and decoding process of pulse-code modulation (PCM) is used in playing WAVE music files. In addition, by playing MP3 music files we can understand the encoding and decoding process of music compression.

Bioelectrical impedance analysis is based on that the different tissues have different characteristics to obtain the relevant biological information. It has been wildly used to detect much biological information for decades. No matter what kind of application, their measurement hardware and algorithm are very important. Traditional LCR meters are certainly accurate, however its size, and power consumption will make it difficult for portable applications. Furthermore, previous impedance measurement can not distinguish a very small amount of the phase change, leading to considerable deviation from the actual value. This study develop a low-frequency, high-accuracy impedance measurement platform. The system utilized a microcontroller, MSP430, as the core unit. It was compared with a LCR Meter to determine the accuracy and reliability. The resulting system is a portable, low-cost, automatic and real-time display device for the convenience of the impedance measurement.

The needs of home health care systems are getting stronger day by day in the aging population. This research used a device called ‘Vital-Belt’ designed by Dr. Chih-Cheng Lu, NHRI. The device acquires two bio-signals in real-time: ECG and signals from 3-axis accelerometer for detecting falling. We added a very low power microcontroller MSP430 into this device to process these bio-signals. Motion artifact is the most critical problem in the ambulatory ECG. In this research, we emphasized the processing of the ECG disturbed by motion artifact. A dynamic threshold was determined by calculating the activity levels from accelerometer. We used this method to detect heart rate and abnormal beats in real-time and transmitted abnormal ECG to a computer or PDA via Bluetooth. From five healthy persons, the averaged accuracy of R-peak detection was 99.85%, 99.26% and 99.16% in standing, walking (4 miles/hr) and slow running (6 miles/hr) situations, respectively. The averaged detection error rate was 1.45%, 1.84% and 1.89%, respectively. The experiments were performed in a treadmill. For atrial premature contraction (APC) and ventricular premature contraction (VPC) detection, test four MIT/BIH data sets (105, 116, 118, and 119) were used. The averaged accuracy of R-peak detection was 99.89%. The averaged accuracy of APC and VPC detection was 93.81%.

Augmentative and alternative communication(AAC）are connected with the help of the persons with disabilities mainly in speech. AAC includes body language, picture communication board, blissymbols, and other communication aids in which speech is most efficiently used in all modes of communication. The integration of the technology in recording and playing of voice with the automatic performance of single-chip microcomputer (microcontroller) makes the augmentative & alternative communication system more powerful than ever. In the system developed here the speech can be recorded in the long-term and erasable memory area. Within the total recording duration of 60 seconds, 30 speech sections are divided into four pages: 2, 4, 8, 16 sections are given in the pages 1, 2, 3, 4 respectively. It also provides the external switches for the persons whom the built-in switch can not be reached. We hope that the modern scientific technics can put AAC forward a big step with the great help of the persons with disabilities.

The objective of this dissertation is to carry out a bio-medical monitoring system based on the embedded System-on-a-Chip(SoC) tech. We design two systems, which are the simple ECG signal record system and complex pulse signal measurement system. Both systems are developed by Programmable SoC Microcontraller(PSoC),and discuss the advantages and faults between them. In this study, they can provide a standard industrial interface RS232 to real-time measure bio-signal and display in PC . In order to identity the performance of both systems, We test and verify separately for each function of the model for PSoC. The results showed that it meets our specification of systems. It is proved by the embedded SoC tech, the occupied area can be minimized, and the expense of the system can be reduced. Therefore, this way is convenient to use.

In this research, we developed a hardware circuit of an active battery management system for lithium iron phosphate (LiFePO4) rechargeable batteries that are connected in series. The primary circuit is based on a flyback DC-DC converter with an isolated DC step-down design, while the secondary circuit includes a dedicated charging subsystem with an appropriate micro control unit for intelligent charging management. Since the lithium battery charging time of each battery cell voltage with respect to the discharge time of each battery cell voltage variation is more obvious, so the introduction of voltage balancing mechanism in the charging process to narrow the difference in voltage between the battery cell, the same, with improved fly-back DC step-down design to prevent excessive charge of the battery cell.

This paper describes an automatic microcontroller design system, which can produce the most simplified microcontroller-architecture according to application program, and reduce the designing time caused by artificial oversight at the same time. Moreover, automatic microcontroller design system can cut down the cost of research and design. In the beginning, the microcontroller-architecture based on ADL (Architecture Description Language) and CBDL (Component Behavior Description Language) are described. Then, the ADL and CBDL will be translated RTL Verilog code based on a translator, which is developed in this thesis. The RTL Verilog code of an 8-bit RISC microcontroller will be verified and implemented by a FPGA and ASIC. Due to the incompletion of definition of ADL and CBDL, moduling microcontroller design system based on Verilog will be proposed. This method can reduce the developed the difficult of translator. The moduling microcontroller design system produces the most simplified microcontroller-architecture implemented by RTL Verilog which can be adapted the application specific program. Then, it can be easy to proceed to the design flow of ASIC Cell-Based.

The Internet of Things (IoT) gateway serves as a key intermediary between a considerable amount of smart things and their corresponding cloud networking servers. Academics and industry members have invested substantial research and development resources into developing IoT gateway-related technology and products. In small and low-power IoT applications, conventional gateway systems mainly use microcontrollers to perform lower-layer device network management, upper-level cloud server functions, and remote mobile computation services. However, regarding system scalability and computation and communication efficiency, solutions that use a single microcontroller cannot cater to the demands of IoT regarding large data collection, management, communication networks, and various other services. Therefore, this study proposed an innovative multimicrocontroller system framework, combining a field-programmable gate array-based hardware bridge and scalable multiple microcontrollers to construct a master–slave architecture of a high-performance multimicrocontroller IoT gateway. The proposed system features distributed processing, high-speed communication among microcontrollers, and compatibility with a wide variety of peripheral devices. In the end of this study, we implement an IoT application system case to verify our multimicrocontroller IoT gateway which has obviously more performance advantages than before.

This research investigates the improvement on hardware and communication for traditional UAV formation flight. The major tasks include the redesign of a multi-microcontroller system and a Sequential Cyclic Broadcast Communication (SCBC) mechanism. The multi-microcontroller system allows the implementation of a distributed computation architecture for improving the computational capability and flexibility for varies applications. Based on the SCBC structure, an identification algorithm using prime factorization techniques is developed to ensure the transmission security of the transmitted flight information. The proposed algorithm is successfully verified using a random numerical simulation.

In this research, we adopt Arduino's ATmega328 chip, Bluetooth communication technology and Android APP to design remote monitoring automation systems. Remote monitoring is a very basic and important technology for the modern industry. We collect the required physical information from the sensors and analog to digital converter, and program the microcontroller to automatically identify the received data and make responses with a pre-described sequence such as a general programmable logic controller (PLC) does. And APP which is developed for Android system is used as the human machine interface (HMI) to communicate with the Arduino chip. The user can easily have the information about the controlled system through the APP, and make decision by manual or automatically to activate the associated functions to make the system work followed the desired. The designed two systems are: (1) a low-cost air quality remote monitoring and control system used indoors. The system is applied to prevent form the harmful smoke which comes from the traditional religion of burning incense, the system can be used to automatically filter out the smoke by acting the ventilation system. (2) A fully automatic automotive air conditioner cleaning system, which was originally designed by programmable logic controller (PLC) and human-machine interface (HMI) made by touch panel. The functions which are originally controlled by PLC are substituted by Arduino, and APP is designed to communicate with Arduino as the HMI in PLC-based system. The prototype system is tested to be able to as an alternative for a sequential controller.
