Abstract:
För många med en inbrottscentral hemma eller på sitt företag  kan det vara intressant att i realtid kunna få information om statusförändringar. I vanliga fall kontaktas man av larmcentralen som man är ansluten till, men då oftast enbart vid allvarliga händelser som t.ex. larm eller sabotage och oftast med någon minuts fördröjning.I detta arbete visar jag hur man med enkla medel kan utöka funktionaliteten på sitt larmsystem genom att använda sig av en mikroprocessor och en mobiltelefon. Arbetet resulterar i en fungerande konceptuell enhet med förslag till enkla förändringar för utökad funktionalitet och säkerhet.

Abstract:
This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea’s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task. The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument. The commands will be translated by a microcontroller into the correct movement of the samples needed to load them. Most of the work was put down into developing the software responsible for handling communications and actuation of a couple of stepper motors. Lastly a circuit board was designed and manufactured, ready to be mounted into the existing instrument. The result was a working prototype which now is used in the daily work at Q-linea. It is subject for further development and in the future it will be shipped as a part of the finished biomolecular analysis instrument from Q-linea.

Abstract:
Minimizing power consumption is a critical part of many embedded design projects. The challenge is to limit the power consumption of the system and at the same time provide satisfactory service to the user. With regards to microprocessors, the main way of limiting power consumption during program execution is to adjust the frequency and the voltage at which the processor operates. To enable the implementation of real-time scheduling with support for dynamic voltage and frequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor is performed. Specifically, the power consumption relationship to all relevant frequency and voltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-time environment, a complete timing analysis of proposed voltage and frequency scaling methods is performed and their suitability for use in real-time systems is evaluated. To integrate voltage and frequency scaling capability into OSE RTOS, a software module has been developed for this operating system. The module enables OSE processes to request voltage and frequency changes using a signaling interface. The module has been tested for robustness and its correct operation together with a real-time dynamic voltage frequency scheduler developed at Enea has been verified. Finally, an evaluation of the power consumption of a test program running on the integrated system is performed.<br>Att minimera energiförbrukning ar en mycket viktig del av många utvecklingsprojekt av inbyggda system. Utmaningen består av att minimera systemets energiförbrukning samtidigt som det förväntas leverera en kvalitativ användarupplevelse. Den huvudsakliga metoden som används för att minimera energiförbrukningen en mikroprocessor under programexekvering är att reducera dess klockfrekvens och matningsspänning. För att möjliggöra implementationen av realtidsschemaläggning med stöd for dynamisk justering av processorns spänning och frekvens genomförs en utförlig studie av en Freescale i.MX31- mikroprocessor. Undersökningen fokuserar på relationen mellan energiförbrukning och spannings- och frekvensinställningar. För att möjliggöra frekvens- och spänningsskalning i realtidssammanhang utförs dessutom en tidsanalys av föreslagna spännings- och frekvensjusteringsmetoder och deras lämplighet for användning i realtidssystem utvärderas. För att integrera spännings- och frekvensskalning i OSE RTOS har en mjukvarumodul för operativsystemet utvecklats. Modulen gör det möjligt for OSE-processer att begära spännings- och frekvensändringar genom ett signalinterface. Modulen testas for robusthet och dess korrekta funktion tillsammans med en realtidsschemaläggare med stöd för dynamisk frekvens- och spänningsskalning utvecklad hos Enea verifieras. Slutligen så utvärderas energiförbrukningen av ett testprogram som exekveras av det integrerade systemet.

Abstract:
<p>Development and construction of an electronic Breakout box is the main work for this thesis. The box is a part of a test system for the component Fuel Flow Transmitter and should convert signals to be suitable for a frequency counter. A previously constructed Breakoutbox for this purpose is being old and needed to be recreated. So SAAB Aerotech, Aircraft services, the company for the thesis work wanted to construct a new, more sustainable Breakoutbox adapted to a more modern technology. The signals to the box comes from the transmitter and should be converted to suitable signals for a frequency counter so it can show pulse and time difference between the signals. Both a digital and an analog approach for this purpose have been examined in the work. The result was that the analog solution worked better because the conversion could be performed with OP-amplifier instead of algorithms in a microprocessor. Many problems occured in this thesis work that wasn’t included in the beginning so the most important property proved to be the ability to solve this problems. The Breakout box finally met the requirements from the specification and will in the future be used instead of the old Breakout box as a component in the test system for the Fuel Flow Transmitter.</p><br><p>Det här arbetet handlar om att utveckla och konstruera en elektronisk Breakoutbox som används vid tester av bränslekomponenten Fuel Flow Transmitter. En tidigare konstruerad Breakoutbox för detta ändamål började bli gammal och behövde förnyas. SAAB Aerotech avdelning Aircraft Services, som examensarbetet utfördes åt, ville därför konstruera en ny, mer hållbar Breakoutbox som är anpassad till en modernare teknologi. Insignalerna till boxen kommer från transmittern och ska omvandlas så att en frekvensräknare kan visa pulstid samt tidsdifferens mellan dem. Både ett digitalt och ett analogt tillvägagångssätt för att omvandla signalerna har undersökts under arbetets gång. Resultatet blev att den analoga lösningen fungerade bättre för detta ändamål då omvandlingen kunde utföras med OP-förstärkare istället för algoritmer i en mikroprocessor. Den viktigaste egenskapen i arbetet visade sig vara problemlösning då många problem dök upp under arbetets gång som inte var medräknade från början. Breakoutboxen uppfyllde till slut de krav som fastställdes från början. Boxen kommer i fortsättningen att användas istället för den gamla Breakoutboxen som en komponent i bränsletestkedjan för Fuel Flow Transmittern.</p>

Abstract:
Epilepsy is a disability with a large research field but yet with little knowledge and understanding about finding a cure. The common idea as to why an epileptic seizure is triggered is because of over activity in the neurons of the brain. More than 60 000 people in Sweden suffer from epilepsy. Damages from an epileptic seizure can be life threatening if left uncontrolled and a solution is needed in order to detect and alarm if a seizure has appeared. This project refers to building a system that can detect a seizure and locate the position of the patient having the seizure. This system also creates the possibility for a contact person to take part of the information. As there were no persons with the diagnose epilepsy at hand, the project group decided that simulated seizures were necessary. Development of the system has been categorised into three subsystems. The subsystems are a bracelet unit, a mobile application and a cloud-service. The projects subsystems were developed and the system was completed. A bracelet unit was created. This bracelet is able to detect if an epileptic seizure has occurred. A Bluetooth low energy connection between the bracelet and the mobile application was enabled making it possible for an alarm to be sent to a contact person during a seizure.

Abstract:
<p>På Alfred Nobelmuseet i Karlskoga finns en avdelning som kallas Fiffiga huset. Där finns många experiment som besökare kan prova på, samt montrar som visar hur olika tekniska och maskinella apparater fungerar. Till utställningen och öppnandet sommaren 2009 ville de ha två nya demonstratorer. I rapporten kallas dem för reaktionstidsväggen och baklängesprataren. Reaktionstidsväggen skulle mäta besökarens reaktionstid genom att tryckknappar, med inbyggda dioder som slumpvis tänds, trycks ned i rätt ordning. Baklängesprataren skulle spela in besökarens tal och sedan spela upp det baklänges. Tanken var att besökaren skulle försöka prata baklänges och få det att låta rätt vid uppspelning. Arbetet gick ut på att bygga dessa demonstratorer och montera dem i Fiffiga huset. Reaktionstidsväggen styrdes med hjälp av en mikroprocessor ATMega16 från Atmel. Dess jobb var att läsa av knapptryckningar samt skicka information till dioder och display. Även baklängesprataren skulle styras med hjälp av mikroprocessorn ATMega16. En enkel mikrofonförstärkare samt filter till högtalarna skulle anslutas till processorn. Det inbyggda minnet skulle inte räcka till så ett extern minne behövde anslutas.Endast reaktionstidsväggen hann bli färdig inom projektets ramar eftersom all gammal elektronik som medföljde från Nobelmuseet var komplex, samt att många kortslutningar och avbrott gjorde felsökning till en tidskrävande procedur.</p>

Abstract:
I projektet utreds möjligheterna kring att kunna kontrollera en generators reaktiva effektproduktion genom att styra magnetiseringsströmmen från en PLC. Som metod för styrning från PLC beslutades att en signal på 0-5V skulle användas. För att reglera magnetiseringen, och därmed i förlängningen den reaktiva effekten, beslutades att den befintliga manuella potentiometern skulle ersättas med två parallellkopplade digitala potentiometrar av typen MCP4261 som kontrollerades av en mikrokontroller. Att de digitala potentiometrarna skulle parallellkopplas beslutades efter en förstudie som visade på att det skulle resultera i en noggrannare reglering utan någon inskränkning på användbart reglerspann. Praktisk provning av mikrokontroller och digitala potentiometrar gav ett tillfredsställande och bra resultat med god upplösning.<br>This project investigates the possibilities of being able to control a generators reactive power production by controlling the excitation current from a PLC. As a method for controlling from PLC, it was decided that a signal of 0-5V should be used. In order to regulate the magnetization, and hence in the long term the reactive power, it was decided that the existing manual potentiometer would be replaced by two parallel-connected digital potentiometers of the type MCP4261 controlled by a microcontroller. The fact that the digital potentiometers would be connected in parallel was decided after a feasibility study which showed that in this way it would result in a more accurate regulation without any restriction on the usable control span. Practical testing of microcontrollers and digital potentiometers provided a satisfactory result with a good resolution.

It was solved using a magnetic position sensor. After testing the control algorithm was designed my own hardware for control the BLDC motor. The main control unit was chosen microprocessor MC56F82743, which is designed specifically for BLDC motor control. The microprocessor was programmed in the CodeWarrior development environment, using a JTAF and USB-TAP.

The aim of this work is to design a communication module for laboratory source Manson. This power supply communicates only through a serial RS-232 link. Modern computers usually use for the connection with other peripherals mainly USB. Designed communication module contains converter between the RS-232 and USB. Power supply is used in the automated measurement setup, which is controlled from the Virtual Engineering Environment from the Agilent Technologies. Direct commands for laboratory source Manson are not compatible with the SCPI (Standard Commands for Programmable Instruments) standard commands. So, the communication module converts commands from the SCPI format to Manson supply instructions. The communication with the Manson supply will be obvious for students by using new communication module.
