Saab Microwave Systems (SMW) is a business unit within Saab AB that manufactures and develops different types of radar- and Sensor systems for naval, airborne and ground based forces as well as within the market for civil security. In addition to the manufacturing of radar and Sensor systems they also provide different types of service concepts. The business unit has 50 years of experience within the area of developing radar systems and is considered to be one of the market leaders. When applying an assemble-to-order production strategy with products at this level of cost price the product lead-time is vital and becomes an important part of the strategy within marketing and sales. Within SMW there is a new department called Supply Management (SM) that provides the supply of incoming and outgoing material. Within SM there are four sub-departments working with activities such as planning, purchasing, receiving inspection, storage and distribution.

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver Sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

Sverige är för tillfället operativa med Helikopter 16 - Black Hawk i Afghanistan. Uppgiften som löses i Afghanistan är främre och taktisk sjuktransport (MEDEVAC).Detta arbete handlar om hur befintliga VMS-system i helikoptrar kan kompletteras i syfte att möta ett föreliggande prickskyttehot vid lösande av främre MEDEVAC i ett insatsområde som miljömässigt liknar Afghanistan. I arbetet analyseras möjliga tekniker utifrån aspekter från ett konstruerat scenario där helikopterbesättningarnas uppgift, insatsmiljö samt hotbild beskrivs.Resultatet visar på att MEDEVAC-helikoptrar kan utrustas med Sensor-gimbaler där olika Sensorer kan kombineras, vilket möjliggör spaning i 360°. Detta bidrar till den militära nyttan då helikopterpersonalens lösande av uppgift effektiviseras, chansen till överlevnad ökar samtidigt som personal och patienter kan känna sig tryggare..

AASS (Applied Autonomous Sensor Systems, Centrum för Tillämpade Autonoma Sensorsystem) arbetar med forskning inom autonoma system. Deras stora användningsområden är utveckling av automatiska system till fordonsindustrin samt system till äldrevården.AASS, har ett önskemål om en enklare modell av en CNC fräs för enklare fräsning till bland annat prototyptillverkning. Fokus ska ligga på kostnaden då precisionen inte är av största intresse.Uppdraget innebär att ta fram en konstruktion av en cnc- router med tre axlar med ett arbetsrum på 600x450x150mm. Maskinen ska kunna skära i mjuka material som trä, plaster men även mjukare aluminium.Resultatet är en tre axlig cnc- router som drivs av tre stycken stepmotorer som är kopplade till respektive kulskruv. Cnc routern har ett arbetsrum på cirka 600x450x150mm.

This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic Sensor that works as an electronic compass.

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of Sensor range.

The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-Sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

Det finns idag goda möjligheter att beröringsfritt kontrollera elektroniska objekt. Ett exempel är belysning som aktiveras via rörelseSensorer.Enkla lösningar innehåller oftast Sensorer för ljud, ljus eller rörelse vilka används för att aktivera ett styrobjekt, vanligen genom att slå på eller av en elektronisk strömbrytare kopplad till styrobjektet. Behövs det mer säkerhet och möjlighet att bevisa för styrobjektet vem individen är som försöker få styrobjektets uppmärksamhet behövs det mer än en enkel Sensor. Det behövs en anpassning för att separera olika bluetoothenheter från varandra. Bluetooth är en teknik för att trådlöst skicka information mellan två enheter.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and Sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa Sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the Sensor can be fitted to the rolling mill.
