  1. 1. Wristband Design for Pool Safety System : Redesign of Multifunctional Wearables for Drowning Detection

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Jonas Larsson; Johan Carlén; [2017]
    Keywords : Industrial design engineering; pool safety; human-centred design; wristband design; wearables; Teknisk design; poolsäkerhet; användarcentrerad design; armbandsdesign; wearables;

    Abstract : Every year, people are injured or even drowns in pools all over the world. Even in pools with monitoring lifeguards, accidents happen. One reason for submerge injuries or drownings is that they often are silent, which make incidents hard to detect. READ MORE

  3. 2. Offset-PLL based frequency up-conversion for low spurious transmission

    University essay from Institutionen för systemteknik

    Author : Anders Nilsson; [2003]
    Keywords : Electronics; Offset-PLL; low spurious; up-conversion; radio; transmitter; modulator; Elektronik;

    Abstract : The goal of this final year project is to investigate various techniques to up-convert a baseband signal into radio frequency signals, and to investigate the practical problems encountered in an offset phase locked loop design by implementation. Phase locked loops are commonly used in radio transmitters and receivers to generate accurate RF signals from a low-frequency reference. READ MORE

  4. 3. 2.4 GHz Power Amplifier with Cartesian Feedback for WLAN

    University essay from Institutionen för systemteknik

    Author : Maria Hofvendahl; [2002]
    Keywords : Electronics; Linearisation; Cartesian feedback; IMD; 1dBcompression point; PA; mixer; subtracter; adder; RF; Elektronik;

    Abstract : This final year project describes the linearisation method Cartesian feedback and the design of such a feedback with a 2.4GHz power amplifier. To investigate the functionality of the Cartesian feedback ideal blocks with no current consumption were made and then gradually analog circuits were introduced into the feedback. READ MORE
