    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting interface; thermoelectric generator; glucose biofuel cell; power management; dc-dc converter; boost converter; zero-current switching; zero-voltage switching; implantable biosensor; Energiskördsgränssnitt; termoelektrisk generator; glukosbiobränslecell; energihantering; DC-DC-omvandlare; boost-omvandlare; inplanterbar biosensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Energy harvesting is identified as an alternative solution for powering implantable biosensors. It can potentially enable the development of self-powered implants if the harvested energy is properly handled. This development implies that batteries, which impose many limitations, are replaced by miniature harvesting devices. LÄS MER

  4. 13. Applications of decision diagrams in digital circuit design

    Författare :Per Lindgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inbyggda system; Embedded System;

    Sammanfattning : Design methodology of digital circuits is a rapidly changing field. In the last 20 years, the number of transistors on a single chip has increased from thousands to tens of millions. This sets new demands on the design tools involved, their ability to capture specifications on a high level, and finally synthesize them into hardware implementations. LÄS MER

  5. 14. Main-circuit considerations of power coverters for integral motors

    Författare :Karsten Kretschmar; Hans-Peter Nee; Johan Walter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Permanent magnet integral motor; Small DC link; Elektronik; Electronics; Elektronik;

    Sammanfattning : This thesis deals with different converter topologies for a 15kW permanent magnet (PM) integral motor. An integral motor combines the motor and the power electronics in one unit. The main objective is to find suitable converter alternatives for an integral motor. LÄS MER

  7. 15. Discrete-Time Cellular Neural Networks Implemented on Field-Programmable Gate-Arrays to Build a Virtual Sensor System

    Författare :Suleyman Malki; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellular Neural Networks; Image processing; Discrete-Time Cellular Neural Networks; Packet switching; FPGA; Velocity measurement; Autowaves; Robot navigation;

    Sammanfattning : Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. At first glance a pipelined approach, based on circuit switching, seems promising. LÄS MER
