1. 16. Integration and Packaging Concepts for Infrared Bolometer Arrays

   Författare :Adit Decharat; Göran Stemme; Sjoerd Haasl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fabrication; Bonding; packaging; microbolometer; Thermal imaging.; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

   Sammanfattning :   Infrared (IR) imaging devices based on energy detection has shown a dramatic development in technology along with an impressive price reduction in recent years. However, for a low-end market as in automotive applications, the present cost of IR cameras is still the main obstacle to broadening their usage. LÄS MER

3. 17. Characterization of electrical properties in 4H-SiC by imaging techniques

   Sammanfattning : 4H-SiC has physical properties supremely suited for a variety of high power, high frequency and high temperature electronic device applications. To fully take advantage of the material's potential, several problems remain to be solved. LÄS MER

4. 18. Permanent-Magnet Synchronous Machines with Non-Overlapping Concentrated Windings for Low-Speed Direct-Drive Applications

   Författare :Florence Meier; Juliette Soulard; Zi-Qiang Zhu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electronic engineering; electrical engineering; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Sammanfattning :  Many geared electric drives can benefit from removing the gearbox and driving directly the load at low speed using a permanent-magnet synchronous machine (PMSM). PMSMs with non-overlapping concentrated windings are particularly attractive in low-speed direct drives since they allow, among other advantages, a high number of poles with a limited number of slots.

5. 19. Wireless video sensor network and its applications in digital zoo

   Författare :Johannes Karlsson; Haibo Li; Jerry Eriksson; Oliver Wu Dapeng; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Networks; Wireless ad-hoc Networks; Digital Zoo; Video Compression; Real-Time Video Communication; Object Tracking; Sensor Fusion; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik; signalbehandling; Signal Processing;

   Sammanfattning : Most computing and communicating devices have been personal computers that were connected to Internet through a fixed network connection. It is believed that future communication devices will not be of this type. Instead the intelligence and communication capability will move into various objects that surround us. LÄS MER

7. 20. On the Design, Characterization and Optimization of RFID Tag Antennas

   Författare :Johan Sidén; Hans-Erik Nilsson; Heikki Seppä; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik;

   Sammanfattning : Remotely read electronic identification tags are establishing as the standard method of identifying objects in transport logistcs. They are referred to as RFID tags and with successful research and development they are likely to one day replace all of todays barcodes, found on a wide variety of items and objects.
