  1. 21. Ultrasound sensor for gas concentration measurement

    Uppsats för yrkesexamina på avancerad nivå, KTH/Mikrosystemteknik

    Författare :Sheng Pang; [2011]
    Nyckelord :;

    Sammanfattning : In an anesthesia machine, there is a need to monitor the anesthesia concentration that is being delivered to the patient, mainly to stop and flush the system in case of fault but also to control the dosage of anesthesia. The infrared sensor with absorption spectrometry technology that Maquet use today is expensive and the desire for a cheaper solution leads to this master thesis. LÄS MER

  5. 24. Localization and tracking using an heterogeneous sensor network

    L3-uppsats, KTH/Reglerteknik

    Författare :José Araújo; [2008]
    Nyckelord :;

    Sammanfattning : Taking resource limitations into account in the design of wireless sensor networks are important in many emerging applications. The need for minimizing the communication and power consumption of individual nodes and other units pose interesting challenges for estimation and control strategies. LÄS MER

  7. 25. Tyre Pressure Monitoring using Sensors

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Tove Bergdahl; [2007]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis presents an implementation of a positioning and navigation system for a mobile robot using ultrasonic pulses and passive sensors that are part of a sensor network. The system uses the Telos Tmote Sky sensor-boards running Contiki. LÄS MER
