  1. 1. A General Purpose Analog Circuit to Accumulate Data From Resistive Sensors

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karl Höjlund; Alan Alhallak; [2022]
    Nyckelord :Data acquisition; Wheatstone bridge; Analog conditioning; Digital potentiometer;

    Sammanfattning : Minimizing the need to physically adjust hardware platforms used for sensor measurements during the construction phase of an electric vehicle can be beneficial. Since different sensors have different measuring ranges a hardware platform used for a specific sensor might not work for another one, without physically tampering with it. LÄS MER

  3. 2. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Pablo Martinez Cano; [2019]
    Nyckelord :LISA; PCB; temperature; passive; aluminum; aluminium;

    Sammanfattning : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.

  4. 3. Design of an Analog Front-end for Ambulatory Biopotential Measurement Systems

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jiazhen Wang; [2011]
    Nyckelord :Analog front-end; biopotential measurement system; low-power;

    Sammanfattning : A critical and important part of the medical diagnosis is the montioring of the biopotential signals. Patients are always connected to a bulky and mains-powered instrument. This not only restricts the mobility of the patients but also bring discomfort to them. LÄS MER

  5. 4. Design of test hardware for characterization of key parameters of analog gas sensors

    Master-uppsats, Elektroniska komponenter

    Författare :Watchanun Tanacharoenwat; [2011]
    Nyckelord :;

    Sammanfattning : Hydrogen sensors are essential to facilitate the detection of accidental hydrogenreleases wherever hydrogen will be produced, distributed, stored, and used. Comparedto the helium detection: hydrogen is cheaper than helium, no need for avacuum and the lower cost of producing the instruments. LÄS MER

  7. 5. Occupancy Sensor System : For Context-aware Computing

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Daniel Hübinette; [2007]
    Nyckelord :context-aware; context information; correlation; occupancy; PUA; publish; sensor system; SER; SIP; thermal sensor; ubiquitous computing;

    Sammanfattning : This masters thesis project, "Occupancy Sensor System", was conducted at Kungliga Tekniska Högskolan (KTH), Stockholm, Sweden, during the period 2007-04-24 – 2007-12-17. The goal of the project was to design an occupancy sensor system that determines if there exists more than one person in a defined region. LÄS MER
