    Sammanfattning : Advancements in photonic integrated circuits, so-called PICs, have progressed fast in the last decades. More complex PICs are getting developed, which are promising in possibly offering advantages like low power consumption and high-performance computing. Re-programmable photonic FPGAs are one of these candidates. LÄS MER

  5. 4. Gauntlet-X1: Smart Glove System for American Sign Language translation using Hand Activity Recognition

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Asif Mohamed; Paul Sujeet; Vishnu Ullas; [2020]
    Nyckelord :;

    Sammanfattning : The most common forms of Human Computer Interaction (HCI) devices these dayslike the keyboard, mouse and touch interfaces, are limited to working on atwo-dimensional (2-D) surface, and thus do not provide complete freedom ofaccessibility using our hands. With the vast number of gestures a hand can perform,including the different combinations of motion of fingers, wrist and elbow, we canmake accessibility and interaction with the digital environment much more simplified,without restrictions to the physical surface.

  7. 5. Achieving Optimal Alignments of IR Source and Detector in Waveguide Based Gas Sensor

    Uppsats för yrkesexamina på grundnivå, KTH/Medicinteknik och hälsosystem

    Författare :Sefik Güler; Agbai Randolph Agwu; [2020]
    Nyckelord :Non-dispersive infrared technology; microelectromechanical systems; infrared light; electromagnetic spectrum; gas sensor; light emitting diode; photodiode detector; Icke-dispersiv infraröd teknologi; mikroelektromekaniska system; infrarött ljus; elektromagnetiskt spektrum; gassensor; lysdiod; fotodioddetektor;

    Sammanfattning : I takt med att tekniken för mikroelektromekaniska system utvecklas uppkommer det nya områden för tillämpning. Ett område är inom gassensorer där icke-dispersiv infraröd strålning används genom att mäta absorptionen hos olika gaser för att bestämma mängden av en specifik gas i luften. LÄS MER
