  1. 1. Investigation of Light and Ultrasound Injected Signals in Microphones

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Robin Djerv; [2021]
    Keywords : LightCommands; DolphinAttack; MEMS Microphone; Signal Injection; Security;

    Abstract : Voice commanded systems (VCS) have been proved to be vulnerable to signal in- jections mimicking voice commands and explored security flaws in market avail- able products for the time of each respective study. Signal injection caused with the help of amplitude modulated ultrasonic waves (being known as DolphinAt- tacks - DA) were proved to work on several such devices in 2017. READ MORE

  3. 2. Microeletromechanical Systems for Tunable Ring Resonators on a Silicon Platform

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Chris Phong Van Nguyen; [2021]
    Keywords : Integrated photonics; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ring Resonator; Telecommunications; Integrerad fotonik; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ringresonator; Telekommunikation;

    Abstract : 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. READ MORE

  4. 3. Study of HfN as seed layer for next generation of BAW RF filters : synthesis, characterization, and investigation of piezoelectric performance

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

  5. 4. Enhancing interoperability for IoT based smart manufacturing : An analytical study of interoperability issues and case study

    University essay from KTH/Kommunikationssystem, CoS

    Author : Yujue Wang; [2020]
    Keywords : Internet-of-Things IoT ; Interoperability; Industry 4.0; FIWARE Generic Enabler; Cyber Physical Systems CPS ; Smart Manufacturing; Internet-of-things IoT ; Interoperabilitet; Industry 4.0; FIWARE Generic Enabler; Cyber Physical Systems CPS ; Smart tillverkning;

    Abstract : In the era of Industry 4.0, the Internet-of-Things (IoT) plays the driving role comparable to steam power in the first industrial revolution. IoT provides the potential to combine machine-to-machine (M2M) interaction and real time data collection within the field of manufacturing. READ MORE

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

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Asif Mohamed; Paul Sujeet; Vishnu Ullas; [2020]
    Keywords : ;

    Abstract : 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.
