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

    Author : Henrik Mellin; [2022]
    Keywords : Penetrationtesting; Internet of Things; Threatmodeling; BluetoothLowEnergy; Firmware analysis; Reverse engineering; Penetrationstestning; Sakernasinternet; Hotmodellering; BluetoothLowEnergy; Analys of fast programvara; Baklängeskonstruktion;

    Abstract : This thesis is about cyber-security and penetration testing. More specifically it concerns penetration testing of a Hövding bicycle airbag which is a smart alternative to a traditional bicycle helmet. The thesis focuses on exploiting Bluetooth Low Energy, firmware analysis and reverse engineering. READ MORE

  3. 2. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

    University essay from KTH/Hållfasthetslära

    Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
    Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

    Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

    Author : Anton Nordmark; [2019]
    Keywords : industrial design engineering; human–computer interface; sound design; audiotactile design; crossmodal attention; bone conduction headphones; multimodal collision warnings; vulnerable road user VRU ; V2Cyclist; C-ITS; V2X; B2V; teknisk design; användargränssnitt; ljuddesign; taktildesign; korsmodal uppmärksamhet; benledande hörlurar; multimodala kollisionsvarningar; sårbara trafikanter; V2Cyclist; C-ITS; V2X; B2V;

    Abstract : Traffic is a complex environment in which many actors take part; several new technologies bring promises of reducing this complexity. However, cyclists—a particularly vulnerable road user group—have so far been somewhat put aside in these new developments, among them being Cooperative Intelligent Traffic Systems (C-ITS) and their aspects of human–computer interaction.

  5. 4. Concept Design to Enhance Rearward Perception for Cyclists

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Andreas Lif; [2017]
    Keywords : ;

    Abstract : Although cyclists travel on many of the same roads as cars, motorcycles and mopeds, bicycles are rarely outfitted with rear view mirrors as these vehicles are. Instead, most cyclists rely on looking over their shoulder to assess their situation, which can cause discomfort and disorientation and also means taking their eyes off the road ahead. READ MORE

  6. 5. Ephemeral Selves: A semiotic cultural analysis of a Swedish bicycle helmet campaign

    University essay from Lunds universitet/Avdelningen för etnologi

    Abstract : In 2014, Lund municipality in Sweden handed out 830 bicycle helmets for free. Such governance campaigns are commonplace in Sweden, yet no campaign has ever been evaluated. There are two research aims to this thesis. First, to evaluate how many of the 830 cyclists actually wear the bicycle helmets that they received. READ MORE
