One question, twenty years

The device says something happened. How do you know it did?

  1. 2005–11 Vehicles & traffic OBD vehicle communication, RFID attendance, smart traffic systems
  2. 2013–15 Remote monitoring UPS units, generators and passenger information systems
  3. 2018–20 M2M networks Security for a network of distributed machines in Belgium
  4. 2024–25 EV charging Distributed architecture for charging-station management software
  5. 2025–26 Screens on the move A mobility DOOH network on scooters and vehicles, built from zero
  6. 2026– Verifiable playback ibibik
