Physical Modelling

  • Self-winding mechanism
  • Barrel
  • Oscillator
  • Gong timbre
  • Gear design
  • Effects of wrist movements on the mechanism
  • Flexible beams

Metrology (algorithms)

  • Image processing: automatic pointer detection
  • Accelerometers and gyroscopes to capture the wrist movements
  • Robust statistics for possibly noisy measurements
  • Acoustic measurements (ticking of the watch)
    • Multi-oscillators
    • High frequencies
    • Robust to low signal-to-noise ratio
  • Optical measurements (detection of rotating arms by a laser)
    • Tourbillon / Triple axis tourbillon
    • Damped oscillators
