1. Step 1. Engine control unit — is used in — Anti-lock braking system (ABS). The ABS unit.
2. Step 2. Anti-lock braking system (ABS) — has part — Hall sensor. Sensors measure the wheel speed.
3. Step 3. Hall sensor — uses — Electron. The magnetic field deflects the electrons.
4. Step 4. Electron — is used in — Electron microscope. A beam of electrons instead of light.
5. Step 5. Electron microscope — has part — Vacuum pump. A vacuum in the column.
