  válasz VikMorroHun #21010 üzenetére

  Érdekelt a téma, ezért egy picit utánanéztem.
  Ezt találtam: (ez speciel az LG AI wash)
  
  LG's AI DD™ (Artificial Intelligence Direct Drive) technology detects fabric softness by analyzing the electrical currents and feedback from the motor while the drum is moving.

  Instead of using cameras, it measures how the motor responds to the resistance and momentum of the clothes inside.

  How the Detection Works
  The system follows a two-step "sensing" process before the wash begins:

  Weight Detection (Inertia}: The drum performs brief rotations and stops to measure the amount of electrical current required to accelerate the load. Heavier loads require more current to move.

  Softness Detection (Back-EMF): The machine monitors the "voltage kickback" or Back-EMF when the motor suddenly stops or changes speed.
  Stiff fabrics (like denim) strike the drum wall more rigidly, creating a sharp, clean electrical signal.

  Soft fabrics (like delicate cottons) deform and absorb energy, leading to a "muddier" or dampened electrical feedback.

  AI Analysis and Action
  Big Data Comparison: The sensed data is compared against a pre-installed database of over 20,000 washing patterns.

  Motion Optimization: Based on the identified fabric profile, the AI selects the optimal combination of 6 Motion Direct Drive patterns (such as stepping, filtration, or swing) to minimize fabric damage.

  Operational Limits: This advanced sensing typically only activates for loads under 3kg (roughly 6.6 lbs) and is disabled if the Steam option is manually selected.

  Note: In newer AI DD 2.0 models, the machine may also use an optical sensor to measure light refraction in the water, which helps detect soil levels and further adjust the cycle
