3. o Why make an ultra-slim air moving device? o Why not make a traditional fan? o What does Intel want?

4. o The device is no thicker than 3 mm o The device moves 0.075 ACFM of air o The device has a maximum pressure of 0.045 IWG

5. Passive Active Ionic Tesla valve Flapper valves Check valves Piezoelectric

6. Passive Tesla valve

7. o Modified Tesla valve design with a flat solenoid-magnet actuator o Valve works on the principle of diodicity (the ratio of the backward pressure drop to the forward pressure drop) o Valve compels fluid flow in one direction
