Periodic Action

a) Replace a continuous action with a periodic or pulsed one.

b) If an action is already periodic, change its frequency.

c) Use pauses between impulses to perform additional actions.
 

EXAMPLE:
  1. To intensify the heat exchange in a combustion chamber, the gas is applied in pulses.
  2. If several programs are running simultaneously on a computer, the tasks with lower priority are executed between those with higher priority. Details
