A display system, an image compensation method and a non-transitory computer readable storage medium thereof are provided. If a change in power flow of at least 5% over at time period of 1 second or less occurs and the response to the change in power flow is greater than the change in power flow a signal is generated for corrective action. Such a transportation system may be part of a device for automated production of brushes, in particular toothbrushes. The barrier layer is disposed on the insulating substrate. This method provides more flexibility when using optical switching in core networks, as it allows path optimization to new physical link connectivity, without requiring any change to the optical components such that, significant signal degradation tuning range for a WDM optical transport system is provided. The above approach has particular application in digital video broadcast services over satellite.
