Abstract
A device for controlling a power distribution to subsystems, has a power input to be connected to a power source, a primary power output to be connected to a primary device; at least one secondary power output to be connected to at least one secondary device; sensing unit for sensing when a current level falls below a threshold in response to the primary device being turned off or going into a standby mode and when the current level raises above a threshold in response to the primary device being turned on; executing unit operatively connected with the sensing unit and operative for interrupting a power supply to the at least one secondary device when the sensing unit sense the current level below the threshold and supplying power to the at least one secondary device when the sensing unit sense the current level above the threshold correspondingly and adjusting unit for adjusting the threshold depending on a current of the primary device during periods of turning off, going into standby mode, and turning on.
