SYSTEM COMPRISING A MAIN ELECTRICAL UNIT AND A PERIPHERAL ELECTRICAL UNIT

摘要

The invention relates to a system comprising a main electrical unit (2) and a peripheral electrical unit (3, 4,5), wherein the main electrical unit and the peripheral electrical unit are switchable between a low-power mode and a high-power mode. The main electrical unit is adapted to hand over a control of the system to the peripheral electrical unit, if the peripheral electrical unit is in the high-power mode, and to switch from the high-power mode to the low-power mode, after the control has been handed over. The peripheral electrical unit is adapted to receive the control from the main electrical unit and to control the system, if the peripheral electrical unit is in the high-power mode. This allows the system to be still in operation mode, although the main electrical unit has been switched to the low-power mode, thereby reducing the power consumption of the system.

主权项

1. A system comprising a main electrical unit and a peripheral electrical unit, wherein the main electrical unit is a control unit adapted to initially control the system, wherein the peripheral electrical unit is adapted for being initially controlled by the main electrical unit,
wherein the main electrical unit and the peripheral electrical unit are switchable between a low-power mode and a high-power mode, wherein the main electrical unit is adapted to hand over a control of the system to the peripheral electrical unit, if the peripheral electrical unit is in the high-power mode, and to switch from the high-power mode to the low-power mode, after the control has been handed over, wherein the peripheral electrical unit is adapted to receive the control from the main electrical unit and to control the system, if the peripheral electrical unit is in the high-power mode.
