Controller Power Supply Restoration After Reboot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses face challenges in restarting power supply to external devices after a system reboot, leading to inconsistent power restoration based on the previous power state.
Innovation Solution
The apparatus stores history information about power supply to external devices in a memory and uses this information to restart power supply after a reboot, ensuring that the power state before the reboot is accurately restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system is rebooted during power supply to external devices, then the system can be updated or maintained, but the power supply state to external devices becomes inconsistent and may not be appropriately restored
Solution Approach 1:
The controller stores the power supply state information in memory before the reboot occurs. This preliminary action preserves the power supply state so that it can be restored after the reboot, preventing information loss and ensuring reliable power restoration to external devices.
2Adaptability or versatility
If the system stops power supply during reboot, then the reboot can be executed, but the external devices may not receive appropriate power restoration after reboot
Solution Approach 1:
The controller uses the stored power supply state information as feedback to determine how to restore power supply after the reboot. By referencing the previously stored state, the controller can accurately restore power to external devices, ensuring both adaptability and reliability in the power supply restoration process.

AI summary
An information processing apparatus includes: an interface; and a controller. The controller executes: storing, into a memory, history information relating to supply of electric power to an external device via the interface; rebooting when the reboot is required during supply of the electric power to the external device via the interface; and restarting control of the supply of the electric power to the external device via the interface, based on the history information stored in the memory.
