Interface Controller for External Device Link Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hosts may incorrectly determine that external electronic devices are not connected due to the time required for device main bodies to reach a mechanically stable state, leading to delayed or erroneous link information retrieval.
Innovation Solution
An interface controller transmits a termination-on signal to the host before the device main body reaches a mechanically stable state, and responds with default link information in a delayed manner until the device is stable, then provides specific link information once stable, allowing sufficient time for stabilization.

Engineering Contradiction Analysis
1Reliability
If the host waits for the device main body to reach a mechanically stable state before retrieving link information, then the link information retrieval is accurate, but the host may erroneously determine that no external electronic device is coupled due to the long time required
Solution Approach 1:
The interface controller performs preliminary actions by sending a termination-on signal to the host before the device main body reaches a mechanically stable state. This preliminary notification allows the host to prepare for link information retrieval without waiting for the full stabilization time, thereby reducing the time loss while ensuring accurate retrieval when the device is ready.
Solution Approach 2:
The interface controller acts as an intermediary between the device main body and the host. It manages the timing and coordination of the termination-on signal and link information retrieval process, mediating between the host's need for quick detection and the device main body's requirement for stabilization time before providing accurate link information.
2Speed
If the host immediately retrieves link information after power-on, then the detection is timely, but the device main body may not be mechanically stable leading to erroneous determination
Solution Approach 1:
The interface controller sends a termination-on signal as a preliminary action before the device main body is fully stabilized. This allows the host to initiate the link information retrieval process earlier than waiting for full stabilization, improving detection speed while the interface controller ensures the actual retrieval occurs at the appropriate time when the device is stable.
Solution Approach 2:
The interface controller implements a feedback mechanism by monitoring the mechanical stable state of the device main body and coordinating the link information retrieval timing accordingly. The controller provides feedback to the host about when the device is ready for accurate link information retrieval, ensuring both timely detection and reliable accuracy.

AI summary
An interface controller, coupling a device main body of an external electronic device to a host, is disclosed, which transmits a termination-on signal to the host prior to a mechanically stable state of a device main body of the external electronic device. When the device main body has not reached the mechanically stable state yet, the interface controller responds to the host with default link information in a delayed manner. The default link information is contained in the interface controller. When the device main body reaches the mechanically stable state, the interface controller transmits specific link information retrieved from the device main body to the host.
