Input Module Hibernation Control via Signal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-saving methods in computers, such as hibernation mode, are not user-friendly as they require repeated password input or continuous sensor usage, leading to inefficiencies in power consumption and interrupted test procedures in production line systems.
Innovation Solution
An input module comprising an input device and a control program that communicates with the computer to prevent hibernation mode by issuing control signals when the device is operated, allowing users to switch between hibernation and normal modes based on their settings, using a processing unit to manage signals and maintain active computer status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the computer enters hibernation mode automatically after idle time, then power-saving efficacy is improved, but user convenience deteriorates due to repeated password input requirements
Solution Approach 1:
The system automatically detects user presence through sensor signals and activates the computer without requiring manual password input. The control unit receives sensor signals indicating user proximity and automatically issues activation commands, allowing the system to serve itself rather than requiring user intervention for wake-up operations.
Solution Approach 2:
The patent replaces the mechanical keyboard input method (typing password) with a sensor-based detection system. The sensor unit detects user presence through non-contact means (such as motion detection or proximity sensing), and the control unit processes these signals to automatically activate the computer, substituting physical keyboard interaction with automated sensor-based control.
2Ease of operation
If a sensor is used to detect user presence and prevent hibernation, then user convenience is improved, but power consumption increases due to continuous sensor operation
Solution Approach 1:
The control unit operates the sensor in periodic intervals rather than continuously. It activates the sensor only when needed (when idle time threshold is approached or user presence is detected) and keeps it inactive during active computer operation, thereby reducing overall power consumption while maintaining user convenience benefits.
Solution Approach 2:
The system performs preliminary detection using the sensor before the computer would normally enter hibernation mode. By detecting user presence in advance and triggering activation before the idle timeout expires, the system prevents hibernation without requiring continuous sensor monitoring, thus reducing power consumption while maintaining convenience.
3Loss of energy
If the computer enters hibernation mode during production line testing, then power-saving is achieved, but test procedures are interrupted
Solution Approach 1:
The control unit receives feedback signals from the testing system indicating when test operations are in progress. Based on this feedback, it determines whether to allow hibernation mode activation. When test operations are detected, the control unit prevents hibernation mode entry, ensuring test procedure continuity while still enabling power-saving during actual idle periods when no testing is occurring.
Data Source
AI summary
An input module includes an input device and a control program. The input device is in communication with a computer. The control program is installed in the computer. If a control signal from a processing unit of the input device has not been received by the computer for a predetermined time period after the control program is opened, the control program issues a command signal to the processing unit. After the command signal is received by the processing unit, the processing unit issues at least one response signal to the computer so as to prevent the computer from entering a hibernation mode.
