Dual Controller Input Angle Detection for Wake-Up Misoperation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic apparatuses in PAD mode cannot control the keyboard and touch panel to be in a turn-off state during the wake-up period from a sleeping state to an operating state, leading to potential faulty operations and reduced user experience.
Innovation Solution
A method and device utilizing a first controller that is not affected by the sleeping state of the electronic apparatus, which obtains and determines the angle between the input apparatus and display unit, and controls the input apparatus to be in a turn-off state when the angle satisfies a preset condition, ensuring the keyboard and touch panel are turned off even when the CPU is in a sleeping state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the CPU enters sleeping state to save energy, then energy consumption is reduced, but the keyboard and touch panel cannot be controlled to turn off during wake-up period
Solution Approach 1:
The patent divides the control system into two independent controllers: a first controller that remains operational during wake-up period to manage input apparatus, and a second controller (CPU) that enters sleeping state for energy saving. This segmentation allows the first controller to independently handle the keyboard and touch panel control without waiting for the CPU to wake up, resolving the contradiction between energy saving and control reliability.
Solution Approach 2:
The first controller performs preliminary action by detecting the angle between input apparatus and display unit before the CPU fully wakes up, and proactively controls the input apparatus to turn off based on preset conditions. This preliminary control action ensures the keyboard and touch panel are properly managed during the critical wake-up period, preventing misoperations while the CPU transitions from sleeping state.
2Ease of operation
If the keyboard and touch panel remain on during wake-up period, then user operation is convenient, but misoperations occur in PAD mode
Solution Approach 1:
The first controller performs preliminary detection of the angle between input apparatus and display unit before enabling full user operation. Based on this preliminary angle detection, the system proactively determines whether to keep the input apparatus on or turn it off, preventing misoperations in PAD mode while maintaining ease of operation in other modes.
Solution Approach 2:
The system continuously monitors the angle between input apparatus and display unit and uses this feedback information to dynamically adjust the state of the input apparatus. When the angle indicates PAD mode configuration, the system provides feedback to turn off the input apparatus, thereby preventing misoperations while maintaining user convenience in other operating modes.

AI summary
A method for automatic control is provided, which is applied to an electronic apparatus including a first controller, a second controller, a first input apparatus and a first display unit. The first input apparatus is rotatablely connected to the first display unit. When the electronic apparatus is in a sleeping state, the second controller is in a sleeping state and the first controller is in an operating state. The method includes: obtaining a first angle between the first input apparatus and the first display unit in the case that the electronic apparatus is in the sleeping state; determining whether the first angle satisfies a first preset condition; and controlling the first input apparatus to be in a turn-off state by the first controller in the case that the first angle satisfies a first preset condition.
