Remote Control Power Management via Host Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for effective power management in battery-powered peripheral devices that provide two-way communication and require power management beyond simple push-button operations, especially in devices like wireless computer keyboards and TV remote controls that typically only use power for transmission or when a button is pressed.
Innovation Solution
A method and system where a host control device detects the status indication of a remote control device, monitors user presence through sensor data, and outputs a control signal to the remote control device to enter a low power state, allowing for dynamic power management and maintaining two-way communication during active use while conserving battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote control device remains in a powered-on state to maintain two-way communication and responsiveness, then the device functionality and user experience are improved, but the battery power is consumed faster
Solution Approach 1:
The patent implements dynamic power management by transitioning the remote control device between different power states (fully powered-on, low-power state, and fully powered-off) based on real-time operational needs. The host control device monitors usage patterns and sends commands to adjust the power state, allowing the system to adapt between reliability and energy consumption requirements.
Solution Approach 2:
The remote control device automatically transitions to low-power or powered-off states when not in use, without requiring manual user intervention. The host control device monitors the operational status and autonomously manages the power state transitions, enabling the system to self-regulate power consumption based on actual usage patterns.
2Use of energy by moving object
If the remote control device enters a low power state to conserve battery, then energy consumption is reduced, but the device responsiveness and communication capability are delayed
Solution Approach 1:
The host control device predicts when the remote control device will be needed based on usage patterns and proactively wakes it up before actual use is required. This preliminary action ensures the device is ready when needed while maximizing the time spent in low-power states, thus reducing both energy consumption and perceived activation delay.
Solution Approach 2:
The system implements a feedback mechanism where the host control device monitors usage patterns and operational status of the remote control device. Based on this feedback, the host dynamically adjusts power state transitions, optimizing the balance between battery conservation and responsiveness by learning from actual usage behavior.

AI summary
The present disclosure relates to power management of a remote control device by a host control device. In one embodiment, a method for power management includes detecting, by a host control device, a status indication of the remote control device, wherein the status indication is associated with a power-on state of the remote control device. The method also includes monitoring received sensor data associated with user presence, and outputting a control signal to the remote control device for the remote control device to enter a low power state. Power management may be provided for loudspeaker units, communications devices, and display devices.
