Master Device Sensor Coordination Reducing Power Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sensor redundancy in devices leads to inefficient power usage and underperformance, as multiple devices often have redundant sensors that are not optimized to work harmoniously together.
Innovation Solution
A method and apparatus where a master device identifies and configures other devices within a vicinity to balance sensor quality of service by determining device and application statuses, switching sensor power states, and synchronizing data, thereby reducing redundant sensor usage and optimizing power consumption.

Engineering Contradiction Analysis
1Use of energy by moving object
If multiple devices with redundant sensors operate independently, then each device can function autonomously, but power consumption increases and system performance deteriorates due to redundant sensor operation
Solution Approach 1:
The patent merges sensor operations across multiple devices by establishing a master-device architecture where one device coordinates sensor usage. The master device queries other devices about their sensor configurations and determines an optimized configuration that balances quality of service across devices, reducing redundant sensor operation and power consumption while maintaining reliable service delivery.
2Measurement precision
If all sensors in multiple devices operate at full capacity, then measurement quality is maintained, but power consumption and system complexity increase
Solution Approach 1:
The master device implements a feedback mechanism by querying other devices about their sensor configurations and operational status. Based on this feedback information, the master device determines an optimized sensor configuration that maintains measurement precision while reducing overall system complexity through coordinated sensor management.
3Loss of energy
If redundant sensors are eliminated through coordination, then power consumption decreases, but device autonomy and operational independence are reduced
Solution Approach 1:
The patent implements dynamic sensor configuration where devices can switch between autonomous operation and coordinated operation based on contextual needs. The master device determines configuration dynamically by querying device status and application status, allowing devices to maintain autonomy when needed while enabling coordinated power-saving operation when appropriate.

AI summary
A system and method for reducing sensor redundancy in sensor-equipped devices includes identifying, via a master device, at least one device within an area. The at least one device is queried to determine at least one of a device status or application status for the at least one device. A configuration of one or more sensors within the at least one device based at least in part on the querying is determined. The one or more sensors within the at least one device is configured to balance quality of service across the master device and the at least one device, based at least in part on the determining.
