Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices operating as software-enabled access points often experience fine differences in signals, leading to inaccuracies in user identification and position determination, especially when multiple devices are involved.
Innovation Solution
An electronic device with a communication interface, memory, and processor that corrects signals received from other software-enabled access points by using correction information stored in memory, which includes artificial intelligence models to identify user presence and position, and controls other devices based on signal strength and user proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices operate as software enabled access points, then the system can provide broader coverage and redundancy, but fine differences in signals cause inaccuracies in user identification and position determination
Solution Approach 1:
The patent applies parameter changes by storing correction information that adjusts signal parameters (amplitude, phase, period) for each electronic device. When a signal is received, the processor identifies the transmitting device and applies device-specific correction parameters to normalize the signal, thereby eliminating fine differences caused by hardware variations while maintaining the benefits of multiple access points.
Solution Approach 2:
The system implements feedback by comparing received signals against stored correction information and iteratively adjusting signal parameters. The processor continuously monitors signal characteristics, applies corrections based on stored data, and updates the system state, creating a closed-loop control mechanism that improves measurement precision over time.
2Measurement precision
If signal correction information is stored for each electronic device, then signal accuracy is improved, but memory requirements and processing complexity increase
Solution Approach 1:
The patent applies local quality by storing correction information specific to each electronic device's characteristics. Instead of using a uniform correction approach for all devices, the system maintains device-specific correction data in memory, allowing targeted adjustments that improve signal accuracy while managing complexity through organized, device-oriented data storage.
