RSSI Proximity Detection Using Financial Technical Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the proximity of radio frequency devices are hindered by signal strength fluctuations due to environmental factors, making it difficult to accurately measure distance for applications like location-based services and security systems, especially when devices are not permanently discoverable or require user intervention.
Innovation Solution
A method involving periodic measurement of RSSI values using technical indicators such as exponential moving averages and moving average convergence/divergence to analyze changes in proximity between radio frequency devices, allowing for accurate determination of relative movement and proximity without the need for a profile-dependent connection or device discoverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RSSI measurements are used to determine proximity between radio frequency devices, then distance estimation can be obtained, but signal strength fluctuations due to environmental factors reduce measurement accuracy
Solution Approach 1:
The patent transforms the RSSI measurement approach by applying financial technical analysis parameters (moving averages, convergence/divergence indicators) to the signal strength data. This changes the parameter representation from raw signal strength to processed technical indicators that filter out environmental fluctuations while preserving proximity information.
Solution Approach 2:
The patent introduces technical analysis indicators as intermediary elements between the raw RSSI measurements and the proximity determination. These intermediaries (moving averages, MACD) act as filters that eliminate the harmful effect of signal fluctuations while maintaining the useful proximity information.
2Ease of operation
If traditional Bluetooth proximity detection is used, then device discoverability enables connection establishment, but user intervention is required to change discoverability status
Solution Approach 1:
The patent implements self-service by enabling the receiving device to autonomously perform proximity detection and trigger switch operation without requiring user intervention. The device automatically measures RSSI, processes the data through technical indicators, and activates the switch when proximity threshold is met, eliminating the need for users to manually manage discoverability settings.
Solution Approach 2:
The patent applies preliminary action by having the receiving device continuously or periodically measure RSSI values and prepare technical analysis indicators in advance. This allows the system to be ready to detect proximity changes and trigger switch operation immediately when the user approaches, without requiring real-time user initiation.
3Reliability
If profile-dependent Bluetooth connections are established for switch control, then reliable communication is achieved, but connection establishment requires user action and device discoverability
Solution Approach 1:
The patent extracts the proximity detection function from the profile-dependent connection requirement. By using RSSI measurements and technical analysis indicators, the system separates the proximity detection capability from the need for established Bluetooth profiles, allowing automatic trigger detection without requiring full connection establishment.
Solution Approach 2:
The patent applies partial action by performing only the essential RSSI measurement and technical analysis needed for proximity detection, rather than establishing complete profile-dependent connections. This partial approach achieves the necessary communication reliability for proximity detection without the overhead of full connection establishment.
