Sensor-Controlled RF Power Interrupters for Personnel Exposure Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mitigating RF radiation exposure, such as signs and barriers, fail to effectively alert personnel of current radiation levels and can interfere with network performance, posing risks of exposure and regulatory non-compliance.
Innovation Solution
An RF infrastructure sentry system with sensors, a processor, and a relay that temporarily interrupts power to RF radiation sources when personnel enter a danger zone, using AI cameras and machine learning for human detection, and providing visual and auditory warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional signs and barriers are used to warn personnel of RF radiation exposure, then regulatory compliance is attempted, but the signs do not indicate current operational status and barriers interfere with network performance
Solution Approach 1:
The patent replaces mechanical barriers with an automated electronic system consisting of sensors, processors, and power interrupters. This electronic system detects human presence and automatically interrupts RF power without requiring physical barriers, thus maintaining regulatory compliance while eliminating network performance interference.
Solution Approach 2:
The system provides self-service by automatically detecting human presence through sensors and autonomously interrupting RF power through the processor-controlled power interrupter. The system monitors and responds to conditions without human intervention, eliminating the need for manual barrier management and continuous signage updates.
2Loss of information
If conventional signs are placed at RF radiation sites, then warning information is provided, but personnel may not see or may choose to ignore the signs
Solution Approach 1:
The patent replaces passive mechanical signs with an active electronic detection and response system. Instead of relying on personnel to read and heed static signs, the system uses sensors to detect presence and automatically interrupts RF power, ensuring protection is actively delivered rather than passively communicated.
Solution Approach 2:
The system implements feedback by continuously monitoring the environment with sensors for human presence and automatically responding by interrupting RF power when detected. This closed-loop feedback mechanism ensures that warning information is translated into actual protective action based on real-time conditions.
3Reliability
If barriers are installed to prevent entry into RF radiation zones, then physical protection is provided, but workers can intentionally climb over barriers or unknowingly enter hazardous areas
Solution Approach 1:
The patent replaces physical barrier systems with an electronic detection and control system. Sensors monitor for human presence in the hazard zone, and the processor automatically activates power interrupters to stop RF transmission, providing protection without requiring physical barriers that can be circumvented.
Solution Approach 2:
The system introduces an intermediary electronic control layer between human presence and RF radiation exposure. Rather than relying on physical barriers alone, the patent uses sensors and power interrupters as intermediaries to detect and respond to human presence, automatically mediating the interaction between personnel and RF sources.
Data Source
AI summary
An RF infrastructure sentry system includes one or more sensors configured to detect that an object has entered an area of concern proximate to an RF radiation source and an RF mitigation system operatively connected to the one or more sensors. The RF mitigation system includes an electrical input operatively connected to a power supply for the RF radiation source; an electrical output operatively connected to the RF radiation source; a relay disposed on an electrical path between the electrical input and the electrical output and configured to selectively connect or disconnect the electrical input and the electrical output through the electrical path; and a processor operatively connected to the relay and configured, at least in response to detection by the one or more sensors that the object has entered the area of concern, to open the relay to temporarily interrupt power to the RF radiation source.
