Solution Overview

Problem

Current methods for tracking personnel accountability during public safety incidents, such as using hook and loop fasteners, are limited by their analog nature, preventing real-time data sharing and historical recordkeeping, and lack integration with telemetry data and remote access.

Innovation Solution

Implementing Near Field Communication (NFC) or Radio Frequency Identification (RFID) operations in Land Mobile Radios (LMRs) to facilitate check-in/check-out processes, sensor data collection, and secure access to structures, with information transmission over packet-switched LMR infrastructure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If analog tracking methods (hook and loop fasteners) are used, then personnel accountability tracking is achieved, but real-time data sharing and historical recordkeeping are prevented

Engineering Contradiction:
Improvepersonnel accountability dataVSAvoidtracking system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical hook and loop fastener system with an electronic NFC/RFID-based tracking system integrated into LMR devices. This substitution enables digital data capture, real-time sharing, and historical recordkeeping while maintaining personnel accountability tracking functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces NFC/RFID tags and readers as intermediary components between personnel and the central server. These intermediaries enable automatic data exchange and transmission of personnel accountability information through the packet-switched LMR infrastructure, eliminating the need for manual analog tracking.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If NFC/RFID operations are implemented in LMRs, then real-time tracking and historical recordkeeping are enabled, but device complexity increases

Engineering Contradiction:
Improvepersonnel accountability trackingVSAvoidLMR system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates NFC/RFID functionality into existing LMR devices, which already serve as primary communication tools for first responders. This multi-functionality approach allows the LMR to handle both traditional radio communications and modern NFC/RFID operations, reducing the need for separate dedicated tracking devices and minimizing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically performs check-in/check-out operations and data transmission without requiring manual intervention from personnel. The LMR device autonomously communicates with NFC/RFID tags and transmits accountability data through the packet-switched infrastructure, reducing operational complexity while improving reliability.

Inventive Principle:
Principle #25Self-service

3Productivity

If manual check-in/check-out processes are used, then personnel tracking is achieved, but time consumption and efficiency are increased

Engineering Contradiction:
Improveincident management efficiencyVSAvoidcheck-in/check-out processing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements automatic check-in functionality where personnel are pre-configured with NFC/RFID tags in their LMR devices. Upon entering a geographic fence or approaching a reader, the system automatically performs check-in operations and transmits data to the central server, eliminating manual registration steps and reducing time loss during incident response.

Inventive Principle:
Principle #10Preliminary action

AI summary

Systems and methods for operating a Land Mobile Radio ("LMR"). The methods comprise: performing Near Field Communication ("NFC") or Radio Frequency Identification ("RFID") operations by the LMR and an external device; and sending from the LMR or receiving at the LMR information associated with the NFC or RFID operations via the packet switched LMR infrastructure. The information associated with the NFC or RFID operations includes, but is not limited to, check-in information for an incident event, check-out information for an incident, sensor data, authentication keys, verification keys, access codes, and LMR configuration (e.g. personality) information, LMR software code, and/or LMR firmware.
