Solution Overview

Problem

Existing first responder systems overwhelm users with duplicative alarms and notifications, leading to information overload and potential failure to notice critical alerts in dangerous environments.

Innovation Solution

Implementing algorithms and artificial intelligence to prioritize alerts based on criticality, using visual, audible, and haptic modalities to present unambiguous displays on personal protective equipment (PPE), and enabling communication between PPE and accessory devices through wired and wireless connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple alarms and notifications are provided to ensure comprehensive safety monitoring, then the completeness of safety information is improved, but information overload and user confusion increase

Engineering Contradiction:
Improvesafety monitoring completenessVSAvoidinformation overload
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent segments alarms into different priority levels (critical, high, medium, low) and uses distinct notification modalities for each level. Critical alarms use immediate audible and visual notifications, while lower priority alarms use less intrusive methods. This segmentation allows comprehensive safety monitoring while preventing information overload by organizing notifications hierarchically.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different notification qualities to different types of alarms based on their criticality. Critical safety alarms receive prominent, immediate notification through multiple modalities (audible, visual), while non-critical notifications use subdued methods. This local quality approach ensures that important safety information stands out while reducing the harmful effect of overall information overload.

Inventive Principle:
Principle #3Local quality

2Reliability

If multiple alarm modalities (visual, audible, haptic) are used to ensure critical alerts are noticed, then the reliability of alert delivery is improved, but the complexity of the system increases

Engineering Contradiction:
Improvealert delivery reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent dynamically selects and combines notification modalities based on the priority level of each alarm and the current operational context. The system adapts the notification approach in real-time, using more intensive modalities for critical alarms and simpler ones for non-critical notifications. This dynamic approach ensures reliable alert delivery for critical safety issues while managing system complexity through context-aware adaptation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements a universal notification framework that handles multiple types of alarms through a common prioritization and delivery mechanism. The same processing logic manages visual, audible, and haptic notifications across different alarm types, reducing overall system complexity despite the multi-modal approach. This universal framework ensures reliable critical alert delivery while avoiding the need for separate handling mechanisms for each notification type.

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

3Reliability

If regulatory certification alarms are included to meet safety standards, then compliance with safety regulations is improved, but the quantity of duplicative alarms increases

Engineering Contradiction:
Improveregulatory complianceVSAvoidnumber of alarms
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges regulatory certification alarms with the prioritization framework by integrating them into the existing priority levels. Instead of treating regulatory alarms as separate, duplicative notifications, the system combines them with operational alarms of equivalent criticality. This merging maintains regulatory compliance while reducing the total number of alarms by eliminating redundancy through unified notification handling.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A personal protective equipment (PPE) associated with a first responder and including processing circuitry is provided. The processing circuitry is configured to store a prioritization mapping, receive a first alert, determine a first prioritization parameter for the first alert based on the prioritization mapping, determine a user interface modality for the first alert based on the first prioritization parameter, and communicate the first alert to the first responder via the user interface modality.
