Silent Vigilance.
Multi-Modal AI
Child Protection.

Guardian Pulse is a non-intrusive wearable early-warning platform designed to protect vulnerable children. Combining real-time Heart Rate analytics with on-device Neural Audio Event Classification, it eliminates the burden of self-reporting while delivering a remarkable 3.2% False Positive Rate.

Engineered for Reliability

Why Single-Sensor Solutions Fail & How Sensor Fusion Wins

Traditional safeguarding wearables trigger excessive false alarms from innocent child activities (running, playing) or ambient noises (TV, traffic), leading to alert fatigue.

Dual-Stream Fusion Engine

Sustained Heart Rate anomaly calculation combined with temporal co-occurrence of audio distress patterns. Alerts fire only when physiological distress and acoustics align.

False Alarm Reduction -90.6%

Sensifai Edge Neural AER

Proprietary lightweight Multi-Layer Perceptron (MLP) trained on ESC-50 and RAVDESS. Extracts MFCC features directly in pure Kotlin—running locally without heavy TensorFlow dependencies.

Model Size <150 KB

Silent Anti-Tamper Protection

Continuous optical and proximity skin-contact checks detect unauthorized unlatching. Dispatches a silent, prioritized notification without escalating dangerous household tension.

Tamper Response Time 5.0s Debounce

Automated 3-Tier Escalation Protocol (Child Safeguarding Standard)

TIER 1 • IMMEDIATE
Safe Adult Notification

Direct encrypted dispatch with one-tap acknowledgment button (ACK).

TIER 2 • DE-ESCALATION
Cognitive Interrupt

Calm intervention notice delivered: "Elevated stress detected. Please take a moment to step away."

TIER 3 • ESCALATION
Protection Officer Intervention

If unacknowledged within configurable timeout, automatic escalation to assigned Case Officer.

Empirical Test Methodology

Validated Across 125 Controlled Test Scenarios

Evaluated in July 2026 across Samsung Galaxy A23 (Android 12) and Xiaomi Redmi 10 (Android 11) devices under rigorous, acted laboratory simulations.

Distress Detection Recall 99.2% (124/125)
Alert Precision 96.9% (124/128)
False Positive Rate 3.2% (vs 34% Single HR)
Active Battery Consumption ≤ 3.8% / hour
Total Memory Footprint < 60 MB RAM

Empirical Confusion Matrix N = 125 Acted Scenarios

ACTUAL CONDITION ALERT TRIGGERED NO ALERT
Distress Scenario (Positive) 124 (True Positive) 1 (False Negative)
Normal / Play (Negative) 4 (False Positive) 121 (True Negative)
