From a17b630c021f32c53959d06d5bb72334eaa4214a Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 13 Jan 2026 17:24:50 +0000 Subject: [PATCH] feat: Add wifi-densepose-mat disaster detection module Implements WiFi-Mat (Mass Casualty Assessment Tool) for detecting and localizing survivors trapped in rubble, earthquakes, and natural disasters. Architecture: - Domain-Driven Design with bounded contexts (Detection, Localization, Alerting) - Modular Rust crate integrating with existing wifi-densepose-* crates - Event-driven architecture for audit trails and distributed deployments Features: - Breathing pattern detection from CSI amplitude variations - Heartbeat detection using micro-Doppler analysis - Movement classification (gross, fine, tremor, periodic) - START protocol-compatible triage classification - 3D position estimation via triangulation and depth estimation - Real-time alert generation with priority escalation
