NWO Cardiac SDK

Dual-Modal Cardiac Biometrics Platform

WiFi CSI (contactless) + BLE Wearables (identity-grade) for robust biometric verification.

---

🎯 Key Insight

WiFi CSI reliably extracts heart rate and presence but NOT identity-grade cardiac morphology. BLE wearables (Apple Watch, Polar H10) provide the missing identity layer.

Together they create a system that is:

• ✅ Hard to spoof (need both signals)
• ✅ Privacy-preserving (contactless until identity needed)
• ✅ Continuous (CSI always on, wearable periodic)
• ✅ Multi-market (4 independent verticals)

🚀 Quick Start

pip install nwo-cardiac

from nwo_cardiac import CSISensor, BLECardiac, CardiacFusion

# Initialize sensors
csi = CSISensor(interface="wlan0", channel=36)
watch = BLECardiac.connect_apple_watch("AA:BB:CC:DD:EE:FF")

# Create fusion engine
fusion = CardiacFusion(csi, watch)

# Enroll identity
fusion.enroll_identity("user_123")

# Verify
result = fusion.verify_identity("user_123")
print(f"Verified: {result.identity_verified}, Confidence: {result.confidence}")

📦 Four Independent Markets

1. Access Control

from nwo_cardiac import SecureEntry

entry = SecureEntry(
    entry_id="main_door",
    csi_enabled=True,
    wearable_required=True
)

# Walk up, get verified, door opens
result = entry.process_entry_request(
    csi_sensor=csi,
    wearable_connector=watch
)

2. Wellness & Fitness

from nwo_cardiac import FitnessTracker

tracker = FitnessTracker(gym_id="goldsgym_downtown")

# Automatic check-in
tracker.auto_checkin("member_456", csi, watch)

# Get workout summary
summary = tracker.checkout("member_456")

3. Clinical Research

from nwo_cardiac import RemoteMonitor

monitor = RemoteMonitor(
    patient_id="patient_789",
    diagnosis="afib_history",
    csi_enabled=True
)

# Detect anomalies
alert = monitor.detect_anomaly(
    anomaly_types=["arrhythmia", "bradycardia"]
)

4. Robotics (NWO Integration)

from nwo_cardiac import HumanAwareRobot

robot = HumanAwareRobot(robot_id="arm_01")

# Assess human state
state = robot.assess_human_state("work_area", csi, watch)

# Adapt behavior
if state.stress_level > 0.7:
    robot.pause_operation()
