1. System Architecture & Principles

SonitorOne Vector operates as an edge-native spatial intelligence layer. When ultrasound microphones are temporarily obstructed or tags traverse uninstrumented corridors, Vector ingests the tag's 802.11b beacon telemetry and constructs a Bayesian RF Co-Visibility Mesh against the 9,189 active ultrasound tags across the facility.

2. Algorithmic Formulation

Each fallback tag vector is evaluated using a composite scoring function:

Score(Tag, Room) = 50.0 * S_primary + 30.0 * S_jaccard + 40.0 * S_rssi_proximity

Where:
• S_primary = 1.0 if Associated AP == Dominant Room Listener
• S_jaccard = |Shared APs| / |Union APs|
• S_rssi_proximity = exp(-RMSE_dBm / 12.0)
• Certainty % = Softmax(Score, Temperature=15.0)

3. Inbound Server Telemetry Webhook

On-premise Sonitor Sense servers push live tag updates via HTTPS POST:

POST /api/v1/telemetry/ingest
Header: source-id: sonitor-telemetry-feed
Payload: { "installation_id": 1, "tags": [ ... ] }

4. Sonitor Sense™ Hardware Specification & RTLS Infrastructure Reference

Sonitor Sense combines proprietary 40 kHz Ultrasound Low Energy (ULE) with standard Wi-Fi backhaul. Because ultrasound waves cannot penetrate drywall, glass, or solid partitions, the acoustic signal guarantees 100% room, bay, and chair precision.

Location Transmitter & Gateway

Sonitor Sense™ B200 Series

Ceiling & wall-mounted ultrasound acoustic beacons. Deployed as LT BA (Bay Level), LT CR (Corridor/Room Level), and LT LF (Low-Frequency Chokepoint). Transmits unique USID pulses at 40 kHz.

SmartTag™ Mini (Tag J)

1 or 2 Buttons (J221 / J241 / J251)

Ultra-compact form factor for patient wristbands, pediatric tracking, and small clinical assets. Configurable with 1 or 2 buttons, tamper-evident cut-band (J251), and water-resistant IP67 casing.

SmartTag™ (Tag H)

2 Buttons • High-Value Asset Tag

Multi-year battery life for IV pumps, crash carts, ventilators, and telemetry monitors. Dual tactile call buttons, multi-axis accelerometer, and multi-mode 40 kHz acoustic receiver.

Sense™ SmartBadge™

Staff ID & Duress Call

Wearable staff safety badge with instant emergency pull-cord duress, dual side buttons, and acoustic sub-second location updates during high-risk security events.
