VCT EDGEGUARD
Smart Harness Compliance Detection in Real Time.
VCT EdgeGuard is a smart safety harness concept designed to monitor proper harness usage in real time using Ultra-Wideband (UWB) and inertial measurement technologies. It detects unsafe wearing practices, issues immediate on-site alerts through the VCT InSite helmet, and sends summarized harness status to the platform via LoRa.
FROM HARNESS POSITION TO IMMEDIATE SAFETY ACTION.
Sense
UWB + IMU sensor nodes collect spatial and tilt data from the harness.
Model
Sensor-to-sensor distances and IMU data reconstruct the harness shape in 3D.
Detect
The current harness configuration is compared against known correct and incorrect wearing patterns.
Alert
If an unsafe condition is detected, the VCT InSite helmet issues an immediate local alert.

6 SENSOR POINTS.ONE 3D HARNESS MODEL.
A real-time spatial model of how the harness is being worn.
- Left Hook
- Right Hook
- Waist Belt
- Left Thigh Strap
- Right Thigh Strap
- Upper Back D-Ring
Relative positions between these 6 points are used to reconstruct the 3D harness geometry and detect compliance.

ALERTS WHERE THEY MATTER MOST — ON SITE.
The central reader in the VCT InSite helmet evaluates harness condition and triggers alerts through the helmet's buzzer or speaker.
All alerts are issued locally, independent of cloud processing.
Harness secure. Proceed.

MINIMAL DATA. CLEAR OPERATIONAL VISIBILITY.
A summary of harness status is transmitted every 60 seconds via LoRa, minimizing data volume and conserving battery.
BUILT FOR THE FIELD.
Non-Invasive
No interference with harness integrity.
Scalable
Modular, low-power tag design.
No Infrastructure Needed
The helmet handles processing.
On-Device Alerts
Fully on-device alerts with minimal LoRa transmission.
Reliable Detection
Detection of correct and incorrect harness usage patterns.
