xCoupler/C™
Cargo integrity monitor

Applications
- Detect door, floor, and wall breaches (DHS SAFECON)
- Detect changes in cargo locations / humans in container (DHS       SAFECON)
- Detect temperature levels and changes (Food safety)
- Detect shocks (Cargo damage)

Features
- Air-coupled acoustic sensor pings doors and cargo to detect changes
- Solid-coupled acoustic sensors monitor floor and wall integrity
- Temperature sensor samples ambient temperatures
- Accelerometer monitors sudden changes in direction (g-force)
- Encrypted XBee/2400 wireless networking links to StrongBox to report       heartbeat and monitored events.

xCoupler/G™
Genset and fuel monitor

Applications
- Monitor and report genset fuel levels
- Monitor and report genset status

Features
- Solid-coupled acoustic sensor pings fuel tank to determine levels
- Wired genset harness detects operational parameters, including       external power voltage / current, genset operating status, and       genset power output.
- Theft of genset is indicated by disconnection of monitoring harness or       moving out or range of StrongBox.
- Encrypted xBee/2400 wireless networking links to StrongBox to report       monitored parameters.

xCoupler/R™
