- 9. GPS and DISPATCH® Swiss cheese metaphor applied to proximity GPS+FMS • Distance and path based • Configurable nominal latency • MovingMap operator guidance and smart display • Onboard interfaces and DISPATCH® provide context to additional layers
- 10. RF Beaconing layer Swiss cheese metaphor applied to proximity GPS+FMS RF Beacons • Independent from wireless infrastructure • Low cost light vehicle transceivers and personnel devices • Primarily for low speed, congested areas • 2 configurable detection zones – Alarm and Warning • Emergency broadcast capability
- 11. Camera Layer Swiss cheese metaphor applied to proximity GPS+FMS RF Beacons Cameras • Context based camera switching • Single screen shared with FMS • Continuous recording, 2hr loop
- 12. Forward and Rear Long Range Radar Swiss cheese metaphor applied to proximity GPS+FMS RF Beacons Cameras • Near obstacle detection when stopped • Far obstacle detection travelling in collision risk areas • Potential for changing radar sensitivity and mask to location requirements and activity Radar
- 13. Human Operator Swiss cheese metaphor applied to proximity GPS+FMS RF Beacons Cameras Human • Reduce nuisance alarms to avoid “tuning out” • Single screen to limit information load • Fatigue Risk Management to reduce risk of low alertness Radar

- 20. Advantages of Integration » Fleet Management System has global context • Vehicle status: Ready / Down / Standby / Delay • Vehicle activity: Loading / Dumping / Hauling / Fueling / Queuing • Vehicle location: Road geometry, congested, dangerous areas • Vehicle path: Assignment, road network • Other known vehicles in neighborhood » Onboard System knows local equipment state • Speed, heading, engine running, idle, full power, off • Payload, tray up / down • Vehicle gear selection, park release, etc. with the DISPATCH® Mine Management System
- 21. Advantages of Integration » RF and Radar measure local proximity • Detect presence irrespective of context • Context used to reduce nuisance alarms • Turn RF proximity off above certain speed • Turn Radar off below certain speed • Turn front Radar on at low power when stopped • and many more » Single screen interface with operator • Screen can switch views according to context • Single screen can merge camera, sensor, local and global data with the DISPATCH® Mine Management System
