Functional DiagramClosed Loop Readiness

Step 1: User requests a

mobile device

Step 2: Server chooses device to exercise; sends

wireless query for readiness

Step 3: Device is activated through wireless link; scans bar code, checks memory and reports back to server

Step 4: Server receives readiness

response

Step 5: Server sends release command

Step 6: Mobile computer receives release command; activates release

Location based Man-Down service solutions ( Motorola Internal Paper, proprietary) May 9, 2008“Organizations seek an improved system that will track personnel throughout their facilities and provide on-body sensing to help preserve worker health and safety by providing alerts when risks are detected. The capability to monitor environmental risks such as toxic gases, and to provide an indication of biological function such as prolonged worker inactivity are considered valuable and an important consideration.” Authors: Babin, T., Candelaria, J., Levenson, S., Lewis, J., May, P., Mastroianni, S., Tungare, A. – Motorola Labs Eriksen, L., Kanagala, S., Roslak, T., Slavin, J., Yamanishi, G. – Enterprise Mobility Business
