The user scenario below demonstrates the one of many possible circumstances and the benefit of Lifetch for preventing loss of human lives, which is the objective of the system.

On a beautiful Sunday John decided to go hiking with his friend, Mike. At the entrance of the National Park near his town they rented one ICU. Mike also had a cell phone. After a short time they passed a Relay, where the ICU downloaded a general map of the park area.

After five hours the ICU started beeping, receiving the message through Mike's phone data transmission line. A warning message arrived informing him of an impending sudden change in weather conditions. He asked through the ICU for the nearest shelter. After receiving a detailed map they headed towards the shelter. Temperature started to drop, a strong wind broke out, and a downpour began. Suddenly, John slipped on a wet rock and tumbled down the steep slope, with the ICU in his backpack. He was knocked unconscious during the fall. Mike yelled for help, also tried to use his cell phone, but there was no response. The situation became helpless, but after a little over twenty minutes Mike heard the sound of a rescue helicopter.

They were found and John was taken into hospital. When John regained consciousness they learned that, were it not for the ICU, they would not be found at all. The phone could not function because the base station was damaged during the storm. The ICU detected John's tumbling thanks to the built-in sensors and used radio transceiver to send the message to the Command Center by the chain of ICUs belonging to other hikers. The operator immediately dispatched a rescue team. The whole adventure found its happy end.
