For seniors in general, falls can result result in broken hips or other serious injuries. For seniors living alone, however, there's also a good chance that they could end up lying on the floor for up to several hours before anyone else knows what's happened. User-triggered radio devices such as Life Alert are helpful up to a point, although they're not much good if the user isn't carrying them at the time, or if they get knocked unconscious. That's why a group of German companies are developing the automatic safe@home system.
