Using a so-called Time of Flight sensor with skeleton detection attached to the ceiling, any person who has fallen and is lying on the floor can be detected. This function is particularly important for the sense of security of the elderly or people with health restrictions.  A finger distress button is not always used and therefore does not provide reliable information. When a person cannot get up from the floor, an alarm chain is activated. It is planned to work together with an emergency service, who would take on the 24/7 emergency care requirements.
