The population alarm systems do not represent a new concept. Since hundreds of years ago the man used either smoke signals generated from certain upper locations, visible from long distance, getting through acoustic systems placed on high buildings, until now when mass-media channels extended the possibilities by the television and radio. However, either one of those mentioned above requested the individual to be located at the alarming moment in the area of action of the alarm. Otherwise, the message has no efficiency. This limitation is currently solved by additional communication channels such as the internet and the mobile networks. Messages are now able to be sent to the mobile screen, and the user can reply to messages either by using the short message service (SMS) or by emailing to someone, to a server, to a center. From the general pattern of alarming the population on certain events, the medical applications represent a very important field. Messages are sent from the patient to a central medical center and back to the patient. This paper focuses on the value that virtual tools developed with LabVIEW brings to us.
