SILERT: AUTOMATED INVOLUNTARY SILENT ALERT SELF-DEFENSE SYSTEM

摘要

Self-defense is a countermeasure that involves defending the health and well-being of oneself from harm by others including humans, animals etc. Physical self-defense is the use of physical force to counter an immediate threat of violence. Such force can be either armed or unarmed. In either case, the chances of success depend on a large number of parameters, related to the severity of the threat on one hand, but also on the mental and physical preparedness of the defender. Self-defense may be by way of using martial arts, licensed weapons, hand held personal alarms that generate high pitch sounds to attract passerby etc. The defender may either be strong or may be weak being elderly, disabled, child, sick etc. If the defender is strong enough to react swiftly while in danger then the above mentioned mechanisms work well. However if the defender is weak or the situation happens so abruptly that the defender may not get enough time to use the defense mechanism, then protection becomes a complete failure. With the rising crimes in every country where children, females, elderly persons become victims of human threat of violence, this invention aims at creation of a novel automated involuntary alert system that operates involuntarily by taking into consideration the biological signals of a human being without the knowledge of the victim. This device is named SiLERT (Automated Involuntary Silent Alert Self- Defense System). It is a small device that may be worn by the victim whenever he or she goes out to potentially dangerous areas. The device monitors the human heart beat rate as well as electrical activities of the brain to detect whether the person is in a fearful condition or in danger. As soon as fearful condition is detected the system automatically dials and sends emergency alert information including the location of the user via GPS to some predefined mobile numbers silently without the knowledge of the victim and attacker. On receiving the emergency information, proper safeguard of the victim is guaranteed. This device promises freedom of movement of common men, local population and above all assures the nation a safe surrounding.
