Smart band for autonumously recognizing crisis situation and automatically requesting rescue on the basis of sound and motion patterns

A smart band apparatus for autonomously recognizing a crisis situation and automatically requesting rescue based on sound and motion patterns, the smart band apparatus comprising:

• a microphone that collects sound patterns of a scream or a sudden sound in a crisis situation;
• an audio signal pattern library that stores keyword sound patterns, which are generated in memory in each crisis situation;
• acceleration and inertia sensors installed that sense a movement of a wearer;
• a motion analysis memory that stores a waveform determination algorithm for collecting signals inputted from the acceleration and inertia sensors for a predetermined time period, analyzes a motion signal pattern, and categorizes the motion signal pattern as impulse, pulsation or steady;
• a crisis situation recognition processor that derives a crisis situation code of any one of terror, sexual violence, a falling accident, a natural disaster, and a sexual harassment by analyzing a motion waveform and a sound pattern;
• a microcontroller that automatically transmits a request for rescue to a rescue team or a guardian programmed in advance, together with the derived emergency crisis situation code, a GPS position and personal information of the wearer, said microcontroller cooperative with said microphone, said audio recognition library, said acceleration and inertia sensors, said motion analysis memory and said crisis situation recognition processor;
• a Bluetooth communication interface unit cooperative with microcontroller;
• a smart phone monitoring circuit that monitors a pairing smart phone by said Bluetooth communication interface unit;
• and
• a switch that records sexual harassment speeches or manually initiating a crisis situation when the wearer is sexually harassed.
