A Multiply Function Device for Self Protection (Especially for Females)

Abstract:

The design for multi-function self defense device can strengthen the protection for females, also provide automatic alarm and trace the location of the device (user).Traditional defense devices can not combine defense function with automatic alarm at the same time. GPS system, infrared communication and single chip microcomputer were used .The device can be used when people go out alone. It can spray pungent water, emit strong light, call the user’s relatives as well as send out current location massage in a secret way. The implement of the device demonstrate that the device could be employed satisfactorily when the users need effective help in emergency.
