Now a day's people feel insecure due to increase in the crime rate and accidents. Technology can be used at a greater scale to reduce these and with this inspiration we are proposing a system that can provide instant help in a better and faster way. The most common applications we have are panic alarm/ danger alert, requiring user to take actions to keep themselves safe. Practitioners saw some value of information and evidence gathering functions but, had safety concerns relating to their use by domestic violence victims still living with the perpetrator. The proposed system is using GPS which will take the location of the user from Google map. The main concept would be sending a voice message and a message template to the selected contacts and emergency numbers when in danger. Enhancement from the earlier systems we are providing user tracking when he/she is in a position that he cannot alert others.

Abstract-In this Paper, aim is to achieve a narrow bandwidth filter. For that coupled line filter is good choice. Coupled-line filter is designed on microstrip for its compactness. Microstrip dimension are calculated using synthesis technique formula. A Coupled-Line Microstrip Filter is designed for centre frequency 2.4GHz and it is made up of FR-4 material having permittivity Єr=4.4. Coupled line filter demonstrate the fourth order of the Chebyshev elements and its response corresponds to bandpass filter. The geometry is analysed by using Computer Stimulation Techniques (CST) software.
