Abstract a girl, women, and the word “she” itself indicates the generation of new humanity. the new age of modern society. if we see nowadays the girl harassment cases were becoming more and more so our aim is to reduce those cases for which we are making the device called “antirape techno gun for women protection” the anti rape gadget. the anti-rape weapon uses a wireless control system equipped with an electronic weapon and a receiver. the device uses a three step wireless alarm which is set up in the police control room. the device can be activated when a girl senses trouble. using radio waves, the device sends the distress signals, thus alerting the police control room. the device uses embedded technology. the size of device can also be reduced by using very large scale integrated (vlsi) design. antirape device present invention relates to an improved antirape device. more particularly, the invention relates to a device which is adapted to be inserted into the vaginal cavity of a human female for protection against a rapist. rape is a crime which everyone is aware of and feels the is repugnant to society. it is a crime which is and has been prevalent throughout society. through the years, various measures have been suggested for preventing a rape. an obvious means of preventing rape by the use of a physical force greater than that possessed by the attacker has not met with success. thus, weapons e.g. knives, guns, aerosol sprays and various other types of physical force can be used by the female. unfortunately, the male attacker is often stronger which, together with the element of surprise, will prevent the victim from using the weapon. self-defense techniques have also been found to be decent. this is not only because they require a high level of skill and physical conditioning to be effective but also they require a violent mental attitude to effectively repulse an attacker. while various types of whistles and alarms that are intended to summons assistance are available on the market and can be effective, they are not the entire answer to the problem .this is because of the element of surprise and the lack of time within which to use the whistle or alarm project objective in today’s world the position of india in list of rape attempt is going on top position, now we are ashamed to say “incredible india” as the rape attempt is rapidly increasing day by day. we have decided to make a device named as “antirape techno gun for women protection” which will provide a security to women. this project idea is came from delhi gang rape where the innocent girl become a rape victim in bus while traveling with a friend and the rape victim a women reporter traveling in a train and there are so many cases of such victims. we have decided to make such a device that would stop sexual assault on women’s and provide better security because at every time it is impossible to be with someone who will protect them so for that they only should protect themselves from unknown persons. the latest estimate suggests that a new case of rape is reported every 22 minutes in india. after doing a lot of research in this direction we decided to make a device that will not only helps us to find that person but also secure that women problem defination in today’s world the position of india in list of rape attempt is going on top position, we have decided to make a device named as “antirape techno gun for women protection” which will provide a security to women. we have decided to make such a device that would stop sexual assault on women’s and provide better security because at every time it is impossible to be with someone who will protect them so for that they only should protect themselves from unknown persons. this device is based on principle of wireless communication in which we have used the devices such as transmitter, receiver, global positioning system (gps) a tracking system, global system for mobile (gsm) an identity module, alarm system, battery storage, and electronic shock gun (teaser gun). the main purpose to make this device is to help women’s and she can help herself without depending on others. working of antirape device the device consist of microcontroller which is performing the programming part with the various programs which is having two switches (s1 & s2) and it is connected to the transmitter which is consist of global positioning system (gps) which is used to provide extremely accurate location. information for mobile objects and people. gps consists of a network of 24 satellites in six different 12-hour orbital paths spaced so that at least five are in view from every point on the globe. the satellites continuously transmit military and civilian navigation data on two l band frequencies. it is also consist of global system for mobile (gsm) which is a combination of tdma and fdma schemes. the microcontroller is also connected to electronic gun (teaser) which is used to provide the high voltage through its terminal and are used for incapacitating aggressive persons by disrupting. superficial muscle functions through administering electric shocks and also connected to alarm circuit and to receiver section. the propose circuit of “antirape techno gun” is given below with the various components and various functioning parts. advantages since the purpose of making the antirape techno gun is to provide a better life to a society and providing security to women. there are many advantages regarding to this device and which are very necessary for the betterment related to girl or women. this device is not only used for women security but also used as to detection of small kids. i. the anti rape device can also be used as a human detector as to detect the small kids and others. ii. working women in late night shift like in call center girl’s can use this device for their protection from unknown persons. iii. in metro cities like mumbai, delhi, bangalore and others cities this device will be very helpful to those students and working women’s to protect themselves from unknown persons. disadvantage this is impossible to say that anything is not having any disadvantages or a 100% efficient in his field. in this device we are using an electronic gun which is using a principle of high storage voltage capacity and the energy for this is stored in a battery which is always chargeable. the use of electronic gun may be harmful. application there are many applications of this anti rape gadget as it is working on principle of wireless communication which is used to carry information in form of discrete signals though wirelessly with any electrical conductors or wires. i. when a woman walking alone or in dark night shift, if there are someone being closely to her or following her, she can pull the trigger. then the alarms will sound the alarm and the help is provided ii. when going for shopping, child could take a alarm and in case of being separated, which can sound the fire alarm, and avoid missing of small kids. iii. the old man with acute serious disease (such as coronary heart disease, etc.), carry (or night in bedside suspension) this cheap personal alarm, if he cannot speak about his case, then sound the fire alarm could save lives conclusion i. this “antirape techno gun for women protection” device is used for security of women as well as it decreases the rape and harassment cases in india.
