“WOMEN SAFETY WEARABLE DEVICE”

in the name of KARUNYA INSTITUTE OF TECHNOLGY AND SCIENCES an Indian National having address at Karunya Institute of Technology And Sciences, Karunya Nagar, Coimbatore - 641114, Tamilnadu , India.

The following specification particularly describes the invention and the manner in which it is to be performed
FIELD OF THE INVENTION:
The present invention relates to a safety device. More particularly the present invention relates to a wearable women safety device for self defense.

BACKGROUND OF THE INVENTION:
As time advances, there are new inventions and technology is taking over everything in our day to day life. The society we live has advanced to a digital world but there is no safety for women in this wide world. In today’s world there is no safety for women to walk alone on the streets at night. Even though India is a democratic country, there exists some lack in safety of women in certain parts of India. Hence it becomes the duty of every woman to keep her safe. Women are mostly not physically stronger than men.
The economic and cultural paradigm shift has made it mandatory for women to work. To increase their job opportunities, women all over the world are educated and work in standards equal to their male counterparts. Even though there has been an increase in education and work opportunities, the safety of women is still an issue. Hence in recent times there has been a lot of web based and device based security proposals.
The One Touch Alarm System for women safety uses global system for mobile communication (GSM) for identifying the location of the victim. Once triggered, the system is immediately tracked and the location of the woman in distress is identified using GSM. Also emergency messages are sent to selected contacts and to the police control room. The emergency switch once activated triggers the device into performing all the above actions. In this system, the victim may suffer physical abuse since there is no self defence mechanism to protect them.
In all the available women based safety system, the victim has to press an emergency button, which may not be possible under emergency circumstances. The parent or guardian of the victim has to send a message to receive the location of the victim. This may lead to loss of time which can further lead to loss of life. The mobile application for finding friends needs an application to be installed in the smart phone of all in the group to keep track of each other. In all these applications the victim can be saved only if they trigger the initial action, which may not be possible in such drastic situations. So there exists a need in the state of art to develop a novel safety device for women which can be triggered automatically without any human triggering in such extreme situations.

OBJECT OF THE INVENTION:
The main object of the present invention is to fabricate a novel wearable women safety device for self defense.
Another object of the present invention is to fabricate a wearable women safety device comprises of a circuitry which encompassing location tracking module, notification module, a detection module, a characterized self-defense module and an Arduino kit.
Yet another object of the present invention is to fabricate a wearable women safety device which can provide initial protection as well send location intimation and call emergency services simultaneously without any delay to prevent trauma or loss of life.
Further object of the present invention is to employ the developed device to protect women themselves from strangers when they are attacked and to defend themselves.

DETAILED DESCRIPTION OF THE INVENTION:
The present invention discloses a wearable women safety device to protect women themselves from strangers when they are attacked and also for their self defense.
The device of the present invention can help every woman protect themselves from strangers and when they are attacked, they can defend themselves. The main aim of the present invention is to design a self-defense mechanism in the form of a safety wearable device like a backpack. Pressure sensors are used in the backpack and in arm of the woman. So, when a stranger tries to attack a woman by holding onto the hands, the pressure sensor gets triggered and high voltage electricity generator will produce a high voltage which will disarm the attacker temporarily. A high frequency alarm will also ensue and alert the surrounding people. At the same time through a GSM module, an alert message will be sent to her emergency contacts. Thus the self-defense mechanism works and assists the woman to protect and defend herself.
A self-defensewomen safety system is developed which triggered automatically under emergency situationsand sends the location of the victim to the concerned authorities and emergency services. The device will also play a pre-recorded message using a speech circuit to alert the surroundings. The device is proposed to be deployed as an android application. Its basic functionality is to send an SOS message, record audio and video of the whole incident as evidence. The present system can also detect hidden cameras using a radio frequency, which collects and detects electromagnetic waves that are emitted from the spy camera. Almost every existing hand held safety device for women requires human interference for activating the device such as pressing the button or shake the device etc. after sensing the danger. However, the present device relies on fingerprint-based method of connectivity to the device. The idea is that if there is no fingerprint confirmation to stop the triggering of the IoT based device for half a minute, then it will mechanically alert nearby people and send intimation to the police. The present work of this project is mainly to equip a woman who can defend herself when she is in danger. This innovative device makes sure that a woman can defend by using the proposed device which can be placed in the backpack or handbag. There exist pressure sensors which trigger once an attacker touches or roughly holds a women’s hand. There exists a basic threshold value beyond which it is identified as threat and the alarm is triggered and a high voltage generator produces an electric shock which temporarily stops the attacker. At the same time, the high frequency buzzer issues an alarm which alerts the nearby people. The global positioning system (GPS) tracks and sends the location of the woman when the GSM module sends an alert message to the registered contacts.
The novelty of this mechanism is that it is small and battery operated which can be fixed the person itself. The high pressure that is used to mainly harm a person will automatically trigger safety precautions and help to save a life.
Fig.1 shows the basic block diagram structure of the women safety device. This device consists of the location tracking module [101], notification module [102], detection module which includes the pressure sensor [103] and pulse sensor [104] and the self-defense mechanism which includes the alarm buzzer [105] and the high voltage generator [106]. All these modules ate controlled and perform action with the program triggered in the Arduino kit [107].
The location tracking module [101] is used for tracking the movements of the woman. The global positioning system of the device is programmed to be initiated once the pressure sensors, record a pressure value which crosses the threshold value. The information like time, location and user name will be stored in the cloud server for future reference. This location will be sent across to the nearby police stations, parents and all emergency numbers.
The notification module [102] utilizes the GSM service of the smart phone to send alert messages to the nearby police stations, parents and all emergency numbers. Even this information are stored in the cloud server with timestamp and user details.
The detection module holds the pressure sensor module [103] and the heart rate sensor module [104]. The pressure sensor [103] collects the information of the pressure applied on the user’s arm and once it registers a value about the threshold, a threat message is sent though the Arduino kit which will immediately activate the alarm [105], high voltage generator [106], notification [102] and location tracking [101] modules. Similarly, the heart rate sensor module [104] will be regularly reading the pulse rate of the user. Once the pulse rate exceeds the minimum or if there is a sudden spike in the pulse rate, immediately it triggers the protection mechanism like the alarm [105], high voltage generator [106], notification [102] and location tracking [101] modules.
In the self-defense module, the alarm buzzer [105] and high voltage generator [106] to generate the shock are present. Since all are interconnected using the Arduino kit, there is a complete flow of data. The alarm is activated when there is a detection of high pressure force beyond the threshold value on the self of the user along with the increase in heartbeat rate.
The high voltage generator also gets triggered during the detection of the high pressure force beyond the threshold value along with an increased pulse rate of the user. It sends out a shock wave to the attacker automatically. This prevents the attacker and discourages the attacker to stop further possible violence on the user.
Fig. 2 shows the circuit of the safety device. The Arduino Uno kit [201] is a microcontroller system based on the ATmega328. The total number of input and output pins in the Arduino Uno kit is 20 in count. Out of the 20 pins, 6 can be used as analog inputs and 6 as PWM outputs. It also has a 16 MHz resonator, a power jack, a USB connection, a reset button and an in-circuit system programming (ICSP) header. All the attachments required to support the microcontroller along with a USB cable to power it with a battery or an AC-to-DC adapter. The alarm buzzer [202] works with high frequencies to emit resonances. The human ears can distinguish a sound of low pitch or high pitch. This characteristic is related to the amount of cycles (vibrations) of a sound wave in one second and its unit is Hertz (Hz). The pressure sensor [203] is a device for measuring pressure gases or liquids. Pressure is the value of the application of the force required to stop a fluid from escalating and it is denoted as force per unit area. A pressure sensor behaves like a transducer and produces a signal as a function of the pressure applied. The DC Boost Step up Power High Voltage Generator Module [204] is an electronic circuit which gets low voltage input such 5 volt and converted it to high voltage say 230 V. The Global System for Mobile Communications (GSM) module [205] provides a standard collection of features and applications available to mobile phone subscribers. The 3GPP collaboration defines the standards to be implemented by the GSM module and the same is implemented by mobile service providers and device manufacturers. Once the Subscriber Identity Module (SIM) card is fixed in the powered phone, the mobile device scans for the nearest strong base transceiver station (BTS). The control channel is utilized by the mobile device to perform self-identification to the network. Once all the processes are completed, the mobile device is said to be connected to the network. The pulse sensor [206] can collect real time pulse rate or heart rate data and can transmit it to other modules. This sensor measures the changes in the volume of blood through an organ in the human body which causes a change in the light intensity of that organ. The principle of photo plethysmography where the heartbeat can be measured based on the optical power changes that may occur as light is absorbed or scattered during its path through the blood.
Fig. 3 shows the flow diagram for the data flow within the safety device. Once the device is activated [301], the pressure [302] and the heart rate sensor [303] are initialized. These sensors keep reading the user’s data of pressure [304] and the heart rate [305]. Once the pressure [306] or heart rate [307] is exceeded, immediately the security services [308] are activated. The GSM [309] module activates the notification action of sending emergency messages and calling stored emergency numbers [310]. The GPS [311] module activated the location tracking process and sends the location details [312] to the nearest police station and emergency contacts. The high frequency buzzer [313] immediately triggers a loud high pitched sound alarm [314] which will identify the location of the incident to the immediate public. Furthermore, the high voltage generator [315] generates a high voltage shock [316] which will prevent the attacker from causing any more harm. To deactivate the security services [317], there is a need to check if the problem is completely solved and the device can be deactivated [319] only by the authorized user’ voice and biometric input [318]. Thus the securityof women is ensured and further problems are avoided.
