Description

PERSONAL SAFETY SYSTEM AND A METHOD THEREOF

TECHNICAL FIELD OF THE INVENTION The present invention relates generally to safety systems. More particularly, the invention relates to a personal safety response system and a method for detecting heart rate of an individual and finding a plurality of physiological parameters. It may be used for sensing different physiological parameters and providing an alert for predefined parameters. The application area may include but is not limited to detecting and alerting for changes in physiological conditions when confronted with a frightful situation, increase/decrease in blood sugar level etc.

BACKGROUND AND THE PRIOR ART In the present age, women are the prime targets of social violence. Crimes like molestation, rapes, kidnapping, domestic violence etc. are on a rise. Confronting such crimes has not been easy for women. There have been attempts in the past to provide self-defense devices to potential victims in the form of pepper sprays, personal alarms etc. However all of them suffer from the drawback that the victim has to initiate their use. They do not automatically trigger on their own. For e.g. during an attack, the victim may require to access the pepper spray from a bag or some other carrier and at that particular moment either she may forget or she may have already been dispossessed of her belongings. Thus there is a need for a system that works automatically when an individual is confronted by an attacker.

According to the study of Fight or Flight by the Harvard Physiologist, Mr. Walter Cannon (http://en.wikipedia.org/wiki/Fight-or-flight_response) there are major changes which happen in our body as soon as we sense fear, and danger. In the case of women the study has shown that they have another kind of reaction added to the fight or flight (either fight the danger or run away from it), they tend to freeze. The study (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2489204/) says that: "Despite evidence suggesting that tonic immobility may be a key facet of alarm reactions, freezing has received relatively little scientific attention in humans. One exception is the PTSD/rape literature wherein several studies have described a rape- induced paralysis that appears to share many of the features of tonic immobility. This literature suggests that a relatively high percentage of rape victims feel paralyzed and unable to act despite no loss of consciousness during the assault. Since fear, predation, contact, and restraint are common to both rape and the induction of tonic immobility in animals, it has been concluded that these phenomena are essentially isomorphic."

So with women the term Fight, Flight or Freeze can be referred to as the response in a situation of facing danger or sensing fear. In such a situation the "weapons" already in possession of the victim are not of much use to her.

The science of fear is the reason of innovation of such a device which works on its own, operates automatically and provides help as soon as possible when confronted with a situation. As one confronts an attacker, the emotional part of the Brain called Amydgala which is always looking for threats to our body starts working in overdrive. It sends the signal thru our autonomous nervous system to the adrenal glands to prepare our body for an attack. This is all done automatically by our brain to create reflex action. The Adrenal Glands rush Cortisol and Adrenaline in the Blood and the blood is rushed to the muscles to prepare for a Fight or Flight syndrome. All other internal process of Digestion in stomach and all are stopped and the focus gets shifted to the muscle, thus wanting more Oxygen in the blood.

Our intake of Oxygen increases while we start breathing faster. This is all done without any of our conscious efforts. Thus our heart rate increases and pumps more blood to the muscles. While all this is happening, the other part of the brain called the Hippocamus which acts as an emotional part of the brain, starts giving logical thoughts such as, a) is my attacker stronger than me? b) will I be able to fight him back? c) whom should I Call for help? d) should I scream? Such logical questions crowd one's mind when facing an attack and thus makes decision making ability slow and at that time of no use, as by then the individual is overpowered by the attacker.

published on 8 October 201 1 , clearly provides that the heart rate shoots up dramatically in response to adrenaline, preparing us for a 'fight or flight' reaction. Further, it provides that the normal heart rate undergoes healthy variation, going up in response to some conditions, including exercise, body temperature, body position (such as for a short while after standing up quickly), and emotion (such as anxiety, fear and arousal).

Thus a need was felt to develop a system which could record the rush of the adrenaline, and its reactions and send out distress signals and the location of the victim at that very moment, automatically, without any manual stimulation.

There have been monitors and sensors in various forms that have been developed in the past to monitor physiological parameters.

US 831 1770 describe an activity monitoring system that includes a device that monitors and displays the physical activity of the user that includes a motion sensor and an altitude sensor.

US2012/0172684 describes a heart rate monitor that is in the form of a wristwatch and continuously monitors the heart rate and sends signals to another device that runs an application that decodes the processing data, processes the signal and transmits it back to the wristwatch device US 8033959 describes a portable fitness monitoring system that combines a monitoring device with a sensor and provides performance data logging and entertainment to the user. US 8398546 describes a nutrition and activity management system that includes a device such as an armband that transmits the physiological parameters of the wearer to a remote location for later manipulation and presentation to the recipient over an electronic network such as the Internet. KR20100077942 describes a lifesaving system in the form of a wrist watch that often checks the heart rate of the wearer and sends a distress signal to a pre-determined location on the heart beat being suddenly stopped.

US6338719 describes a system for detecting various vascular conditions using an occlusive arm cuff plethysmograph. The processing means diagnoses and predicts various vascular conditions pertaining to the patient by comparing or correlating the analyzed arterial and endothelial function data with the computer models stored within the database and presents the findings on a display. All these inventions suffer from the drawback that they do not register a sudden change in the physiological condition of the user that feeds and triggers a mobile application that sends messages and/or alarms to preset destinations. Detection of different physiological conditions using fitness bands is also debatable as provided in the following news article by Nick Bilton:

(http://epaperbeta.timesofindia.com/Artide.aspx7eid~31808&articlexml^"Suspect- results-plague-fitness-bands-29042014017037)

Accordingly, one aspect the present invention is directed to a personal safety response system (100) and a method for detecting heart rate of an individual and finding a plurality of physiological parameters based on the heart rate data readings. The safety response system (100) includes a sensory means (101 ) which continuously detects a plurality of heart rate data.

In one embodiment there is provided a sensory means (101 ) housed within a housing means (101 A, 101 H). The sensory means (101 ) is ensconced in the inner wear of an individual. The housing means (101 A, 101 H) which includes a physical size & shape including the material of the housing means (101 A, 101 H) is such that it facilitates a proper coupling to the user. The housing means (101 A. 101 H) may preferably be made of soft silica and the like which can be comfortably carried in all the weather conditions. It may preferably be water resistant so as to protect the inner electronic components. Housing means top (101A) and housing means bottom (101 H) are joint at housing joint (600) to define the housing means (101 A, 101 H). In an exemplary embodiment the sensory means (101 ) is placed on the bridge of the bra and the triangular form of the sensory means (101 ) makes it fit well in between the bust area. The placement is ideal as the wearer does not feel discomfort wearing it for long intervals. The bottom strap of the bra keeps the sensor tightly fastened to the skin minimizing the data loss. The strap also doesn't let the sensor move from its place which again could result in the data loss. The holding means (101 1) for clamping may be a transparent plastic so as to take the color of the innerwear and keep the setup in its exact place. The holding means (101 1) is attached to the sensor with a spring action to keep it hanging with the innerwear. The sensory means interface (101 D) remains in contact with the skin of the body. The sensory means (101 ) is substantially a photoplethysmogram (PPG) sensor integrated to a microcontroller (101 F) for determining the heart rate data. The sensory means (101 ) is integrated to a data acquisition unit which forms part of the microcontroller (101 F) to record the heart rate data. The change in volume caused by the pressure pulse is detected by illuminating the skin with the light from the LED and then measuring the amount of light either transmitted or reflected to a photodiode.

In one of the exemplary embodiment the sensory means (101 ) is a noninvasive transducer that measures relative changes in blood volume or the oxygen saturation under the skin in the chest area. The blood volume pulse (BVP) sensor reads the relative changes in blood volume. With each heartbeat, the change in arterial blood volume momentarily increases or decreases the amount of Hb and Hb02. This results in the absorption of more light during the systolic phase and less light during the diastolic (resting) phase of the heart during any given beat. The photodiode output level is affected by variation in the level of light absorption. Hence, we obtain a waveform output level and determine the peaks between heartbeats. We can estimate the heart rate (number of beats per minute) from the measured peaks. The LED Emitter and the Photo detector are placed side by side to reduce the space and size of the measuring site, making it place over the skin and not in-between 2 LEDS. The device acquires the PPG data, processes it and then sends it to a processing means/telementary manager, say a phone (Smart Phone) which has a decoding application installed in it.

There is provided a transmission means integrated to the data acquisition unit for transmitting the heart rate data detected by the sensory means (101 ). The transmission means is substantially a Bluetooth™ or the likes. The transmission means is further coupled to a processing means which in turn is integrated within the computing means (102). The transmission means (102A) makes use of a Bluetooth™ transmitter (101 E) on the sensory means (101 ) and a Bluetooth™ receiver on the computing means (102). Data transmission is established after pairing between the transmitter and receiver. In an exemplary embodiment the transmission means may comprise a wireless mode like Bluetooth™ (BLE) at a very non harmful frequency of 2.4 Ghz of Radio frequency thus giving a real time heart rate of the user. The computing means (102) is substantially a smart phone or the like computing device. The processing means is integrated within the computing means (102) and is having a software program, a mobile application or the like installed therein to process the heart rate readings. The software/application program can be activated only after the user validation by entering the username and password. If the validation is correct, only then the whole sequence of the application is processed. The web call object sends the encrypted data to the data server (103) for authentication, the response is received in the callback, and in case of affirmative response, user details are stored in the application memory and the user is taken to the main screen. Appropriate error messages are given in case otherwise. The sign up process is almost similar to the login process instead the values concerned here are full name, username, password and email.

The processing means is preprogrammed for sampling the plurality of heart rate data readings. In one of the exemplary embodiment, the processing means is configured to sample last five readings. The processing means further compares the next sampled heart rate readings to the preceding heart rate reading and detects a jump in the heart rate compared to preceding heart rate readings if any. The processing means is calibrated to detect a jump of around 20 percent preferably for detection of fearful situation. The processing means includes a database of heart rates pertaining to different physiological conditions including but not limited to fearful situation wherein heart rate range of around 1 10 to 150 has been defined. More precisely, a range of heart rate between 115 to 140 along with a jump of 20 percent in heart rate would be calibrated preferably to detect the fearful situation. The database comprises a plurality of heart rate ranges qualifying for different physiological conditions. After finding a matching physiological parameter, an output instruction is generated automatically to be transmitted to a plurality of receiving stations thus providing a self-triggering system. In another embodiment of the invention there is provided a processing means that enable the computing means (102) to auto answer incoming signal thereby providing firsthand information of the individual.

In another embodiment of the invention, the processing means generates the output instruction based on a predefined calibration and transmits the same to a plurality of receiving stations and a continuous tracking data to a data server (103). The receiving station among others may include the smart phone and the likes of relatives, friends, police etc. the receiving station may comprise: receiving station friend (104), receiving station relative (105), receiving station police (106). The communication between the computing means (102) and the receiving stations including the data server (103) is facilitated through a data network like Wi-Fi, or mobile network like GSM, CDMA or the like.

In addition to the aforesaid receiving stations, the data server is programmed for triggering a nearest user of said safety response system. The data server collects the tracking details of the user continuously and triggers the nearest user who can assist at the time of distress. The personal safety response system users can therefore develop a community and help each other at the time of distress.

The data server (103) is integrated to a web portal for an instant location tracking of the individual on display means (107). Additionally, the processing means is programmed for providing a route map and contact of the nearest police station on a display means (107).

Another aspect of the invention provides a processing means enabling the computing means (102) to provide a continuous voice recording live feeds from the individual's vicinity to the data server (103).

The above method steps are facilitated through a combination of hardware and software installed in the processing means. A function with the name 'startSession' is responsible for notifying the data server (103) of a threat and creating a separate session for it so that the location tracking and sensor data can be logged with respect to the current session.

In one exemplary embodiment after receiving response from the data server (103) confirming a fearful situation, a police siren starts playing and the web call for sending mails/messages is made. 'sendMail' function is made to reoccur approximately after 3 minutes with the help of a timer function.

In another exemplary embodiment, after the police siren stops, an audio recording in short bursts of approximately 5 seconds are facilitated, recorded and stored in the phone's application memory. This code starts the audio recording and restarts the process after saving a 5 second record.

For location tracking, the system among others may make use of Google™ places API. It also facilitates route map of the nearest police station to the victim and shows driving directions for it. The web service gets the result and uses Google™ Maps API to show driving directions on the phone. This particular function gets the nearest station coordinates and then uses driving directions API to get the route. The route is then animated onto a map control. Stop session is the terminator function, which will end the session on the data server (103), update the values in the application so they stop sending sensor values and location data to the data server (103). This function brings the application to a rest state.

Another aspect of the invention provides a powering means (101 G) and a switching means attached thereto for powering the sensory means (101 ). The powering means (101 G) comprises a charging slot for recharging the powering means (101 G). It can be a micro USB charging point and the like. The powering means (101 G) may comprise 300MH lithium Ion Battery. One exemplary embodiment provides a battery life indicator (101 B) Another aspect of the invention provides Soft TPU rubber material may be used to cover the micro USB port for preventing the moisture or sweat from entering into the Circuit. The outer layer of the hard shell may be covered with soft silica also known as silicone to give a skin like feel to the device and to make it comfortable and easy to wear for a long time.

The system in accordance to the present invention detects a plurality of physiological conditions like rise/drop in blood sugar and the likes based on the heart rate data.

Another embodiment of the present invention provides a device forming part of the personal safety response system (100) for detecting a heart rate. The device among others comprises a sensory means (101 ) substantially a photoplethysmogram (PPG) integrated to a microcontroller (101 F) housed in a housing means (101 A, 101 H) ensconced in the inner wear of an individual for detecting heart rate data. There is provided a data acquisition unit integrated to the sensory means (101 ) to record the heart rate data. The transmission means is substantially a Bluetooth™ or the likes integrated to the data acquisition unit for transmitting the heart rate data detected by the sensory means (101 ). The sensory means (101 ) and transmission means are integrated to a switching means for providing an ON or OFF control during operation of the sensory means (101 ) and the transmission means. There is provided a resetting means (101 C) to reactivate the sensory means (101 ) and a powering means (101 G) attached thereto for powering the sensory means (101 ). The powering means (101 G) comprises a charging slot for recharging the powering means (101 G) (101 G). A holding means (101 1) is attached to the housing means (101 A, 101 H) for clamping on the innerwear of the individual.

The invention will now be illustrated with a working example which is intended to illustrate the working of the invention and not intended to take restrictively to imply any limitation on the scope of the present invention.

Example The system was tested on people of ages ranging between 20 to 36 years. Each person was made to wear the device. The mobile application was uploaded on the wearer's phone. A frightful situation was created, without the knowledge of the wearer, in which the wearer reacted spontaneously. On facing a frightful situation, the wearer's heart rate showed a sudden jump that triggered the mobile application to send the data to the data center.
