BACKGROUND
[002]The background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] Snake bite is an injury caused by a bite of a snake, especially a venomous
snake. It is a neglected public health problem in tropical and subtropical countries, where rural populations are mainly affected. Snakes are very common in rural areas with farms and agriculture as they actively prey on pests such as mice and rats. Majority of the snake bites happen in rural areas because the bed is likely to be low to the ground (or on the ground) and likely the only heat source in the building. This would entice any snake in the building and looking for heat to head directly to the bed. The same experience is common for farmers when they are walking in farms at night
[004] It is a common occupational hazard mainly in farmers, plantation workers,
herders and labourers leading to significant morbidity and mortality that remains largely unreported. These groups often lack even the most basic protections such as snake-proof footwear or bed nets.
[005] The most affected region in the world is South East Asia because of dense
population and extensive agricultural practices. Snake bites are now a "global health priority" according to a new resolution passed by the World Health Organization (WHO) and WHO has included snake bite in its list of neglected tropical conditions in 2009. The true global burden of snake bite is not known due to lack of standardized reporting and underreporting. It is documented that there are 54,00,000 snake bites with 2,50,000 'envenomation' and around 1,25,000 fatalities annually in the world.
[006] According to the World Health Organization (WHO) around five million
snake bites occur each year, although venom is only injected in just over half of cases. From

blindness to amputations, hundreds of thousands of people are left with permanent disability
after being attacked by snakes. The WHO describes such cases as among the most neglected
tropical diseases. With some 50,000 citizens dying annually from snakebites, India is
compelled to explore a range of effective methods to deal with the problem, which the WHO
characterises as a neglected tropical disease. India accounts for about half of all global
snakebite deaths.
[007] Efforts have been made in the past to overcome problem associated with snake
detection and warning. Snake repellent are commercially available, but they not apt due to its
bulkiness. Being bulky, it is not practical to be used while walking during night times through
agricultural farms in rural areas. Also, it is not accurate and efficient as it fails to work on
plywood and filter paper during night-time and shows 50% results on cloth.
[008] The existing technique of using a temperature sensor can detect the heat
radiations from the snake, however they are not a viable option owing to the fact that they are
highly priced. Further, at high-temperature, the thermal sensors are susceptible to in-
homogeneity. Moreover, image processing technology cannot be used for the purpose as it is
expensive, and its accuracy is affected by the obstructions in the path of the sensors.
[009] If sound frequency sensor is used to detect snakes in the device, it becomes
extremely bulky, because the mic operates at 80 Hz to 15 KHz with non-linear response
throughout the bandwidth. Anything lesser than 80 Hz is difficult to detect and the size of
detector is inversely proportional to frequency, making it bulky and impractical.
[0010] There is therefore a need in the art to provide a portable snake detecting device
that overcome the above-mentioned and other limitations of the existing solutions and utilize
techniques, which are portable, robust, accurate, efficient, cost effective and simple.

[0042] In an embodiment, the device comprises an illumination unit to illuminate the
area in close proximity of the device.
[0043] In an embodiment, the control unit comprises of one or more processors
coupled to a storage memory configured such that to classify the sensed signals by matching
the extracted parameters with a pre-loaded dataset comprising a set of intensities and
frequencies of one or more sound signals associated with snakes and generate an alert signal
based on positive matching of the extracted parameters and the pre-loaded dataset.
[0044] FIGs. 1A and 1B illustrates exemplary device with attached and detached
torch and FIG. 2 illustrates a flow diagram illustrating the working of snake detection and warning device in accordance with an embodiment of the present disclosure.
[0045] In an embodiment, an apparatus for snake detection and warning device 100
can include a casing. The casing can be used for housing various components of the device 100. The device 100 can include a set of sensors 104 for sensing one or more signals from in proximity of the device 100. The set of sensors 104 can includea microphone for sensing various signals from area close to the device. The area can include but not limited to 5 metres in either direction from the set of sensors 104.
[0046] In an embodiment, the set of sensors 104 enable sensing of frequencies less
than about 80 hertz as the snake generates a very low frequency in the range of 10 Hz to 70 Hz. Snakes make specific low frequency sounds both in hibernation and active mode. The sibilance of snakes produces specific low frequency and the intensity depends on the species of the snake.
[0047] Further, the microphone can be configured such that it can capture frequencies
lower than 80 Hz. The microphone can be coupled with a resonating device to enable sensing of the one or more signals in a frequency range of 10 Hz to 1 KHz. As the microphone is resonator device, the frequency that microphone can capture depends on resonant frequency. Resonance is defined as the increase in the amplitude of the oscillation of an electric system or a mechanical system exposed to a periodic force whose frequency is similar to that of natural undamped frequency of the system. A device that exhibits resonance is called a resonator. A resonator naturally oscillates with greater amplitude at some frequencies, called resonant frequencies. Attenuation and noise are minimum at the resonant frequency. Resonators can either be used to generate waves of specific frequencies to select a particular range of frequencies from the signal. Therefore, microphone can detect one or more signals in a frequency range of 10 Hz to 1 KHz. Since the size of a detector for signals is inversely
8

proportional to the frequency of the signals. The microphone can include vibrating plates
configured such that to reduce the bulkiness.
[0048] In an embodiment, the device 100 can include an illumination unit 102 for
providing illumination in case of dark or low illumination scenario. The illumination unit 102
can include a bulb, an LED, a CFL and the like to provide illumination.
[0049] In an embodiment, the device 100 can include a control unit 108. In an
embodiment, the control unit 108 can include one or more processors or controllers.
Examples of controllers include, but are not limited to PIC® 16F877A microcontroller, AVR
® ATmega8 & ATmega16, Renesas® microcontroller and the like. Examples of processor
can include, but are not limited to, an Intel® Itanium® or Itanium 2 processor(s), or AMD®
Opteron® or Athlon MP® processor(s), Motorola® lines of processors, FortiSOC™ system
on a chip processors or other future processors.
[0050] In an embodiment, the control unit 108 configured to extract one or more
parameters from the from the sensed signals. The one or more parameters includes but not
limited to frequency, amplitude, intensity of each of the sensed one or more signals. Further,
the control unit 108 configured to classify the sensed one or more signals by comparing or
matching the extracted one or more parameters of the sensed one or more signals with a
preloaded dataset. The dataset can comprise a set of intensities, intensities and the like.
[0051] In an embodiment, now based on classification of the one or more sound
signals a sound (generally in form of hiss) produced by snake can be recognized. Now, based
on recognition an alert signal can be generated such that the alert signal signifies existence of
snake in an area in close proximity of the device 100.
[0052] In an embodiment, the device 100 can include an alert unit 106. The alert unit
106 can be used for providing any or a combination of a visual alert, an audio alert and
vibration alert based on the generated alert signal. The alert unit 106 can include but not
limited to a vibrating element for providing vibration alert, or a light source to provide visual
alert and a sound source to provide the audio alert.
[0053] In an embodiment, the various components of the device 100 can be built or
moulded such that any of the components can be detachable from the device without straying
away from a basic function of detection of the snake and further based on detection generate
an alert.

[0055] In context to flow diagram 200. Block 202 can pertain to receiving one or
more sound signals from a set of sensors that can pertain to audio signal from insects, or
animals, surrounding sounds or sound produced by snake. further, block 204 pertains to
classification of the received sound using classifier. Parameters can be extracted from the
received signals and then the extracted parameters can be matched with prestored signals.
The prestored signals can be stored on a database as illustrated by clock 206. Further, block
208 pertains to detection of the snake and generating an alert based on detection of the snake.
[0056] In an embodiment, the device 100 would enable detection of the snake in close
proximity of the device 100 irrespective of climate (hot, rainy or cold). Thereby, can be used in tropical areas, remote areas for detection of the snake in surrounding area thereby avoiding any conflict of a human and the snake and thus can be helpful in reducing death or fatal injuries due to snake attack.
[0057] Thus, it will be appreciated by those of ordinary skill in the art that the
diagrams, schematics, illustrations, and the like represent conceptual views or processes illustrating systems and methods embodying this invention. The functions of the various elements shown in the figures may be provided through the use of dedicated hardware as well as hardware capable of executing associated software. Similarly, any switches shown in the figures are conceptual only. Their function may be carried out through the operation of program logic, through dedicated logic, through the interaction of program control and dedicated logic, or even manually, the particular technique being selectable by the entity implementing this invention.

[0060] As used herein, and unless the context dictates otherwise, the term "coupled
to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0061] It should be apparent to those skilled in the art that many more modifications
besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C …. and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0062] While the foregoing describes various embodiments of the invention, other and
further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
