The present invention relates to a field of biological posture monitoring. More
particularly, the present invention relates to system and method for detection and correction of an
abnormal posture of a human being.
Background
[0002] 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.
[0003] Generally, sitting jobs result in an insufficient physical mobility of users. Lack of
exercise results in billions of dollars in direct medical expenses. Office work hours, electronic gaming
and TV entertainment times, and the proliferation of modern life equipment (e.g., elevators, electric
traffic, home and online shopping, and so on) have all contributed to an increase in the way people sit
for lengthy periods of time. Long-sitting lifestyles contribute to bad posture, hypertension, neck
weariness, heart disease, colon cancer, joint discomfort, and venous anger, among the other things,
which increases the likelihood of developing aforementioned health problems.
[0004] Additionally, low back pain and other back disorders are also caused by lack of
exercises and bad posture. Individuals with back pain can be expensive, and back discomfort is the
leading and most prevalent cause of job losses in society. Maintaining an appropriate posture, especially
when sitting for long periods of time, can help many people avoid or lessen back pain. Many individuals
understand the importance of an appropriate posture, yet it can be difficult to maintain a posture that
opposes the gravity of the spine when sitting for lengthy periods of time.
3
[0005] Currently, certain portable devices can measure one or more vital signs, such as
wireless heart rate monitors and other wearable gadgets. Other portable gadgets can monitor an activity
level or measure the number of steps taken. A number of postures correcting belts are also available in
market intended to maintain an appropriate posture of neck and back of an individual. Though the
posture correcting belts can help maintaining an appropriate posture but medical professionals may not
recommend its long-term use as it may cause atrophy of a few muscles of the spine due to lack of use.
[0006] Another concern in the modern society is the safety of an individuals. In an event of
emergency such as an accident or stalking of a woman, it has become a necessity to adapt preventive
measures. Certain sensors are available to detect an event of accident and few portable gadgets are
available which can be utilized in an event of stalking of a woman. Though aforementioned sensors and
portable gadgets have resolved the issue up to a certain extent, they have certain limitations. The sensors
detect an event of accident on the basis of shock, but it cannot determine the state consciousness of one
or more individuals, and the portable gadgets cannot detect the presence of a stalker.
[0007] It is therefore, desired to design a system and method which can provide an alternative
to maintain an appropriate posture, measurement of body vitals, detection of consciousness of an
individual, as well as measures for women safety.

Detailed Description
[00032] The following discussion provides many example embodiments of the inventive
subject matter. Although each embodiment represents a single combination of inventive elements, the
inventive subject matter is considered to include all possible combinations of the disclosed elements.
Thus, if one embodiment comprises elements A, B, and C, and a second embodiment comprises
elements B and D, then the inventive subject matter is also considered to include other remaining
combinations of A, B, C, or D, even if not explicitly disclosed.
[00033] The present invention relates to a field of biological posture monitoring. More
particularly, the present invention relates to system and method for detection and correction of an
abnormal posture of a human being.
[00034] Fig. 1 illustrates an exemplary architecture of a system 100 to detect and an abnormal
posture of a person, in accordance with embodiment of present disclosure.
[00035] In an embodiment, the system 100 can comprise a wearable device 102, a control
unit 104, a computing terminal 106, data communication means to establish communication with
different components, and an electrical energy source to provide electrical energy to the one or more
components of system 100. The aforementioned elements of system 100 are communicably coupled
with each other.
9
[00036] In an embodiment, the wearable device can comprise a first wearable unit 102-A and
a second wearable unit 102-B, wherein the first wearable unit 102-A can be arranged to be worn around
a neck region of the person and the second wearable unit 102-B can be arranged to be worn around a
thoracic region of the person.
[00037] In an embodiment, the first wearable unit 102-A can comprise a cervical sensor 102-
AA, a gas sensor 102-AB and a button 102-AC.
[00038] In an embodiment, the cervical sensor 102-AA can be arranged to determine the
direction of movement of a neck of the person. The cervical sensor 102-AA may comprise a central ball
of dielectric medium which can be placed between a cube of conducting plates. When the person moves
the neck in any direction, the capacitance in that direction can change. The change of capacitance can
be amplified using a transistor to generate a signal, which can be utilized in detection of the abnormal
posture of neck of the person. The cervical sensor 102-AA can be efficiently utilized for the treatment
of cervical spondylosis by monitoring the abnormal posture of the neck. The cervical sensor 102-AA
can help the person to maintain the neck in proper position, thereby reducing chances of the person
being affected by cervical spondylosis.
[00039] In an embodiment, the gas sensor 102-AB can be arranged to determine a
concentration level of alcohol in a surrounding ambiance, which can be an effective measure for women
safety and can help in reducing the crime rates. The gas sensor 102-AB may have a sensitive filament
made of SnO2. In the presence of clean air, the sensitive filament may have lower electrical conductivity.
When vapour of alcohol or smoke of cigarette is introduced, the filament’s conductivity may rise, and
the amount of change in its conductance/resistance can be used to indicate the equivalent gas
concentration. The gas sensor 102-AB can be selected from MQ-3 sensor, MQ-5 sensor, MQ-135
sensor, etc.
[00040] In some embodiment, the button 102-AC can be arranged to be utilized in an event of
emergency. The button 102-AC can initiate a communication which may include a call, a message or a
10
current location of the person. The button 102-AC can contribute to women safety by initiating a
communication (call, message or current location) in case of being stalked.
[00041] In an embodiment, the second wearable unit 102-B can comprise a heart rate sensor
102-BA, a force sensitive resistor sensor 102-BB, a position determination sensor 102-BC and an alert
means 102-BD.
[00042] In an embodiment, the heart rate sensor 102-BA can be arranged to determine a heart
rate of the person, thereby contributing to a proper health monitoring as heart rate can be a vital health
parameter. The heart rate sensor 102-BA may consist of a light-emitting diode (LED) and a detector
like a light detecting resistor or a photodiode. The heartbeat pulses may cause a variation in the flow of
blood to different regions of the body. When tissue is illuminated with the light source, i.e. light emitted
by the LED, it either reflects or transmits the light. Some of the light can be absorbed by the blood and
the transmitted or the reflected light can be received by the light detector. The amount of light absorbed
may depend on the blood volume in that tissue. The detector output can be in the form of the electrical
signal and can be proportional to the heart rate of the person.
[00043] In an embodiment, the force sensitive resistor sensor 102-BB can be arranged to
determine a posture of a back of the person. The force sensitive resistor sensor 102-BB may comprise
a material that can change its resistance when a force or pressure is applied. The material can usually
be composed by two substrate layers, followed by a conductive film and a plastic spacer, which may
include an opening aligned with an active area. After the plastic spacer, there can be a conductive print
on substrate. When a force is applied on the force sensitive resistor sensor 102-BB because of the
abnormal posture of the back of the person, the conductive film may deform against the substrate. Air
from the plastic spacer opening can be pushed through an air vent, and the conductive film may come
into contact with the conductive print on the substrate. The more of the conductive print get in touch
with the conductive film, the lower may be the resistance, thereby generating a high value current.
[00044] In an embodiment, the position determination sensor 102-BC can be arranged to
determine a current location of the person. During extremities such as accident, collapse due to ill health,
11
stalking of a woman, etc., the determined current location of the person may play a vital role in women
security and health recovery (by immediate treatment at hospitals), as the medical personal, police,
guardians etc., can reach the determined current location as soon as possible. The position determination
sensor 102-BC can comprise a receiver with an antenna that can use a satellite-based navigation system
with a network of satellites in the orbit around the earth to provide position, velocity, and timing
information.
[00045] In some embodiment, a humidity sensor (not shown in FIG 1) can be arranged on the
second wearable unit 102-B to determine a humidity and a temperature of the surrounding ambience.
The humidity sensor may contain a thermistor and a ceramic substrate sandwiched between two
electrodes. When the temperature or the humidity varies, resistance across the circuit may also fluctuate.
This fluctuation can be stabilized by a capacitor of suitable value and an electrical signal can be
generated, which can be amplified by a transistor.
[00046] In some embodiment, a dust sensor (not shown in FIG 1) can be arranged on the
second wearable unit 102-B to determine the presence of dust particles in the surrounding ambience.
The dust sensor may utilize laser scattering to radiate suspending particles in the air, followed by
collection of scattered light to obtain the curve of scattering light change with time, thereby generating
an analog signal.
[00047] In some embodiment, an infrared sensor (not shown in FIG 1) and an ultrasonic sensor
(not shown in FIG 1) can be arranged on the second wearable device 102-B to determine the presence
of a stalker, thereby helping in women safety. The infrared sensor (IR) used for human motion detection
can be a passive infrared sensor (PIR). The conventional PIR sensor may work by sensing the IR signals
from a human body through a couple of parallel slots on their front lens, and its internal circuitry may
activate only when the IR signals cross between these sensing slots ("visions"). The crossing of IR
signals across the sensing slots may enable the PIR circuit to translate the information into two
corresponding alternating pulses, which can be in turn rectified to generate the triggering signal. On the
other hand, the ultrasonic sensors may generate high frequency sound waves and evaluate the echo
12
which is received back by the sensor. The time interval between sending the signal and receiving the
echo (time-of-flight, TOF) can be calculated in order to determine the distance of the stalker.
[00048] In an embodiment, the alert means 102-BD can be arranged to create an alert on the
basis of signal received from a microprocessor 104-B. The alert means 102-BD can be selected from
an eccentric rotating mass motor (which can create vibration), a buzzer (which can create sound), a
display device (like LED, LCD etc.) or electroshock electrodes.
[00049] In an embodiment, the control unit 104 can comprise a non-transitory storage device
104-A and the microprocessor 104-B.
[00050] In an embodiment, the non-transitory storage device 104-A can be configured to store
one or more executable subroutines that can be utilized by the microprocessor 104-B. The nontransitory storage device 104-A can be a flash drive, RAM or other known types of electronic data
storage devices.
[00051] In an embodiment, the microprocessor 104-B can be configured which is coupled to
the non-transitory storage device 104-A. The microprocessor 104-B can receive information from the
cervical sensor 102-AA, the gas sensor 102-AB, the heart rate sensor 102-BA, the force sensitive
resistor sensor 102-BB, and the position determination sensor 102-BC. The microprocessor 104-B may
execute one or more subroutines which may include machine learning model (e.g., CNN, HMM,
artificial intelligence, deep learning etc.) to analyse the received information from the cervical sensor
102-AA, the gas sensor 102-AB, the heart rate sensor 102-BA, the force sensitive resistor sensor 102-
BB, and the position determination sensor 102-BC. The microprocessor 104-B can then transmit a
signal to activate the alert means 102-BD on the basis of analysis. The microprocessor 104-B can
transmit a notification to the computing terminal 106, wherein the notification may comprise data
related to the abnormal posture of the neck of the person, the concentration level of alcohol in the
surrounding ambience, the heart rate of the person, the abnormal posture of the back of the person, and
the current location of the person. The microprocessor 104-B can be a microprocessor, a set of
microprocessors, or complex instruction set computing (CISC) microprocessor, or reduced instruction
13
set (RISC) microprocessor, or very long instruction word (VLIW) microprocessor, or any other type of
processing circuits.
[00052] In an embodiment, the computing terminal 106 can be utilized to receive notification
from the microprocessor 104-B. The received notification can determine abnormal posture of neck of
the person, the determined concentration level of alcohol in the surrounding ambience, the determined
heart rate of the person, the determined abnormal posture of back of the person, and the determined
current location of person. The computing terminal 106 can be selected from a laptop, a desktop, a
mobile, etc.
[00053] In an embodiment, the first wearable unit 102-A and the second wearable unit 102-B
may comprise the heart rate sensor 102-BA, a pedometer sensor (not shown) and other known sensors
to determine body vitals such as heart rate, blood pressure, level of SPO2 in the blood, total step count,
and total number of calories burnt, etc. Aforementioned body vitals can be closely monitored to
maintain a fitness level and to determine the health condition of the person.
[00054] In an embodiment, the second wearable unit 102-B can comprise plurality of motors,
that can be utilized to adjust the plurality of straps of the second wearable device 102-B depending upon
the signal received from the microprocessor 104-B. The microprocessor 104-B can send signals to rotate
the plurality of motors in a clock-wise direction or an anti-clockwise direction to tighten or loosen the
plurality of straps in order to reverse the abnormal posture.
[00055] In an embodiment, the alert means 102-BD can be an eccentric Rotating Mass
vibration motor (ERM), that may be a DC motor with an offset (non-symmetric) mass attached to a
shaft. As the ERM rotates, the centripetal force of the offset mass may be asymmetric, which may result
in a net centrifugal force, that may cause a displacement of the motor. With a high number of revolutions
per minute, the motor can be constantly displaced and moved by the asymmetric forces. It can be this
repeated displacement that may be perceived as a vibration. The alert means 102-BD can be a speaker
which can produce sound upon receiving the activation signal from the microprocessor 104-B. The alert
means 102-BD can be a display screen, which can be a light emitting diode (LED), liquid crystal display
14
(LCD), etc. The alert means 102-BD can be electroshock electrodes which can generate a minor electric
current to provide an electric shock to the person.
[00056] In an embodiment, the control unit 104 can determine the consciousness level of the
person based on the information received from the cervical sensor 102-AA and the force sensitive
resistor sensor 102-BB. The microprocessor 104-B may perform analysis on the received information
and can detect the abnormal posture of the person. Thereafter, the microprocessor may activate alert
means to provide indication regarding the abnormal posture. Even though, if the abnormal posture
persists for a pre-set time, the person can be considered as unconscious.
[00057] In an embodiment, an Emergency Response Support protocol (ERSP) can be utilized
to establish a communication to some pre-stored contact number (stored in the non-transitory storage
device 104-A) in an event when the person is recognized to be unconscious. These pre-stored contact
numbers can be of police, hospitals, guardians and relatives of the person, etc.
[00058] In an embodiment, the button 102-AC can be utilized to deactivate the ERSP in an
event when the person faces temporary unconsciousness. The person can be temporarily unconscious
because of certain diseases such as epilepsy, alzheimer, hypotension, hypoglycaemia, etc. The person
can be temporarily unconscious during a minor accident.

15
perform sampling of the electrical signal (continuous time signal) in order to reduce it into discreet time
signal. The ADC may take the magnitude of the voltage and convert it to a binary value which may
represent the magnitude that can generate a signal, which can be provided to the data receive unit 204.
[00061] In an embodiment, the data receive unit 204 can be configured to receive the signal
originated from the sensing unit 202, in runtime or near runtime manner, through known communication
network (e.g., wired or wireless network).
[00062] In an embodiment, the analysis unit 206 can be arranged to perform removal of noise
(any unwanted signal that’s combined with the desired signal present, if any) using known filters such
as low pass filters (e.g., moving average), high pass filters, band pass filters and band reject filters. The
analysis unit 206 can perform necessary analysis to determine the abnormal posture of the neck of the

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 refer 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.
