BACKGROUND
[0002] 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] Knowing exact timing of menstrual flow for females is bit difficult. So they have to
keep a check on it. As soon as their menstruation starts, their bottom wear gets spotted by that
menstrual blood. Therefore, females have to check their pre - menstrual flow by unusual or
unhygienic methods. As, there happens a variation in menstrual cycle so all time it is not possible
for girls to keep sanitary stuffs like pads, tampons, menstrual cups, and the likes. At ending
phase of their menstrual cycle, they again stay confused whether their cycle has fully completed
or not. For this, they have to keep wearing that sanitary stuff for a longer time till they get a full
surety regarding the completion of their monthly cycle.
[0004] Menstrual blood is contaminated and wearing sanitary stuffs like damp pad for long
is unhygienic and can lead to diseases such as skin rashes, urinary tract infection and vaginal
infection. A dried out pad, worn over a long time can also cause localized allergic reactions
leading to irritation, itching and uneasiness. Just to cover risk of spontaneous spotting at the
beginning of menstruation cycle females wear pads from the early morning of that estimated day,
which in turn leads to wastage of the sanitary stuffs. Therefore, if the females are notified and
become aware as their menstrual cycle starts and stop, the discussed problems can be avoided to
an extent.
[0005] There is a need to overcome the above mentioned problems by bringing solution, that
helps the females in alerting them for their start and end time of menstruation. It also helps them
to prevent from various infections and diseases which are cause by long usage of the damp pads
3
and dried pads. The present solution can enable females to stay hygienic, healthy and disease
free.

[0056] In an illustrative embodiment, the second set of sensors can include any or a
combination of fluid sensors, viscosity sensor, and the likes. The second set of sensors can be
configured to detect the fluidic parameters like viscosity of the fluid, and can correspondingly
generate a second set of electrical signals. The second set of sensors can be configured to detect
fluidic parameters apart from sweat, urine, water discharged by the subject. In another illustrative
embodiment, the first set of electrical signals and the second set of electrical signals can be
transmitted to the monitoring unit 106.
[0057] In an embodiment, the first portion 102 can include the litmus content configured to
configured to detect pH of fluid during the menstrual cycle of a subject, and correspondingly
changes colour. In an illustrative embodiment, the litmus content can include a predetermined
range between zero to fourteen on pH scale. The litmus content can be configured to change the
colour 104 based on the pH value of the fluid during menstrual cycle. The change in colour 104
of the litmus content depends on nature of fluid falling on the litmus content. The nature of fluid
can vary and accordingly the range between zero to fourteen of the pH value also changes. In
another illustrative embodiment, the fluid basic in nature gives different colour for the pH value
10
than the fluid acidic in nature. Also, the fluid with more basic nature and less basic nature gives
different colour for different pH value.
[0058] In an illustrative embodiment, the predetermined ranges between zero to fourteen on
pH scale can be further categorized on basis of acidic, basic and neutral nature of the fluid. The
predetermined range between zero to seven indicates acidic nature of the fluid in increasing
order. For example, when the fluid with acidic nature and pH value of three falls on the litmus
content or litmus paper, or the litmus strip, the litmus paper or the litmus strip changes colour
104 due to the acidic nature of the fluid. Similarly, when the fluid with acidic nature and pH
value of five falls on the litmus content or litmus paper, or the litmus strip, the litmus paper or
the litmus strip changes colour 104 due to the acidic nature of the fluid. The fluid with pH value
three is more acidic than the fluid with pH value five. Also, the colour of the litmus paper or
litmus strip is configured to change differently for both the pH value.
[0059] In an illustrative embodiment, the predetermined range between seven to fourteen
indicates basic nature of the fluid in increasing order. For example, when the fluid with basic
nature and pH value of nine falls on the litmus content or litmus paper, or the litmus strip, the
litmus paper or the litmus strip changes colour 104 due to the basic nature of the fluid. Similarly,
when the fluid with basic nature with pH value of twelve falls on the litmus content or litmus
paper, or the litmus strip, the litmus paper or the litmus strip changes colour 104 due to the basic
nature of the fluid. The fluid with pH value twelve is more basic than the fluid with pH value
nine. Also, the colour of the litmus paper or litmus strip is configured to change differently for
both the pH value. In another illustrative embodiment, the fluid can include any or a combination
of blood during menstrual cycle, white discharge, red discharge, and the likes associated with the
subject.
[0060] In an illustrative embodiment, the predetermined range for seven indicates neutral
nature of the fluid in increasing order. For example, when the fluid with neutral nature with pH
value of seven falls on the litmus content or litmus paper, or the litmus strip, the litmus paper or
the litmus strip changes colour 104 due to the neutral nature of the fluid. Similarly, when the
fluid with neutral or slightly alkaline or basic nature with value of eight falls on the litmus
content or litmus paper, or the litmus strip, the litmus paper or the litmus strip changes colour104
due to the neutral, slightly alkaline or basic nature of the fluid. The fluid with pH value seven is
11
more neutral than the fluid with pH value eight. Also, the colour of the litmus paper or litmus
strip is configured to change differently for both the pH value.
[0061] In an illustrative embodiment, when the blood of the menstrual cycle falls on the
litmus content, the litmus content can be configured to detect the pH value of the blood and
correspondingly changes colour 104 of the sheet 100. In another illustrative embodiment, the
nature of the blood during menstrual cycle is basic, and therefore the litmus paper or the litmus
strip changes colour 104 accordingly. In yet another illustrative embodiment, when the white
discharge from vaginal slot falls on the litmus content or litmus paper or litmus strip, due to the
basic nature, the colour of the litmus paper changes. The change in colour 104 of the litmus
content can be monitored by the second portion of the sheet including the monitoring unit 106.
[0062] In an embodiment, the second portion can include the monitoring unit 106 configured
to extract a set of detection signals based on the changed colour, where the set of detection
signals can pertain to pH parameters. In another embodiment, the monitoring unit 106 can be
configured to compare the pH parameters with a data set, where the data set can pertain to
predefined limit ranges. In yet another embodiment, the monitoring unit 106 can be configured to
generate a first set of alert signals108 when at least one of the pH parameters is found beyond the
predefined limit ranges. The monitoring unit 106 can include one or more processors coupled
with a memory, and the memory storing instructions executable by the one or more processors.
The monitoring unit 106 can be configured to receive the first set of electrical signals and the
second set of electrical signals from the first set of sensors and the second set of sensors
respectively.
[0063] In an embodiment, the monitoring unit 106 can be configured to generate a second set
of alert signals 110, when at least one of the pH parameters is found within the predefined limit
ranges. In another embodiment, the generated first set of alert signals 108 and the second set of
alert signals 110 by the monitoring unit 106 can be different. The monitoring unit 106 can
include the vibration circuit, where the vibration circuit can be configured to generate vibrations
based on the first set of alert signals108 and the second set of alert signals 110, and where the
generated vibrations facilitates in alerting the subject for start and end of the menstrual cycle. In
yet another illustrative embodiment, the first set of alert signals108 and the second set of alert
signals 110 are different.

NOR gates. The digital comparator can be configured to accept the extracted pH parameters
associated with the changed colour of the litmus content in the machine readable form. Further
three conditions can be applied for the comparison of the extracted pH parameters with the
predefined limit ranges.
16
[0079] In an illustrative embodiment, the three conditions associated with the digital
comparator can include a first condition, which can prevail when the extracted pH parameters are
found equal to the predefined limit ranges. A second condition can prevail when the extracted pH
parameters are found beyond the predefined limit ranges, and the third condition can prevail
when the extracted pH parameters concentrations are found within the predefined limit ranges.
The digital comparator can compare and transmit the compared pH parameters to the signal
generation unit 216 in the machine readable form.
[0080] In an illustrative embodiment, the predefined limit range can include a value from a
pH scale ranging from zero to seven. The threshold values stored in the database 210 can include
the value seven to compare the extracted pH parameters. In another illustrative embodiment,
when the extracted pH parameters received from the extraction unit 212 to the comparison unit
214 are found beyond the value seven, the compared pH parameters are transmitted to the signal
generation unit 216. The extracted pH parameters found beyond the value seven indicates
alkalinity or basicity in the blood of the subject during menstrual cycle. In yet another illustrative
embodiment, the comparison unit 214 can facilitate in comparing the extracted pH parameters
with the threshold value seven. The extracted pH parameters can include pH value of seven or
six, which can indicate that the compared pH parameters are within the predefined limit ranges.
The compared pH parameters within the predefined limit ranges can be transmitted to the signal
generation unit 216.
[0081] In an illustrative embodiment, the compared colour parameters, blood parameters,
progesterone hormonal parameters, and the oestrogen hormonal parameters along with the
viscous fluidic parameters by the comparison unit 214 can be transmitted to the signal generation
unit 216.
[0082] In an illustrative embodiment, the monitoring unit 106 can include a vibration circuit
configured to generate vibrations based on first set of alert signals and second set of alert signals.
[0083] In an embodiment, the signal generation unit 218 can facilitate generation of a first
set of alert signals 108 when at least one of the pH parameters are found beyond the predefined
limit ranges. In an illustrative embodiment, when the signal generation unit 218 receives the
compared pH parameters in machine readable form from the comparison unit 216, such that the
compared pH parameters are found beyond the predefined limit ranges, the signal generation unit
218 can be configured to generate the first set of alert signals 108. In another illustrative
17
embodiment, the first set of alert signals 108 generated can be transmitted to vibration circuit.
The vibration unit can be configured to generate vibrations based on the received first set of alert
signals 108.The vibrations can be transmitted to the subject via the sheet 100, where the sheet
100 can be configured with the subject’s bottom wear, lingerie, inner wear, and the likes. The
vibrations generated by vibration circuit with help of the first set of alert signals 108 can
facilitate the subject to become aware for beginning of menstrual cycle.
[0084] In an illustrative embodiment, the signal generation unit 216 can facilitate in
generating a second set of alert signals 110 when at least one of the pH parameters are found
within the predefined limit ranges. The signal generation unit 216 can be configured to receive
the compared pH parameters from the comparison unit 214 in machine readable form. When the
received compared pH parameters are found within the predefined limit ranges, the signal
generation unit 216 can facilitate generation of the second set of alert signals 110. The second set
of alert signals 110 generated can be transmitted to the vibration circuit in form of the vibrations.
The first set of alert signals 108 and the second set of alert signals 110 generated by the signal
generation unit 216 can be different. The vibration unit can be configured to generate vibrations
based on the received second set of alert signals 110.The vibrations generated by the vibration
circuit with help of the second set of alert signals 110 can be transmitted to the subject via the
sheet 100, where the sheet 100 can be configured with the subject’s bottom wear, lingerie, inner
wear, and the likes. The vibrations generated by the vibration circuit with the help of second set
of alert signals 110 can facilitate the subject to become aware for ending of menstrual cycle.
[0085] FIG. 3 illustrates overall components of the proposed alerting sanitary sheet for
menstrual cycle, in accordance with an embodiment of the present disclosure.
[0086] As illustrated in FIG.3, the proposed sheet 100 can include a sticky portion 302, an

[0087] In an illustrative embodiment, the first portion 102 with the litmus content can be
configured to detect potential for hydrogen (pH) of the fluid like blood during menstrual cycle
and white discharge, and can correspondingly change colour 104.In another illustrative
embodiment, when the blood comes out from vaginal slot during menstrual cycle, the blood
drops on the sheet 100, and especially first portion 102 with the litmus content. The litmus
content due to basic nature of the menstrual blood is configured to change colour104. The
monitoring unit 106 can be configured to identify the changed colour104 of the first portion 102
of the sheet 100. The monitoring unit 106 can be configured to generate a first set of alert signals
108. The first set of alert signals 108 can be transmitted to the vibration circuit, where the
vibration circuit can be configured to generate vibrations. The vibrations generated by the
vibration circuit can alert the subject for menstrual cycle beginning or the beginning phase of the
menstrual cycle. The subject can accordingly take precautions and use sanitary stuffs like
sanitary pads, menstrual cups, tampons, and the likes.
[0088] In an illustrative embodiment, during period of the menstrual cycle, the subject can
use the sanitary stuffs after receiving the first set of alert signals 108 as the vibrations.
Thereafter, after some days when the blood during menstrual cycle does not falls from the
vaginal slot, the first portion 102 does not receive any blood spot. The first portion 102 with the
litmus content does not changes colour and the monitoring unit 106 can be configured to
generate the second set of alert signals 110. The second set of alert signals 110 can be
transmitted to the vibration circuit and the vibration circuit can be configured to generate
vibrations. In another illustrative embodiment, the vibrations generated by the vibration circuit
with help of the second set of alert signals 110 can indicate the subject for ending phase of the
menstrual cycle, and accordingly the subject can take necessary steps like removing of the
sanitary stuffs. The vibrations generated by the vibration unit can further facilitate in ensuring
that the sanitary stuffs are not wasted and the subject uses the sanitary stuffs only when required.
As the subject is alerted by the vibrations generated by the vibration circuit, the subject can know
the exact time of starting and ending of the menstrual cycle.
[0089] In an illustrative embodiment, the sheet 100 can include a first set of sensors and a
second set of sensors. The first set of sensors can include any or a combination of colour sensor,
pH sensor, blood sensor, oestrogen sensor, progesterone sensor, and the likes. The second set of
sensors can include viscosity sensor and fluid sensor. In another illustrative embodiment, the first
19
set of sensors can be configured to detect colour parameters, blood parameters, progesterone
hormonal parameters, oestrogen hormonal parameters, pH parameters, and the likes, and can
generate a first set of electrical signals. The first set of electrical signals can be transmitted to the
monitoring unit 106. In yet another illustrative embodiment, the second set of sensors can be
configured to detect viscous fluidic parameters, and can generate a second set of electrical
signals 110. The second set of electrical signals 110 can be transmitted to the monitoring unit
106.
[0090] In an illustrative embodiment, the first set of alert signals 108 and the second set of
alert signals 110 generated by the monitoring unit 106 are different. The vibrations generated for
the starting phase of the menstrual cycle and the vibrations generated for the ending phase of the
menstrual cycle are different. The different vibrations can facilitate in alerting subject for
menstrual cycle and accordingly the subject can take precautions. In another illustrative
embodiment, the different vibrations can aid the subject in preventing vaginal infections, gynec
diseases, itchiness, rashes at private parts of the subject, that can be caused due to extended
usage of the sanitary stuffs.
[0091] In an illustrative embodiment, the sheet 100 can be configured as patch, membrane,
thin lining, and strip. In another illustrative embodiment, the sheet can include a power source
configured to supply electric power, and where the power source can include any or a
combination of battery, and cell. In yet another illustrative embodiment, the generated vibrations
can also facilitate in alerting the subject for unusual white discharge with highly basic nature,
and the subject can accordingly take precautions and use sanitary stuffs like panty liners to avoid
