The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[0001] The present disclosure relates to a technique of validating at least one
safety gear for a safety critical environment.
BACKGROUND
[0002] Safety of safety personnel/workers is a predominant factor in industries
from business and humanitarian perspectives. The injury to safety personnel/workers at workplace may cause disturbing effect to productivity and raise frustration in the workforce.
[0003] Generally, industry workforce is working in inhospitable locations such
as chemical-warehouse, manufacturing shop floors, inventory stores etc. Factories are rife with hazards, e.g. a worker may unknowingly walk into a welding zone or an area with fast moving conveyer belts or a high voltage area or a zone earmarked for poisonous chemicals. In addition to these types of static hazards, the nature of production may present dynamic hazards. For example, a worker might be standing in a perfectly safe area when a crane moves in with a block of steel positioned right above his head. To avoid such situations, different industries implement certain safety and security practices which includes wearing safety gears while at work. However, workers are casual and do not wear safety gears which results in accidents. In order to identify these kinds of precarious situations, it is necessary to validate and confirm if the workers are wearing safety gears when required.
[0004] Further, there is no such solution that detects damage in safety gears
which can cause a severe unfortunate accident with any worker. Damages like cracks in the safety gears, patches on the safety gears, wear and tear of the safety gears, color change in the safety gears due to chemical reactions can be harmful for the workers.

[0005] Therefore, there always existed a need in the art to provide a technique
which overcomes the above-mentioned problems by validating the safety gears and at the same time is capable of detecting damage in the safety gears.
SUMMARY
[0006] The present disclosure overcomes one or more shortcomings of the prior
art and provides additional advantages discussed throughout the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.
[0007] In one non-limiting embodiment of the present disclosure, a method of
validating at least one safety gear for a safety critical environment. The method comprises the steps of detecting at least one safety gear carried by a safety personnel and determining whether the at least one detected safety gear comprises at least one pre-defined safety gear. The at least one pre-defined safety gear comprises one or more safety gears mandatory for the safety personnel to access the safety critical environment. The method further comprises the steps of capturing at least one image of the at least one detected safety gear, if the at least one detected safety gear comprises the at least one pre-defined safety gear and processing the at least one captured image for detecting at least one damage in the at least one detected safety gear. The processing comprises the steps of categorizing the at least one detected safety gear into one or more categories of safety gears and for a particular category of safety gear, comparing the at least one captured image with a plurality of pre-stored images corresponding to said particular category for detecting the at least one damage. The method then displays the at least one detected damage in the at least one detected safety gear.
[0008] In another non-limiting embodiment of the present disclosure, a system
for validating at least one safety gear for a safety critical environment. The system comprises a detection unit configured to detect at least one safety gear on a safety personnel and a processing unit operatively coupled to the detection unit and configured to determine whether the at least one detected safety gear comprises at least

one pre-defined safety gear. The at least one pre-defined safety gear comprises one or more safety gears mandatory for the safety personnel to access the safety critical environment. The system further comprises an image capturing unit operatively coupled to the processing unit and configured to capture at least one image of the at least one detected safety gear, if the at least one detected safety gear comprises the at least one pre-defined safety gear. Further, the processing unit is configured to process the at least one captured image for detecting at least one damage in the at least one detected safety gear by categorizing the at least one detected safety gear into one or more categories of safety gears and for a particular category of safety gear, comparing the at least one captured image with a plurality of pre-stored images corresponding to said particular category for detecting the at least one damage. The processing unit is configured to enable display of the at least one detected damage in the at least one detected safety gear.

DETAILED DESCRIPTION
[0017] The terms “comprises”, “comprising”, “include(s)”, or any other
variations thereof, are intended to cover a non-exclusive inclusion, such that a setup, system or method that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or system or method. In other words, one or more elements in a system or apparatus proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or apparatus.

[0018] In the following detailed description of the embodiments of the
disclosure, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
[0019] Fig. 1 shows a flow chart illustrating an exemplary method 100 of
validating at least one safety gear for a safety critical environment, in accordance with an embodiment of the present disclosure.
[0020] At block 101, at least one safety gear carried by a safety personnel may
be detected using a detection unit. Each of the at least one safety gear may comprise a Radio Frequency (RF) tag or a Bluetooth tag comprising an Electronic Product Code (EPC). The EPC code may be associated with an item number and name of the safety gear and stored in the database or memory of the system. The EPC codes may provide a unique identifier for every safety gear. The detection unit may comprise an RF reader or a Bluetooth reader for reading or detecting the EPC codes of the RF tag and Bluetooth tag, respectively. In one embodiment of the preset disclosure, the detection unit may be located or installed at the entrance door of a safety critical environment.
[0021] At block 103, the at least one detected safety gears at block 101 may be
matched with at least one pre-defined safety gears to determine whether the detected safety gear comprises the at least one pre-defined safety gear. The at least one pre-defined safety gear may comprise one or more safety gears mandatory for the safety personnel to access the safety critical environment. In one embodiment of the present disclosure, the one or more mandatory safety gears may vary from industry to industry.
[0022] For example, the mandatory safety gears may be selected based on the
type of industry. In another example, the mandatory safety gears may be selected based on the hazardous conditions present in the industry. In another example, the mandatory

safety gears may be selected based on the location of the industry. In another example, the mandatory safety gears may be selected based on the number of workers in the industry. In yet another example, the mandatory safety gears may be selected based on safety and security practices mandatory for the industry. For example, for a chemical industry, a mask, eye-glasses, and a vest may be considered as mandatory safety gears. For a cement industry, a helmet, a mask, and eye-glasses may be considered as mandatory safety gears.
[0023] If the at least one detected safety gear does not comprise the pre-defined
safety gears, the safety personnel are not allowed to access the safety critical environment. If the at least one detected safety gear does not comprise the at least one pre-defined safety gear, a notification may also be sent to a supervisor of the respective safety personnel and the absent safety gear may also be displayed on the dashboard of the supervisor.
[0024] In one embodiment of the present disclosure, the detection of at least
one safety gear on a safety personnel may also comprise detection of a unique identifier associated with the at least one safety gear. The unique identifier may be present in the EPC code detected by the detection unit. In response to detection of the unique identifier associated with the at least one safety gear, the method 100 may determine whether the at least one detected safety gear is allocated to the safety personnel based on the detected unique identifier. If the at least one detected safety gear is not allocated to the safety personnel, a notification that the at least one detected safety gear is not allocated to the safety personnel by displaying on the dashboard of the supervisor of the safety personnel.
[0025] At block 105, if the at least one detected safety gear comprises at least
one pre-defined mandatory safety gear, at least one image of the at least one detected safety gear is captured using an image capturing unit. In one embodiment, the image capturing unit may comprise one or more cameras located at the entrance door or anywhere near the entrance of safety critical environment. The image capturing unit may capture one or more images of the respective safety gear.

[0026] At block 107, the at least one captured image is processed for detecting
at least one damage in the at least one detected safety gear. The processing may comprise categorizing the at least one detected safety gear into one or more categories of safety gears. For example, a safety gear may be categorized into various categories such as helmet, eyeglasses, vest, shoes, mask, etc. The processing may further comprise, for a particular category of safety gear, comparing the at least one captured image with a training data set of a particular safety environment in which the at least one safety gear is used. The training data set may include a plurality of pre-stored images corresponding to the particular category.
[0027] In one embodiment, the plurality of pre-stored images may include
images of different safety gears for different safety critical environments. In another embodiment, the plurality of pre-stored images may include images of different safety gears under different conditions defining the usage and life span of the safety gears. In yet another embodiment, the plurality of pre-stored images may indicate the type of damage and the extent of damage in the safety gears under different operating conditions for different safety critical environments. In an embodiment, the training data set may be updated on a periodic basis. The at least one captured image of the at least one safety gear is compared with the training data set to determine at least one damage in the at least one safety gear.
[0028] At block 109, if the at least one damage is detected in the at least one
safety gear, the at least one damage is displayed. In other words, one or more portions of the safety gears that are damaged are displayed. In an embodiment, the identified portions of the at least one safety gear that are damaged highlighted and displayed on the dashboard of the supervisor. The at least one damage in the at least one detected safety gear may comprise at least one of: a crack in the at least one detected safety gear, a patch on the at least one detected safety gear, or wear and tear of the at least one detected safety gear.
[0029] After the identification of the at least one damage in the at least one
safety gear, the parameters of the damage such as length, breadth, depth in case of

cracked safety gear, or pigmentation or color change in case of burnt safety gear to calculate the percentage of damage are determined. The parameters of the damage such as length, breadth and depth may be determined based on the comparison with the training data set defined above. After the parameters are calculated, the parameters are compared with respective threshold values to determine whether the damage is within permissible limit or not. If the damage is within permissible limit, the safety gear may be used again. If the damage is out of permissible limit, the safety gear may not be used again.
[0030] In an embodiment of the present disclosure, the method may further
comprise determining whether the at least one detected damage is present in the at least one pre-defined safety gear. If the at least one damage is present in the at least one pre-defined safety gear the method comprises restricting access to the safety critical environment.
[0031] In another embodiment of the present disclosure, the detection of
damage in the safety gears may be further examined. The damage patterns may be analyzed which may help in maintaining the safety gears. The damage patterns may be according to life of the safety gear, the number of times it is being used and the number of users assigned to a particular safety gear. Also, if the damage in a particular type of safety gear is frequent then the reports can be used to focus on that particular type and to intimate the vendors about the damage of the safety gears. The steps of method 100 may be performed in an order different from the order described above.
[0032] Fig. 2 shows a block diagram illustrating a system for validating at least

hardware for implementing a neural network. The neural network may comprise a plurality of layers.
[0034] The detection unit 201 may be configured to detect at least one safety
gear on a safety personnel. The detection unit 201 may comprise an RF reader or a Bluetooth reader for reading or detecting the EPC codes of the RF tag and Bluetooth tag present on the at least one safety gear, respectively. The EPC codes may provide a unique identifier for every safety gear. The detection unit may be located or installed at the entrance door of a safety critical environment. In one non-limiting embodiment of the present disclosure, the detection unit 101 is not limited to above mentioned examples. Any other detection unit for detecting unique identifier is well within the scope of the present disclosure.
[0035] The detection unit 201 may also be configured to detect at least one
safety gear on a safety personnel by detecting a unique identifier associated with the at least one safety gear. The unique identifier may be present in the EPC code detected by the detection unit. In response to detection of the unique identifier associated with the at least one safety gear, the processing unit 203 may be configured to determine whether the at least one detected safety gear is allocated to the safety personnel based on the detected unique identifier. If the at least one detected safety gear is not allocated to the safety personnel, the processing unit 203 may be configured to enable display of a notification that the at least one detected safety gear is not allocated to the safety personnel on the dashboard of the supervisor of the safety personnel. The display device 207 may be configured to display the notification on the dashboard of the supervisor.
[0036] The processing unit 203 may be configured to determine whether the at
least one detected safety gear includes at least one pre-defined safety gear as discussed above. The at least one pre-defined safety gear comprises one or more safety gears mandatory for the safety personnel to access the safety critical environment. If the at least one detected safety gear does not comprise the pre-defined safety gears, the processing unit 203 may be configured to restrict the safety personnel to access the

safety critical environment. If the at least one detected safety gear does not comprise the at least one pre-defined safety gear, the processing unit 203 may be configured to send a notification to a supervisor of the respective safety personnel and the absent safety gear may also be displayed on the dashboard of the supervisor.
[0037] If the at least one detected safety gear comprises the at least one pre-
defined safety gear, the image capturing unit 205 may be configured to capture at least one image of the at least one detected safety gear. In one embodiment, the image capturing unit may comprise one or more cameras located at the entrance door or anywhere near the entrance of safety critical environment. The image capturing unit 205 may capture one or more images of the respective safety gear.
[0038] The processing unit 205 may be configured to process the at least one
captured image for detecting at least one damage in the at least one detected safety gear. The processing may comprise categorizing the at least one detected safety gear into one or more categories of safety gears. For example, a safety gear may be categorized into various categories such as helmet, eyeglasses, vest, shoes, mask, etc. The processing may further comprise, for a particular category of safety gear, comparing the at least one captured image with a training data set of a particular safety environment in which the at least one safety gear is used. The training data set may include a plurality of pre-stored images corresponding to the particular category.
[0039] In one embodiment, the plurality of pre-stored images may include
images of different safety gears for different safety critical environments. In another embodiment, the plurality of pre-stored images may include images of different safety gears under different conditions defining the usage and life span of the safety gears. In yet another embodiment, the plurality of pre-stored images may indicate the type of damage and the extent of damage in the safety gears under different operating conditions for different safety critical environments. In an embodiment, the training data set may be updated on a periodic basis. The processing unit 203 may be configured to compare the at least one captured image of the at least one safety gear with the training data set to determine at least one damage in the at least one safety gear. The

processing unit 203 may be trained with the plurality of pre-stored images as mentioned above.
[0040] The processing unit 203 may be configured to enable display of the at
least one detected damage in the at least one detected safety gear on the display device 207. The processing unit 203 may be further configured to restrict access to the safety critical environment, if the at least one detected safety gear does not comprise the at least one pre-defined safety gear.
[0041] In another embodiment of the present disclosure, the processing unit
203 may be configured to determine whether the at least one detected damage is present in the at least one pre-defined safety gear and restrict access to the safety critical environment, in response to determining the at least one damage in the at least one pre¬defined safety gear.
[0042] In another embodiment of the present disclosure, the detection of
damage in the safety gears may be further examined. The processing unit 203 may be further configured to analyze damage patterns which may help in maintaining the safety gears. The damage patterns may be according to life of the safety gear, the number of times it is being used and the number of users assigned to a particular safety gear. Also, if the damage in a particular type of safety gear is frequent then the reports can be used to focus on that particular type and to intimate the vendors about the damage of the safety gears.
[0043] Fig. 3(a) shows an exemplary method 300 of determining a remaining
lifetime of a safety gear and fig. 3(b) shows block diagram of determining a remaining lifetime of a safety gear, in accordance with another embodiment of the present disclosure.
[0044] At block 301, at least one parameter from at least one sensor deployed
on the at least one detected safety gear may be received and stored in the memory of the system 200. The at least one parameter may be selected from the group comprising temperature, humidity and toxic gases. The at least one sensor may comprise a

temperature sensor, a humidity sensor, and a gas detector. The at least one parameter may be used to identify the environmental conditions in a safety critical environment where the safety personnel are working.
[0045] At block 303, at least one attribute associated with the at least one
detected safety gear is retrieved from the memory 209 of the system 200. The at least one attribute is selected from the group comprising usage details of the at least one detected safety gear, history of the accidents associated with the at least one detected safety gear and shelf-life of the at least one detected safety gear.
[0046] At block 305, a remaining lifetime of the at least one detected safety
gear may be determined based on at least one of at least one parameter, at least one attribute and the at least one detected damage in the at least one detected safety gear as mentioned in method 100 above.
[0047] In an exemplary embodiment of the present disclosure, the remaining
life of the safety gear may be calculated as shown in fig. 3(b). As discussed in method 300, the remaining lifetime of the safety gear may be calculated based on at least one of at least one parameter, at least one attribute and the at least one detected damage by image processing. The at least one parameter may indicate the usage environment of the safety gear. The at least one attribute may comprise life or shelf-life of the product/safety gear, usage details or history of products, and accident history of the product. Thus, the remaining lifetime of the safety gear or the product may be calculated based on the parameters comprising life of the product, usage environment, history of product, accident history, and image processing result. The parameters may change as per the industry requirement.
[0048] As shown in figure 3(b), each of the parameters may be give a respective
weightage in calculation of the remaining lifetime. The parameters and the weightage may be configurable and aligned with expected output in a neural network as shown in fig. 3(b). For example, life of product may be given 20 percent weightage, usage environment may be given 20 percent weightage, history of product may be given 10 percent weightage, accident history may be given 40 percent weightage, and image

processing result may be given 10 percent weightage. The output parameters of the neural network may comprise the prediction of accident, remaining life of a safety gear, maintenance and reusability of the safety gear.
[0049] The usage or history of the product may be calculated based on in and
out time of the worker using the safety gear. The life of the product may be given by manufacturer based on the environment (e.g. high temperature or humid condition) in which the product is operated. The life of the product may also specify the standard conditions in which the product may or may not work. For example, for a helmet standards it may be specified that the helmet may not work at a temperature of more than 100 degree Celsius and may work at temperature range 99 to 55 degree Celsius for 9 months.
[0050] In an embodiment of the present disclosure, the accident history may
comprise the accident patterns that are frequently being held with a particular safety gear in a particular safety critical environment. Image processing results may comprise at least one damage detected by real time image comparison with the training data set as discussed above in method 100. If value of any of the above mentioned parameter tends to zero, then the weightage of that parameter may be divided in proportion to maintain the overall percentage.
[0051] Fig. 4 illustrates a block diagram illustrating a system 400 for
monitoring health of the safety gear, in accordance with another embodiment of the present disclosure.
[0052] In an embodiment of the present disclosure, the system 400 may
comprise at least one sensor 401, a transceiver 403, a memory 405, and a processor 407 in communication with each other. The at least one sensor 401 may comprise a temperature sensor, a humidity sensor, and a gas detector. In one non-limited embodiment of the present disclosure, the at least one sensor 401 is not limited to above mentioned examples. Any other sensor for sensing environmental parameters of the safety critical environment is well within the scope of the present disclosure. The system 400 may be deployed on the at least one safety gear.

[0053] The at least one sensor 401 is configured to detect at least parameter of
the safety critical environment. The processor 407 of the system 400 may store the at least parameter in the memory 405. The processor 407 may also be configured to transmit, via the transceiver 403, the at least one parameter to the interface unit 201 of the system 200. The system 200 may be configured to calculate the remaining life of the safety gear as mentioned above.
[0054] Fig. 5(a)- 5(e) illustrates an exemplary method of validating at least one
safety gear for a safety critical environment, in accordance with another embodiment of the present disclosure.
[0055] In an embodiment of the present disclosure, the method of validating at
least one safety gear for a safety critical environment may comprise three step validation system. In the first step, the detection unit 201 present at the entrance of the safety critical environment may be configured to detect at least one safety gear worn by the safety personnel. The detection unit may read EPC codes present on the RF tag or Bluetooth tags. The detected safety gears are then compared with the pre-defined list of mandatory safety gears for a particular safety critical environment, to determine whether all the mandatory safety gears are present or not.
[0056] If all the mandatory safety gears are present, the detected list of safety
gears are displayed on the dashboard of the supervisor of the safety personnel as shown in fig. 5(a). If all the mandatory safety gears are not present, the absent safety gear is highlighted and access to the safety critical environment is denied as shown in fig. 5(b).
[0057] In the second step, if all the mandatory safety gears are present, the
image capturing unit 205 present at the entrance of the safety critical environment may be configured to capture at least one image of the at least one detected safety gear. The at least one captured image is processed to detect a damage in the at least one safety gear. The processing of the at least one captured image may be done by comparing the captured image with the training data set as mentioned above.

[0058] If at least one damage is detected in the at least one safety gear, a
notification is displayed on the dashboard of the supervisor as shown in fig. 5(c) and access to the safety critical environment is denied. In the third step, if at least one damage is detected in the at least one safety gear, the digital image processing algorithm is used to identify the portion of the safety gear which is damaged and display device 207 may be further configured to highlight and display the damaged portion as shown in fig. 5(d).
[0059] In another embodiment of the present disclosure, the processing unit
203 may detect the percentage of damage in the at least one safety gear based on the parameters of the damaged portion. Fig. 5(e) indicates crack in the helmet and parameters related to the crack. For example, parameter may comprise length (which is 7cm in this case), breadth (which is 90mm in this case) and depth (which is 50mm in this case) are calculated based on comparison of captured image with the training data set as mentioned above. After the parameters are calculated, the parameters are compared with respective threshold values to determine whether the damage is within permissible limit or not. If the damage is within permissible limit, the safety gear may be used again. If the damage is out of permissible limit, the safety gear may not be used again. In one non-limiting embodiment of the present disclosure, the damage may be verified by QA person.
[0060] The interface unit 210 may include at least one of a key input means,
such as a keyboard or keypad, a touch input means, such as a touch sensor or touchpad, a transceiver, a sound source input means, a camera, or various sensors, and the user interface may include a gesture input means. Further, the interface unit 210 may include all types of input means that are currently in development or are to be developed in the future. The interface unit 210 may receive information from the user through the touch panel of the display and transfer the inputted information to the processing unit and one or more processors.
[0061] The processing unit 203 may comprise one or more processors,
memory, and communication interface. The memory may be software maintained

and/or organized in loadable code segments, modules, applications, programs, etc., which may be referred to herein as software modules. Each of the software modules may include instructions and data that, when installed or loaded on a processor and executed by the processor, contribute to a run-time image that controls the operation of the processors. When executed, certain instructions may cause the processor to perform functions in accordance with certain methods, algorithms and processes described herein.
[0062] The illustrated steps are set out to explain the exemplary embodiments
shown, and it should be anticipated that ongoing technological development will change the manner in which particular functions are performed. These examples are presented herein for purposes of illustration, and not limitation. Further, the boundaries of the functional building blocks have been arbitrarily defined herein for the convenience of the description. Alternative boundaries can be defined so long as the specified functions and relationships thereof are appropriately performed.
