METHOD AND SYSTEM FOR INTOXICATION EXAMINATION OF OPERATORS FOR ASSET OPERATION AUTHORIZATION

TECHNICAL FIELD

Generally, the invention relates to intoxication examination and more specifically, to a method and system for intoxication examination of an operator for operating an asset.

BACKGROUND

Alcohol and Drugs Abuse (ADA) has been a major concern in our society, on the roads, and at workplaces. In our society, more than 40% of people are reported to consume alcohol and other substances. On the roads, Driving Under the Influence (DUI) is a major cause of road accidents and subsequent loss of life and damage to properties. Many governments across the world have framed regulations and guidelines to deal with the problem of Alcohol and Drugs Abuse (ADA). The World Health Organization (WHO) has recommended a general guideline to member countries for DUI countermeasures. Recommendations include enacting and enforcing laws for BAC limits and penalties for DUI. As a result, encouraging results have been observed in many countries on measures taken to reduce a number of alcohol-impaired drivers by enacting stricter laws with higher penalties and fines. Data gathered also showed gradual reduction in number of deaths due to various road safety measures including increased use of seat belts, manage speed limits, and reduced number of alcohol-impaired drivers in traffic. For example, the mandatory Ignition Interlock Device (IID) program is introduced in some countries for DUI offenders.

Further, for example, a “Safe Driving Manager System” is introduced in Japan for all enterprises operating 5 or more vehicles. A “Driver Alcohol Detection System for Safety (DADSS)” that is a public-private partnership program between the “Automotive Coalition for Traffic Safety (ACTS) and National Highway Traffic Safety Administration (NHTSA)” have been launched with the aim to develop alcohol detection systems that may passively and unobtrusively detect driver's Blood Alcohol (BAC) level and prevent from driving when it is above a legal limit. At the workplaces, Alcohol and Drugs Abuse (ADA) poses serious issues to businesses including injury to self and others, productivity loss, damage to property, compensations, liabilities, increased insurance cost, litigations, and the like.

Various systems are available for intoxication examination that may perform intoxication monitoring based on breath air analysis or sensing through skin, drowsiness and alertness monitoring based on eyes activities, operator identification based on biometric and visual recognition, allowing machine operation based on intoxication levels assessment, and safety compliance monitoring while operating a machine. The available systems have solved variety of problem areas with general objective to improve safety of the operator (i.e., a user), properties, and in many cases other people (i.e., co-passengers, pedestrians, co-workers, and public) too. However, the available systems still lack in providing solutions for the enterprises in creating and maintaining a drug free workplace.

Referring now to FIG. 1, a system 100 for intoxication examination of an operator 102 for operating an asset is illustrated, in accordance with some embodiments of the present disclosure. The system 100 includes an operator 102, a manager 104 or an administrator, an intoxication examination module 106, and an asset operation authorization 108, and an asset access control module 110. The intoxication examination module 106 may perform an intoxication examination of the operator 1, 2 and based on that enables the system 100 to decide whether the operator is able to operate the asset. In an embodiment, the intoxication may be a self-examination test 106a. In an embodiment, the intoxication examination may be a video call examination 106b. In an embodiment, the intoxication examination may be an in-person examination 106c.

The system 100 may include a client-side device (not shown in FIG. 1) and a centralized server (not shown in FIG. 1). In some embodiments, the client-side device may enable an operator 102 to perform the self-examination test 106a. The centralized server may enable a manager/administrator 104 to review the self-examination test 106a taken by the operator 102. The client-side device may have a processor capable of running a client-side self-examination module, a display and a keyboard to interact with the operator 102, a video camera to capture a video while performing the self-examination test 106a, an intoxication detection device to measure presence of alcohol or drug, a data store, and network connectivity with the centralized server. The client-side device may include, but is not limited to, a smartphone, a laptop, a computer; any device integrated with the asset, a Digital Instrument Cluster (DIC) or the like.

Further, the centralized server may have a processor capable of running a server-side self-examination module, a display and a keyboard to interact with the operator 102, and a data store. The server may be an on-premises hosted or a cloud-hosted accessible from a workstation, a computer, a laptop, or the like. The system may also include an identity repository to store operator's and manager's/administrator's information. The identity repository may securely store operator credentials (for example, the login credentials). Also, in some embodiments, an Identity and Authorization Management (IAM) system may be used to enable Single Sign-On (SSO) and Multi-Factor Authentication (MFA), in place of the identity repository.

Further, the client-side device may require the operator 102 to sign-in using the credentials maintained in the identity repository. The client-side device may require a sign-in by the operator 102 if the operator's access is for the first time to establish network connectivity with the server for authentication. Once the operator 102 successfully signed-in, a hash of the credentials is securely stored in a cache that enables the operator 102 to sign-in again even if the client-device is not connected to network.

The client-side device may enable the operator 102 to initiate the self-examination test 106a and turn on the video camera for evidence recording. The operator 102 may be expected to remain within the video frame for entire duration of recording (i.e., from beginning to end). The client-side device may require the operator 102 to perform an operator verification through a biometric test and/or Identification Document (ID) verification. The biometric test may include, but is not limited to facial recognition, fingerprint matching, voice recognition, retina scanning, and the like. In some embodiments, the operator 102 may be allowed to use a valid ID proof issued by an employer (such as, an employee ID card), and a valid ID proof issued by a government agency (such as a driving license). In some embodiments, an Optical Character Recognition (OCR) technique, a barcode, and a QR Code may be used for ID verification.

The client-side device may require the operator 102 to perform a test using an intoxication detection device. The intoxication detection device may include a breath-based device (such as a breathalyzer), a touch-based device (such as an Alcometer), or a blood-based or saliva-based test-kit.

Further, in some embodiments, the client-side device may enable the operator 102 to initiate the video call examination 106b with the manager/administrator 104. The centralized server may enable the manager/administrator 104 to accept a video call from the operator 102, oversee the examination, and provide approval to operate the asset. The processor of the client-side device may be capable of running a client-side video-call examination module, a display and a keyboard to interact with the operator 102, a video camera for the video call, the intoxication detection device (such as the breathalyzer or the alcometer) to measure presence of alcohol and drug, and the network connectivity with the centralized server. The client-side device may be the smartphone, the computer; the laptop, the device integrated with the asset (e.g., the DIC), or the like.

The processor of the centralized server may be capable of running a server-side video-call examination software module, the display and the keyboard to interact with the operator 102, and the datastore. The server may be the on-premises hosted server or the cloud-hosted accessible from the workstation, the computer, the laptop, and the like. Further, the identity repository may be used to store the operator's and manager's/administrator's information. The identity repository securely stores the operator's credentials. In some embodiments, the identity repository may be replaced with the IAM system used to enable SSO and MFA.

The client-side device may require the operator 102 to sign-in using the credentials maintained in the identity repository. The client-side device may enable the operator 102 to initiate the video call with the manager/administrator 104. The centralized server may enable the manager 104 to accept the video call from the operator 102. The manager/administrator 104 may join the video call. The operator 102 may be expected to remain within the video frame for entire duration of video call from beginning to end.

In some embodiments, the client-side device may require the operator 102 to perform the biometric identification test and/or the ID verification. The biometric identification test may be performed based on at least one of the facial recognition techniques, the fingerprint matching, the voice recognition technique, and the retina scanning. The operator 102 may be allowed to use a valid ID proof issued by the employer (such as an employee ID card), valid ID proof issued by the government agency (such as the driving license, the voter ID). In some embodiments, at least one of the OCR techniques, the barcode, or the QR code may be used for the ID verification.

The client-side device may require the operator 102 to perform a test using the intoxication detection device. The intoxication detection device may include the breath-based device (such as the breathalyzer), the touch-based device (such as the alcometer), the blood-based or saliva-based test-kit, and the like.

In some embodiments, the client-side device may require the operator 102 to complete an examination questionnaire. The examination questionnaire may include questions and puzzles to assess the physical and mental fitment of the operator 102 required to safely carryout the operation. The manager/administrator 104 may verify and approve/reject the examination. It should be noted that the system 100 uses a plurality of business rules to check whether the operation is permissible. The business rules may factor the measurement from the intoxication detection device (such as breath alcohol content, blood alcohol content), and answers to the examination questionnaire. If the operation is permissible, the asset or a class of assets may be assigned to the operator 102. The asset assignation may be either done by the manager/administrator 104 or a self-assignation by the operator 102.

The asset may include the vehicle, the forklift, the crane, the aircraft, the watercraft, the machinery, and the like. Further, the asset operation authorization 108 may be generated and transmitted to the asset. The operation authorization 108 may include information of the operator, the asset or the class of asset, conditions of operation, validity period, the issuer, and checksum. The asset may verify the operation authorization 108 and allow the access to the operator 102.

The asset access control module 110 may be employed on the asset to validate the operation authorization 108, allow the operator 102 to access the asset, and ensure that the operation is performed as per predefined conditions of operation. It should be noted that logs of access and operations may be stored in an asset repository for compliance reporting and audit use. In some embodiments, the system 100 may save data to an examination repository. The data saved in the examination repository may include a recording of the video call examination 106b, measurements from the intoxication detection device, answers to the examination questionnaire, decision taken by the system 100 based on the business rules, and approval information by the manager/administrator 104. The manager/administrator 104 may review access to the asset. The manager/administrator may review the asset's access and operation's logs. Any discrepancy observed may be taken up as an input for further remedial actions and process improvements.

The in-person examination 106c may be implemented using the server-side system. The server-side system may enable the manager/administrator 104 to perform the in-person examination 106c with the operator 102. The server-side system may have the processor capable of running an in-person-examination module, the display and the keyboard to interact with the operator, the video camera for evidence recording, the intoxication detection device (such as the breathalyzer or the alcometer) to measure presence of alcohol and drug, and the datastore. The server of the server-side system may be the on-premises hosted or the cloud-hosted accessible from the workstation, the computer, the laptop, and the like. The operator 102 may in-person meet the manager/administrator 104. The manager/administrator 104 may turn on the video camera for evidence recording. The operator 102 may be expected to remain within the video frame for entire duration of examination from beginning to end.

The operator 102 may be required to perform the biometric identification test and/or the identity ID verification. The biometric identification test may be performed using at least one of the facial recognition techniques, the fingerprint matching, the voice recognition, the retina scanning, and the like. The operator 102 may be allowed to use the valid ID proof issued by the employer (such as the employee ID card) or valid ID proof issued by the government agency (such as the driving license). Further, the OCR, the barcode, and/or the QR Code may be used for ID verification.

Further, the operator 102 may be required to perform a test using the intoxication detection device. The intoxication detection device may include, but is not limited to, the breath-based device (for example, the breathalyzer), the touch-based device (for example, the alcometer), and the blood-based or the saliva-based test-kit. The manager/administrator 104 may verify and approve/reject the examination Further, the plurality of predefined business rules may be considered to decide whether the operation is permissible. The plurality of predefined business rules may factor measurement from the intoxication detection device (such as, breath alcohol content, and blood alcohol content), and answers to the examination questionnaire. If the operation is permissible, the manager 104 may be enabled to assign the asset or a class of the assets to the operator 102.

The asset may include the vehicle, the forklift, the crane, the aircraft, the watercraft, the machinery, or the like. Moreover, the asset operation authorization 108 may be generated and transmitted to the asset. The asset operation authorization 108 may include information of the operator, the asset or the class of assets, conditions of operation, validity period, the issuer, and checksum. The asset may verify the asset operation authorization 108 and allow the access to the operator 102. Further, the asset access control module 110 may be deployed on the asset to validate the asset operation authorization 108, allow the operator to access the asset, and ensure that the operation is performed as per the conditions of operation. Logs of access and operations may be stored in the asset repository for compliance reporting and audit use.

The system saves data to the examination repository. The examination data includes a recording of the in-person-examination, measurements from the intoxication detection device, answers to the examination questionnaire, decision taken by the system based on business rules, and approval information by the manager. The manager reviews access to the Asset. The manager reviews the asset's access and operations logs. Any discrepancy observed is taken up as input for further remedial actions and process improvements.

The system 100 provides proactive fitment screening of operators (for example, for employees) to carry out operations using the asset (i.e., a vehicle, a forklift, a crane, an aircraft, a watercraft, a machinery, and the like). In addition, the system 100 defines various workflows and approaches to perform the testing.

It should be noted that the systems 100, 200, 300 may be implemented in programmable hardware devices such as programmable gate arrays, programmable array logic, programmable logic devices, or the like. Alternatively, the systems 100, 200, 300 may be implemented in software for execution by various types of processors. An identified engine/module of executable code may, for instance, include one or more physical or logical blocks of computer instructions which may, for instance, be organized as a component, module, procedure, function, or other construct. Nevertheless, the executables of an identified engine/module need not be physically located together but may include disparate instructions stored in different locations which, when joined logically together, comprise the identified engine/module and achieve the stated purpose of the identified engine/module. Indeed, an engine or a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different applications, and across several memory devices.

As will be appreciated by one skilled in the art, a variety of processes may be employed for feature extraction from an input image from a plurality of images in an image sensor pipeline. For example, the systems 100, 200, 300 may perform an intoxication examination of an operator for operating an asset, by the process discussed herein. In particular, as will be appreciated by those of ordinary skill in the art, control logic and/or automated routines for performing the techniques and steps described herein may be implemented by the systems 100, 200, 300 either by hardware, software, or combinations of hardware and software. For example, suitable code may be accessed and executed by the one or more processors on the systems 100, 200, 300 to perform some or all of the techniques described herein. Similarly, application specific integrated circuits (ASICs) configured to perform some or all the processes described herein may be included in the one or more processors on the systems 100, 200, 300.

The system 100, 200, 300 may help enterprises in examining an operator for intoxication and fitness level before allowing the operator to operate an equipment. The system 100, 200, 300 may begin with establishing an operator's identity. The system 100, 200, 300 may enable the operator and operators' manager to carry out an intoxication examination that also includes a questionnaire to assess fitness of the operator. The system 100, 200, 300 may provide intoxication examination methods options suitable for different workplace scenarios including self-examination, video-call-examination, and in-person-examination. The system 100, 200, 300 may work with connected assets. In that case, the system 100, 200, 300 may generate an operation authorization and send to the asset assigned to the operator. The connected asset may control the access based on the operation authorization.

Referring now to FIG. 4, a process of intoxication examination of an operator for operating an asset is depicted via a flowchart 400, in accordance with some embodiments of the present disclosure. FIG. 4 is explained in conjunction with FIGS. 1-3.

At step 402, input data corresponding to the operator may be received by the server. The input data may be received prior to operating the asset from at least one of an asset or a client device. The input data may include an operator profile, video data of the operator, audio data corresponding to voice of the operator, and an intoxication level of the operator estimated using a plurality of intoxication examination devices. It should be noted that the asset may be in a locked state. Further, in the locked state, the asset may be inaccessible by the operator. The operator profile may include a number of past failed authorization attempts of the operator. Further, the video data of the operator may include at least one of a video recording of the operator undertaking an intoxication examination with each of the plurality of intoxication examination devices, and a video recording of the operator responding to one or more prompts via a User Interface (UI).

In some embodiments, a position and an orientation of each of the operator and an intoxication examination device may be identified with respect to video frame from the video data of the operator through the ML model. Further, in some embodiments, the operator may be notified to remain within the video frame when at least one of the operator and the intoxication examination device is out of the video frame. Additionally, in some embodiments, real-time recommendations or suggestions may be provided to the operator to continue remaining within the video frame.

It should be noted, in some embodiments, a login request from the operator prior to receiving the input data from the operator may be received by the server. The login request may be a general login request including login credential details of the operator. Further, validation of the login request may be required for further processing. Therefore, in some embodiments, the login request may be validated by the server based on the login credential details entered by the operator. In case, the login request validation is successful, a video of the operator may be recorded using a camera in real-time.

At step 404, an intoxication score of the operator may be determined by the server. The intoxication score may be determined based on the input data using a Machine Learning (ML) model. In some embodiments, an operator verification may be performed using the ML model. The operator verification may be based on a biometric identification test or an operator Identification Document (ID).

Thereafter, at step 406, a permissibility of operating an asset for the operator may be determined through a plurality of predefined rules by the server. This step may be performed using the ML model. In some embodiments, the intoxication score of the operator may be considered to check the permissibility. For example, the asset operation is permissible when the intoxication score of the operator is above a predefined threshold score required for operating the asset. In some embodiments, a plurality of responses corresponding to an examination questionnaire received from the operator may be considered for determining the permissibility. The examination questionnaire may include a plurality of questions. Further, the asset operation may be permissible when the operator correctly answers more than a predefined threshold number of questions in the questionnaire.

At step 408, the asset may be assigned by the server to the operator. The asset may be assigned when the asset operation is determined to be permissible for the operator. At step 410, authorization information may be transmitted to the assigned asset by the server. Here, the authorization information may include operator details, a class of the asset, conditions of operation, a validity period, an issuer, and checksum.

At step 412, the operator may be authorized by the asset to operate the asset based on the authorization information. Upon successful authorization, the asset may switch to an unlocked state from the locked state. It may be apparent to those skilled in the art that the unlocked state of the asset is accessible by the operator.

Thereafter, at step 414, upon authorization, the operator may be monitored by the server in real-time during the asset operation. Monitoring may be performed from real-time video data of the operator to check for compliance of the asset operation with the conditions of operation. In some embodiments, during monitoring, one or more anomalies in the asset operation may be identified. In case of identification of the one or more anomalies, a notification about the one or more anomalies may be transmitted to the operator, the administrator, and the server. Further, in some embodiments, the authorization of the operator to operate the asset may be revoked.

Additionally, in some embodiments, the input data, the real-time video data, and a number of failed authorization attempts by the operator may be stored in a historical dataset associated with the operator. Further, in some embodiments, a past behaviour record of the operator may be maintained in the operator profile based on the historical dataset associated with the operator using the ML model.

Referring now to FIG. 5, a method of operating an asset through a self-intoxication examination by the operator is depicted via a flowchart 500, in accordance with some embodiments of the present disclosure. FIG. 5 is explained in conjunction with FIGS. 1-4.

At step 502, an operator may send a sign in request (login request) to a server (for example, the centralized server 202) associated with the system. The sign in request may include credentials (such as login credentials). The operator may sign in using these credentials. If sign in details or credentials provided by the operator are correct or successfully validated by the server then the intoxication examination may get initiated. For example, in FIG. 5 a self-examination is explained, where the operator may perform the intoxication examination.

At step 504, the operator may turn on a camera. A video of evidence may be recorded using the camera. This video of evidence may be used further to check intoxication level of the operator. At step 506, operator verification may be performed based on a biometric identification test or an operator Identification Document (ID). A Machine Learning (ML) model may be used to perform the operator Identification.

At step 508, the operator may perform an intoxication test using one or more intoxication examination devices. The one or more intoxication examination devices may be used to estimate the intoxication level of the operator. In some embodiments, the operator may have to respond to a plurality of questions provided in an examination questionnaire, at step 510. Thereafter, at step 512, a condition of operation permissibility may be checked. In other words, permissibility of operating the asset for the operator may be determined. The ML model may be used to check the permissibility. In some embodiments, the ML model may be an ensemble model. Further, examples of the ML model may include, but are not limited to a supervised learning ML model, an unsupervised learning ML model, a regression type ML model, a classification type ML model, a random forest ML model, a Neural Network (NN) model or the like.

In one embodiment, the permissibility may be checked based on an intoxication score determined by the ML model which may be determined based on the video recording, the user details, a user profile, and the intoxication test. For example, when the intoxication score of the operator is above a predefined threshold score required for operating the asset, the asset operation is permissible. In some other embodiments, the permissibility may be checked based on a plurality of responses corresponding to an examination questionnaire received from the operator. For example, when the operator correctly answers more than a predefined threshold number of questions in the questionnaire, the asset operation is permissible.

At step 514, the operator may assign the asset to self when the permissibility condition is true, or the asset operation is permissible. At step 516, the server generates a signal of asset authorization. The signal may be transmitted to the assigned asset. At step 518, the asset may verify the operation authorization and upon successful authorization allows the operator to access the asset.

Further, in case the asset operation is not permissible, failed authorization attempts by the operator may be stored in a historical dataset (examination repository) associated with the operator, at step 520. Further, at step 520, upon successful verification of the operation authorization corresponding data may be saved to the examination repository.

At step 522, a manager/administrator may verify the intoxication examination performed by the operator. At step 524, manager/administrator may review the access of operator to the asset. The manager/administrator may use data save in the examination repository. The examination repository may include, but not limited to, the real-time video data, intoxication examination results, operator's information, video recordings, intermediate results generated while performing various steps, and a number of failed authorization attempts by the operator in a historical dataset associated with the operator.

Referring now to FIG. 6, a method of operating an asset through a video call-based intoxication examination is depicted via a flowchart 600, in accordance with some embodiments of the present disclosure. FIG. 6 is explained in conjunction with FIGS. 1-5.

At step 602, an operator may sign-in using login credentials. In case, sign-in details or credentials provided by the operator are correct or successfully validated by a server (for example the centralized server 202, 302) then the operator may connect with the system for further processing. By way of an example, in FIG. 6 a video-call examination with the manager/administrator is explained, where the operator may video call the manager/administrator through a video camera.

At step 604, the operator may turn on the video camera to start a video call with the manager/administrator. However, in the self-examination video camera may be used only to record a video of evidence. In the current example, the video camera may be used for both the purpose (i.e., for initiating the video call and recording the video of evidence). Further, a manager/administrator may accept or reject the video call. The manger/administrator may join the call, at step 606.

At step 608, an operator verification may be performed through a biometric identification test and/or an Identity Document (ID) verification. The biometric identification test may include, but is not limited to facial recognition, fingerprint matching, voice recognition, retina scanning, and the like. In some embodiments, the operator may be allowed to use a valid ID proof issued by an employer (such as, an employee ID card), and a valid ID proof issued by a government agency (such as a driving license). In some embodiments, an Optical Character Recognition (OCR) technique, a barcode, and a QR Code may be used for ID verification.

At step 610, an intoxication detection test may be performed by the operator through an intoxication detection device (same as the intoxication detection device 212b). The intoxication detection test may be performed to measure presence of alcohol or drug. The intoxication detection device may include a breath-based device (such as a breathalyzer), a touch-based device (such as an alcometer), or a blood-based or saliva-based test-kit.

At step 612, the operator may response to a plurality of questions provided in an examination questionnaire. The examination questionnaire may include questions and puzzles to review the physical and mental fitment of the operator required to securely perform the operation of the asset. At step 614, the manager/administrator may verify the intoxication examination based on the intoxication test and the responses to the examination questionnaire. Further, the manager/administrator may approve/reject the intoxication examination.

At step 616, it may be checked if the operation is permissible. In other words, permissibility of operating the asset for the operator may be determined. A Machine Learning (ML) may be used to check the permissibility. In some embodiments, the ML model may be an ensemble model. Further, examples of the ML model may include, but are not limited to, a supervised learning ML model, an unsupervised learning ML model, a regression type ML model, a classification type ML model, a random forest ML model, a Neural Network (NN) model or the like.

At step 618, the manager may assign the asset to the operator if the operation is permissible. At step 620, an operation authorization may be generated by the server. Further, a signal corresponding to the operation authorization may be sent to the asset. The asset may further verify the operation authorization and based on verification allow the access to the operator, at step 622.

Further, at step 624, data may be stored in an examination repository (such as, the examination repository 210a). The examination repository may be used to store data including a recording of the video-call intoxication examination, measurements from the intoxication detection device, answers to the examination questionnaire, decision taken by the system based on business rules, and approval information by the manager. At step 626, the manager/administrator may review the access of the operator to the asset.

The video of evidence may be recorded using the video camera by the operator. This video of evidence may be used to check intoxication level of the operator.

At step 706, an operator verification may be performed through a biometric identification test and/or an Identity Document (ID) verification. The biometric identification test may include, but is not limited to facial recognition, fingerprint matching, voice recognition, retina scanning, and the like. In some embodiments, the operator may be allowed to use a valid ID proof issued by an employer (such as, an employee ID card), and a valid ID proof issued by a government agency (such as a driving license). In some embodiments, an Optical Character Recognition (OCR) technique, a barcode, and a QR Code may be used for ID verification.

At step 708, an intoxication detection test may be performed by the operator through an intoxication detection device (same as the intoxication detection device 212b). The intoxication detection test may be performed to measure presence of alcohol or drug. The intoxication detection device may include a breath-based device (such as a breathalyzer), a touch-based device (such as an alcometer), or a blood-based or saliva-based test-kit.

At step 710, the operator may response to a plurality of questions provided in an examination questionnaire. The examination questionnaire may include questions and puzzles to review the physical and mental fitment of the operator required to securely perform the operation of the asset. At step 712, the manager/administrator may verify the intoxication examination based on the intoxication test and the responses to the examination questionnaire. Further, the manager/administrator may approve/reject the intoxication examination.

At step 714, it may be checked if the operation is permissible. In other words, permissibility of operating the asset for the operator may be determined. A Machine Learning (ML) model may be used to check the permissibility. In some embodiments, the ML model may be an ensemble model. Further, examples of the ML model may include, but are not limited to, a supervised learning ML model, an unsupervised learning ML model, a regression type ML model, a classification type ML model, a random forest ML model, a Neural Network (NN) model or the like.

Further, the submission screen 1704 may include a submit button 1704d to submit all the details of the intoxication examination.

The acknowledgement screen 1706 may appear after pressing the submit button 1704d. The acknowledgement screen 1706 may represent a message of acknowledgement “Thank You! Your test is submitted”. Further the acknowledgement screen 1706 may also have an option of going back to home screen 1706a.

The disclosed methods and systems may be implemented on a conventional or a general-purpose computer system, such as a personal computer (PC) or server computer. Referring now to FIG. 18, an exemplary computing system 1800 that may be employed to implement processing functionality for various embodiments (e.g., as a SIMD device, client device, server device, one or more processors, or the like) is illustrated. Those skilled in the relevant art will also recognize how to implement the invention using other computer systems or architectures. The computing system 1800 may represent, for example, a user device such as a desktop, a laptop, a mobile phone, personal entertainment device, DVR, and so on, or any other type of special or general-purpose computing device as may be desirable or appropriate for a given application or environment. The computing system 1800 may include one or more processors, such as a processor 1802 that may be implemented using a general or special purpose processing engine such as, for example, a microprocessor, microcontroller or other control logic. In this example, the processor 802 is connected to a bus 1802 or other communication medium. In some embodiments, the processor 1802 may be an AI processor, which may be implemented as a Tensor Processing Unit (TPU), or a graphical processor unit, or a custom programmable solution Field-Programmable Gate Array (FPGA).

The computing system 1800 may also include a memory 1806 (main memory), for example, Random Access Memory (RAM) or other dynamic memory, for storing information and instructions to be executed by the processor 1802. The memory 1806 also may be used for storing temporary variables or other intermediate information during execution of instructions to be executed by the processor 1802. The computing system 1800 may likewise include a read only memory (“ROM”) or other static storage device coupled to bus 1804 for storing static information and instructions for the processor 1802.

The computing system 1800 may also include a storage device 1808, which may include, for example, a media drives 1810 and a removable storage interface. The media drive 1810 may include a drive or other mechanism to support fixed or removable storage media, such as a hard disk drive, a floppy disk drive, a magnetic tape drive, an SD card port, a USB port, a micro USB, an optical disk drive, a CD or DVD drive (R or RW), or other removable or fixed media drive. A storage media 1812 may include, for example, a hard disk, magnetic tape, flash drive, or other fixed or removable medium that is read by and written to by the media drive 1810. As these examples illustrate, the storage media 1812 may include a computer-readable storage medium having stored there in particular computer software or data.

In alternative embodiments, the storage devices 1808 may include other similar instrumentalities for allowing computer programs or other instructions or data to be loaded into the computing system 1800. Such instrumentalities may include, for example, a removable storage unit 1814 and a storage unit interface 1816, such as a program cartridge and cartridge interface, a removable memory (for example, a flash memory or other removable memory module) and memory slot, and other removable storage units and interfaces that allow software and data to be transferred from the removable storage unit 1814 to the computing system 1800.

The computing system 1800 may also include a communications interface 1818. The communications interface 1818 may be used to allow software and data to be transferred between the computing system 1800 and external devices. Examples of the communications interface 1818 may include a network interface (such as an Ethernet or other NIC card), a communications port (such as for example, a USB port, a micro USB port), Near field Communication (NFC), etc. Software and data transferred via the communications interface 1818 are in the form of signals which may be electronic, electromagnetic, optical, or other signals capable of being received by the communications interface 1818. These signals are provided to the communications interface 1818 via a channel 1820. The channel 1820 may carry signals and may be implemented using a wireless medium, wire or cable, fiber optics, or other communications medium. Some examples of the channel 1820 may include a phone line, a cellular phone link, an RF link, a Bluetooth link, a network interface, a local or wide area network, and other communications channels.

The computing system 1800 may further include Input/Output (I/O) devices 1822. Examples may include, but are not limited to a display, keypad, microphone, audio speakers, vibrating motor, LED lights, etc. The I/O devices 1822 may receive input from a user and also display an output of the computation performed by the processor 1802. In this document, the terms “computer program product” and “computer-readable medium” may be used generally to refer to media such as, for example, the memory 1812, the storage devices 1808, the removable storage unit 1814, or signal(s) on the channel 1820. These and other forms of computer-readable media may be involved in providing one or more sequences of one or more instructions to the processor 1802 for execution. Such instructions, generally referred to as “computer program code” (which may be grouped in the form of computer programs or other groupings), when executed, enable the computing system 1800 to perform features or functions of embodiments of the present invention.

In an embodiment where the elements are implemented using software, the software may be stored in a computer-readable medium and loaded into the computing system 1800 using, for example, the removable storage unit 1814, the media drive 1810 or the communications interface 1818. The control logic (in this example, software instructions or computer program code), when executed by the processor 1802, causes the processor 1802 to perform the functions of the invention as described herein.

Thus, the present disclosure may overcome drawbacks of traditional systems discussed before. The present disclosure may enable the enterprises to implement a system for proactive screening of employees for alcohol and drug abuse (ADA) before they are allowed to perform a job. Further, the business establishment across the industry segments may benefit with implementation of Driving Under the Influence (DUI) prevention and Drug-Free Workplace (DFW) programs. The industry segment may include transport and logistics companies, railways, airlines, air traffic operations, defense establishments, police and security forces, nuclear operations, shipyard industry, maritime industry, oil refineries, mining industry, construction industry, warehouse, manufacturing industry, and the like. The present disclosure provides an intoxication examination method that may alternatively suites to different workplace scenarios. For example, the self-examination may be suitable for scenarios where an operator is required to work from remote locations, but a manager may be unavailable physically or virtually. In such scenarios, the operator may be allowed to perform the self-examination for intoxications and fitness levels, and then the operator needs to follow decisions of the system based on permissibility of the operation. By way of another example, the video-call examination method may be suitable for the scenarios where the operator is required to work from remote locations often and may connect with a manager virtually over a video call. In such scenarios, the operator may be allowed to have a video call with the manager while intoxications and fitness examination is carried out. Further, the in-person examination method may be suitable for the scenarios where the operator is required to visit a location and meet in-person with the manager. In such scenarios, the operator may be required to take intoxications and fitness examination directly and physical supervision of the manager.

Further, the disclosure may enable the enterprises to use a wide range of choices from various options for biometric identification and ID verifications. The biometric identification may include a facial recognition, a fingerprint matching, a voice recognition, a retina scan, and the like. The ID verification may include an Optical Character Recognition (OCR) technique, a Barcode technique, and a QR Code technique. Further, the disclosure enables assigning an asset to the operator after qualifying intoxication examination. The operation authorization and the asset access control may enable the asset to implement access control based on conditions of operations for the operator.

It will be appreciated that, for clarity purposes, the above description has described embodiments of the invention with reference to different functional units and processors. However, it will be apparent that any suitable distribution of functionality between different functional units, processors or domains may be used without detracting from the invention. For example, functionality illustrated to be performed by separate processors or controllers may be performed by the same processor or controller. Hence, references to specific functional units are only to be seen as references to suitable means for providing the described functionality, rather than indicative of a strict logical or physical structure or organization.

Although the present invention has been described in connection with some embodiments, it is not intended to be limited to the specific form set forth herein. Rather, the scope of the present invention is limited only by the claims. Additionally, although a feature may appear to be described in connection with particular embodiments, one skilled in the art would recognize that various features of the described embodiments may be combined in accordance with the invention.

Furthermore, although individually listed, a plurality of means, elements or process steps may be implemented by, for example, a single unit or processor. Additionally, although individual features may be included in different claims, these may possibly be advantageously combined, and the inclusion in different claims does not imply that a combination of features is not feasible and/or advantageous. Also, the inclusion of a feature in one category of claims does not imply a limitation to this category, but rather the feature may be equally applicable to other claim categories, as appropriate.
