DETAILED DESCRIPTION
Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, but mean “one or more but not all embodiments” unless expressly specified otherwise. The terms “including,” “comprising,” “having,” and variations thereof mean “including but not limited to” unless expressly specified otherwise. An enumerated listing of items does not imply that any or all of the items are mutually exclusive and/or mutually inclusive, unless expressly specified otherwise. The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise.
Furthermore, the described features, advantages, and characteristics of the embodiments may be combined in any suitable manner. One skilled in the relevant art will recognize that the embodiments may be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments.
These features and advantages of the embodiments will become more fully apparent from the following description and appended claims, or may be learned by the practice of embodiments as set forth hereinafter. As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method, and/or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module,” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having program code embodied thereon.
Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
Modules may also be implemented in software for execution by various types of processors. An identified module of program code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of program code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network. Where a module or portions of a module are implemented in software, the program code may be stored and/or propagated on in one or more computer readable medium(s).
The computer readable medium may be a tangible and/or non-transitory computer readable storage medium storing the program code. The computer readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, holographic, micromechanical, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing.
More specific examples of the computer readable storage medium may include but are not limited to a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a portable compact disc read-only memory (CD-ROM), a digital versatile disc (DVD), an optical storage device, a magnetic storage device, a holographic storage medium, a micromechanical storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, and/or store program code for use by and/or in connection with an instruction execution system, apparatus, or device.
Program code for carrying out operations for aspects of the present invention may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Small talk, C++, or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the operator's computer, partly on the operator's computer, as a stand-alone software package, partly on the operator's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the operator's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).
The computer program product may be shared, simultaneously serving multiple customers in a flexible, automated fashion. The computer program product may be standardized, requiring little customization and scalable, providing capacity on demand in a pay-as-you-go model.
The computer program product may be stored on a shared file system accessible from one or more servers. The computer program product may be executed via transactions that contain data and server processing requests that use Central Processor Unit (CPU) units on the accessed server. CPU may be units of time such as minutes, seconds, hours on the central processor of the server. Additionally the accessed server may make requests of other servers that require CPU units. CPU units are an example that represents but one measurement of use. Other measurements of use include but are not limited to network bandwidth, memory usage, storage usage, packet transfers, complete transactions etc.
When multiple customers use the same computer program product via shared execution, transactions are differentiated by the parameters included in the transactions that identify the unique customer and the type of service for that customer. All of the CPU units and other measurements of use that are used for the services for each customer are recorded. When the number of transactions to any one server reaches a number that begins to affect the performance of that server, other servers are accessed to increase the capacity and to share the workload. Likewise when other measurements of use such as network bandwidth, memory usage, storage usage, etc. approach a capacity so as to affect performance, additional network bandwidth, memory usage, storage etc. are added to share the workload.
The measurements of use used for each service and customer are sent to a collecting server that sums the measurements of use for each customer for each service that was processed anywhere in the network of servers that provide the shared execution of the computer program product. The summed measurements of use units are periodically multiplied by unit costs and the resulting total computer program product service costs are alternatively sent to the customer and or indicated on a web site accessed by the customer which then remits payment to the service provider.
In one embodiment, the service provider requests payment directly from a customer account at a banking or financial institution. In another embodiment, if the service provider is also a customer of the customer that uses the computer program product, the payment owed to the service provider is reconciled to the payment owed by the service provider to minimize the transfer of payments.
The computer program product may be integrated into a client, server and network environment by providing for the computer program product to coexist with applications, operating systems and network operating systems software and then installing the computer program product on the clients and servers in the environment where the computer program product will function.
In one embodiment software is identified on the clients and servers including the network operating system where the computer program product will be deployed that are required by the computer program product or that work in conjunction with the computer program product. This includes the network operating system that is software that enhances a basic operating system by adding networking features.
In one embodiment, software applications and version numbers are identified and compared to the list of software applications and version numbers that have been tested to work with the computer program product. Those software applications that are missing or that do not match the correct version will be upgraded with the correct version numbers. Program instructions that pass parameters from the computer program product to the software applications will be checked to ensure the parameter lists match the parameter lists required by the computer program product. Conversely parameters passed by the software applications to the computer program product will be checked to ensure the parameters match the parameters required by the computer program product. The client and server operating systems including the network operating systems will be identified and compared to the list of operating systems, version numbers and network software that have been tested to work with the computer program product. Those operating systems, version numbers and network software that do not match the list of tested operating systems and version numbers will be upgraded on the clients and servers to the required level.
In response to determining that the software where the computer program product is to be deployed, is at the correct version level that has been tested to work with the computer program product, the integration is completed by installing the computer program product on the clients and servers.
Furthermore, the described features, structures, or characteristics of the embodiments may be combined in any suitable manner. In the following description, numerous specific details are provided, such as examples of programming, software modules, operator selections, network transactions, database queries, database structures, hardware module, hardware circuits, hardware chips, etc., to provide a thorough understanding of embodiments. One skilled in the relevant art will recognize, however, that embodiments may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of an embodiment.
Aspects of the embodiments are described below with reference to schematic flowchart diagrams and/or schematic block diagrams of methods, apparatuses, systems, and computer program products according to embodiments of the invention. It will be understood that each block of the schematic flowchart diagrams and/or schematic block diagrams, and combinations of blocks in the schematic flowchart diagrams and/or schematic block diagrams, can be implemented by program code. The program code may be provided to a processor of a general purpose computer, special purpose computer, sequencer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the schematic flowchart diagrams and/or schematic block diagrams block or blocks.
The program code may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the schematic flowchart diagrams and/or schematic block diagrams block or blocks.
The program code may also be loaded onto a computer, other programmable data processing apparatus, or other devices to cause a series of operational steps to be performed on the computer, other programmable apparatus or other devices to produce a computer implemented process such that the program code which executed on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.
The schematic flowchart diagrams and/or schematic block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of apparatuses, systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the schematic flowchart diagrams and/or schematic block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions of the program code for implementing the specified logical function(s).
It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. Other steps and methods may be conceived that are equivalent in function, logic, or effect to one or more blocks, or portions thereof, of the illustrated Figures.
Although various arrow types and line types may be employed in the flowchart and/or block diagrams, they are understood not to limit the scope of the corresponding embodiments. Indeed, some arrows or other connectors may be used to indicate only the logical flow of the depicted embodiment. For instance, an arrow may indicate a waiting or monitoring period of unspecified duration between enumerated steps of the depicted embodiment. It will also be noted that each block of the block diagrams and/or flowchart diagrams, and combinations of blocks in the block diagrams and/or flowchart diagrams, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and program code.
The description of elements in each figure may refer to elements of proceeding figures. Like numbers refer to like elements in all figures, including alternate embodiments of like elements.
Embodiments Elements
FIG. 1 is a schematic block diagram illustrating one embodiment of a system 100 for providing procedures. The system 100 provides a procedure for equipment 160. The system 100 includes a server 120, a procedure database 125, a operator database 140, an audit database 165, a tutorial database 170, a workstation 135, a network 115, a mobile device 105, a plurality of equipment 160, and an equipment reference code 205 for each equipment instance 160. For simplicity, a single equipment instance 160 and a single equipment reference code 205 are shown.
The equipment 160 may be electrical equipment, hydraulic equipment, compressed air equipment, steam equipment, mechanical tools, protective equipment, refrigeration equipment, power lines, hydraulic lines, steam lines, or combinations thereof. Alternatively, the equipment 160 may be containers of hazardous substances, containers of biological substances, containers of chemical substances, or combinations thereof.
An equipment procedure is often specified for safely operating and/or maintaining the equipment 160. The equipment procedure may specify in more detail the process steps, tools, safety equipment, and the like that must be complied with when operating and maintaining the equipment 160. The equipment 160 may also require one or more equipment permits to comply with regulations for the equipment 160.
Unfortunately, in the past the equipment procedures and/or equipment permits have not always been available when there is a need to operate and/or maintain the equipment 160. For example, when equipment procedures are centrally stored, a operator may need to anticipate and acquire the required equipment procedures before operating and/or maintaining the equipment 160.
In addition, the operator that had earlier acquired the equipment procedure may be unaware that the equipment procedure had been updated. As a result, in the past, operators have often lacked the latest equipment procedures or did not have the latest equipment permits.
The embodiments described herein provide the most current equipment procedures to the operator as will be described hereafter. In addition, the embodiments provide current equipment permits. As a result, even when working remotely, the operator is assured of having the most current equipment procedures and/or equipment permits, allowing the operator to safely operate or maintain the equipment 160.
In order to enhance safety and comply with safety regulations, the availability and proper use of an equipment procedure for the equipment 160 may be periodically audited. Such an audit may be difficult to track, manage, and report. The embodiments also record if the operator follows an equipment procedure and/or complies with an equipment permit to an audit report and synchronizes the audit report to the audit database 165 as will be described hereafter.
An operator may be uncertain as to how to apply equipment procedures. The embodiments also provide equipment tutorials associated with the equipment 160. The operator may access the equipment tutorials to learn how to properly carry out steps of the equipment procedures as will be described hereafter.
The operator may be unaware of the consequences of violating the equipment procedures or performing the equipment procedures incorrectly. In addition, the operator may be unaware of the consequences of disregarding requirements of the equipment permits. The embodiments may receive a selection of a procedure step from the operator in response to a procedure description. The embodiments may further display a step consequence depicting an operator simulation interacting with the machine simulation in response to the procedure step as will be described hereafter. As a result, the operator is given a strong visual reinforcement of the learning of the tutorial, making the lessons of the tutorial more memorable and effective.
The equipment reference code 205 is associated with the equipment 160. The equipment reference code 205 may be affixed to the equipment 160. Alternatively, the equipment reference code may be mounted near the equipment 160. In one embodiment, the equipment reference code 205 is printed on an adhesive label that is affixed to the equipment 160. The equipment reference code 205 may be encoded as a Quick Reference (QR) code. In addition, the equipment reference code 205 may also be displayed in a human readable form.
In an alternate embodiment, the equipment reference code 205 is encoded as a barcode. The equipment reference code 205 may also be encoded as an identification code broadcast via a Radio Frequency Identifier (RFID).
The equipment reference code 205 refers to equipment procedures stored in the procedure database 125. In addition, the equipment reference code 205 may refer to equipment permits for the equipment 160. In one embodiment, the equipment reference code 205 is used as an index to the equipment procedures and/or equipment permits. The equipment procedures and equipment permits may be created, edited, updated, and/or deleted from the workstation 135.
The server 120 may communicate the equipment procedures and/or equipment permits through the network 115 to the mobile device 105. The network 115 may be the Internet, a mobile telephone network, a wide area network, a local area network, a wireless network, or combinations thereof. The server 120 may be a remote server 120.
The server 120 may synchronize all the equipment procedures and/or equipment permits in the procedure database 125 to the mobile device 105 so that the mobile device 105 stores a copy of all the equipment procedures and/or equipment permits in the procedure database 125. Thus all the equipment procedures and/or equipment permits may be available on the mobile device 105. In addition, the server 120 may synchronize equipment tutorials from the tutorial database 170 to the mobile device 105.
The mobile device 105 may further display the step simulation showing the consequences of a selected procedure step. As a result, the lessons of the equipment tutorials are made more meaningful and memorable.
The equipment procedures may be grouped by site. In one embodiment, the server 120 maintains a site list of all the equipment 160 at a specified site. The site list may include an equipment reference code 205 for each equipment instance 160 at the specified site. Alternatively, the site list may include a procedure identifier for each equipment instance 160 at the specified site. The server 120 may synchronize only the equipment procedures and/or equipment permits of a site list to the mobile device 105 in response to receiving an equipment reference code 205 and/or procedure identifier for one of the equipment instances 160 on the site list. In one embodiment, the equipment procedures and/or equipment permits are organized as a database, a data structure, or combinations thereof on the mobile device 105.
The mobile device 205 may be a tablet computer, a mobile phone, a notebook computer, a personal digital assistant, or the like. The mobile deice 105 may receive 145 the equipment reference code 205. In one embodiment, the mobile device 105 optically scans a QR code encoding the equipment reference code 205. Alternatively, the mobile device 105 may optically scan a barcode encoding the equipment reference code 205. In a certain embodiment, the mobile device 105 wirelessly queries an RFID equipment reference code 205 and receives the equipment reference code 205 encoded in a wireless response from the RFID.
The mobile device 105 may use the equipment reference code 205 as an index to retrieve the equipment procedures and/or equipment permits associated with the equipment reference code 205 from the mobile device 105. The mobile device 105 may display the equipment permits and any information associated with the equipment permits. The mobile device 105 may also display the equipment procedure, allowing the operator to perform the equipment procedure on the equipment 160.
If the equipment procedures and/or equipment permits associated with the equipment reference code 205 are not stored on the mobile device 105, the mobile device 105 may use the equipment reference code 205 to request equipment procedures and/or equipment permits from the server 120 through the network 115. The server 120 may synchronize the equipment procedures and/or equipment permits from the procedure database 125 through the network 115 to the mobile device 105 so that the equipment procedures and/or equipment permits may be displayed by the mobile device 105.
By synchronizing the equipment procedures and/or equipment permits to the mobile device 105, a operator may reference the correct equipment permit for the equipment 160 even if a physical copy of the equipment permit is not available locally. In addition, the operator may access the correct equipment procedure for the equipment 160 on the mobile device 105 even if a paper document with the equipment procedure has been removed from the equipment 160 or if an incorrect equipment procedure is placed with the equipment 160.
