`Methods and systems are provided for communicating
`between network devices. A data dictionary may be derived
`from a device data sheet. The data dictionary may include one
`or more data definitions specific to the network device and a
`global unique identifier for the network device. The data
`dictionary and data are received from the network device.
`Data definitions from the data dictionary are used to extract
`and process information from the data. The data dictionary
`may include a hierarchal classification scheme for data
`including a first level, a second level and a third level, wherein
`the first level defines a type of data, wherein the second level
`defines a type of action, and wherein the third level defines an
`object of the action.

`
`[0006] Electronic medical systems encompass devices and
`other clinical knowledge bases. Therefore,
`they must be
`capable of taking on the traits of a highly adaptive, interpre-
`tive, and complex systems continually evolving. As medical
`knowledge deepens there are changes in how medicine and
`medical practice are defined. This includes physiology cap—
`tured by devices as well as clinical analysis. It is important
`that a method for defining and communicating ruedical infor-
`mation is extensible and flexible, This is true of any other
`evolving or adapting environment.
`[0007] As a result ofthe complexity found in medical elec—
`tronic systems and other complex systems, a substantial effort
`may be required to design, implement and maintain software
`that acquires and communicates physiological and/or other
`types of similar data. Over time the effort to design, imple—
`ment and maintain this software is both cost and labor inten-
`sive. Additional substantial effort may be required when the
`software is developed to execute on a plurality of interoper-
`ating devices, with the plurality of devices operating upon
`unique and/or particular subsets of data. The software may
`then be required to operate on multiple subsets of data char-
`acterized by distinct data types and associated data defini-
`tions. Substantial effort may also be required where the data,
`including the data types and associated data definitions, may
`be subject to change and evolve over time. Substantial effort
`may also be required where the data, including the data types
`and associated data definitions differentiate from one device
`to the next due to targeted clinical use or level of user.
`[0008]
`Software reliability may be critical in a variety of
`fields, but is particularly critical to providing adequate health
`care. Therefore, substantial efforts are required where soft-
`ware operates upon data within a health care environment.
`Lack ofreliable software interoperability within a health care
`environment may interfere with providing adequate health
`care and may harm or even kill health care patients.
`[0009] Needs exist for improved commtuiications proto-
`cols for acquisition and communication of data between net-
`work elements. Needs also exist for methods for interoper—
`ability of devices and systems.

`
`[0001] The present application claims priority to U.S. Pro-
`visional Patent Application Ser. No. 60/848,993, filed Oct. 4,
`2006 and titled “Dynamic Medical Object
`Information
`Base”, which is hereby incorporath by reference in its
`entirety. The present application incorporates by reference in
`their entireties U.S. Provisional Patent Application Ser. No.
`60/667,203, filed Mar. 30, 2005, U.S. Provisional Patent
`Application Ser. No. 60/787,147, filed Mar. 28, 2006, and
`PCT Application USZOO6/Ol 1373, filed Mar. 30, 2006.
`
`FIELD OF THE INVENTION
`
`[0002] This invention relates generally to methods, appa-
`ratus and systems for the communication of information
`among a plurality of network elements, and specifically to a
`dynamic medical object information base for interoperability
`of devices and systems.
`
`BACKGROUND OF THE INVENTION
`
`[0003] Varied computing environments may exist with
`vastly different requirements for acquisition, communication
`and storage of data depending on particular requirements of
`specific situations In particular, some computing environ-
`ments may require acquisition and communication of large
`volumes and varieties of data definitions. Furthermore, the
`requirements of many computing environments may change
`and evolve over time. An illustrative example of a computing
`environment that requires the acquisition and communication
`oflarge volumes and varieties ofdata definitions with require—
`ments that change and evolve over time may be a health care
`computing environment Other examples in other fields also
`require the acquisition and communication of large volumes
`and varieties of data definitions with requirements that
`change and evolve over time.
`[0004]
`For example, a health care computing environment
`may include a variety of medical monitoring and analysis
`devices that process physiological data and communicate the
`physiological data Via a network. The physiological data may
`include subsets of physiological data depending upon the
`application. For example, subsets of physiological data may
`include heart rate, respiration rate, blood pressure, and many
`other subsets of physiological data. The medical devices may
`include one or more types of software, and the medical
`devices and software may be configured to operate upon a
`particular subset of physiological data. The particular subset
`of physiological data may be unique to a group of one or more
`medical devices. There may also be an overlap between par-
`ticular subsets of physiological data that are processed by
`each group of one or more medical devices.
`[0005] The design of each medical device, or any other
`machine performing health assessment, is dependent upon
`the particular subset or subsets of physiological data that the
`medical device or other machine processes and communi-
`cates. The design of the software residing on the medical
`devices is also dependent upon the subset or subsets ofphysi—
`ological data or clinical outcomes that the medical device
`processes and comimmicates.
`
`SUMMARY OF THE INVENTION
`
`[001 0] Embodiments ofthe present invention solve some of
`the problems and/or overcome many of the drawbacks and
`disadvantages of the prior art by providing methods, appara-
`tus and systems for interoperability of devices and commu-
`nication systems.
`[0011] Certain embodiments of the invention accomplish
`this by providing methods including initiating a communica-
`tion link with a network device, receiving standard device
`data from the network device comprising a global unique
`identifier, and requesting a self-describing data dictionary
`from the network device, wherein the self—describing data
`dictionary comprises one or more data definitions.
`[0012] Embodiments of the present invention may include
`receiving the self-describing data dictionary from the net-
`work device in response to the request by matching the global
`unique identifier with a cached version of the self—describing
`data dictionary and accessing the cached version of the self-
`describing data dictionary and/or a corresponding member of
`a self-describing data dictionary database on a storage device
`or the Internet and accessing the self-describing data dictio-
`nary. The self—describing data dictionary may be used to
`further communicate with the network device. The self-de-
`scribing data dictionary may be used to interpret data from the
`

`

`[0013] Embodiments of the present invention may include
`a computer-readable medium carrying one or more sequences
`of instructions for controlling communications between one
`or more network devices, which instructions, when executed
`by one or more processors, cause the one or more processors
`to carry out the steps of: receiving a data dictionary corre-
`sponding to a network device wherein the data dictionary is
`derived from a device data sheet, and wherein the data dic—
`tionary comprises one or more data definitions specific to the
`network device and a global unique identifier for the network
`device, receiving data from the network device, accessing the
`one or more data definitions from the data dictionary, extract—
`ing information from the data according to the data dictio-
`nary, and processing the information.
`[0014] Embodiments of the present invention may include
`applying attributes from the data dictionary to the extracted
`information. The one or more data definitions may be stan-
`dard definitions regulated by a standard setting organization
`accessed from storage in a collection of definitions.
`[0015]
`In embodiments of the present invention the device
`data sheet is may be XML compiled to source by an applica-
`tion generator. Embodiments of the present invention may
`include serializing and deserializing byte streams of informa-
`tion wherein the serialization provides a built—in protocol
`bridge between binary and XL network devices and/or seri—
`alizing and deserializing XML wherein the serialization pro-
`vides a built-in protocol bridge between binary and XML
`network devices.
`

`
`self-describing data dictionary may further include a link
`table correlating to the one or more data definitions wherein
`the self-describing data dictionary further comprises a string
`table correlating to the link table. The data may be displayed
`to a user after processing via linking the data to strings for
`display using a scale, units, a link table and an alias. One or
`more data dictionaries may be reserved standardized data
`types or may be dynamically defined. The dynamically
`defined data dictionaries may include version information.
`The communication protocol may be backward compatible
`with previous versions of the dynamically defined data dic—
`tionaries. The data may be numeric or waveform. The one or
`more data dictionaries may be binary or XML. The one or
`more data dictionaries may be compiled by an application
`generator.
`[0019] Embodiments of the present invention may include
`a method of communicating between network devices
`embedded within a tangible medium and executed by one or
`more processors including providing one or more cached data
`dictionaries with a hierarchal classification scheme for data
`comprising a first level, a second level and a third level,
`wherein the first level defines a type of data, wherein the
`second level defines a type of action, and wherein the third
`level defines an object ofthe action, sending a communication
`request to a network device, receiving a response from the
`network device comprising identification infomiation, and
`processing the response according to the one or more cached
`data dictionaries.
`
`[0020] Embodiments of the present invention may further
`include sending a request for one or more additional data
`dictionaries to the network device and receiving the one or
`more additional data dictionaries, adding infomiation from
`the one or more additional data dictionaries into the one or
`more data dictionaries, receiving data from the network
`device and processing the data via the hierarchal classifica-
`tion scheme, and/or accessing standard data definitions based
`upon the identification information ifthe network device does
`not support self—description and the hierarchal classification
`scheme.
`
`[0021] Users may generate a device data sheet that may be
`input into an application generator. Embodiments of the
`present invention may include a method stored in a tangible
`meditun and executed by one or more processors including
`accepting information on whether one or more data defini-
`tions are needed in a
