    适用范围:The scope of this standard is to establish a normativedefinition of communication between personal telehealth peak flowmonitoring devices (agents) and managers (e.g., cell phones,personal computers, personal health appliances, and set top boxes)in a manner that enables plug-and-play interoperability. Itleverages work done in other ISO/IEEE 11073 standards includingexisting terminology, information profiles, application profilestandards, and transport standards. It specifies the use ofspecific term codes, formats, and behaviors in telehealthenvironments restricting optionality in base frameworks in favor ofinteroperability. This standard defines a common core offunctionality of a peak-flow monitoring device. The use case isrestricted to personal respiratory monitoring and therefore doesnot include hospital-based spirometry. Continuous and high-acuitymonitoring (e.g., for emergency response) are outside the scope ofthe use case. In the context of personal health devices, a peak flow meter isa device is used to measure the respiratory function of thosemanaging respiratory conditions such as asthma and chronicobstructive pulmonary disease. The ability to identify decliningrespiratory status prior to the need for acute interventionimproves the quality of life for the individual while reducing theoverall costs of care. Respiratory status data are collected by apersonal respiratory monitoring device and forwarded to a centraldata repository for review and action by a health care provider.The data are episodic in nature and are forwarded at designatedintervals or when the person is symptomatic. This standard provides the data modeling and its transport shimlayer according to IEEE Std 11073- 20601TM-2008 and doesnot specify the measurement method. Purpose This standard addresses a need for an openly defined,independent standard for controlling information exchange to andfrom personal health devices (agents) and managers (e.g. cellphones, personal computers, personal health appliances, set topboxes). Interoperability is key to growing the potential market forthese devices and enabling people to be better informedparticipants in the management of their health

    适用范围:Foreword  (This Foreword is not a part of ANSI/IEEE Std 125-1988, IEEE Recommended Practice for Preparation of Equipment Specifications for Speed-Governing of Hydraulic Turbines Intended to Drive Electric Generators). The 1977 revision of IEEE Std 125 was prepared by a joint IEEE-ASME Working Group formed in December of 1971. The personnel of this Working Group were appointed by J. T. Madill, Chairman, Hydroelectric Power Subcommittee, IEEE, at the direction of W. S. Morgan, Chairman, Power Generation Committee, IEEE, in cooperation with ASME. The 1988 revision of the standard was initiated in 1982 by R. D. Handel, Chairman, Hydroelectric Power Subcommittee, Power Generation Committee, IEEE, in cooperation with W. O. Hays, Director, Power Test Codes, ASME. The Working Group that formulated the 1988 standard included representatives from IEEE and ASME. The standard includes the latest practices on the North American continent and, insofar as possible, has been made consistent with ANSI/ASME Std PTC29-1980 (R1985), Speed-Governing Systems for Hydraulic Turbine-Generator Units, and IEC Std 308-1970, International Code for Testing of Speed Governing Systems for Hydraulic Turbines. As the title implies, this document is a recommended practice and not a complete specification. It has been developed to be used by prospective purchasers of hydraulic turbine governors in preparing detailed procurement speci˝cations for such equipment. In certain cases, performance criteria such as temperature range or fluid velocity, representative of North American practice, have been included; the specification writer may wish to verify their applicability to his job. Section 2. defines terms, functions, and characteristics as commonly used in North America. Wherever possible, the 1988 revision utilizes symbols adopted by IEC Std 308-1970, International Code for Testing of Speed Governing Systems for Hydraulic Turbines. A number of definitions covering detailed aspects of control system frequency response have been deleted from the 1988 revision, as these definitions are well covered in ANSI Std MC85.1M-1981, Terminology for Automatic Control. Section 3. describes specific components that may be included in a governor system. The purchaser should specify only those components he feels are required to interface with his equipment. The practice should not be incorporated verbatim, as it contains certain explanatory comments directed to the specification writer. When convenient, these explanatory comments have been enclosed in parentheses. The 1988 revision addresses equipment aspects that have gained prominence since release of the 1977 standard, in particular those related to electric-hydraulic governors. Included are new guide specifications on power supply design (reliability and redundancy considerations), transient immunity (emi and rfi), electronic components, test facilities, and accessories such as generation control circuits. Also, a number of the equipment specifications have been revised to reßect the latest industry practices and to provide consistency in terminology. In particular, clarification has been provided on the sizing of the hydraulic pressure tank for adjustable blade and impulse turbines. In addition to the special considerations affecting electric governors outlined above, guide specifications have been added for items common to both non-electric and electric governors. These include auxiliary components for pump turbines, cabinet construction, ac and dc control power, rotor creep detector, fire protection system, emergency stop controls, and hydraulic pressure supply system accessories. Section 4. defines the performance characteristics of a good governor system and adjustments and tests to obtain and confirm the desired performance. Prior to or concurrent with the writing of the specification, the purchaser should make studies to determine the required performance and the adjustments associated with that performance. The purchaser should also determine what tests are necessary to confirm that the desired performance has been obtained. Specifications related to the adequacy of the damping system have been clarified in the 1988 revision. A paragraph has also been included on the requirements for stability studies to be conducted by the governor manufacturer. Section 5. is intended to make suf˝cient information available to the purchaser so that he can assure himself that the governor equipment will interface properly with other equipment. It is also intended to provide adequate information for maintenance purposes. Section 6. deals with the criteria for acceptance tests. Section 7. lists the data that will be furnished by the purchaser. Tests for evaluating the speed control performance, included in Appendix I, have been clarified in the 1988 revision to reflect the current practices of users. At the time of approval of the 1977 standard the personnel of the Joint IEEE/ASME Working Group on Updating IEEE Specification No 125 Covering Speed-Governing of Hydraulic Turbines Intended to Drive Electric Generators was as follows: L. M. Hovey, (Chairman) E. A. Cooper L. Eilts J. Roddy Huff C. Humphreys G. Dugan Johnson D. G. McFarlane G. R. Meloy P. L. Moran R. M. Rockwell F. R. Schleif D. A.

    适用范围:This document provides guidance for an objective evaluation of lithium-based energy storage technologies by a potential user for any stationary application. This document is to be used in conjunction with IEEE Std 1679™-2010, IEEE Recommended Practice for the Characterization and Evaluation of Emerging Energy Storage Technologies in Stationary Applications.1 For the purposes of this document, lithium-based batteries include those secondary (rechargeable) electrochemistries with lithium ions as the active species exchanged between the electrodes during charging and discharging. Examples of secondary lithium-based batteries are lithium-ion, lithium-ion polymer, lithium-metal polymer, and lithium-sulfur batteries. Primary (non-rechargeable) lithium batteries are beyond the scope of this document. While this document does not cover lithium-based batteries used in mobile applications, the information provided is applicable to electric vehicle or similar batteries that are repurposed for use in stationary applications. This document also applies to batteries that are stationary when in operation but are intended to be relocated, for example, containerized or trailer-mounted systems. The outline of IEEE Std 1679-2010 is followed in this document, with tutorial information specific to lithium-based batteries provided as appropriate. Examples of tutorial information include technology descriptions, operating parameters, failure modes, safety information, battery architecture, and qualification and application considerations. This document does not cover sizing, installation, maintenance, and testing techniques, except insofar as they may influence the evaluation of a lithium-based battery for its intended application. Purpose Lithium-based batteries have been used in various, non-stationary applications for many years. They are now beginning to be used in stationary applications and, as such, there is a need to provide appropriate information on safety and operating conditions related to these applications. End-users would benefit from having a guide to assist in evaluation of this technology for stationary applications. Used with IEEE Std 1679-2010, this guide describes a format for the characterization of lithium-based battery technologies in terms of performance, service life, and safety attributes. This format will provide a framework for developers and manufacturers to describe their products. The resulting information will assist users, integrators, and servicing organizations in evaluating the possible use of these batteries in stationary applications and to provide objective criteria for comparative evaluation.

    有效 IEEE 1855-2016 Fuzzy Markup Language
    语言:英语
    适用范围:This standard defines an eXtensible Markup Language (XML)-based language, named Fuzzy Markup Language (FML), aimed at providing a unified and well-defined representation of Fuzzy Logic Systems (FLSs). This standard includes an extendable schema that natively defines the basic components of an FLS and enables the modeling of different categories of fuzzy inference engines, including Mamdani [B16], Tsukamoto [B21], Takagi-Sugeno-Kang (TSK) [B20], and AnYa [B5]. Purpose The purpose of this standard is to allow the creation of interoperable FLSs. This standard uses the W3C XML Schema definition (XSD) language as the encoder, which allows for interoperability and the exchange of XML-based FLS instances between various systems. Different from other approaches used to describe fuzzy systems such as Fuzzy Control Language (FCL), FML allows fuzzy designers to simply code their ideas on heterogeneous hardware without need for a deep understanding of details related to the different platforms. This approach enables fuzzy systems designers to achieve design transparency. It means that, by using FML, it is possible to implement the same FLS on different hardware architectures with minimal effort and without additional design and implementation steps. In short, FML makes it possible to model an FLS in a human-readable and hardware-independent way.
