Data interchange and standard software services for test and diagnostic environments are defined by Artificial Intelligence Exchange and Service Tie to All Test Environments (AIESTATE). The purpose of AI-ESTATE is to standardize interfaces for functional elements of an intelligent diagnostic reasoner and representations of diagnostic knowledge and data for use by such diagnostic reasoners. Formal information models are defined to form the basis for a format to facilitate exchange of persistent… read more diagnostic information between two reasoners and also to provide a formal typing system for diagnostic services. The services to control a diagnostic reasoned are defined by this standard. read less

This Guide addresses the application of transformers in the presence of oscillatory switching transients. These oscillatory transients are typically produced by the interaction of the switching device, transformer, load, and system. This Guide defines operating conditions that may produce switching voltages damaging to the transformer insulation system. It discusses the electrical characteristics of the system source, switching device, transformer, and load and the nature of their transient… read more interaction. It outlines several mitigation methods. Two examples are included. This Guide recognizes that many devices and/or system operations can produce oscillatory transient waveforms. The focus of this Guide is on the interaction between a transformer, the system, and a switching device as a result of several reports of transformer internal winding failures. This Guide focuses only on mechanical switching devices and does not cover semiconductor switching devices. Transformers that are inductively loaded (reactors, or stalled or accelerating motors) are not covered by this document but are addressed by several other referenced publications. read less

This standard specifies the application service layer and profile for Payment and Identity authentication, and Payment Data transfer for Dedicated Short Range Communication (DSRC) based applications using IEEE Std 802.11(TM) and IEEE 1609 protocols in Wireless Access in Vehicular Environments. This standard defines a basic level of technical interoperability for electronic payment equipment, i.e., onboard unit (OBU) and roadside unit (RSU). It does not provide a full solution for interoperability, and it does not define other parts of the electronic payment-system, other services, other technologies, and non-technical elements of interoperability. This standard is not intended to define technology and processes to activate and store data into the OBU (personalization).
