Advancing climate resilience using designs co-created by Artificial Intelligence Systems and community guardianship

Three-phase and single-phase ac synchronous and induction electric machines in ratings 0.18 kW (1/4 hp) and larger are covered in this guide. Primary emphasis is on the use of open or nonexplosionproof or nonflameproof enclosed machines in Zone 2 and Class I, Division 2 locations as covered in the NEC(R) (NFPA 70-2020) and CE Code(R) (CSA C22.1-2021) as applicable. Surface temperature test methods and sine wave and non-sine wave applications are covered. Precautions against excessive surface temperatures and sparking are included. To help mitigate hot surface temperatures and sparking, this document provides guidance for selecting, operating, and maintaining machines in…

Services to WAVE devices and systems are provided. Layer 3 and layer 4 of the open system interconnect (OSI) model and the Internet Protocol (IP), User Datagram Protocol (UDP), and Transmission Control Protocol (TCP) elements of the Internet model are represented. Management and data services within WAVE devices are provided.

The working group JWG 28 has identified a specific need to update the IEC/IEEE 80005-1 ED2. The matter is related to the rotation of the phases for Annex C – the Cruice annex. However, the necessary modifications affect other parts of the standard, which then also needs to be aligned to keep consistency. Additionally JWG 28 has agreed that requirements for communication, such as fibre optics, should be kept outside of IEC/IEEE 80005-1, as this document should be for high voltage only.

Certificate management protocols are specified in this document to support provisioning and management of digital certificates, as specified in IEEE Std 1609.2(TM), to end entities, that is, an actor that uses digital certificates to authorize application activities.

Export data related to motor vehicle pre-defined events in usage history is collected, recorded, stored, and exported by motor vehicle event data recorders (MVEDRs). A protocol for MVEDR output data compatibility and export protocols of MVEDR data elements is defined by this standard. A motor vehicle event data recorder connector lockout apparatus (MVEDRCLA) and a near field communication (NFC) protocol is defined for safeguarding access to a vehicle's event data recorder (EDR) data by securing the vehicle output diagnostic link connector (DLC) and establishing a chain of custody link. This standard is without prejudice to requirements of national or regional…

Requirements for functions, performance, and interface and environmental conditions for vital computers used in rail safety-related systems are established in this recommended practice. Vital computer functions are developed based on the technology of computer systems, communication, and functional safety as well as security considerations. A vital computer is composed with basic functional modules such as main process, input, output, and communication. This recommended practice can be applied to vital computers for onboard and wayside equipment in rail applications. Application systems which are developed based on vital computers are not covered, but safety-related conditions for application systems are proposed. The internal…

Wireless Access in Vehicular Environments (WAVE) is specified in the IEEE 1609 family of standards, within which certain identifiers are used. The use of these identifiers is described, and identifier values that have been allocated for use by WAVE systems are indicated.

A set of uniform design, application, and test requirements for electrical and electronic control apparatus on rail vehicles is provided in this standard.
