Strategies for Low-Risk Sourcing of Components in a Constrained Market

  • Magazine Article
  • TBMG-34562
Published 2019-06-01 by Tech Briefs Media Group in United States

The medical device industry often looks to independent distributors to address chronic shortages in the availability of electronic components. Direct sourcing of electronic components for the medical device industry used to be pretty simple. An OEM would order direct from the manufacturer or through authorized distributors to obtain any required components. There was usually no need to look any further.

 

Machining Titanium Aero-Frames

  • Magazine Article
  • TBMG-34543
Published 2019-06-01 by Tech Briefs Media Group in United States

The rise of titanium for aerospace applications has been well documented in recent years. Equally, the challenges associated with the efficient, productive and high-quality machining of this popular material, have also been a topic of debate and scrutiny. Of course, every machine shop wants optimized performance from its cutters when milling titanium, but this can prove less than straightforward without the right technology and know-how in place. Today, however, thanks to a breakthrough in this area, things are beginning to change.

 

Wireless Power Transfer for Light-Duty Plug-in/Electric Vehicles and Alignment Methodology

Hybrid - EV Committee
  • Ground Vehicle Standard
  • J2954_201904
  • Current
Published 2019-04-23 by SAE International in United States
The Recommended Practice SAE J2954 establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless charging of light-duty electric and plug-in electric vehicles. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels 1, 2, and 3, with some variations. A standard for wireless power transfer (WPT) based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. The specification supports home (private) charging and public wireless charging. In the near term, vehicles that are able to be charged wirelessly under Recommended Practice SAE J2954 should also be able to be charged by SAE J1772 plug-in chargers. This Recommended Practice is planned to be standardized after the 2018 timeframe after receiving vehicle data. The contents, including frequency, parameters, specifications, procedures, and other contents of this Recommended Practice, are to be re-evaluated at that time to allow for additional developments and…

The Performance and Emissions of a Conventional Natural Gas/Diesel Dual Fuel Engine at Various Operating Conditions

University of Zagreb-Darko Kozarac, Mario Sremec, Mladen Bozic, Ante Vucetic
Published 2019-04-02 by SAE International in United States
The dual fuel combustion mode, the use of bi-fueled natural gas and diesel fuel, is an attractive alternative to standard spark ignition or compression ignition combustion modes due to potential benefits of lower CO2 emissions, lower fuel costs and the use of a fuel with an alternative supply chain. Besides the potential benefits, the dual fuel combustion mode also has its challenges. There is limited data available in the literature that illustrates how the performance of a dual fuel engine changes over the entire engine map at various operating conditions; this paper presents a comprehensive set of experimental results obtained with the conventional dual fuel operation (diesel/natural gas) at ambient intake conditions to help fill this knowledge gap. In the current experiments, methane from gas cylinders is substituted for natural gas and is injected into the intake port, while standard diesel is directly injected and used as an ignition source on a single cylinder experimental engine. The presented results are obtained at optimized operating points in terms of start of injection timing, where the criterion…

Facility Focus: Battelle Memorial Institute

  • Magazine Article
  • TBMG-34159
Published 2019-04-01 by Tech Briefs Media Group in United States

Battelle Memorial Institute was founded in the early part of the 20th century as a charitable trust focused on research in metallurgy and allied industries. Founder Gordon Battelle studied metallurgy at Yale and strongly believed that science could help businesses solve their problems. In 1923, Battelle died and left $1.5 million to create Battelle Memorial Institute for the purpose of education and for making discoveries and inventions. In 1929, Battelle opened for business in Columbus, OH.

Counterfeit Electrical, Electronic, and Electromechanical (EEE) Parts; Avoidance, Detection, Mitigation, and Disposition

G-19CI Continuous Improvement
  • Aerospace Standard
  • AS5553C
  • Current
Published 2019-03-26 by SAE International in United States
This standard is for use by organizations that procure and/or integrate and/or repair EEE parts and/or assemblies containing such items, including maintenance, repair, and overhaul (MRO) organizations. The requirements of this standard are generic and intended to be applied/flowed down, as applicable, through the supply chain, to all organizations that procure EEE parts and/or assemblies, regardless of type, size, and product provided. The mitigation of counterfeit EEE parts in this standard is risk-based, and these mitigation steps will vary depending on the criticality of the application, desired performance, and reliability of the equipment/hardware. The requirements of this document are intended to be used in conjunction with a higher-level quality standard (e.g., AS/EN/JISQ9100, ISO-9001, ANSI/ASQC E4, ASME NQA-1, AS9120, AS9003, and ISO/TS 16949 or equivalent) and other quality management system documents. They are not intended to stand alone, supersede, or cancel requirements found in other quality management system documents, requirements imposed by contracting authorities, or applicable laws and regulations unless an authorized exemption/variance has been obtained. This document is not intended to make a legal determination…

  • Current
Published 2019-02-08 by SAE International in United States
This Human Systems Integration (HSI) Standard Practice identifies the Department of Defense (DoD) approach to conducting HSI programs as part of procurement activities. This Standard covers HSI processes throughout design, development, test, production, use, and disposal. Depending on contract phase and/or complexity of the program, tailoring should be applied. The scope of this standard includes prime and subcontractor HSI activities; it does not include Government HSI activities, which are covered in the DoD HSI Handbook. HSI programs should use the latest version of standards and handbooks listed below, unless a particular revision is specifically cited in the contract.
