This paper provides an overview on the importance of ethical obligations to help ensure end-product safety and its certifications effectively address and satisfy component level application considerations. These are known as “Conditions of Acceptability” for most North American certification reports and “Application Considerations” for most European Union certification authority reports.

There has to be a better way of specifying EMI filter performance – one that shows a filter’s effectiveness in real-life situations. It turns out there is a better alternative test method that fulfills this need. This method is the insertion loss test method for non-50Ω systems, located in Annex C of the second edition of EN 55017 (a.k.a. CISPR 17).

The growing application of lithium-ion batteries brings with it an increased risk of unanticipated energy releases and thermal runaway. Quantifying battery energy release characteristics during product design can help mitigate those risks.

In Part 1 of this two-part article, we’ll discuss the development of “grounding networks” and the shift to meshed structures to reduce damage from overvoltages. Part 2 will appear in our November 2020 issue.

This article presents methods for building reduced-order models (ROMs) based on proper orthogonal decomposition (POD) for modeling transient heat transfer in partially-perfuse tissue in prolonged contact with a heat-generating wearable device.
