A new standard applicable to the testing and labeling of all lithium-ion batteries imported...

The risks of product liability sometime affect technological developments in hardware and software used to make products. They can stifle innovation and make some advancements seem too risky. How does the law view these products and what can be done to evaluate and reduce these risks.

In this article, the author will identify two major types of single-conductor structure resonances and describe some case studies for both. He will then describe how design projects can quickly and easily be ‘de-risked’ from the possibilities of suffering either type of resonance by the use of low-cost field and circuit simulators and/or low-cost bench testing on physical ‘mock-ups’.

Let's talk about flexible absorbing materials used for radio frequency (RF) noise suppression and EMC shielding in electronic products such as cell phones, MP3 players, and rugged handheld devices.

This article discusses CMOS inverter switching and shows the impact of a decoupling capacitor on the power rail signal integrity and radiated emissions.

Controlled environment testing of static control flooring in combination with multiple forms of ESD footwear during the qualification phase can reveal problems and is a mandatory step to avoid installing non-compliant flooring/footwear systems.

This article provides insight into how shielding is used in product development, in particular the effectiveness of shielding when it is applied at the PCB level. 

This article examines the different parts of capacitive touch design and provides a checklist of what to look for when designing a product.

The authors predict the internal electromagnetic field of a populated enclosure by using the diffusion model, and compare them with the fields obtained by the power balance method, a full-wave electromagnetic solver and measurements, to demonstrate its efficacy.

Scientists from a multi-institute team have successfully developed the most detailed image of lithium-ion battery electrodes yet.
