The audio market for wireless Bluetooth headsets is growing rapidly. People have gotten used to wireless audio systems, and the mobile phone industry is pushing towards a world without audio connectors and cables. Most of the average users who think about Bluetooth audio picture clumsy over-ear headsets with very little...

As factory automation systems become more intelligent they will move data acquisition, storage and processing out to the edge of the network, enabling real-time machine controls and management. Factories will be smarter and more connected. These “edge nodes” will predict, then prevent failures before they occur...

Connectors are often seen as the weakest link between sub-systems, and sometimes this is rightly so. This can be as a result of underspecifying the connector system or not appreciating the difference between the various rating schemes. As a result engineers tend to over-specify the connectors to ensure they are reliable...

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices
using the complete system impractical.
Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently.
During HIL test, the physical system that interfaces...

Feed-forward headsets typically are more easily developed because the design engineer usually does not have to deal with stability issues. A major drawback of this topology, however, is wind noise, since the ANC microphones are directly exposed to the ambient. An alternative that overcomes this drawback is the use of a...

This paper provides an overview of controller hardware and firmware technology. Managing the interfaces to non-volatile memory such as NAND flash on one side and to a host system on the other, as well as translating the different protocols used on both sides, is a basic function of all controllers. Additionally, flash...
