LEDs: The Eyes and Ears of the Internet of Things

​It may seem to be a stretch to assert that LEDs play a truly important role in the future of the Internet of Things. After all, by themselves, they’re just lights. However, with sensors tucked neatly inside and a bit of intelligence added throughout, LEDs are already evolving to be our eyes and ears as the rapidly expanding IoT unfolds before us.
Hybrid Architectures Enable High Performance for Defense Systems

Autonomous and assistive defense applications look to squeeze increasingly complex computational tasks into smaller, more mobile systems.
Wireless Design 101: How to Reduce Costs and Achieve Better Performance

Wireless technologies for data communications and networking take on many forms to transmit data at rates ranging from a few kbits/s to more than 1.3 Gbits/s.
Cloud Computing: Not Just an Open or Shut Case

​Choosing a cloud platform has become a frequent and critical decision as more companies elect to offload their ineffective and expensive in-house data storage efforts. But selecting the right cloud computing platform involves many considerations, such as features, benefits and pitfalls that can have a big impact on how a company does business.
Wearables: Tracking, Computing and Making Sense of Context Awareness

Wearable devices are moving quickly from concept to reality based on evolving technologies such as sensor fusion, communications and vision. Wearables have evolved to become perceptually aware agents that learn through users’ experiences, activities and environment through observation via diverse physical sensors.
What’s Next for Lithium Power?

Li-ion batteries feature a high voltage, excellent energy density, a large number of recharge cycles and a slow self-discharge rate. The technology’s energy density allows manufacturers to produce batteries that take up much less space and are lighter than alternative chemistries of the same capacity.
Securing LED Networks in the Age of the Internet of Things

​Recently, in Nuevo Arenal, a little sleepy village in the Guanacaste region of Costa Rica, a dozen criminals cut the lights to the town’s main street during the quiet 3 a.m. hour, and then injured a gas station attendant, a hardware store security guard and a security guard hired by the town.
Electromechanical Relays 101: Versatility, Flexibility and Ruggedness

The electromechanical relay can be used to switch AC and DC signals as well as power; the control voltage on the coil and the load current through the switched contacts are isolated and independent circuits. As a result, this simple-to-understand component is well-suited to solving many applications and interface challenges.
FPGAs Support Bridging to Improve Design Efficiency and Reuse

Many designers may remember the early days of programmable logic when simple programmable logic devices (PLDs) such as PALs and FPLAs were used to replace SSI or MSI devices. Engineers could create their own IC that did just what they wanted.
3-D Printing Maximizes Design Flexibility in Defense and Aerospace

The aerospace and defense industries have long been developers, and early adopters, of cutting-edge technology. Aerospace and defense companies, for example, have been using 3-D printing (also called additive manufacturing) technologies for nearly three decades.
