The previous parts of this article looked at heat and thermal-physics principles, while this part looks at the basic structure if an A/C system using these principles. Carrier realized that he could leverage a counterintuitive paradox, that air could be dried by first being saturated with water. After all, fog is air which is nearly […]

Fuel cells for backup power, microgrids and renewable energy
Fuel cells are increasingly being used in stationary power applications such as backup power, microgrids, and renewable energy systems. This is part two of a three-part FAQ series and digs into a wide variety of fuel cells in stationary power applications ranging from low power systems for residential backup power to the use of large-scale […]
Measuring the performance of AI and its impact on society – Virtual Conversation (part 2 of 2)
Hosted by Jeff Shepard, EE World has organized this “virtual conversation” with Gary Bronner (GB), Senior Vice President with Rambus Labs. Mr. Bronner has generously agreed to share with us his experience and insights into AI applications and emerging computing architectures. JS: When benchmarking AI performance, how would you rank the importance of throughput, latency, […]
The development and implementation of air conditioning, Part 2: The A/C concept
We take air conditioning (cooling plus humidity control) for granted, and its development is largely due to one man’s “flash” of insight related to thermal principles and basic physics. Part 1 of this article reviewed basic thermal and heat concepts and measurement units related to air conditioning; this part looks at the development of such […]
Fuel cell technologies and operating characteristics
There are over 20 categories and subcategories of fuel cell technologies. This article will review several of the most common fuel cell technologies, especially as related to commercialization. This is the first of a three-part FAQ series. Part two will look into “Fuel Cells for Backup Power, Microgrids and Renewable Energy” and part three will […]
The development and implementation of air conditioning, Part 1: Heat principles
We take air conditioning (cooling plus humidity control) for granted, and its development is largely due to one man’s “flash” of insight related to thermal principles and basic physics. It’s hard for us today, with the ubiquitous air conditioning (A/C) and mechanical refrigeration we enjoy effortlessly, to grasp how A/C changed our lives: it made […]
AI applications and emerging computing architectures – Virtual Conversation (part 1 of 2)
Hosted by Jeff Shepard, EE World has organized this “virtual conversation” with Gary Bronner (GB), Senior Vice President with Rambus Labs. Mr. Bronner has generously agreed to share his experience and insights into AI applications and emerging computing architectures. JS: What is usually the biggest challenge designers face when first using artificial intelligence? GB: One […]
Basics of measuring fuel cells
A fuel cell converts oxygen or another oxidizing agent and hydrogen or some other fuel into electricity and heat. A third byproduct, depending on the fuel used, is methane or another non-earth-friendly substance. But the most basic fuel cell combines hydrogen and oxygen to produce pure water. This simple, long-lasting device with no moving parts […]
Embedded systems software and programming for a safer world
Functional safety is an important feature in many embedded systems today. Designers need to know the specific safety integrity levels that must be met in various application environments and software development standards and guidelines. The use of an integrated development environment can efficiently bring these various requirements together to maximize the productivity of the development […]
Securing embedded systems in a hostile world
The design of security for embedded systems is a critical and difficult task. Security requirements are often not fully identified at the beginning of the project. Once they have been identified they are not necessarily static and can change multiple times through the design cycle. One reason for changing security requirements is that the various […]
