Oct. 26 - P. 5: Instrumentation for Power Measurement
Continuing Education Center 10/26/2012 178 comments Part 5 discusses available power-related instrumentation that may be applicable to many situations (multimeters, scopes, power meters, source measurement units, among others), as well as implementation issues in practical systems, including 2/4-lead measurements, noise, loops, and other issues.
Oct. 24 - P. 3: The Basics of Electrical Circuitry
Continuing Education Center 10/24/2012 175 comments Part 3 examines the electrical circuitry needed to interface the various sensors, safety issues for the system, the misunderstood term and concept of "ground," and floating/differential measurement situations.
Oct. 23 - P. 2: The 4 Most Common Transducer Types
Continuing Education Center 10/23/2012 238 comments Part 2 looks at the four most-used transducer types (shunt resistor, transformer coil, Rogowski coil, and Hall devices) and their key attributes and tradeoffs, use for AC vs. DC vs. transient power measurement, and low, medium, and high-power regimes.
Oct. 22 - P. 1: The Basics of Electrical Power Measurement
Continuing Education Center 10/22/2012 324 comments Part 1 of this course will define basic terms, explain why power (and energy) measurement is needed, clarify what will and won't be covered, and explore what the role and reality of power measurement is. It will also provide an overview of the remaining parts of the course.
Oct 10 - Part III: Fundamentals of Smart Sensors
Continuing Education Center 10/10/2012 195 comments Many technologies contribute to improving sensors that frequently get dubbed "smart sensors." The "smart" term is used loosely in many technical and non-technical areas, so what makes a sensor smart? Find out from our expert in this session.
Oct 8 - Part I: Sensor Specs 101
Continuing Education Center 10/8/2012 257 comments Obtaining the expected performance for a sensor in a system requires a solid understanding of the terms used to specify performance. In many cases, it is absolutely necessary to sort through the marketing hype about a sensor's capability, but even data sheets are non-uniform and can be confusing. In this course, our expert explains the essentials to avoid application pitfalls.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
The Window Watcher stops the burglar before he does damage or enters the house. House alarm service companies set off alarms and call the service only after the burglar has damaged and entered the house.
If you’re designing a handheld device or industrial machine that will employ a user interface, then you’ll want to check out the upcoming Design News Continuing Education Center course, "Engineering Principles Behind Advanced User Interface Technologies.”
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
