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.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
