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 DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
Barnacles and mussels stay attached to ship hulls and rocks because of a very sticky protein glue they secrete, holding on for a long time even underwater. Researchers at MIT took mussel glue as inspiration -- and as an ingredient -- for engineering their own sticky waterproof adhesive.
