This brief interactive activity, by the Electromechanical Digital Library and Wisconsin Technical College System faculty, explains clearly the reasons to use switches in place of hubs when using an LAN. The animations and corresponding explanations are helpful as the user clicks through each slide...

This resource, presented by the Maricopa Advanced Technology Education Center (MATEC), is an animation that serves as an introduction to Human Machine Interfaces. According to the animation, a Human Machine Interface is "a way for an operator to access a machine." Types of Human Machine Interfaces...

These interactive learning objects, created by instructors from Fox Valley Technical College and other colleges in the Wisconsin Technical College program, focus on concepts that cover a broad-based electromechanical program. Here visitors will find learning objects in Hydraulics including Basic...

The ATETV project delivers web-based videos to connect students to careers in advanced technology. This episode of ATETV focuses on high school programs that help students make a seamless transition into college, how new simulation and game development skills provide an opportunity for a career...

The ATETV project delivers web-based videos to connect students to careers in advanced technology. This episode of ATETV focuses on just how much input community colleges receive from industry. The first part of the video, Making Sense of What You Are Learning, looks at electrical engineering...

This web-based learning object, created by Terry Bartelt of the Wisconsin Online Resource Center, teaches impedance matching. "Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity."

Terry L.M. Bartelt of the Wisconsin Online Resource Center provides this interactive study of the operation and characteristics of an incremental optical encoder used in automated manufacturing applications. A brief quiz completes the activity.

Refraction is an important behavior of light that can be used to explain the operation of lenses, prisms, and optical fiber, as well as natural phenomena such as rainbows and mirages. The index of refraction, or refractive index, is defined as the ratio of the speed of light in a vacuum to the speed...

In this video from the ICT Center, learn about the index of refraction and Snell’s law. Review a simple example of refraction, the speed of light in materials, and the formula for calculating the index of refraction. Explore a table of the refractive indices of common media and materials used in...

Presented on behalf of Galil, these videos, presented by "industry leader" Jacob Tal, provide information on topics such as modes of motion, dual loop compensation, piezo-ceramic actuators, microstepping, and more. These two-minute videos are "perfect for busy engineers that need quick solutions to...
