KRDB Series ultra-compact, encapsulated, low-cost time-delay relays are delay-on-break timers. Input voltage must be applied to the input at all times prior to and during timing. Upon closure of the initiate switch, the relay energizes and remains energized if no further action is taken. When the initiate switch is opened, the time delay is started. At the conclusion of the delay, the output relay de-energizes. The use of surface-mount components makes it possible to miniaturize the circuitry without sacrificing performance and reliability.

The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
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.
