A miniature all-purpose push-button photoelectric sensor has been introduced. The new EZ-EYETM has been designed to perform a multitude of sensing applications including object detection, Web break detection, counting, inspection, orientation, and more. Features include setup with the single push of a button, flash rate indicator for easy alignment, higher gain adjustment by tapping button, sensing mode optical block selection, infrared (IR) or red LED light sources, both NPN and PNP output transistors, pulsed modulated light source that is immune to most ambient light including strobes, and 10 to 24V dc power supply requirement.

In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
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.
