Say goodbye to half-empty boxes: Packaging machine sizes cardboard just right
Packaging machinery automatically cut corrugated cardboard into boxes sized for incoming product. The box forms around the product. Servomotors and drives let special packaging machines correctly size corrugated cardboard boxes for any product, so there's no need to fill empty box space with extra cushioning material.
Shock at the coffee shop 2

I may have ruined dinner for someone awhile back. It all began when table conversation at a dinner party turned to coffee shops and, more specifically, disposable coffee cups. The woman on my right was convinced the paper cup she used for her morning latte was completely recyclable and should go in a recycle bin.

Magnetic refrigeration heats up

The traditional vapor-compression cycle used in refrigeration may be relegated to the history books if researchers are right about magnetic (magnetocaloric) refrigeration. At least one major appliance maker plans to commercialize magnetic refrigeration for use in the home. The rationale for the change is that the technology uses no refrigerants or compressors and is said to be 20% more efficient than conventional techniques. It could also work well in HVAC.

Propeller gets immortalized in digital data 1
A digitizer captured the dimensions of one of the propeller blades on the fishing vessel named Harmony. A laser tracker helped measure a 25-year-old propeller in just a few hours as a means of generating a CAD model from which copies could be made.
Modular connector makes stage equipment simpler

The end of the semiconductor industry? 3


When Janusz Bryzek, vice president of MEMS and Sensing Solutions at Fairchild Semiconductor Inc., isn’t busy starting companies, he is engaged in saving the world. Or at least that is one interpretation of his recent endeavors toward a concept called the Trillion Sensors Movement. Bryzek, who received his MSc and PhD degrees from Warsaw Technical University, co-founded (among others) sensor makers SenSym, IC Sensors and NovaSensors in the 1980s, and Jyve Inc. in 2009 which Fairchild eventually acquired.

Could engineering school be free? 2
Could you replace an entire semester of engineering school with free Massive Open Online Courses (MOOC) equivalents?
Gallery: Weird 3D printing machines of the week 1

If you think the world of 3D printing has pretty much settled on ink jet printing technology for creating additive parts, guess again. This past week saw a variety of odd-ball additive techniques getting notice. Some of them are experimental, and time will tell whether some of them will lead to techniques that are useful for mainstream users.

That’s entertainment: State-of-the-art controls for state-of-the-art shows
Picture a Las Vegas show where performers fly through the air or do backflips on moving platforms. Ten years ago, controls handling the advanced equipment involved in these feats were likely to look a lot like the programmable-logic controllers (PLCs) found on packaging lines or assembly operations. Today, that situation has changed dramatically. High-end theatrical productions are typically orchestrated by specialized software packages running on PC hardware that, in their own way, are the equal of the electronics running industrial processes.
Scenes from MD&M West 2014

The Medical Design & Manufacturing exposition kicked off Monday Feb. 10. Here are some of the technologies that were in evidence there.
