Conventional single-core fiber-optic cables require a minimum bending radius to achieve a 90(degree) turn without reducing the beam diameter and degrading the sensing distance. 12.5 mm is typical. Result: large cable loops that are subject to snagging, pulling, and crushing of the cable by passing objects.
Although competitors have cable with a 2-mm bending radius, Omron's multi-core fiber optic cables achieve a 1-mm bending radius by bundling more than 200 fiber-optic strands as the core. When the cable is bent into a sharp angle, the individual strands shift around within the sheath. This prevents kinking and tensioning damage when the cable is installed with tie wraps.

Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
