ELECTRONICS:W. L. Gore & Assoc. Inc. has developed a 10m SFP+ copper cable assembly that is fully compliant with the SFF-8431 Revision 4.1 specification. Gore’s SFP+ (Small Form-factor Pluggable) offering can go 3 to 5m longer than other passive options and provides a lower cost alternative to power-consuming and heat-generating SFP+ transceiver modules. In comprehensive internal testing, Gore is the only cable assembly vendor who has demonstrated this use length while still complying with the SFF specification for 10 Gbyte/sec (10 GbE, 10 FCoe).Through the use of patented GORETM EYE-OPENER+® Conductor Technology and an extremely low loss expanded PTFE cable dielectric, Gore is able to balance the dWDP (waveform distortion penalty) and VMA loss (voltage modulation amplitude) parameters to achieve results within the specification limits set forth by the SFF-8431 committee. Gore has demonstrated typical values for VMA loss of 3.95 dBe and a dWDP of 5.60 dBe. The SFF-8431 specification calls out maximum limits of 4.40 and 6.75, respectively.
Gore’s proprietary expanded PTFE is branded as GORE-TEX® in the fabrics market.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
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.
