MOTION CONTROL:Steinmeyer Inc.’s new precision linear stage, the PA 30×40-SM01 is a single axis system ideal wherever there is a need for an extremely narrow positioning table. Typical uses include miniature robotics, pick and place devices, specimen handling for life sciences and scientific applications where precision positioning is required within a very narrow foot print. This compact, fully enclosed stage is only 30 mm wide and 40 mm high. Available travels range from 25 mm to 150 mm. Positioning repeatability is 1 micron, maximum speed is 50 mm/s and load capacity is 100 newton. Included inside this precision assembly are a precision preloaded 8 mm diameter Steinmeyer ball screw, miniature size 9 linear guideway, non-contact limit switches and a choice of either stepper motor or dc servo motor with encoder. A separate motion controller is available as an option.
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.
