ELECTRONICS/SENSORS: Honeywell has expanded its ASDX plastic silicon pressure sensor family with the new ASDX Series and ASDX-DO Series, which offer pressure ranges from 1 psi to 5 psi. Onboard signal conditioning allows the customer to remove those components from their PC board to free space, may reduce their acquisition, inventory and assembly costs, and minimize potential problems from having multiple signal conditioning components spread across a circuit board. These low-pressure sensors are intended for use with non-corrosive, non-ionic working fluids, such as air and dry gases. Potential industrial and medical applications include barometry, flow calibrators, gas-flow instrumentation, sleep apnea/therapy equipment, pneumatic controls and ventilation/airflow monitors. The ASDX and ASDX-DO Series pressure sensors are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1 kHz.
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.
