SENSORS: Kavlico’s newly released combined pressure & temperature sensor is for use with the natural refrigerant R744 (C02) for pressure and temperature sensing in mobile air conditioning systems. This rugged, low-cost sensor has a 17-4 PH hermetically sealed, stainless housing. The sense element is based upon Kavlico’s patented TiON (Titanium OxyNitride) thin film technology which is capable of withstanding high media temperatures. The sensor’s high operating pressure range of 0 to150 Bar with a proof pressure of 210 Bar and a burst pressure of 320 Bar is well-suited for this demanding application. The operating process media temperature range is -40 to 180C, while the ambient operating temperature is -40 to 135C. Highly stable and accurate, the sensor can be specified with either an analog, SPI, LIN2.0 or CANbus output. The sensor tolerates high vibration environments and has built-in reverse polarity protection, as well as over-voltage protection.
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.
