ELECTRONICS/SENSORS: Melexis‘ MLX90109, its single chip, low-frequency (125 kHz) RFID transceiver, was selected by Somfy for use in a security application for homes and buildings. Originally designed for an automotive immobilizer application, the MLX90109 fits also industrial requirements in access control or pet identification. Although the big trend in contactless authentication is high-frequency RF communications (13.56 MHz), there are applications where low power, robustness and space constraints call for low-frequency contactless authentication. In all these cases, the MLX90109 is the key element for an optimum solution.
The MLX90109 was successfully designed-in at Somfy for its alarm control terminal. It is available in volume production together with an evaluation board and a development kit to speed up the development cycle of the customer. The transceiver chip is offered in a 0 to 70C version and a -40 to 85C version in the industry-standard SO8 pin package for surface mount manufacturing. Estimated pricing for the MLX90109 is 0.98 Euros at 50,000 pieces quantity.
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.
