SENSORS: Kavlico, a global business unit of Custom Sensors & Technologies (CST), has designed a sensor to measure common-rail pressure in diesel engines. The advantages of monitoring common rail pressure are many; including increasing engine power and torque, improving fuel economy, reducing engine noise, and improving vehicle drive-ability while creating cleaner exhaust emissions. With today’s restrictive emissions standards, keeping exhaust particulate emissions within the mandated levels is a must … and Kavlico’s common-rail sensor is an essential element of the common-rail injection system.Pressure is regulated and monitored by the Electronic Diesel Control Unit (EDCU) which receives an electronic input from the Kavlico pressure sensor. The sensor operates on 5V dc and provides a 0.5 to 4.5V dc linear amplified analog output proportional to pressure to the EDCU. The highly accurate and ruggedly designed sensor uses a thin film TiON sense element which provides highly reliable and repeatable measurements.
The cost-effective sensor is EMI/EMC protected, has low power consumption, and is capable of operation in high vibration environments. Fully temperature compensated across the entire measurement range, the sensor has an operational temperature of -40 to 125C.
Pressure ranges are available from 0 to 3,000 Bar or 40,000+ PSI. The sensor can be customized to accommodate a wide array of pressure ports and electrical connector options dependent upon each OEM application-specific requirement. Alternative pressure ranges and output formats are also available upon request.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
