Sunlight sensors detect the amount of solar radiation to improve air conditioning efficiency and provide a higher comfort level for driver and passengers in vehicles with separate cooling zones. Hamamatsu's S8369 sensor uses a photodiode to measure the infrared heat load of the sun's rays and a special cap shape to achieve a wide-angle of directivity. The one-piece plastic package design integrates the sensor assembly and connector in a single housing. The unit has a spectral response from 320 to 1100 nm. To meet passenger compartment requirements, the sensor has an operating temperature of -30 to +80C. Custom versions address different specifications, including multiple zones, and added functionality. For more information on Hamamatsu's sunlight sensor go to: http://rbi.ims.ca/4914-501
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
