Slideshow: Rambus lights up GuitarMania Blog 5/27/2012 3 comments 10-foot Fender Stratocaster guitars showed up in front of the Rock and Roll Hall of Fame and Museum in Cleveland this Memorial weekend. Among them was a guitar illuminated with LED lights, developed by Rambus engineers.
OLED – raising lighting to a new level Design How-To 5/21/2012 5 comments If silicon-based LEDs represent the state of the art in lighting, OLEDs will be the next generation. The article gives an overview on what is possible with this type of illumination.
PPS messaging connects HTML5 and hardware Design How-To 5/17/2012 Post a comment HMIs developed with HTML5 reside in a high-level, virtualized environment but still need to access hardware. In mobile devices, for example, they need to retrieve the device orientation and, if there are GPS or accelerometer chips, information these chips provide for applications that use geo-location. In-vehicle systems need to retrieve even more information from low-level components such as the CAN bus, GPIO pins, and I2C and SPI devices. Persistent Publish/Subscribe (PPS) provides a simple, e
Renesas PS9924 and PS9905 optocouplers Product News 5/17/2012 Post a comment Renesas launched two IC-output optocouplers with long-creepage-distance for applications such as industrial equipment employing the maximum commercial power supply voltage of 690 V or solar power generation systems employing high voltages of up to 1,000 V.
Fairchild Semiconductor FOD8320 Product News 5/10/2012 Post a comment Fairchild Semiconductor has developed an advanced 2.5A output current gate driver optocoupler, which offers a compact footprint while allowing for a creepage and clearance distance greater than 10mm and 0.5mm internal insulation distance.
Fraunhofer makes mini-projector for smartphones Research 5/8/2012 9 comments Researchers at the German research institution Fraunhofer IOF have developed an array of hundreds of microprojectors that can be used to project images from smartphones and similar small devices. The array enables the design of slim LED projection systems which nevertheless offer bright images even on curved screens.
Project e-smart, Pt. 2: Vehicle controls, modeling, and simulations Design How-To 5/8/2012 Post a comment Converting a Smart ForTwo into an EV includes planning and specifying requirements for the electric vehicle, electric components selection, and E/E-architecture and control software design as well, as implementation of hardware and software by students of the University of Stuttgart. This part describes the vehicle control system; measurements, modeling and simulation of the vehicle; and an outlook on future EV issues.
Power device consideration for optimized design of LED power supply Design How-To 5/3/2012 2 comments Switch-mode power supplies for LED lighting applications are increasingly being designed with an active power factor correction (PFC) at the input stage to meet international regulations for harmonics. The boost topology in discontinuous current mode is most suitable PFC method for converters less than 300W power rating.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
