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

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.
