ELECTRONICS: In the new Audi A8, light emitting diodes from OSRAM Opto Semiconductors are responsible for the low and high beams as well as for other specific lighting functions. Apart from their efficiency and long operating life, LEDs offer enhanced driver safety through improved visual contrast, warmer color temperature, and active electronic control.Among the most striking features of Audi’s current vehicles are the LED daytime running lights installed in the headlamps. In the new top-of-the-line A8, OSRAM OSTAR LEDs have now advanced headlamp lighting beyond simple low and high beams. Special lighting functions such as motorway beams, cornering lights and all-weather lights are now handled by LEDs. The technological progress is readily identifiable - the individual light sources are visible in the headlamps, noticeably distinguishing the Audi from other automobiles at night.
The OSTAR headlamp is available as a new product platform with up to five LED chips. An innovative conversion process provides a seamless white color impression at maximum brightness levels. Typical light values achieved for each LED chip are 160 lm at 700 mA. Depending on the variant and operating current, values between 125 lm and 1100 lm are achievable. With its scalable brightness, the OSTAR headlamp is perfectly suited to all headlamp functions such as low and high beams, cornering lights, fog-lamps and even for use in daytime running lights.
The use of LEDs also increases driver safety. The OSTAR headlamp LEDs fitted in the A8 illuminate the road surface with perfect definition, without glare, and they produce a light similar to daylight, which enhances perceptions of contrast. In the peripheral field of vision especially, i.e. where pedestrians, animals or poorly lit vehicles may suddenly appear at night, it is easier to recognize objects with white LED light. Even potholes, obstructions and worn road markings are much more visible. Another benefit is that the color temperature is close to that of sunlight, so a driver’s eyes will not tire so quickly. Essentially, this technology has the potential to prevent numerous nighttime accidents.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
