Audi announces A2 electric concept car, uses lasers to ensure safety of future humans
Lasers make everything better, including (but not limited to): microphones, kidneys and Audi's electric A2 concept. This newest flight of fancy uses a laser diode as the rear fog lamp, which projects a red triangle onto the road to let other drivers know you're there. The German car-maker has tricked out the rest of the EV's lighting system as well by implementing matrix beam technology using LEDs and microreflectors -- giving it high resolution, non-glaring beams and intelligent tail lights that change in intensity based on weather conditions. Claiming other state-of-the-art features like gesture controls instead of keys, and brake lights that glow brighter the harder you press, it sounds like this would be a pretty sweet ride -- if it ever makes it to market. No word on the other, insignificant details (ya know, like what actually powers the thing) but there's plenty more about the car's lighting system in the PR after the break.
Sony releases 400mW-output blue-violet laser diode, could make BDXL blossom
Now that the BDXL spec is finalized, a handful of DVR announcements have trickled out to support the higher-capacity Blu-ray format. Sony's release of the SLD3237VF 400mW-output blue-violet laser diode, however, could flat-out open the floodgates. That's because, besides supporting the new larger capacity standard, it's the first diode of its kind to have an output of 400mW or higher. This gives manufacturers more flexibility in their hardware design to use a wider array of optical components. The cost for the part itself is roughly $12, but no telling what kind of premium it'll actually entail by the time it hits retail. We do know that all that additional memory should provide plenty breathing room for higher production 3D Blu-ray discs in the future, or enough HD bonus features space to make The Lord of the Rings extended edition box go on a serious South Beach diet.
Sharp and Nichia link up for LED patent cross-licensing deal
While RPTVs teeter on a bellbottom-styled return to the mainstream, Sharp and Nichia are focused squarely on the future. The two have just entered into a LED patent cross-licensing agreement covering both LEDs and laser diodes; the deal grants each company the right to use "inventions related to LEDs and laser diodes covered by the vast number of patents owned by the respective companies in Japan and in major countries." The release gets interesting when touching on Sharp's intentions -- it states that the company is hoping to "create unique, one-of-a-kind products in the future that feature both devices [Blu-ray recorders and LED lighting] at their core." Color us very intrigued.
Mitsubishi Chemical to produce laser diodes for BD pick-up heads
Given that Sharp will obviously be needing a few high-power laser diodes to go into its forthcoming 8x Blu-ray burners, it's good to see Mitsubishi Chemical hopping in the fabrication game in order to lower costs and keep consumers smiling. A new report asserts that the previously mentioned company will be dedicating at least some of its efforts to producing high-power (200 to 300mW) laser diodes, which are currently in short supply and used in the pick-up heads of BD writers. As it stands, just Sony, Nichia and Sharp are producing these things in volume, though a fourth wheel will certainly be welcome. There's no word on when exactly Mitsu Chemical plans to ramp up production, but the sooner the better, we say.
