Laser System Paints Information on the Road Ahead

Cheaper green semiconductor lasers could bring a novel display technology to market.

Head-up displays
, which project visual data onto the windshield and the driver's view of the road, are debuting in a growing number of car models. But more vibrant, compact, and efficient displays being developed by Microvision
, a company based in Redmond, Washington, could help the technology become much more common. Japan's Pioneer Corporation
plans to release its first head-up display product based on Microvision's novel display technology this year. Major carmakers in Detroit are also planning to integrate the technology into their vehicles by 2016, says Lance Evans, a director of business development at the company. Microvision's image projector
relies on semiconductor lasers and a microscopic mirror. The company's head-up display is already in some concept cars but has so far been too costly for commercial models, says Evans. Now, falling prices of green lasers—a significant cost component of the display—should make the technology competitive with conventional displays, he says. Most existing head-up displays generate images using LCDs. Light-emitting diodes produce light and liquid crystal arrays act as shutters, controlling whether or not light reaches each pixel. This approach drains power, and the images often aren't bright enough to be visible in daylight. Newer displays use either liquid crystal devices or hundreds of tiny mirrors to reflect light onto each pixel. While more energy efficient, these displays are still not very bright. Microvision's system uses a set of three lasers—red, green and blue—and a single, millimeter-wide silicon mirror that tilts on two axes. The lasers put out light at different intensities, and the three colors are mixed to produce the final pixel color. As the lasers shine light on the mirror, it rapidly scans horizontally and vertically, painting the image onto the windshield one pixel at a time. This happens so fast that the image looks static. Evans says that the lasers' pure, saturated colors result in more vivid images with a higher contrast ratio, so they are visible in daylight. Illuminating one pixel at a time also saves energy. And the use of a single mirror rather than an array makes the device smaller, simpler, and cheaper. The final cost of Microvision's product will hinge on the price tag of advanced green lasers. Materials for true green lasers have traditionally been difficult to engineer, so most green lasers contain semiconductors that emit infrared light, which is converted to green using complicated optics. In the past few years, though, half a dozen key players, such as Nichia
,Osram Opto Semiconductors
, and Soraa
, have developed cheaper pure-green lasers. They're slowly scaling up production, which should lower costs. Evans expects that costs should fall to a tenth of current levels by the end of this year. "Green lasers alone are $200 each now," he says. "Car companies are looking at the whole display to be that much." Microvision's laser-scanning display technology beats its competitors in terms of image quality, says Krishna Jayaraman, an analyst at Frost & Sullivan
. While other companies are also developing laser-based head-up displays, Microvision was the first to propose the approach and has a technology lead. Chris Chinnock, president of the display market research firm Insight Media
, points out that mobile connectivity is on the rise, and drivers need more and more information to be displayed in the least distracting way possible. That means the head-up display market for cars could be on the cusp of significant growth.
GE's New EV Charging Stations Are Not Ugly

Stylish charging stations are one small step toward getting consumers to accept EVs.

GE's Wattstation electric-vehicle charging station went on sale this week. The most notable thing about it is its appearance. Unlike many other charging stations on the market now, this one isn't ugly. It looks like the sort of thing you might want to plug a $40,000 electric car into.

...rial Ethernet Switch from Korenix is ideal in dusty or dirty scenarios. Information won`t be interrupted at all when this type of switch is in action and you can imagine that the services provided by the switch in such harsh conditions have to be 100% accurate all of the time. The Industrial Ethernet Switch can work with superior software that can provide essential information for workers in the mine. They`ll need to know when the mine can be accessed and when they can carry out their duties. If you need an Industrial Ethernet Switch that will perform well in harsh conditions then Korenix could be the company that you will need to contact in the future....

Therefore precautions need to be to be taken when it comes to disposing of old laptops and the hard drive destructionshould involve a proven method. If you have ever tried to destroy a laptop drive yourself in the past you`ll know what a problem this can be. Software is often used in this process but can you honestly say, hand on heart, that you fully trust this method? One way to ensure that the hard drive destructionis carried out in the correct manner is to have drives destructed inside an industrial shredder. This can be completed before your own eyes as portable shredders can be brought to the work place by firms who specialise in this process. Up to 25 drives...

Wild birds will be caught in all their glory when these magnificent magnifiers are used. From great distances ornithologists can view a number of species when they have their Binoculars hung around their neck. Other types of hobbies will also require equipment that can make objects seem clearer from afar. Plane spotters will use observation equipment when they are near the airfield. How else can they tell what`s coming in to land or what`s about to take off from the runway?

Within this case, these blades are held a particular distance apart while the case protects the contacts from corrosion because outside air can`t reach inside. The contacts extend outside the case where they are connected to any suitable appliance. An ordinary rubber insulates the wiring outside the case. Some of the reasons why using a reed switch is feasible is because it is small and of convenient size, had low weight but a minimal response period, can be used in more than 45 million operations, and, is cost effective. There are different types of reed switches including Mercury reed switches, High Voltage reed switches, Dry reed switches, and High Power Switch Modules. Depending on the use you have, each of these has its particular use. Generally, a reed switch be can used in robotics sensors, secu...
