And since ultrasound travels in a tight line akin to laser light, the emergent tones are audible only in a narrow, cylindrical path from source to ear.
The U.S. military has also invested in a range of flexible solar-panel technologies designed to power everything from night vision equipment and image intensification devices to laser-range finders, battlefield-ready laptop computers.
FORBES: Solar Power Brings NetCentric Warfare to Afghanistan
"All the optics that are applicable to laser printers, you could use to scan the surface of something, " says Bruce, who works on FAST with five people from PARC and three people from Scripps.
The FAA attributes the massive increase in incidents to laser pointers being more widely available online, stronger power levels, and an increase in green lasers which are easier to see, as well as better reporting of the incidents by pilots.
The laser is also much faster than electrolysis, the only truly permanent treatment on the market: It takes two one-hour sessions to laser off a mans chest hair, while electrolysis would take at least a year of unpleasant weekly visits.
Scientists at NASA decided to test their ability to communicate via laser to the Lunar Reconnaissance Orbiter (LRO) by sending an image of the famous painting.
Since this device is already commonly employed to cool laser diodes, adapting it to control the new switches in bulk should be a cinch.
So CIOs have to bring that laser focus to deciding where I want to innovate, and where I need to spend.
Moreover, engineers have worked out how to make laser beams more intense by using short lengths of optical fibre to narrow the beam.
It just became possible, thanks to a laser camera developed by physicists at Heriot Watt University in Edinburgh, UK. You can pretty much see how it works from the images above -- laser beams are bounced off the target and the duration of their return journey is measured precisely enough to detect millimeter depth changes even at extreme distances.
ENGADGET: Laser scans objects in 3D from half a mile away, scientists just need reason to use it
Nasa has been linked to an Earth-based laser to push debris to up to safety or down to destruction.
BBC: NEWS | UK | Magazine | One giant (scrap)heap for mankind?
Dr Page said the laboratory had a number of sophisticated microscopes which will be available to Pauline including a confocal laser scanner, which is a microscope which uses a laser to illuminate and fluoresce.
And an optical mission to test laser relay capabilities from earth geosynchronous (GEO) orbit will soon follow.
FORBES: Future Of NASA's Aging Deep Space Network Lies In X-Rays And Lasers
All-optical switches use micromirrors, which were originally developed to bounce laser beams around the surface of a silicon chip.
In mid-December, the company was granted a new U.S. patent protecting key areas related to its laser pulse technology.
Information about each layer is transmitted from the computer to a laser beam, which melts the PCL into a 3-D structure.
New attractions on Liberty Island will also include introductory guides to the statue using laser lights to pick out certain features.
The large robotic arm, which is connected to a laser cutting tool, can be manoeuvred around tight spaces in hazardous environments.
So I want to end by directing your attention to the laser eye surgery, another medical procedure typically not covered by insurance.
The reason Bose-Einstein condensates may prove useful outside the laboratory is that they are to matter what a laser is to light: all their constituent particles march in step.
ECONOMIST: A new way has been devised to make a peculiar form of matter
With mobeam's technology, the Galaxy S4 can "beam" traditional 1D barcode data to any laser scanner with no new equipment, such as optical scanners or backend systems, required by the retailer.
ENGADGET: Samsung partners with Mobeam to offer scannable bar codes on the Galaxy S 4
The stated intention in Washington was to pass laser-guided legislation targeted only at wealthy families, but there apparently was some confusion between the pilot and the weapons officer, because the collateral damage will be felt in all American households, rich and poor.
Ours is on a rack too shallow and low to accommodate a laser printer, and placed out of the way to minimize interference with the signal from TV sets, cordless phones and microwave ovens.
For hard-to-reach spots, the vehicle's ChemCam uses a laser to vaporize thin layers of rock.
After that, Starkweather and Goldman had an idea for getting the laser printer to market quickly: graft a laser onto a Xerox copier called the 7000.
Another laser that came close to being practical enough to use was the Tactical High Energy Laser, also known as the Nautilus laser (pictured above), which was designed to shoot down incoming artillery rounds.
To record over an existing recording, the amorphous spots are reheated by the recording laser to a temperature that allows them to recrystallise.
This is made possible by the fact that Blu-ray uses a 405nm laser to read its 0.1mm deep info layer, while HD DVD uses the same blue laser wavelength at the depth of 0.6mm.
ENGADGET: Three's company: Warner patents all-in-one hybrid disc HD
Next year, NASA is to launch a demonstration mission to test optical laser communications in conjunction with the LADEE (Lunar Atmosphere and Dust Environment Explorer) mission to the moon.
