Whereas the signal-processing and image-reconstruction techniques used in medical ultrasonography have made huge advances since this type of imaging became commonplace three decades ago, the business end of the apparatus—the transducer, which converts electrical impulses to sound waves and vice versa—has remained largely unchanged. So we found fertile ground when we began digging for ways to improve those transducers using tools from the microelectronics industry. You will soon find the fruits of those efforts at your local hospital. Indeed, this strategy promises to revolutionize ultrasound imaging within the next few years.

25 Microchips That Shook the World
In microchip design, as in life, small things sometimes add up to big things. Dream up a clever microcircuit, get it sculpted in a sliver of silicon, and your little creation may unleash a technological revolution. It happened with the Intel 8088 microprocessor. And the Mostek MK4096 4-kilobit DRAM. And the Texas Instruments TMS32010 digital signal processor.
Among the many great chips that have emerged from fabs during the half-century reign of the integrated circuit, a small group stands out. Their designs proved so cutting-edge, so out of the box, so ahead of their time, that we are left groping for more technology clichés to describe them. Suffice it to say that they gave us the technology that made our brief, otherwise tedious existence in this universe worth living.

U.S. May Monitor Pirates From Space
The U.S. is exploring the use of commercial satellites to enhance ship identification and communication for the battle against piracy.
Long before the U.S.-flagged container ship Maersk Alabama was attacked by Somali pirates this month, a sister vessel, the Maersk Iowa, was plying the sea lanes between the U.S. East Coast and the Indian Ocean, testing a device that combines the information obtained from shipboard radar and identification transponders to give authorities a better overview of who is on the water and what they are up to.

Hypersonic ‘WaveRider’ poised for test flight
Hoping to bridge the gap between airplanes and rocketships, the U.S. military is preparing to test an experimental aircraft that can fly more than six times faster than the speed of sound on ordinary jet fuel.
Officially, it's known as the X-51, but folks like to call it the WaveRider because it stays airborne, in part, with lift generated by the shock waves of its own flight. The design stems from the goal of the program — to demonstrate an air-breathing, hypersonic, combustion ramjet engine, known as a scramjet.

JHMCS: Fighter Pilot “Look & Shoot” Helmets’ Upgrade, Ups & Downs
The Joint Helmet Mounted Cueing System (JHMCS) projects visual targeting and aircraft performance information on the back of the helmet’s visor, including aircraft altitude, airspeed, gravitational pull, angle of attack, and weapons sighting, enabling the pilot to monitor this information without interrupting the field of view through the cockpit canopy. The system uses a magnetic transmitter unit fixed to the pilot’s seat and a magnetic field probe mounted on the helmet to define helmet pointing positioning. A Helmet Vehicle Interface (HVI) interacts with the aircraft system bus to provide signal generation for the helmet display. This provides significant improvement for close combat targeting and engagement.

Fastest Camera Ever Built Uses Lasers
cientists have made the fastest camera ever. It can take 6.1 million pictures in a single second, at a shutter speed of 440 trillionths of a second. Light itself moves just a fraction of a centimeter in that time.
The camera works by illuminating objects with a laser that emits a different infrared frequency for every single pixel, allowing them to custom-amplify a signal that would otherwise be too dim to see.

Boeing ponders “variably” manned aircraft
Boeing has filed for a US patent on an aircraft control system that could be configured for two, one or zero pilots. The no-pilot mode would receive input from a remotely located operator by way of wireless signals, patent application 20090105891 states.
The development echoes similar work that Sikorsky has said it is performing. Sikorsky president Jeff Pino has said the company will increasingly turn to fly-by-wire designs in part to allow the military to use helicopters for missions too dangerous for pilots or for situations where pilots are injured. "We envision a switch in the cockpit of all of our helicopters with indicators for 'No pilot', 'One pilot' and 'Two pilots'," Pino stated at the February 2008 Helicopter Association International Expo.

Army ‘Multimode’ Raygun Tech Zaps, Crackles, Pops
The Army’s new ray gun research project combines the zap of a laser with the crackle of an electric shock and the pop of a high-power microwave pulse. Known as the Multimode Directed Energy Armament System, it offers a wide range of different effects against different targets. Defensively, it could knock out everything from improvised explosive devices to incoming rockets. As a weapon, its effects might range from Taser-like effects to a lethal lightning bolt — and it should be able to stop vehicles in their tracks.

Raven Small UAV Demonstrates Persistent Surveillance Capability on a 30 Hour Mission
Attached to the forward echelons and operated by the troops, Small Unmanned Aerial Vehicles (SUAV) have become a common element of support to the fighting units, providing a broad range of services to the warfighter, from intelligence gathering and target acquisition to battle damage assessment and force protection. Indispensable as they are, SUAV have one clear drawback – short range and mission endurance. System developers are aiming at extending their mission endurance, by energy saving and use of more efficient power sources. A new concept utilizing multiple SUAVs on a single mission enables a unit to maintain persistent monitoring of a mission area over a long time.

Tracking Internet Chatter Helps Spot Swine Flu Outbreak
Tech tools for tracking disease outbreaks have been useful for following the spread of swine flu and one startup even claims to have recognized the severity of the outbreak in Mexico before government public health officials.
Veratect, a Seattle-based biosurveillance startup, claims they alerted the Centers for Disease Control to the situation in Mexico — where health officials suspect swine flu has killed up to 149 people — on April 16, before even the Mexican health authorities declared a problem.
How’d they get ahead of the outbreak? By monitoring and analyzing the flow of social media traffic along with more official reports, the company’s CEO said.
“We started picking up the early indicators of social disruption, whether it shows up on blogs or Twitter,” said Bob Hart, the CEO of Veratect. “We can pick up the first indicators of behavioral changes.”

Chinese Navy Requires Supercruising Fighter
A supercruising combat aircraft is a high priority of the Chinese navy, the country’s top admiral says in a revealing official interview that gives strong clues of perceived shortcomings and future directions for the maritime force.
Adm. Wu Shengli also says China must step up work on precision missiles that can overcome enemy defenses, and the nation should move faster in developing large combat surface ships—probably meaning the aircraft carrier program that looks increasingly imminent (AW&ST Jan. 5, p. 22).

Little Black Box Streams HD Content Like a Flash Flood
Practically every device in my house (save for the counter-top fryer) doubles as a media streamer, blasting movies, music or even photos from one side of the house to some screen on the other. The SageTV HD Theater is different, though: It's smaller, cheaper, quieter and in some ways more versatile than most media streaming appliances. At roughly 7 inches wide and 6 inches deep, the HD Theater is smaller than a teacup poodle in a trash compactor. In fact, it's so small that it might even have trouble standing up to its own remote, if the two ever came to blows. Once the HD Theater was patched into my 42-inch plasma, it became clear that it's really two devices in one. Its first function is as an extender for viewing media stored on a computer. Like the HD100 Media Extender reviewed last year, the crux of this function is SageTV's included DVR software. Getting the software installed and converting my favorite home theater PC into a de facto media server was a cinch. Surfing through my networked media was easy enough using SageTV's plain (but customizable) interface, and even full 1080p playback was both brisk and clear. Also, since the HD Theater supports a ton of audio and video formats, it had no problems even when I threw it some tough file formats (MKV anyone?).

Self-healing concrete
A concrete material developed at the University of Michigan has the ability to heal itself when it cracks. Its developers claim that just a handful of rainy days would be enough to mend a damaged bridge made of the new substance. The new material heals itself because it has been designed to bend and crack in narrow hairlines rather than break and split in wide gaps, as traditional concrete does.
Stronger silk
Spider silk is tougher and lighter than steel - German scientists have added tiny amounts of metal to spider silk to make it even stronger and more elastic.
The technique could lead to the development of super-tough textiles, surgical thread or artificial tissues such as bones or tendons, the researchers claim.
To make the silk, the researchers borrowed a trick from nature with the goal of further enhancing its properties.
