The Navy has been granted the patent for a cavitation weapon. The powerful weapon would use sonar to generate "acoustic remote cavitation," that would destroy everything from torpedoes to mines. As the patent describes:
A method is disclosed of generating a predetermined field of cavitation around a remote target in an underwater environment. The method includes the steps of identifying a remote target location, generating at least two acoustic beams, each at a high power output, from an underwater acoustic source, and controlling the generated acoustic beams to intersect with each other at the remote target location and thereby create a destructive cavitation field at the intersection of the beams. The acoustic source and target can be located in unconfined underwater space and at a distance of at least 100 m apart.
The underlying physics is based on the intense heat and high-pressure pulse from the sonar sources 12, 14, and 16 as the damage mechanisms by virtue of the intense acoustic power of the sonar sources. An ensuing cavitation bubble formation and collapse and shock propagation will also inflict damages on underwater objects 18 targeted for removal. The technical drivers are the cavitation lethality on the undesirable objects 18 and the acoustic power of the sonar sources versus range and depth.

 | | brain wave-reading toys and video games |
Engineers at NeuroSky Inc are working on brain wave-reading toys and video games using Technology from NeuroSky. The company claims technology from NeuroSky and other startups could make video games more mentally stimulating and realistic. It could even enable players to control video game characters or avatars in virtual worlds with nothing but their thoughts.
During a recent press tour, NeuroSky showed off a prototype, years in the making, of a toy that incorporates brain wave-reading technology.
Behind a black mask, is a sensor that touches the user's forehead and reads the brain's electrical signals, then sends them to a wireless receiver inside a saber, which lights up when the user is concentrating. The player maintains focus by channeling thoughts on any fixed mental image, or thinking specifically about keeping the light sword on. When the mind wanders, the wand goes dark.

Consumer electronics company Philips has filed a patent for a Furry TV.
Philips says a single pixel can be made out of a piece of fabric covered with hair-like strands, which could result in a TV that is soft to touch. The company hopes to build furry displays into outfits

Industrial Design students, Gabriel Tan and Wendy Chua, both third year students from the National Univeristy of Singapore (NUS) won the Design Lab Award at the international Electrolux Design Lab 2005 competition for a waterfall-inspired washing unit that require neither water nor detergents.
Called Airwash, the waterfall-inspired washing unit is waterless and does not use detergents. Instead, it utilises negative ions, compressed air and deodorants to clean clothes. By using atmospheric air and negative ions - a natural cleansing agent - it fights dirt and bacteria with nature's own weapon. Airwash is also designed to be placed anywhere in the home, instead of the designated laundry area.

NEC LCD Technology, Japan has developed a 2.7" QVGA LCD that features a touchscreen by default, aimed at smartphones and PDAs. Sample shipments will begin in June for the cost of 9,000 yen.
The amorphous silicon color touchscreen TFT LCD is capable of displaying QVGA resolutions (320 x 240) in about 2.7 inches. While it retains a low power consumption of 220mW, it has a high contrast ratio of 400:1 and a brightness of about 180cd/square meter. More

Hitachi Global Storage Technologies, the second-largest disk drive maker, behind Seagate Technologies., is testing sample drives based on perpendicular recording and has claimed that the technology can allow for 1 TB desktop drives or 20GB Microdrives in 2007. Hitachi demonstrated the industry's highest data density at 230 gigabits per square inch (Gb/in2) on perpendicular recording. The company will later this year begin selling hard drives based on the yet-to-be commercialized recording method called perpendicular recording, this method arranges the north and south poles of the magnetic particles in a perpendicular fashion, unlike today's disks which use longitudinal recording. The perpendicular method packs more particles onto an area of the disk's surface, thus allowing for the greater recording capacity.

Designed for a future where diminished fossil fuels and increasing environmental responsibility have become important business drivers, the "E/S Orcelle" concept vessel based Wallenius Wilhelmsen's vision for the year 2025 would have a capacity of 10,000 standard cars and would use only renewable energy sources and naturally-charged fuel cells for power. The innovative vessel is named in honour of the Orcelle dolphin, currently high on the WWF's endangered species list.
