Rerouting Microwaves for Invisibility

Rerouting Microwaves for Invisibility More progress has been made toward an invisibility cloak that can operate over a broad spectrum. Researchers — including one who built the first invisibility cloak — have come up with a complex cloak invisible to a broad band of microwave light: 1 to 18 GHz. Key to the development is software that compresses time to design metamaterials, whose further refinement of nanostructured properties are deemed crucial to ultimately making a cloaking device that functions in the visible spectrum. Consisting of 600 I-shaped copper structures, the device shown reroutes microwaves over the broad spectrum.

Enlightening Speakers

Enlightening Speakers Here's a novel idea: a speaker-and-light combo. Designers have come up with an assembly that incorporates an 8 ohn Bluetooth replaceable speaker with LED lighting. The speaker can function either independently of or dependently with the light. Speaker control could be located at the light switch or alternately on the LED bulb with the Bluetooth receiver.

In Search of the Invisible Speaker

In Search of the Invisible Speaker Touted as the biggest speaker breakthrough in decades, a new loudspeaker technology utilizes a miniature-motor array to apply force to the sides of a thin membrane, thereby producing perpendicular sound waves. And, because the membrane is made of optically transparent material, the speaker is "invisible." You are actually looking through the speaker when viewing an image on a flat-panel TV, computer monitor, or display. In operation, the bigger the screen, the better the sound.

Acoustic Panels Let You See Stars

Acoustic Panels Let You See Stars These sound-control panels deliver not only an acoustic solution, but also an optical experience that mimics a view of all the stars in the sky. Utilizing fiber optics, these acoustical panels can make a ceiling look like the night-time sky. While they are suggested for use in home theaters without affecting a big screen image, lots of indoor workers would undoubtedly prefer them vs gray, cloudy days.

Cheap Nanowire Sensors

Cheap Nanowire Sensors Nanowire sensors have been made in a laboratory setting, but the shortfall to mass production has been placing the wires precisely in position on a silicon chip. Now Penn State researchers may have solved the problem by utilizing an electric field. The process involves guiding single nanowires into position. Once that's done, electrodes are deposited on top to create an array of sensing devices. Such sensitive sensors could rapidly scan for pathogens, chemical toxins, or detect diseases at an early stage.

New Security Tool for Wi-Fi Signals

New Security Tool for Wi-Fi Signals Keeping wireless networks secure continues to be a concern for many. While encryption and other options are readily available, the trend toward using higher-frequency signals has made using typical iron-oxide paints — a relatively inexpensive solution — to block signals ineffective, until now. Japanese researchers have developed an aluminum-iron oxide formulation that absorbs 182 GHz electromagnetic waves, a capability about 4x higher than typical iron-oxide counterparts.

Stealthy UAVs

Stealthy UAVs Researchers at Georgia Tech Research Institute (GTRI) are analyzing acoustic signatures of unmanned aerial vehicles (UAVs) in an effort to make them more stealthy noise-wise. In operation, the remote-controlled vehicles often fly close to their designated reconnaissance and surveillance targets, making noise reduction a key requisite to avoid detection. To achieve their noise-reduction goals, aeroacoustics experts are investigating a multitude of solutions in a specially designed flight simulation chamber.

Backburner for Credit Cells in the U.S.

Backburner for Credit Cells in the U.S. In Japan (for five years now) and other countries, you can just wave your cell phone and pay for grocery, vending machine, and other purchases. Unfortunately in the U.S., even though consumers really prefer to pay this way as studies say, one major problem is impeding implementation. Who gets how much "moola" is the definitive hang-up. This article suggests at least a five-year delay while parties of the first part agree on how to divvy up the profitable pie. [A short registration may be required.]

Mobile Phone Recession

Mobile Phone Recession Worldwide the economic recession seems to be affecting all communications, handsets included. Nokia — the largest supplier of handsets — reports a 19% drop in fourth quarter sales to $16.5 billion. Correspondingly profits decreased by 69% in both low- and high-end products. As CNET News reports, sales this year are predicted to be down 10%. This financial bottom line will undoubtedly affect the timely intro of new technology. {sec8_editem2_text}
