Television & FM Antennas Gadgets & Gizmos
Researchers have created a new type of antenna made of liquid metal that can bend, stretch and twist, then return to its original shape, an advance in technology that could lead to new uses where resiliency is especially important--in the military, for example, or for rugged outdoor activities.

The scientists made the antennas by injecting an alloy made of the metals gallium and indium, which remains in liquid form at room temperature, into very small hollow channels the width of a human hair. They used elastic silicone channels to hold their alloy, and then fashioned wire-like antennas out of the material. The channels, which resemble straws that are open at both ends, can be manipulated into a variety of shapes.
Once the alloy has filled the channel, the surface of the alloy oxidizes, creating a “skin” that holds the alloy in place, while allowing it to retain its liquid properties. "Because the alloy remains a liquid, it takes on the mechanical properties of the material encasing it,” Dickey said.

Another discovery: "If you cut this device just through the metal--not all the way through--it comes back together," Dickey said. "You can partially damage it, and it will self-heal."
Since the frequency of an antenna is determined by its shape, "you can tune these antennas by stretching them," Dickey said.

WASHINGTON: Broadcasters stand to lose 40 percent of their spectrum under the FCC’s new National Broadband Plan, due on Capitol Hill tomorrow. The plan was released in Washington today; details emerged in several reports. The goal of the plan is to bring 100 Mbps broadband access to 100 million American homes in 10 years, nearly doubling the current reach of high-speed Internet access.
It calls for making 500 MHz of spectrum available in 10 years, and 300 MHz available within the next five years, for both licensed and unlicensed use. Of that, 120 MHz is to come from television broadcasters, who now occupy roughly 300 MHz.

Introducing the C‑SPAN Video Library. 160,000 hours of political events covered by the C‑SPAN Networks since 1987, with more added each day. Search it. Watch it. Clip it. Share it – all at no charge. Our Video Library lets you follow Washington your way – another public service created by America’s cable television companies.
WASHINGTON: The Cable-Satellite Public Affairs Network has now made their entire archive available on the Web site.
C-SPAN has now loaded up 160,000 hours of video, going back to 1987, on its Web site, with widgets for sharing on Facebook and Twitter. The database is now available online; a formal announcement is due on Wednesday.
The archives continues to record all three C-SPAN networks nonstop, indexing them and placing them in the database. Programs are indexed by subject, speaker names, titles, affiliations, sponsors, committees, categories, formats, policy groups, keywords and location. The congressional sessions and committee hearings are indexed by person with full-text.
Not all the resources are free of charge. All programs since 1993 are digital and can be viewed online for free. Duplicate copies of earlier programs can be obtained and used for education, research, review or home viewing purposes for a fee. Also, some programs are not copyright cleared for sale.
