Israeli Company Offers Free Tsunami Alert System

Filed under: — Aviran Mordo

JERUSALEM (Reuters) - An Israeli company said on Monday it planned to distribute free to Asian countries hit by last week’s tsunami a device it says could save lives by warning holiday-makers directly that a tidal wave is coming.

The system developed by Israeli inventor Meir Gitelis uses land and water sensors, smaller than a shoe box and each costing $170, to measure seismic activity and wave motion.

Like other systems already in operation, the sensors can send alerts in seconds by satellite to governments anywhere in the world. Unlike others, this system can also relay warnings directly to private subscribers over cellphones, pagers or dedicated receivers, spreading the message more widely.

Seaside hotels could install a satellite receiver to pick up warnings broadcast over the system seconds after an earthquake that could cause giant waves. Local cellphone or pager networks could do the same and send SMS messages to their subscribers.

“The sensors determine the tremor’s intensity as well as the height and speed of the waves above it,” said Gitelis, of Avtipus Patents and Inventions Ltd., which specializes in sensors and communications devices.

“The system can then analyze all the data and predict if and when a tsunami will come, where it will hit and how big its impact will be,” he told Reuters.

“We’re not doing this to make money,” Gitelis said. “He want to help people. We plan to give our product to poor countries for free and we will not charge the countries that were affected by the disaster in Asia.”

At least 145,000 people were killed in Asia by the massive Dec. 26 earthquake and the tsunamis that followed.

U.S. officials who detected the quake said they tried frantically to warn that the wall of water was coming, but there was no official alert system in the Indian Ocean because such catastrophes happen so rarely.

Tsunami warning stations exist around the Pacific Ocean.

Gitelis said his system could be particularly effective in holiday resorts like those devastated by the Indian Ocean tsunami, which took an estimated 75 minutes to reach Thailand and much longer to hit Sri Lanka and parts of India.

But in areas with poor communications it could still be hard to warn people of the approaching danger.

Samsung develops 21-inch OLED for TVs

Filed under: — Aviran Mordo

Electronics maker Samsung has unveiled a prototype OLED display that could push large screens using the next-generation technology to market sooner than expected.

The chipmaking division of the South Korean company on Tuesday announced a 21-inch display for TVs based on organic light-emitting diode technology. OLED is viewed as a potential successor to liquid crystal displays, used in many flat-panel TVs and computer monitors.

Materials in an OLED display emit light when an electrical current is applied. The displays can function without a backlight, which cuts down on power consumption, screen thickness and cost. OLED displays also offer higher resolution than LCDs.

Other electronics makers have developed and demonstrated large-screen OLED displays and smaller screens, about 2 inches across, are already being used in electric shavers, cell phones and digital cameras.

However, the Samsung announcement is noteworthy because its 21-inch prototype OLED relies on amorphous silicon technology, a mature technology used in most LCDs on the market today, according to Paul Semeza, an analyst with research firm iSuppli.

“This could lead to a quicker path to mass production because there are a lot of fabs out there that use amorphous…OLED could ride on existing investments in LCD,” he said.

Samsung is one of the top manufacturers of LCD panels.

Consumers will still have to wait years to get their hands on OLED large-screen display. According to Semenza, companies will have to improve the manufacturing process, and an industry will have to form around OLED screens.

Linksys Debut New Line of Wireless-G Products

Filed under: — Aviran Mordo

IRVINE, Calif., Jan. 4 Linksys(R), a division of Cisco Systems, Inc., and the leading global manufacturer of broadband, wireless, and networking hardware for home and Small Office/Home Office (SOHO) environments, today announced a new line of next generation Wireless-G (802.11g) products that enhance the speed and range of a Wireless-G network. The new Wireless-G Router with SRX (WRT54GX) and Wireless-G PC Card with SRX (WPC54GX) (SRX stands for Speed and Range eXpansion) can provide faster wireless network throughput, reduced dead spots, and increased wireless range over standard Wireless-G networks.

SRX is based on MIMO (Multiple In, Multiple Out) technology, a key component in the upcoming Wireless-N (802.11n) standard. MIMO uses multiple radios (2) and antennas (3) on a wireless router or client adapter for improved performance in range and speed. The Linksys Wireless-G Router with SRX and Wireless-G PC Card with SRX use this smart radio and antenna technology along with standards-based Wireless-G (802.11g) networking to provide users with faster networking throughput and a further reach of their wireless networking signal.

Users will benefit from the following features in the Linksys SRXProducts:

* Wireless network range can reach up to 3 times* farther and wireless network performance can be enhanced by up to 8 times* compared to the throughput of standard 802.11g technology when using all SRX products
* Designed for interoperability and enhanced performance with all standards-compliant 802.11g and 802.11b products
* All in one device: Internet sharing router, 4-port 10/100 switch, and an SRX-enhanced Wireless-G access point
* Includes WPA, SPI firewall and 802.1x authentication and authorization
