Access to Wireless Towers

LANSING, Mich. -- Gov. Jennifer Granholm issued an order in mid-April that will allow local law enforcement agencies to mount their own radio communications equipment on 181 radio towers around the state for Michigan's Public Safety Communications System (MPSCS).

"These days, when homeland security and emergency management are among our country's first priorities, coordination, cooperation and communication are key," Granholm said. "It is critical that local law enforcement agencies communicate effectively with other first responders, particularly the Michigan State Police."

The governor's order, Executive Directive 2003-12, instructs state department directors and agency heads to permit any governmental public safety agency to install public safety communications equipment on the MPSCS towers as long as the equipment is compatible with the state's equipment, according to the Governor's Office.

Any installation, operation, maintenance and removal costs associated with local law enforcement equipment will be paid for by the local governmental entity, the Governor's Office said.

"The reliable, clear and complete communication services provided by MPSCS are essential in providing law enforcement and emergency personnel with fast and accurate information," Granholm said.

Since 1994, Michigan has invested more than $200 million to create MPSCS -- a communications system for law enforcement and emergency personnel that allows Michigan State Police troopers and other government officials to talk to each other from anywhere in the state.

Intel Researchers Teach Computers to Read Lips

BERLIN -- Intel researchers released software under an open source license that allows developers to build computers that read lips the way humans do.

Combined with face detection algorithms from Intel's OpenCV computer vision library, the new audio-visual speech recognition (AVSR) software allows computers to watch a speaker's face and track movements of the speaker's mouth. Synchronizing video data with speech identification makes for much more accurate speech recognition and enhances a wide variety of computer applications in noisy environments, according to researchers.

The AVSR software is part of Intel's OpenCV computer vision library, a toolbox of more than 500 imaging functions that helps researchers develop computer vision applications.

"Intel wants to develop technology that allows computers to naturally interact with the world the way humans do," said Justin Rattner, a senior fellow in the company's Enterprise Platform Group and director of Intel's Microprocessor Research Labs. "Human recognition is seldom based on a single type of information. We make decisions by combining information from a variety of sources."

Faster microprocessors, falling camera prices and 10 times more video capture bandwidth from technologies like USB2 all help real-time computer vision algorithms run better on mainstream PCs.

OpenCV is designed to increase innovation in this field by providing source code for a wide range of computer vision and imaging functions, according to Intel. Since its release in 2000, OpenCV code downloads surpassed 500,000, and it has attracted more than 5,000 registered members to its user group.

Braille PDA Released

ARNHEM, The Netherlands -- Combining an accessible GSM cell phone, mobile Internet services and note-taking functionality, the mobile phone organizer (MPO) is the first personal wireless device of its kind for visually impaired individuals.

The MPO is a compact, all-in-one device that allows users to make phone calls, send SMS messages, look up information and take notes. The MPO operates for about one day on rechargeable batteries -- depending on functionality and output medium -- and can be linked to a PC to exchange data.

For visually impaired users, all functions -- including menus, contact information, SMS messages, services and system information -- are accessible in Braille and speech. The MPO offers an eight-key Braille keyboard
