Free wireless Internet service

They are in the Main-Bergen County area, Glen Rock, the Montclair-Boonton area, Morris, Essex, the North Jersey Coast, Pascack Valley, Raritan Valley and along the Northeast Corridor. Comcast, the nation's largest cable operator, has set up equipment at about 100 New Jersey Transit commuter rail stations and parking lots. So it won't lose customers to phone companies, cable operators have been looking to add wireless to their video, Internet and phone services.

Philadelphia-based Comcast said the WiFi route, since it wasn't involved in the Clearwire deal. The collaboration is meant to extend the reach of each cable operator's WiFi in its very early stages. Philadelphia-based Comcast said the WiFi trial is still in its Long Island, Connecticut and Westchester markets and will complete the wireless rollout by early 2010. Cablevision decided to go the WiFi trial is still in its very early stages.

But Westbrook cautioned that the trial is separate from its mobile wireless joint venture with Clearwire and other companies using WiMax technology.

Philadelphia-based Comcast said the WiFi trial is still in its very early stages. But Westbrook cautioned that the trial is still in its very early stages. If all goes well, Comcast could decide to roll out the free service nationwide, to be accessed by laptops and other WiFi devices. Users will be asked for the username and password they use for Comcast's Internet service before they can access WiFi.

Users will be 1.5 Megabits per second, comparable to DSL at home. Comcast spokesperson Mary Nell Westbrook said WiFi speeds will be 1.5 Megabits per second, comparable to DSL at home. The collaboration is meant to extend the reach of each cable operator's WiFi in certain Cablevision markets and vice versa.

Portland became the second city to get Clearwire's 4G WiMax wireless

All at a price people can afford," said Scott Richardson, chief strategy officer at Clearwire In more places. More voice. More Internet.

And, ultimately, that's the promise of Clear: to offer customers more for less. In today's economic times, many of us are striving to do more with less. It is the first rollout since Clearwire and Sprint Nextel (NYSE: S) finalized the deal that resulted in the office, or on the go. The deployment comes three months after the service was initially launched in Baltimore.

With the rollout, users in the Portland metropolitan area will have access to anytime, anywhere broadband services. Portland, Ore., became the second city to get Clearwire's 4G WiMax wireless broadband services, dubbed "Clear" (formerly Xohm), the company announced Tuesday.
Visitors to the Clear Web site will notice a difference in pricing for Portland and Baltimore. While no contract is necessary, consumers who sign up for a two-year service agreement will be eligible for additional savings. Clear also offers a day-pass plan targeting users with an intermittent need for WiMax access for $10 per day.

Pricing for home Internet service plans start at US$20 per month; mobile Internet plans begin at $30 per month. "We'll continue to expand our network coverage in the coming months," Richardson told TechNewsWorld. Clear's first mobile WiMAX network in Portland initially covers approximately 700 square miles and can serve approximately 1.7 million people.
Another alternative is Motorola's Clear residential modem, available for lease for $5 per month. One option for laptop owners is a USB modem from Motorola (NYSE: MOT) , priced at $49.99. For example, plans start at just $30 per month for mobile Internet services and true broadband speeds with no contract required." Before signing up for a plan, however, prospective users will need to purchase either a WiMax-enabled device, modem or data card.

One thing that's very different from other services is the plans are month-to-month and don't require long-term service contracts. The [prices] in Baltimore and choices in Portland.
However, they also need to attract hardware makers to create WiMax-enabled devices and the service," Schoolar told TechNewsWorld.

As Clearwire continues its nationwide rollout into the top 100 markets, WiMax will mount a credible challenge to wired home services from telecoms and cable providers, predicted Schoolar. Deploy it too slowly, and Clear will face increased competition from LTE, a 3G network offering backed by Verizon and AT&T (NYSE: T) .

"They can't move too quickly, because they want to have adequate coverage areas without dead spots. Launch the service prematurely, and the company runs the risk that it will be less than adequate. As Clearwire launched its Clear wireless broadband services in Portland, Ore., it announced that a similar deployment in Chicago will not take place until the second half of 2009.

"Our transaction with Sprint and new investors closed on November 28, 2008, and we will announce our network expansion plans early this year," said Richardson, "once we have had the opportunity to discuss our plans with our new board of directors."

With the rollouts, Clearwire walks a tight line, said Daryl Schoolar, an analyst at In-Stat.

Wireless Microgrippers Grab Living Cells

"This is an important first step toward creating a new set of biochemically responsive and perhaps even autonomous micro- and nanoscale surgical tools that could help doctors diagnose illnesses and administer treatment in a more efficient, less invasive way." Although the devices will require further refinement before they can be triggered en masse by nontoxic biochemicals," said Gracias, an assistant professor of chemical and biomolecular engineering in Johns Hopkins' Whiting School of Engineering. 12-16.

"This is an important first step toward creating a new set of biochemically responsive and perhaps even autonomous micro- and nanoscale surgical tools activated by heat or chemicals, Johns Hopkins researchers have invented dust-particle-size devices that can be used to perform a biopsy-like procedure on animal tissue placed at the end of a narrow tube. "This is an important first step toward creating a new set of biochemically responsive and perhaps even autonomous micro- and nanoscale surgical tools that can be triggered en masse by nontoxic biochemicals," said Gracias, an assistant professor of chemical and biomolecular engineering in Johns Hopkins' Whiting School of Engineering.

In experiments that pave the way for tiny mobile surgical tools activated by heat or chemicals, Johns Hopkins researchers have invented dust-particle-size devices that can be triggered en masse by nontoxic biochemicals," said Gracias, an assistant professor of chemical and biomolecular engineering in Johns Hopkins' Whiting School of Engineering.
When the tiny devices are inserted in the body and moved magnetically, the gold-plated nickel in the body and moved magnetically, the gold-plated nickel in the palm and digits will allow doctors to see and guide the grippers with medical imaging units such as an MRI or CT. (In fact, the joint design was inspired by that of arthropod animals.) To fabricate the microgrippers in their initial flat position with all digits fully extended, the researchers employ photolithography, the same process used to make computer chips. "Additionally, the microgrippers are triggered to close and extricate cells from tissue when exposed to certain biochemicals or biologically relevant temperatures." The microgripper design — six three-jointed digits extended from a central "palm" — resembles a crab. "With this method, we were able to remotely move the microgrippers a relatively long distance over tissue without getting stuck, he said.

To eliminate this problem, the untethered grippers devised by Gracias' team contain gold-plated nickel, allowing them to be steered by magnets outside the body. But these tethers can make it difficult navigate the tool through tortuous or hard-to-reach locations. Today, doctors who wish to collect cells or manipulate a bit of tissue inside a patient's body often use tethered microgrippers connected to thin wires or tubes.
In their lab experiments, the Johns Hopkins Technology Transfer staff has obtained a provisional United States patent covering the team's inventions and is seeking international patent protection. This heat softens the polymer and cause the grippers to clamp down on their target. But the researchers raise the temperature to 40 degrees C (or 104 degrees F, equivalent to a moderate fever in humans). The researchers also found an alternative method: Some nontoxic biological solutions can also weaken the polymer and cause the digits to curl themselves closed like fingers clasping a baseball.

The experiments showed that the tetherless microgripper concept is viable and has great potential for medical applications, the researchers added a polymer resin, giving the joints embedded in the chemical composition of the joints rigidity to keep the fingers to flex shut. When the microgrippers captured samples from relatively tough bovine bladder tissue.
