A robotic suit that reads brain signals and helps people with mobility problems will be available to rent in Japan for $2,200 a month starting Friday -- an invention that may have far-reaching benefits for the disabled and elderly.

HAL -- short for "hybrid assistive limb" -- is a computerized suit with sensors that read brain signals directing limb movement through the skin.

The 22-pound battery-operated computer system is belted to the waist. It captures the brain signals and relays them to mechanical leg braces strapped to the thighs and knees, which then provide robotic assistance to people as they walk.

Cyberdyne, a new company in Tsukuba outside Tokyo, will mass-produce HAL. Two people demonstrated the suits at the company's headquarters on Tuesday.

A demonstration video also showed a partially paralyzed person getting up from a chair and walking slowly wearing the HAL suit.

"We are ready to present this to the world," said Yoshiyuki Sankai, a University of Tsukuba professor who designed HAL.

Sankai, who has worked on robot suits since 1992 and is also Cyberdyne's chief executive, said a full device that covers the entire body is also being designed, though it is unclear when it will be available commercially.

HAL comes in three sizes -- small, medium and large -- and also has a one-leg version for a 150,000 yen, or $1,500, monthly rental fee.

Noel Sharkey is a robotics expert not affiliated with the technology. The professor at the University of Sheffield in the U.K. said HAL will have wide-ranging benefits for the elderly others with movement disabilities.

"HAL can only lead to extending the abilities of the elderly and keep them out of care for longer," Sharkey said in an e-mail to The Associated Press.

Cyberdyne said its policy is not to reveal how much it costs to manufacture the device. It is unclear when... Tags: design, technology, video

The latest iPhone embarrassment is a security hole that makes it simple to access stored data on supposedly locked iPhones. Apple said Thursday that a software patch to solve the problem is in the works.

An unauthorized user can exploit the security hole simply by double-pressing the button to make an emergency call. That behavior brings up the owner's preferred contacts and clicking on a number provides full access to the phone's features. Clicking on an e-mail provides access to all e-mail. And clicking on a contact name provides full access to all contacts data.

Apple spokesperson Jennifer Bowcock said, "The minor iPhone security issue which surfaced this week is fixed in a software update which will be released in September."

There is a simple workaround, Bowcock said: iPhone owners can simply change the settings so double-clicking the emergency button returns a user to the home screen, which will present a password login field if password protection is turned on.

'Design Deficiency'

While an attacker must be in physical possession of the iPhone to exploit the security bug, it "highlights a fundamental design deficiency with the iPhone," said Andrew Storms, director of security operations with nCircle Network Security.

"Despite Steve Jobs from day one saying the iPhone was secure, functionality and aesthetics of the device seem to always win out over security," Storms said. A case in point, Storms said, "Apple quickly released updates to fix 3G connectivity issues this year, but consistently takes many months to release security updates."

This particular security hole -- a simple bypass of access restrictions -- was created by Apple's preference for functionality over security, he added. "Even when a user chooses to physically secure the device with a four-digit passcode, Apple has chosen to still permit the user to use some functionality," Storms said. "By selecting to perform...

Having banned from its App Store an application that turned an iPhone 3G into a wireless modem, is Apple ready to enable just such an application itself?

That's the rumor based on an e-mail response allegedly from Apple CEO Steve Jobs to an inquiring user. The questioner forwarded the response to the Gizmodo blog, which posted the question and Jobs' purported response.

The question: Why, since AT&T offers a plan by which users can pay an extra $30 to tether their laptops to their BlackBerry, don't Apple and AT&T offer a similar plan for iPhone 3G users?

The response: "We agree, and are discussing it with ATT." The message is signed "Steve" and includes the familiar tag, "Sent from my iPhone."

E-Mail Legit?

Gizmodo thinks the response is "legitimate-looking," but concedes "that 'Sent from my iPhone' kicker either makes this e-mail completely legitimate or illegitimate." On the other hand, Wired News engaged in a little grammatical sleuthing, noting that a message, purportedly from Jobs, posted on the MacRumors site contained a similar construction.

"We are working on some bugs which affect around two percent of the iPhones shipped, and hope to have a software update soon," the message read. Wired points out that both messages incorrectly use a comma before the "and." (A comma is appropriate to separate independent clauses; in both cases the phrases after the comma are dependent clauses.)

"I don't mean to draw a conclusion based on this nitpicky observation, but I just thought it'd be interesting to point out," Wired writer Brian Chen pointed out.

AT&T Terms of Service

Any tethering application would require a change to AT&T's terms of service. Those terms state: "Furthermore, plans (unless specifically designated for tethering usage) cannot be used for any applications that tether the device (through use of, including without limitation, connection kits, other phone/PDA-to-computer...
