Can you imagine placing your cellphone on a Starbucks table and seeing it charge instantly?

Gainesville, Fla.-based WiPower (pronounced "y"-power) is manufacturing wireless-charging technology that could potentially facilitate just that.

Ryan Tseng founded WiPower after he realized how burdening it is to travel with bundles of chargers.

His frustration resulted in WiPower's wireless power transmitter, a mouse pad-like device that connects to a wall with one cord. Devices with an integrated power receiver placed upon the mat start charging immediately.

The product uses inductive coupling, a technology electric toothbrushes have used for years now, mostly because it shields their components from water. Earlier this year, Palm introduced its Touchstone charger, which uses this technology.

WiPower's charging mat simultaneously powers multiple devices in any position with different power requirements. For example, a digital camera requires much more power than an iPod Shuffle, but both can be charged with a WiPower.

DUBLIN, Calif.--Don't tase me, bro. Really.

CNET News took a trip to the Alameda County Sheriff's Office Regional Training Center on Friday to have a look at some of the newest equipment from Taser, which was among the companies showing off weaponry at the UrbanShield 2009 training event. The electric-shock gadgets are controversial and have drummed up some bad press over the years for causing the occasional serious injury or even fatality. But the company has maintained its insistence that they are significantly safer than the alternative (i.e. guns).

We didn't get to tase anybody. But we did get to see the Shockwave, a big Taser device that can incapacitate five or six people at a time, which company representatives told us is designed for crowd-control situations and can be ... Read more

The Defense Advanced Research Projects Agency has demoed its Precision Urban Hopper robot, a wheeled ground unit that can leap over 25-foot-tall obstacles and keep on truckin'.

Seen in the video below, released last week by the Sandia National Laboratory, the shoebox-size Hopper easily takes on a chain-link fence, bounces a bit after landing, and then keeps rolling. It seems that a piston-fired leg makes it fly.

The Precision Urban Hopper is being developed by Sandia and Boston Dynamics, creator of the famously creepy BigDog robot, for surveillance operations in urban terrain. Guided by GPS, it is designed to "bolster the capabilities of troops and special forces engaged in urban combat," navigating autonomously, according to Jon Salton, a program manager at Sandia.

Sandia said hopping has "shown to be five times more fuel-efficient than hovering," when it comes to getting around obstacles less than 30 feet tall. It added that other potential applications of

We're proud to announce the debut of CNET LIVE, the new portal for all live shows, including The 404, on CNET. Don't worry, the transition won't be as difficult as DTV. We'll give you detailed instructions on how to tell all your friends about the show! Listen in for all the juicy details on our weekend staycation and why Wilson should never consume liquor again.

Atlantic City: What a dump!

So now that the weekend is over, we can talk about our top secret trip...to Atlantic City! It's always good to get away for a little bit, even if it's just for a day, so we packed up our bags and took off to AC for a little gambling and good times. What was supposed to be a relaxing trip turned out to be 24 hours of "The Hangover"-esque partying. We all indulged in our own vices: Jeff hit the blackjack tables like a white bat out of hell, Justin explored the dark crevices of AC's back alleys, and Wilson Tang ate chicken. That's right, you read it correctly: Wilson Tang finally broke his "vegetarianism" and is now an official chicken chaser. Unfortunately, his bout with poultry at Friday's dinner left him with a mad stomach ache and he party pooped his way out of the trip. What a shrew!

Lots of stories to talk about today, namely two big news items from over the weekend: the DTV official transition and the mad rush for Facebook Vanity URLs. Actually, the long-awaited DTV transition went off without a hitch, which makes sense, because it's been in the works forever now, although we're pretty sure someone in Florida tried to eat her converter box. Facebook Vanity also had little to no effect on real life, although there did seem to be a slight flux in traffic on Thursday night as people rushed to reserve their own Facebook URLs. In the spirit of American sportsmanship, some of the landgrabs were a little disingenuous; for example, check out the profile for our own Molly Wood. In fact, my own name got snaked by another Justin Yu, so feel free to add him and let him know how much you love The 404. In the meantime, check out the Facebook profiles for the Real Justin Yu, Wilson Tang, and Jeff Bakalar.

The last 20 years of gaming have treated us to better graphics and sound, more innovative control schemes, and more mature and sophisticated storylines. Could the next innovation involve the olfactory system? If the team behind some unique British Army training videos have anything to say about it, then yes.

According to a Daily Mail article, researchers in the U.K. have partnered with the Ministry of Defence there to make training videos for the British Army a tad more immersive. While the troops watch the videos, foul smells are released into the air, appropriate to what's onscreen.

"Yes, two Raw Sewages and a Weapon Fire please."

For example, a training video involving a real-life village would have the smell of cooking food associated with it, teaching the soldier to associate that village or type of village with that smell.

Then, when the soldier enters the village in real life, the absence of such a smell could signify that the area had been evacuated and taken over by hostile forces. Or that no one was cooking at that time.

Professor Bob Stone, an engineering professor and research director of the Human Factors Integration Defence Technology Centre (HFIDTC, or SHIELD) at Birmingham University, says the scent delivery system, or SDS100, consists of a compressed air chamber with eight compartments and four fans. Each compartment holds a pot of wax, chemically infused with a particular odor.

With 100 scent options available, including "weapon fire," "cat urine," and "human feces," it's no wonder the researchers speculate that this technology could be incorporated into video games "within three to five years" ('cause gamers just love the smell of cat urine).

The U.S. military has found the iPod Touch to be a valuable battlefield tool for soldiers.

Updated at 1:25 p.m. PDT to clarify that apps being developed for iPhone as well.

The hottest new battlefield weapon in Baghdad is also a hot item on the home front.

Apple's iPod Touch is proving to be a valuable tool to members of the U.S. military, according to a report in Newsweek.

The report notes that the iPod performs many functions in this time of "networked warfare," enabling soldiers to be linked with other soldiers, as well as intelligence resources, such as aerial images from drones and translation software.

Soldiers can use applications to add translated phrases to maps and photos, as well as show villagers video messages from local leaders. A new program called Vcommunicator translates spoken and written Arabic, Kurdish, as well as two Afghan languages.

Another application developed for the iPhone allows soldiers to take a photo of a street sign, upload it, and immediately receive intelligence on ... Read more

The U.S. Army has committed to renewing its partnership and providing another $50 million to Arizona State University's flexible-display research facility, the university announced on Thursday.

That brings the Army's total investment since the Flexible Display Center (FDC) started in 2004 to $100 million.

The announcement comes in conjunction with a two-day event in Tempe, Ariz., near ASU, in which the U.S. Army and Flexible Display Center plan to showcase their progress to the public.

So why is the military so keen on flexible displays?

It's all about information and communications...and possibly profit.

A mock-up of a roll-out electronic map provides just one creative example of how flexible displays might be useful to the U.S. Army.

Flexible displays are paper-thin electronic screens that can be bent, mounted onto objects, and sewn into clothing. Soldiers could easily wear them on their sleeves or wrists, and use them to receive critical data in real time in the form of instructions, photos, or maps.

In addition, flexible displays can be made more durable than regular LCD screens, allowing them to get banged around in combat and still work. They also consume only a fraction of the power of LCDs.

That doesn't just make them good for the military; it also makes for cool tech products.

That commercial value is something the military, ASU, and its partners clearly have in mind.

A prototype high-tech cuff that detects and treats bleeding from combat injuries got a step closer to the battlefield Monday when Siemens Healthcare announced an exclusive contract with the Defense Advance Research Projects Agency to develop the device.

The Deep Bleeder Acoustic Coagulation cuff, or DBAC, is designed to limit blood loss from penetrating wounds to limbs--as in the case of a gunshot injury--thus reducing the risk of limb loss or death.

Once the cuff is applied, ultrasound technology within the device automatically would identify the location and severity of the bleeding. This in turn would trigger therapeutic ultrasound elements to emit and focus high-power energy toward the bleeding sites, speeding coagulation and halting bleeding.

Siemens says the compact and lightweight device can accommodate a variety of limb sizes, from a wide male thigh to a narrow female arm. The cuff is intended to shut off automatically and to be ... Read more

The U.S. Army plans to spend up to $200 million on iRobot products over the next five years, iRobot announced Tuesday.

The contract iRobot previously had with the U.S. Army Program Executive Office for Simulation, Training, and Instrumentation expired in May 2008 and was limited to the purchase of PackBots.

The new contract gives the U.S. Army the freedom to purchase parts, training, and maintenance services from iRobot, as well as any robots from the company's industrial or consumer lines over the next five years, according to iRobot.

However, the $200 million five-year contract that was awarded is a "ceiling priced Indefinite-Delivery/Indefinite-Quantity (IDIQ) contract," iRobot said in a statement.

That means the U.S. Army may or may not spend the full $200 million in products promised.

IDIQ contracts are common between vendors and U.S. government agencies because they are flexible and unrestricted.

According to Federal Acquisition Regulation on IDIQ contracts, the U.S. government does not have ... Read more
