LAS VEGAS--Lexus showed off a prototype version of its safety-focused research vehicle today at CES, and it's designed to be more aware of what's going on around on the road.

That translates to a car that's been equipped with a bevy of sensors and other technological goodies, including a roof-mounted Light Detection and Ranging (LIDAR) laser that can detect objects from 70 feet away.

Other additions include a trio of hi-def cameras that look out for nearby vehicles; a sensor that detects the car's speed and angle; and a GPS antenna that Lexus says can figure out which way your car is pointed even when the car isn't moving. … Read more

This is how you sell tech gear:

Yesterday I walked into B&H Photo in New York, which claims to be the country's largest non-chain camera store, and asked one of the many sales representatives if he was an expert on tripods. He smiled and responded: "It's a ball and three legs so you really don't need to be an expert."

I told him I needed to upgrade my tripod and he showed me how to get more life out of my old one. A few weeks ago, a B&H sales person … Read more

VP9, the successor to Google's VP8 video compression technology at the center of a techno-political controversy, has made its first appearance outside Google's walls.

Google has built VP9 support into Chrome, though only in an early-stage version of the browser for developers. In another change, it also added support for the new Opus audio compression technology that's got the potential to improve voice communications and music streaming on the Internet.

VP9 and Opus are codecs, technology used to encode streams of data into compressed form then decode them later, enabling efficient use of limited network or storage … Read more

Microsoft and Motorola aren't even close to agreeing on how much the software giant should pay for the right to use patents held by its Google-owned rival.

In court filings released yesterday and obtained by Reuters, Microsoft indicated that it would be willing to pay as much as $502,000 per year to license Motorola's H.264 video patents. The company would also pay as much as $736,000 for Motorola's 802.11 wireless technology.

Motorola, meanwhile, insists that a simple fee isn't enough -- it wants Microsoft to pay a percentage of its revenues derived … Read more

A Ph.D. student at the University of Toronto is using the same transfer paper currently affixing temporary tattoos to kids -- in conjunction with a common screen-printing technique -- to develop a medical sensor that keeps tabs on a person's exertion by monitoring the skin's pH levels.

Similar devices, which are called ion-selective electrodes (ISEs), are already common among athletic trainers and medical researchers to help spot fatigue, dehydration, or even metabolic diseases. But they tend to be bulky and don't stick well to sweaty skin.

The new sensor stays put and doesn't look so, … Read more

Microsoft has won an important ruling in its patent battle with Motorola.

U.S. District Court Judge James Robart last week ruled that Motorola could not ban the sale of Microsoft products that the mobile maker alleges violate its H.264 patents. The ruling means that the Xbox and Windows, along with other Microsoft products, won't be banned from sale in the U.S. The ruling also blocks Motorola from banning Microsoft product sales in Germany.

Computerworld previously reported on the ruling.

Microsoft and Motorola are embroiled in a legal spat around the world over the software giant's … Read more

Technology topics can mark a rare bipartisan area of political agreement: Both Mitt Romney and Barack Obama say they would make cybersecurity a priority, and both like to talk up government funding of basic research.

If you look a bit more closely, however, differences emerge. They're perhaps most marked over federal regulation, where the two major parties have long-standing disagreements, but also exist on topics like WikiLeaks, copyright legislation, and whether to levy a new tax on broadband providers.

Canon plans to release a notable firmware update to its high-end EOS 5D Mark III in April that will let videographers use the SLR to record uncompressed HDMI video.

As the successor to the 5D Mark II that jump-started the video SLR revolution four years ago, the 22-megapixel 5D3 has big shoes to fill. The new update surely will help professionals who need better quality, even if ordinary folks need not care much. Here's what Canon had to say about the news:

When shooting video, HDMI Output makes possible the recording of high-definition uncompressed video data (YCbCr 4:2:… Read more
