Today, at the TCT 2007 Conference in Coventry, Creaform unveiled their new scanner, the EXAScan. This scanner comes in to expand the Handyscan3d product line, along with the existing REVScan.

According to Creaform, the EXAScan is able to achieve resolutions 5 times greater and precisions 2 times better than the existing REVScan. It will also feature automatic multi-resolution. The user will be able to acquire data in higher resolution and it will be seamlessly integrated with the rest of the surface. This is especially nice since the scanner directly yields the surface and does not rely on an point cloud to structure its 3D data.

As with the REVScan, the EXAScan will be self-positioned: there is no need for a positioning device such as an arm or a CMM. This system makes it possible to move the scanner and the scanned piece independently and thus acquire the piece in its entierty.

Since it is based on the REVScan, it retains all of its advantages:

• Handheld
• Highly portable
• Automatic surface generation
• Easy to use and to learn

The EXAScan is a highly versatile tool that can be used in many application domains, such as aerospace and aeoronautics, medical, multimedia and much more.

Creaform expects to ship the first units in 6 to 8 weeks from now, but is already taking orders for the scanner. It will be priced around 50,000 US$, which is pretty affordable for such a system. You can read the original press release on the HandyScan3d website.wife needs a bare ass spanking

American Press, Tupoka, KA – The Kansas state Board of Education on Tuesday repealed science guidelines questioning evolution that had made the state an object of ridicule.

The new guidelines reflect mainstream scientific views of evolution and represent a political defeat for advocates of “intelligent design,” who had helped write the standards that are being jettisoned.

The intelligent design concept holds that life is so complex that it must have been created by a higher authority.

The state has had five sets of standards in eight years, with anti- and pro-evolution versions, each doomed by the seesawing fortunes of socially conservative Republicans and a coalition of Democrats and moderate Republicans.

The board on Tuesday removed language suggesting that key evolutionary concepts — such as a common origin for all life on Earth and change in species creating new ones — were controversial and being challenged by new research. Also approved was a new definition of science, specifically limiting it to the search for natural explanations of what is observed in the universe.

“Those standards represent mainstream scientific consensus about both what science is and what evolution is,” said Jack Krebs, a math and technology teacher who helped write the new guidelines. He is also president of Kansas Citizens for Science.

The state uses its standards to develop tests that measure how well students are learning science. Although decisions about what is taught in classrooms remain with 296 local school boards, both sides in the evolution dispute say the standards will influence teachers as they try to ensure that their students test well.

John Calvert, a retired attorney who helped found the Intelligent Design Network, said under the new standards, “students will be fed an answer which may be right or wrong” about questions like the origin of life.

“Who does that model put first?” he said. “The student, or those supplying the preordained ‘natural explanation’?”

The Board of Education’s swing back wasn’t likely to settle the issue, given many Kansans’ religious objections and other misgivings about evolution.

“I don’t think this issue is going to go away. I think it’s going to be around forever,” board chairman Bill Wagnon, a Topeka Democrat who supports evolution-friendly standards, said before the vote.

“There’s this, I think, political agenda to just ensure that evolution is the driving, underlying notion that has to be accepted in Kansas science standards in order for Kansas to keep its head up in the world, which is just bizarre,” said board member Ken Willard, a Republican who supported the 2005 standards.
