World-class wind tunnel opens in Williston

The world’s largest wind tunnel for wind sensor calibration opened in Williston – and Governor Peter Shumlin and representatives from The University of Vermont (UVM) and NRG Systems were on hand for the event. Owned and operated by Svend Ole Hansen of SOH Wind Engineering, this facility will be used to calibrate wind sensors like those manufactured by Hinesburg’s NRG Systems as well as to test the effects of wind on large structures like bridges and buildings. The wind tunnel will also serve as an educational resource for the UVMstudents.

“The opening of this wind tunnel is great news for Vermont,” said Governor Peter Shumlin. “Not only will it help support businesses like NRG Systems that require this specialized service, the wind tunnel provides a great learning opportunity for our science, technology, engineering and math students.”

Svend Ole Hansen, principal of SOH Wind Engineering and wind tunnel owner, decided to launch this new business in the United States in response to a request issued by Hinesburg-based NRG Systems, global manufacturer of wind turbine measurement equipment and optimization systems.

“The reason I chose to site my business in Vermont is because of NRG Systems,” said Svend Ole Hansen. “And the reason we’ve constructed such a large tunnel is it will allow my company to advance the science of wind engineering and gain a better understanding of wind forces on a variety of structures.”

“The presence of this new wind tunnel is great news for our company, our customers, and the global wind industry in general,” said John Norton, chief operating officer of NRG Systems. “It creates the opportunity to understand the behavior of our sensors in an unrestricted but controlled environment and it allows NRG Systems to verify the accuracy of sensor calibrations, reduce transportation costs, and better serve our customers.”

The wind tunnel will also serve as an educational resource for UVM professors and students in the engineering school. Currently, two UVM engineering students are working at the facility and others are using the facility for academic projects.

“We are so fortunate to have a facility of this caliber in our backyard,” said Dryver Huston, PhD, UVM’s College of Engineering and Mathematical Sciences. “This gives our students the opportunity to apply what they learn in the classroom into a real world setting.”

The wind tunnel facility has a wide range of applications for businesses in civil and mechanical engineering, architecture, transportation and renewable energy. Its flexible design allows it to be configured to test large structures such as bridges and buildings as well as small items such as anemometers. At full build-out the Williston facility will operate four closed return-flow wind tunnels; two of which are operating now. Each wind tunnel measures about 10 feet tall by 10 feet wide and 125 feet long and includes two 125 horsepower fans capable of producing wind speeds up to 65 miles per hour.

Launching the business was a two-year initiative that integrated private investment with public dollars. Based on the capital investment and employment projections, SOH secured a grant under The Vermont Economic Growth Initiative for roughly $150,000.

SOH Wind Engineering is an independently-owned company that is located in Williston, Vermont. Together with its sister company, Svend Ole Hansen ApS, located in Copenhagen, Denmark, the company has more than 25 years of experience in wind engineering and boundary layer wind tunnel testing.


Cutting-edge cancer robot for WA

WA will be the first Australian State with a revolutionary cancer treatment that uses highly targeted radiation on tumours once considered untreatable.

The robotic machine, known as CyberKnife and costing $9 million, will be installed at the State Comprehensive Cancer Centre at Sir Charles Gairdner Hospital.

An Australian physicist developed the technology about 20 years ago and it has been used in 300 centres worldwide, including in the US, Europe and Asia.

But it has never been available in Australia, prompting some people to pay up to $100,000 to have the treatment overseas.

Despite its name, CyberKnife is not a knife but fires beams of radiation at a tumour from virtually any direction via a robotic arm, without affecting healthy tissue.

The tracking software detects any movement of the tumour or patient and automatically corrects the robot position before targeting the tumour with multiple beams of high-energy radiation.

The treatment is so accurate, it can treat tumours previously seen as inoperable or untreatable.

Because it gives significantly more targeted radiation, it is 100 times more potent and treats patients much faster, with most only needing three to five visits compared with up to 50 with existing radiation treatment.

Professor David Joseph, head of radiation oncology at SCGH, said he had lobbied for 10 years to get the technology in WA.

“This is a very exciting development for the people of WA and will revolutionise radiation treatment by allowing us to use a pencil beam to deliver incredibly precise radiation to the body,” he said.

“For prostate cancer, for example, it will mean much less toxic treatment that can be given in a much shorter time.”

The CyberKnife can treat many cancers including in the lungs, head, neck, spine, abdomen and prostate. In WA, it will initially be used on head and neck cancers.

A full-service Longmont, Boulder, and Denver area CNC machine shop, is pleased to announce today the acquisition of a new precision coordinate measuring machine (CMM), adding to its increasing inventory of cutting-edge CNC machining tools. Owing to the recent upswing in the manufacturing sector, Colorado based APM has experienced steady growth since beginning operations in 2005, allowing for recent expansion.

Cynosure Receives FDA Clearance for PicoSure

Cynosure, Inc. CYNO +10.69% a leader in laser- and light-based treatments for minimally invasive and non-invasive aesthetic applications, today announced that it has received FDA 510(k) clearance to market the PicoSure(TM) laser workstation for the removal of tattoos and benign pigmented lesions. The Company expects to sell PicoSure initially through its U.S. direct sales force to aesthetic dermatologists and plastic surgeons beginning in early 2013.

“FDA clearance of PicoSure is a major milestone that caps nearly a decade of research and development at Cynosure to commercialize the world’s first safe and effective picosecond aesthetic laser specifically designed for the removal of tattoos and benign pigmented lesions,” said President and CEO Michael Davin. “PicoSure accomplishes this by delivering short-pulse bursts of energy to the skin in trillionths of a second. With data indicating that an estimated 20 percent of the 45 million Americans with at least one tattoo want to have it removed, the FDA clearance of PicoSure creates a first-mover advantage for Cynosure to treat a large and vastly underserved market.”

Roy Geronemus, M.D., Director of the Laser & Skin Surgery Center of New York, performed a study in which 22 subjects with multicolored and recalcitrant tattoos were treated with PicoSure over a two-week period. The results demonstrated greater than 80% overall tattoo clearance. On average, 94% clearance was achieved for blue and green ink.

“The picosecond laser’s shorter pulse duration erases tattoo pigment more efficiently, leading to a higher level of patient satisfaction and improved results compared with current nanosecond technology,” Dr. Geronemus said. “Our study shows that picosecond technology more effectively targets blue and green pigment, which is typically difficult to remove. In addition, PicoSure more rapidly lightens other colors, with improved recovery time due to less collateral injury to the surrounding tissue.”

Boston dermatologists Kenneth A. Arndt, M.D. and Jeffrey Dover, M.D., Directors of SkinCare Physicians in Chestnut Hill, Massachusetts, called PicoSure “the most dramatic improvement in the treatment of tattoos and pigmented lesions in more than two decades” and said they expected the product to rapidly become the “first-in-class treatment” for these indications.

A study led by Drs. Arndt and Dover focused on demonstrating that treatment with a picosecond laser improved clearance of benign pigmented lesions and tattoos with reduced side effects and fewer treatments than other lasers. A total of 15 subjects with tattoos and five subjects with benign pigmented lesions were enrolled in the study. Follow-up was conducted at one month and three months after the last treatment. The study found that 100% of the pigmented lesions were cleared by two treatments, and that tattoo clearance of greater than 75% was achieved in 75% of patients within three to four treatments.

“PicoSure delivers photothermal and significant photomechanical effects to the tattoo or pigmented lesion while leaving the surrounding tissue unheated,” Dr. Arndt said. “The speed of the picosecond laser makes this technology ideal for aesthetic applications in which large photomechanical stresses are applied to a particular target.”

Davin concluded, “Our multi-year investment in PicoSure reflects our commitment to innovate and develop industry-leading technology. We continue to build a broad intellectual property portfolio targeting a range of high-volume aesthetic applications.”
