Tree harvesting design that is forest-friendly

A German mechanical engineer has designed a tree harvester that weighs just over a tenth of conventional vehicles used to fell trees, which causes less damage to forest floor. Industrial tree harvesting vehicles can weigh up to 55 tons. In comparison, the “Striding Harvester” weighs only 7.5 tons. The concept harvester by mechanical engineer and industrial designer Christian Knobloch works by using a small footprint selectively pushing down on the soil as it moves. Through this approach the soil is allowed to recover much faster than if conventional heavy forest equipment was employed. Read More

Ossur rolls-out next generation POWER KNEE

Earlier this week we looked at developments in low-cost prosthetics, but at the other end of the spectrum, advanced prosthetic devices like Ossur's recently announced second generation POWER KNEE are opening up new frontiers in the field. As the world’s first motor-powered artificially intelligent prosthesis for above the knee amputees, the POWER KNEE is designed to enable daily activities without having to think about movement. Something most of us take for granted. Read More

The Carl Gustav Recoilless Rifle - 60 years and still going strong

In the world of military technology, new weapon capabilities quickly supersede the old. With the United States expenditure for the 2009 fiscal year at US$515.4 billion, it's rare to find a very old weapon still cutting it with the best on the battlefield, but the Carl Gustav recoilless rifle (CG) has proved the exception to this rule. First produced in 1946, the Carl Gustav remains in widespread use today. Read More

A $20 prosthetic knee to bring relief to disadvantaged amputees

An artificial knee costing just USD$20 promises to deliver much needed help to amputees who are disadvantaged or impoverished – particularly when the price of high-end titanium knee joints can range anywhere from USD$10,000 to USD$100,000. The artificial knee, dubbed the JaipurKnee, was developed by Joel Sadler, a lecturer in mechanical engineering and d'Arbeloff Fellow, and his team at the Hasso Plattner Institute of Design at Stanford University.

ONR demonstrates new counter-mine cloaking technology

Naval mine strikes are cited as the root cause of almost 4/5ths of U.S. Navy ship casualties occurring since 1950, so any device that either detects mines or cloaks the ship to avoid detonation will aid in the reduction of these alarming statistics. This new technology developed by the Office of Naval Research (ONR) consists of a high temperature superconducting (HTS) degaussing coil which acts to form a cloaking device which eliminates the magnetic signature of the ship. This interferes with undersea mines' ability to detect and detonate when a large magnetic field – like the one created by a ship – comes within close proximity. Read More
