Fluid Power to the Rescue

Posted October 15, 2014 12:00 AM by IHS GlobalSpec eNewsletter

Researchers are using both pneumatic and hydraulic power in efforts to help patients suffering from crippling injuries. In this article, Hydraulics & Pneumatics looks at three ways fluid power could assist injured patients in getting back on their feet. One of the technologies discussed is a portable powered ankle-foot orthosis, or PPAFO, which aims to provide untethered assistance for in-home rehabilitation. The pneumatic PPAFO is powered by a bottle of compressed carbon dioxide worn on the patient's belt. The article explains how the PPAFO works and looks at the results achieved in testing the device.

Energy Storage Solution in the Bag?

Posted September 13, 2014 12:00 AM by IHS GlobalSpec eNewsletter

Can air and water combine to meet the challenge of storing energy from renewable sources? A Canadian start-up company called Hydrostor thinks so. The company's idea is to use renewable energy to produce compressed air that will be stored in large underwater bags, which could be located near offshore wind farms. When the stored energy is needed, the weight of the water forces the air back up to the surface, where it will be used to drive a turbine. A video accompanying this IEEE Spectrum piece explains how the process works.

Getting a Lift from Vacuum

Posted June 20, 2014 12:00 AM by IHS GlobalSpec eNewsletter

Aging baby boomers who lose mobility can also lose access to the upper floors of their homes. A chair lift can get the elderly and disabled upstairs, but high costs and the difficulties involved in getting in and out of the chair make this a less-than-ideal option, notes the author of this Hydraulics & Pneumatics article. His preferred alternative: a pneumatic elevator featuring a passenger cabin that's lifted by vacuum. The story explains how the technology works, why it beats conventional elevators, and why vacuum was chosen over compressed air to give the disabled a lift.

Human or Geminoid?

Posted February 17, 2014 1:00 PM by IHS GlobalSpec eNewsletter

You'll be pardoned for getting a little confused while watching a video showing so-called "Geminoids" along with the people they were modeled after. Geminoids are electromechanical devices designed to look and act like specific humans, explains this Design News piece, which includes links to several Geminoid videos. The mechanism behind Geminoid movements includes pneumatic actuators and air-flow control valves.

How Important is 'Sustainability'?

Posted December 28, 2011 12:38 PM

The American Society of Mechanical Engineers recently published the results of its third annual "sustainability" survey. Some of the respondents dismissed sustainability as a fad embraced by companies solely for its public relations value, while others expressed their support for sustainable design practices. We'd like to know where you come down. In your view, is sustainability a trivial buzzword or an important design consideration?

Are Recent Grads More Real-world Ready?

Posted November 30, 2011 9:17 AM

In a recent Design News piece about the top U.S. engineering schools, an engineer affiliated with one university on the list notes that "In the last five to 10 years, engineering curricula have shifted from theory-heavy coursework to a mixture of theory and hands-on experience." Have you noticed this shift in the workplace — i.e., do engineers right out of school seem better prepared to tackle real-world projects today than they did a decade ago?
