Medical technology has undergone some of the most revolutionary changes of any field in the Twentieth Century. And while many of the advances have included drugs, many more have involved the technology physicians use to diagnose and treat illness. Several winners of the Design News Engineer of the Year award have won for the medical-device breakthroughs they have brought about, including Rowland Redington (MRIs), Terry Haber (safe needles), Victor Poirier (left ventricular heart device), Dean Kamen (infusion pumps for dispensing drugs), and our most recent winner, Lynn Otten, who developed the first device to receive FDA approval for long-term implant in the brain. It controls essential tremors from Parkinson's Disease.
Here are some of the other medical breakthroughs of the century:
The first practical electrocardiograph, invented by Willem Einthoven in 1900.
The first X-ray patent, awarded to William Coolidge in 1917.
The electroencephalograph, 1929.
The first artificial kidney for humans, 1943.
The heart-lung machine, 1953.
The cardiac pacemaker, invented by Wilson Greatbach, 1958.
The laser, which enables present-day applications such as non-invasive retina surgery, cauterization of stomach ulcers, and the clearing away of cholesterol blockages of arteries.
Functional neuromuscular stimulation, 1961.
Fiberoptic endoscopes, to enable physicians to visually examine body cavities and hollow organs without invasive surgery, 1968.
Positron Emission Tomography, 1970.
Computer Axial Tomography, 1970.
Magnetic Resonance Imaging, 1979.
Lithotripsy, the ultrasonic technique for crushing kidney stones.
Functional Electrical Stimulation for grasp-and-release motor prosthesis.
The Jarvik artificial heart, 1982.
Cochlear implants, 1983.
The Parastep motor prosthesis system for limb control, 1995.
And many more. What others would you add to this admittedly partial list?
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
