Engineers Put 'Spring' in Robots' Step

The ATRIAS robot model developed at Oregon State University uses a "spring-mass" walking approach. The natural-gait method gives human-sized bipedal robots the ability to blindly react to rough terrain, maintain balance, retain an efficiency of motion, and walk like humans.

Computer Aided Design of Suspension Mechanisms

Automobile suspension mechanisms have to date been designed using two-dimensional graphic oriented methods. Computer-aided design has allowed many two-dimensional mechanisms to be designed much more accurately. However, this has not translated to suspension mechanisms because these mechanisms are not two-dimensional but instead three-dimensional.

Advances in Bluetooth Low Energy Technology to Power Wireless Medical Devices

The trend for drug delivery, diagnostic and other medical devices is towards ‘smaller and smarter.’ The devices are focusing on high functionality and intuitiveness, resulting in improved therapy, better compliance and lower patient cost. Wireless connections are making it easier to ensure patient compliance. But, these ‘smaller and smarter’ devices require integrated electronics.

Do the benefits of drone registration outweigh the drawbacks?

This week's Question: Last week, the U.S. Transportation Department and Federal Aviation Administration announced that drone hobbyists will have to register their aircraft or face unspecified penalties. The move is an attempt to prevent the unmanned aircraft from compromising air safety, as the number of complaints about errant flyers has grown in recent months. Challenges remain, however, including which drones will require registration, how users will register the devices, and whether the policy will apply to devices that have already been sold or have been 3D-printed. What do you think? Do the benefits of drone registration outweigh the drawbacks?

Sense Element Pump Ripple Fatigue

Aerospace sensor technology is plagued by the balance between sensitivity and durability. As devices become more fragile in the pursuit of achieving higher accuracy they find themselves torn apart in the process. Hydra-Electric solves this using a special sense element of stainless steel construction capable of withstanding the harshest pressure spike environments without the use of a snubber. Using finite element analysis, it was revealed that near infinite fatigue life is achieved even in high pressure applications. This demonstrates the superiority of a stainless steel flexure sense element over conventional piezoresistive silicon (PRT).

New Sensor Peers Inside Fingertip

Scientists from The Langevin Institute, Paris, France, have constructed a new fingerprint imaging system that peers inside the finger to take a picture — a more reliable and secure way of identifying individuals. The fingerprint sensor, based on full field optical coherence tomography (FF-OCT), uses an inexpensive fast camera.

Amy Keith, Environmental Engineer, Marshall Space Flight Center, Huntsville, AL

Environmental engineer Amy Keith and her team developed a low-cost detector of contaminants in plants and surrounding groundwater. The non-destructive technology scans the surface of a leaf for spectral signatures. NASA currently seeks a development partner for the hyperspectral estimator.
