PEEPING SUBMARINE: Brush motors get commands from a smartphone
An underwater remotely operated vehicle using an Android-based smartphone or iPad as a controller lets those on the surface garner close-up views of life under the sea. The HydroView, from Aquabotix Technology Corp.
Going places with long-travel piezomotors
Piezomotors burst through travel limitations to bring precise control over long distances.
Spray-on battery turns almost any surface into a power source
Researchers at Rice University have developed a lithium-ion battery that can be painted on virtually any surface. The spray-on power source consists of five spray-painted layers, each representing components in a traditional battery
Sensor Sense: Ultrasonic anemometers
Anemometers simply measure wind speed. Many designs use the wind to spin a fan or other mechanical device.
Put a CAP in it!
The spotlight may currently be on renewable energy, but energy storage has a high priority as well.
New chips offer efficiency with accuracy? Not exactly…
Prototypes of a new computer chip recently unveiled at the ACM International Conference on Computing Frontiers are 15 times more efficient than equivalent chips made using current production technology, promising major power reductions and extended battery life for portable devices.
India beefs up its automotive testing
When one thinks about countries noted for their automobiles, thoughts usually turn to Germany, Italy, France, and, of course, the U.’S. India as an automotive manufacturer seldom comes to mind.
Exploring Rotary Ball Splines
Angular-contact ball bearings or crossedroller bearings? A few factors help determine the pros and cons of each type
Sensor Sense: Inclination and tilt detectors
An inclination or tilt sensor provides angular-tilt information relative to gravitational force. This information can then be used to change the characteristics of the device
Stepper motors keep seismometers on the level in Davy Jones’ locker
Geophysicists like to keep tabs on the motion of earth’s tectonic plates and the earthquakes they generate using a device known as a seismometer
Speedy memory chip uses low-power resistive RAM
Researchers at University College London (UCL) have developed the first purely silicon-oxidebased resistive RAM chip that can operate under ambient conditions
World’s biggest sensor: an ice cube?
Or more precisely, the IceCube Detector, part of the South Pole Neutrino Observatory that searches for one of the most elusive of the low-mass subatomic particles: the neutrino
Prewired motor plug speeds service and repair
A new motor connector lets qualified employees connect or disconnect motors, pumps, generators, and other electrical equipment quickly and safely by simply plugging them in
More Smarts, Less Energy
Powerful embedded processors help make more applications energy efficient
CMOS imager peers through objects
Researchers at the University of Texas at Dallas (UT Dallas) have designed an imager chip that could let cameras and mobile phones see through walls, wood, plastics, paper, and other objects
