The operators of Indiana's largest wind farm are proposing changing the nighttime operations of the farm's 300-plus wind turbines to protect endangered Indiana bats from being killed by the turbines' spinning blades. Two of the mouse-sized federally protected species have been found dead since...
Cree, Inc. (Durham, NC) (Nasdaq: CREE) has introduced the industry’s first commercially available silicon carbide (SiC) six-pack power module. When compared to state-of-the-art silicon modules, the SiC 1.2 kV, 50 A modules deliver performance equivalent to silicon modules rated at 150 A.
Excelitas Technologies (Waltham, MA) has announced the Low-Power DigiPyro PYD 1688. As part of the industry’s one and only Digital Pyroelectric Infrared Detector Family, the new DigiPyro PYD 1688 was developed for use in both residential and commercial products.
The way in which radio spectrum is currently allocated to different wireless technologies can lead to gross inefficiencies. In some regions, for instance, the frequencies used by cellphones can be desperately congested, while large swaths of the broadcast-television spectrum stand idle.
This week on WDD's HotSpot, a netbook-like combo that uses a smartphone for its computing power, new microbatteries for a balance between energy and density, satellites that listen in on ADS, and a sound camera that shows the location of troublesome noises in machinery.
The atom-sized world of carbon nanotubes holds great promise for a future demanding smaller and faster electronic components. Nanotubes are stronger than steel and smaller than any element of silicon-based electronics—the ubiquitous component of today's electrical devices—and have better conductivity, which means they can potentially process information faster while using less energy.
There are many old and decrepit residential buildings in Moscow in need of refurbishment. VTT Technical Research Centre of Finland has developed three repair concepts for improv-ing the energy efficiency of both buildings and entire residential districts while also reducing their environmental impact.
Omron has announced the release of a new Differential Pressure Type MEMs Flow Sensor with an I2C output. The sensor uses the proprietary Omron mass flow MEMs chip, however, the internal flow path has been redesigned to produce a low flow, high velocity/high impedance sensor that will output a differential pressure.
Friction is an omnipresent but often annoying physical phänomenon: It causes wear and energy loss in machines as well as in our joints. In search of low-friction components for ever smaller components, a team of physicists led by the professors Thorsten Hugel and Alexander Holleitner now discovered a previously unknown type of friction that they call “desorption stick.”
Their project might not sound like much: The college students on Wednesday launched a tiny model of a satellite the size of a Coke can on a big yellow balloon. It went aloft to a height of 165 meters (yards) and then came back down attached to a red parachute.
POSITAL's (Hamilton, NJ) versatile inclinometers and absolute rotary encoders are now available with J1939 communications interfaces. POSITAL's versatile inclinometers and absolute rotary encoders are now available with J1939 communications interfaces.
Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Yet other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using nanoscale particles of these active materials. Engineers call them nanoscavengers.
Steinbichler Optotechnik GmbH (Neubeuern) has announced the new COMET 6 16M high-end sensor for 3D digitalization. The unique concept of the STEINBICHLER COMET 6 16 M is based on a modular structure with the tried-and-tested single-camera technology so that the measurement field size can be quickly adapted to the measuring task at hand.
Calling balls, strikes, and checked swings could be a thing of the past in amateur ball if the Eagle Eye Electronic Home Plate is all that inventor Jerry Spessard claims. He has enough faith in the product to begin construction of a plant in Hancock this June, with production expected to begin by fall.
Aereo, the startup that offers live television broadcasts over the Internet starting at $8 a month, said it will start service in the Atlanta market on June 17, following an expansion to Boston on Wednesday. Until this week, the service had been available only in the New York City area.
