Pasternack Enterprises Inc., a manufacturer and supplier of radiofrequency (RF) products, has introduced a new 60 GHz Waveguide Transmitter/Receiver Modules and Development System which enables experimentation and development in the globally-unlicensed 60 GHz ISM frequency band.
A recent study from the Massachusetts Institute of Technology describing how graphene can be used to convert signals from optical to electrical has also been explored by engineers in Austria, who have also constructed a graphene light detector on a semiconductor chip. According to the researchers, graphene can convert all light wavelengths which are used in telecommunications.
Those separated from family and friends by long distances often use video conferencing services such as Skype in order to see each other when talking. But who hasn’t experienced the frustration of your counterpart not making direct eye contact during the conversation? A software prototype from the laboratories ETH Zurich may be able to help by leveraging the color and depth information made available by XBox Kinect cameras.
When NASA’s Lunar Laser Communication Demonstration (LLCD) begins operation aboard the Lunar Atmosphere and Dust Environment Explorer (LADEE), it will attempt to show two-way laser communication beyond Earth is possible, expanding the possibility of transmitting huge amounts of data. This new ability could one day allow for 3-D high-definition video transmissions in deep space to become routine.
Made in Texas, Motorola’s new Moto X is the first smartphone to carry the "Made in the U.S.A." designation. Labor costs are higher in the U.S. compared with Asian factories, where phones are typically made. But IHS said the Moto X is about 5% cheaper to make than Samsung Electronic Co.'s flagship Galaxy S4 phone.
What happens to a resonant wireless power transfer system in the presence of complex electromagnetic environments, such as metal plates? A team of researchers has explored the influences at play in this type of situation, and they describe how efficient wireless power transfer can be achieved in the presence of metal plates.
China's population of Internet users has grown to 591 million, driven by a 20% rise over the past year in the number of people who surf the Web from smartphones and other wireless devices, an industry group reported Wednesday. The rise of Web use has driven the growth of new Chinese industries from online shopping and microblogs to online video.
A*STAR Institute of Microelectronics in Singapore and OPUS Microsystems Corp., a Taiwan-based company specializing in microelectromechanical systems (MEMS) scanning mirror devices, have signed an agreement to refine and develop a MEMS scanning mirror for smartphones applications. The goal is to shrink the MEMS micromirror to allow a pico-projector level of operation.
Researchers of the Univ. of Stuttgart have achieved a new world record in coupling efficiency between optical fibers and integrated silicon waveguides. The breakthrough, which resulted in a coupling efficiency of 87%, was based on newly developed aperiodic grating coupler structures optimized at the nanoscale.
Digital systems are an everyday routine for more and more passengers, and even Internet is now available. But pilots are largely cut off from this development with a system that is separate and largely analog. Under development in Germany is a new system that will digitally transmit air traffic and weather communications with the ground and via satellite at high speeds.
Eighteen months in the works, the top-secret project was announced Saturday in New Zealand, where up to 50 volunteer households are already beginning to receive the Internet briefly on their home computers via translucent helium balloons that sail by on the wind 12 miles above Earth. Google is launching these Internet-beaming antennas into the stratosphere aboard giant, jellyfish-shaped balloons.
Americans are accustomed to calling 9-1-1 to get help in an emergency. A research team lead by Ram Dantu of the University of North Texas sees the growth of cell phone and smartphone usage as an opportunity to improve 9-1-1 response. His team has designed several innovative smart phone apps that virtually place 9-1-1 operators at the scene of an emergency, allowing faster response.
Forget to turn off the lights before leaving the apartment? No problem. Just raise your hand, finger-swipe the air, and your lights will power down. Using the common Wi-Fi signals generated by a commercial router, University of Washington computer scientists have developed gesture-recognition technology that brings this a step closer to reality.
Facebook Home, the new software that takes over the front screen of a smartphone, is a bit of a corporate home invasion. Facebook is essentially moving into Google's turf, taking advantage of software the search giant and competitor created. Launching April 12, Home will operate on phones running Google Inc.'s Android software and present Facebook status updates, messages, and other content without making the user fire up Facebook's app.
A team that includes researchers from Sweden has successfully created a magnetic soliton, a spin torque-generated nano-droplet that could lead to technological innovation in such areas as mobile telecommunications. This construct was first theorized 35 years ago and scientists have long believed that they exist in magnetic environments, but until now they had never been observed
The space terminal for the Lunar Laser Communication Demonstration (LLCD), NASA's first high-data-rate laser communication system, was recently integrated onto the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft at NASA's Ames Research Center, Moffett Field, Calif. LLCD will demonstrate laser communications from lunar orbit to Earth at six times the rate of the best modern-day advanced radio communication systems.
NIST is changing the way it broadcasts time signals that synchronize radio-controlled "atomic" clocks and watches to official U.S. time. This new time broadcast protocol will not only improve the performance of new radio-controlled clocks and watches, but will encourage the development of new timekeeping products that were not practical with the old broadcast system because of local interference.
There are various boxes today that bring Internet content to TV sets, with popular ones made by Roku and Apple. But Intel Corp. wants to go further and make its box and streaming service a replacement for cable. The company said Tuesday that it will sell a set-top box that brings Internet-delivered movies and shows to a TV set this year, along with a “vastly superior experience” to today’s cable boxes.
Researchers in Japan and Germany have recently demonstrated a device that can focus and steer terahertz beams electrically. Based on an array of metal cantilevers which can be micromechanically actuated by electrostatic forces, the device can create tunable gratings that may be crucial in future terahertz wavelength communication systems.
It’s already possible to open doors using an app, but we are a long way from seeing widespread acceptance of this in the market. Now, researchers have developed a piece of software that will make the technology even more secure and versatile.
Intelligent radio-over-fiber (I-ROF) systems combine the advantages of flexible wireless access and fiber-optic broadband transmission, using methods of microwave photonics to generate microwave signals in the optical domain. A research group in China has built an experimental I-ROF platform that may offer a way to significantly increase the availability of broadband wireless.
Digital cameras and camcorders deliver high resolution film sequences that are several gigabytes in size. These can take several minutes to transfer wirelessly to your home computer via Bluetooth. A researcher in Germany has come up with a speedier alternative: a “multi-gigabit communication module” that is six times faster than a USB cable.
Developed by a company in San Diego, a new automated system that lets consumers trade in cell phones and mobile devices for reimbursement or recycling relies artificial intelliigence and sophisticated machine vision diagnostics. The building blocks for the ecoATM have existed for many years, but none, until now, have been applied to the particular problem of consumer recycling.
According to data from a 2008 Business R&D and Innovation Survey by the National Science Foundation, businesses perform the lion's share of their R&D activity in just a small number of geographic areas, particularly the San Jose-San Francisco-Oakland area and the New York-Newark-Bridgeport area.
