Researchers from North Carolina State University have developed a new way to fine-tune wireless power transfer (WPT) receivers, making the systems more efficient and functional. The researchers have shown that it is possible to transmit power wirelessly by using magnetic resonance.

It’s
a situation we’ve all probably encountered: a coffee shop full of
laptop users and no place to sit. According to recent studies at Boston
College, “plugged-in” customers are increasingly grabbing extra seats
counter space and table tops by using cell phones, laptops, and cups of
steaming hot coffee to shield others from seemingly public spaces

Researchers at NIST have developed and published a new protocol for communicating with biometric sensors over wired and wireless networks—using some of the same technologies that underpin the Web.

Multi-hop wireless networks can provide data access for large and
unconventional spaces, but they have long faced significant limits on
the
amount of data they can transmit. Now researchers from North Carolina
State
University have developed
a more efficient data transmission approach that can boost the amount of
data
the networks can transmit by 20% to 80%.

Spectrum
rights are the lifeblood of the wireless industry, since they're
necessary to operate wireless networks. On Wednesday, Verizon Wireless
said it will auction a parcel of radio frequencies potentially worth
billions of dollars in an industry scrambling to offer consumers more
cellular broadband.

Scientists
have for decades contemplated communicating via neutrinos when other
methods won’t do. For the first time, physicists and engineers at Fermi
National Accelerator Laboratory’s MINERvA detector have successfully
transmitted a message through 240 m of rock using these ghost-like
particles.

Technological
advances have produced implantable, electronic solutions for dosing and
therapeutic functions in humans. However, these medical devices use
probes, actuators, and electronic controls that need power. Researchers
at the Fraunhofer Institute for Ceramic Technologies have recently
succeeded in wirelessly transmitting power from a portable transmitter
module to a receiver, offering the possibility of wirelessly-powered
medical devices.

Students in a Purdue University service-learning program have developed an application for Apple's iPad that helps children with severe autism learn how to communicate. The app, called SPEAKall!, allows the children to construct sentences by choosing photos and graphic symbols.

A group of scientists led
by researchers from the University of Rochester and North Carolina State
University have, for the first time, sent a message using a beam of
neutrinos—nearly
massless particles that travel at almost the speed of light. The message
was
sent through 240 m of stone and said simply, "Neutrino."

A
group of Italian and Swedish researchers appears to have solved the
problem of radio congestion by cleverly twisting radio waves into the
shape of fusilli pasta, allowing a potentially infinite number of
channels to be broadcast and received. To demonstrate, they did this in
real-life conditions by beaming two corkscrewed radio waves across the
waters of Venice, Italy.
