San diego demonstrated a new wireless communication technique that works by sending magnetic signals through the human body.
and more secure way to communicate information between wearable electronic devices, providing an improved alternative to existing wireless communication systems,
such as smart watches, fitness trackers and health monitors. All of these devices will need to communicate information with each other.
Currently, these devices transmit information using Bluetooth radios, which use a lot of power to communicate. We're trying to find new ways to communicate information around the human body that use much less power,
a professor in the Department of Electrical and Computer engineering at UC San diego who led the study.
Communicating magnetic signals through the human body The new study presents a solution to some of the main barriers of other wireless communication systems:
Bluetooth technology uses electromagnetic radiation to transmit data, however these radio signals do not easily pass through the human body
and therefore require a power boost to help overcome this signal obstruction, or"path loss."
Researchers showed that the path losses associated with magnetic field human body communication are upwards of 10 million times lower than those associated with Bluetooth radios."
"This technique, to our knowledge, achieves the lowest path losses out of any wireless human body communication system that's been demonstrated so far.
This technique will allow us to build much lower power wearable devices, "said Mercier. Lower power consumption also leads to longer battery life."
"A problem with wearable devices like smart watches is that they have short operating times because they are limited to using small batteries.
With this magnetic field human body communication system, we hope to significantly reduce power consumption as well as how frequently users need to recharge their devices,
Since this technique is intended for applications in ultra low power communication systems the transmitting power of the magnetic signals sent through the body is expected to be many times lower than that of MRI SCANNERS and wireless implant devices.
Another potential advantage of magnetic field human body communication is that it could offer more security than Bluetooth networks.
Because Bluetooth radio communicates data over the air, anyone standing within 30 feet can potentially eavesdrop on that communication link.
To put this in the context of a personal full-body wireless communication network, information would neither be radiated off the body nor be transmitted from one person to another."

#New technology transforms cell phone into high-powered microscope New technology that transforms a cell phone into a powerful,
and feel to a protective phone case, makes use of a smart phone's camera features to produce high-resolution images of objects 10 times smaller than the thickness of a human hair,
says Gerard Coté, professor of biomedical engineering and director of the Texas A&m Engineering Experiment Station's Center for Remote Health Technologies and Systems.
Coté's development of the instrument, known as a mobile-optical-polarization imaging device (MOPID), is detailed in the online scientific journal Scientific Reports,
when observed through the phone's camera lens--enabling an instant, accurate diagnosis. While polarized light has been preferred the option for malaria detection due to its increased sensitivity,
"What we've achieved with MOPID is the design of a polarized microscope platform using a cell phone,
Coté's solution takes advantage of existing mobile phone technology and networks--something to which a whopping 75 percent of the world has access.
This ever-increasing access to mobile networks and the fact that most mobile phones are equipped with advanced camera features make mobile phones the ideal platform for advanced imaging applications such as MOPID,
and specificity to detect malaria with both ios -and Android-based devices and requires less user expertise than traditional microscopy,
Coté says. That user friendly aspect, coupled with the system's portability and expected low cost of about $10 per unit, makes it an easily adoptable technology in low-resource areas ravaged by malaria,
he adds. What's more, analysis of a blood sample can be made instantaneously with the patient in the field without the need for a mobile network,
says Coté, who notes that a network is required only for transmitting the images to a central location for further analysis or storage."
The technology was among the top award winners in the Texas instruments Innovation Challenge this past summer.
The technology, developed in collaboration with Texas instruments, represents a growing interest in the development of high-tech sign language recognition systems (SLRS) but unlike other recent initiatives,
and the videos or images captured may be considered invasive to the user's privacy. What's more,
because these systems require a user to gesture in front of a camera, they have limited wearability--and wearability,
This sensor plays a major role in discriminating different signs by capturing the user's hand orientations and hand and arm movements during a gesture.
In Jafari's system both inertial sensors and electromyographic sensors are placed on the right wrist of the user where they detect gestures
and send information via Bluetooth to an external laptop that performs complex algorithms to interpret the sign
and display the correct English word for the gesture. As Jafari continues to develop the technology,
he says his team will look to incorporate all of these functions into one wearable device by combining the hardware and reducing the overall size of the required electronics.
He envisions the device collecting the data produced from a gesture interpreting it and then sending the corresponding English word to another person's smart device
so that he or she can understand what is being signed simply by reading the screen of their own device.
In addition, because many labs use their own software to examine CNVS, there is little consistency in how researchers analyze their results.

#Key component for terahertz wireless networks Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today's cellular or Wi-fi networks.
But there remain many technical challenges to be solved before terahertz wireless is ready for prime time.
Multiplexers are devices that enable separate streams of data to travel through a single medium.
It's the technology that makes it possible for a single cable to carry multiple TV channels
or for a fiber optic line to carry thousands of phone calls at the same time.""Any terahertz communications application is going to need some form of multiplexing
Today's cellular and Wi-fi networks rely on microwaves to carry voice conversations and data. But the increasing demands for data transfer are quickly becoming more than microwaves can handle.
Terahertz waves have a much higher frequency and therefore more potential bandwidth. Scientists and engineers have begun only recently exploring the potential of terahertz waves, however.
"That means if you put in 10 different frequencies between the plates--each of them potentially carrying a unique data stream--they'll come out at 10 different angles,
thus receiving data from only one stream.""We think it's definitely a reasonable solution to meet the needs of a terahertz communication network,
when such a device is deployed for use in a data network.""For example, if one user suddenly needs a ton of bandwidth,
you can take it from others on the network who don't need as much just by changing the plate spacing at the right location,
therefore very important and contribute to the outlook where only five out of ten patients will survive for at least five years."

'First anti-fraud system to use existing credit card readers From large-scale data breaches such as the 2013 Target case to local schemes that use skimming devices to steal data at the gas pump,
The key challenge is that existing magnetic card readers use plain text to store confidential information,
The research, led by Yinzhi Cao assistant professor of computer science and engineering at Lehigh University (Bethlehem, PA) with coauthors Xiang Pan and Yan Chen from Northwestern University
and at the same time protect cardholders from mass data breaches, "said Cao. Broadly speaking, Safepay is related to Cyber-Physical Systems (CPS),
The computational elements in Safepay consist of a mobile device and a server which distributes disposable credit card numbers.
The physical entity is the magnetic credit card chip controlled by a mobile application inside a customer's mobile device.
The paper outlines the overall architecture and server-side deployment model the design of Safepay, prototype implementation and security analysis. Here's how it works:
First, the user downloads and executes the mobile banking application which communicates with the bank server.
During transactions, the mobile application acquires disposable credit card numbers from the bank server, generates a wave file,
plays the file to generate electrical current, and then drives the magnetic card chip via an audio jack
or Bluetooth The critical elements that make Safepay unique are: Disposable credit card information that expires after a limited time or number of usages (i e.,
A mobile banking application that automates the process making it extremely user friendly. Cao and his colleagues conducted real-world experiments with the Safepay technology performing transactions with a vending machine
During the experiments, they used a bank application, cell phone application, and magnetic credit card chip.

#Permanent data storage with light The first all-optical permanent on-chip memory has been developed by scientists of Karlsruhe Institute of technology (KIT) and the universities of Münster, Oxford, and Exeter.
This is an important step on the way towards optical computers. Phase change materials that change their optical properties depending on the arrangement of the atoms allow for the storage of several bits in a single cell.
With optical elements, computers can work more rapidly and more efficiently. Optical fibers have long since been used for the transmission of data with light.
But on a computer, data are processed still and stored electronically. Electronic exchange of data between processors and the memory limits the speed of modern computers.
To overcome this so-called Von neumann bottleneck, it is not sufficient to optically connect memory and processor,
as the optical signals have to be converted into electric signals again. Scientists, hence, look for methods to carry out calculations and data storage in a purely optical manner.
Scientists of KIT the University of Münster, Oxford university, and Exeter University have developed now the first all-optical, nonvolatile on-chip memory."
"Optical bits can be written at frequencies of up to a gigahertz. This allows for extremely quick data storage by our all-photonic memory,
"Professor Wolfram Pernice explains. Pernice headed a working group of the KIT Institute of Nanotechnology (INT)
"The memory is compatible not only with conventional optical fiber data transmission, but also with latest processors,"Professor Harish Bhaskaran of Oxford university adds.
The new memory can store data for decades even when the power is removed. Its capacity to store many bits in a single cell of a billionth of a meter in size (multilevel memory) also is highly attractive.
Instead of the usual information values of 0 and 1, several states can be stored in an element
The change from crystalline to amorphous (storing data) and from amorphous to crystalline (erasing data) is initiated by ultrashort light pulses.
For reading out the data, weak light pulses are used. Permanent all-optical on-chip memories might considerably increase future performance of computers
and reduce their energy consumption. Together with all-optical connections, they might reduce latencies. Energy-intensive conversion of optical signals into electronic signals and vice versa would no longer be required i
