Mud Fueled Smart Sensors for the Bottom of the Ocean

ghIf you put tiny electrodes in the mud on the ocean floor, you can harvest enough energy to power a tiny sensor platform that can monitor what’s going on at those depths.

So say researchers from the University of Michigan at Ann Arbor, in a recent issue of IEEE Transactions on Circuits and Systems I. Together with collaborators from Korea and California, they have designed a self-sustaining sensor platform for oceanic sensing applications that is powered entirely by small-scale benthic microbial fuel cells.

“We wanted a platform that could run off very small harvesting sources,” Michigan electrical engineering professor and IEEE Fellow David Blaauw tells IEEE Spectrum. “If you can get power consumption down enough, there are all sorts of things you can use. Even plants produce little bits of voltage,” he says.

When benthic bacteria are in an anaerobic environment, their metabolism produces electric current. “It’s been well studied,” says Blaauw, “but in the past, people have struggled to get enough current to run something.”

 According to Blaauw, laboratory experiments confirmed that if a microbial fuel cell sits in the sediment, with the cathode floating in a water column

Car Camera Network Could Produce Virtual Maps of Pedestrians

poiA growing fleet of smart cars may add their street camera views to those of the surveillance camera networks already covering many major cities. That could open the door for a new technology that enables different video cameras to “talk” with one another and track the same individual person across many different camera views—possibly giving rise to Google Earth style maps that can display pedestrian and vehicle traffic.

The technology is based on a computer algorithm that can compare different camera views of the same person and learn to recognize the same individuals across many camera views by focusing on body color, texture and movement. Researchers envision a large-scale version of the system tracking pedestrian traffic on a virtual map—perhaps displayed on a car’s GPS screen—or enabling police to easily track fleeing suspects across multiple surveillance camera views.

“Our idea is to enable the dynamic visualization of the realistic situation of humans walking on the road and sidewalks, so eventually people can see the animated version of the real-time dynamics of city streets on a platform like Google Earth,” said Jenq-Neng Hwang, a professor of electrical engineering at the University of Washington, in a news release.

Metasurface Optics for Better Cellphone Cameras and 3D Displays

gfEngineers at the California Institute of Technology have created a metasurface out of tiny pillars of silicon that act as waveguides for light. The way they arrange the pillars allows them to control the phase of light passing through the surface; this ability gives them control over how the light is focused, as well as its polarization, which is important for uses such as liquid crystal displays and 3-D glasses. Metasurfaces are structured planes so thin that they count as being two-dimensional; their periodic designs manipulate light in unusual ways.

“We’re trying to create kind of a new platform for optics,” says Amir Arbabi, a postdoc in Andrei Faraon’s Nanoscale and Quantum Optics Lab. The team described their work in the latest issue of Nature Nanotechnology.

The silicon pillars have to be somewhat shorter than the wavelength of light they’re designed to manipulate. In the case of the metasurface described in the paper, the pillars are 715 nanometers tall, to handle infrared light with a wavelength of 915 nm. But they could easily be made shorter for visible light, Arbabi says. The pillars range in diameter from

Powerbank Basics Li polymer and Li ion Battery Cells

So, as you know well that powerbanks constitute of battery cells much similar to that of the smartphones. The question might have come into your mind that what are the types of the powerbank cells and do they decide the performances and functions of the powerbank. To agree with you, it is exactly so. The basic two kind of powerbank batteries which generally constitute ordinarily available powerbanks are Li-ion and Li-poly.

What is Lithium-ion Battery

Li-ion is nothing but the abbreviation of the full word Lithium ion batteries. These batteries are most commonly used in most of the portable devices which uses portable cells having higher charge holding capacity per unit size. thus for the Li-ion cells, you will be able to come up detecting Li-ion batteries able to be of higher capacity even after being smaller.

Safety of Li-ion Battery

The most aspect of concern for the Li-ion batteries is basically the safety aspect. It is generally much prone to get exploded in comparison to that of the Lithium Polymer, but to mention the fact in right way, even Lithium-ion Batteries are now being manufactured as per tier basis, and the tier 1 Lithium-ion batteries which are normally chosen by the reputed powerbank

HIP Home Information Packs Explained

It’s been quite some time since they were first introduced by the government to the common man but the controversy just refuses to die down. While the government has been propagating the Home Information Pack (HIP) as being extremely beneficial to the people and one that would bring much more transparency to the field, the critiques just won’t buy it. And what’s interesting is that some of the most vociferous of these critiques come from the political arena. Leading the charge, as we all know, are the Tories.
HIP’s has been on the political agenda for quite some time since the Government introduced them. Essentially, the Home Information Packs (HIP) were proposed to be a one-stop shop for anything that you wanted to know about a particular property that seemed to be interesting. The first stage of the roll out of the HIP’s began in 2007. Initially, things took time to get going with only the large houses (ones that had five bedrooms or more) being put on the cards. But, by 2008 and as of now, all properties, regardless of the size, need to have an HIP before they can be sold.
The Conservatives have been pretty clear on

5 Mobile App Development Trends to Look Out for In the Recent Future

Today, mobile device has emerged as a true friend in need, playing an important role in simplifying the routine tasks. We can’t deny the fact that the mobile technology is growing at a rapid pace and the mobile apps have become an integral part of the digital ecosystem. They are progressing to become omnipresent; so, staying up-to-date with the latest mobile app development trends has become an order rather than an option.
Below mentioned are a few mobile app development trends to look out for in the recent future:
  1. Connection to Back-End Systems: More and more users are demanding this feature quite often. And yes, it’s for the right reasons. Just imagine yourself sitting in front of a desktop computer looking for a product and you have to leave the house before you could finalize the order. You don’t have to worry if you have a mobile app as you can check out the offers on the go; but what if the app doesn’t have a shopping cart? This is where you feel that the app is useless. The app must be able to provide all the services as the desktop website; i.e. the apps must be connected to backend

4 Expert Tips For Being a Good Live Chat Agent

Being a live chat operator, your job isn’t easy. You have to be on your toes all the time and a lot is expected from you. You are not allowed to take extra breaks, and are ordered to stay focused. It is understandable for you to take the toll of the job, and sometimes it is frustrating to handle unbearable customers when you are loaded with a lot of work. But, if you channel your responsibilities wisely, and learn some rules by heart, your job as a live chat support operator might become easier.

Here are some useful expert advices that can help:

Just listen and don’t take anything personal

When the customer starts screaming, not many operators have the temperament to stay cool and quite a few retaliate and argue back. As said above, this act might be credited to the pressure of work, but most of the times it is so because operators take rude comments personally. You must always keep in mind that whatever the customer is saying has nothing to do with you, he does not even know who you are, and he is just angry at the company and venting out his frustration on you. So, the best

Measure Liquids to Know the Price Cost

Modern safety protocols demand the factory management to be aware of the amount of liquids that go in the waste pipelines. Since the waste liquids often fall in the city’s main waste pipeline, it often gets mixed up in places it shouldn’t have been. Most of the waste water is dumped into the river which then travels all through the country to fall into the ocean. Thus it not only makes the rivers toxic, but all the lands that take water from the river. One of the biggest challenges faced by the factories of today is controlling waste. Be it a waste of solid raw materials or liquids, anything that goes into the waste without being properly used increases production costs. While the competition grows globally, it has become necessary to bring down production costs to as minimum as possible.

When a factory does not control its costs incurred in production, ultimately the product when released to the market costs high and consumers do not purchase it. Thus, a huge loss is incurred and no business can function properly when it faces losses in huge amounts. Factory owners are now aware of the fact and we can

Tardis Memory Could Enable Huge Multi Core Computer Chips

Future generations of computer chips could become much more powerful, with processors containing hundreds or even thousands of cores. But these huge multi-core processors will also require loads of memory so their directories can keep track of data on each individual core and coordinate updates to shared data. A new MIT technique promises to greatly reduce the required memory for such coordination as multi-core processors scale up in the coming years.

The new MIT system, called Tardis, coordinates the shared data on multi-core processors much more efficiently than existing directory techniques, according to an MIT press release. As a result, the required memory increases according to the logarithm of the number of cores instead of in direct proportion to the number of cores. So, a future 128-core chip might need only one-third the memory of a comparable chip based on an existing directory system. Memory savings become even greater as the number of cores increases: 80 percent in memory savings for a 256-core chip and 96 percent for a 1,000-core chip.

MIT’s group plans to present a paper on its new technique at the International Conference on Parallel Architectures and Compilation Techniques in October.

So how does Tardis improve on the existing system? Today’s multi-core chips have directories to make

Sharing Content Wirelessly with Apple AirDrop

Not too long ago, my mother called me in a panic. “Tim, I lost all the contacts on my iPad! Will I have to manually re-create them all again?”

The good news for my mom is that I already knew that (a) she had a copy of her contacts database on another iDevice at her home, and (b) we could use AirDrop to copy those missing contacts back to her iPad with no muss or fuss.

In just a few minutes, you too will understand how easy and convenient AirDrop makes copying content between iDevices without the hassle of wires or complicated setups.

What Exactly Is AirDrop?

AirDrop is an Apple-only technology that uses wireless, peer-to-peer networking to support near-range file transfers. Do you remember how we used infrared (IR) to swap data in the “bad old days” of early cell phones and personal digital assistants (PDAs)? Think of AirDrop as a 21st century counterpart.

Whereas infrared required line-of-sight and very close ranges (I remember my colleagues and I literally bumping our Palm Pilots against each other to catch a signal), AirDrop has a much more reasonable 30-foot range. Because AirDrop uses Wi-Fi

Intel and Micron Announce Revolutionary Mystery Memory

This week, Intel and Micron announced 3D XPoint (“crosspoint”), a new form of nonvolatile memory that the companies say is 1000 times speedier than NAND Flash and ten times denser than DRAM. But what exactly is it? Good luck trying to figure it out.

“They’re being pointedly vague,” says Jim Handy, a memory analyst of Objective Analysis in Los Gatos, Calif.

A press release on Intel’s website touts this as “the first new memory category since the introduction of NAND flash in 1989”. But I’m sure a number of companies would disagree with that characterization. There’s been plenty of work done on phase-change memory and other companies are pushing hard on resistive RAM. Everspin Technologies, a Freescale Semiconductor spin-off based in Arizona, has been shipping MRAM for years.

That said, Intel and Micron are big players in the semiconductor industry. Regardless of how unique 3D Xpoint is, their backing could really help launch alternative memory from the sidelines into mainstream adoption.

Engineers have long hoped for a memory that could replace the mix we have now, something that could be speedy, dense, cheap, high endurance, and low power. Joel Hruska at ExtremeTech does a good job explaining how 3D Xpoint compares with existing memories based on the information currently available (he notes the 1000x-faster-Flash claim is somewhat vague

Five Innovative Ways to Use an iPhone or iPad When You Travel

Almost anywhere you travel in the world these days—especially to any First World country or popular tourist destination—a strong cellular signal and Wi-Fi hotspots in hotels, restaurants, Internet cafes, shopping centers, and airports are readily available.

So even though you may be on the opposite side of the world from where you live, your iPhone or iPad can still serve as a powerful communication, organization, and productivity tool, as well as an interactive entertainment device.

The following five sections discuss ways you can use your iPhone or iPad while you’re traveling in order to be more productive; stay in contact with friends, family, and coworkers; save time; and make the information you need readily available at your fingertips.

1: Use Your iPhone or iPad to Make and Receive Skype Calls

As soon as you leave the United States, your unlimited voice plan for making and receiving calls from your iPhone (or any smartphone) no longer applies. With most cellular service providers, each time you engage in a call, you wind up paying extremely costly international roaming fees. To avoid these charges and to be able to make and receive calls from your iPhone or

Introduction to the New Pebble Time Smart Watch

When the original Pebble smart watch was first announced in 2012, it was introduced as a concept that the inventors needed to raise funds in order to build. They turned to crowd funding via Kickstarter.com, and quickly became the online service’s biggest success story, after raising more than $10 million.

Since then, Pebble has sold more than one million first generation smart watches, but has also been focusing on innovative ways to improve upon the product. In late March 2015, Pebble completed a second crowd funding campaign in preparation for the launch of its second-generation smart watch, called Pebble Time. This time, the company quickly raised in excess of $20.3 million, thanks to almost 79,000 crowd funding backers.

Pebble Time Offers Greatly Expanded Features and Functions

Within days after announcing Pebble Time, hundreds of third-party app developers began developing cutting-edge apps for this new smart watch, which boasts a full color e-paper display and a seven day battery life. It also contains a built-in microphone, accelerometer, can communicate wirelessly with a smartphone via Bluetooth 4.0, and it runs using a re-designed operating system (Pebble OS).

Plus, in addition working in conjunction with the iPhone,

Why IoT Needs 5G

When 5G, the fifth generation of wireless communications technology, arrives in 2020, engineers expect that it will be able to handle about 1000 times more mobile data than today’s cellular systems. It will also become the backbone of the Internet of Things (IoT), linking up fixed and mobile devices—vending machines and cars alike—becoming part of a new industrial and economic revolution, some say.  A new architecture, new communication technologies, and new hardware will make this transformation possible.  A research team comprising Zhiguo Ding at Lancaster University and researchers at China’s Southwest Jiaotong University have took stock of the recent research and future needs of 5G in a review last month in Science China [pdf].  In a Skype interview Ding spoke to Spectrum about his views on how 5G will take shape in the near future.

Spectrum: 4G is now being deployed in many countries, but is it already out of date?

Ding: Actually 4G is good for now, however if you would look at it in five or ten years, 4G will obviously not be able to meet requirements for new applications coming up in the next few years.  With 5G we will increase the data rate, reduce the end-to-end latency , and improve coverage.  These properties are particularly important for many applications related to IoT. One example is emerging autonomous cars and

LEGO Has Gone Interactive

When most adults think of LEGO, what comes to mind are multicolored plastic bricks that can be used to tap people’s imagination as they create, build, interact, and play.

For more than 80 years, LEGO bricks have been a staple toy found within millions of toy chests. During the past decade, however, LEGO’s product line has expanded dramatically, but those plastic building bricks have remained the centerpiece of the company’s offerings.

It All Started with Colorful Plastic Bricks…

As technology has progressed, so has the LEGO play experience. LEGO Legends of CHIMA: Speedorz, LEGO Star Wars: The Complete Saga, LEGO Star Wars: The Yoda Chronicles, LEGO The Lord of the Rings, and a handful of other iPhone and iPad game apps are currently available for purchase from the App Store.

For those who don’t want to store hundreds or thousands of plastic LEGO pieces in their home, there’s the LEGO Digital Designer app for PCs and Macs. This is a virtual LEGO set, in the form of free downloadable software (http://ldd.lego.com/en-us/) that allows for hundreds of different LEGO models to be virtually built on the computer screen and then shared electronically with others.

Holography Makes 3 D On Chip Batteries

By employing the principles used to make holograms, scientists have developed microscopic high-energy, high-power 3-D lithium-ion batteries that they can fabricate directly on microchips.

Existing thin-film microbatteries can deliver high levels of power, but when sized to store a reasonable amounts of energy they take up too much of a chip’s area. To reduce the battery’s footprint and improve microbattery performance inventors have sought to expand into the third dimension with complex 3-D structures that increase the amount of surface area available for electricity-generating chemical reactions. However, it has proven challenging.

Now scientists at the University of Illinois at Urbana-Champaign are using the same principles employed to make holograms to help create advanced 3-D microbatteries. Holography uses patterns of laser beams that interfere with each other in precise ways to encode holograms. Holographic lithography systems fire laser beams at a photosensitive material, and the way these beams interfere with each other can make complex 3-D structures harden into existence in that material in just seconds. The researchers noted that 3-D holographic lithography is highly scalable and compatible with existing microfabrication techniques.

The researchers developed a 10-micrometer-thick 4-square-millimeter 3-D microbattery that could reach a peak current of 500 microamperes, store
