levitating light – the floating vision with no strings attached

Published

on

Hours and hours when we used to spend on playing with magnets later when we came to know that was actually a la w in physics which explains why sometime it was very difficult to separate two magnets and similarly some time it was way too hard to place them together . that’s so because similar poles repel each other and opposite poles attracts each other .

By the time of early 20’s this game turns to some really great experimentation which gradually took a shape of worlds first levitating train with the fastest moving capability and least friction . this train was first launched in Germany and commonly know as maglev .

Now let me give you a little gymslip of some basic terms .

Lets start with levitation ; levitation is basically a process of holding up an object in air without any physical support . perhaps that sounds like a magic or something but science is nowhere less than magic .

Yes we have something very similar to that,when one day some geniuses discovered  that levitation could also be generated through magnets by just using its simple properties  say we know that similar poles repel each other so what if we have two magnets of almost similar strength and place their similar poles facing each other and here because of magnetic repulsion levitation occurs which is  simply known as magnetic levitation . now, on further this technique of levitation was experimented with many small to  large objects  which resulted into many amazing inventions that  we see around, the first and foremost  invention which we were expecting to be a part of India as bullet train “the fastest Indian train “after its huge success in Germany and other developed countries .a train which runs without wheels, which actually works on magnetic levitation simply called maglev.

Leaning towards a more closer view let see how it works .

To lift up heavy weight considerably high magnetism would be required ok so to meet this requirement we come up with this simplest solution why not use magnets of same polarity and with highest magnetism on both tracks and the base of the train ..? but wait you still need a few more things to make this more user friendly in short to make it controllable , obliviously we need to stop that train ,we need to manage its speed ,change its direction etc ..,

So now lets see how its been done ..?

Probably there are many techniques for magnetic levitation but The two notable types of maglev technologies are:

  • Electromagnetic suspension(EMS), electronically controlled electromagnets in the train attract it to a magnetically conductive (usually steel) track.
  • Electrodynamic suspension(EDS) uses superconducting electromagnets or strong permanent magnets that create a magnetic field, which induces currents in nearby metallic conductors when there is relative movement, which pushes and pulls the train towards the designed levitation position on the guide way.

Another technology, which was designed, proven mathematically, peer-reviewed, and patented, but is, as of May 2015, unbuilt, is magnetodynamic suspension (MDS). It uses the attractive magnetic force of a permanent magnet array near a steel track to lift the train and hold it in place. Other technologies such as repulsive permanent magnets and superconducting magnets have seen some research.

Now you might be wondering how these actually works ?

In electromagnetic suspension (EMS) systems, the train levitates above a steel rail while electromagnets, attached to the train, are oriented toward the rail from below. The system is typically arranged on a series of C-shaped arms, with the upper portion of the arm attached to the vehicle, and the lower inside edge containing the magnets. The rail is situated inside the C, between the upper and lower edges.

Magnetic attraction varies inversely with the cube of distance, so minor changes in distance between the magnets and the rail produce greatly varying forces. These changes in force are dynamically unstable – a slight divergence from the optimum position tends to grow, requiring sophisticated feedback systems to maintain a constant distance from the track, (approximately 15 mm (0.59 in)).

The major advantage to suspended maglev systems is that they work at all speeds, unlike electrodynamics systems, which only work at a minimum speed of about 30 km/h (19 mph). This eliminates the need for a separate low-speed suspension system, and can simplify track layout. On the downside, the dynamic instability demands fine track tolerances, which can offset this advantage.

Eric Laithwaite was concerned that to meet required tolerances, the gap between magnets and rail would have to be increased to the point where the magnets would be unreasonably large.

In practice, this problem was addressed through improved feedback systems, which support the required tolerances.

 

In electrodynamics suspension (EDS), both the guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields. In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system.The magnetic field is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable – changes in distance between the track and the magnets creates strong forces to return the system to its original position.In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed.

However, at slow speeds, the current induced in these coils and the resultant magnetic flux is not large enough to levitate the train. For this reason, the train must have wheels or some other form of landing gear to support the train until it reaches take-off speed. Since a train may stop at any location, due to equipment problems for instance, the entire track must be able to support both low- and high-speed operation.

Another downside is that the EDS system naturally creates a field in the track in front and to the rear of the lift magnets, which acts against the magnets and creates magnetic drag. This is generally only a concern at low speeds (This is one of the reasons why JR abandoned a purely repulsive system and adopted the sidewall levitation system.). At higher speeds other modes of drag dominate.

The drag force can be used to the electrodynamics system’s advantage, however, as it creates a varying force in the rails that can be used as a reactionary system to drive the train, without the need for a separate reaction plate, as in most linear motor systems. Laithwaite led development of such “traverse-flux” systems at his Imperial College laboratory. Alternatively, propulsion coils on the guideway are used to exert a force on the magnets in the train and make the train move forward. The propulsion coils that exert a force on the train are effectively a linear motor: an alternating current through the coils generates a continuously varying magnetic field that moves forward along the track. The frequency of the alternating current is synchronized to match the speed of the train. The offset between the field exerted by magnets on the train and the applied field creates a force moving the train forward.

 

Well that was quite good to know about maglev and its functioning but today my main concern was something much similar to this another new technology that has entirely based upon magnetic levitation .

What if I ask you to imagine a glowing bulb without wire more like that in move x men the evolution of wolverine ..?

Well no mind controls that bulb also works on magnetic levitation commonly know as flyte .

Screwing lights into a socket is so 2015. In the future, all the cool kids will deck out their space apartments with LED bulbs that float in midair. That might sound a little far-fetched at first, but once you take a look at Flyte it suddenly doesn’t seem so unbelievable.

Recently launched on Kickstarter, Flyte is a wirelessly powered light that hovers in the air by way of magnetic levitation. It is also completely contactless and draws power wirelessly from the charger block it hovers above.

Yes flyte an air floating light , so when you open up the box you would see a normal led bulb a wooden box a few plugs and a wire in that and that is very simple to operate all you need to do is connect the wire and plugs to the electric supply and off course   to the board as well then try to held the bulb over the board till it settles to its perfect position then leave it you will actually find it floating now just tap on the wooden block any where and you can clearly  observe that bulb glowing .

That was actually how you could use it which was quite handy I guess .

But our main concern is about the how factor of the whole invention …

So lets now discuss how it really works …

The Flyte works on the same principles as a Maglev train, with the opposing forces of magnets (built into both the bulb and the wooden base) counteracting the downward pull of gravity. Meanwhile, the magnets in the wooden block also wirelessly power the bulb. If this all sounds complicated, rest assured that setting up the Flyte is simple: gently lower the bulb over the centre of the base until you feel a slight resistance, then – hey presto – the magnets will hold it in place.

The Flyte’s bulb, on the other hand, is powered through a process called induction, wherein an electromagnet with a current flowing through it can generate a current in another body placed nearby. For instance, an induction hob in a kitchen creates an electromagnetic field which, when in contact with magnetic material like an iron pan, transfers or “induces” energy into the metal and heats food.  In the case of the Flyte, the coil of magnets in the wooden base – which plugs into your mains – heats the coil in the bulb while floating in the base’s electromagnetic field.

If you think the Flyte sounds like a bright idea, be aware you would actually struggle to read by it’s light. It has a maximum brightness of 60 lumens, which is much lower than the 450 lumens given off by a standard 40W bulb.  However, the bulb is built to last and will glow for 50,000 hours, which works out as 11 years if you use it for 12 hours a day, or 22 if you only use it for six hours a day.

So for me the technology is new quite handy but just for fancy use unlike other maglev inventions like maglev train .and that’s why this isn’t that popular among public .

So keep learning ..

Keep innovating …

TOP 5 BREAKTHROUGH TECHNOLOGIES OF 2018

Published

dueling rival neural networks
the top 5 breakthrough technologies in 2018

Here is look at top 5 breakthrough technologies from 2018 that will create revolution. 3-d metal printing, artificial embryos, dueling neural networks, babel-fish earbuds and much more…

1. 3-D Metal Printing

3d metal printing applications in the automotive industry

Metal 3-D Printing holds a unique position in modern-day product development. The technology can create lighter, stronger parts, and complex shapes that aren’t possible with conventional metal fabrication methods. It facilitates tooling for conventional manufacturing technologies, reducing costs and lead times. It can also provide more precise control of the microstructure of metals. In 2017, researchers from the Lawrence Livermore National Laboratory announced they had developed a 3-D-printing method for creating stainless-steel parts twice as strong as traditionally made ones. 

Also in 2017, 3-D-printing company Markforged, a small startup based outside Boston, released the first 3-D metal printer for under $100,000.

Another Boston-area startup, Desktop Metal, began to ship its first metal prototyping machines in December 2017. It plans to begin selling larger machines, designed for manufacturing, that are 100 times faster than older metal printing methods.

The printing of metal parts is also getting easier. Desktop Metal now offers software that generates designs ready for 3-D printing. Users tell the program the specs of the object they want to print, and the software produces a computer model suitable for printing.   

2. Artificial Embryos

In a breakthrough that redefines how life can be created, embryologists working at the University of Cambridge in the UK have grown realistic-looking mouse embryos using only stem cells. No egg. No sperm. Just cells plucked from another embryo.

Synthetic human embryos would be a boon to scientists, letting them tease apart events early in development. And since such embryos start with easily manipulated stem cells, labs will be able to employ a full range of tools, such as gene editing, to investigate them as they grow.

Artificial embryos, however, pose ethical questions. What if they turn out to be indistinguishable from real embryos? How long can they be grown in the lab before they feel pain? We need to address those questions before the science races ahead much further, bioethicists say.

3. AI for Everybody

AI for everybody

Artificial intelligence has so far been mainly the plaything of big tech companies like Amazon, Baidu, Google, and Microsoft, as well as some startups. For many other companies and parts of the economy, AI systems are too expensive and too difficult to implement fully.

What’s the solution? Machine-learning tools based in the cloud are bringing AI to a far broader audience. These products will be essential if the AI revolution is going to spread more broadly through different parts of the economy.

Currently AI is used mostly in the tech industry, where it has created efficiencies and produced new products and services. But many other businesses and industries have struggled to take advantage of the advances in artificial intelligence. Sectors such as medicine, manufacturing, and energy could also be transformed if they were able to implement the technology more fully, with a huge boost to economic productivity.

4. Dueling Neural Networks

Artificial intelligence is getting very good at identifying things: show it a million pictures, and it can tell you with uncanny accuracy which ones depict a pedestrian crossing a street. But AI is hopeless at generating images of pedestrians by itself. If it could do that, it would be able to create gobs of realistic but synthetic pictures depicting pedestrians in various settings, which a self-driving car could use to train itself without ever going out on the road.

The problem is, creating something entirely new requires imaginationand until now that has perplexed AIs.

The solution first occurred to Ian Goodfellow, then a PhD student at the University of Montreal, during an academic argument in a bar in 2014. The approach, known as a generative adversarial network, or GAN, takes two neural networksthe simplified mathematical models of the human brain that underpin most modern machine learningand pits them against each other in a digital cat-and-mouse game.

Both networks are trained on the same data set. One, known as the generator, is tasked with creating variations on images it’s already seenperhaps a picture of a pedestrian with an extra arm. The second, known as the discriminator, is asked to identify whether the example it sees is like the images it has been trained on or a fake produced by the generatorbasically, is that three-armed person likely to be real?

Over time, the generator can become so good at producing images that the discriminator can’t spot fakes. Essentially, the generator has been taught to recognize, and then create, realistic-looking images of pedestrians.

The technology has become one of the most promising advances in AI in the past decade, able to help machines produce results that fool even humans.

 

5. Babel-Fish Earbuds

pixel earbuds for automatic language transalation

In the cult sci-fi classic The Hitchhiker’s Guide to the Galaxy, you slide a yellow Babel fish into your ear to get translations in an instant. In the real world, Google has come up with an interim solution: a $159 pair of earbuds, called Pixel Buds. These work with its Pixel smartphones and Google Translate app to produce practically real-time translation.

Google Translate already has a conversation feature, and its iOS and Android apps let two users speak as it automatically figures out what languages they’re using and then translates them. But background noise can make it hard for the app to understand what people are saying, and also to figure out when one person has stopped speaking and it’s time to start translating.

Pixel Buds get around these problems because the wearer taps and holds a finger on the right earbud while talking. Splitting the interaction between the phone and the earbuds gives each person control of a microphone and helps the speakers maintain eye contact, since they’re not trying to pass a phone back and forth.

Qualcomm unveils Snapdragon 675 with new Kryo 460 CPU

Published

on

Qualcomm Technologies, Inc. is continuing to bring together global manufacturers and operators, along with software and hardware technology vendors, to strategize and discuss industry trends and technology developments with their Snapdragon chipsets. Mark your calendars for this 3-day event highlighting 5G, connectivity, AI, IoT and so much more. This year’s summit promises to be one of the best ever, featuring wireless leader keynotes, breakout sessions, multiple exhibits and networking events, all showcasing the latest technology, and much more. Qualcomm made a lot of advancements in the last few months. And the tech giant made steady announcements at their 4G/5G Summit at Hong Kong.

Qualcomm 4G/5G Summit at Hong Kong

In the Keynote, Qualcomm’s President Mr. Cristiano Amon talks about how 5G is nearing deployment, with global trials underway and deployments planned in the coming months. He continues about how the next generation of wireless will allow virtually every industry to deliver advanced connectivity and increased intelligence across the rapidly evolving wireless edge. It is essential that the broader ecosystem pursues the wireless and computing technologies that will provide the foundation for the coming transformation. To just have an overview read to it, focus on the key points as per Qualcomm:

  • Qualcomm optimized the Snapdragon 675 for mainstream use.

  • The first smartphones using the Snapdragon 675 will ship in Q1 2019.

  • The Snapdragon 675 is Qualcomm’s third mid-range processor announced within the past six months.

Overview

Qualcomm makes one of the finest processors in the industry and as it turns out they also focus on the mid-range consumers. It comes out on the top with the 710 followed by the 670 in the mid-range category. Now that it is history, Qualcomm announced a new processor in the 600 range. The Snapdragon 675 is a really interesting processor but not for all the reasons you are thinking. In terms of where it fits in the overall Qualcomm’s mid-range processor, is somewhat between the 670 and the 710. And for a little humor, the Snapdragon 675 has got a slightly worse Adreno 612 GPU in it compared to the 615. The Snapdragon 675 has got the same modem as the 670, the exact DSPs and the image processors, but with a bit of enhancement.

Qualcomm 675 chipset launched

So, why is the Snapdragon 675 so interesting? Well, it is using the 4th Generation Kryo 460 CPU Design. And as per our research and Qualcomm’s announcement, no other processor in its lineup uses the 4th Gen CPU. Well, the Kryo core 1st Gen design is found in-house in the Snapdragon 820 and 821. Then the 2nd Gen Kryo which was built with the Cortex technology is found in the Snapdragon 835 and finally, the 3rd Gen is found in Snapdragon 845.

Snapdragon 675 + 4th Gen Kryo Core

Snapdragon 675 is basically a Cortex A76 coupled together with a Cortex A55. This new Architecture built on ARM Cortex offers a 20% overall performance improvement, optimized across 2 performance and 6 efficiency cores. So Qualcomm is using the 4th Gen with this 6+2 configuration. So it still is an Octa-core chipset but with 2 cores dedicated for higher stability and results and 6 for better power efficiency. So, more interestingly,  what this tells us is that the next 800 series will be using the 4th Gen Kryo.

The 675 is not only filled with upgrades. For example, the 675 is constructed with an 11nm process whereas the Snapdragon 670 had a 10nm process. The GPU has been downgraded from an Adreno 615 to an Adreno 612, too. With that said, Qualcomm assured us that the Snapdragon 675 performs considerably better than the Snapdragon 670. With built-in game enhancements, for example, reduce “janks” or stutters by over 90 percent during gameplay.

The Comparison of Snapdragon(s)

So let’s look at the rest of the Snapdragon 675 and detail out how it differentiates from the 670 and the 710 chipsets. So as you can see all the 3 processors use the 6+2 setup. The performance core gets a boost with the A76 instead of the A75. When it comes to GPU the 675 lags behind and as it turns out the 710 has got the best GPU. But as per Qualcomm, they have been tweaking it for a better gaming performance. The differences which can only be pointed out when we will receive a device. It supports the LPDDR4X where the X stands for even more power efficient than the standard LPDDR4.

Now that they all showcase the same DSPs across is a good thing. With the 250L, it gets the 480fps HD Slo-Mo that will pump-up any camera. The modem is exactly the same as the rest. It’s like Qualcomm didn’t even bother making an upgrade to it. Focusing on the important part, the 675 uses Samsung’s fabrication process. So, this will be built by the looks of it exclusively on Samsung’s fabrication plans.

Qualcomm’s Worse is actually Better

So coming back to the GPU here, the 675 boasts an Adreno 612 instead of a 615 or a 616 on its brothers. Qualcomm is actually saying that they have heavily optimized the gaming performance. This does mean that the overall performance will be better as compared to the rest. Qualcomm also suggests that on a list of particular games that they tried, this performs much better. They get 90% less ‘JANKS’, whatever that means.

gaming on snapdragon 675 chipset, qualcomm

It might get a better user experience while gaming. Qualcomm is known to make certain tweaks for a better gaming performance and experience. The list of games does suggest that it focuses on a great diversity of games. This is actually good stuff from Qualcomm. Qualcomm also states that it works closely with both mobile game and game engine developers to improve the gaming UX on Android, though this isn’t unexpected given how they’ve collaborated with game studios such as NetMarble for Snapdragon flagship chip releases in recent years.

Gaming enhancement on snapdragon 675

Although that the 600 range continues to be very strong with support for 6 cameras, 3 on the front and 3 on the back. So everything from super-res zoom to telephoto capture to specialized Bokeh mode is now available on the 675. So there’s a bunch of things that Qualcomm has put into their processors that make them very useful. They did a great deal of work for the mid-range smartphones. Expecting really strong developments from the manufacturers now. That’s it for now.
