Huawei to launch first 5G smartphone by mid 2019

At its Global Analyst Summit 2018 in Shenzhen,China, Huawei detailed its plans to release its first 5G-enabled smartphone in the second half of 2019.

Huawei aims outsmart it's western counterparts in 5G roll out revealing plans to launch a handset next year packing the firm’s very own 5G modem.

Huawei recently revealed the Balong 5G01 chip in February at MWC 2018, in Barcelona. The company claims the model is capable of 2.3Gbps bandwidth.

This particular model is designed for mobile hotspots and self-driving cars. However, it is also working on modems exclusively for use in 5G smartphone.

Huawei’s 5G NR products have passed TÜV SÜD's (the European Union's certification authority) strict verification requirements after several rounds of rigorous testing and evaluation. As a leading information and communications technology (ICT) solutions provider, Huawei is now the first company to achieve a CE type examination certificate (TEC) for its 5G products.

If Tech rumors are correct, first 5G handset would be from Huawei mate series.

5G handset from other manufactures

Samsung signed a strategic agreement with Qualcomm that covered the “transition to 5G".This tells that Samsung is also keen on 5G hansets.Samsung had previously earmarked 2019 for its first 5G handsets. Qualcomm already has its own modem called the X50 for mobile devices recently managed to hit speeds of 4.51 gigabits per second.

Intel announced a partnership with Microsoft, Dell, HP, and Lenovo to create 5G-enabled laptops based on Intel's own modems.

5G handset challenges

  • Building a 5G smartphone is more challenging than 3G or 4G as these will include multi-modes (2G,3G,4G,4.9G, 5G SA/NSA).Packing multiple antennas and chipsets into a single device is tough and challenging.
  • 5G uses Millimeter wave bands (26, 28, 38, and 60 GHz)., which makes the RF integration and positioning more complicated.Designing boards  for RF is challenging.
  • 5G network data speed will be 1-10Gb. 5G phone needs 5x more processing power and 2.5x more power consumption.Currently available batteries are not a good choice for 5 handsets.

IBM creates ‘world’s smallest computer’ that’s smaller than a grain of salt

Recently during IBM Think 2018, the company's flagship conference, IBM unveiled what it claims is the world's smallest computer.The finished computer is smaller than a grain of salt.First of all let me tell you this tiny device is not for PC or smartphone.It has got some specific applications.
Left: 64 motherboards with two tiny computers in the top-left corner. Right: The tiny computer, mounted to a motherboard, atop a pile of salt. IBM
How much computing power tiny chip is embedded with?
It has the same computing power as Intel’s X86 chip from the 90s.It contains around million transistors.You may be wondering what we are going to do with such a small computing power.There comes the blockchain.

Architecture of IBM's world's smallest computer

IBM’s new computer, contains up to 1 million transistors, along with a small amount of static random access memory(RAM), a light-emitting diode (LED) and photo-detector that allow it to communicate, and an integrated photovoltaic(Solar cell) cell for power.
System architecture of IBM's tiny computer
How much it would cost?
IBM claims that it is “small enough and cheap enough to be put anywhere—and everywhere.”
The computer will cost less than 0.10$ to manufacture.On mass production it will reduce further.

Applications and uses of IBM's tiny computer

According to the company, the device will be a data source for anti-fraud blockchain applications.
Block chain is nothing but distributed decentralized database/Ledger that is nearly impossible to tamper.Blockchain became popular with bitcoin and cryptocurrencies. Specifically, this computer will be a data source for blockchain applications. It's intended to help track the shipment of goods and detect theft, fraud, and non-compliance.It can also do basic AI tasks, such as sorting the data it's given.

"Within the next five years, cryptographic anchors — such as ink dots or tiny computers smaller than a grain of salt — will be embedded in everyday objects and devices. They’ll be used in tandem with blockchain’s distributed ledger technology to ensure an object’s authenticity from its point of origin to when it reaches the hands of the customer. These technologies pave the way for new solutions that tackle food safety, authenticity of manufactured components, genetically modified products, identification of counterfeit objects and provenance of luxury goods".says IBM head of research Arvind Krishna.

micro-LED: Display Technology that can revolutionize our viewing experience

micro-LED latest display technolgy:What is it? What are it's advantages and disadvantages and current trends

samsung's microLED modular TV The Wall

Content Highlights
  • Structure of LED panel displays
  • LCD,LED,OLED and mLED
  • Structure of a microLED
  • Pros and Cons of micro-LED technology
  • Current trend in micro-LED 

MicroLED is the latest in he emerging display technologies .Starting from CRT, through LCD,LED ,OLED and mLED, display technology is evolving at higher speed. mLED displays consist of arrays of microscopic LEDs forming the individual pixel elements. It has got lot of advantages over other existing display technologies.

Micro LED was first realised by in the year 2000 by a research group run by Prof. Hongxing Jiang and Prof. Jingyu Lin of the Texas Tech University.

Let us recall the basic structure of LED display.
An LED display is a flat panel display, which uses an array of light-emitting diodes as pixels for a video/picture display.As you know an LED( light-emitting diode) is a p-n junction which emits light when electric current is passed through it.In an LED dispaly panel , these LEDs are shrunk down dramatically and arranged in red, green and blue clusters to create an individual pixel that can reproduce white light and various colors.

LED V/s LED back-lit LCD V/s OLED V/s micro-LED

LED displays are used in large displays like leaderboards,advertising pannels etcc.  LED TVs and Smartphones displays are usually LCD with LED back-light. Usually consumers think that LED TVs have LED display. It is LED backlit LCD. But, OLED and micro-LED ae self illuminating.

In an OLED(Organic Light Emitting Diode), a thin layer of organic material is placed between two conductors, which is then used to produce light when a current is applied.At least one of these electrodes is transparent.Properties of these organic material is analogous to semiconductors.

Micro-LED isn't a new display technology, this technology is a solution to the problem faced by panel manufacturers.It helped them to mass transfer and bond million of tiny LEDs in a minimum area.Individual micro-LEDs usually ranges from 1 to 10 μm, and are transferred in large volumes onto the display substrate.

Structure of a single  µLED 

structure of micro LED
microLED light extracting structure(image courtesy infiniled )
MicroLED (µLED) is formed by the integration of light control elements directly with light producing source. This optical component results in a high extraction efficiency and all the light exiting through a single surface of the LEDs.The MicroLED ( µLED) is optimised for flip-chip mounting. This results in excellent heat-sinking of the device and reduced thermal effects in the light source.
conventional LED vs microLED
conventional LED Die Vs µLED
Above design was patented by infiLED later acquired by Oculus. In their design parabolic reflectors collimates the light and directs it through a single surface of the device. Larger illumination areas can be obtained by densely packing and filling a die with the parabolic structures, effectively giving a MicroLED cluster or LED with all the pixels working in concert.

 Advantages of micro-LED over TFT-LCD and OLED displays

-High contrast ratio. In backlit TFT-LCD panels complete black is not possible.Black is represented by dark grey only. This is because back-light cannot be switched off it completely. But microLED is self illuminating. So pure black can be obtained by switching off the individual micro-LED. This is one of the main advantage of micro-LED displays.

-Improved brightness to power (lux/W) efficiency, meaning that the same panel brightness can be achieved for lower power.Power consumption can be 90 percent lower than LCD and up to 50 percent lower than OLED

-Micro-LED displays will also offer a longer lifespan than current OLED panels. Lifespan of the organic materials used to make the blue OLED is limited.

-Higer resolution in compact form and higher PPI. This makes them perfect for smartphones and VR displays

-High response times in the ns (microsecond) range.This feature make them suitable for VR headsets.

-Suitable for flexible displays.It's tiny structure can be deposited on a flexible substrate to form flexible display panels. Unlike TFT-LCD and OLED , damage would be minimum on bending or rolling.

Disadvantages of micro-LED pannels

-Micro-LED panels are expected to be considerably more expensive, possibly three to four times higher than current LCD and OLED panels.This will fall in time, but it will slow down the investments.

Current trends in micro-LED panels

2010 onwards , manufacturers are aggressively behind micro-LED display technology R&D. Manufacturers leading in micro-LED patent applications include Apple affiliated Luxvue, Mikro Mesa, Sony, Leti and others.
-Sony launched its 55-inch “Crystal LED Display” in 2012, a new micro LED display technology utilizing Full HD Resolution. The display uses about 6.22 million micro LEDs
-Samsung unveiled its first MicroLED TV at CES 2018, the 146-inch "The Wall" 4K TV.
Commercial launch of large microLED panels would take some time since manufactures have to limit the cost within a limit to make it suitable for consumer electronic devices.
-Mass transfer is a critical technology for Micro LED manufacturing, transferring Micro LED to a target backplane quickly and accurately will be one of the topics that manufacturers need to work on the most.

Content Highlights
  • First bendable e-paper (Gyricon)
  • Samsung bendable smartphone
  • Samsung Galaxy X  rumors 
  • LG flexible display
  • Apple's patent application for flexible display concept
  • Lenovo bendable phone CPlus
  • ITRI and BOE flexible display prototypes

Every smartphone lover is waiting for a smartphone that can be folded or rolled like paper.Let us have check at how long we have to wait for such a product.

First Flexible Display

Flexible electronic paper (e-paper) based displays were the first flexible displays conceptualized and prototyped. This form of flexible displays has a long history.Many companies attempted but failed to design slated for mass production that can be used in consumer electronics. One of the notable among such prototypes was Gyricon put forth by Xerox PARC. Still mass production of e-paper  is expensive.
Gyricon flexible e-paper
flexible e-paper

How Gyricon e-paper works?

Gyricon contains a lots of small spherical beads, sandwiched in between two thin transparent plastic sheet.The beads, each contained in an oil-filled cavity, are free to rotate within those cavities. The beads are "bichromal", with hemispheres of two contrasting colours (e.g. black and white, red and white).  Each side of the bead has  electrical charge (positive or negative), so they exhibit an electrical dipole. When voltage is applied to the surface of the sheet, the beads rotate to present one coloured side to the viewer. Voltages can be applied to the surface to create images such as text and picture.
Cross section of Gyricon flexible e-paper
Gyricon cross section
 They remain fixed in position until another electrical charge is applied to change the orientation of the beads. So, there is no need of power after text/picture is written.This e-paper can be erased and rewrite infinite time(theoretically) by applying corresponding voltages.

Current trends in flexible and foldable displays 

Recently  flexible display market has gained great momentum owing to the competition and usage in various areas likes mobile phones, laptops and other handheld consumer electronic devices. Due to the advent of advanced materials and new technologies, display market is evolving at higher speed.

  • Iris Scanning Vs Retinal Scaanning

Besides fingerprint and facial recognition, eye scanning is one of the widely used biometric identification. Iris recognition retinal scanning are the two types of eye recognition method.Iris recognition is a method of biometric identification that uses mathematical pattern-recognition techniques on images of one or both of the irises of an individual's eyes. complex Iris pattern of each person is unique, stable, and can be seen from some distance. Latest smartphones like Samsung Galaxy S8 comes with inbuilt Iris recognition for added security.

What is Iris

The iris is a thin, circular structure in the eye, responsible for controlling the size of the pupils and thus the amount of light reaching the retina. The color of the iris defines the eye color.

How Iris scanning and recognition is done

An automated iris recognition system can be subdivided in to 3 major parts:-¨ 

1.Image acquisition : To acquire image of iris with sufficient resolution .Image acquisition is done by either a digital camera or NIR(Near Infrared) camera.

2.Iris Localization: To delemit the iris from the rest of the image. When the camera takes a picture, the computer locates: The center of the pupil
  • The edge of the pupil
  • The edge of the iris
  • The eyelids and eyelashes
System will exclude eyelids, eyelashes, and specular reflections that often block parts of the iris.
After localization image will only contain pixels of Iris.

But images of Iris captured under different light intensity will not be the same. When eye is exposed to more light pupil will contract with the help of Iris and at low light pupil will be dilated.

This problem is addressed by a normalization method known as rubber sheet model.This model was developed by Daugman ,a professor at Harvard university. In simple words , this normalization procedure converts a circular shape (Iris) image into rectangular shape. Technically speaking a mathematical tansform is applied on the image to transform it from polar coordinates to Cartesian coordinates.

3.Pattern matching: The Iris pattern derived from this process is compared with previously stored template.

Advantages and disadvantages of Iris recognition

The iris of the eye has been described as the ideal part of the human body for biometric identification for several reasons.It has got many advantages over other biometric recognition like fingerprint matching, retina scanning, vein recognition etc..

Advantages of Iris scanning and recognition

  • It is an internal organ that is well protected against damage and wear by a highly transparent and sensitive membrane (the cornea). This distinguishes it from fingerprints, which can be difficult to recognize after years of certain types of manual labor.
  • Even genetically identical individuals (and the left and right eyes of the same individual) have completely independent iris textures
  • Non-invasive: An iris scan is similar to taking a photograph and can be performed from about 10 cm to a few meters away. Illumination source is normal light or low energy infrared which is not harmful to human eyes. Retina scan is more invasive than iris scan.’’
  • Iris recognition works with clear contact lenses, eyeglasses, and non-mirrored sunglasses.

Disadvantages of iris scanners

  • Many commercial iris scanners can be easily fooled by a high quality image of an iris or face in place of the real thing.
  • The accuracy of scanners can be affected by changes in lighting. Iris scanners are significantly more expensive than some other forms of biometrics
  • Modern cataract surgery can cause change iris texture in such a way that iris pattern recognition is no longer feasible or the probability of falsely rejected subjects is increased.

Iris scan vs Retina scan

Similarities
Iris and retinal scanning are known as “ocular-based” identification technologies, meaning they rely on unique physiological characteristics of the eye to identify an individual.
Differences
In retina scanner a infrared beam is projected into the eyes and reflected beam is used to construct the structure of retina.Unlike retina scanning, iris recognition uses camera technology with subtle infrared illumination to acquire images of the detail-rich, intricate structures of the iris.In retina scanning device need to be very close to the eyes.But ,since iris is visible outside the body camera need to placed at a distance up to 10 inches.

How does retinal scanning works

How does a retinal scanner works?

retina scanner
A retinal scan relies on unique physiological characteristics of the eye to identify an individual
Retinal scanning is one of the most well-known biometric technologies. A retinal scan relies on unique physiological characteristics of the eye to identify an individual. Before we go into the working of retina scanner let us have a look at what is retina

What is retina?

The retina is a thin tissue composed of neural cells and thin blood vessels that is located in the posterior portion of the eye. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
retina scan
Human eye structure
Because of the complex structure of the capillaries that supply the retina with blood, each person's retina is unique. The network of blood vessels in the retina is not entirely genetically dictated. Even identical twins do not share a similar retinal pattern. Retinal biometric exploits this uniqueness.

Working of a retinal scanner

A retinal scan is performed by projecting a beam of low-energy infrared light into a person’s eye as they look through the scanner’s eyepiece This infrared light beam traces a circular path on the retina at the back of the eye. The blood-filled capillaries absorb more of the infrared light than the surrounding tissue. Because of this, there is a variation in the intensity of the reflection.

Instead of storing complete image ,the scanner measures this reflection at difference points along the beam path.
retina scan image
Image of retina and blood vessels
A standard scanner measures reflection at 320 points. It then assigns an intensity grade between zero and 4,095. The resulting numbers are compressed into an 80-byte computer code and stored in data base.We have already seen that retina blood vessel pattern of each person is unique. So chances of spoofing is so little.

Retina scan vs iris scan

Retina scanning is often confused with iris recognition. Even though both rely on unique physiological attributes of the eye to identify an individual,there are certain differences in the way they work.

The iris is a thin, circular structure in the eye, responsible for controlling the size of the pupils and thus the amount of light reaching the retina. The color of the iris defines the eye color.

Iris Recognition uses a camera, which is similar to any digital camera(NIR:Near InfraRed camera), to capture an image of the Iris.

Iris scanner uses mathematical pattern-recognition techniques on images of the irises of an individual’s eyes, whose complex random patterns are unique and can be seen from some distance.

Nowadays iris scan is preferred over retina scan due to its advantages. While the accuracy of retina scan can be affected by diseases; the iris texture remains extremely stable because it is internal and protected, yet externally visible part of the eye.

Retinal scanning advantages and disadvantages

Advantages:
  • Less tampered: Since iris is inside our body chances of tampering is very less.
  • Less chances of theft since it is always inside your body.
  • High accuracy: error rate is one in million
  • Speedy results: Identity of the subject is verified very quickly.
  • They do not require as much computer memory as other biometrics like fingerprint scan, voice recognition etc..
Disadvantages:
  • Invasive:Retina scan requires a very close encounter with the scanning device by using a beam of light deep inside the eye which is considered to be invasive and this may leads to eye problems.
  • Measurement accuracy can be affected by a disease such as cataracts, severe astigmatism
  • Retinal patterns may be altered in cases of diabetes, glaucoma or retinal degenerative disorders,
  • High equipment cost

Application and uses of retinal scanning

Retinal scan security systems: Retinal scanners are typically used for authentication and identification purposes.It is used by several government agencies including the FBI, CIA, and NASA.. Retinal scanning has been used in prisons, for ATM identity verification

Medical application: Retinography or retinal scanning also has medical applications. Communicable illnesses such as AIDS, syphilis, malaria, chicken pox well as hereditary diseases like leukemia, lymphoma, and sickle cell anemia impact the eyes. Pregnancy also affects the eyes. Likewise, indications of chronic health conditions such as congestive heart failure, atherosclerosis, and cholesterol issues first appear in the eyes.

Protect your personal data:Retina scanner phones and Iris scanner phones are already out there in the market. Most of the leading smartphone companies like apple,Samsung,Microsoft prefer iris scan over retina scan.Many app builders are also coming with retina scanner for android. But reliability of such applications are quiet doubtful.

    Finally much sweeter android 8.0 is out.Android 8.0 Oreo follows Android 7.1.2 Nougat, and it continues Google’s tradition of alphabetically naming its version updates after desserts.Every smartphone enthusiast will be eager to know the new features of Android 8.0 Oreo.
    Android 8.0 Oreo Mascot
    Android 8.0 doesn't have much visible overhauls from it's predecessors.But there are plenty of new useful features.These small small changes make Android version 8.0 an update you don’t want to miss.

    2x faster booting

    Google claims that boot time of Android 8.0 Oreo OS is 2x faster than its predecessors.Get started on your favorite tasks more quickly when powering up.

    Autofill

    Account creation, login, and credit card transactions take time and are prone to errors. Users can easily get frustrated with apps that require these types of repetitive tasks.With your permission, Autofill remembers your logins to get you into your favorite apps at supersonic speed.Think of Google Chrome browser’s autofill option, where it stores your login information or address, and allows you to easily add it into forms.

    Smart Text selection

    Smart Text Selection is also one of those features you won’t appreciate until you use it. We’ve all had to copy an address or phone number from one app, and then open the corresponding app such as Google Maps or your phone dialer to paste it in. Now with Smart Text Selection, when you highlight a phone number, for example, you’ll get the option to jump into the dialer app immediately.

    Picture-in-Picture

    Android 8.0 allows activities to launch in picture-in-picture (PIP) mode. PIP is a special type of multi-window mode mostly used for video playback.

    Suppose you are watching your favourite YouTube videos and you want to text your friend without interrupting.This feature it lets you continue watching a YouTube video or a video call when you exit the app. The video now acts like a floating pop-up over the home screen or other app you’re using, allowing you to multitask.

    Notification

    Biggest change in Android 8.0 Oreo that a user will experience is it's redesigned notification behavior and settings.
    • Notification Dots:Press the notification dots to quickly see what's new, and easily clear them by swiping away.
    Android 8.0 provided innovative notification control feture
    • Notification channels: Android 8.0 introduces notification channels(notification categories) that allows user to customize each type of notification you want to display.This feature brings more control over what notifications you see. Press and hold a notification, and you can see a toggle to block all notifications from an app.
    • Notification Snoozing: Users can snooze notifications, which causes them to disappear for a period of time before reappearing.

    Google Play Protect

    Working to keep your device and data safe from misbehaving apps by scanning over 50 billion apps per day, even the ones you haven't installed yet!Even installing apps from outside the Play Store is now a little more secure. If you go to Settings > Security > Google Play Protect, it will tell you when it last checked your app and device for “harmful behavior.”

    Better battery back up

    Whether you're talking, playing, working or streaming, you can feel confident about keeping your battery strong and full of life.Features like Background Location Limits,Background Execution Limits etc.. make this possible.
    • Background Location Limits:In an effort to reduce power consumption, Android 8.0 (API level 26) limits how frequently background apps can retrieve the user's current location. Apps can receive location updates only a few times each hour.
    • Background execution limits:Whenever an app runs in the background, it consumes some of the device's limited resources, like RAM. This can result in an impaired user experience, especially if the user is using a resource-intensive app, such as playing a game or watching video. To improve the user experience, Android 8.0 Oreo imposes limitations on what apps can do while running in the background.

    New Emojis

    Downloadable fonts

    Applications no longer need to bundle custom fonts, which helps reduce their size.Fonts can be downloaded and installed separately.

    Wi-Fi Aware

    Android 8.0 adds support for Wi-Fi Aware.On devices with the appropriate Wi-Fi Aware hardware, apps and nearby devices can discover and communicate over Wi-Fi without an Internet access point.

    Pointer capture

    Some apps, such as games, remote desktop, and virtualization clients, greatly benefit from getting control over the mouse pointer. Pointer capture is a new feature in Android 8.0  that provides such control by delivering all mouse events to a focused view in your app.

    Integrated printing support

    Android8.0 comes with inbuilt printer support.Android Oreo devices will be compatible with all Mopria-certified printers, which make up 97% of printers sold worldwide.

    Project Treble

    The biggest change to the foundations of Android to date: a modular architecture that makes it easier and faster for hardware makers to deliver Android updates.

    Android 7.0 Nougat’s release in August 2016, the version is only installed on 13.5 percent of Android devices. iOS 10, on the other hand, is installed on 86 percent of devices. When Google rolls out an update, chipmakers, manufacturers, and carriers all need to test it out to make sure nothing breaks, and this process can take months, if not more.Project Treble attempts to mitigate the issue by separating the Android code to make it easier for chipmakers like Qualcomm to find and make sure the software works with its processors.
