Moto G4 Plus First Impressions

Moto G Series Smartphone Enters its Fourth Generation

Lenovo which tends to own the smartphone business of Motorola seems to be getting stronger and the formerly Google owned company is sticking to its main philosophy. The focus is on the Moto G series of smartphone that has entered its fourth generation and which is named `Moto G’ with references to the generation of the device like Moto G 2015 or Moto G 3rd Generation. The complete line-up, in fact is being broken down further and Lenovo is launching the Moto G4 Plus in India, soon while the Moto G4 would be coming in June.

The Moto G4 Plus is Motorola accepting some of the market developments though sticking to its own philosophy. It has a 5.5 inch 1080p display, a clear update from the 720p displays seen against the original Moto G. In Moto G4 Plus the colours do not pop and it is also a bitreflective. The most important update is the camera which has a 16Mp shooter on the back with laser auto-focus as well as PDAF and it has been claimed by Motorola that it is better than the iPhone 6 Plus. However, there is a considerable amount of processing time and the camera app launches slower than the older Moto G phones.

Moto G4 Plus – Two Options

This could be due to its added features such as HDR, Pro Mode and best shot that tends to make the app heavier. The lighting during the launch event was not suitable to take good shots but served to satisfy several users, at least in the sunlight. Motorola has utilised an Omnivision sensor for this smartphone. Besides this, another addition is the fingerprint sensor that does not make it to the Moto G4.

 Located on the front, the fingerprint sensor on the Moto G4 Plus is said to be square shaped and tends to feel new if not odd. It seems to have ridged design that feel unnatural and though it is not a button, it could be used to light up the screen or close an app. In India, the Moto G4 Plus comes in two options, for the version with 16GB internal storage and 2GB RAM forRs 13,499 and for 32GB internal storage and 3GB RAM for Rs 14,999.

Android 6.0.1 Marshmallow Operating System

The processor is the same for both options which has the Qualcomm Snapdragon 617 oct-core chip. Each model comes with a MicroSD card slot which can have an extra 128GB of additional storage in order that the added internal memory may not be a big concern. Beneath the screen lies the fingerprint sensor having an unusual square shape design. The operating system running on the device is Android 6.0.1 Marshmallow which in line with the promise of Motorola, seems to be most prevailing version available.

It also has a battery of 3,000mAh. A lot of specification is shared between the Moto G4 and the G4 Plus comprising of the 5.5 inch screen with 1080p resolution, a Snapdragon 617 processor together with a fast charging 3,000mAh battery while the Android version tends to remain the same together with the microSD card slot.

Google built a tiny radar system into a smartwatch for gesture controls

Google’s Tiny Radar Chips in Electronics – Controlling Digital World

In a conference room at an important tech corporation like Google, Ivan Poupyrey who works at Google’s ATAP research lab had posed a question on `How are you going to interact with an invisible computer? Poupyrey a technical project lead for Project Soli which has been designed to prove that we can embed tiny radar chips in electronics so that minute hand gestures could be utilised in controlling the digital world around us.

Advanced Technologies and Projects – ATAP is a division within Google which is at crossroads. Formerly led by Regina Dugan of DARPA recognition together with her influence had led the division to stream technologies which would range from modular phones – Project Ara, to real time 3D mapping- Tango, to cinematic, live-action virtual reality movies – Spotlight Stories.

Earlier in the year she had left for Facebook and hence it was a question whether the project left behind by her would continue. Tango had progressed into Google while Ara seemed stuck in the muck. However, the Jacquard touch-sensitive fabric project together with the Soli is yet at ATAP whereas Soli has at least a new and a remarkable goal, creating the industry as well as the project language for radar-enabled consumer electronics.

Radar to Work in SmartWatch

For this reason, Poupyrey had engaged his team to prepare for more than just experiment so as to ascertain that radar can work in a smart watch. Poupyrey had commented that if one can put something in a smartwatch, you could put it anywhere. So ATAP had redesigned the Soli chip in order to make it smaller and pull less power. It then redesigned it to do the same thing again and again.

Eventually according to Hakin Raja, lead hardware and production engineer of Soli, the team developed the smallest of the chips which is a tiny sliver one could balance on the pinky toenail, with four antennas which tend to offer full duplex communication in sending and receiving radar beeps. The first duplication of Soli shipped in a development kit, drew 1.2w of power while this one tends to draw 0.054 w x 22x reduction. But developing a chip which is small tends to have some setback. Radar had been designed to identify massive flying metal objects from miles away, not tiny millimetre movement from finger just inches away.

Logical to Convert Spatial Signal Radar into Temporal One

Till recently, no one was concerned about the power draw at this scale and no one had to deal with believing what the signal would look like when it had shrunk down. Lead research engineer for Soli is Jaime Lien and it is her task to tune the machine learning procedures which get hardwired in the chip. Her main understanding was that it was logical to convert the spatial signal radar provided into a temporal one, tends to make sense on a computer.

But the same was nothing when compared to noise pollution and one would run into these small scales. She portrayed a vast set of screenshots of all types of impenetrable noise which her processes need to locate signal and at these scales it seems impossible to do any kind of beam forming. Moreover the electrons running through the chip need to be accounted for.

Hybrid Hydrostatic Transmission Enables Robots with Human-Like Grace and Precision

Hydrostatic Transmission Combines Hydraulic/Pneumatic Lines

A new kind of hydrostatic transmission which combines hydraulic as well as pneumatic lines can precisely as well as safely drive robot arms, providing them with the delicacy essential to pick an egg without breaking it. This communication does not have any friction or play providing great precision for jobs like threading a sewing needle. The hybrid transmission had made it possible to split the number of bulky hydraulic lines which a complete hydraulic system requires. Robotic limbs could thus be lighter and smaller according to John P. Whitney, assistant professor of mechanical and industrial engineering at North-eastern University, who is leading the development of the transmission and also an associate research scientist at Disney Research.

Whitney together with his colleagues from Disney Research, the Catholic University of America and Carnegie Mellon University would be reporting on the new transmission as well as the upper body humanoid robot, built with it at the IEEE Conference on Robotics and Automation, ICRA 2016, on May 17 in Stockholm, Sweden. Co-author Jessica Hodgins, vice-president at Disney Research and a professor of robotics at the Carnegie Mellon had stated that `the communication provides the robot with incredibly smooth and fast motion as well as enabling life-like interaction with people and the handling of delicate objects.

Robot Remotely Controlled by Human Operator

She adds that presently, the robot is remotely controlled by human operator though the same level of mechanical performance, once the motions are automated would be expected. Whitney states that the robot joint would normally have two hydraulic cylinders, which are balanced against each other. However in the new design, the researchers have paired each water-filled cylinder instead with air-filled cylinder.

The pneumatic cylinder tends to assist as a constant force air-spring offering the required preload force enabling the joint to move in both directions with half the number of bulky hydraulic lines. The new transmission was used by the researchers to build a simple humanoid robot having two arms with stereo cameras placed in the head, streaming their video signal to an operator wearing a head mounted display. The arms have been coupled to a similar control figure, which is hidden behind a wall to permit the robot to be used for human-robot communication study.

Combination of Small Mass/High Speed/Accurate Motion

Whitney has mentioned that this technology has enabled them to build robot arms which are light, fast and dexterous and that they have an incredible life-like nature, providing a combination of small mass, high speed together with accurate motion not envisage earlier.

Together with Whitney and Hodgins, the research team had also included John Mars of Disney Research, who had developed the camera and head-mounted display system as well as Tianyao Chen, research assistant at The Catholic University of America, who had designed the robot arms at intern at Disney Research.

Robots utilising this technology are suitable for naturally accommodating and life-like interaction with people. On tele-operation, the low friction and the lack of play enables the transmission to devotedly transmit contact forces to the operator, offering a high reliability remote sense of touch.

Smart Home Speaker, VR system, Chat service from Google

Google’s Virtual Reality System/Chat Service

Google has come up with a new smart home speaker, known as Daydream a virtual-reality system and a chat service called Allo. Over 7,000 people would be attending the showcase of Google in Mountain View California and in an effort to overtake Apple, Google has been adding in some more features to the next version of its Android operating system, comprising of a security method which tends to enable one to encrypt specific files instead of the complete phone. In a shot at Amazon, the company had declared Google Home, an Internet-connected speaker which tends to listen to your voice commands to play music or to control lights as well as thermostats in the home.

It is significant of Amazon’s Echo and would be made available later in the year for an unexpected price. The chat service, in the meanwhile would be using the computers of Google to predict how one would prefer to respond saving the typing stress. Allo would be competing with the popular chat services like Facebook’s Messenger and WhatsApp which are also owned by Facebook. Google Home and Allo would be tapping into the computing ability of Google. Artificial intelligence, is a term used in describing efforts in developing software that acts and behaves like humans, has been a central point of Google for several years.

Android Powers 80% of World’s Smartphones

Development made in the field has assisted the search engine of Google in understanding the intent of the inquiries of people much faster and vastly improved the understanding and responsive of its voice recognition services. Reporters as well as bloggers from across the world are attending to make sure that whatever the company reveals will also be featured in pictures, stories and videos that will be delivered to the massive audience of consumers.

The three-day showcase tends to attract thousands of computer programmers, providing Google with an opportunity of convincing them on why they should design applications and other services which tend to work with its gadgets together with an array of software that include the Chrome Web browser as well as Android operating system for mobile devices. Android tends to power around 80% of the world’s smartphones, mainly since Google gives away the software for free to device manufacturers. Google can manage to do that since it designs Android to feature its search engine, maps together with other digital services, providing more opportunities to portray the digital ads which tend to generate most of its revenue.

Google – Distributing Guidelines for Latest Controller

Apple iPhone tends to carry more importance with affluent consumers and present features which Android tends to copy. Apple would be holding same conference in June to reveal its fall software plans.The entry of Google in the still-emerging field of virtual reality came two years back when it had revealed a cheap headset that was made of cardboard. The company is said to be poised to get more thoughtful considering far more sophisticated option available for sale.

Together with Daydream, other manufacturers comprising of Samsung, HTC and Huawei would have smartphones adept in handling it. These tend to be more comfortable and immersive than the cardboard headset. Google would also be distributing guidelines for the latest controller together with few buttons, a touchpad as well as sensors in tracking its orientation and where it would be pointing.

IBM Scientists Achieve Storage Memory Breakthrough

IBM Research – Latest Memory Technology – Phase-Change-Memory –PCM

Scientist at IBM Research, have for the first time demonstrated reliably storing 3 bits of data for each cell utilising a latest memory technology called phase-change memory – PCM. The existing memory landscape tends toextentfrom respected DRAM to hard disk drives to universal flash. However in the last several years PCM has attracted the attention of the industry as a probable universal memory technology based on its mixture of read/write speed, non-volatility, density and endurance.

For instance PCM does not lose data when it tends to power off unlike DRAM. The technology could endure at least 10 million write cycles in contrast to an average flash USB stick that tends to top out at 3,000 write cycles. The break-through of the research has provided quick and easy storage in catching the exponential growth of data from the mobile devices as well as the Internet of Things.

IBM scientists tend to envisage standalone PCM together with hybrid application that would unite PCM and flash storage together with PCM as an exceedingly fast cache. For instance the operating system of a mobile phone could be stored in PCM permitting the phone to launch within a few seconds. In the initiative space, the complete database can be stockpiled in PCM for fast query processing for time-critical online application like financial transaction.

Two Stable States – Amorphous/Crystalline

Machine learning processes utilising huge datasets would see a rapid boost on reducing the latency overhead while reading the data between iterations. The PCM materials tend to display two stable states, namely the amorphous – without a clearly defined structure and crystalline – with structure phases, of high and low electrical conductivity, respectively. Scientists at IBM and the other institutes had successfully demonstrated the potential to store 1 bit per cell in PCM earlier. However, presently at IEEE International Memory Workshop in Paris, for the first time, the IBM scientists are presenting, successfully stored 3 bits per cell in a 64k-cell array at higher temperatures and after a million endurance cycles.

 Dr Haris Pozidis, author of the paper and the manager of non-volatile memory research at IBM Research – Zurich had informed that `phase change memory was the first instantiation of the universal memory with properties of DRAM and flash, thus answering one of the grand challenges of the industry.

Novel Coding/Detecting Scheme Employed

He further added that reaching three bits per cell seems to be a significant milestone since at this density, the cost of PCM tends to be significantly less than DRAM and nearer to flash. In order to attain multi-bit storage, IBM scientists had developed a couple of innovative enabling technologies, a set of drift-immune cell-state metrics and drift-tolerant coding with detection schemes.

The new cell-state measure a physical property of the PCM cell more precisely, which tends to remain stable over a period of time and are hence insensitive to drift, affecting the stability of the electrical conductivity of cell with time. In order to provide extra strength of the data stored in a cell over ambient temperature fluctuation, a novel coding as well as detecting scheme had been employed.

The scheme tends to adaptively change the level threshold which is used in detecting the stored data of cell so that they follow variation owing to temperature changes. The outcome is that the cell state can be read reliably over long period of time after the memory is programmed and hence offers non-volatility.
