Google_Glass
Latest Invention – Google Lens

The latest invention which has been developed by Wichita State University professor Jibo He and Barbara Chaparro who worked with graduate student Long Wang on the project known as Google Lens, have found ways to be more creative and innovative on inventing a device which could have positive development in the medical field in the future.

The device has been invented which can be attached to the Google Glass wearable computer and gives the user an enlarged image. The device seems to be an accessory lens; a wearable product which uses voice control to enable users to check information easily when their hands tend to be busy and the information is displayed in Google Glass see through head mounted display with its built-in camera enabling video sharing as well as remote conference.

The Google Glass responds to voice commands and has a tiny screen with a camera which is placed to a glass-like frame but the display seems to have one setback wherein its webcam has a narrow field of vision of 54.8 degrees horizontally by 43.5 vertically with limitation to its use in some applications. The attachment of Google lens enables the user to capture an enlarge vision of 109.8 degrees horizontally and 57.8 vertically.

The Importance of Expanding Google Glass view

Several professionals have the need to use Google Glass for many things like surgery and medical training to usability research as well as flying an aircraft. Most of the hospitals which include Wesley Medical Centre in Wichita and the Brigham & Women’s Hospital in Boston are developing Google Glass applications in order to enhance their medical services, new doctor training and surgery.

It is said that `the object needed to broadcast may be out of the field of view of Google glass and despite all of its remarkable features, Google Glass has some limitations in its hardware and Google lens solves the problem’. The device includes a holder which is attached to the lens of the frame of Google Glass where the lens that is fixed into the accessory has the capabilities of being changed with ease. Moreover, the accessory lens is helpful in the bottleneck of Google Glass camera improving and expanding Google Glass’ application in professional areas.

Patent Files for Google Lens – Awaiting Approval

Both Jibo along with Chaparro has applied for a U.S. patent for Google Lens and are waiting for its approval. They are both part of Wichita State University psychology department where Chaparro is the director of WS’s Software Usability Research Laboratory studying human-computer interaction and working with industry on software design and usability.

Jibo He on the other hand was among the first Google glass Explorers in 2013 and through the Explorer program, was granted by Google, programmers and researchers early access to the Google Glass device prior to going on sale to the general public and though it is not available to the general public, some businesses like hospitals having been using Google Glass.

Initial research related to whether it would be safe to drive while interacting with Google Glass and later on studied how Glass could be used in detecting when the driver was fatigued.

Google's Vint Cerf Warns of 'digital Dark Age'


Vint_Cerf
In recent interview with Pallab Ghosh, Google's Vint Cerf warns about 'digital Dark Age'. Vint Cerf, who is a Vice-president of Google, says that he is worry about all the images and documents, which we have saved on our computers or on other devices because in future we can eventually lost them. He believes that it could occur as software and hardware become obsolete.

Vint Cerf fears that in future our generations will have very little or no record about 21st Century, if we will face digital Dark Age scenario. He made his comment at science conference in San Jose, where he arrived in a three-piece suit, for annual meeting of American Association for the Advancement of Science. We all know that he is an iconic figure, who love to define that how data packets moves in all over internet and he is the only Google employee who love to wear tie and suit.

Now his main focus is to solve this new problem of digital Dark Age, which is threatens to eradicate our past or history. Our memories, our life, our happiness, our sorrows and cherished family photographs now exist as bits of information on our hard drives or in cloud. But change is the law of nature and so technology moves on and we can lose them while accelerating the digital revolution.

What is Digital Dark Age? 

In report, Pallab Ghosh from BBC told that “I worry as Mr. Cerf told me that in near future you and I can experience the things like this because old formats of documents, which we have created in present they may not be readable in future when latest versions will come in existence and we all know that software’s backwards compatibility is not guaranteed.

And due to that in the presence of archives of digital content, we will not be able to scratch or use it as we may not know what it is. While promoting the idea to preserve each and every piece of software, technology and hardware he said that with the help of this idea we will be able to overcome from this issue and we can store them in the form of digital or in servers over could as things happens in a museum. If this idea of Mr. Cerf, will work, so our memories could be accessible for upcoming generations.

The recommended solution is to take an X-ray snapshot of the operating system, application, and content together with the detailed description of the machine, which runs on and able to preserve that for long periods such as; 100 to 200 years.

And these digital snapshots will be helpful to recreate the past in the future. There will be companies in future who will provide these services and therefore I suggested to Mr Cerf that how companies will exist for hundreds of years and because of that we cannot guarantee that both personal and human history would be safeguarded in the long run.

But Vint Cerf replied that we are trying to capture X-ray snapshot and they will be transportable from one place to another and so it will be easy to move them from Google cloud to some other cloud or move it into a machine.

Lab on a Chip Turns Smart Phones Into Mobile Disease Clinics


Lab_on_Chip
A Device – Easy to Use Smartphone – Test Multiple Diseases

Early detection of any infectious disease is a very important public health issue and the development from web and mobile based communication together with novel bio-molecular detections abilities have come up with regards to public health infrastructure.

Progress in communications, computation and materials had given rise to new technologies like mobile phones and microfluidic chips. A cheap device has been created by researchers from U.S. and Rwandan, who have been making progress in designing cheap, easy to use smartphone attachments which could test patients for multiple dangerous infectious diseases within fifteen minutes. In the present world, smart phone have been paying up bills, tracking diets as well as recording our sleep and soon they will be utilised in the global fight against the various diseases with researcher making headway in this field.

A drop of blood is all that is needed from a finger prick of the person and on pressing the device’s big black button would create a vacuum that can suck the blood into a maze of tiny channels in its disposable cartridge which is the size of a credit card.

Functions – Lab Based Blood Test

Several detection areas trace any antibodies in the blood which could reveal the presence of a certain disease. It needs a little bit of power of the smartphone which helps in detecting and displaying the results of a disease. The team states that an iPod Touch has the potential of screening 41 patients on a single charge. A field test was conducted by the researchers of the device at three Community clinics at Rwandan where the health care workers screened ninety six patients for HIV and active and latent forms of syphilis.

A Lab on a chip could turn smart phones into mobile disease clinics and HIV and syphilis can now be detected in minutes with the use of cheap lab on chip device. The dongle being small and light, can be easily connected to a smartphone or a computer for the required power and the device provides the test results on the phone screen in fifteen minutes, instead of the two or more hours with the prevailing method.It is similar to all the functions of a lab based blood test and works by detecting antibody markers of any infectious diseases.

High Sensitivity & Ease of Use – Powerful Tool

On comparing with the gold standard laboratory tests, the team’s online report in Science Translational Medicine stated that the dongle was ninety six percent accurate in detecting infections, missing one case of latent syphilis. Inspite of a 14% false alarm rate, the researcher state that the device’s high sensitivity and ease of use makes it a powerful tool for diagnosing deadly diseases especially in the case of pregnant women.

They are now making progress in preparing a large scale trial for the $34 device which probably would enable mobile clinics and health workers with reliable and quick disease screening especially in the remote locations of the globe. Detecting a disease in time helps in timely diagnosis and treatment which could be helpful in early recovery from the ailment. Timely detection of the infection of those that are not common or have not been diagnosed in certain areas could be more vital.

New Algorithms Locate Where a Video Was Filmed From Its Images and Sounds


geo taggging
Creation of A System to Geolocate Video

A system capable of geo-locating video on comparing with their audio visual content with worldwide multimedia database has been created by researchers from Ramon Llull University in Spain for instances when textual metadata is not relevant or available. This could be helpful in the future, in locating people who could have gone missing after posting images on social networks or to recognize areas of terrorist activities. Several of the available online videos have text providing information on the destination it was filmed though there are others which do not provide the information which complicates the application of the frequent geo-location tools of multimedia content.

To resolve this issue, scientists from the La Salle campus at Ramon Llull University – Barcelona - Spain, have come up with a system which helps in locating the videos without any indication of the location where they were produced on the map, which is very challenging, taking into account the major part of the scenes of daily life minus the appearance of clearly recognizable places. Since they are not accompanied with text, the system is based on the recognition of the images or frames and the audio.

Physics & Mathematical Vectors Taken

One of the authors, Xavier Sevillano, states that `the acoustic information can be as valid as the visual and on occasion even more when it comes to geo-locating a video. In this field the use of some physics and mathematical vectors is taken from the field of recognition of acoustic sources because they have already demonstrated positive results’. Data gathered is put together and diverted into clusters, to enable using computer algorithms that has been developed by researchers and compared with a large collection of recorded video that have already been geo-located across the world. The team in their study published in the journal - `Information Sciences’, used around 10,000 sequences as reference from the MediaEval Placing task audio-visual database which is a benchmarking initiative or assessment of algorithms for the purpose of multimedia content. Sevillano states that `the videos that are similar in audio-visual terms to what they need to find, are searched for in the database, to identify the most probable geographical coordinates’.

Recognized the Need for Greater Audio-Visual Base

The researchers also indicate that the proposed system inspite of a limited database with regards to size and geographical coverage has the potential of geo-locating video accurately than its competitors. Moreover, it is also capable of locating 3% of videos within a radius of ten kilometres of its actual geographical location and in 1% of the cases; it tends to be accurate to one kilometre.

The researchers have also recognized that their system may need a greater audio-visual base in order to apply it to millions of videos that tend to circulate across the internet though they highlight the usefulness in locating those which do not have textual metadata as well as the capable possibilities it offers. Sevillano further states that `this system could help rescue teams in tracking down where a person or a group may disappear in a remote area and detect the locations portrayed in the video that could have been uploaded in a social network before they lost contact.

Glassed-in DNA Makes the Ultimate Time Capsule


DNA
If you want to preserve messages for long terms such as; 100 years to 1000 years or more, so may be Blu-ray discs or USB sticks are good enough as now you have one more option to preserve even more data and that option is DNA time capsule. Theoretically, 1 gram of DNA is capable to hold 455 exabytes, which is enough to store all data held by Facebook, Google and other major tech company. DNA time capsule have incredible feature for durability as some of the DNA has been extracted and sequenced from the bones of 700,000-year-old horse, but this theory comes with certain terms and conditions.

In Zurich, Robert Grass from Swiss Federal Institute of Technology, said that “We all know that if we store it lying around, so we will lose the information” and because of that he and his team is working on ways to increase DNA's longevity with a single aim to store data for hundreds or millions of years. The process is simple to store the data on DNA is to encode the information on DNA stand whereas; the most simplest method is to treat DNA bases G and T as a 1 and A and C as 0. Of course if there will be any damage on DNA levels or in DNA holes, so there is method to recover that which is widely known as Reed-Solomon code or an error-correcting technique. Robert Grass and his team is also trying to mimic the way fossils for the purpose to keep a DNA sequence intact by excluding all water from environment, which is key to encapsulate the DNA in any microscopic spheres.


To test the longevity of storage system they encoded two venerable documents of 83 kilobytes, a 10th-century version of ancient Greek texts, The Archimedes Palimpsest and and The Swiss federal charter from 1291. And then DNA versions of these texts were kept at 60 °C to 70 °C for a week to simulate ageing and they found that documents are still readable without any major or minor errors. And result suggested that data in DNA form could last in 2000 or 2200 years if it will be at a temperature of 10 °C or little more.

Grass is trying to store all the current knowledge for future generations, but this method is so much expensive to generate DNA stand in present. In normal conditions the cost to encode 83 kilobytes is approx. £1000, so if anyone will attempt to do same with Wikipedia then it will run to billions. Apart from this Grass suggests that we should focus on what our upcoming generation or future historians might want to read rather than storing all information. He says that if you will see that how we look at the Middle Ages, so it can influence them and due t that we should save these types of specific information’s. But still Grass is not sure about what to put in a time capsule.
