3D LED Printer Makes a Contact Lens Display Possible

3D Printed Contact Lenses 

According to researchers, 3D printed contact lenses can now be used like Google Glass or head up display showing the wearers’ data as well as monitor their health. 3D printer build up metallic or polymer material to form objects when instructed by computer code that conveys to the machine the desired dimension together with the appearance of the product, though this machine is more complex.

Researchers have started constructing prototypes for contact lens displays, and their biggest impediment was parts of fabrication which on a theoretical level is not difficult to build display in a contact lens but building and placing the tiny interrelated parts on a tiny polymer disk is a difficult task.

The 3D LED printer is a 3D quantum dot LED printer which on breaking the concept of an LED to its most basic form, researchers envisaged that they need not think of LEDs like small plastic light bulbs but stacks of interacting substance.

The printer on its part could lay down an LED with a sandwich type of a structure which is not unlike a single pixel in a display of OLED and get emissive layer which is nanoparticles of cadmium selenide that is referred to as quantum dots.

Active Approach

The quantum dots or nano sized crystals of certain substance exhibit unique or particular useful electronic properties. These are sandwiched between one layer which can donate electrons and one layer that accepts them and the entire process can be fused to a surface due to the bottom adhesive layer that is activated with the help of UV light.

Moreover, the printed LEDs are ultra-thin, almost transparent as well as flexible. The transfer of electrons through quantum dot layer causes the dots to produce photons of light and the main advantage of it is that they can be made to emit light at very specific wavelength or colours.

It means that the quantum dot screens can display more recreations of colour accurately but it would not be the first priority for contact lens display which will get static, sensible image in the user’s eye.The pixel on the other hand in a contact lens display could take one of two forms and the active approach uses individual pixel as a light source and emits photons in the eye, creating an image directly.

Passive Approach 

The passive approach on the other hand uses less power though it would be more difficult using individual pixel to bend the incoming light from the environment to portray a new picture on the retina. The issue with active approach is that it needs a good amount of power to go on and wireless power collection relies partially on physical size of the collecting antenna.

When the antenna must be physically fitted in a contact lens, it creates a hard upper limit on power supply. It is unlikely to start printing smartphone screens pixel by pixel since manufacturing in bulk would be quicker and cheaper and while doing so, things like putting LEDs in circular area of contact lens less than 2 mm, it could be helpful. The cost of the prototype print cost about $20,000 to create though there is a possibility in reduction of cost in the near future.

Frontal Car Crash Test gives Several Top Manufacturers poor rating, while Toyota Receives Good

The frontal crash test by Insurance Institute for Highway Safety (IIHS) has become a serious benchmark for ensuring traveller’s safety since it made the first appearance. Nowadays car manufacturers from U.S. is checking the newly build car’s efficiency to reduce the damage when it faces frontal crash with another vehicle or tree or poll. Recently IIHS performed a frontal overlap car test with four majorly sold minivans in U.S., which are The Chrysler Group LLC Dodge Grand Caravan, Toyota Motor Corp Sienna, Nissan Motor Co Quest and The Chrysler Town & Country.

Minivans are hugely popular in U.S. villages and small town because of its capability to carry small to large carriages and also almost all delivery agencies use this type of minivan for transportation in U.S. towns. Crash test is being done to check how the car defence prohibits the hit to make severe damage. According to the test report, except Toyota Motor Corp Sienna, rest of the candidate minivans performed very poorly in the test. Toyota’s minivan joins Honda Motor Co Odyssey, which received ‘best safe pick-up’ rating from IIHS earlier.

How the test is being performed?

This test by IIHS only replicates the actual event of what happens during a road accident involving the frontal part of the car. In this test, around 25% of the front of a car hits an obstacle at an average speed of 40 miles per hour. The camera and sensors installed at different parts of the car, evaluates the car’s response to the hit.

Detailed report:

Minivans are popular mainly within parents and family-minded customers because of its road safety feature. According to the test report, three of four candidate models, namely The Chrysler Group LLC Dodge Grand Caravan, Nissan Motor Co Quest and The Chrysler Town & Country, when hit with an overlap obstacle, showed severe damage to the car and allowed high degree of intrusion involving the driver’s area.

A spokesperson from the institute stated that the Nissan minivan structure just collapsed like ‘a house of cards’. The Chrysler automobile minivans also showed severe damage as the steering wheel moved out of the coordinated place. This results in making the airbag less efficient and simultaneously driver’s head hits the dashboard. IIHS test report given The Chrysler Group LLC Dodge Grand Caravan,Nissan Motor Co Quest and The Chrysler Town & Country very poor rating, while Toyota Motor Corp Sienna received an acceptable rating prescribing the car safety to be ‘Okay’.

Toyota Sienna was also ranked in ‘Top Safety Pick up+’ car list, as it warns the driver prior to any possible front collision and also features an automatic brake system.

Response from the manufacturer:

After the release of test report, concerned manufacturers released mixed responses. Nissan released an official statement which says the company will continue the revision of the models and will improve the safety. While Chrysler automobile group stated that this single test cannot state their car to be damage prone.

BMW Decides To Manufacture the Takata Airbag Inflators in Germany

The Germany based BMW has announced its plans to help the Japanese counterpart company in delivering the replacement inflators quicker by assisting them in moving their production facilities from Mexico to Germany. BMW has explained that their decisions are in wake of the serious issues regarding the quality of the manufacturing at the Mexico plant raised by the U.S. safety regulators.

What Made BMW Take such Dramatic Steps? 

Automobile manufacturer who actively uses the Takata inflators also includes the Toyota Motor Corp. The Takata inflators seem to have the potential of blowing up with excessive force and spraying occupant with deadly sharp metals. It should also be noted that it isn’t feasible to switch to other suppliers in order to meet the demands for the replacement parts at this juncture.

Therefore the U.S. safety regulators are lending a helping hand by supporting BMW efforts in shifting the inflator production plant from Mexico to Takata plant in Freiberg, Germany. The Takata inflators are being currently investigated in at least five death cases in U.S.

German Facility Promises To Boost Production Capacity

Japanese company has the ability to produce 200 inflators per hour on its single production and at the moment it just has two of them in active use. This concludes that that it would be able only 1 million replacements in next five months at this snail pace. But the demand stands at 32 million for replacements parts. Therefore this shifting of production facility is taking place in order give a genuine boost to the production capacity of Takata.

Takata Runs into Serious Trouble

U.S. regulators have asked several questions relating to the Mexian plant production quality defects. The officials from Takata, Chrysler Group, Honda Motor Co and NHTSA would be testifying to a U.S. Senate panel in this regard on Thursday. Furthermore NHTSA has also ordered Takat and five other automobile manufactures to expand the U.S. recall of vehicles with the defective air bags.

Automobile Manufacturers Look For Alternatives

Companies like BMW, Toyota and Ford Motor Co are looking for quick solution to the problem of getting replacement parts. They are planning to buy replacement parts from the rival supplier but even such option is unviable as it would more than a year to get an alternate inflator production line in place.

Some of the automakers are looking to use completely new parts from other suppliers but they soon found that doing such a thing would require bringing in extensive changes in their cars. Companies like Honda, Toyota and Ford had considered this option. However problem would not cease to exist by implementing this as the suppliers would still fall short of keeping up with the demand. Even the companies go ahead with this proposition and build cars as per the exact specifications of the new inflators still it will take around a year to get it in the market.

Therefore the companies like Nissan, Mazda Motor and General Motors have dropped this idea and hope that Takata would be able to solve its supply problems in due time.

Will Apple's Next iPhone Capture DSLR Quality With 2 Lenses?

iPhone is one of the most loved brand and trusted among the people around the world and this could be the reason why rumors always keeping along with the brand. Although Apple has just released their latest version, iPhone 6, there are already market rumors that the company is working on the next version of the phone having two lenses on the camera, which will produce images with DSLR-quality.

How it all started? 

This rumor was sparked after a post on podcast entered by Daring Fireball’s John Gruber. John is highly respected Apple-focused commentator and well connected in their ecosystem. He is known to have never made any unwarranted predictions. In the month of August, John posted an update indicating that Apple is working on their wearable device thing and it is expected to be released in September. However, as people started getting curious about the same, he later stated that the post was just a joke and was meant to poke fun of the Motorola's smart watch, which resembled a flat tire. Whether rumor or joke; the company indeed unveiled their wearable smart watch in the month of September.

No damage done due to rumors

These rumors have not done any serious damage to the company and been told in a simple statement to the public. It all started with the statement indicating the news of the company working on upgrading the phone’s camera to two lenses. The lenses will be able to capture SLR quality images. As per to John, the new camera will not be able to replicate the SLR quality at technical level, but this sure is a huge step from the company’s end.

So what is special? 

John backed away from any kind of comparison being made between iPhone and SLR or DSLR on technical basis. The main point of this post was to highlight the current iPhone users will be able to migrate to the new high-end camera. Apple’s iPhone is known to capture the best of the images and one of the best camera due to which many people have stopped using the stand-alone camera. If the rumors have to be true, then this giant leap in terms of capturing moving images without any blur and ability to zoom will be enough to encourage many iPhone users to upgrade their iPhone 6 to the newest version.

If Apple is considering this option then, they will not be the first one to try this option out. HTC has already used the dual-camera system in their HTC One M8. HTC phone allows the users to change their focus angle even after snap has been taken.

If Apple is working on taking this new leap in terms of improving the quality of their camera by using CMOS imaging sensor system of Sony, then this move will be wholeheartedly welcomed by their customers. Although it is unlikely that the company has get the DSLR quality in their iPhone, but any change will be enough to spark the excitement in the customers towards upgrade.

China Suspected Of Attacking USPS and NOAA

Last week, National Oceanic and Atmospheric Administration and the United States Postal service had confirmed that that there were attacks on their computer system. These cyber attacks went on for a month and suspected to be originated in China. According to USPS, these attacks compromised the private information of nearly 800,000 employees. The type of information that was at risk includes date of birth, names, addresses, date of employments and Social Security numbers. This information’s is very important as anyone can forge and influence the service as well as other government agencies.

What is at risk? 

According to CTO, Greg Kazmierczak, Wave systems, specific details about any individual can be risky as the attackers can use them to spear phishing attacks later on. According to Eric Chiu, the president and founder of HyTrust, apart from attacking the companies, this personal data can be harmful to the employees against themselves. He stated that compared to the customer’s date, employee data is more valuable as the companies have a record of their social security, finance and home. This can help the attackers to forge the identity.

NOAA Breach: 

Even though USPS had not pointed fingers at anyone pertaining to this attack, but China is being suspected behind these attacks. According to CEO of ThreatTrack, Julian Waits Sr., this revelation could not have come at any bad time, now the customers will get concerned about their identity and their personal security. NOAA was called on the carpet regarding the breach originated from the Chinese systems. They informed Frank R. Wolf from the Virginia Republican that they sure that their systems were hacked by China. However, they were unable to confirm that this attack specifically originated in China.

The Breach Diary: 

1. 10th Nov- USPS confirms the cyber intrusion and gave an estimation of 2.9 million affected customers.

2. 10th Nov- Sarah Hendrickson appointed as the chief of security.

 3. 11th Nov- Microsoft fixed a 19-year-old bug, which can be used by the hackers to launch drive-by attacks.

4. 12th Nov- 24,105 stories about data breach was reported by the Deloitte

According to another news report, after hacking into USPS, days after this event, hackers broke into U.S. National Weather Service computers. This attack was confirmed by the US National Oceanic and Atmospheric Administration. This attack took place just two days after the attack on the USPS. According to the American media reports, many of the NOAA services were put under temporary maintenance or were taken down temporarily. One of the representatives of the company told the Washington post that they know it was an attack from the hackers and it originated from China.

The agency had failed to inform appropriate authorities regarding these attacks. Although there is enough evidence pertaining to these attacks, NOAA refused to comment on the issue pertaining to the Chinese attacks on the United States Satellite network and weather conditions. They haven’t confirmed if this attack affected their notification or impacted any classified data.
