Apple Ipad Air 2 and Ipad mini 3

Recently Apple has introduced its  new iPads including the updated iPad Mini 3 and its thinnest tablet ever, the iPad Air 2.
Both the products look identical to the previous ones but they are more advance , deligated and faster than the previous versions. Apple says this chip is 40 per cent faster than previous processor and has 180 times the graphic performance of the original iPad.   But ipad mini 3 is come with the A7 screen as the previous generation. One more thing is that ipad Air 2 is just half that original ipad.

SPECIFICATIONS:

DISPLAY AND WEIGHT

 Apple has kept the screen size at 9.7-inches for the iPad Air 2 with a 2048×1536 resolution at 264 pixels per inch (ppi). Apple has, however, introduced an anti-reflective coating on the tablet (the same as the iPhone) to reduce reflections on the tablet by 56 percent. If users were hoping that the iPad Air 2 would have a sharper screen, that hasn’t changed. iPad mini 3’s screen is also at 7.9-inches with a 2048×1536 resolution at 326 pixels per inch (ppi).
It should be noted though that the iPad Air 2 is thinner than the iPad Air. The iPad Air 2 is 6.1 mm (0.24 inches) thick while the iPad Air was 7.5 mm (0.29 inches) thick. The iPad Air 2

PROCESSORS AND MEMORY CHIP

The iPad Air 2 comes with the A8 64-bit architecture processor along with the M8 motion co-processor. whereas  the ipad mini 3 comes with the A7 processor with M7 motion co-processor which isn’t an improvement at all from the earlier version.According to Apple, the A8 chip on the iPad Air 2 delivers a 40 percent improvement in CPU performance and 2.5 times the graphics performance of the iPad Air
These ipads are come with the  16, 64 and 128 GB versions only.

BATTERY LIFE AND OS
Comes with the 10-hour battery life. iPad Air 2 also includes an all-new barometer which senses air pressure to provide relative elevation. This is not included in the iPad mini 3.
These are come with the latest ios 8.1

IMPROVED CAMERA

Camera: Apple has finally improved the camera on the iPad Air by introducing an 8 megapixel rear (or as Apple calls it iSight) camera although it has kept front camera at 1.2 megapixels which is disappointing. As far as camera improvements on the iPad Air 2 go users can now take panoramic shots, shoot time-lapse video, slo-mo video and 1080p HD video.

According to Apple, the FaceTime HD camera now captures over 80 percent more light than iPad Air’s camera, and features burst mode as well as HDR stills and video.

Sadly, the iPad mini 3 camera hasn’t changed much and remains the same as the iPad mini 2.

PRICE AND COLOURS

 The iPad Air 2 Wi-Fi only versions will be priced as follows: 16GB will start at Rs 35,900, 64GB for Rs 42,900 and 128G for Rs 49,900. The iPad Air 2 WiFi plus cellular will be priced like this: 16 GB for Rs45,900, 64GB for Rs52,900 and 128GB for Rs59,900.

The iPad Mini 3 with Wi-fi will start at Rs 28,900 (16GB), Rs 35,900 (64GB) and Rs 42,900 (128GB). The iPad Mini 3 Wi-fi + Cellular models will be sold at Rs 38,900 (16GB), Rs 45,900 (64GB) and Rs 52,900 (128GB).

iPad Air 2 and iPad mini 3 is coming in GOLD colour as well along with Space Grey and  silver also.

TOUCH ID AND APPLE PAY
This the biggest plus to the iPad Air 2 and the iPad mini 3 as both come with the Touch ID fingerprint scanner which we’ve seen on the iPhone 5s, iPhone 6 and iPhone 6 Plus.
Touch ID gives iPad Air 2 and iPad mini 3 users a simple and secure way to unlock iPad with just the touch of a finger, plus the ability to authenticate within apps to better protect logins and data.
VERDICT
Apple has not made many changes in ipad Air 2 than their previous version(i pad Air)
But we can see some improvements in IPad mini 3 than its Previous versions of ipad mini.
If you want something new you can buy ipad mini 3 according to your budget.

Flying car that can be rule

 The world of modern vehicles to expect a revolution. Ordinary cars are replaced by hybrids and electric cars, and even try to up in the air.

The concept of flying machines – like those worn in the sky in the movie “Back to the Future 2″ – develop for decades. However, until now there is not really an impressive specimen, ready for everyday use.
 It is believed that even modern technology does not allow you to make cheap enough (for the average driver), the vehicle of its kind.
However, the company AeroMobil from Slovakia seems to be planning to challenge that assertion. Once this the futuristic project is being developed in Slovakia. We are talking about a car that turns into a small plane and rises.
Judging by the brochures, then AeroMobil looks impressive. It has an unusual design. Indeed greetings from tomorrow. Hybrid sports car and airplane.

Design weighs only 450 kg, the wings are easy to fold, so there is no problem with parking. In this respect the invention is not inferior to passenger “brethren.” Power reserve in the ground mode – 875 km. With regard radius of flight,are modest – 700 km. In air power Rotax engine 912 is sufficient for acceleration to 200 km / h. And on the way AeroMobil racing at 160 km / h. No problems with the fuel not. For powerplant fit regular gasoline from a nearby gas station. How many people are allowed to take “on board”? Two. Driver and one passenger.
While not too clear, how all of this is true. We can only hope, that on presentation AeroMobil will be able to get off the ground and win the hearts of the audience.

Robotic exoskeleton

This invention can be proved very useful for those people who are effected by stroke or debilitating injury. peaople uses method of physical therapy to overcome from that type of situations but that are not proved useful to them. But now they can change their lives with the new robotic exoskeleton made by a team of mechanical engineering students at University of Pennsylvania named as

 Titan Arm:  This is an efficient, lightweight, and surprisingly powerful robotic limb. 

Its actuator, or electronic muscle, could provide resistance during therapeutic exercises and can augment strength, allowing its wearer to lift an additional 40 pounds with little effort.

This will be very affordable exoskeleton which will be cost you very less.

To ensure a slimmer frame than other exoskeletons and make Titan Arm easier for patients to use, the team situated its actuator in a backpack instead of in the limb itself. They also milled load-bearing parts out of aluminum to limit weight and power consumption. McGill, the electronics lead, created a software-and-sensor package to track arm movements and wirelessly relay the data. This would allow a patient to use a Titan Arm at home and a therapist to remotely monitor the exercises.

The price is not revealed yet.  Potential beneficiaries, including stroke victims and an injured snowboarder, have already reached out to the team with encouraging comments.  This product developing  cost is only $2000 . They are now designing a more refined version. “We’ve been looking at 3-D printing to fully customize components, like tailoring a suit,” says Parrotta.

Main features are: 

1) Battery:

Lithium-polymer battery that can be worked for whole day.

2) MUSCLE:

An electric motor in the backpack winds steel cables to rotate pulleys and induce arm movement. Beattie (left) designed a support system to safely distribute weight across a hip belt, elbow straps, and back plate.

3)Development cost:

$2000 .

Conclusion:

This technique can change the lives of many people and can be worked as a hope for the physically challenged people. This technology  in its  developing stage but it can be proved very suceeful in near future and many people get benifit from it.
