Lumus Lens, a new age wearable lens Technology
Lumus is the name for the new age lens technology. You may not
know the name Lumus now, but expect to be hearing a lot from them
in the future. When we first met the Lumus rep Ari Grobman two
years ago he showed us some amazing technology. It was basically an
augmented reality display embedded into a standard lens that could
fit into a standard pair of glasses. The 720p model displayed a
binocular image at near HD quality right in front of your face,
allowing you to watch movies, play games, and even interact with
mobile devices on a screen floating in mid-air.
Now the team is showing off the next incarnation of Lumus,
adding a full Android computer and camera to create a system that
puts Google Glass to shame. The system can handle gestures you
swipe away notifications and even display map data on the ground in
front of you. I tried it and it worked perfectly. Imagine a small
screen or screens floating in front of your eyes that you can
completely control with your gestures.
Best features of Lumus Lens wearable technology
1. Unobtrusive, natural look and feel of regular eyeglasses,
which can be worn all day, even when screen is off
2. Huge expandable screen with image appearing even larger over
distance
3. Situational awareness enabling watching on the go while
seeing what's going on around you
4. Hands-free flow of critical data, keeping you constantly
connected no matter what you are doing
5. Personal and private screen allowing discreet viewing of
video and data anywhere
6. Augmented reality content overlaid on what you see, enabling
revolutionary applications
7. Stereoscopic image enabling mind-blowing 3D video and
gaming
8. No fatigue or dizziness because of open peripheral vision and
proprietary alignment methods and procedures
While it may give Google Glass a run for its money the tech will
not arrive on the market anytime soon. At the moment the company is
working with some of the top manufacturers and it seems that each
of those companies is waiting to see what the other is going to do.
Meta, the wearables company is using a version of the tech in their
upcoming glasses. Grobman said that what he was most excited about
in the future was binocular devices. He went on to say Our
customers can do some cool stuff, Theyre just not ready yet.

Paper battery, an introduction
A paper battery is an energy storage device. It is used as a
battery and also as a good capacitor. It is formed by combining two
things which are carbon nano tube and the cellulose based paper.
The process to make paper batteries start with making a cathode and
anode from manganese dioxide and zinc. These are then printed onto
the cellulose paper. The nanotubes made from carbon are then added.
The electrolyte is an ion based liquid solution.
Working of Paper battery
Once the paper is immersed in the ion based liquid solution,
there is a chemical based reaction between the liquid and the
electrodes, in this case the nanotubes. The electrons which are
generated move from the cathode to the anode to generate
electricity. The best way to increase the output is to stack
different paper batteries, one over the other.
Use of paper battery
1. It has a paper thin sheet of cellulose and it is infused with
the carbon nanotubes. It is acting as a electrodes. And it also
acts as a good conductor storage device.
2. It provides long steady power by functions as a
superconductor and a lithium iron battery.
3. It can be twisted, folded , rolled or it can be cut into your
needed shapes without any loss in its efficiency in its output.
4. It is light weight due to the nanotubes and it is used in the
portable electronic devices and in automobile toys, such as remote
appliances also.
5. It also used for medical devices like pacemakers, because it
is non toxic and biodegradable well suited for medical
appliances.
Practical Uses
1. Can be used to power smart tags.
2. Can be used to power single use medical devices.
3. Can be used to make items like gaming cards interactive at
very low cost.

E paper technology
Electronic paper is a display technology which makes the
appearance of an ordinary ink on a plain paper. Regular backlit
flat panel display used in electronic display emits light. While an
electronic paper display reflects light like a normal paper thereby
making it more comfortable for reading, and providing the visible
surface a wider viewing angle. The contrast ratio usually present
in electronic paper is same as a newspaper. The recent technical
upgrades have made electronic paper look better. An ideal e paper
display can be seen and interpreted in direct sunlight without the
image to get faded.
These displays make the beginning of a new area for battery
power information applications such as cell phones, pagers, watches
and hand-held computers etc. Two companies are carrying our
pioneering works in the field of development of electronic ink and
both have developed ingenious methods to produce electronic ink.
One is E-ink, a company based at Cambridge, in U.S.A. The other
company is Xerox doing research work at the Xerox's Palo Alto
Research Centre. Both technologies being developed commercially for
electronically configurable paper like displays rely on microscopic
beads that change color in response to the charges on nearby
electrodes. Like traditional paper, E-paper must be lightweight,
flexible, glare free and low cost. Research found that in just few
years this technology could replace paper in many situations and
leading us ink a truly paperless world.
Electronic papers can hold and preserve static text and images
for an indefinite period without using electricity. Flexible
electronic papers use unique plastic substrates and plastic
electronics for creating the display backplane. Through constant
research manufacturers are trying to provide the full color ability
and make these electronic papers look more real.
Though electronic paper is still under development, we can find
many products available in the market today. For example, many
mobile phones presently use e paper displays. E-paper is also used
in manufacturing electronic readers such as Amazon's Kindle, an
electronic reading device. Electronic paper technologies have a
lower refresh rate ratios compared to other low power electronic
display technologies.
