How many megapixels does the human eye have???
you see things one way, and your camera sees things differently.
So, what is the resolution of the human eye, at which a camera would be able to truly capture an image the way the eye sees it?
The answer is 576MP, the technical breakdown is as follows:
Consider a view in front of you that is 90 degrees by 90 degrees, like
looking through an open window at a scene. The number of pixels would be
90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 =
324,000,000 pixels (324 megapixels).
At any one moment, you
actually do not perceive that many pixels, but your eye moves around the
scene to see all the detail you want. But the human eye really sees a
larger field of view, close to 180 degrees. Let’s be conservative and
use 120 degrees for the field of view.
Then we would see 120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.
The full angle of human vision would require even more megapixels. This
kind of image detail requires A large format camera to record.
Therefore, once our cameras reach 576MP, the pictures you take with your camera will look exactly the same as you see them.
Just be patient, its coming out, soon.. In the next millennium.. Maybe.
Wireless charging is any of several methods of charging batteries
without the use of cables or device- specific AC adaptors. Wireless
charging can be used for a wide variety of devices including cell
phones, laptop computers and MP3 players as well as larger objects, such
as robots and electric cars. There are three methods of wireless
charging:
>inductive charging
>radio charging and
>resonance charging.
Inductive charging is used for charging mid-sized items such as cell
phones, MP3 players and PDAs. In inductive charging, an adapter equipped
with contact points is attached to the device's back plate. When the
device requires a charge, it is placed on a conductive charging pad,
which is plugged into a socket.
Radio charging is used for charging items with small
batteries and low power requirements, such as
watches, hearing aids, medical implants, cell phones, MP3 players and
wireless keyboard and mice. Radio waves are already in use to transmit
and receive cellular telephone, television, radio and Wi-Fi signals.
Wireless radio charging works similarly. A transmitter,
plugged into
a socket, generates radio waves. When the receiver attached to the
device is set to the same frequency as the transmitter, it will charge
the device's battery.
Resonance charging is used for items that
require large amounts of power, such as an electric car, robot, vacuum
cleaner or laptop computer. In resonance charging, a copper coil
attached to a power source is the sending unit. Another coil, attached
to the device to be charged, is the receiver. Both coils are tuned to
the same electromagnetic frequency, which makes it possible for energy
to be transferred from one to the other.The method works over short
distances (3-5 meters).
The idea of wireless power transmission
is not new. In 1899, Nikola Tesla wirelessly transmitted 100 million
volts of electricity 26 miles to light 200 bulbs and run an electric
motor. However, at that time direct current ( DC, which is the wired
method) and alternating current (AC) were competing technologies. DC,
backed strenuously by Thomas Edison, emerged the winner.

Cyber Forensics Investigation Procedure
PAN
is a 10 digit alpha numeric number, where the first 5 characters are
letters, the next 4 numbers and the last one a letter again. These 10
characters can be divided in five parts as can be seen below. The
meaning of each number has been explained further.
1. First three characters are alphabetic series running from AAA to ZZZ
2. Fourth character of PAN represents the status of the PAN holder.
• C — Company
• P — Person
• H — HUF(Hindu Undivided Family)
• F — Firm
• A — Association of Persons (AOP)
• T — AOP (Trust)
• B — Body of Individuals (BOI)
• L — Local Authority
• J — Artificial Juridical Person
• G — Government
3. Fifth character represents first character of the PAN holder’s last name/surname.
4. Next four characters are sequential number running from 0001 to 9999.
5. Last character in the PAN is an alphabetic check digit.
Nowadays, the DOI (Date of Issue) of PAN card is mentioned at the right
(vertical) hand side of the photo on the PAN card. .........!
