Korean Drama: Kim Tae Hee

It's been quite long that I haven't write any actress from Korean Drama, last time was some time in 2009. But after last 4-days marathon watching My Princess, I decided to write this topic once again in this blog.

First time saw her in Stairway To Heaven acted as an Antagonist main character in 2003, then as main actress in Love Story in Harvard in 2004. This young Korean Actress, Kim Tae Hee, has been in a long journey in her career before landed at her highest level as main actress in IRIS (2009) and the latest, My Princess (2010).

What I can remember is her cute face, and beautiful-bright-and-big eyes in Stairway To Heaven (especially when she is angry or showing her evil character... he he he), then cheerful character in Love Story In Harvard, then serious character in IRIS. But still, her beautiful-bright-and-big eyes which eye-catching the most!

From tons of her pictures those can be found in internet (just google it!), here are some pictures of Kim Tae Hee that I like most:

FYI: Wireless Charging

Thinking of charging your mobile phone, smartphone, gadget, or gaming device without power cable? Is it possible? Seems like a future in the sci-fi movie... But, wait! It is something that already does exist! There is already technology for wireless charging.

Reading from some resources in the web, there are three method of wireless charging:
  1. Inductive Charging
    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. This method is used for charging mid-sized items such as cell phones, MP3 players and PDAs.
  2. Radio Charging
    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. This method 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.
  3. Resonance Charging
    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). This method is used for charging items that require large amounts of power, such as an electric car, robot, vacuum cleaner or laptop computer.
But, well... actually it is not all wireless... the sending unit still needs to be attached to the power source using power cable and plug... so, the wireless one is the receiving unit.

For consumer products, this wireless charging still very limited. But, years ahead this technology will be more and more in the market. Today, I spotted one website which sells this wireless charging device for smartphones... quite interesting... the product called PowerMat Wireless Charging System.
