What is the science used to create the Wii?

What is the science used to create the Wii?
detailed answer plz
and can some1 tell me how to make something the best answer
and who made the wii?

dknol answers:

There's not a single person who made the Wii. Nintendo has an entire division of roughly 200 people devoted to designing the hardware, and this time (unlike other systems), they discussed it with the software developers in Nintendo and their subsidiaries as well (for example, the Nunchuk came about when Retro Studios explained why the Wiimote by itself simply wasn't enough for a shooter like Metroid Prime 3).

The Wii is pretty much filled with cutting edge technology, though most of what is inside it is devoted to making it smaller and much less energy-hungry than its competators. But what most people care about is how the Wii remote works.

The Wii Remote is a wireless controller that communicates directly to the console through a Bluetooth connection. This sin't anything all that special, as cellphone wireless headsets have been using this for years. Bluetooth was chosen primarily for its data throughput and low battery consumption.

The Wii Remote has two seperate motion detection technologies at work, which are used for two completely different purposes.

The first is a solid-state accelerometer inside the device. You can think of a solid-state accelerometer as a cubic weight suspended in the air by six springs (one on each side), with electronics that are capable of measuring how compressed each spring is. This allows the device to sense what direction is down when not moving, and measure the speed and direction of the movements of the hand holding it. As such, it is the method used to recognize gestures. There is another accelerometer inside the Wii Nunchuk controller as well.

The second system is the infrared system. This is comprised of an IR camera in the end of the Wii Remote and the Sensor Bar which plugs into the Wii and is placed above or below your TV. Calling the Sensor Bar is actually a misnomer, as it doesn't sense anything. The Sensor Bar is simply a piece of plastic with two clusters of infrared LEDs (one on each end), with a wire that plugs into the Wii purely for the electricity to power those LEDs. The IR camera in the Wii Remote, when aimed at the Sensor Bar, sees these two clusters of LEDs (and any other heat sources in that area, such as candles, Christmas lights, pets, etc.) as bright points. It sends this image of the (hopefully) two points of light from the Sensor Bar to the Wii, which uses the locations of the bright points to determine the location and twisting orientation of the on-screen cursor.

Charles asks…

If you have a pace maker. How do you avoid radio waves if you don't know where they are located?

They claim that anyone using a pacemaker should stay away from Amateur Radio transmitters. I know that they can use up to 1500 watts of power (legal limit). You could be driving past there house while they are running this type of equipment. So what can be done to protect yourself from this type of risk if you don't know where or who is transmitting this signal? Thanks for taking the time to answer this question!

dknol answers:

I have a flyer that I wanted to post for you and couldn't, but here's the meat of what you need:

The following guidelines are suggestions for safe use of radio equipment:
Power in Watts
Minimum Distance of device from Antenna
3 watts or less
6 inches (15 cm)

Cellular Telephone, Cordless Telephone, Cordless Microphone, home wireless electronics
>3 – 15
12 inches (30 cm)

Citizens Band, Long Range Cordless Telephone, Invisible Fences, Walkie-Talkies
>15 – 30
24 inches (60 cm)

Marine band radios, GPS survey equipment, some jobsite radios
>30 – 50
3 feet (1 meter)
>50 – 125
6 feet (2 meters)

Commercial and government dispatch, e.g. Taxis, emergency vehicles
>125 – 250
9 feet (3 meters)
>250 – 500
12 feet (4 meters)
>500 – 1000
20 feet (6 meters)
>1000 – 2000
30 feet (9 meters)

Commercial broadcasting towers, Ham Radio
No exposures >100V/meter
High power broadcast towers

If the antenna transmits in a very directional pattern, it may be necessary for the patient to be further away from the antenna at the strongest part of the pattern. There is no concern when operating the transmitter/receiver when the cabinet shielding and coaxial cables are properly connected.
Radio frequency wireless communication technology such as Bluetooth for TV's, radios, computers, and other electronic devices should use the recommendations above. Radio frequency waves are used to communicate with or control remote electronic devices. Maintain a minimum 6 inch (15cm) distance between the transmitter/receiver and the implanted device. If the transmitter/receiver is closer than 6 inches (15 cm), there is a potential for inappropriate pacing, inhibition, triggering, reversion or ICD shock.

Robert asks…

Can I add a line to my cell phone plan and use this line as my home telephone?

Adding another lne to my cell phone plan costs me $10/month, is there equipment I can use to convert this to a home telephone to use for fax etc? Can I port my existing home telephone to my new cell line that I want to use as my land line. Thanks

dknol answers:

Yes you can…

Many cell providers are starting to offer something similar to verizon's home phone connect

if your provider does not offer this, then you could always get a home phone that has bluetooth link technology, or a bluetooth gateway such as the xlink

Donna asks…

Can I get a bluetooth for my home office phone?

I have two offices and switch frequently between my cell phone and my home office phone. my current home office phone requires a cheap corded microphone / earbud. Is there a way to hook a bluetooth up to this?

dknol answers:

Or you can try the new “Link to Cell” Dect 6.0 wireless phones system from Panasonic, this allows you to link up to 2 cell phones (2 different number) and a land line together, then you can answer and make phone call from each line using a single headset (expandable) blue-tooth technology, plus you get good cellphone signal anywhere in your office or house as your cellphone can be left where it got strongest signal!!! Check it out at , I bought one set and I love it!!! Here you can learn more about the link to cell technology
