Your Questions About Bluetooth Technology Uses

Ruth asks…

What is a good, small, computer mouse brand?

I use to use Gear Head to photoshop and it worked really nicely because it was light, small, and simple to use. I'm looking for a mouse brand with similar qualities. I don't want a high tech mouse for gaming purchases, just one that is able to perform the tasks of a basic mouse. Thank you!

What is bluetooth and how does it work?

It's wat you get when you eat too many blueberries.


Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecoms vendor Ericsson in 1994,[1] it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.
Bluetooth is managed by the Bluetooth Special Interest Group, which has more than 14,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics.[2] The SIG oversees the development of the specification, manages the qualification program, and protects the trademarks.[3] To be marketed as a Bluetooth device, it must be qualified to standards defined by the SIG. A network of patents are required to implement the technology and are only licensed to those qualifying devices; thus the protocol, whilst open, may be regarded as proprietary.

How do you pair stereos, other laptops and tvs using Windows 7?

There was a commercial on today during football that indicated you can play music on your stereo from your laptop wirelessly and play movies from your laptop to your tv wirelessly. Is this some kind of new technology that you would need on your stereo or tv or is it just bluetooth? How does it work?

How do you pair stereos, other laptops and tvs using Windows 7?

dknol answers:

They are showing other computers running windows 7 being paired. If u have multiple windows 7 pcs they can be paired to play music, video on each other. U can hook a computer up to a tv and watch the video or hook it up to a stereo to hear music on it. It uses your home wifi/internet to do this.

Sandra asks…

What would be the Best type of signal to use for an Underwater Device?

What would be the best type of signal for an underwater device.

For Example: If there was a waterproof Electronic Device and a waterproof wireless remote control for this device what would be the best type of wireless signal technology (such as: bluetooth, ultra sound…) for this device?

dknol answers:

The first two answers are correct. Sound waves propagate well underwater from very low frequencies, below audio, right up to very high ultrasonic frequencies of a few hundred KHz. The only other way to communicate underwater is ELF (extremely low frequency) radio, below 30 KHz. This is very expensive and requires very long aerials. It is used for Omega communication with nuclear subs. It works worldwide. Ultrasonic sound waves carry much more information; with data compression they could even give you video, but the range is no more than about 100 km; Cetaceans like whales use sound waves up to a few km. At a depth of a few hundred metres there's an ocean layer called the SOFAR channel which can channel sound waves a bit further than this, but seven Omega stations cover the globe.
