The base station and the mouse are paired. they have unique key algorithms. You might find on the mouse and base station (*Make dependent) small buttons that you can use to "retrain" the connection, this basically means making a new key if the old key seems to allow for nearby devices to interfere with the connection.
If it doesn't have a reset button then it will use a algorithm that rotates the keys every time the mouse stimulates a signal, each update from the mouse will attempt to connect the mouse with the base station and the keys will rotate until they are paired, once paired they will work similar to how a session key works with a encrypted tunnel, keeping a live connection for as long as you use the mouse.
If it wasn't a wireless mouse and use have a USB connection then the mouse will likely use a Universal Plug and Play method of installing the drivers. This means the mouse actually identifies it's make and model to the operating system and will either use predefined drivers that came with the operating system or attempt to gain them from an online resource or other form of media.
USB mouses emulate the old Serial methods of connection that require IRQ's to be assigned, albeit the IRQ assigned might well be used by all the USB devices connected.

You'd be better off checking the "Class of laser" under the Laser Safety entry of Wikipedia
Optics mice should fall in the CLASS 1 category, which suggests it shouldn't be able to produce enough exposure to cause retinal damage if accidentally viewed, however I still wouldn't suggest staring at it, purely for the sake that any alteration outside of the design parameters (like an energy surge) could make it breach CLASS 1.
You will usually find one of those CLASS warning stickers applied to CD/DVD/Blu-ray roms.

This question is slightly off-topic but related.
Is there any way to amplify the range of a wireless keyboard. I think it would be nice to type reports in front of the televison with just my keyboard.
I have a laptop and a tiny 1.1 pound notebook I can also use, but The keyboard is nice and I got used to using a long USB extension chord once before and it seemed good enough. I arrive back to a screen of typos and spelling errors, but nothing that cannot be polished. I guess I like the way my laptop stays on and in mode. With the laptop I am constantly opening it and pressing power button before i can type.
Sorry for long drawn out reasonings, but it is an odd request for info.

kwhilborn - the only real way to extend the range beyond what it is would be to buy a keyboard designed for such a range... that or use a series of USB cables to extend the receiver into the room you are in. Most mice use a very low-power transmitter to save battery life - I know at work we sell a Logitech RF remote that is able to transmit from about two rooms away - however, you only get about two to three days of use from it's rechargeable Li/Ion battery pack (per charge) because of it.

Thanks I will look into it. The keyboards I have seen have been more like 30 inch range. Perhaps that is what you were thinking.
I'm thinking I can buy a wireless usb extension that will solve problem.
Will google keyboards before i do though . ty.

Thanks. Netflix is awesome. I have Fiber Optic television (do i call that cable?) and I also have netflix. Netflix is great for the first 6 months and then you have seen most of it, but $8 month is good.
I will look at range of keyboards. The ones I have are much shorter range. perhaps so they don't interfere with other computers in an office environment.
