Does anyone know the name of this toy? I had this toy when I was a kid (late 80s early 90s) and I can't remember what it was called. It was a headset that came with books (one on dinosaurs and one on the planets) and expansion cartridges. It was grey, purple and red. And if you pull out an expansion cartridge while it was on the head set would say ''PLEASE PUT IN THE EXPANSION CARTRIDGE.'' You could also choose the voice the headset used. I searched google for it but have had no luck. Hopefully someone can help me on my quest..

Dear Sir/Madam,

How can I make HD Television broadcast original type TV show? I mean the original channel not the HD new channel? The most important to have a channel for a video recorder so that I can watch video tape.

Yours truly,

Miss Yellow River.

This is code for parallel interference cancelltion in ds cdma using matrix algebraic approach.

Please check the code and let me know if I am doing any mistake. Also I need to apply slow and fast rayleigh fading in this model.

The rcd signal is R = SAB + N

where R,S,A,B are matrices

The matlab code is given below :

I use Dish TV. There is a feature under which I group my favourite channels under numbers 1,2,3,...I could make the groups of my favourite channels as per instructions given in the User's manual, but I do not know how to get the channels in a certain order of priority. For instance, I want X channel first to appear, then Y, then Z. But what I find is the priority order is disturbed although the channels selected do appear. How could I get the channels in a particular priority order?

I got the sims 3 and my video card is out of date. I went down to the computer store and they said I needed a DSI Video Card ( not DSI Express, computers to old) but they did not have any. I called another computer store and they said even with a DSI card, the game would not run. I was wondering if he was right. I have a Windows XP Home Edition DELL.

I have an Audiovox Portable DVD player Model #D1788, that is less than a month old. It has worked wonderfully until tonight. I turned it on, fully charged with a clean DVD and pushed the screen to a 90 degree angle and the screen went white with lines running through it. I have sound and if I push it past the 90 degree angle it works fine. What happened?
