Power Saver Sensor for TVs Printer Friendly Version
I have a son who constantly leaves the TV on when leaving the room. Often it can be on for an hour or more without anyone watching. I propose an infrared/motion sensor similar to burglar alarms be built into the TV to determine whether anyone is watching. If nobody is in the room for more than 2 minutes (or other specified time), the screen drops out (in the same fashion as computer monitors go into power saving mode). The sound remains on but drops out a little later. Finally, the TV goes to standby mode. Of course, if the watcher re-enters the room after only a short absence, the sensor detects this and immediately turns on the screen again.
Reward: Knowing I helped to save the environment and a TV with this capability.

LED based TV Printer Friendly Version
Well... there's CRT monitors, LCD's, now Plasma. I researched on how Plasma screens work, and it says there that each pixel is made of 3 subpixels, with each having the primary colours. Each subpixel is like a small neon light. It has this really small tube filled with neon or xenon, and one side, the glass tube is coated with colourful phosphour that emits visible light when the UV light from the neon gas hits it. Anyways... well i thought that instead of having these thousands of tubes in a huge array on the screen, to modify the LED. Since the LED is really that a small piece of silicon, and what makes it so bulky is the plastic cover that directs teh light. So since the LED has enough brightness, just make it really really small, so it gives off just enough light. Since LED can be red, green and blue, make the entire screen with LED's printed on an array of invisible conductors.
What's the big deal about this? Well Plasma screens use a lot of wattage. And there is a possibility of destroying the pixels, either mechanically, or that the neon or the phosphorus inside degrades. A lot of heat is given off also, and it's kinda scary when u put ur hands behind the screen and u feel all that heat. On the other hand, with the led's, if they are powered corectly, they are theoretically nondistructive, they never fade away or burn. They normal red led uses around 10mA and if the size is decreased that would get close to 1mA or even less. That's my idea, i know that LED panels were made, but they're big and they use full size LEDs, which are not very good for a room size screen. Tell me what you think about it, and if it would be doable. I don't mind any criticizing. That's how i get better.

Multidimensional DVDs Printer Friendly Version
We all know that DVDs work just like a record player except it reads holes or bumps and raised areas with a laser instead of a record needle. If we had a disc and laser reading variations of vibrations of electricity, we then would have unlimited or extremely large amounts of space to put information of movies or computer data on. If the disc was reading electrical signals along with bumps AND dips in grooves we would have two, or more, forms of readable info making it hold more info. It would read the bumps and grooves but, it would read an electrical wobble in it as well.
You know how a DVD can skip and you loose the picture? What if it read those skips as vibration information. It would literally tip and read that difference. So we would have a three-dimensional tip and with the electricity storage surface where the bumps and hills are in, the grooves are read as readable variations. Just a slight tip would mean something to the reader of the electrical output. Like a computer hard drive with bumps and grooves. Two or more forms of info. The electricity could be static, wobbles in the DVD, magnetic or, all three with the usual laser read hills and holes as well.
