| Joey, 12th grade | My idea for a future application of waveform synthesis in cell phone applications would be a more complex version of "the clapper". The idea behind the clapper is that a sound of a certain volume would control the power output through a certain device. Using waveform synthesis in a cell phone, we can make the phone output waveforms beyond human hearing. These waveforms would be specifically combined to give a unique sub- or super-sonic tone that would activate or deactivate various lights, appliances, or other systems in a home. Fully integrated, it would be a remote control for the world. Because of the limited range of such frequency sounds, they would be perfect for a small space environment. They would likely not interfere with, say, a nearby house. Each item to be activated could be programmed to recognize certain tones meaning certain things. For instance, a tone using 7.1 ; 14.2 ; and 21.3 Khz frequencies could be set to turn on the coffee maker, the toaster, and the microwave to setting "30 seconds" The biggest advantage of cell phones is there mobility, if you needed someone else to turn on these items, you could send their phone the necessary tonal information. Also, using the same activation technology, you could solve much of the gun control situation. Similar to a fingerprint gun, you could manufacture ones whose safety turns off only on hearing the right tone, which would be send when a password is entered in the officer's cell phone. | |
| Luke, 12th grade | One problem that has plagued
cell phones for quite some time is, simply, how irritating they can be. A
large part of this annoyance springs from the rings. Some phones have the
simple, screeching ring. Others, a screeching-ring version of Beethoven or
Eminem. Either way, when somebody near you gets a phone call, it makes you
grit your teeth. I think a good advance that has yet to be made would be
to improve the quality of these "ringtones" greatly. Instead of an
incessant, five-second loop of Beethoven's fifth, composed entirely of
beeps, how about an actual recording OF Beethoven's fifth. The volume of
the sound could increase with each "ring", or simply increase gradually.
Either way, the phone would keep its effectiveness in relaying the
information that "you have a call," without the screechy, irritating
noise. Making this take advantage of an mp3 file would be easiest from the
consumer's point of view, but would require some processing power within
the phone. Using uncompressed music data, alternately, would require some
storage space on the phone. The size and time of the sound would thus have
to be limited, though I think an effective ring-length song could be
stored on the average-sized phone of today. > See Polyphonic cell phones for what is going on right now! |

| Arish, 12th grade | The human ear has the ability to pick up a specific range of frequencies. However, there are an infinite number of frequencies that the human ear cannot hear. I propose to use these frequencies to distinguish people and their identity. This process will be more cost efficient then actual inferred transfers. Let’s say you wanted to buy a coke from a coke machine. Rather than bother with change, your phone could pay for it by emitting a frequency that would trigger the coke machine to charge your account. It would make the process much easier and simpler. I would add to phones the ability to play any form of multimedia with wireless plugs inserted into your ears to give an amplified and surround-sound feeling. Scientists believe that there are some sound waves that actually stimulate the nerves in your cranium causing you to relax more during tense times. This modification would help the people who are constantly bombarded with stress. | |
