Invention Flashcards
“the cycle” Tim Wu
Period of openness
Amateur radio, then a company sees the market and takes over, and become lazy, leading to openness for more amateurs and reabsorption of amateurs
open to close system (cycle) leads to missing opportunities
Malcolm Gladwell
The author talks about invention of the television
writes about small inventions/inventors
Multiples
The same invention is being created by various people around the world
Due to the belief that inventions are inevitable to happen (in the air) but will eventually be created
Patent
Protects ideas, lasts 20 years
Used to be based on the time of invention, but now based on who filed the patent first
Promotes research and development
Fake monopoly on ideas
Alexander Graham Bell
Inventor, hates Western Union monopoly
Patented the telephone in 1876, sued 600 times about the telephone
The telephone was publicly shown at the 1876 World Fair, different from the patent picture
Johann Whip Reis
1861, German
Competition against telephone
Elisha Gray
Was the first in line to file the patent of the telephone, but Bell filed the patent first due to knowing the system, and someone in the patent office
Thus, leading to being rejected for the patent
Daniel Drawbaugh
From Philadelphia, invented the telephone in 1866 or 1867 (way before Bell, but doesn’t patent it until later)
The inventor is not an innovator, didn’t know the system
Didn’t file for patent until 1880
Antonio Meucci
Same laboratory as Bell, inventing the telephone
In 2002, there was a case by the US government about how Meucci says he invented the telephone and that it got stolen, believing that it could have been Bell’s team
Yet, wasn’t decided since the Representative believed Meucci and Senate believed Bell
Edwin Armstrong
invented the FM radio
fixes radio by creating an FM radio- which modulates the frequency
Takes his own life after trying to sell FM radio
David Sarnoff
He worked with Armstrong about radio due to it not sounding clear, the RCA company
Scared due to the original radio using amplitude, doesn’t want to sell FM radio, and would obliterate Armstrong if he uses and tries to sell FM radio
Starts to use FM radio after Armstrong dies, but doesn’t give Armstrong credit
Armstrong’s wife continues to fight for her husband and wins
He wanted to be the leader of the television
Amplitude modulation
Used by the original radio by varying its amplitude
Audio signal is combined with a carrier wave
Frequency modulation
FM radio
The encoding of information in a carrier wave by varying the instantaneous frequency of the wave
Photoconductivity
Cells that take light
Increase in a material’s electrical conductivity when it is exposed to light
Raster scanning
A method of capturing and displaying images in a rectangular pattern, line by line
Used in TVs and monitors
Paul Nipkow
Part of the race for the creation of the television
Uses disks with holes to see images and project them
Vladimir Zworykin
Works with David Sarnoff
Philo T. Farnsworth
Main competitor against Sarnoff about television
Inventor and fighter against the RCA corporation for the invention of the television
Wants to be the next Edison and Bell, had access to science fiction magazines and journals
Has a flash of insight when plowing the dirt in his family farm, and how the lines can be done to trick the brain to see the image projected on the screen
Talks to his teacher about his idea, works in the Navy, but quits due to not wanting his invention being owned by someone else
Looks for inventors, companies look for him (RCA), invites his competitors to his lab, then they patent the television
Farnsworth sued RCA and had to prove that it came up with the invention first, does it by looking for his old teacher who he gave a picture of his idea
Hugo Gernsback
writes/edits science fiction magazines
had inventions like a version of VR
Image dissector
Sarnoff & Zworykin create their own version, allowing for TV to work
A camera tube that converts light into an electrical signal
John Logie Baird
Farnsworth goes to work for him after everything with the television
