Digital Video Recorder (DVR)Digital Video Recorders (DVR’s) record digitally, to disk or flash memory, rather than analog recording to tape. This allows end-users to quickly fast-forward, rewind, and jump to a section of a recording rather than slowly searching. Tivo and ReplayTV both launched DVR’s at the 1999 Consumer Electronics Show. As they did with videotapes, broadcasters and … Continue reading "Digital Video Recorder (DVR)"
Time-Sharing/Multitasking ComputerEarly Computers Early computers stored programs and data on punch cards. Most cards contained 80-characters, which is why early terminal programs were typically 80-characters per line. Punch cards are exactly what they sound like, physical cards. Each card is one line of a computer program or one piece of data. As users typed, a machine … Continue reading "Time-Sharing/Multitasking Computer"
Coke Fueled Blast Furnace / Pig Iron1709 Abraham Darby used Coke instead of coal to fire blast furnaces, making the production of iron from pig iron (a weak iron), much more economical. Coke burns significantly hotter than coal which, combined with his new design to concentrate the heat, his factory was significantly more efficient than prior methods. He created the Bristol … Continue reading "Coke Fueled Blast Furnace / Pig Iron"
The Role of Education in Automation TechPart I, “Automation Armageddon: a Legitimate Worry?” reviewed the history of automation, focused on projections of gloom-and-doom. Part II, “Automation: Robots in Real Life” reviewed how robots are ubiquitous and create jobs. My first real job was creating a print estimating and production control system for five print plants scattered around the US. Each had … Continue reading "The Role of Education in Automation Tech"
Console Gaming SystemsConsole game systems are specialized computers that play games. Ralph Baer came up with the idea of a video-game system that connects to televisions in 1966. Magnavox agreed to manufacture and distribute his seventh prototype, in 1971, branded the Odyssey. Magnavox sold about 350,000 units, at the then steep price of $100, before discontinuing it … Continue reading "Console Gaming Systems"
Automobile Assembly LineAssembly lines leverage standardized parts to break auto assembly into discrete components, each that can be done by a small number of people (often just one). Standardized parts evolved into standardized jobs. Ransom Olds, inspired by a musket factory that used standardized parts with workers each focused on one part, created the first auto assembly … Continue reading "Automobile Assembly Line"
Ethernet NetworkingEthernet is a computer networking protocol. Before Ethernet, computers were connected using a hodgepodge of various systems, a digital Tower of Babel. Background Bob Metcalfe invented Ethernet at Xerox PARC. However, Xerox failed to commercialize the technology. Metcalfe left and worked on his own Digital (see minicomputers) and Intel to set Ethernet as a networking … Continue reading "Ethernet Networking"
Computer Assisted Design (Sketchpad)“The cinema camera doesn’t make movies; it allows movies to be made. It’s the creative people who make it real to people.” Ivan Sutherland Computer Assisted Design (CAD) uses mathematics to do the geometry and calculations necessary to draw and design. CAD is faster and more accurate than hand drawing. Sutherland’s “sketchpad” software, part of … Continue reading "Computer Assisted Design (Sketchpad)"
EmailRay Tomlinson would likely have lived in anonymity but for Shiva Ayyadurai, the man who claimed to invent email as a 14-year-old child. Ayyadurai is certainly bright, a Fulbright scholar who holds four degrees from MIT. He ran against Sen. Elizabeth Warren in the 2018 Senate race, attracting 91,710 votes. Ayyadurai’s claim as the inventor … Continue reading "Email"
Electronic Stock Exchange (NASDAQ)History In early stock markets, traders offered and accepted bids for stock prices to one another. People would stand in a stock exchange and literally yell out stock symbols and prices. Buyers would purchase blocks of stock. This system was slow and expensive. Only high-level bankers had access to the people on a stock trading … Continue reading "Electronic Stock Exchange (NASDAQ)"
PhonographWe, the editors of innowiki, have reviewed thousands of inventions. We’ve read through countless idea, rejecting the vast majority not because they lacked merit but because they didn’t rock the world. Background Of the innovations we accept there are very few who have more than one invention. Granted, the raw number of innovations does not … Continue reading "Phonograph"
Complementary Metal-Oxide-Semiconductor Chips (CMOS)The magical ability to power your mobile phone, tablet, and computer comes from a CMOS chip. These chips require minuscule amounts of power compared to other types of computer chips. They are as small or smaller than other types of chips. However, despite these advantages, it took decades for the technology to gain traction. Fairchild … Continue reading "Complementary Metal-Oxide-Semiconductor Chips (CMOS)"
AirplaneWilbur and Orville Wright invented the airplane with their first flight in 1903. Urban myth describes an easy story where the bicycle mechanic brothers built an airplane from spare parts. In reality, the innovation was a long, slow, methodical, and extremely dangerous project. Background People had been building various forms of fixed-wing gliders for years. … Continue reading "Airplane"
Spread Spectrum Frequency Hopping1941 Hedwig Eva Maria Kiesler (Hedy Lamarr)George Antheil Spread spectrum frequency hopping synchronizes devices to speak over changing frequencies. The technology jumps from one frequency to another in a predetermined but predictable manner so that the sender and recipient can change simultaneously. Lamarr and Antheil created the technology to contribute to the WWII effort, though … Continue reading "Spread Spectrum Frequency Hopping"
Cash RegisterCash registers help deter theft and led to modern bookkeeping. Ritty was a saloon owner who had problems with employee theft. He invented and patented the cash register, calling it the “Incorruptible Cashier” and created a company to sell it. There was little interest and he tired of simultaneously running two businesses, one manufacturing and … Continue reading "Cash Register"
