The Apollo flight computer was the first computer to use silicon IC chips. [15] While the Block I version used 4,100 ICs, each containing a single three-input NOR gate, the later Block II version (used in the crewed flights) used about 2,800 ICs, mostly dual three-input NOR gates and smaller numbers of expanders and sense amplifiers.
The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana. [1] Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.
The docking mechanism of the Apollo was a "probe and drogue" system designed to allow the Apollo Command/Service Module (CSM) to dock with the Apollo Lunar Module.The same system was later used for the Skylab 2, Skylab 3 and Skylab 4 CSMs to dock with the Skylab space station, and the Apollo–Soyuz Test Project CSM to dock with a Docking Module adapter which allowed docking with the Soyuz 19 ...
The backbone of any electric gate, whether automatic or not, is the electric gate motor, two distinct motor types exist hydraulic, or electromechanical. This is the electric device which actually enables the electric gate to open and close without having to manually push the gate.
The Apollo 1 flight was cancelled after a cabin fire killed the crew and destroyed their command module during a launch rehearsal test. Corrections of the problems which caused the fire were applied to the Block II spacecraft, which was used for all crewed spaceflights. Nineteen CSMs were launched into space.
The old and newer version are a masterpiece of state of the art engineering and both are very well built. For example there's a diagnostic connector at the back panel for quick troubleshooting. The display unit is eventually a rather 'dumb' device. The original display unit is 'just' a display and a keypad.
The Apollo reservation system was used by United Airlines until 3 March 2012, when it switched to SHARES, a system used by its former Continental Airlines subsidiary. Apollo is still used by Galileo International (now part of Travelport GDS) travel agency customers in the United States , Canada , Mexico , and Japan .
Failure is not an option is the tag line of the 1995 film Apollo 13.It is spoken in the film by Ed Harris, who portrayed Gene Kranz, and said [2] [3]. We've never lost an American in space; we're sure as hell not going to lose one on my watch!
