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 system was originally known as Apollo, launched in 1971 by United Airlines as their in-house booking system. In 1976, UA began installing Apollo terminals in travel agent offices. Apollo, and the competing American Airlines system Sabre , quickly took over much of the booking market.
To conform to these regulations the gate system must be checked with a calibrated force tester and the full results kept in a technical file for 7 years. If the gate is not tested it does not comply. Most gate kits can be fitted with safety equipment so that these limits are achieved and so cover that part of EN13241-1.
On its time Apollo VP3 was a high performance, cost effective, and energy efficient chipset. It offered AGP support for Socket 7 processors which was not supported at that moment by Intel, SiS and ALi chipsets. In November 1997 FIC released motherboard PA-2012, which uses Apollo VP3 and has AGP bus. This was the first Socket 7 motherboard ...
The engine developed about 1,600 pounds-force (7.1 kN) of thrust, which produced a velocity of 3,200 meters per second from lunar launch, to LOR, and CM docking. [ 7 ] [ 2 ] Lunar ascent by Apollo 17 ascent stage.
The Apollo EMUs consisted of a Pressure Suit Assembly (PSA) aka "suit" and a Portable Life Support System (PLSS) that was more commonly called the "backpack". [3] The A7L was the PSA model used on the Apollo 7 through 14 missions. [4] The subsequent Apollo 15-17 lunar missions, [5] Skylab, [6] and Apollo–Soyuz used A7LB pressure suits. [7]
Apollo-Soyuz was the first crewed international space mission, carried out jointly by the United States and the Soviet Union in July 1975. Millions of people around the world watched on television as an American Apollo spacecraft docked with a Soviet Soyuz capsule.
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.
