Speed Circuit is a Formula I racing game published by 3M in 1971, and then republished by Avalon Hill in 1977. Description
Vertically arranged closed circuit wind tunnel with two test sections: one atmospheric (max speed 16 m/s [52 ft/s]), one aeronautical (max speed 55 m/s [180 ft/s]) with possibility to test with open / closed jet. Hypervelocity Wind Tunnel 9 [33] Diameter 1.5 m (5 ft) United States
Imation SuperDisk drive An LS-120 disk. The SuperDisk LS-120 is a high-speed, high-capacity alternative to the 90 mm (3.5 in), 1.44 MB floppy disk.The SuperDisk hardware was created by 3M's storage products group Imation in 1996, [1] with manufacturing chiefly by Matsushita.

Where circuit costs are high and loss of voice quality is acceptable, it sometimes makes sense to compress the voice signal even further. An ADPCM algorithm is used to map a series of 8-bit μ-law or A-law PCM samples into a series of 4-bit ADPCM samples. In this way, the capacity of the line is doubled. The technique is detailed in the G.726 ...
The canopy bridges will be supplemented with measures like speed bumps to slow down traffic and wildlife crossing signs to alert motorists. She hopes to eventually expand to other areas in Brazil.
Part of the Russian–American Telegraph line bearing the single wire of an earth-return circuit, c. 1866. Earth-return telegraph is the system whereby the return path for the electric current of a telegraph circuit is provided by connection to the earth through an earth electrode. Using earth return saves a great deal of money on installation ...
While a typical shape of a teardrop is straight-line tapering, they may be concave. [2] This type of teardrop is also called filleting or straight. [3] To produce a snowman-shaped teardrop, a secondary pad of smaller size is added at the junction overlapping with the primary pad (hence the nickname).
