Experiments show that in a typical off-the-shelf DRAM chip, only a few weak cells really require the worst-case 64 ms refresh interval, [14] and even then only at the high end of its specified temperature range. At room temperature (e.g. 24 °C (75 °F)), those same weak cells need to be refreshed once every 500 ms for correct operation.
In automatic (regular or interrupted) scanning, the indicator scans in the preset pattern on its own and item selection occurs when the scanner hits a switch. [5] [7] In step scanning, the user controls each movement (or step) of the scanning indicator through its preset pattern by hitting a switch. To select an item, the AAC user hits a second ...

[1] Large scale book scanning projects have made many books available online. [2]
When activated, the fail-safe circuitry forces all control outputs to safe states (e.g., turns off motors, heaters, and high-voltages) to prevent injuries and equipment damage while the fault persists. In a two-stage watchdog, the first timer is often used to activate fail-safe outputs and start the second timer stage; the second stage will ...
Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
