A pulse per second (PPS or 1PPS) is an electrical signal that has a width of less than one second and a sharply rising or abruptly falling edge that accurately repeats once per second. PPS signals are output by radio beacons, frequency standards , other types of precision oscillators and some GPS receivers.
The Honeywell Page Printing System (PPS) announced in 1974, is notable because it was the first commercially successful high speed non-impact printer. [1] It could produce output at up to 18,000 lines per minute, [2] where the earlier Xerox 1200 (the first commercially available electro-static printer) ran at 4000 lines per minute [3] and the contemporary IBM 3211 (which was an impact printer ...
Throughput is usually measured in bits per second (bit/s, sometimes abbreviated bps), and sometimes in packets per second (p/s or pps) or data packets per time slot. The system throughput or aggregate throughput is the sum of the data rates that are delivered over all channels in a network. [1] Throughput represents digital bandwidth consumption.
For example, the speed of sound in water is 1,497 m/s, and the human body is about 0.5 m thick, so the PRF for ultrasound images of the human body should be less than about 2 kHz (1,497/0.5). As another example, ocean depth is approximately 2 km, so sound takes over a second to return from the sea floor.
Battery Charging Specification 1.1 specifies that charging devices must dynamically limit bus power current draw during High Speed signaling; [53] 1.2 specifies that charging devices and ports must be designed to tolerate the higher ground voltage difference in High Speed signaling. Revision 1.2 of the specification was released in 2010.
The Xerox 9700 was a high-end laser printer manufactured by Xerox Corporation beginning in 1977. [1] Based on the Xerox 9200 copier, the 9700 printed at 300 dots-per-inch on cut-sheet paper at up to two pages per second (pps), one- or two-sided, that is simplex or duplex, landscape or portrait.
The Rockwell PPS-8, short for "Parallel Processing System, 8-bit", was an early 8-bit microprocessor from Rockwell International, announced in 1974. It had a number of unique design features, which Adam Osborne described as "most unusual... more powerful... also one of the most difficult to understand."
Polyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked by sulfides. Synthetic fiber and textiles derived from this polymer resist chemical and thermal attack. PPS is used in filter fabric for coal boilers, papermaking felts, electrical insulation, film capacitors, specialty membranes, gaskets, and packings.
