The central controller has one point-to-point data communication wire connected to each module. The protocol between the central controller and the modules uses a 5V pulse width encoding as follows: A header that is 4100 μs high and 300 μs low; One pulse per I/O port, i.e. 16 pulses for input modules and 8 pulses for output modules
This has usually been a blotting paper impregnated with cobalt(II) chloride base; Less toxic alternatives include other chemicals such as cobalt-free chloride base and special plastic films. [1] Humidity indicators are an inexpensive way to indicate or quantify moisture content inside sealed packaging. They are available in many configurations ...
GE-600 series The Honeywell 6000 series computers were rebadged versions of General Electric 's 600-series mainframes manufactured by Honeywell International, Inc. from 1970 to 1989. Honeywell acquired the line when it purchased GE's computer division in 1970 and continued to develop them under a variety of names for many years.
The first IHC "Highwheeler" truck had a very simple air-cooled horizontally opposed two-cylinder engine with a 5-inch (130 mm) stroke and a 5-inch (130 mm) bore, and produced around 18–20 hp (13–15 kW).

A properly installed and located hygrostat should be used to monitor and control humidity levels automatically, or a well-informed and conscientious human operator must constantly check for correct humidity levels. A humidity below 50% can prevent water condensation on building materials. [1] A dehumidifier can be used to balance the humidity.
The Military Transport Aviation Command (Russian: Кома́ндование вое́нно-тра́нспортной авиа́ции (ВТА) — Komandovaniye voyenno-transportnoy aviatsii (VTA)) was a major component of the former Soviet Air Forces, active from the Cold War period, through the dissolution of the Soviet Union, to 1998–1999.
Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...
