A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
During the EVA they breathe 100% oxygen in their spacesuits, which operate at 4.3 psi (0.30 bar), [88] although research has examined the possibility of using 100% O 2 at 9.5 psi (0.66 bar) in the suits to lessen the pressure reduction, and hence the risk of DCS.
In the case of the Tx 20/40, in a 230 bar cylinder, this would be 230 bar x 40% = 92 bar (or for a 3,000 psi fill, it would require 3,000 x 40% = 1,200 psi of helium). The amount of oxygen is more difficult to calculate, as it is derived from two sources, the added oxygen and the air top-up.
manual reset; local control; muting; response time; safety-related parameter(s) fluctuation, loss and restoration of power sources; Each safety function identified in the risk assessment is assigned a required Performance Level (PL r) based on the intrinsic risk determined through the risk assessment. The intrinsic risk is the risk posed by the ...
Oil and gas separators can operate at pressures ranging from a high vacuum to 4,000 to 5,000 psi. Most oil and gas separators operate in the pressure range of 20 to 1,500 psi. Separators may be referred to as low pressure, medium pressure, or high pressure. Low-pressure separators usually operate at pressures ranging from 10 to 20 up to 180 to ...

An example of this is the 2005 Helios Airways Flight 522 crash, in which the maintenance service left the pressurization system in manual mode and the pilots did not check the pressurization system. As a result, they suffered a loss of consciousness (as well as most of the passengers and crew) due to hypoxia (lack of oxygen).
For example, in the x86 architecture, asserting the RESET line halts the CPU; this is done after the system is switched on and before the power supply has asserted "power good" to indicate that it is ready to supply stable voltages at sufficient power levels. [2] Reset places less stress on the hardware than power cycling, as the power is not ...
