Time pressure gauge
Encyclopedia
A time pressure gauge is an instrument that digitally displays pressure
Pressure
Pressure is the force per unit area applied in a direction perpendicular to the surface of an object. Gauge pressure is the pressure relative to the local atmospheric or ambient pressure.- Definition :...

 or psi) into simplified duration format (time) creating greater precision and efficiency. While a pressure gauge indicates a general unit amount, only a time pressure gauge accounts for varying consumption and capacity in relation to time remaining.

Applications

Time pressure gauge applications are universal. Welders using oxygen
Oxygen
Oxygen is the element with atomic number 8 and represented by the symbol O. Its name derives from the Greek roots ὀξύς and -γενής , because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition...

 and acetylene
Acetylene
Acetylene is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in pure form and thus is usually handled as a solution.As an alkyne, acetylene is unsaturated because...

 can plan more efficiently if they know the energy duration due to varying consumption in cutting techniques. A nurse concerned that a patient may run out of oxygen can monitor the workload more efficiently by knowing how much time is remaining rather that how much pressure is left.

Scuba divers could determine the length of time they could remain submerged. A pilot could manage supplemental oxygen flow rates of an aircraft
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

Safety

Using a time pressure gauge is also very valuable in dangerous scenarios. Imagine a firefighter

Breathing
Breathing is the process that moves air in and out of the lungs. Aerobic organisms require oxygen to release energy via respiration, in the form of the metabolism of energy-rich molecules such as glucose. Breathing is only one process that delivers oxygen to where it is needed in the body and...

Reducing Carbon Footprint

The use of a time pressure gauge provides for better planning with any instrument that emits carbon

 gas through varying consumption rates determined by pressurized contents. Efficiency is maximized by understanding energy requirements in time. One such example would be something as simple as a gas grill. Operation of a gas grill with all burners on can observe tangible results (time reduction) by turning the gas control to low or by shutting off one burner. Seeing the increase in time will automatically indicate an increase in energy saving. Most notably the time pressure gauge could reduce carbon emissions in all air travel through increased fuel efficiency, while also reducing fuel cost.Furthermore, recently the airline industry is under pressure to reduce carbon emissions globally, and instruments such as the time pressure gauge could spearhead this movement.

Current Software Technology

Time pressure gauge technology is relatively new, and not fully in widespread use. However, the software technology it uses is more integrated. A comprehensive oxygen planning program developed by Aeronautical Data Systems Inc. for the airline industry exists and is in use with over 20 corporate flight departments.
