    • A system useable in a jet aircraft having installed therein a pressurized oxygen supply which feeds oxygen into the interior of the plane when it flies at high cabin altitudes, the system indicating the changing status of the supply as oxygen is drained therefrom. The system includes a pressure transducer coupled to the supply and means associated with the transducer to determine the lapse rate at which the pressure of the supply is reduced as oxygen is drained therefrom to yield a first signal representing this pressure lapse rate, and to concurrently determine the lapse rate at which the number of liters of oxygen in the supply is reduced as oxygen is drained therefrom to yield a second signal representing the liter lapse rate. These signals are applied to a microprocessor in whose data base is entered the total oxygen inventory of the supply and the oxygen demand of the plane in which the supply is installed. When oxygen is being drained from the supply, the microprocessor calculates and reads out the prevailing supply pressure, the number of liters remaining in the supply, and the time in hours and minutes remaining before the supply is exhausted based on the current rate of oxygen consumption. The invention provides both a method for calculating the oxygen required, as well as a real time monitoring and calculating system for emergency conditions. The invention is applicable to any pressurized gas system, such as for divers, compressed gas cooking or vehicles, therapeutic oxygen, and the like.
    • 一种可用于喷气式飞机的系统,其中安装有加压氧气供应,当氧气在高舱室高空飞行时,氧气供应到该平面的内部,该系统指示当氧气从其排出时供应的变化状态。 该系统包括耦合到电源的压力传感器和与换能器相关联的装置,以确定当氧气从其中排出时供应压力降低的流逝速率,以产生表示该压力流逝速率的第一信号,并同时确定 供应中的氧气升数随着氧气排出而减少的流逝速率,从而产生代表升流速率的第二信号。 这些信号被应用于其数据库中输入供应的总氧气库存和安装供应的平面的氧气需求的微处理器。 当氧气从电源中排出时,微处理器计算并读出当前的供应压力,供应中剩余的电量以及在供电耗尽之前剩余的以小时和分钟为单位的时间,这取决于当前的耗氧速率 本发明提供了计算所需氧气的方法,以及用于紧急情况的实时监测和计算系统。 本发明适用于任何加压气体系统,例如潜水员,压缩气体烹饪或车辆,治疗氧气等。
