A method of purifying a target fluid containing one or more impurities, the method includes providing the target fluid to a vessel having an adsorbent material located therein, where the absorbent material is a metal organic framework (MOF) or a porous organic polymer (POP), preferentially adsorbing either the target fluid or at least one of the one or more impurities on the adsorbent material, and venting the target fluid from the vessel if the impurities are preferentially adsorbed on the adsorbent material or venting the one or more impurities from the vessel if the target fluid is preferentially adsorbed on the adsorbent material.

A method of providing a breath to a human patient having a patient connection connected by a patient circuit to a ventilator device. The method includes delivering both a bolus of oxygen and breathing gases including air to the patient circuit. The patient circuit conducts the bolus of oxygen and the breathing gases to the patient connection. The breathing gases are delivered before an end of the inspiratory phase of the breath. The bolus may be delivered at or before a beginning of an inspiratory phase of the breath, and the delivery of the bolus may be terminated before the end of the inspiratory phase of the breath. The bolus and breathing gases are delivered to the patient circuit via different ventilator connections that isolate the bolus from the breathing gases before they enter the patient circuit.

An active exhalation valve for use with a ventilator to control flow of patient exhaled gases. The valve includes a patient circuit connection port, a patient connection port, an exhaled gas port, a pilot pressure port, and a valve seat. The valve further has a movable poppet with inner and outer bellows members and a bellows poppet face. An activation pressure applied to the pilot pressure port extends the bellows members to move the poppet face into engagement with the valve seat and restrict flow of patient exhaled gases to the exhaled gas port, and the reduction of the activation pressure allows the bellows members to move the poppet face away from the valve seat and out of engagement with the valve seat to permit flow of patient exhaled gases to the exhaled gas port, thereby controlling the flow of patient exhaled gases from the valve.

An evaporative emission control canister system comprises an initial adsorbent volume having an effective incremental adsorption capacity at 25? C. of greater than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, and at least one subsequent adsorbent volume having an effective incremental adsorption capacity at 25? C. of less than 35 grams n-butane/L between vapor concentration of 5 vol % and 50 vol % n-butane, an effective butane working capacity (BWC) of less than 3 g/dL, and a g-total BWC of between 2 grams and 6 grams. The evaporative emission control canister system has a two-day diurnal breathing loss (DBL) emissions of no more than 20 mg at no more than 210 liters of purge applied after the 40 g/hr butane loading step.

Some implementations can include a desiccant breather having an inner pipe having a top portion with a lip extending radially from the inner pipe, the inner pipe having a threaded portion and a top connector. The desiccant breather can also include an outer pipe having a diameter sufficient to accommodate the inner pipe, the outer pipe having a bottom connector and a cap. The desiccant breather can further include a desiccant breather body portion having a cavity configured to hold desiccant material. The lip of the inner pipe can have a diameter equal to or greater than a diameter of the outer pipe.

An air separation system includes an air separation module configured to receive feed air and separate the feed air into nitrogen-enriched air and oxygen-enriched air, a nitrogen-enriched air line for transporting the nitrogen-enriched air from the air separation module to a fuel tank for inerting, an oxygen sensing line connected to the nitrogen-enriched air line, a gas adsorption filter located in the oxygen sensing line, and an oxygen sensor downstream of the gas adsorption filter in the oxygen sensing line.

The present invention relates to a process cycle that allows for the stable production of mid-range purity oxygen from air, using traditional system designs. Typical cycles have a limited production benefit when generating O.sub.2 at lower than 90% purity, however they suffer a production loss at higher purity. The process cycles of the invention are capable of producing significantly more contained O.sub.2 at a lower purity. In addition to enhanced production capacity, lower power consumed per mass of product and more stable product purity and flow are realized by the process of the invention compared to traditional alternatives.

Field of the Invention/Idea:

The present invention/idea is the brain trust of Rhonda M. Tiller. She received this concept in a dream of how to eliminate odors associated with garbage containers, cans, and other odor producing items.

Description of the Related Market:

We recognize that some companies have devised sprays, clip-on, and insert bags for reduced odor control; but these products simply mask the odor. There is a real need to fill this void in the marketplace for odor elimination.

Summary:

1. The first usage is shown to the commercial side of this invention/idea and will be introduced to that segment of the market which already exists as a new concept for customers in order to set this project apart from its competition.

2. The second usage will be packaged and marketed to the domestic side for use in the garbage containers designed for home or office places of conveniences.

A pressure swing adsorption oxygen generator to separate oxygen from air for use with a pressure source generating a high pressure and a low pressure. The pressure swing adsorption oxygen generator includes an adsorption bed having a bed of nitrogen absorbent material; and a multi-position rotary valve for controlling pressure swing adsorption of the adsorption bed, and being couplable to the pressure source for fluid communication therewith and in fluid communication with the adsorption bed. The rotary valve includes a cam having first and second rotary positions, in the first rotary position of the cam the rotary valve communicating high pressure generated by the pressure source to the adsorption bed and in the second rotary position of the cam the rotary valve communicating low pressure generated by the pressure source to the adsorption bed.
