  • Patent number: 11446457
    Abstract: An oxygen concentrator (100) apparatus and a method thereof implement operations control to efficiently release oxygen enriched gas to reduce potential waste. The control methodology may include generating a profile such as a minimum inhalation flow profile of the user. The profile may be based on a size parameter of the user. The method may determine one or more control parameters characterizing a bolus of oxygen enriched gas based on the generated flow profile. The control methodology may then generate a bolus release control signal, such as for a supply valve, according to the determined one or more control parameters. The oxygen concentrator may then, with the control signal, release and deliver a bolus of oxygen enriched gas for a user such as for reducing waste.

  • Patent number: 11075068
    Abstract: A method and apparatus that ionize vapors for their chemical analysis is described. The new ionizer improves the ionization efficiency by reducing dilution of sample molecules and improving transmission of ions to the analyzer. This is accomplished by a new flow configuration, in which a stream of clean gas focuses the ions towards the analyzer. A deflector prevents the formation of turbulent perturbation, and the ionization maintains a laminar regime without the need for additional separating walls or electrodes. The flow within the ionizer is configured so that contaminants released by the inner walls of the ionizer do not reach the ionization region. The resulting ionizer improves the ionization efficiency, and the background levels for low volatility species. This makes it ideal for the analysis of low volatility species in the gas phase. One application of this ionizer is the analysis of human breath in real time.

Wireless and/or network connectivity can enable remote communication with the controller via a remote console and/or other wired and wireless devices. Embodiments take partial purge usage volumes into account when determining if standing water is contaminated. Partial purge volumes can include volumes shared with other taps. Embodiments can alert users to potential leaks. Embodiments include a volumetric flow sensor at the external inlet shared among a plurality of taps.

  • Patent number: 10118207
    Abstract: An automated water purging apparatus prevents dispensing of contaminated water by volumetrically flushing a standing volume of water between a tap and an exterior inlet as required. Volumetric control of flushing and usage monitoring between flushing events minimize water waste and delivery delays. Embodiments operate in demand and/or periodic modes, and switch therebetween according to a user-specified schedule. A controller and valve can be powered by a battery that is recharged by energy derived from water flow through the apparatus. Wireless and/or network connectivity can enable remote communication with the controller via a remote console and/or other wired and wireless devices. Embodiments take partial purge usage volumes into account when determining if standing water is contaminated. Partial purge volumes can include volumes shared with other taps.

  • Patent number: 10105092
    Abstract: Introduced are methods and systems for monitoring a person's sleeping patterns, and detecting episodes of sleeping disorders such as snoring and sleep apnea. In one embodiment, a sensor strip attached to the mattress monitors the user's breathing, and detects signature frequencies corresponding to snoring and sleep apnea. Once a sleeping disorder is detected, a notification can be sent to a device associated with the user, or the user's bed can be automatically adjusted to alleviate the sleeping disorder.

  • Patent number: 9932429
    Abstract: Poly(ethylene tetrafluoroethylene) (ETFE) polymers having an average molecular weight of at least 300,000 g/mol and a melt enthalpy of at least 57 J/g are provided. The ETFE polymer may include at least one additional comonomer. The ETFE polymer is used to form a porous tape or membrane that has a node and fibril structure. A porous ETFE tape may be formed by lubricating the ETFE polymer and subjecting the lubricated polymer to pressure at a temperature below the melting point of the ETFE polymer. Optionally, the ETFE tape may be expanded at a temperature below the melting temperature of the ETFE polymer to form an expanded ETFE membrane. Alternatively, the ETFE polymer may subjected to heat and pressure without the addition of a lubricant to form a dense preform. The dense preform may be subsequently slit in a length direction and stretched to form a dense ETFE fiber.

  • Patent number: 9895654
    Abstract: The present invention relates to a water removal device, method and system for gas sampling. The water removal device comprises a dehydration cup, a gas chamber, a pressure sensor, a flow sensor, a feedback control unit, a main channel and a sucking pump. The feedback control unit controls the working state of the sucking pump according to monitoring data of the pressure sensor and the flow sensor. The water removal device, method and system for gas sampling have the advantages that a double-channel gas sampling structure is adopted so that liquid water in a gas course can be removed effectively. By the adoption of an atmospheric pressure switch structure, no gas flow will pass through a second channel under normal circumstances, and the utilization of sampled gas is increased.

  • Patent number: 9839755
    Abstract: A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.
