  • LEAK ESTIMATION IN A GAS DELIVERY SYSTEM USING BLOCK LEAST-MEAN-SQUARES TECHNIQUE
    Publication number: 20130116942
    Abstract: A method of estimating leak flow in a gas delivery system is provided that includes determining an average total flow Qtot (or summation or integral of total flow) of the gas delivery system for each of N breaths, determining P?1 and P?2 for each of the N breaths, wherein P is a leak pressure of the gas delivery system, ?1 is a first predetermined value, ?2 is a second predetermined value, and P?1 and P?2 are averages for the breath (summation or integrals may also be used), setting up a system of N equations, one for each of the N breaths, wherein each of the equations has the form Qtot=Gorf.P?1+Gvg.P?2 and uses the determined Qtot, P?1 and P?2 for the associated breath, solving the system of N equations for Gorf and Gvg, and using Gorf and Gvg to calculate instantaneous leak Qleak using Qleak=Gorf.P?1+Gvg.

  • INDUCTANCE COMPENSATION IN A PRESSURE SUPPORT SYSTEM
    Publication number: 20130056006
    Abstract: A system and method for delivering a flow of gas to an airway of a patient (54). The system includes a gas flow generator (52) and a patient circuit (56) comprising a conduit (100) that communicates the flow of gas to a patient. A sensor (62) is configured to measure a rate of the flow gas and generate flow signals based on the measured rate of flow. A controller (64) is operatively connected with the gas flow generator (52) and the sensor (62) and is configured to control a pressure of the flow of gas provided to the patient. The controller (64) receives the flow signals from the sensor (62), determines a rate of change in the flow of the gas, and modifies or compensates the pressure of the flow of gas provided to the patient if the rate of change in the flow of gas provided to the patient exceeds a threshold amount.

  • Reliably transferring queued application messages
    Patent number: 7613831
    Abstract: The present invention extends to methods, systems, and computer program products for reliably and securely transferring queued application messages. Application messages are (e.g.,. binary or text) encoded and then encapsulated in transfer messages, enqueue messages, and dequeue responses such that composable protocol elements used in application messages can be reused in the transfer messages, enqueue messages, and dequeue responses. Transfer message headers are encoded and then encapsulated along with encoded application messages such that composable protocol elements used in transfer headers and application messages can be reused in the store and forward messages. Application messages, transfer messages, enqueue messages, dequeue responses, and store and forward messages can all be configured in accordance with the same messaging protocol, such as, for example, Simple Object Access Protocol.

  • PRODUCTION OF SECONDARY AGGREGATES
    Publication number: 20090104349
    Abstract: Secondary aggregates are prepared from inert waste fines, from, for example, quarrying and combustion processes, using a combination of accelerated carbonation and tumbling, such that aggregate particles composed of successive layers of solid carbonate-based reaction products form a hard aggregate suitable for use in concrete. The process may carried out by loading the starting materials, and if necessary, water into a cylindrical drum that is rotatable about its horizontal axis, and the interior is charged with a carbon dioxide atmosphere, or mounted within a larger vessel that holds a carbon dioxide atmosphere. Aggregates are formed as coatings on core particles as tumbling proceeds, and the coatings are hardened by in situ formation of carbonates by reaction with the carbon dioxide.

  • Water treatment
    Patent number: 7329349
    Abstract: In accordance with the principles of the present invention, methods and apparatuses are provided for practically complete removal of one or more electron acceptors (excluding oxygen) from waters of various origins, while ensuring that an added excess of external carbon is also practically completely removed using biological treatment. A method applies to waters that contain the target electron acceptor and a deficiency of carbon. One application of this method is the practically complete removal of nitrate from domestic wastewater (septic wastewater) while practically completely removing the added excess of external carbon, thus practically eliminating any increase of the biological oxygen demand of the water. Another method applies to waters that contain constituents that are potentially convertible to the target electron acceptor and may contain original carbon.
