  • Publication number: 20160267167
    Abstract: A method and a system for analysing in a prescribed domain interests of a persona who interacts with a repository of information containing: items that may embody one or more interests of a persona in that domain, categories that are a collection of all possible interests of a persona relative to that domain, and values that constitute a measure of the quality or quantity prescribed for each interest. A method and a system for analysing in a prescribed domain preferences of a persona who interacts with a repository containing: items that may embody one or more interests of a persona in that domain, relationships between the items, and attribute values that constitute a measure of the quality or quantity prescribed for each relationship.

  • Publication number: 20160000508
    Abstract: A barrier kit for emergency medical technician sterile patient monitoring equipment provides an emergency medical technician (EMT) a variety of sanitary cover barriers to provide adherence to a cleaning regimen, while avoiding patient to patient cross contamination. The sterile kit is contained in a single envelope including a set of sanitary barriers or sheaths of the same material mounted on a cardboard substrate for a stethoscope, a pulse oximeter probe, a necktie protector and an arm wrap cover to prevent a blood pressure monitor cuff from contacting the patient skin with an attached cover for protection against splatter of bodily fluids from one patient to an EMT technician or from one patient to another patient.

  • Patent number: 6571599
    Abstract: A flow generator having use in the provision of CPAP or assisted ventilation treatment is disclosed The flow generator has a turbine for the supply of breathable gas which is driven by an electric motor and an associated motor power supply. The power supply in turn is controlled by a controller. A pressure sensing port measures delivery pressure that is passed to a pressure transducer, the output signal of which is passed to the motor controller. The zero offset of the pressure transducer is automatically calibrated on occurrence of the conditions where the turbine is not operating and no pressure activity is sensed by the transducer. The turbine not operating condition can be determined from Hall-effect sensors integral to the motor.

  • Patent number: 6345619
    Abstract: A CPAP treatment apparatus has a patient mask is coupled to an air delivery conduit. The air delivery conduit is coupled to an impeller and motor, collectively forming a blower arrangement for providing a positive pressure of air to the conduit. A controller receives a signal representing respiratory flow. The controller is operable to cause the blower to supply an inspiratory phase pressure and an expiratory phase pressure. The controller selectively triggers generation of a pressure intermediate of the inspiratory phase and expiratory phase pressures for a period of time as a transitional state upon the first flow threshold being crossed. The controller also selectively triggers generation of a pressure intermediate of the expiratory phase and inspiratory phase pressures for a period of time as a transitional state upon the second flow threshold being crossed.

  • Patent number: 6332463
    Abstract: A method of flow estimation during CPAP treatment is disclosed and involves measuring turbine (32) speed by means of the motor's Hall-effect sensors (80). The equivalent pressure, pest, that would be developed by the turbine (32) for the measured speed if the flow were zero is estimated using a predetermined mathematical function. Coincidentally with the speed measurement and pressure estimation, the delivery tube pressure, pact, is measured by the pressure transducer (42), and from pact together with pest, the difference between the two pressures is calculated, representing an estimation of flow, fest. The flow estimation value can be linearised by the square root device (86), and then filtered by the combination of low pass and high pass filters (90, 92) to derive a filtered flow estimate value, that has the non-respiratory components removed. A method of flow compensation of flow-induced pressure swings also is disclosed.

  • Patent number: 6237592
    Abstract: A flow generator for the supply of breathable gas, which includes an electric motor driving a turbine, control circuitry, a pressure transducer to sense delivery pressure at or remote from said flow generator and whose electrical output is connected to the control circuitry, and sensing means connected to the control circuitry, and wherein the control circuitry is operable to determine from the sensing means whether the electric motor or the turbine are operating and from the pressure transducer whether there is no pressure activity, and if both determinations are satisfied, to accept the output of the transducer as a calibrated pressure offset value representative of atmospheric pressure.
