  • Publication number: 20240337685
    Abstract: A receiver comprising a magnitude correction circuit to receive an electrical signal defined by a phase. The electrical signal is a combined electrical signal comprising a first signal and a second signal. The magnitude correction circuit comprising a detector to generate a control signal proportional to received power of the second signal and an error amplifier coupled to the detector to compare a reference voltage against an output of the detector to determine an amplification or attenuation of the second signal based on a drift of the electrical signal. The receiver further comprising a variable gain amplifier coupled to the magnitude correction circuit to generate a compensated electrical signal based on the amplification or attenuation of the second signal determined by the magnitude correction circuit and a de-modulating mixer coupled to the magnitude correction circuit, the de-modulating mixer to mix a phase compensated signal and the compensated electrical signal.

  • Patent number: 8327845
    Abstract: An inline vaporizer disposed in a carrier gas line vaporizes a fluid and adds such vaporized fluid to a carrier gas that flows within the carrier gas line. The vaporizer includes a reservoir or wick that transfers a fluid to a vaporizing element that is adjacent to the reservoir or wick. The vaporizer releases a vapor into the carrier gas line so that the carrier gas flows past the vaporizer to form a vapor and carrier gas mixture.

  • Publication number: 20060065267
    Abstract: A mouthpiece which is attachable to nebulizer is configured to enhance the flow of gas carrier through an aerosolization portion of the nebulizer. The mouthpiece has a hollow body attached to a drug delivery conduit. The drug delivery conduit has a drug delivery port in one end. The interior of the hollow body is configured to efficiently direct gas carrier flow into the aerosolization chamber of the nebulizer to allow better mixing of the aerosolized substance and the gas carrier before the gas carrier exits the nebulizer. A cap may be removable and replaceable from a hollow body to allow use of the nebulizer in both a breath enhanced setting and a ventilator setting. Further, a cap may be configured to reduce or eliminated spillage from the mouth piece.

  • Patent number: 6776159
    Abstract: An oscillatory positive expiratory pressure respiratory therapy device which may be incorporated into the expiratory limb of a ventilator circuit. Accordingly, this device allows a patient on a ventilator to be subjected to positive expiratory pressure (PEP) therapy combined with airway oscillation and intermittent air flow acceleration while allowing the oscillatory PEP respiratory therapy treatment to be bypassed without interrupting the integrity of the ventilating circuit once the device has been installed in the ventilator circuit. In this manner, all expiratory air in the ventilator circuit is accounted for, the expiratory air volume may be accurately monitored and the ventilator circuit does not have to be broken for insertion or removal of the device.
