  • Patent number: 6041780
    Abstract: A method and apparatus for ventilating a patient wherein the inspiratory positive airway pressure (IPAP) is adjusted as a function of minute volume. The IPAP is gradually adjusted over extended periods of time in small increments to conform the patient's minute volume to a prescribed value. This gentle but effective approach ensures adequate ventilation while minimizing discomfort to the patient thereby rendering the system ideal for treating sleep disordered breathing in the homecare environment.

    Abstract: A wireless velocity detector for a bicycle includes a coil mounted on the wheel hub of the bicycle which generates a rotating magnetic field as the wheel rotates, a receiver mounted on the handlebars that includes a pair of coils that sense variations in the strength of the rotating field as the bicycle moves and generates signals in response to the field variations and a microprocessor which converts the signals into information related to the movement of the bicycle, e.g. speed and distance. A liquid crystal display is used to display the information to the cyclist.
