Abstract: A device for accurately adjusting the position of a sensor unit relative to a driving member. The driving member is moved by a coin dispensed by a coin dispenser. The sensor unit is mounted on a movable base plate that is positioned on a fixed base plate attached to the coin dispenser. The relative position of the sensor unit to the driving member is adjusted by a screw unit that can adjust the position of the movable base plate relative to the fixed base plate. A fixing unit secures the movable base plate from moving relative to the fixed base plate once the desired sensor unit position is selected using the screw unit.

Abstract: A nasal adaptor device and seal for delivering gases under pressure to the nasal airway of an individual including an aerodynamically contoured manifold to receive gases from an inlet and to divide the gases for flow to a pair of flange members, preferably having a non-spherical curved "egg-shaped" surface, which members are, complementary to the nares of an individual without cannulating the nares to provide a seal to withstand positive pressure of gases to be distributed to the nasal airways. The devices and nares seals of this invention are especially useful in treatment of obstructive sleep apnea and in ventilation of individuals for whom positive pressure ventilation is indicated.
