A blower includes a housing including an inlet and an outlet, a bearing-housing structure provided to the housing and adapted to rotatably support a rotor, a motor provided to the bearing-housing structure and adapted to drive the rotor, and an impeller provided to the rotor. The bearing-housing structure includes a bearing shaft having a bearing surface that rotatably supports the rotor. The bearing shaft provides only a single bearing of the non-ball bearing type for the rotor.

A control system provides automated control of gas washout of a patient interface, such as a mask or nasal prongs. A gas washout vent assembly of the system may include a variable exhaust area, such as one defined by gears, radial exhaust revolvers and/or flow diverters for a conduit having a variable gas passage channel. The vent assembly may be attached substantially near or included with the patient interface. An actuator of the assembly, such as a solenoid, motor or voice coil, manipulates the vent assembly. The actuator may be configured for control by a processor to change the exhaust area of the vent assembly based on various methodologies including, for example, sleep detection, disordered breathing event detection and/or leak detection.

Disclosed is an actuator for use with a disk drive having a coil assembly including a bobbin to aid in heat convection from the coil of the coil assembly. The actuator includes a body portion for pivotally coupling to the disk drive and an actuator arm cantilevered from the body portion for supporting a head gimbal assembly (HGA). The actuator further includes a coil assembly having a fork, a coil, and a bobbin. The fork is cantilevered from the body portion in an opposite direction from the actuator arm and includes a pair of opposed prongs to mount the coil and the bobbin therebetween. The bobbin includes at least two opposed fins to aid in the convection of heat from the coil.

A disk drive including a disk drive base. The disk drive further includes at least one rotatable disk including a disk surface extending to an outer disk edge. The disk drive further includes a head stack assembly rotatably attached to the disk drive base in operable communication with the disk. The disk drive further includes a filter coupled to the disk drive base. The filter includes a filter support disposed adjacent to the outer disk edge, and at least one filter element attached to the filter support disposed along the disk surface for filtering disk rotation induced airflow.

A stationary disc separator plate for use in a disc drive to suppress turbulence near a disc drive read/write head used to read data from and write data to a rotatable disc. The stationary plate is supported adjacent the disc and has substantially circular inner and outer circumferences. A leading edge and a trailing edge of the plate define an open portion to accommodate radial movement of the head adjacent the disc. A trailing edge air dam disposed at the trailing edge of the plate diverts a substantial portion of an airflow generated by rotation of the disc away from the open portion to reduce an airflow velocity at the head. In disc drives having multiple discs, a plate is preferably disposed between each pair of adjacent discs. Air vents preferably extend through the thickness of the plate to reduce aerodynamic drag and hence power consumption by the drive.
