International Classification:

G11B 554

US Classification:

360105

Abstract:

A system for loading a transducing head ( ) to a flying elevation proximate a rotating surface of a disc ( ) is disclosed. The system includes a piezoelectric device ( ) that is selectively expanded and contracted to control a height of the head ( ) on a flexure spring ( ) from the surface of the disc ( ). The system preferably includes control circuitry ( ) for generating electrical control signals to manage the expansion and contraction of the piezoelectric device ( ) according to operating characteristics of the disc ( ).

International Classification:

G11B005/596

US Classification:

360/078050

Abstract:

A dual-stage disc drive actuation system for positioning a transducing head over a selected track of a rotatable disc having a plurality of concentric tracks includes a low resolution actuator and a high resolution microactuator. An input circuit provides a signal corresponding to the selected track. The actuator and microactuator are then operated to position the head over the selected track. The dual-stage actuation system positions the head over the selected track without significant off-track error within about 0.5 milliseconds for a track density of at least about 12,000 tracks-per-inch.

US Classification:

280 4718, 280 4724

Abstract:

A single handled two-wheeled gimbaled bucket dolly or hand truck is configured to lift, transport and pour the contents of a bucket or container with minimal operator effort. This dolly may use a horizontal “C” shaped frame cross member and two rigid vertical gimbaled columns to support a pivoting bucket or a modular tray or basket. This apparatus allows the bucket to be tilted a 180 degrees on its horizontal axis and to effortlessly dispense its contents and to transport the bucket or tray across uneven terrain.

A61M 16/20

US Classification:

12820421

Abstract:

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.
