Abstract: A device for metering fluid flow is disclosed. The device includes a variable sized orifice defined by a fluid flow conduit and an element movable relative to the fluid flow conduit to vary a size of the orifice, a pressure sensor configured to determine a pressure differential across the orifice and generate a pressure signal, a positioning device configured to determine a position of the element relative to the conduit and generate a position signal, and a processor configured to determine the fluid flow rate using the pressure signal and the position signal. The system can directly control the adjustable valve or orifice. Alternatively, the system can move back and forth between a direct mode and a PID mode. When in a PID mode, the system employs a standard PID algorithm with a variable gain term. The system switches to direct mode when it is advantageous for the controller to directly change the valve position based upon the setpoint, and the input and output pressures.

Abstract: In a disk drive enclosure system having carriers fitting into slots in the enclosure, each carrier has a lock mechanism. The lock mechanism has a part which rotates between locked and unlocked positions, and the part has a feature that blocks removal of the carrier when the part is in the locked position, while permitting removal of the carrier when the part is in the unlocked position. The part is plastic and is molded of a clear material serving as a light pipe. A light source is behind the part, so that the ability of light to pass through the part is affected by the locked/unlocked position of the part. The part has a shape feature that assists a user in distinguishing between locked and unlocked positions, and the light indicator further assists the user in this way. Valuable bezel space is saved, especially in comparison with some prior-art locking mechanisms.

The rivet is embedded in the two parts, and the parts flow radially against the concave body of the rivet. No drilling is required, and the parts are held in carefully defined position while being joined, so that the assembled enclosure satisfies strict dimensional tolerances.
