A duct for cooling multiple components in a processor-based device. The duct has an inlet cooling duct section for a cooling airflow focused toward a processor region. The duct also has at least one exit cooling duct section for the cooling airflow extending from the inlet cooling duct section and focused toward a component region, wherein the cooling airflow is successively transportable through the processor region followed by the component region. A processor-based system having a focused cooling duct. The focused cooling duct comprises an inlet cooling duct section for a cooling airflow having a fan receptacle, and a plurality of exit cooling duct sections for the cooling airflow extending from the inlet cooling duct section and focused toward component regions, wherein the cooling airflow is successively transportable through the inlet cooling duct section followed by the plurality of exit cooling duct sections. The processor-based system also comprises a plurality of components disposed in the component regions.

A computer enclosure has first and second removable access panels. The access panels may be locked shut by securing them both to a chassis at a single point with a locking device. When the locking device is removed, each access panel may be opened and removed independently of the other access panel. The first removable access panel has a first locking tab. The second removable access panel has a second locking tab. The first and second locking tabs do not overlap one another. When the first and second removable access panels are mounted to the chassis, the chassis restrains the first and second removable access panels from movement in first and second orthogonal directions. When the locking device is in place, the locking device restrains the first and second removable access panels from movement in a third orthogonal direction by securing the first and second locking tabs to the chassis.

A three-sided computer peripheral mounting bracket has two opposing guide rail sides and a front side but has no back side. The two opposing guide rail sides are operable to engage a computer chassis to guide the bracket during insertion and removal therefrom and to support the bracket after insertion therein. Each of the two opposing guide rail sides includes indented surfaces that are indented inward relative to outside surfaces of the guide rail sides. Each of the indented surfaces defines a recess for receiving an isolation grommet through which a computer peripheral device may be coupled to the bracket. Due to its shape, the bracket may be formed from a single piece of sheet metal. A spacer rod may be engaged between the isolation grommets to help keep the bracket square when it is not populated with the computer peripheral device. The front side of the bracket may include place holders for storing mounting screws and may include a curved handle.

An electrical connector assembly having an ejector mechanism built thereon. Left and right ejector lever mounts are fixed on left and right sides of an electrical connector. A rigid handle couples dual ejector levers pivotally engaged with the left and right ejector lever mounts. The levers actuate ejector pads for engaging a circuit board and urging the connector away from its counterpart on the circuit board. A u-shaped connector assembly may be made from two of the connector and ejector lever arrangements. A cable joins the two arrangements, and the entire assembly may be used to couple signals from a first to a second circuit board or to another component. Once the assembly is installed on the circuit boards, a u-shaped retainer bracket may be installed on top of the assembly. The retainer bracket helps to guarantee a reliable electrical connection by urging the connectors toward their counterparts on the circuit boards. The retainer bracket may be provided with clearance holes for receiving raised portions of the ejector lever handles, thereby preventing lateral motion of the retainer bracket once installed.

A transducer position sensing system, in a electromechanical drive, for determining transducer position. A sensor is mounted with a non-adjustable position and without absolute position accuracy, thereby lowering manufacturing costs. The position of the transducer at which the sensor switches states is accurately determined in a manufacturing test fixture and recorded in a permanent memory used by a drive controller. The drive controller can then accurately determine transducer position during subsequent initialization procedures.

Positioning using a position sensor and a calibrated offset between the position sensor and a reference position

The data storage cartridge drive is designed to securely accommodate and align more than one size cartridge. Reference surfaces are provided for cartridge to drive alignment in a manner so as to enhance stability, particularly during periods when the drive may experience shock or vibration. An additional reference surface is provided to supply added resistance to shock and vibration.

An alignment and latching apparatus for a drive mechanism for data tape mini-cartridges. The alignment and latching apparatus enables the drive to use a new mini-cartridge while retaining backward compatibility with older smaller mini-cartridges. The mini-cartridges have a plastic top cover and a rigid metal baseplate. For some embodiments, an alignment datum is defined by three reference points on the bottom of the mini-cartridge baseplate. In other embodiments, the alignment datum is split with two reference points on the top of the baseplate and one reference point on bottom of the baseplate. Alignment and latching forces are applied on both the plastic cover and onto the baseplate. In some embodiments, alignment force on the top cover is provided by flat springs. In alternative embodiments, alignment force on the top cover is provided by spring loaded rollers. Alignment force on the baseplate is provided by rollers or cam surfaces, pushing upward if a split datum is required and downward if a bottom surface datum is required.

A pressure transducer (10) for measuring fluid pressure in a fluid path comprising a strain gauge circuit (37) of thick film piezoresistors formed on an alumina diaphragm (36) in a Wheatstone bridge configuration. Each resistance leg of the bridge typically includes a thick film measuring piezoresistor (R1A) to which selected thick film patch-in piezoresistors (R1B, R1C, R1D, R1E) are selectively connected to create a measuring resistance network (PN1). The measuring resistance network is adjusted to a predetermined resistance value to balance and optimize the electrical symmetry of the bridge. The pressure transducer (10) includes a mechanical stop member (46) located adjacent the alumina diaphragm (36) such that the fully deflected diaphragm contacts the stop thereby physically preventing the diaphragm from deflecting an amount that would cause the diaphragm to rupture.

A fast flush catheter valve is disclosed having a valve body with a longitudinal bore therethrough for the flow of fluids through the valve. A tube is mounted substantially transverse to the longitudinal bore to substantially block the longitudinal bore. An actuating member is mounted through the exterior of the valve body so that one end of the actuating member is proximate the tube and the second end extends beyond the exterior of the valve body. A resilient biasing flange connects the second end of the actuating member to the exterior of the valve body. A capillary is mounted through the tube to provide a drip rate flow. Depressing the second end of the actuating member deforms the tube to produce a flush rate around the tube and releasing the second end causes the resilient flange to return the actuating member to a position where the tube can elastically return to the longitudinal bore blocking position. The valve is constructed from a few components and is simply and inexpensively constructed.
