Abstract: A hard disk drive assembly having a hard disk drive positioned within an external housing. Isolators formed of a resilient material, such as an elastomeric material, are interposed between the hard disk drive and an external housing. The isolators also preferably having a plurality of openings that extend there through that lower the stiffness of the isolators during small deflections such as those caused by vibrations, but large deflections, such as those caused by shocks cause the openings or holes to close there by generating greater stiffness is response to external shocks.

Abstract: A testing apparatus, for subjecting a device-under-test to oscillating acceleration, includes a stage having a mounting surface attachable to the device-under-test. An actuator is coupled to the stage, and also coupled to a reaction mass movable along a linear axis. A first flexure plate has a first flexure plate middle and a first flexure plate periphery, with the first flexure plate middle attached to the stage at a first stage end. A second flexure plate has a second flexure plate middle and a second flexure plate periphery, with the second flexure plate middle attached to the stage at a second stage end that opposes the first stage end. The first flexure plate periphery and the second flexure plate periphery are attached to the frame. The first and second flexure plates define major surfaces that are substantially perpendicular to the linear axis.

Abstract: A liquid dispensing apparatus for dispensing droplets of a liquid, and methods for measuring various fluid parameters of the liquid are described. The liquid dispensing apparatus comprises a container having a chamber for holding a liquid. An orifice is positioned at an end of the chamber for dispensing droplets of the liquid, the orifice being configured to retain the liquid in the container if the container is positioned with the orifice facing in a downward direction. An acoustic transducer means is at least partially positioned in the chamber for periodically propagating a focused acoustic beam toward the orifice and through at least some of the liquid while the liquid is contained in the chamber, with the focused acoustic beam being capable of causing a droplet of the liquid to be ejected from the orifice when a free surface of the liquid is within the depth of field of the acoustic transducer means.

Abstract: A customer document management system, which includes customer information store on a mainframe computer, said customer information being updateable from multiple sources. A data consolidator operates on the customer information to compile customer documents, including data reconfiguration into a customer document output database and multiple format output devices driven from the customer document output database.
