US Patent:

6938123, Aug 30, 2005

Filed:

Jul 19, 2002

Appl. No.:

10/198863

Inventors:

Kenneth Willis - Castle Rock CO, US
Stephen S. Selkirk - Broomfield CO, US

Assignee:

Storage Technology Corporation - Louisville CO

International Classification:

G06F012/00

US Classification:

711114, 714 6

Abstract:

In a redundant storage subsystem including an array controller and a group composed of a plurality of storage devices, a method is provided. The method includes logically parsing each storage device of the group into a corresponding number of allocation units. A stripe size is selected, and a series of writing operations is performed. Each writing operation includes selecting a subset of the plurality of storage devices based on the stripe size, and writing the stripe of data to the subset of the plurality of storage devices. The selected subset over the series of writing operations varies from operation to operation.

US Classification:

Abstract:

A set back weight is moved by inertial force from a first position to a second position during acceleration of a missile. The set back weight is biased toward its first position to preclude its movement to its second position until the missile undergoes the rate of acceleration which is normally associated with a successful launch of the missile. Upon reaching the second position the weight becomes connected to a piston disposed in a fluid containing reservoir so that when the missile undergoes a reduction in its rate of acceleration and the set back weight moves toward its first position that movement is transmitted to the piston to express fluid from the reservoir. Fluid from the reservoir flows into a working cylinder to move an arming piston therein. Movement of the arming piston is slowed to delay arming of the missile by a flow restricting orifice in the path of fluid flow from the reservoir to the working cylinder.

International Classification:

US Classification:

Abstract:

A system for supporting and deploying a rocket motor nozzle extension that is stowed in concentric overlapping relationship with the nozzle. The system includes a plurality of articulated frames having first and second pairs of links pivotally connected, respectively, to the nozzle and to the nozzle extension. Articulation for each frame is provided by a knee hinge connecting the two pairs of links at their outer ends, thereby permitting the pairs of links to swing apart. A retractable cable looped around the knee hinges of each of the frames is capable of forcing the hinges inwardly toward the nozzle and nozzle extension to force the pairs of links of each frame apart and to move the nozzle extension to a deployed position at the end of the nozzle. Retraction of the cable is accomplished by a motor driven spool on which the cable is wound. Shearable locking pins in the knee hinges of the frames lock the system to hold the nozzle extension in its stowed position until the system is activated to deploy the extension.
