The present invention is directed toward the resumption of a journaling process in a data management appliance after a period of unavailability. The data management appliance is a random-access storage system that at the logical block level replicates the contents of a primary storage system over time. A small “dirty extent map” is established on the primary storage device. The dirty extent map keeps track of which portions of primary storage are written to while journaling is interrupted. When journaling is resumed, the contents of the dirty extents are compared to the latest replica of the primary storage to identify the differences. These differences are then journaled as if they were write commands. Meanwhile, new write commands are also journaled by the data management appliance. Once the differences of all of the dirty extents have been journaled, the data management appliance may resume normal journaling operation.

The perception of a displayed image is altered for viewers moving relative to the position of the display system screen, thereby imparting a sense of three-dimensional immersion in the scene being displayed. A display generator generates a scene having foreground and background elements, and a display screen displaying the scene. A sensor detects the position of a viewer relative to the display screen, and a processor is operative to shift the relative position of the foreground and background elements in the displayed scene as a function of viewer position, such that the viewer's perspective of the scene changes as the viewer moves relative to the display screen. The foreground and background elements may be presented in the form of multiple superimposed graphics planes, and/or a camera may be used to record the scene through panning at sequential angles. The system may be used to implement virtual windows, virtual mirrors and other effects without requiring viewers or users to modify behavior or wear glasses, beacons, etc.

A prosthetic limb has an outer surface that is a mirror image of an intact limb or a generic limb design. The intact limb is scanned and the surface data is manipulated to create a virtual mirror image. If generic data is used, the intact leg can be measured and the generic surface can be adjusted so the prosthetic limb appears similar to the intact limb.

The design data for the virtual prosthetic limb is forwarded to a rapid prototyping machine that fabricates the entire leg simultaneously. Once completed, the prosthetic limb is shipped to the patient.
