摘要:
A method and apparatus for obtaining an image to determine a three dimensional shape of a stationary or moving object using a bi dimensional coded light pattern having a plurality of distinct identifiable feature types. The coded light pattern is projected on the object such that each of the identifiable feature types appears at most once on predefined sections of distinguishable epipolar lines. An image of the object is captured and the reflected feature types are extracted along with their location on known epipolar lines in the captured image. Displacements of the reflected feature types along their epipolar lines from reference coordinates thereupon determine corresponding three dimensional coordinates in space and thus a 3D mapping or model of the shape of the object at any point in time.

A storage system, including: (a) a primary storage entity utilized for storing a data-set of the storage system; (b) a secondary storage entity utilized for backing-up the data within the primary storage entity; (c) a flushing management module adapted to identify within the primary storage entity two groups of dirty data blocks, each group is comprised of dirty data blocks which are arranged within the secondary storage entity in a successive sequence, and to further identify within the primary storage entity a further group of backed-up data blocks which are arranged within the secondary storage entity in a successive sequence intermediately in-between the two identified groups of dirty data blocks; and (d) said flushing management module is adapted to combine the group of backed-up data blocks together with the two identified groups of dirty data blocks to form a successive extended flush sequence and to destage it to the secondary storage entity.

A method for initializing a memory area, the method includes: receiving a request to access a first memory sub area of a first memory area that comprises multiple memory sub areas; and initializing the first memory sub area if a first memory area initialization indicator differs from a first memory sub area initialization request indicator; wherein the first memory area initialization request indicator is a multiple bit variable indicative of a time of a last request to initialize the first memory area and the first memory sub area initialization indicator is a multiple bit variable indicative of a time of a request to initialize the first memory area that resulted in a last initialization of the first memory sub area.
摘要:
A method of implementing a logical unit reset across a plurality of interfaces in a distributed storage system, comprising: initiating a session for implementing the logical unit reset across the plurality of interfaces in response to receiving at a central controller a logical unit reset command from an originator interface, and writing session-data including an indication that the originator interface implemented the respective logical unit reset locally; communicating a logical unit reset command from the central controller to each interface other than the originator interface; updating the session data in response to receiving an indication from an interface that the logical unit was successfully reset locally and when each one of the plurality of interfaces implemented the logical unit reset locally, communicating a success response to each one of the plurality of interfaces.

A system, apparatus and method of performing 3-D object profile inter-planar estimation and/or range inter-planar estimation of objects within a scene, including: providing a predefined finite set of distinct types of features, resulting in feature types, each feature type being distinguishable according to a unique bi-dimensional formation; providing a coded light pattern having multiple appearances of the feature types; projecting the coded light pattern, having axially varying intensity, on objects within a scene, the scene having at least two planes, resulting in a first plane and a second plane; capturing a 2-D image of the objects having the projected coded light pattern projected thereupon, resulting in a captured 2-D image, the captured 2-D image including reflected feature types; determining intensity values of the 2-D captured image; and performing 3-D object profile inter-planar estimation and/or range inter-planar estimation of objects within the scene based on determined intensity values.

摘要:
A method for of accelerating database log hardening using specific per block data protection and damage control is provided. A per write specification is implemented to determine when database log data is mirrored synchronously or asynchronously. Synchronous minoring is performed upon reaching a predetermined threshold, based on one or more parameters such as transaction value, both individual and cumulative, and the quantity of data written since the last synchronous minoring. As data is added to the database log, it is written specifying asynchronous minoring to the primary log file. Once a threshold is met, a write specifying synchronous minoring is performed to both the primary and secondary log files, thereby hardening the log file in both primary and secondary storage subsystem.
