摘要:
A storage system and method is provided including physical storage devices controlled by storage control devices constituting a storage control layer operatively coupled to the physical storage devices and hosts. The storage control layer includes a first virtual layer interfacing with the hosts, operable to represent a logical address space available to said hosts and characterized by an Internal Virtual Address Space (IVAS); a second virtual layer characterized by a Physical Virtual Address Space (PVAS), interfacing with the physical storage devices, and operable to represent an available storage space; and an allocation module operatively coupled to the first and second virtual layers and providing mapping between IVAP and PVAS. Each address in PVAS is configured to have a corresponding address in IVAS. The allocation module facilitates management of IVAS and PVAS, enabling separation of a process of deleting certain logical object into processes performing changes in IVAS and PVAS, respectively.

An optical processor is presented for applying optical processing to a light field passing through a predetermined imaging lens unit. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. The pattern is configured to define a phase coder, and a dispersion profile coder. The phase coder affects profiles of Through Focus Modulation Transfer Function (TFMTF) for different wavelength components of the light field in accordance with a predetermined profile of an extended depth of focusing to be obtained by the imaging lens unit. The dispersion profile coder is configured in accordance with the imaging lens unit and the predetermined profile of the extended depth of focusing to provide a predetermined overlapping between said TFMTF profiles within said predetermined profile of the extended depth of focusing.

A glove that enables the wearer to interact with a capacitive touchscreen without removing the glove has a first portion formed from a non-conductive knitted material and a second portion formed from an electrically conductive yarn. Exemplary is the finger tip portions of the thumb and index finger being formed from the electrically conductive yarn and the remainder of the finger tips being formed from the non conductive yarn. The second, conductive, portion may include a non-conductive yarn with an electrically conductive fiber distributed uniformly therethrough.

The is provided a storage system comprising a plurality of disk units adapted to store data at respective ranges of logical block addresses (LBAs), said addresses constituting an entire address space, and a storage control grid operatively connected to the plurality of disk units and comprising a plurality of data servers. The method of operating the storage system comprises: a) configuring a first data server to have a primary responsibility over a certain range of LBAs, b) configuring a second data server to have a secondary responsibility over said certain range of LBAs and to overtake the primary responsibility over said certain range of LBAs if the first server fails; c) responsive to a request to one or more LBAs within said certain range of LBAs, generating a primary cache object in the first data server and generating a redundancy object in the second data server; d) deleting said redundancy object upon successful permanent storing of data and/or metadata corresponding to said request, said storing provided by the first data server, e) if operation d) fails, using said redundancy object by the second server for providing permanent storing said data and/or metadata when overtaking primary responsibility, wherein said redundancy object is derivation of the primary cache object and need to be reconstructed in order to enable overtaking the responsibility.
摘要:
Methods for long-term gravimetric monitoring of carbon dioxide stored in a geological formation are disclosed. In some embodiments, the methods include the following: joining gravimetric sensors with sidewalls of boreholes in the geological formation at various vertical depths; using the gravimetric sensors, measuring a local gravitational field or a gravity gradient at a first time to develop baseline gravimetric data; reading and transmitting the baseline gravimetric data to a data recording device exterior to the boreholes; using the gravimetric sensors, measuring a local gravitational field or a gravity gradient after the first time to develop post-baseline gravimetric data; reading and; transmitting the post-baseline gravimetric data to the data recording device; and quantifying the carbon dioxide stored in the geological formation by comparing the baseline gravimetric data to the post-baseline gravimetric data to determine both vertical and horizontal positioning of the carbon dioxide stored in the geological formation.
