Data Retrieval System that Provides Retrieval of Data to Any Point in Time

INVENTOR • Ken Qing Yang

ABSTRACT

This new disk array architecture is capable of providing timely recovery to any point-in-time for user data stored in the array, referred to as TRAP (Timely Recovery Any Point) array. This new architecture has little negative impact on application performance while providing continuous data protection capability, additional security and reducing storage space requirements.

APPLICATION

•Data retrieval for record keeping purposes such as in distributed electronic healthcare information systems (EHS), electronic news information record keeping systems, and Internet information record keeping systems.
•Data recovery due to information system failures.

FEATURES & BENEFITS

This system reduces the amount of data to be stored and transferred in a networked storage system.
It includes a disk array architecture that provides timely recovery to any point-in-time, referred to as TRAP-Array (Timely Recovery Any Point). TRAP recovers data to any point-in-time very quickly upon failure and also uses less storage space than traditional daily differential backup/snapshots.
Architecture: TRAP-Array opens up another dimension for storage arrays. It is orthogonal and complementary to RAID (Redundant Array of Independent disks) in the sense that RAID protects data in the dimension along an array of physical disks while TRAP protects data in the dimension along the time sequence.
With a direct and fast encoding scheme, the TRAP architecture presents dramatic space savings because of content locality that exists in real world applications. Furthermore, it provides faster data recovery to any-point-in-time than traditional techniques because of the drastically smaller amount of storage space used.
The implementation is file system and application independent. Any file system or database application may readily run on top of a system of the invention. The software prototype is a block level device driver. The driver takes write requests from a file system or database system at block level, then the system performs normal write into the local primary storage and at the same time performs parity computation.
The storage architecture includes a plurality of data storage mediums, an encoder system and a time stamp circuit. The plurality of data storage mediums each include a parity bit that provides an indication of the parity of the data in each respective data storage medium.

ABSTRACT

A method is disclosed for recovering data associated with a damaged file stored in a NAND gate array memory. The method includes the steps of: identifying all meta data associated with the damaged file; identifying each logical block address of all identified metadata; collecting all physical block addresses associated with one of the identified logical block addresses or the identified meta data; counting in a replace table (ReplTable) a number of matches to a physical block address of the damaged file for each physical block address of the damaged file; choosing a block in a linked list that corresponds to the physical block address of the block in the linked list; and linking all chosen blocks to form a replicated file.

APPLICATION

This can be used to recover information from a damaged flash memory such as a mobile phone or usb-drives, mainly for forensic purposes.

FEATURES AND BENEFITS

Would be great for law enforcement and other forensic accounting applications.

Selective Surface Smoothing Using Lasers

INVENTOR • Manbir Sodhi

ABSTRACT

The technology is a micro melting process to melt surface irregularities or features on a surface of a substrate. The method includes providing a laser and a control mechanism associated with the laser. The control mechanism varies the laser intensity and direction by varying and monitoring the power of the laser while simultaneously considering multiple key factors.

APPLICATION

Allows realization of the potential of solid free-form fabrication (SFF) technology for rapid production of tools and dies and for re-manufacturing valuable components. Lowers the cost and time of expensive post-processing due to issues of surface improvement in solid free-form fabrication (SFF), widely used for prototyping in additive manufacturing. SFF techniques generate surfaces with roughness compared to rough machining operations, and generally requires post-processing to bring to specification. The surface roughness specifications can be achieved during the metal deposition operations, expensive and time consuming re-fixturing and finish machining operations can be eliminated, creating large cost and time savings.

FEATURES & BENEFITS

The surface roughness specifications can be achieved during the metal deposition operations, expensive and time consuming re-fixturing and finish machining operations can be eliminated, creating large cost and time savings.
Micro-melting is applicable to a wide variety of materials, creates little to no damage to the base metal and allows precise control. Material systems may include but are not limited to glass, polymers, ceramics, diamonds, and metals.
The invention improves surface quality by a combination of planned laser micro-melting/ablation and workpiece motion. The micro-melting process can simultaneously consider all the following factors, and use them in all desired combinations:
a) the nature of the irregularities being considered;
b) the material of the substrate;
c) the power of the laser;
d) the approach direction and angle of the laser; and
e) the melting run-off, i.e. the local melting of peaks to flow into the valleys
Selective Surface Smoothing Using Lasers
The information from different substrates is saved in a database and then prior knowledge and computer data can be used to control the
laser to remove the irregularities in the surface of the substrate.
