Abstract: A network system includes first nodes and a second node. Each first node is directly communicatively connected to the second node, or each first node is indirectly communicatively connected to the second node through another first node. The second node includes a network layer and an application layer. When a new node desires is joining the first nodes, the network layer sends an update signal including first network address information of the new node. The application layer is configured to connect to a database and perform an authentication on the first network address information of the new node based on a node list in the database. When the new node passes the authentication, the application layer stores the update signal in the database.

Abstract: A data deduplication method is executed by a controller for a solid state drive (SSD). The controller receives a signature for a block of data. The controller performs a comparison of the signature and information in a signature library and determines whether or not the signature matches the information. The controller sends a signal that indicates a result of the comparison. If the signature and the information match then the signal has a first value indicating that the block of data is already stored on the SSD; if the signature and the information do not match then the signal has a second value that is different than the first value.

Abstract: Embodiments of the present invention use a NAND block as the basic write operation unit and ensure that the write operation uses the same basic unit as the erase operation. In this way, the flash product maintains the same level of granularity for read and write operations. The mapping between logical block addressing (LBA) and physical block addressing (PBA) are at the page level. Wear leveling and garbage collection are simplified so the robustness and performance is enhanced. If the data is frequently written, there are no concerns regarding data retention. Embodiments of the present invention evenly distribute hot data using a global optimization perspective based on this observation. When dealing with hot data, the NAND flash's required data retention capability may be adjusted to increase P/E cycles.

Abstract: A computer implemented process is described for testing multiple electronic devices under test (DUTs). A design test pattern or command/instruction is generated with an electronic design automation tool (EDA). The generated design test pattern and command/instruction is sent directly to an automated test equipment apparatus (ATE) over a UNIX or scripting language based, and/or a network based, communication pipeline. The ATE converts the sent design test pattern to an instance of the test pattern directly executable by the ATE. The ATE apparatus inputs test signals to each of the multiple electronic DUTs based on the executable test pattern. The ATE apparatus then receives, from each of the multiple electronic DUTs, a test result based on the input test signals. The ATE returns the received test result, and a report of an action responsive to the command/instruction to the EDA tool, which may then process the test results and report.

Abstract: A method of accessing data stored in a storage disk of a storage system includes the steps of receiving a read operation to a sector of the storage disk and in response to an error returned from the read operation, determining whether the sector is to be replaced. If the sector is determined to be replaced, the method further includes replacing the sector with a spare sector. The data previously stored at the replaced disk sector are reconstructed and written to the spare sector, and the LBA assigned to the replaced sector is reassigned to the PBA associated with the spare sector.

Abstract: A machine provides a user with repeating messages that reference a purchasable product. The time interval to be inserted between the messages is modified dynamically by the machine, based on a popularity score of the purchasable product, as determined by the machine. The machine accesses social media servers and obtains counts of communications that reference the purchasable product. The machine accesses threshold values that each correspond to a different social media server and its application programming interface (API). By comparing the counts of communications to their corresponding threshold values, the machine determines which counts transgressed their threshold values and calculates a popularity score of the purchasable product based on those counts. Based on the calculated popularity score transgressing a reference popularity score, the machine modifies the time interval that will be inserted between the messages that reference the purchasable product.

Abstract: System and method of storing data into a cloud system with high data consistency. The cloud system utilizes a non-volatile buffer at an entrance stage server to buffer incoming data as received. The data traverses from the entrance stage through various transaction stages in a data path until it is written to a destination storage device of the cloud system. Data is transmitted across stages in a pipelined manner according to an event-based schedule. A respective stage is capable of receiving a data unit from the last stage, caching and/or processing the data unit, verifying data consistency, and sending to the next stage. If a data error is detected in the data path, the identified data unit is recovered from non-volatile buffer, inserted in the data stream and resent over the data path.

Abstract: An auto tools change with space allowance for tool rejection of spindle includes an arm seat, an arm shaft, a tools change arm, a flat cam, and a driving arm, while the flat cam has a driving groove for driving the driving arm to swing and thus facilitates the tool clamping and tool unclamping. Therein, the driving arm has a tool clamping section having an allowance groove, a first transition section, a tool unclamping section, and a second transition section. Therefore, a larger width of the allowance groove is provided on the driving groove, thereby offering a sliding space for the tools change arm. Thus, a space allowance is produced during tool pushing process, thereby not only preventing the main shaft and the tool from being damaged, but also preventing the tools change arm from deformation.
