Abstract: Reversible gerotor pump system comprising a cylindrical housing with a 180° slot, an eccentric ring with a locking pin fixed thereto and movably engaged in the slot; an outer rotor and inner rotor with meshed teeth, and shaft for driving inner rotor and system. The eccentric ring has convex profile on the outer diameter. A positive contact system, which can be a spring-and-plunger system or frictional disc brake system is provided to increases frictional force between the eccentric ring and the outer rotor. The locking pin moves in the slot with clearance at both rotation directions to provide a self-damping effect. The suction port has prolongations at both upstream and the downstream sides to increase filling time such that the pump can have a fill speed of above 5000 rpm, and the volumetric efficiency is at least 90% at 5000 rpm.

Abstract: A system and method for performing a failure analysis on a computing system uses a Bayesian network that is generated from a correlation directed acyclic graph (CDAG) of nodes that represent entities in the computing system with edge weights for edges between the nodes. The CDAG is generated using log entries of the computing system with reference to a dictionary file, which specifies entity types, dependency types of the entity types, expressions that return values representing prior probabilities of failure for the dependency types, and the edge weights for the dependency types. The Bayesian network generated from the CDAG includes conditional probabilities for edges of the Bayesian network based on the edge weights of the CDAG. The Bayesian network is used to compute posterior probabilities of possible causes of a new failure event in the computing system and output at least one probable cause with an associated posterior probability for the new failure event.

Abstract: A method for improving data transmission security at a user equipment comprises receiving, from a source network node, a connection release message including instructions for computing a hash value for data to be included in a connection request message; computing the hash value based on the instructions included in the connection release message; calculating a token based on the hash value, and sending, to a target network node, the connection request message including the token. The method may further forward the data from the target network node directly to a gateway after the token has been verified. The method may reduce a signaling overhead by having a fixed-size hash value for data. Furthermore, the method may improve a transmission security by including the token in an RRC message, in which the token is calculated based on the hash value representing the data.

Abstract: A processing device, operatively coupled with a memory device, is configured to perform a write operation on a page of a plurality of pages of a data unit of a memory device, to store host data in the page of the data unit. The processing device further generates a parity page for the host data stored in the page of the data unit and adds the parity page to parity data stored at a parity data storage location. Responsive to determining that a first size of the stored parity data satisfies a first condition, the processing device initiates execution of a compression algorithm to compress the stored parity data. Responsive to determining that a second size of the parity data resulting from the execution of the compression algorithm satisfies a second condition, the processing device performs a scan operation to release at least a subset of the stored parity data.

Abstract: A method is performed by a node configured to implement an Operation, Administration, and Maintenance (OAM) protocol for rapid link failure detection. The node receives peer OAM packets sent by a peer node over a link at a peer periodic interval. While in a first mode of the OAM protocol, the node determines whether the peer node is reachable based on the peer OAM packets, sends OAM packets to the peer node at a periodic interval to indicate to the peer node that the node is reachable, and responsive to detecting a critical condition of the node that impairs the sending the OAM packets, transitions to a second mode of the OAM protocol. While in the second mode, the node adds, to the peer OAM packets, a code to indicate the critical condition, and reflects the peer OAM packets with the code back to the peer node.

Abstract: A policy engine validates one or more security tokens in an authenticated request using a sequence of partial policy validations. Multiple policies may be applied to the security token using the work product generated from each failed policy. The policy that succeeds in validating the security token has a portion of its work performed through previously-failed policies that did not complete successfully. In this manner, the validation of a policy is performed faster and more efficiently since the previous processing is not repeated whenever a new policy is applied.

Abstract: Methods and apparatus consistent with the invention provide the ability to organize, index, search, and present time series data based on searches. Time series data are sequences of time stamped records occurring in one or more usually continuous streams, representing some type of activity. In one embodiment, time series data is stored as discrete events time stamps. A search is received and relevant event information is retrieved based in whole or in part on the time stamp, a keyword indexing mechanism, or statistical indices calculated at the time of the search.

Abstract: An anomaly detection and analysis system detects anomalies in time series data from key performance indicators (KPIs). The system decomposes samples of the time series data received during a first time interval into a trend component, a seasonality component, and a randomness component. The system identifies an upper bound and a lower bound based on the trend component, the seasonality component, and a variance of the randomness component. The system reports a sample received after the first time interval as an anomaly when the sample exceeds the upper bound or the lower bound. The system recalculates the trend component, the seasonality component, and the randomness component when more than a threshold percentage of the samples of the time series data received during a second time interval are reported as being anomalous.

For example, a method comprises managing generation of a backup copy of data in each of a set of storage arrays in an active-active storage configuration by causing one or more host devices that access the set of storage arrays to synchronously halt input-output operations associated with the set of storage arrays prior to causing the backup copy to be created in each of the set of storage arrays.

The method includes, until a threshold number of computing devices have been added to the search party: identifying one or more candidate second computing devices for addition to the search party, each candidate second computing device satisfying criteria for inclusion in the search party; adding one or more of the candidate second computing devices to the search party in response to receiving an acceptance of a request sent to the candidate second computing devices to join the search party; determining that a number of second computing devices added to the search party fails to satisfy the threshold number of computing devices; and modifying the criteria for inclusion in the search party.

Abstract: A machine learning (ML) module that analyzes multiple language-influencing factors to correct textual content in a more meaningful and efficient manner. In the context of product support, the ML module considers the factors such as a customer's persona that shapes the words a customer chooses while speaking/writing to a customer support agent, current social trends that create new words in the social media/social platforms related to the customer's support issue, and the device used by the customer to input the textual content because different words may be input by the customer when using a smart phone versus a desktop/laptop personal computer with a traditional keyboard. The ML module also may analyze the agent's persona to modify agent's response to the customer because the agent's persona can influence the content of the agent's text. The ML module automatically corrects textual content in real-time before it is sent to the relevant recipient.
