Abstract: Access to secured items in a computing system is requested instead of being persistent. Access requests may be granted on a just-in-time basis. Anomalous access requests are detected using machine learning models based on historic patterns. Models utilizing conditional probability or collaborative filtering also facilitate the creation of human-understandable explanations of threat assessments. Individual machine learning models are based on historic data of users, peers, cohorts, services, or resources. Models may be weighted, and then aggregated in a subsystem to produce an access request risk score. Scoring principles and conditions utilized in the scoring subsystem may include probabilities, distribution entropies, and data item counts. A feedback loop allows incremental refinement of the subsystem. Anomalous requests that would be automatically approved under a policy may instead face human review, and low threat requests that would have been delayed by human review may instead be approved automatically.

The left handle and the right handle are identical.

Abstract: A computing device receives a setup command and signals mobile robots to move sensor targets into positions within a predetermined range of a turntable. Each mobile robot may be coupled to a sensor target. Once the sensor targets are moved into the positions, calibration may be initiated, in which a vehicle is rotated using the turntable, and sensors coupled to the vehicle are calibrated based on detection of the sensor targets.

Abstract: A malfunction insert is for a firearm that includes a magazine. The malfunction insert includes a narrow end comprising a narrow edge, a concave surface disposed at an opposite end of the malfunction insert from the narrow end, and a central member that connects the concave surface and the narrow end. The malfunction insert is configured to be inserted into the magazine.

Abstract: A vehicle rear window cover comprising: a cover portion; a first strap assembly, which comprises one or more strap loops; a second strap assembly, which comprises one or more strap loop; two hooks that are configured to engage with said strap assemblies and a vehicle, such that the cover portion substantially covers the rear window of a vehicle. Because the hooks may be moved from loop to loop, the cover is adjustable. The cover may also comprise support members that prevent bulging, flapping, or puckering of the cover portion.

Abstract: Methods and systems pertaining to generating a startup or other operating order of pumps of a pumping system for performing a subterranean formation fracturing operation, and/or another pumping operation, and for coordinating distribution of flow rates to the pumps for performing the pumping operation.

Abstract: Systems and methods for sensing an amount of a liquid in a container are provided. A conduit is provided that has a length positioned relative to a portion of the container where a level of the liquid in the container changes when liquid is added to the container or liquid is removed from the container. The conduit is in fluid communication with the container to therefore allow an amount of the liquid to enter the conduit that is proportional to the amount of the liquid in the container. An outlet is provided along with a valve. The valve is in fluid communication with the conduit and the outlet, where the valve is selectable to allow the amount of liquid in the conduit to pass to the outlet, the amount of liquid passing to the outlet proportional to the amount of liquid in the container.

Abstract: A forward brace assembly for a firearm includes a forward portion designed to interface with an operator's off hand and an aft panel extending rearward from the forward portion. At least a portion of the forward brace assembly is attached to an underside of a handguard of the firearm. The aft panel prevents the operator's off hand from wrapping around a rear side of the forward portion.

Abstract: A firearm receiver assembly includes a receiver body, a threaded mount at a rear portion of the receiver body, a magazine release assembly including a magazine release portion on at least one side of the receiver body, a bolt release assembly including a bolt release central portion and a bolt release portion on at least one side of the receiver body, and a safety selector assembly including a safety portion on at least one side of the receiver body. The bolt release central portion translates vertically within a cavity of the receiver body.

Abstract: Systems and methods for tracking and searching the usage, flow or communication of assets are disclosed. Embodiments as disclosed herein may create and update a graph representing the assets in an enterprise, where the objects and relationships in the graph represent the assets, communications, users or relationship. The graph may be queried to discover a wide variety of information regarding these assets, communications, users or relationships.

Abstract: An indoor tent that is configured to encompass a couch while maximizing viewing angles from inside the tent.

Abstract: An operating system for a firearm includes a forward bolt includes a forward bolt cavity, a carrier disposed on a rear side of the forward bolt, the carrier including a carrier cavity, a short cam pin including (i) a forward section that is at least partially disposed within the forward bolt cavity and (ii) a rear section that is at least partially disposed within the carrier cavity, a plurality of bearings that interface with the forward bolt, a retracted configuration where the short cam pin is in a rear position relative to the forward bolt, and a deployed configuration where the short cam pin is in a forward position relative to the forward bolt.

Abstract: A firearm operating system includes a housing, a central pivoting member disposed within the housing, a trigger including a portion disposed within the housing and a portion extending outside the housing such that the portion of the trigger within the housing includes a hole and at least one finger that extends in a first direction from the hole. Due to movement of the trigger, the at least one finger presses against the central pivoting member to cause the central pivoting member to rotate.

Abstract: A system for determining an energy requirement of a vehicle for a journey. The system may comprise a predictor mechanism to predict, using an energy prediction algorithm, a vehicle energy requirement for the journey. The system comprises an updater mechanism configured to refine the energy prediction algorithm for the vehicle by determining for each of a number of historical journeys undertaken by the vehicle, an error between an actual vehicle energy usage for the historical journey and a predicted energy usage derived using the energy prediction algorithm for the historical journey. An aggregate error is calculated from the errors of the number of historical journeys. The updater is arranged to adjust the energy prediction algorithm to reduce the aggregate error.

Abstract: A method for monitoring data integrity on a network includes reading error data from an interface associated with a particular link of the network in response to error data being present in a message received on the particular link. The method also includes creating a report message including the error data and transmitting the report message to a network monitoring algorithm operable on a processor circuit. The network monitoring algorithm is configured to determine a data integrity of the particular link based on the error data.
