Abstract: Techniques control a utility vehicle. Such techniques involve storing electric power in a lithium battery of the utility vehicle. Such techniques further involve operating a motor controller of the utility vehicle in a normal mode in which the motor controller provides electric power from a lithium battery of the utility vehicle to an electric motor of the utility vehicle to turn one or more ground engaging members of the utility vehicle. Such techniques further involve, after operating the motor controller in the normal operating mode, operating the motor controller in a walkaway mode in which the motor controller configures the electric motor to provide braking torque.

Abstract: Techniques involve controlling battery access on a utility vehicle. Such techniques involve monitoring status of input signals from a group comprising: a lithium battery system, a keyed switch, and a charging receptacle, comparing the status of the input signals to timeout settings stored in memory of the motion control system, initiating a timer based on comparison of the input signals to the timeout settings, and disconnecting at least one direct current (DC) path between a lithium battery interface and a power distribution interface of the utility vehicle in response to expiration of the timer. Such techniques further involve, after disconnecting, reconnecting the at least one DC current path between the lithium battery interface and the power distribution interface in response to a change in status of at least one of the input signals. Such techniques may be performed by a motion control system of the utility vehicle.

Abstract: A control system for handling a fault condition on a utility vehicle includes a lithium battery, a contactor configured to control electrical access to the lithium battery, and control circuitry coupled with the lithium battery and the contactor. The control circuitry is configured to detect, while the contactor is closed to provide a set of loads of the utility vehicle with electrical access to the lithium battery, onset of a fault condition. The control circuitry is further configured to perform, in response to detection of the onset of the fault condition, a set of remedial operations to address the fault condition. The control circuitry is further configured to perform, after a predefined amount of time has elapsed since the onset of the fault condition, a subsequent operation which opens the contactor if the fault condition remains and maintains closure of the contactor if the fault condition does not remain.

Abstract: Methods, systems, and media for supporting snapshots and clones in a scale out storage system are disclosed. The system maintains first metadata that maps logical addresses of logical data blocks to corresponding content IDs, a distributed hash table that maps content IDs to corresponding node IDs, and second metadata that maps content IDs to corresponding physical addresses of physical data blocks. Clones are created by mapping each logical block address of each clone to the content ID associated with its corresponding logical block address of the original and incrementing the reference counts in the second metadata. The task of incrementing reference counts in the second metadata can be distributed across multiple storage nodes. A logical device can be designated as a golden image. Clones of a golden image are created by decrementing its clone credit without incrementing the reference counts in the second metadata.

Abstract: Methods, apparatuses, systems, and media for implementing a persistent read cache in a scale out storage system are disclosed to reduce access latency and achieve higher performance. Both the cached data blocks and distributed data placements are referenced by their unique content identifiers and are deduplicated. The persistent read cache spans across node reboots and is inherently coherent across all storage nodes without a distributed lock manager. The cached data blocks share the same storage pool as distributed data placements without costing storage capacity. A cached data block can become a distributed data placement or vice versa without moving the physical data block. Methods are also disclosed to reduce time to performance for logical device mobility.

Abstract: A compliance user or auditor is enabled to inject failures into a sandbox environment, which may be similar to a production service. The sandbox environment may be monitored by the same automation that watches compliance controls in the production service. As the user injects compliance failures into the sandbox, they may detect the appropriate alerts fire in the monitoring system, thereby gaining trust that the monitoring works as it should. A rich report resulting from the test activities may allow the user or auditor to see how a failure of a compliance control leads to the expected monitoring alert.
