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.

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 computer readable media for backing up and restore a deployment on a cloud computing platform are described. A deployment on a cloud computing platform includes a set of virtual machines and corresponding disks. A deployment may include multiple subunits designated as deployment jobs. A respective job specification file specifies respective resources used by each deployment job. The resources include various scripts specifying actions to take before, during, and after a backup. A backup orchestrator, upon receiving a backup request for the deployment, executes the scripts in a pre-specified sequence ordered by script type. When a particular type of scripts executes, the corresponding script for each deployment job, if specified in the specification file to correspond to that type, executes. When all scripts of a particular type finish execution, scripts having a next type execute. Accordingly, the operations of backing up multiple deployment jobs are synchronized and orchestrated.

Abstract: A technique controls charge on a lithium battery of a utility vehicle. The technique involves operating electronic circuitry of the utility vehicle in a normal operating mode in which the electronic circuitry charges the lithium battery to a normal charge level. The technique further involves, after operating the electronic circuity in the normal operating mode, transitioning the electronic circuitry from the normal operating mode to a storage mode in which the electronic circuitry is configured to set an amount of charge on the lithium battery to within a predefined storage range (or level) which is lower than the normal charge level. The technique further involves, in response to transitioning the electronic circuitry, adjusting the amount of charge on the lithium battery from an initial charge level which is outside the predefined storage range to an adjusted charge level which is within the predefined storage range.
