Abstract: Breaches of service level agreements (SLAs) of a computer network can be identified based on changes to statuses of components of the computer network. A status of a component of the computer network can be determined to have changed responsive to an event affecting the computer network.

Records of the task table are associated with ones of the SLAs. It can then be determined that the changed status of the component prevents a condition of an SLA associated with the updated record from being met. The SLA can be identified as breached responsive to that determination.

Abstract: A virtualized peripheral driver and filter are installed at a kernel level of an Operating System (OS) on a host device. A new peripheral driver is installed on the host device and added to the peripheral device stack within the OS. Events generated from the user level of the OS are pushed through the stack for processing by a newly attached peripheral of the host device using the new peripheral driver. Events produced from the kernel for the peripheral are trapped by the filter when passing up through the stack to the user level of the OS and provided to the virtualized peripheral driver. The virtualized peripheral driver repackages, translates, and formats the events produced from the kernel as OS events expected by the OS for processing and the repacked, translated, and formatted events are processed by the OS.

Abstract: In one embodiment, systems and methods are disclosed for evaluating autonomous driving vehicle (ADV) driving decisions. A driving scenario is selected, such as a route or destination or type of driving condition. ADV planning and control modules are turned off and do not control the ADV. As a user drives the ADV, sensors detect and periodically log a plurality of objects external to the ADV. Driving control inputs of the human driver are also logged periodically. An ADV driving decision module generates driving decisions with respect to each object detected by the sensors. The ADV driving decisions are logged, but are not used to control the ADV. An ADV driving decision is identified in the logs, and a corresponding human driving decision is extracted, graded, and compared to the ADV driving decision. The ADV driving decision can be graded using the logs and graded human driving decision.

Abstract: The collection and aggregation of time series data from a variety of heterogenic time series data sources. This may be accomplished through the use of multiple collector modules, each configured to gather time series data from a different time series data source, and translate that time series data from its original format into a common format.

Accordingly, the principles describe herein allow real world information to be gather and acted upon even when the time series data is gathered from disparate sources. Furthermore, different systems can rely upon the actions being consistent based on access to the same underlying data.

Abstract: An integrated circuit design may include registers and combinational logic. The registers may be reset using an original reset sequence. Integrated circuit design computing equipment may perform register moves within the circuit design, whereby registers are moved across one or more portions of the combinational logic. When moving the registers, counter values may be maintained for a group of non-justifiable elements within the combinational logic, across which the registers may move. The counter values may be maintained and updated on a per element, per clock domain basis to account for register moves across the corresponding non-justifiable elements. The maximum counter value for each clock domain may be chosen as an adjustment value that may be used to generate an adjustment sequence. The adjustment sequence may be prepended to the original reset sequence to generate an adjusted reset sequence that properly resets registers within the integrated circuit after registers moves.
