Abstract: Autonomous machine navigation techniques may generate a three-dimensional point cloud that represents at least a work region based on feature data and matching data. Pose data associated with points of the three-dimensional point cloud may be generated that represents poses of an autonomous machine. A boundary may be determined using the pose data for subsequent navigation of the autonomous machine in the work region. Non-vision-based sensor data may be used to determine a pose. The pose may be updated based on the vision-based pose data. The autonomous machine may be navigated within the boundary of the work region based on the updated pose. The three-dimensional point cloud may be generated based on data captured during a touring phase. Boundaries may be generated based on data captured during a mapping phase.

Abstract: A system for managing a battery removal from an electronic device is provided. The electronic device includes a battery interface including multiple battery coupling contacts that engage with battery contacts of the battery in an installed position of the battery. A battery removal detector is configured to detect, based on signals received via the battery interface, an ongoing battery removal process during which first battery contact(s) are disconnected from corresponding first interface contact(s) while second battery contact(s) remain connected with second battery coupling contact(s), and in response, to output a battery removal signal. The system also includes a controller that receives the battery removal signal and, still during the battery removal process, controls a memory device of the electronic device to prevent or complete a defined operation (e.g., writing of persistent storage keys) prior to completion of the battery removal process, to thereby prevent a corruption of the memory device.

Abstract: Apparatus and associated methods relate to a risk trace matrix engine for managing database associations, in a quality management system (QMS), between risk mitigations and features of a system having a risk-based profile. In an illustrative example, metadata may be created to associate risk mitigations with elements of a product and then metadata may be stored in a database during the design or operating lifecycle of the product, for example. The engine may dynamically build one or more trace matrices for the product design, each matrix associating risk mitigations to elements of the product design documentation. In response to any modifications that may relate to the component's specifications, for example, the engine may retrieve associated metadata and generate notifications prompting for user verification.

Abstract: A design for the electrical infrastructure of a data center enables two different configurations to be utilized, including a distributed, redundant configuration that provides higher reliability and a non-redundant configuration that provides higher capacity. In the distributed, redundant configuration, each server in the data center draws power from at least two different power supply systems. This enables load shifting when a power supply system becomes unavailable, which can have the effect of increasing server reliability. In the non-redundant configuration, each server in the data center draws power from only one power supply system. Load shifting is not utilized in the non-redundant configuration, which eliminates the need to maintain reserve capacity and thereby increases capacity. Advantageously, it is possible to switch between these two configurations without making any internal changes to the data center other than modifying connections between sets of server racks and power buses.
