Abstract: A map processing device obtains images from a camera transported with a mobile device, and detects 2D features in the images. At least some of the 2D features detected in the images are densified to generate a densified set of 2D features. Locations of the densified set of 2D features are determined in 3D space using an image-based localization algorithm. A structure-based map comprising depth information from a depth sensor transported by another mobile device is accessed, wherein the depth information includes a set of data points indicating locations in 3D space corresponding to features in the real-world sensed by the depth sensor. The camera transported with the mobile device is localized to the real-world based on matching the locations of the densified set of 2D features in 3D space to the depth information accessed in the structure-based map.

Abstract: Systems, methods, and apparatus for fault detection and interruption in power lines are provided. Circuitry is implemented via software and hardware that is configured to sense an operational aspect of a power line, such as current levels in a three-phase power line, and apply signal processing to the sensed operational aspect to detect faults including different types of faults such as transient and steady state faults and can also be configured to identify the type of fault. Information on the fault and the identification of the type of fault can be displayed, stored, or some other output operation can be implemented. Circuitry can be implemented to provide digital signal processing and analog signal processing to, for example, independently and in parallel (e.g., redundant operation) detect faults and respond to faults as they occur (i.e., in real time).
