Abstract: A load-monitoring system includes a vehicle processor and a camera mounted in a trailer. The vehicle, via the processor, displays a first image of a trailer load, received from a trailer-mounted camera and receives selection of a monitoring point on the image, via a touch-sensitive user interface displaying the image or other selection mechanism. The vehicle also receives selection of a fixed point on the image, via the user interface. If the monitoring point moves more than a threshold amount, relative to the fixed point, for example, in subsequent images captured by the camera, the vehicle alerts the driver.

Abstract: Aspects of the disclosure relate to training and using a model for identifying actions of objects. For instance, LIDAR sensor data frames including an object bounding box corresponding to an object as well as an action label for the bounding box may be received. Each sensor frame is associated with a timestamp and is sequenced with respect to other sensor frames. Each given sensor data frame may be projected into a camera image of the object based on the timestamp associated with the given sensor data frame in order to provide fused data. The model may be trained using the fused data such that the model is configured to, in response to receiving fused data, the model outputs an action label for each object bounding box of the fused data. This output may then be used to control a vehicle in an autonomous driving mode.

Abstract: Fault detection, isolation and restoration systems for electric power systems using “smart switch” points that autonomously coordinate operations to minimize the number of customers affected by outages and their durations, without relying on communications with a central controller or between the smart switch points. Each smart recloser can be individually programmed to operate as a tie-switch, a Type-A (normal or default type) sectionalizer, or a Type-B (special type) sectionalizer. The Type-A recloser automatically opens when it detects a fault, uses a direction-to-fault and zone-based distance-to-fault operating protocol, and stays “as is” with no automatic opening when power (voltage) is lost on both sides of the switch. The Type-B sectionalizer does the same thing and is further configured to automatically open when it detects that it is deenergized on both sides for a pre-defined time period, and to operate like a tie-switch once open.
