Abstract:

A vehicle computing system validates location data received from a Global Navigation Satellite System receiver with other sensor data. In one embodiment, the system calculates velocities with the location data and the other sensor data. The system generates a probabilistic model for velocity with a velocity calculated with location data and variance associated with the location data. The system determines a confidence score by applying the probabilistic model to one or more of the velocities calculated with other sensor data. In another embodiment, the system implements a machine learning model that considers features extracted from the sensor data. The system generates a feature vector for the location data and determines a confidence score for the location data by applying the machine learning model to the feature vector. Based on the confidence score, the system can validate the location data. The validated location data is useful for navigation and map updates.

Abstract:

A reservoir for containing a fluid includes a cylindrical wall sized to engage a shaft bored into ground, a bottom end cap fixed to a lower end of the cylindrical wall and a top end cap fixed to an upper end of the cylindrical wall. The top end cap is concave such that the top end cap extends below a top end of the cylindrical wall. The bottom end cap, the top end cap, and the cylindrical wall define a subterranean chamber. A plug made of a composite material is on the top end cap, with a lower face disposed on the concave top end cap and a peripheral face engaging the shaft. At least one pressure port extends downwardly into the shaft and through the plug and the top end cap, defining a fluid path to the subterranean chamber.

H04L 29/08

Abstract:

In one embodiment, a method includes receiving from a client computing device a request to upload a multimedia file from the client computing device to a service. The method includes identifying transcoding servers configured to receive and transcode multimedia files from client computing devices and store the transcoded multimedia files. The method includes sending a reply to the client computing device that includes job configuration information that includes an access token authorizing the client computing device to access the transcoding servers. The information specifies upload policies that include failover instructions for if a failure occurs during an upload from the client computing device to a first of the transcoding servers. The failover instructions include sending the access token to the first of the transcoding servers to resume the upload or sending the access token to a second of the transcoding servers to restart the upload.
