Abstract: This disclosure is generally directed to systems and methods for using an autonomous vehicle to provide navigation assistance to a delivery robot. In one exemplary implementation, the delivery robot is transported by the autonomous vehicle to a delivery destination such as a residence or a workplace. The delivery robot disembarks at the delivery destination for delivering a package to a recipient at the residence or workplace. A computer system in the autonomous vehicle communicates with a navigation assistance system of the autonomous vehicle to obtain information pertaining to a terrain between the autonomous vehicle and a package drop-off spot at the residence or workplace, and uses the information to generate a route map of the terrain. The autonomous vehicle may transmit the route map and/or navigation instructions derived from the route map, to the delivery robot to assist the delivery robot navigate around obstacles and reach the package drop-off spot.

At least one of the network digital video recorders may determine whether, based on a network capacity, to record, archive, and/or playback content items. The methods, systems, and apparatuses may accommodate equipment failures that lead to partitions between network digital video recorders.

Abstract: A computer system receives data identifying data fields used by sources of data and infrastructure information. The computer system maintains a storage state database to track information about the data fields. The computer system provides a graphical user interface through which a user can create, view, modify, and delete data defining classes and rules associated with classes. The computer system applies the rules to classify the data fields. The computer system provides a graphical user interface through which the classification of the data fields can be visualized in the context of infrastructure information for the sources of data.

Abstract: Intelligent assistant devices and methods for interacting with a user are disclosed. In some examples, a method for interacting with a user comprises predicting suggested action(s) for the user and displaying the action(s) via a display of the device. While the suggested action(s) are displayed, audio input comprising a command followed by a keyword is received from the user. The audio input is processed locally on the intelligent assistance device to (1) determine that the keyword follows the command and (2) recognize that the command applies to the suggested action(s). Based on determining that the keyword follows the command and recognizing that the command applies to the suggested action(s), a user selection of the suggested action(s) is established. Based on establishing the user selection, the one or more suggested actions are executed.

Different V-shapes can be used for the first and second cross-sectional shapes, the openings of the V-shapes facing in a forward rotational direction of the rotor. Multiple pairs of similarly shaped paddles can be used.

Abstract: Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

Abstract: A vehicle hitch assistance system includes a powered suspension system supporting a rear of the vehicle at a height and a controller. The controller acquires position data for a coupler of a trailer, determines when the position data indicates that a hitch ball of the vehicle is aligned with the coupler, and causes the powered suspension system to raise the height of the rear portion of the vehicle until a threshold resistance value is detected.

Abstract: Methods of modulating the immune systems of patients suffering from cancers that do not bear, or do not uniformly bear, surface CD3 are provided. The methods involve administering an anti-CD3 immunotoxin (e.g. A-dmDT390-bisFv(UCHT1)), to the patient so as to cause the patient's immune system to recognize and destroy non-CD3 cancer cells.

Abstract: A technique controls a new software build. The technique involves receiving abstract hash values for source code components. Each abstract hash value is derived from a most recent source code version of a respective source code component. The technique further involves generating new build fingerprints based on the abstract hash values. The new build fingerprints are different from the abstract hash values received for the source code components. The technique further involves building particular software components of the new software build based on comparisons between the new build fingerprints and respective previous build fingerprints generated during a set of previous software builds.
