Abstract: Systems, methods, and non-transitory computer readable media are configured to maintain a plurality of templates that specify presentation of types of content items in a news feed, each template of the plurality of templates having an identifier. An identifier of a template associated with a content item to be presented in the news feed is received. It is determined whether the identifier of the template associated with the content item matches an identifier of a template of the plurality of templates.

Abstract: A user requests a package delivery from a package delivery system. The package delivery system provides the user with a machine-readable code for display at the delivery location. An aerial delivery device receives, from the package delivery system computing device, information associated with the delivery location of the package. The information comprises information matching the information in the machine-readable code associated with the delivery location and a delivery address. The delivery device secures the package for transporting to the delivery location and transports the package to the delivery address. The delivery device locates the machine-readable code on a display at the delivery address and verifies that the information from the machine-readable code is associated with the package. The delivery device deposits the package on the display.

The inner flow path has cross-sections that are generally cylindrical and also has sections of removed material.

Abstract: In a client device having one or more processors and memory storing instructions for execution by the one or more processors, graphic icons of one or more users who have provided user feedback for a first content item are displayed. The client device transitions from displaying one or more of the graphic icons to displaying user feedback for the first content item provided by respective users.

Abstract: Apparatus and associated methods relate to determining, based on a spatial extent of ice accretion, whether an atmosphere contains super-cooled water droplets that equal and/or exceed a predetermined size. A convex-shaped housing is mounted to an aircraft and exposed to an airstream. The convex-shaped housing has a testing region that is monitored for ice accretion by an ice detector. A boundary locator determines a specific location to be tested within the testing region. The determined specific location corresponds to a calculated boundary that separates an ice-accretion region from an ice-free region if the atmosphere contains super-cooled water droplets up to the predetermined size. If the ice detector detects ice accretion at the determined specific location, an alert is generated. The alert can advantageously inform a pilot of an atmosphere containing super-cooled water droplets that equal or exceed the predetermined size.

Abstract: A client device having a touch-sensitive display displays (i) multiple affordances in a first area of the touch-sensitive display and (ii) a content item in a second area of the touch-sensitive display. The affordances include a user-feedback affordance for providing feedback about the content item. The device detects a first user input at the user-feedback affordance. In response, the device displays a first facial expression superimposed on the content item. Concurrently, the device replaces display of the affordances with a range of facial expressions, each facial expression in the range corresponding to a respective opinion of a range of opinions. The device detects a second user input at a location of a second facial expression in the displayed range of facial expressions. The second facial expression is different from the first facial expression. In response, the device displays the second facial expression superimposed on the content item.

Abstract: A computer-implemented technique is described herein for presenting notifications on a user interface presentation of a recipient computing device. The technique is considered tiered because it distinguishes between first-type (people-centric) notifications and second-type notifications, and because it processes and presents first-type notifications in a privileged manner compared to the second-type notifications. For instance, the technique presents content associated with each first-type notification in an allocated window that appears in positional association with a person indicator, where that person indicator identifies the person who sent the first-type notification; the technique presents each second-type notification in a different manner. In some implementations, an application developer who designs a custom first-type notification is given authority to draw within the allocated window that is used to present the custom first-type notification in a manner specified by the application developer.

Abstract: Methods and systems to detect power outage are provided herein. The system includes a Cable Modem Termination System (CMTS) to periodically poll cable modems and determine cable modems of the plurality of cable modems that are offline based on the poll. The system correlates and aggregates locations of the cable modems that are offline to determine a geographic area where a percentage of the cable modems that are offline is higher than a predetermined threshold. A report is generated indicating a power outage in the geographic area when the percentage is above the pre-determined threshold.

The primary low ice adhesion surface coating has a different composition than the secondary low ice adhesion surface coating.

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: Systems and methods for authenticating access to multiple data stores substantially in real-time are disclosed. The system may include a server coupled to a network, a client device in communication with the server via the network and a plurality of data stores. The server may authenticate access to the data stores and forward information from those stores to the client device. An exemplary authentication method may include receipt of a request for access to data. Information concerning access to that data is stored and associated with an identifier assigned to a client device. If the identifier is found to correspond to the stored information during a future request for access to the store, access to that store is granted.

Abstract: A method displays a first story, which is a republication of a second story and an indication of a previous user interaction with the second story that resulted in creating the first story. The method displays a compressed view of a first user-feedback interface, corresponding to the first story, including affordances for providing user feedback regarding the first story, and displays a compressed view of a second user-feedback interface, corresponding to the second story, including affordances for providing user feedback regarding the second story. The method detects user selection of either the first user-feedback interface or the second user-feedback interface. In response, the method displays an expanded view of the selected user-feedback interface while displaying the compressed view of the user-feedback interface not selected.
