Abstract: Systems and methods permit generation of a digital scan of a user's face such as for obtaining of a patient respiratory mask, or component(s) thereof, based on the digital scan. The method may include: receiving video data comprising a plurality of video frames of the user's face taken from a plurality of angles relative to the user's face, generating a three-dimensional representation of a surface of the user's face based on the plurality of video frames, receiving scale estimation data associated with the received video data, the scale estimation data indicative of a relative size of the user's face, and scaling the digital three-dimensional representation of the user's face based on the scale estimation data. In some aspects, the scale estimation data may be derived from motion information collected by the same device that collects the scan of the user's face.

Abstract: In exemplary implementations, a target rod is actuated. The target rod is part of a set of threaded, elongated rods, the longitudinal axes of which are substantially parallel to each other. The set of rods has an interior region and a perimeter region. Actuators induce vibrations in a set of perimeter rods. These vibrations are substantially perpendicular to the longitudinal axes. Furthermore, the vibrations are transmitted to interior rods, causing a target rod in the interior region to rotate about, and translate along, the longitudinal axis of the target rod. The target rod undergoes stick-slip motion relative to adjacent rods.

Abstract: A messaging system facilitates communication between users through various messaging channels. The messaging system supports multiple communication channels and includes a messaging module that automatically selects one or more of the messaging channels for delivering a message to a recipient of the message using, for example, a set of policy rules or a trained model. The messaging module may also provide, in a user interface for sending and receiving messages, a visual indication of the selected messaging channel to the sender of the message to provide the user with transparency about how the message will be delivered. Additionally, the message may be delivered via multiple messaging channels, where the messaging module may rescind messages from some of the messaging channels upon receiving a reply from the recipient of the message or other confirmation that the recipient has seen the message via one of the communication channels.

Abstract: In exemplary implementations of this invention, an actuated fabricator deposits structural elements (e.g., tensile structural elements) in a 3D pattern over large displacements. The fabricator is supported by at least three elongated support members. It includes onboard actuators that translate the fabricator relative to the ends of the support members. The fabricator is configured, by actuating different translations along different support members, to translate itself throughout a 3D volume. In some implementations, each of the actuators use fusible material to fuse metal tapes together, edge-to-edge, to form a hollow structure that can be shortened or lengthened.

Abstract: A social networking system determines common location information included in a set of posts between a set of users. Using the determined common location information, the social networking system generates a message interface for grouping a set of messages into a conversation thread. For example, the messages may be grouped into a conversation thread based on common location information in the messages and being associated with participants sharing a social relationship. When a group conversation is created, the social networking system presents a message interface containing the conversation thread to one or more participants of the thread. The social networking system adds the set of messages to the conversation thread based on social information about the social relationships among the participants of the conversation thread. The social networking system then presents the message interface for display to one or more of the participants.

Abstract: Embodiments include a computer-implemented method for identifying locations of infrastructure assets. The method including identifying a location of a first infrastructure asset and a location of a second infrastructure asset, identifying a region of interest extending at least partially between the locations of the first and second infrastructure assets, obtaining an aerial image of the region of interest, determining that the aerial image of the region of interest comprises a third infrastructure asset, determining a location of the third infrastructure asset based at least in part on the aerial image, and storing the location of the secondary infrastructure asset in an infrastructure asset datastore.

Abstract: A social networking system identifies an event based on a thread including messages from users of the social networking system and communicates invitations to the event to one or more invited users. The social networking system receives a response to an invitation from a responding user and identifies a group of users invited to the event that have not responded to the invitation. From the users invited to the event that have not responded to the invitation, a subset of users having a threshold affinity to the responding user are selected. The social networking system notifies the subset of users of the responding user's response to the invitation and may also provide the subset of users with a suggestion for attending the event.

Abstract: A method for determining hydraulic compliance of a wellbore during a managed pressure drilling procedure. Measurements are made of the pressure of a drilling fluid being circulated in the wellbore during the procedure at the top of a drilling annulus, the flow rate qin of the drilling fluid into the wellbore and the flow rate qout of the fluid out of the wellbore. These three measurements are used to determine the difference of the flow rates and a discrete time derivative (Pt?Pt-?t)/?t of the pressure, where t is time and ?t is a time interval. The differences in flow rates and the time derivatives are then processed by applying a low pass filter to determine the hydraulic compliance of the wellbore.

Abstract: Users of a social networking system initiate conversations between other users and additional users who may not be registered to use the social networking system. Each additional user is identified by an item of contact information, and conversation messages are sent to an additional user using the contact information. The conversations are associated with the item of contact information and saved in the social networking system. A user of the social networking system may subsequently claim the item of contact information. The claiming user is given access to the associated conversations if the social networking system can verify that the item of contact information belongs to the claiming user.

Abstract: Pipes, drill strings including pipes, and methods for use on a drilling rig. The method includes obtaining pipe data for individual drill pipes of a drill string, obtaining a well trajectory for a well, obtaining one or more drilling measurements to be used when drilling the well, planning a first drill string based on the pipe data, the well trajectory, and the one or more drilling measurements, predicting an aging of the individual drill pipes in the first drill string while drilling the well using the first drill string, determining that a risk of failure of one or more individual pipes in the first drill string is unacceptable based on the aging of the individual pipes; and planning a second drill string in response to determining that the risk of failure is unacceptable in the first drill string.

Abstract: A social networking system generates an augmented user profile for a user. The augmented user profile includes information from user profiles maintained by additional social networking systems that correspond to the user of the social networking system. For example, user profiles maintained by additional social networking systems having a threshold similarity to a user profile maintained by the social networking system are identified, and characteristics of the user in the identified user profiles are included in the augmented user profile along with characteristics from the user profile maintained by the social networking system. Characteristics of the user from the augmented user profile are used to identify content, such as advertisements, for presentation to the user.
