Abstract: The present disclosure is directed to systems and methods for providing dynamic communication threads in response to a detected interaction with a sponsored digital content item. For example, systems and method described herein detect a user interaction with a sponsored digital content item and generate a screened communication thread between the user and the sponsor that is not available to the sponsor. The screened communication thread serves as a reminder to the user of the sponsored digital content item. Systems and methods described herein convert the screened communication thread to an open communication thread based on user interaction with the screened communication thread (e.g., after the user submits a reply in the screened communication thread). Thus, systems and methods described herein protect the user's online privacy unless and until the user indicates a desire to interact with the sponsor.

Abstract: The current invention is a method and system for optimally isolating adult derived stem cells from whole blood and reintroducing the adult derived stem cells into a subject at specific target areas having damaged tissue to be repaired.

Abstract: A flywheel device includes structures allowing the flywheel system to be assembled offsite, transported safely, and installed with relatively few steps. The flywheel includes a rotor and a housing enclosing the rotor, where the housing includes a bottom plate, a top plate and side walls. The bottom plate and the top plate each includes a hole aligned with the center axis of the rotor. The flywheel also includes multiple bearing housings substantially covering the holes of the bottom plate and the top plate that are aligned to the center axis of the rotor. The flywheel also includes posts that physically contact the primary rotational mass of the rotor to prevent motion of the rotor during transport of the flywheel system. Some or all of these posts may be repositioned or removed during installation so that the rotor can spin freely.

Abstract: In one embodiment, a method includes launching, by a client system of a first user, a video-call session to enable a video stream for display in a small-overlay-window on a display of the client system of the first user; receiving, by the client system of the first user, a video stream comprising video from a client system of a second user; determining at least one property for the small-overlay-window based on information associated with the second user; and displaying the video stream in the small-overlay-window, wherein the small-overlay-window is customized based on the determined at least one property, and wherein the small-overlay-window is positioned directly over an interface of an active application running on the client system of the first user.

Abstract: In one embodiment, a method includes launching, by a client system of a first user, a video-call session; receiving, by the client system of the first user, a video stream including video captured at a client system of a second user; and displaying the video stream in a small-overlay-window on a display of the client system of the first user, wherein the small-overlay-window is positioned over an active application.

Abstract: An energy storage system including a solid steel flywheel rotor, journals, and separate stub shafts for connecting to the journals has improved material properties offers improved energy storage at reduced cost.

Abstract: Embodiments of the subject invention are directed to a flywheel rotor that includes two or more sub-rotors stacked one on top of another, in which each sub-rotor is rotationally symmetric and disk shaped, where the axial centers of each sub-rotor in the stack are rotationally aligned, and each sub-rotor has an upper and a lower journal that extends outward from the origin of the center section of the primary rotational mass of the sub-rotor. Each pair of adjacent sub-rotors in the stack has a lower journal of an upper sub-rotor that is disposed above an upper journal of a lower sub-rotor. Also, there is a joining mechanism between each pair of adjacent sub-rotors that fixedly connects the lower journal of the upper sub-rotor to the upper journal of the lower sub-rotor.

Abstract: Exemplary embodiments provide techniques for promoting and providing subscribed content via a messaging platform. An article may be viewed via a social networking service (such as in a social network's news feed), or on a partner website integrated with the social networking service and/or messaging service. When opening the article (e.g., in a web-based view), a banner may be displayed in association with the article indicating that the article could have been received as part of a messaging-based subscription service. The banner may include a control to subscribe to the publisher with the messaging service. Topics related to an article may be suggested in the message thread for the subscription, with the selection of a topic retrieving additional articles from that publisher related to that topic. These additional articles may be selected using social networking topic determination.

Abstract: Exemplary embodiments relate to techniques for providing search results, such as when performing a type-ahead search. If an exact match to the search query is available, the exact match is used. If no exact match exists, search results are prioritized based primarily on responsiveness and pixel data, and secondarily based on metrics including locale/location, fancount, and social signal information. If a user searches for an entity having multiple results, the system will attempt to find a local result that is proximate to the user, but will prioritize a search hit for a more responsive result over other results. This boosts the chance that the user will get a response if they leave a message for the searched entity. Entities may be omitted from search results if they are unable to send or receive messages.

Abstract: A user of a user device with a first account with an online service selects a contact to invite to join the online service. A server receives the selected contact to invite from the user device, and in response to receiving the selected contact, generates a second account for the selected contact. The second account includes a plurality of fields, one or more of which are populated with contact information of the selected contact. A link to the second account is generated and provided in an invitation for the selected contact to activate the second account with the online service.

Abstract: The present disclosure is directed toward systems and methods for reengaging website visitors via a social networking system. For example, in accordance with one embodiment, a social networking system receives information regarding a user-triggered event associated with a merchant webpage, utilizes the received information to generate an electronic message from the merchant to the user, and provides the electronic message to the user via the social networking system. The user can then reengage with the merchant in response to the received electronic message.

Abstract: One or more embodiments of the disclosure provide a promotional messaging system for efficiently providing promotional messages to customers via an electronic messaging system. For example, in one or more embodiments, the promotional messaging system identifies users of the electronic messaging system that have previously communicated with a merchant as part of a customized audience. Additionally, in some embodiments, the promotional messaging system analyzes activity patterns of the users to provide improved delivery of promotional messages in a non-intrusive, private, and timely manner. Overall, the promotional messaging system described herein improves communications via an electronic messaging system between users and a merchant.
