Abstract: Disclosed is a tube/tube connector/capsule port assembly that eliminates a connection point in a filter capsule apparatus. A relatively soft tube is thermally or sonically bonded to a relatively hard tube connector that may have a tube receiving bore, frustoconical tube receiving channel or straight tube receiving channel. The tube connector is bonded to a filter capsule port. The manufacturing process can be either a one-step process bonding the tube, tube connector and capsule in one step, or a two-step process that binds the tube to the tube connector in the first step and they binds the tube/tube connector subassembly to a filter capsule housing during the housing's molding procedure. Single and dual-walled tubes may be used as well as single and dual-walled tubes having reinforcing material superposed about or embedded in the tube wall(s). A tube support collar is also disclosed.

Abstract: In particular embodiments, a user associated with a user account wishes to utilize their computing device to facilitate authentication of their identity. The user may provide a device key to an online system hosting the user account, wherein the device key uniquely identifies their computing device. The device key may be based on a device identifier encoded in hardware of the computing device. The online system may then store the device key in association with the user account. Subsequently, if an action related to the online system requires authentication, the user may be asked to provide authentication using their computing device. The user generates an authentication code using their device, which can be entered by the user into a user interface for comparison against an authentication code generated using the device key stored by the online system.

Abstract: A bio-reactive container and filter assembly to improve flow rates and mass transfer without increased pressure. An inlet filter membrane secured to the container defines a container chamber in combination with the container. An inlet filter membrane element may also be secured to the container to provide structural support to the membrane. An outlet membrane secured to the container defines a container chamber in combination with the container. An outlet filter membrane element may also be secured to the container to provide structural support to the outlet membrane. Inlet and/or outlet filters and/or filter elements are constructed to significantly increase surface area available for fluid and/or gas ingress and/or egress. Single and double layer membranes with mixtures of hydrophobic and hydrophilic characteristics are used to maximize perfusion and gasification/degasification of bio-reactive containers.

Braze methods further include at least partially covering the pre-sintered preform with a heat resistant material, wherein a melt temperature of the heat resistant material is higher than a melt temperature of the pre-sintered preform, and heating the pre-sintered preform on the substrate.

Abstract: One or more techniques and/or systems are provided for dynamically maintaining user centric data. For example, a data provider app may have knowledge about user centric data associated with a user (e.g., a social network app may have contact information for a social network friend of the user). A user centric profile may be defined for the user centric data based upon information provided by the data provider app (e.g., a contact card may be generated for the social network friend). Responsive to receiving a request for the user centric profile from a requestor app (e.g., an event planning app), the user centric profile may be exposed to the user but not to the requestor app for security and/or privacy purposes. For example, an operating system may present at least some of the user centric profile within an operating system user interface.

The online system may apply one or more rules based on user perception of characteristics when selecting the one or more characteristics included in the description. An option for the user to prevent use of the selected one or more characteristics when the online system subsequently selects advertisement content for the user is also presented with the description.

Abstract: A model based social analytic system collects social signals from social network accounts for different companies and constituents. The social signals can be used to benchmark social network performance for different contextual dimensions, such as industries, companies, brands, etc. Conversations may be identified in the signals and the types of constituents participating in the conversations may be identified. Analytics can then be determined for the contextual dimensions based on the related conversations and the types of constituents participating in the conversations.

Abstract: A system may include at least one computer device configured to attain a two-dimensional used profile of a leading edge at a specified radial position on a turbomachine airfoil after use. The system aligns opposing substantially straight alignment portions of the two-dimensional used profile with opposing substantially straight alignment portions of a previously attained, two-dimensional, baseline profile of the turbomachine airfoil. The alignment portions of each profile are in substantially identical radial locations of the turbomachine airfoil. Comparing the used profile to the baseline profile determines whether the leading edge at the specified radial position of the used turbomachine airfoil has erosion. The system may also include a laser profiler for measuring the turbomachine airfoil.

Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid.

Abstract: An online services system includes a mechanism for providing user confidence information to an external data consumer, and for determining user contribution quality. Using stored information about user actions and interactions, user confidence is evaluated for one or more parameters associated with the validity of the user's account and/or quality of the user's contributions to the online services system. Confidence values are assigned to each parameter, and the values are exposed to external data consumers. Using stored information, user actions and interactions are correlated with contribution quality to produce a metric indicative of user contribution quality. Users with low quality parameter metrics may have their contributions shown to a smaller audience or have a lower prominence in a news feed.

Abstract: One or more techniques and/or systems are provided for dynamically maintaining a service profile. That is, a user may be associated with a variety of services, such as an email service, a social network service, a photo sharing service, etc. An operating system may dynamically provide support for services by maintaining service profiles. For example, a service provider application may specify a service definition defining a service not yet supported (e.g., a social network app may describe functionality and/or information about a new social network service). A service profile may be generated for the service based upon the service definition. The service profile may be exposed to system components and/or applications that may utilize the service profile to access information and/or functionality provided by service (e.g., a camera system component may allow a user to upload a photo to the new social network service utilizing the service profile).
