摘要:
A social networking system includes a mechanism for integrating user actions on objects outside of the social networking system in the social graph. External system operators include widgets that, when executed by user devices, record user interactions that correspond to a defined structure of actions and objects. Information about the actions and the objects is gathered from external systems as users of the social networking system interact with the external systems. Content items are ranked according to the information about the actions and the objects as well as preferences of the viewing users.

Exemplary methods, apparatuses, and systems receive a first user action, by a user within a network service, with respect to a first object displayed or referenced on the network service. Demographic information for the user is received and a counter for a category representing the first user action, the first object, and the demographic information is identified and incremented. The demographic information may include a history of a second user action with respect to a second object. Counters with the highest values for a category represent the highest ranked objects in the category. Upon receipt of a request for a number of objects for the category, objects that correspond to counters with the highest values for the category are selected and transmitted as a ranked list of recommended objects for display by a user.
摘要:
Bearing sealing structures are disclosed, which may include first and second frameworks configured to attach to an outer ring and an inner ring, respectively, and an elastic sealing member. The first framework may include a first radially extending part extending towards the inner ring, the second framework may include a second radially extending part extending towards the outer ring, and the second radially extending part may be located on an axially outer side of the first radially extending part. The sealing structure may form a first chamber and a second chamber in a radial direction, the first chamber being formed by the first or second radially extending part. The second chamber may be located on a radially inner side of the first chamber, and the elastic sealing member may include a first sealing member extending into the first chamber and a second sealing member extending into the second chamber.

A preconnectorized outdoor cable streamlines the deployment of optical waveguides into the last mile of an optical network. The preconnectorized outdoor cable includes a cable and at least one plug connector. The plug connector is attached to a first end of the cable, thereby connectorizing at least one optical waveguide. The cable has at least one optical waveguide, at least one tensile element, and a cable jacket. Various cable designs such as figure-eight or flat cables may be used with the plug connector. In preferred embodiments, the plug connector includes a crimp assembly having a crimp housing and a crimp band. The crimp housing has two half-shells being held together by the crimp band for securing the at least one tensile element. When fully assembled, the crimp housing fits into a shroud of the preconnectorized cable. The shroud aides in mating the preconnectorized cable with a complimentary receptacle.
摘要:
This invention relates to a cationically and amphiphilically modified polygalactomannan having repeating units with an average D-mannosyl to D-galactosyl residue ratio of at least 5 to 1 and to compositions containing same. A portion of the hydrogen atoms of hydroxyl groups situated on the mannosyl and galactosyl residues of the galactomannan are replaced with an amphiphilic and a cationic substituent.

A ruggedized fiber optic connector assembly includes a substantially hollow plug housing; and a glue body disposed within the substantially hollow plug housing; wherein the glue body includes a first portion that is configured to engage and retain an optical cable comprising an optical fiber and one or more strength members; wherein the glue body includes a second portion that is configured to engage and retain a connector sub-assembly comprising an optical ferrule; wherein the second portion of the glue body includes a pair of opposed snap hooks that are configured to engage a corresponding pair of opposed recesses of the connector sub-assembly; and wherein the optical fiber and the optical ferrule are optically coupled.
摘要:
A circuit for detecting out-of-band signals is disclosed. In one embodiment, the circuit includes a first differential circuit configured to level shift and positively rectify a differential input signal to produce a first output component of a differential output signal. The first differential circuit is further configured to generate and provide a common mode voltage of the differential input signal as a second component of the differential output signal. The circuit further includes a second differential circuit configured to level shift and output first and second fixed voltages based on an input reference voltage and a ground voltage. The circuit is configured to provide the differential output signal and the first and second fixed voltages to an indicator circuit configured to assert an indication responsive to detecting that a differential voltage of the differential output signal is greater than a differential voltage of the first and second fixed voltages.
