Component mounter
In a component mounter, a gap between adjacent circular plate sections of nozzles is large enough such that a pressing roller is able to pass through in a vertical direction. Therefore, the size of a circular plate section can be made relatively small, and a rotary head can be made small. A horizontal protrusion overlaps with one or both of adjacent ring-shaped protrusions of the nozzle when viewed from above in a case in which the pressing roller is positioned between adjacent circular plate sections of nozzles. In a state with the pressing roller positioned above the gap between adjacent circular plate sections of nozzles, even if power to a Z-axis linear actuator is cut such that the raising and lowering member suddenly loses support and falls, the horizontal protrusion of the raising and lowering member engages with and stops the ring-shaped protrusion of the nozzle. |

A redirection of a URL page request may be performed by monitoring an upstream path from a subscriber to the internet through an ISP. When a URL page request is detected from a subscriber for whom a redirection is required, a redirection device generates a single TCP packet response that mimics a response from the intended destination server. The single TCP packet includes a set FIN bit that closes any active session with the destination server to prevent the subscriber from accepting packets from the destination server. |

Social signature
The disclosure is directed to determining a social signature of a user of an application, e.g., a social networking application. The social signature can be a representation of social properties of a person, and can be determined based on various factors, e.g., user profile of the user and friends of the user. The social signature can be used for various applications, e.g., determining socially similarity of a user pair and determining if a user is a spammer. The social signature is determined as a vector of k buckets in which each of the k buckets indicates a count of friends of the user assigned to the corresponding bucket. A social similarity of a user pair is determined as a function of the social signatures of the user pair. A user is determined as likely to be a spammer if the social signature of the user is of a specified pattern. |

Integrating third-party vendors' APIs
Integrating third-party vendors' APIs is described.

Determining accuracy of characteristics asserted to a social networking system by a user
A social networking system maintains characteristics with its users, with various characteristics, such as age, specified by the users (i.e., “asserted characteristics”). The social networking system selects content for a user based at least in part on the characteristics associated with the user. To account for potential inaccuracies in an asserted age of a user, the social networking system clusters users based on ages of other users connected to users. The online system receives verified ages for users in a cluster from a trusted third party system that maintains more accurate characteristics for users than the social networking system. By comparing the asserted ages for users in the cluster to the verified ages for users in the cluster, the social networking system determines an accuracy of the asserted ages for users in the cluster. The accuracy may be used when selecting content for the users. |

Information is removed from data transmitted over networks and stored in data storage facilities by generating non-informational data as an output from a series of nodes (routers, computing devices or logical routing applications) by using a function that applies random data to the data received at each node. The function may be an XOR and the random data may be a pseudorandom string of the same length as the informational data. The non-informational data may be managed normally without concern for security. When the informational data is needed it can be re-generated using the non-informational data and a cascade of the random data from the series of nodes as inputs to an inverse function (XOR is its own inverse). The random data may be generated from a smaller random seed. |

Compact stabilized pointing system
The preferred field of application of the present invention concerns the technology for the stabilization of the orientation of a pointing platform in small satellites as, for example, the so-called nano-satellites. In fact, the use of nano-satellites for low-cost space applications, requires that they have performances suitable to support a large number of possible new applications, in particular it is required that they can ensure adequate telecommunications capacity even with scarce power resources. Therefore, the availability of very precise pointing systems is essential in order to make communications as efficient as possible. Moreover, it should be noted that the nano-satellite platforms are also very unstable, and therefore such pointing, when acquired, must be continuously stabilized. Finally, the pointing and stabilization mechanisms must be light and compact in order to meet other typical constraints (weight and size, precisely) of space applications, but which may also be present in other areas of application. The mechanism specified in the present invention provides an adjustable support platform constrained to the satellite platform (or in general to an unstable platform) in one of its points by means of a joint with two or three degrees of freedom. The orientation and the stabilization of such orientable platform are then controlled by other constraints which consist in extensible legs with a controllable length. The mechanism, as a whole, provides a satisfactory solution to the problem of the stabilized pointing and allows, at the same time, to significantly reduce the weight and the overall dimensions. |

The portions of the plastic layer that cover the distal end faces in the protruding direction of the ribs each have a cooling passage, which causes cooling water in the flow path to flow to the space between those portions of the plastic layer and a contact surface of the end in the cell stacking direction of the cell stack. |

Scalable micro power cells with no-gap arrangement between electron and proton transfer elements
A power cell and a method for fabricating a power cell including two body portions and a proton exchange membrane (PEM) there between. The body portions each include a reaction chamber for holding an anolyte solution including a photosynthetic organism or a catholyte solution. At least one body portion has an optically transparent window to allow light into the reaction chamber enabling a photosynthetic reaction. A thin metal layer is coated directly on each of first and second surfaces of the PEM and then the two body portions are coupled together with the PEM located there between. Coating the first thin metal layer on the surfaces of the PEM involves coating a thin gold layer onto the surface, covering the gold layer with a layer of photoresist, patterning the photoresist layer through a mask, exposing the photoresist layer to ultraviolet radiation, and removing the unexposed photoresist. |
