Abstract: The invention provides a display interface in a social networking system that enables the presentation of information related to a user in a timeline or map view. The system accesses information about a user of a social networking system, including both data about the user and social network activities related to the user. The system then selects one or more of these pieces of data and/or activities from a certain time period and gathers them into timeline units based on their relatedness and their relevance to users. These timeline units are ranked by relevance to the user, and are used to generate a timeline or map view for the user containing visual representations of the timeline units organized by location or time. The timeline or map view is then provided to other users of the social networking system that wish to view information about the user.

Abstract: A composer interface provided by a social networking system allows a user to provide input, such as text data, to the social networking system. The composer interface allows the user to identify an action and/or an object related to the input. An action is structured data describing a relationship between objects defined by the social networking system. Based on the action identified as related to the input, the social networking system stores an association between the received input and the identified action.

Abstract: A social networking system presents questions to a user on an interface associated with the social networking system to elicit information about the user that is missing from the user's profile or is otherwise outdated. The questions are selected based on a number of factors, such as the need for or value of the information item, probability of a response, or cost of collecting the information item. In presenting the selected question, the social networking system prompts a user for information about the user in a an interface associated with a page from the social networking system, an application external to the social networking system, or using a push notification or prompt. The questions may be formatted in various ways, such as an explicit question, confirmation, a selection of responses, or social context to encourage the user to respond to the question.

Abstract: A social networking system enables a third party application to request user data based on action types and aggregations of a user's data corresponding to an action type with respect to multiple objects. Users of the social networking system may provide privacy or accessibility of their information based on the action type associated with the information (e.g., a user may allow a particular application to access all actions of a certain type, regardless of the source of those actions). The third party application may use this accessed information to generate personalized content for a user based on aggregations of the user's data and then publish the personalized content back to the social networking system.

Abstract: A fuel injector assembly comprising an injector body having a leading end, a fuel inlet passage, a backleak passage and a trailing end that terminates in an end surface; a cap that fits over the trailing end of the injector body to define therebetween a chamber for receiving fuel from said backleak passage; and a seal for sealing said chamber to prevent the flow of fuel therefrom, wherein said seal is disposed between said end surface of the trailing end and an inlet end of said fuel inlet passage.

Abstract: A fuel injection system for an internal combustion engine comprises a plurality of pumps arranged to supply respective flows of pressurized fuel to a common accumulator volume that supplies the pressurized fuel in turn to a plurality of fuel injectors. An engine control unit controls the flow rate of pressurized fuel into the accumulator volume in response to engine load. The flow rate of pressurized fuel from at least one pump of the plurality is dependent upon engine speed; whereas at least one other pump of the plurality comprises a fuel output control responsive to the engine control unit enabling the flow rate of pressurized fuel from that pump to be varied independently of engine speed. In this way, the engine control unit controls the aggregate flow rate of pressurized fuel from the pumps into the accumulator volume, while controlling only one of the pumps. This reduces the cost of control apparatus and allows greater freedom of pump selection and flow circuit design.
