Abstract: Content can be delivered to devices via one or more networks based on clusters of attributes in some examples. As one particular example, a server can determine a first set of attributes corresponding to a cookie associated with an entity and determine a second set of attributes corresponding to a mobile advertiser identifier (MAID) associated with the entity. The server can generate a cluster of attributes for the entity based on the first set of attributes and the second set of attributes. The system can then receive audience definition criteria defining a target audience for content and determine whether the cluster of attributes satisfies the audience definition criteria. If the cluster of attributes satisfies the audience definition criteria, the server can designate the cookie and the MAID as belonging to the target audience to enable the content to be delivered to the entity.

Abstract: A fastener system (9) for fastening a first structure to a second structure, the fastener system (9) includes: (i) a bolt (11) having a countersink bolt head (15), a bolt tip (17), and a threaded male portion (19) extending from the countersink bolt head (15) towards the bolt tip (17), (ii) a nut (13) having a countersink nut head (23), a nut tip (25) and a female shank portion (27) extending from the countersink nut head (23) towards the nut tip (25), wherein the female shank portion (27) includes an inner thread (29) configured for co-operating with the threaded male portion (19) of the bolt (11), and (iii) at least one cavity (33, 35) for a locking material, the at least one cavity (33, 35) is formed in the threaded male portion (19) of the bolt (11) and/or the inner thread of the female shank portion (27) of the nut (13).

Abstract: A fastener comprising a shaft having a first end and a second end, the fastener comprising a head at a first end of the shaft, the shaft defining either a radially extending recess between the first and second ends and/or a head with regions having different radii of curvature.

Abstract: A fastener is provided for an aircraft structure, the fastener comprising a shaft and a bugle shaped head, in which the bugle head comprises a first region proximate the shaft, the first region having a first radius of curvature, and, a second region on the opposite side of the first region to the shaft, the second region having a second radius of curvature, in which the second radius of curvature is higher than the first radius of curvature.
