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.

Abstract: A valve assembly including an actuator and a valve, the valve including a valve body having first and second ports and a valve seat between the first and second ports, a valve member carried on a valve stem and the valve stem being moveable to move the valve member at least one of into or out of engagement with the valve seat to prevent or permit communication between the first and second ports and wherein the actuator includes a stepper motor the rotational movement of which is converted to linear movement of the valve stem by a transmission, the transmission being adapted to maintain the valve stem in a position to which it is moved by the operation of the actuator whereby the transmission means is a non back-derivable transmission.

Abstract: A method of controlling a fluid in a life support system including at least one of a G-suit and a counterpressure garment including utilizing a control system comprising a control valve having a moveable part which is moved by an actuator in response to an input to the control system to operate the valve to bring a parameter of the fluid towards a desired value, the input being conditioned to provide a control signal to cause the actuator to move the moveable part of the valve and wherein the method comprises conditioning the input by comparing the input with reference information relating to the position of the moveable part of the valve, and when the comparison indicates that the position of the moveable part of the valve is not at a desired position, issuing the control signal incrementally to move the moveable part and updating the reference information so that the updated reference information is available for future comparison with the input.
