Abstract: According to a first aspect disclosed herein there is provide a device comprising: a PUF module, and one or more outer layer components providing at least part of an unsecured channel for inputting a challenge to the PUF module and receiving back a response. Internal logic of the PUF module comprises a logging mechanism arranged to automatically log a record of the challenge and/or response in a log medium, e.g. a blockchain. According to a second aspect, there is provided a method comprising: sending a first message to be recorded on a blockchain, submitting a query to check that the first message has been recorded on the blockchain without manipulation, on condition thereof, sending a second messaging transaction to be recorded on the blockchain. The first and second aspects may be used together or independently.

Abstract: An image processing apparatus comprises processing circuitry configured to: obtain a respective identity and location for each of a first plurality of landmarks in a reference volume; obtain a respective weighting for each landmark of the first plurality of landmarks; obtain a respective identity and location for each of a second plurality of landmarks in a further volume; and determine a transform based on a fit between the first plurality of landmarks and the second plurality of landmarks, wherein the fit is determined in dependence on the weightings.

Abstract: A method of managing resources of a network comprising a profile mapping step and an orchestration step. The profile mapping step comprises assigning a profile to an end user device, and the orchestration step comprising using the profile to apply rules to network elements to manage resources of the network available to the end user device.

Abstract: A hockey goal frame and a hockey goal frame with a mesh net assembly are disclosed. The hockey goal frame includes two vertical posts joined by a crossbar that defines a forward frame. The forward frame is supported by a lower supporting member. The forward frame and lower supporting member have attachments wires for accepting an attachment tab from a mesh net in order to attach the mesh net to the frame. The attachment tabs have two complimentary hook-and-loop fasteners that are coupled to surround the attachment tab around the attachment wires.

Abstract: A process for producing composite structures having a core between resin-impregnated composite layers, and composite structures formed by such a process. The process uses non-impregnated fabric layers and a core layer placed on a mold such that the core layer is between at least two fabric layers, a first of which is disposed between the mold surface and a first surface of the core layer, and a second of which is disposed at a second surface of the core layer. The second fabric layer is then infused with a resin, which flows through holes in the core layer into the first fabric layer, such that the first and second fabric layers are uniformly impregnated with the resin and the core layer is not. The resin is then cured to cause the impregnated first and second fabric layers to bond to the core layer.

Abstract: A system, method, and information processing system manage policy rules. A first unique identifier (121) associated with a first policy rule (120) is compared to at least a second unique identifier (130) associated with a second policy rule (202) in a set of policy rules (128). The first policy rule (120) and each policy rule in the set of policy rules (128) are associated with at least one common characteristic. The set of policy rules (128) are updated to include the policy rule (120) in response to the first unique identifier (121) failing to substantially match the at least second unique identifier (130). A notification (422) indicating a potential policy rule conflict exits between the policy rule (120) and the set of policy rules (128) is generated in response to the first unique identifier (121) substantially matching the at least second unique identifier (130).

Abstract: A vehicle includes a high assurance processing system including a plurality of data processors coupled in parallel, a bridge coupled to the input/output processor, and an input/output processor coupled to the bridge for coupling to a sensor and an effector. Sensor data passes to the bridge through the input/output processor for processing by the parallel data processors, which generate redundant effector data for comparison by the bridge to detect errors. If data matches are found, data is transmitted to the effector.
