Abstract: A diffuser element for the underside of a vehicle comprises in longitudinal vertical section, in sequence from front to rear, a first smoothly and monotonically rising panel, and a second panel, and a gap between the first and second panels, wherein the edge of the second panel adjacent the gap comprises a substantially flat planar section which is offset from and below the plane of the first panel ahead of the gap. This type of gap in the diffuser serves to bleed off the boundary layer from the airflow passing through the diffuser, thus enhancing its effectiveness and improving the downforce that is generated as a result. The gap is preferably located in the front half of the diffuser and can form the entrance to a duct leading to an exit on the rear of the vehicle.

Abstract: A motor vehicle having an outer bodywork surface including front and rear wheel arches and at least one passenger or driver door on each side of the vehicle, in which a luggage compartment is provided on at least one side of the vehicle, each luggage compartment being located within the outer surface and forwardly of the rear wheel arch, the luggage compartment having an opening which extends at least partially over the top of the luggage compartment and which is closable with a hinged panel, the panel forming part of the outer bodywork surface of the vehicle and having a hinge which is located behind the rear of the luggage compartment and towards the rear of the vehicle.

Abstract: The systems and methods described herein relate to providing review content which is verifiable in a public blockchain network. The system receives an identity verification for a user of a review engine, then assigns a unique pseudonymous identity to the user based on the identity verification. Next, the system receives an identity verification for a provider on the review engine, and generates an authentication token unique to the provider to be displayed on a user client device associated with the user of the review engine. In response to the user capturing the authentication token via the client device, the system generates a review-in-progress to be displayed on the client device. Upon receiving a completed review from the user, the system records hashed data associated with the review into a transaction record on a public blockchain network, such that the transaction record can be publicly audited on the public blockchain network.

Abstract: A vehicle has external bodywork including an upper surface and an under surface, the under surface having at least one aperture, and the vehicle comprising lower ducting located within the external bodywork and communicating with that aperture, the upper surface having at least one aperture, and the vehicle comprising upper ducting located within the external bodywork and communicating with that aperture, the upper ducting and the lower ducting leading to a fan adapted to selectively draw air through the respective ductings, the vehicle further comprising a control unit adapted to receive information as to the vehicle dynamic state and, in the light of that state, draw air through the lower ducting or through the upper ducting. Thus, a choice can be made between enhanced levels of downforce on the one hand, and low drag on the other.

Abstract: The invention described herein pertains to a housing for a vertical-axis wind turbine, a vertical-axis wind turbine, and an apparatus comprising a housing and a vertical-axis wind turbine. For example, the disclosure below provides more efficient electricity generation from a vertical-axis wind turbine assembly. Increases in efficiency may be achieved by the housing through novel angled louvres and integrally housed electrical stators. Increases in efficiency may also be achieved through a magnetic spindle bearing and Savonius blade geometry. The turbine may be sized and configured for attachment to existing structures.

Abstract: The systems and methods described herein relate to providing verification of user identities within a review engine via authentication non-fungible tokens (“aNFTs”). The system receives an identity verification for a user of a review engine, then assigns a unique pseudonymous identity to the user. The system receives an identity verification for a provider on the review engine. The system then generates an aNFT that is unique to the provider. The aNFT includes one or more value attributes which correspond to at least authenticating the user within the review engine. Next, the system generates a review-in-progress to be displayed on the user client device. The system then receives a completed review from the user client device, and records hashed data associated with the completed review into a transaction record on a public blockchain network, such that the transaction record can be publicly audited on the public blockchain network.

Abstract: We disclose a chassis for a vehicle, comprising an interconnected framework comprising a plurality of tubular sections, and at least one sheet bonded to the framework, wherein the tubular sections are of a non-ferrous metallic composition. The non-ferrous tubular sections have a very thin wall; generally, these sections are made by extrusion, which currently allows for wall thicknesses no thinner than about 2.5 mm. We prefer the wall thickness to be about this level, and ideally no greater than 3 mm. Such a thin-walled tube would usually imply a lower resistance to buckling, but as part of the structural element defined above, we have found that the tube does not buckle and in fact has an impact response that is superior to other alternatives. We therefore prefer that the tubular sections have a profile for which the ratio of the minimum area moment of inertia of its cross section to the square of the unsupported length of the section is less than 2 mm2.

Abstract: A chassis and a method of forming the chassis comprising assembling a framework of interconnected tubular-section metallic members and a plurality of composite panels, each panel being adhesively bonded to a plurality of the metallic members, wherein at least one bond between a composite panel and a metallic member is formed by an arcuate formation integral with and extending from an edge of a planar section of the composite panel and fitting around an exterior of the metallic member, and providing a layer of adhesive along the gap there between extending substantially from the edge of the planar section across a part of but less than the complete angular extent of the arcuate section.

Abstract: An offshore reservoir monitoring system (100) comprises a vertical array (110) with multiple seismic receivers (120) less than 10 m apart. During operation, the vertical array is deployed in a shallow borehole (111) in a seabed (10) away from noise at a seafloor (11). The dense spacing of receivers (120) ensures an adequate number of sensors (120) in the shallow borehole (111) and a spatial sampling rate appropriate for suppressing coherent noise in the shallow layers under the seafloor (11). Vertical arrays (110) can be added to the system (100) at any time.

Abstract: A vehicle with a load space to provide a chassis comprising a framework (10) comprising a pair of spaced-apart elongate longitudinal members (12, 14) connected by a pair of spaced-apart elongate lateral members (20, 22) and bracing for the thus-defined framework, a rear suspension attached to the rearmost lateral member (20) and comprising a trailing-arm arrangement (52), and a front suspension attached to the front most lateral member (22) and comprising a leading-arm arrangement (58). This creates a rigid core for the chassis, which also provides all four suspension mounting points.

Abstract: We improve still further the crashworthiness of a tubular-frame chassis by providing a means for absorbing lower-energy impacts without deforming the tubular steel frame, The vehicle comprises a chassis structure including a load-bearing tubular chassis member extending longitudinally within the vehicle, at least one crush structure located laterally outside of the chassis member, the crush structure having an upper and a lower extent that overlap with an upper and lower extent of the chassis member. In this way, the crush structure is able to interact with the chassis member, transferring impact forces to the chassis member and thereby reducing the necessary size (and weight) of the crush structure. The crush structure is preferably removable, to allow replacement after an impact. Alternatively, the crush structure part of a door of the vehicle, positioned as necessary when the door is closed.
