Abstract: A nebuliser comprises an outlet aperture and a liquid capillary. A method of operating the nebuliser comprises supplying a gas to the outlet aperture, measuring a flow rate of the gas supplied to the outlet aperture, and determining a position of the liquid capillary relative to the outlet aperture based on the measured flow rate.

Abstract: A current detection device for measuring current flowing through a conductor having a magnetic core having a channel for receiving the conductor therethrough, and a magnetic field transducer positioned at least partially within an air gap of the magnetic core. The magnetic field transducer is configured to respond to the presence of a magnetic field by generating an output electrical signal based on a flux density of the magnetic field. The magnetic core comprises an absolute saturation flux density that is substantially lower than an absolute saturation flux density of the magnetic field transducer. Accordingly, a response of the current detection device within the magnetic flux density operating range varies in sensitivity and is substantially non-linear. The response of the current detection device is preconfigured. The current detection device may be implemented in devices and systems where a substantially wide sensing range and relatively high, low-current sensitivity is desired.

Abstract: A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

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: 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 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: 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.

Abstract: A kit for constructing a commercial vehicle supplied ex-works as a flat-pack package using the vehicle chassis as a pallet. The kit includes components comprising: a chassis, an engine attachable to the chassis, located within and supported by the chassis, and a plurality of upright chassis members attachable to the chassis thereby to define at least a cabin, placed flat over the chassis. The component making up the kit can be restrained in place, such as by wrapping or tying with suitable film, bands or cords. Body panels attachable to the chassis uprights can be supplied, placed flat over the chassis. Brake line, a wiring loom and major drivetrain items such as the engine, differential and propshaft may be pre-attached to the chassis in their final locations before shipping the kit. With suitable spacers, several such kits could be packed for transport in a single vehicle or container.
