A refuelling connector has an inner pipe section (e.g. defining inner region 138) for conveying cryogenic hydrogen to an aircraft and an outer pipe section (e.g. defining outer region 136) for holding a vacuum to provide thermal insulation to the inner section. Via one or more suitable valves (126, 132) the connector can, when connected to the aircraft, create a vacuum on the aircraft-side or otherwise convey fluid from / to the aircraft, via the outer pipe section (136).

There is provided a firearm (3) with a closed sight (1) mounted thereon. The closed sight is received on top of a mounting pin (7) extending upwardly from the firearm (3). A locking fastener (28) extends through a side of the closed sight (1), in a direction perpendicular to the extension of the mounting pin (7), and a first end of the locking fastener (28) engages the mounting pin (7) to form an interlock, such that the closed sight (1) is securely mounted to the firearm (3).

A tire monitoring device is disclosed, which detects potential hazards, such as debris, nails, and obstructions that could lead to tire damage or failure. The tire monitoring device comprises at least one embedded sensor positioned within the wheel well of a vehicle. The sensors are connected to an internal display panel positioned within a vehicle, such that drivers can receive notifications about issues, such as low tire pressure, punctures, and road debris. In one embodiment, the sensors have a thermoset exterior layer which serves the dual purpose of protecting both the vehicle body and the embedded sensors within.

A motion generation apparatus comprising: a platform (3) for supporting an occupant; a base assembly (5); and three support arms (9a-9c) arranged to support the platform above the base assembly. Each support arm is connected at its lower end to a carrier (13a-13b) via an arm-carrier joint (39), and is connected at its upper end to the platform at an arm-platform joint (29). Each carrier (13a-13b) is moveably mounted on the base assembly (5) such that the carrier (13a-13b) is independently moveable in a first (X) direction and in a second (Y) direction, the first and second directions being mutually perpendicular to one another. For each support arm (9a-9c), the arm-carrier joint (39) may be a revolute joint having a single rotational degree of freedom about a pivot axis, and the arm-platform joint (29) may be a rotational joint having three rotational degrees of freedom. A torsion bar 49 may be arranged to provide a biasing torque to offset the payload of the apparatus.

A helmet system (103, 104, 106) that includes a flexible member assembly (2500, 2501, 2503, 2505) removably attachable to the helmet system is disclosed, for example to a mount (140, 2700, 4100, 4101, 4102, 4103) disposed on an outer surface (117) of a helmet shell (105, 205). The flexible member assembly includes a coupling member (2520, 2540, 2560) attached to an end of a flexible member (2510, 2512). The mount includes an interface (2220, 2230, 2260, 2261) having an assembly portion (2222) for receiving the coupling member and a lock portion (2226, 2236, 2266, 3514) for securing the coupling member. In some implementations, the coupling member may be secured with tactile feedback, seated by tension applied to the flexible member, and/or is flush with an outer surface of the mount when secured. The helmet system may further include a visor mount and a visor assembly configured for adjustable positioning along a rail. A flexible member assembly independently attachable to an object (150, 2800, 4200) associated with a helmet system is also disclosed.

An electropermanent magnet array is provided. The electropermanent magnet array includes one or more of a plurality of electropermanent magnets of common length, arranged in a parallel fashion, and a planar pole piece, coupled to the first ends of the plurality of electropermanent magnets. Each electropermanent magnet includes a first and a second end opposite the first end.

The present disclosure relates to a system (100) for converting biomass to methanol and methods of performing the same. The system (100) comprises a gasification reactor (102), air-separation unit (112), electrolysis unit (114), water-gas shift reactor (124) and methanol synthesis reactor (116). Preferably, the system (100) comprises a bypass conduit (136) for diverting a portion of syngas produced by the gasification reactor (102) so that it does not pass through the water-gas shift reactor (124).

An accessory mounting system is attachable to a helmet. The accessory mounting system is operable for positioning an accessory device, for example a display device, for example a heads-up display (HUD) device, in front of an eye of the user. The accessory mounting system includes an accessory assembly including an accessory device, for example a viewing device. The accessory assembly is attachable to a rail with a safety release mechanism that releases the rail from the rail carrier when greater than a threshold amount of force is applied to the rail. An adjustment frame of the accessory assembly is coupled to the rail and is slidable along the rail to position the accessory device. The adjustment frame includes a locking knob with protrusions that engage with compliant protrusions of the rail to selectively position the adjustment frame along the rail and to maintain the adjustment frame in a selected position.

A pod attachment system for headgear is disclosed. The pod attachment system includes a pod mount that can be coupled to a helmet shell and a pod, for example an electronics pod such as a sensor pod, that can be removably attached to the pod mount. A user can attach a pod to the pod mount and can remove the pod from the sensor pod mount. The pod mount includes a mechanical interface for attaching the pod to the pod mount. The mechanical interface includes one or more guiding features that cooperate with one or more locating features of the sensor pod to aid the user in attaching the pod to the sensor mount. The pod includes a locking component for securing the sensor pod on the pod mount. The pod attachment system may include an electrical interface for electrically coupling the pod to the pod mount for exchange of communication and power signals therebetween.

A helmet attachment system configured to securely mount objects to helmets and accommodate various helmet sizes and configurations. The system includes three adjustable arms, a first side arm, a second side arm, and a bottom arm, that connect to respective helmet interfaces, such as rail and rim interfaces. Each arm incorporates a worm gear adjustment system including a worm rotator, threaded members, retention mechanisms, and adjustment plates with grooves for discrete positioning. This configuration allows for length adjustments of each arm, ensuring a customizable and stable fit. The system also integrates features like spring-loaded bumpers to minimize snagging, modular battery brackets (HBB) for accessory integration, and electrical interfaces for power and data transmission.
