A material processing system (100) comprising a control system (200) and a material element identification marking system (300). The control system (200) is operable to receive a part request instruction (202). In dependence of the part request instruction (202), the control system (200) is operable to: determine a region (208) of a material element (206) which will form the part (204), and control the material element identification marking system (300) to perform a marking operation configured to apply an identifier (302) to the region which will form the part (204).

A safety element for an aircraft actuation system comprising an actuator, an inceptor, and a shear pin connecting the motor to the inceptor is described. The safety element comprises an absorber zone which is configured to deform in response to an excess force event in the aircraft actuation system, and is locatable between the shear pin and the actuator. The safety element reduces a force applied to an element such as the shear pin during the excess force event. Especially, where the excess force event is caused by the actuator, the shear pin is preventable from breaking.

A method 100 is provided for handling flowable materials 208, comprising the steps 102-112 of: aligning a first container 206 with a dispensing means 202; extending a nozzle 204 from the dispensing means 202 at least partially into the first container 206; depositing the flowable material 208 from the nozzle 204; retracting the nozzle 204 while the flowable material 208 is being deposited from the nozzle 204; stopping further deposition of the flowable material 208 and removing the nozzle 204 from the first container 206 when a measured amount of flowable material 208 has been deposited; and sealing the first container 206. Also described herein is a system 200 for handling flowable materials 208.

Method, apparatus and systems are described that are configured to obtain RF signals, wherein the RF signals are transmitted by each of a plurality of RF emitters, process the obtained RF signals using a trained RF emitter profiling model, and group the obtained RF signals into one or more groups, wherein the RF signals within each group are deemed to originate from the same RF emitter.

There is provided a twin rudder arrangement (100) for a craft (250). The twin rudder arrangement (100) comprises a first rudder blade (110) and a second rudder blade (120), wherein the first rudder blade (110) and second rudder blade (120) are configured to be provided at either side of a propeller (200) of the craft (250). The first rudder blade (110) and second rudder blade (120) are rotatable around the propeller (200) about a single common axis. Also provided is an aircraft or watercraft comprising at least one twin rudder arrangement (100).

There is provided a twin rudder arrangement (300) for a craft (250). The twin rudder arrangement (300) comprises a first rudder blade (310) and a second rudder blade (320), wherein the first rudder blade (310) and the second rudder blade (320) are configured to be provided at either side of a propeller (200) of the craft (250). At least part of the first rudder blade (310) or the second rudder blade (320) comprises a vortex generator arrangement (400), wherein the vortex generator arrangement (400) is arranged to induce vortices in fluid flow passing/interacting with the twin rudder arrangement (300). Also provided is an aircraft or watercraft comprising at least one twin rudder arrangement (300).

Methods, apparatus and systems are described configured to: obtain RF data at a remote node of a system, wherein the RF data is transmitted by a RF emitter; process the obtained RF data at the remote node using a trained RF emitter profiling model to perform feature extraction; determine whether the respective RF emitter is a known emitter; provide data relating to the RF emitter to a central node of the system in the event that the RF emitter is not a known emitter; and provide data relating to the RF emitter to a local database at the remote node in the event that the RF emitter is a known emitter.

A computer-implemented method is disclosed, in which a Large Language Model, LLM, is used to score or rank a plurality of test cases for use in fuzz testing an autonomous system. The method comprises: receiving a definition of interestingness and a plurality of test cases; providing the definition of interestingness and the plurality of test cases to the LLM in the form of first input text and second input text, respectively; and receiving an output from the LLM. The output is indicative of a respective score or ranking assigned to each one of the plurality of test cases by the LLM in accordance with the definition of interestingness. The autonomous system may then be fuzz tested by selecting one or more of the plurality of test cases in accordance with the assigned scores or rankings, and executing the selected test case(s) by the autonomous system.

A vehicle (100) comprising a chassis (200), a chassis suspension system (400) configured to support the chassis (200) relative to a substrate (500) and a control system (600). The control system (600) is operable to: receive a command to achieve a first objective and determine a first chassis suspension system configuration required to achieve the first objective. The first chassis suspension system configuration is defined by a relative orientation of each of the wheel arms (402) relative to the chassis (200) and a relative orientation of each drive wheel mounting member (416) relative to its respective wheel arm (402). The control system (600) is operable to operate one or more of the wheel arm actuators (430) and drive wheel mounting member actuators (440) to achieve the first chassis suspension system configuration.

A landing craft (10) comprising a hull (100). The hull (100) extends along an x-axis, a first end (102) of the hull (100) and a second end (104) of the hull (100) spaced apart from one another along the x-axis. The hull (100) extends along a y-axis, a first side (106) of the hull (100) and a second side (108) of the hull (100) spaced apart from one another along the y-axis. The hull extends along a z-axis, a base side (110) and a top side (112) of the hull (100) spaced apart from one another along the z-axis. The landing craft (10) further comprises a gyroscopic boat stabiliser (600) fixed to the hull (100) and configured to: sense a change in the landing craft orientation; and apply a force to the hull in response to the change in the landing craft orientation.
