Abstract: A flying vehicle propulsion system including a propulsor, a drive system and a heat exchanger. The drive system is arranged to drive the propulsor and the heat exchanger is arranged to thermally regulate at least part of the drive system. The propulsor is arranged to move fluid, thereby producing a propulsor fluid flow having a main direction. The system is arranged such that in a first operation configuration, at least part of the propulsor fluid flow is incident on the heat exchanger, thereby thermally regulating the at least part of the drive system.

Abstract: A first spacecraft comprises a drive mechanism. A second spacecraft comprises a valve for filling/draining the second spacecraft. The coupling assembly comprises a first connector comprising an actuating member configured to engage and open the valve and a coupling member configured to couple to the drive mechanism. A second connector comprises a stop portion and a bore for transferring fluid. Operation of the drive mechanism rotates the coupling member and the second connector together to screw the second connector onto the valve until the stop portion engages the valve, the actuating member being prevented from moving relative to the second connector to open the valve whilst the lock is in the locked state. Once the stop portion engages the valve, operation of the drive mechanism to exert a torque on the coupling member greater than a predetermined torque level moves the lock to an unlocked state wherein the actuating member is moveable relative to the second connector to engage and open the valve.

Abstract: The present disclosure relates to a coupling assembly for fluidly connecting first and second spacecraft. The first space-craft comprises a drive mechanism and the second spacecraft comprising a valve for filling and/or draining the second spacecraft. The coupling assembly comprises first and second connectors and a lock. The first connector comprises an actuating member configured to engage and open the valve and a coupling member configured to couple to the drive mechanism such that the drive mechanism is operable to exert a torque on the coupling member to rotate the coupling member. The second connector comprises a stop portion and a bore for transferring fluid, the second connector configured to screw on to the valve until the stop portion engages the valve.

Abstract: The present disclosure provides new and improved methods for the detection of pathogens, for example viral pathogens, in samples. The methods, tests and assays permit the identification of an infection, for example a Coronavirus infection, in a sample, but can also be used as a means to identify the infectious status or “infectivity level” of a subject. Disclosed is a method for detecting an antigen in a sample, said method comprising: contacting the sample with an antigen binding agent, wherein the antigen binding agent is not an antibody.

Abstract: Disclosed herein are system, method, and computer program product embodiments for establishing communication channels related to assets. An embodiment enables users of home assets such as appliances to share content related to that asset through a centralized clearinghouse of asset content. Aggregated content reduces redundant searches across sources by many users looking for the same content. New data pathways from user to users, manufacturers, and various third parties are established through the connections created in relation to assets.

Abstract: An apparatus for releasing a 3D stereolithographic printed layer from a vat of resin includes a vat having a release layer and configured to contain solidifiable resin; and one or more release mechanisms including a build plate which is configured to adjust the position of the object being printed with respect to a release layer. In order to separate the release layer from solidified resin in contact with the release layer, the apparatus may control the build plate based on a force measurement and/or activate secondary release mechanisms such as vibrating the release layer.

Abstract: The invention relates to recombinant cells and their use in in the production of branched medium-chain alcohols such as 4-methyl-1-pentanol.

Abstract: An air intake duct of an aircraft engine or other component is provided with a thermal anti-icing system. The front of the air intake duct comprises a toroidal outer skin (16) which forms, with a toroidal internal bulkhead (18), a toroidal plenum (8) about the center line (26). The bulkhead has an inner edge nearest the center line. Within the plenum there is a toroidal inner skin (9) defining with the outer skin a substantially continuous toroidal channel (19). Hot air is supplied via an inlet (7) to the plenum (8). The air flows into an inlet (14) at an end of channel (19) and out of an outlet (11) through the bulkhead (18). This provide more heat to the leading edge of the duct, and to the surface of the duct facing the center line, than to other parts of the duct to prevent build up of ice which may enter, and damage, the engine. This reduces the mass flow of hot air needed for de-icing.
