Abstract: A flying vehicle propulsion system comprises a propulsor, a drive system, a heat exchanger, and a housing in which the heat exchanger is provided. The propulsor produces a propulsor fluid flow. In a first operation configuration of the propulsion system, at least part of the propulsor fluid flow is incident on the exchanger. A propulsor fluid flow inlet port of the housing fluidly communicates with a chamber of the housing on an inlet side of the exchanger. The inlet port receives the propulsor fluid flow for ingestion into the chamber and exchanger and comprises a valve to close the port when the valve is closed and open the port when the valve is open. The valve is biased such that at least one of: the valve opens passively under a propulsor fluid flow rate influence above a pre-defined threshold impinging on the valve; and the valve closes passively under a biasing influence.

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.

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 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.

Abstract: A vertical manure converter and related process of using activated carbon in an activated carbon/organic material mixture to process organic waste. Inducing air, preferably compressed, into a chamber of the converter in combination with reusing activated carbon can result in a continuous process. The temperature can be controlled by regulating the air into the chamber. The vertical manure converter takes organic waste and uses heat to accelerate the composting process wherein final products can be purified water and ash fertilizer.
