Abstract: A gas detection system that detects gas inside an enclosed space of an aircraft system on board in an aircraft. The system is used in a method for determining the presence of a gas inside an aircraft system by means of a detection system installed on the aircraft system. The system monitors and/or detects a vacuum leak or of fire inside an aircraft system arranged in an aircraft.

Abstract: An aircraft comprising a heat exchanging pack comprising an energy recovering module with a hot and a cold side, the hot side thermally contacting the cold side, providing a heat exchange. The heat exchanging pack also comprises a secondary heat exchanger and a compressor coupled with a turbine. The hot side module inlet fluidly communicates with the bleed air duct, the cold side module inlet fluidly communicates with the ram air duct, the hot side module outlet fluidly communicates with the compressor inlet, the compressor outlet fluidly communicates with the hot side secondary inlet, the hot side secondary outlet fluidly communicates with the turbine inlet, and the cold side secondary inlet fluidly communicates with the ram air duct. The energy recovering module comprises a conversion apparatus, configured to generate energy out from the heat exchange taking place in the energy recovering module between the hot and cold sides.

Abstract: An energy converter for converting kinetic energy from a body of liquid by transverse galloping includes a support, an elongate galloping body extending between a first end and a second end and being of a suitable cross-section for transverse galloping, a substantially horizontal guide arranged outside the body of liquid for guiding the first end of the galloping body, one or more elastic means substantially horizontally arranged and connected between the galloping body and the support, and a generator including a static generator component and a dynamic generator component, and wherein the galloping body is substantially vertically suspended such that the second end of the body extends into the body of liquid, and the dynamic generator component is operationally connected to the galloping body. Further disclosed are energy conversion systems including a plurality of energy converters and methods for energy conversion.

Abstract: The protected resource, typically an API, is exposed by endpoints of a plurality of administrative domains. The endpoints are previously unknown by said service application and the method further comprises: i. using an intermediate or global entity for: a) selecting one of said administrative domains based on flexible criteria (i.e. at least on the identity of said end user but also considering varying user or service preferences); and b) performing, said selected administrative domain, a secure authorization to grant access to said end user by means of an open protocol; and ii. providing, said selected administrative domain to said service application, once performed said secure authorization, direct or proxy access to said user's protected resource via the endpoint established by said intermediate entity.
