Abstract:
A pumping system comprising a membrane pump (1) for pumping a medium into or out of a vessel (6), the membrane pump comprising an actuating member (13) for moving a membrane (3) in a first direction from a first end position to a second end position against the action of a spring (12), the membrane being movable in the opposite direction from the second end position to the first end position under the action of the spring. The pumping system comprises sensing means (14) for generating a measuring value representing the location of said first end position of the membrane (3), and processing means (17) for establishing a pressure value representing the pressure inside a vessel (6) connected to an inlet (5) or outlet (24) of a pump chamber (4), the processing means (17) being adapted to establish said pressure value based on said measuring value.

Abstract:
An electromagnetic driven membrane pump has a pump housing inside which at least one pump chamber (15) having at least one intake and outlet is formed and delimited between a gable (1) of the pump housing and at least one completely-sealed membrane (14) attached to a wall (4) of the pump housing and, in an axial direction of the pump housing, to a running axle (13) suspended in at least two separated suspensions in a longitudinal direction of the axle (13). At least one of the suspensions is composed of a flat spring (9) attached to the axle (13) in a radial direction out toward the wall (4) of the pump housing. The axle (13) is composed of magnetic material to be driven by a magnetic field from an electromagnet (7) for oscillation in its longitudinal direction and moving the membrane (14) in corresponding oscillating movement. The flat spring (9) is composed of an inner and at least one outer part, with the inner part attached to the axle (13) and the outer part(s) attached to the pump housing. These parts are connected with one another by two elastic legs, arranged at each side of the point where the spring is attached to the axle (13).
Abstract:
A stripped-down version of a library is generated from server source code extracted from a server project under development. Information extracted from the server source code may include only that information which is exposed to a client project under development. The stripped-down library generated from the extracted server source code is received by a reflection-based component that uses reflection to generate documentation and disclosure information helpful in the development of the client source code. Because the server project does not have to be compiled or ready to be compiled before the software development information for the client project can be provided, development of the server side source code and the client side source code can proceed in tandem or incrementally.
Abstract:
A stripped-down version of a library is generated from server source code extracted from a server project. The transitive closure of program entities extracted from the server source code and referenced by the extracted program entities can be computed. A placeholder entity can be inferred for an entity defined by the transitive closure computation if a definition of the entity cannot be found in the server source code. The stripped-down library generated from the extracted server source code is received by a reflection-based component that uses reflection to generate documentation and disclosure information helpful in the development of the client source code. A placeholder entity can be marked or decorated to signal to the reflection-based component that client source code is not to be generated for the decorated entities.

Abstract:
A fluid sensor is provided which contains a fluid cell (1) to enclose a volume of fluid (7), i.e., a gas or liquid, to be analyzed, in addition to a method for producing such a fluid sensor. An electromagnetic energy source (3) is arranged to transmit electromagnetic waves (4) into the fluid cell (1) with at least one detector (5) arranged to detect electromagnetic waves passing through the fluid cell (1) and at least one opening (2) situated for inlet or outlet of the fluid (7) to be analyzed. A circuit board (8, 10, 11, 12, 13, 14, 15, 16) is arranged to evaluate intensity of electromagnetic waves reaching the detector (5) and/or provide circuitry for the electromagnetic energy source (3). At least part of the fluid cell (1) is incorporated into the substrate of the circuit board (8, 10, 11, 12, 13, 14, 15, 16).
