  • Patent number: 9547293
    Abstract: A control system and method for controlling electromagnetic drive pumps as, for example, electromagnetic driven membrane pumps are provided in which the control system is formed by at least one microprocessor and at least one sensor, whose microprocessor controls the power supply to at least one electromagnet whose changes in emitted magnetic field causes at least one moving part, directly or indirectly, to perform an oscillating pumping movement. The control system includes at least one positioning sensor which senses the moving part's position in the electromagnetic driven pump. By using the positioning sensor's measurements, the pump can be controlled with great accuracy.

  • Patent number: 8845306
    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.

  • Patent number: 8708665
    Abstract: A membrane pump (1) for pumping a medium has a pump housing (2), a membrane (3) mounted to the pump housing and delimiting a pump chamber (4) inside the pump housing (2) and an actuating device for moving the membrane (3) to and fro to expand and contract the pump chamber (4). In a first operating mode, the actuating device moves the membrane (3) in a frequency suitable for pumping the medium into and out of the pump chamber (4), and in a second operating mode, the actuating device moves the membrane (3) in a frequency in the audible frequency region.

  • Patent number: 8407667
    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.

  • Patent number: 8272850
    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.

  • Patent number: 8239823
    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.
