    摘要: A system for infrasonic pressure fluctuation (infrasound) control of a structure defining an interior. The system includes a reversible compressor including a housing defining an interior opening interface open to the interior of the structure and an exterior opening interface open to an exterior of the structure, and including at least one controllable element to generate positive pressure flows and negative pressure flows between the interior opening interface and the exterior opening interface. The system includes a first pressure sensor located to sense pressure indicative of the interior of the structure, a second pressure sensor located to sense pressure indicative of the exterior of the structure, and at least one controller configured to control the at least one controllable element of the compressor to cancel pressure oscillations within the interior of the structure based on the pressures detected by the first pressure sensor and the second pressure sensor.

    摘要: The invention relates to a method and an assembly for absorbing energy during an overload event using an energy absorber (2) in order to reduce loads on an object (103) being transported on a loading unit (100). The energy absorber (2) is suitable for absorbing energy during a single overload event, which introduces such a high degree of energy that there is an overwhelming likelihood the object would be damaged without an energy absorber, in order to reduce the resulting load on the object during the overload event by means of the energy absorption of the energy absorber (2). Measurement values (62) on the current state of the loading unit (100) are detected using a sensor device (61), and the energy absorber (2) is controlled. A control device (48) detects an overload event (63) from the detected measurement values (62), and a damping of the energy absorber (2) is set to a high value after the detection of the overload event (63). The damping is maintained for a specified prolonged time period (67). The damping is then controlled dependent on the measurement values (62) detected during the overload event in order to increase the load for objects (103) transported on the loading unit (100) during the specified time period (67) initially to a specified threshold load (64) and to control the load after the specified time period (67) dependent on the measurement values (62) detected during the overload event.
