The invention relates to a filter for filtering particles from a plasma plume. The filter includes a housing with two pass-through openings arranged in the housing wall and forming a pass-through channel for passing at least part of the plasma plume through the housing, which pass-through channel extends from one side of the housing to an opposite side of the housing, at least one primary blade arranged at a distance from and rotatable around a rotation axis, which rotation axis is parallel and spaced apart from the center line of the pass-through channel, with the path of the at least one primary blade intersecting with the pass-through channel and with the at least one primary blade having a contact surface for contact with the plasma plume, which contact surface is facing in the direction of the rotation direction, and a drain channel connecting to a drain opening arranged in the housing wall. A line extending perpendicular from both the center line of the pass-through channel and a radial line extending from the rotation axis through the center line of the pass-through channel and through the path of the at least one primary blade, extends through the drain opening.

A sensor system includes a sensor element, a signal processing circuit, and a pseudo-signal correction circuit. The sensor element outputs an electric signal corresponding to an external force. The signal processing circuit converts the electric signal coming from the sensor element into a signal having a certain signal format and then outputs the signal thus converted. The pseudo-signal correction circuit corrects a pseudo-signal outputted by the sensor element. When receiving a test signal, the sensor element performs a self-diagnosis based on the test signal and then outputs the pseudo-signal, which represents a result of the self-diagnosis. The pseudo-signal correction circuit corrects the pseudo-signal based on environment information about an environment where at least one of the sensor element or the signal processing circuit is located.

A two-stage dust-air separation structure includes a cyclone separator and a spiral dust-air separation device. A first stage separation of dust from air is realized by a cyclone housing, and by arranging a second-stage cyclone barrel 5 inside the cyclone housing and arranging the spiral dust-air separation device at a barrel opening of the second-stage cyclone barrel, the dusty air, after going through the first stage separation, is guided by the spiral dust-air separation device to form, on an inner wall of the second-stage cyclone barrel, an airflow rotating towards the barrel bottom, and the dust in the airflow is driven by a centrifugal force to rotate downwardly to the barrel bottom and be collected in a second-stage dust collecting space, and the air in the rotating airflow is extracted by the negative pressure, thereby realizing a second stage separation of dust from air.

This disclosure provides a two-phase separator device for separating condensate or particulate from a gas stream. In some implementations, the separator device removes water from air and may operate under micro-gravity conditions. The gas stream flows through the two-phase separator device and passes through a rotatable vane assembly along a flow path without being redirected in another flow path. Condensate or particulate in the gas stream is impacted by a plurality of vanes of the rotatable vane assembly, and the condensate is captured by features formed within the plurality of vanes. The captured condensate is accelerated radially outwardly along the each of the plurality of vanes towards a sloped inner wall, and further moved along the sloped inner wall in a direction against the flow path of the gas stream during rotation.
