A low-maintenance scrubber inlet device is provided for delivering effluent gases to gas scrubbers. Additionally, systems, methods and devices are provided for forming a respiratory-gated point cloud of a patient’s respiratory system and for placing a localization element in an organ of a patient. The data transmission is effected sequentially in this case. As new present velocities and new present positions are obtained, these steps are repeated until the seek operation transitions from the deceleration phase to a settle phase. Finally, the table comprises foldable legs that support the table. The fastener is adapted to engage a device at the ceiling to mount the arm to the device.
