Abstract: A computer-implemented method of simulating a mass filter, which has a bandpass characteristic, of a mass spectrometer includes: receiving a first candidate magnetic field strength and a first candidate electric field strength of the mass filter; based on the received first candidate magnetic and electric field strengths, determining a corresponding centre mass of the mass filter; based on the received first candidate magnetic and electric field strengths, determining the width of a passband of the bandpass characteristic; and determining at least one of a lower or an upper bound of the passband of the bandpass characteristic of the mass filter, the determining of the upper bound including adding a first predetermined fraction of the determined width of the passband to the determined centre mass and the determining of the lower bound comprising subtracting a second predetermined fraction of the determined width of the passband from the determined centre mass.

Abstract: An air pipe for an intake tract of an internal combustion engine may include at least one air channel for guiding a through-flow of air to at least one compressor arranged downstream thereof. An air guiding device may be arranged to influence a forward flow of air running in a direction towards the at least one compressor and facilitate reducing turbulences of the air flow.

Abstract: The invention concerns an elastomer hose to connect to a nozzle, wherein the elastomer hose comprises a circumferential edge at least at a longitudinal end. In one exemplary approach a support structure protrudes from a first circumferential section of the circumferential edge and by which the longitudinal end of the elastomer hose is connectable in a positively form-locking manner to a complementary counter-support structure on the nozzle. Additionally, a grip structure protruding from the circumferential edge in a second circumferential section, which is offset from the first circumferential section in a circumferential direction, at which the longitudinal end, is manually grippable when connecting the elastomer hose to the nozzle axially pullable up on to the nozzle.
