Abstract: The present invention relates to the use of (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4?-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid of formula (I), prefer-ably in form of one of its salts or solvates or hydrates, preferably (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4?-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid in form of monohydrate (I) of formula (I-M-I) or (5S)-{[2-(4-carboxyphenyl)ethyl][2-(2-{[3-chloro-4?-(trifluoromethyl)biphenyl-4-yl]methoxy}phenyl)-ethyl]-amino}-5,6,7,8-tetrahydroquinoline-2-carboxylic acid inform of mono hydrate (II) of formula (I-M-II), in the inhalative treatment of cardiopulmonary and pulmonary disorders, such as pulmonary arterial hypertension (P AH), chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary hypertension (PH) associated with chronic lung disease (PH group 3) such as pulmonary hypertension in chronic obstructive pulmo

Abstract: A method tests a switching state of a circuit breaker device (10) for establishing/breaking a connection of two circuit areas (12, 14), especially in a vehicle. The circuit breaker device includes at least one MOSFET switching element (20) with a source terminal (22) connected with one of the circuit areas (12, 14) and a drain terminal (24) connected with another of the circuit areas (12, 14). A gate driver (26) is associated with the switching element (20) for switching into a connection switching state. The method includes applying a testing voltage pulse to the drain terminal, detecting a voltage drop between the drain terminal and the source terminal, comparing the voltage drop detected with a voltage reference or/and with a time reference, and determining, based on the comparison, an actual switching state of the at least one MOSFET switching element (20) being subjected to the switching state test.
