Abstract: A method and a correspondingly configured device detect damage or defects in a support, including at least one tension member, for an elevator system. A pulse generator generates at least one electrical digital input signal that represents at least one first binary number and is fed to the tension member. After the digital input signal has passed through the tension member, it is detected as a digital output signal that likewise represents at least one second binary number. The second binary number is then compared, in particular compared digit by digit or bit by bit, with a setpoint binary number and/or directly with the first binary number. Damage in the tension member is determined on the basis of an issued comparison result. If the second binary number deviates from the setpoint binary number and/or from the first binary number, a fault message is generated.

The detectable element is located between the sensor and the musical instrument. When the musical instrument vibrates, the sensor remains stationary and the detectable element is vibrated relative to the sensor by the musical instrument.

Abstract: A blocking assembly for a leaf of an elevator door includes a translation guide, a first leaf carriage mounted slidably to the translation guide between a first position and a second position, a latch connected to the translation guide and rotatable between a blocking configuration of the first leaf carriage in an intermediate position wherein the latch intercepts and blocks the carriage against the guide, and a configuration for releasing the carriage wherein the carriage is free to slide to the second position, latch return in the blocking configuration, and first coupling connected to the first leaf carriage and to the latch. When the carriage is in the first position, the first coupling is coupled together to keep the latch in the release configuration, in contrast to the action of the return. When the carriage is in the intermediate position, the first coupling is uncoupled so that the latch is moved by the return into the blocking configuration.
