Abstract: An elevator safety system comprises a plurality of door safety units, each door safety unit; a communication bus connecting the plurality of door safety units; a control unit connected to the communication bus for allowing communication between the plurality of door safety units and the control unit; and at least one position sensor configured for providing information about the current position of an elevator car within a hoistway. Each door safety unit is assigned to an elevator hoistway door and configured for monitoring a condition of the assigned elevator hoistway door. The control unit is configured for polling door safety units included in a subset S1, S2) of the door safety units which are located within a predetermined distance (D1, D2) from the current position of the elevator car.

Abstract: An electronic safety actuator for an elevator safety brake, includes: a solenoid; a permanent magnet, movable by the solenoid between a first position proximate to the solenoid and a second position distal from the solenoid; and a measurement circuit arranged to measure the inductance of the solenoid and thereby detect the position of the permanent magnet. The inductance of the solenoid is dependent on the magnetic field in which it is situated, which is in turn affected by the permanent magnet. Thus, as the proximity of the permanent magnet to the solenoid changes, the inductance of the solenoid changes (increases or decreases). The change in inductance that occurs in the solenoid of an elevator safety actuator is significant enough to be measurable electronically and this measurement can be used to determine the position of the permanent magnet and thus of the safety actuator.
