Abstract: An illustrative example embodiment of an elevator rope sway damping assembly includes a plurality of sway dampers having a width and a length. An actuator device selectively causes movement of the sway dampers in a direction transverse to the length between a first position where the sway dampers are spaced apart by a first distance and a second, sway-damping position where the sway dampers are spaced apart by a second, shorter distance. The actuator device provides an indication when the sway dampers are in the first position.

Abstract: An electronic safety actuator (1) for an elevator safety brake, includes a first solenoid (2), a magnet (3), movable by the first solenoid (2) between a first position proximate to the first solenoid (2) and a second position distal from the first solenoid (2) a second solenoid (6) and a detector (8). The detector (8) is arranged to apply an electrical signal to one of the first solenoid (2) and the second solenoid (6), and to detect an electrical signal induced in the other of the first solenoid (2) and the second solenoid (6) as a result of the applied electrical signal. There is also provided a method of detecting a condition or state of the first solenoid (2) or the magnet (3).

Abstract: A linear propulsion machine and system (10) is disclosed that includes a stator (30) having a plurality of teeth (34) and a mover (32) moveable in a linear direction along the stator (30). The mover may include a plurality of spaced apart ferromagnetic strata (40), a plurality of slots (42), a plurality of wire coils (44), and a plurality of magnet layers (46). Each of the slots (42) may be adjacent to at least one of the strata (40). Each coil (44) may be disposed in a slot (42). Each magnet layer (46) may be sandwiched between strata (40) and disposed inside one of the plurality of coils (44). Each coil (44) is disposed perpendicularly to the direction of magnetic flux of the magnet layer (46) around which the coil (44) is wound. In an embodiment, the teeth (34) or the magnet layer (46) may be disposed at an angle.

Abstract: Provided are embodiments for identifying waiting passengers outside an elevator using deep learning and machine learning and automatically supporting social distancing for elevator passengers. Embodiments include receiving a call request from an elevator floor; capturing an image of the elevator floor registering the call request responsive to receiving the call request; and determining, from the image, a presence of one or more waiting passengers on the elevator floor registering the call request. Embodiments also include dispatching an elevator car to the elevator floor registering the call request; and controlling the elevator car based at least in part on determining the presence of the one or more waiting passengers.
