An assembly () for controlling movement of an automatically moveable door panel () includes a sensor () positioned on at least one of a door panel () or a door frame member (). The sensitive portion provides an indication of when an object is in contact with or in very close proximity to a sensitive portion. A sensitive portion is established over an area of the door or door frame member at which an object may become caught during automated door movement. A disclosed example includes using an electromechanical film as a sensor so that the sensitive portion is responsive to pressure applied by the object on the sensitive portion. Another disclosed example includes a field effect sensor that generates an electric field that is at least partially interrupted when an object contacts or comes in very close proximity to the sensitive portion. Automated movement of a door is controlled responsive to an indication of the presence of an object in a location where the object may become caught during automatic movement of the door.

An hydraulic elevator (10) is powered by a pair of jacks (45) disposed adjacent to opposite sides of the platform (40) of the elevator car at medial locations thereon for enhanced compactness of the elevator and generally symmetric, nonbending support of the car.
