Abstract: A system for detecting a presence of a person in a hoistway, having: one or more controllers configured to authenticate the person in the hoistway; the one or more controllers being operationally connected to an elevator car in the hoistway and configured to determine whether the person is within a predetermined distance of the elevator car from a signal emitter on the person; wherein when the person is within the predetermined distance of the elevator car, the one or more controllers is configured to transmit a feedback request to the person and stop the elevator car unless the one or more controllers receives feedback to the feedback request within a predetermined period of time.

Abstract: Elevator car ceiling access systems are provided. The elevator car ceiling access systems include an elevator car having a top and at least one elevator car door, an access panel located in a top of the elevator car, a car door operator, an access panel operator, and a selectively engageable coupling arranged between the car door operator and the access panel operator and arranged to selectively couple to the car door operator and the access panel operator to enable selective opening of the access panel.

Abstract: Methods and systems are described herein for predictive adjusted bidding for electronic advertisements. A bid determination computing device receives, from an ad exchange computing device, a bid request for an available underlying impression opportunity. The bid determination device determines an opportunity value estimate for the impression opportunity based upon the bid request, and determines a probability of a submission of one or more other bid requests for the same impression opportunity by the same ad exchange device or by one or more other ad exchange devices. When the determined probability indicates a submission of one or more other bid requests for the same impression opportunity, the bid determination device adjusts the opportunity value estimate for the impression opportunity based upon the determined probability and transmits the opportunity value estimate to the ad exchange device in response to the bid request.

Abstract: Elevator systems and operating methods including an elevator operating panel having at least one button and an audio orientation system. The audio orientation system includes at least one speaker positioned proximate the elevator operating panel and a proximity sensor associated with an associated button and positioned proximate thereto, the proximity sensor arranged to generate a button detection zone around the associated button and detect a presence within the button detection zone. When a detection is made by the proximity sensor regarding a presence with the button detection zone, the audio system controls the at least one speaker to generate an audio orientation signal comprising button information that is related to the associated button within the button detection zone.

Abstract: Elevator systems having an elevator car having a first elevator car door and an audio orientation system. The audio orientation system includes an audio system controller, at least one first speaker positioned proximate the first elevator car door, and at least one second speaker positioned in the elevator car opposite the first elevator car door. When the first elevator car door opens, the audio system controller controls the at least one first speaker and the at least one second speaker such that an audio orientation output is generated at at least one of the speakers to indicate that the first elevator car door is open.

Abstract: Elevator maintenance access systems and methods are provided. The elevator maintenance access systems include a frame defining a structural frame of an elevator car and a moveable element moveably coupled to the frame, wherein the moveable element is moveable relative to the frame between a first state and a second state, wherein when the moveable element is in the second state a maintenance gap is formed to enable access from an interior of the elevator car to an exterior of the elevator car.
