Acquisition of position information of an elevator car. The system for acquiring the position information of an elevator car of the invention comprises: a first Bluetooth module travelling in an up-down direction of an elevator hoistway following the elevator car, and a second Bluetooth module disposed in the elevator hoistway; wherein the second Bluetooth module broadcasts a Bluetooth signal containing an identifier of the second Bluetooth module to the elevator hoistway, and the first Bluetooth module senses signal strength information of the Bluetooth signal it receives and determines the identifier corresponding to the second Bluetooth module broadcasting the received Bluetooth signal; the system is configured to determine the position information of the elevator car according to received signal strength information of the Bluetooth signal and a corresponding identifier.

A stabilizing system may be utilized to reduce or eliminate sway of magnetic tape that is suspended in an elevator hoistway and provides a positional reference to an elevator cab. The stabilizing system may include a stabilizing mechanism fixed within a hoistway and a roller cam disposed on the elevator cab. The stabilizing system may include a telescoping member attached to a guide having opposing flanges that restrict movement of the tape. The telescoping member and the guide may be biased in an extended position, where the guide partially surrounds the tape. In a retracted position, the guide is horizontally spaced apart from the tape. When the elevator cab passes the stabilizing mechanism, the roller cam may force the guide and the telescoping member into the retracted position to prevent any contact between the stabilizing mechanism and components disposed on the elevator cab.

A component monitoring system for monitoring a component of a conveyance system including a conveyance apparatus including: a camera configured to capture a sequence images of the component, the sequence of images being motion data; and a processor configured to determine an evaluation summary of the component in response to at least the motion data.

An elevator system includes a car door and a sensor module. The car door is movable relative to an elevator car by a drive mechanism. The sensor module includes a first acoustic sensor arranged to provide a first acoustic signal, a second acoustic sensor arranged to provide a second acoustic signal, and a processor arranged to receive the first acoustic signal and the second acoustic signal. The processor is programmed to, responsive to an input provided to the first acoustic sensor and the second acoustic sensor, identify a direction of an elevator system noise source based on a first time delay based on the first acoustic signal and the second acoustic signal.

A movement-distance measuring apparatus is provided with: an antenna, a phase detection circuit, a phase-shift calculation circuit, and a movement-distance calculation circuit. The antenna transmits a radio wave toward a plurality of reflectors arranged at constant intervals along a moving path of a moving object, and receives a reflected wave from the reflectors. The phase detection circuit detects a phase of the reflected wave received by the antenna. The phase-shift calculation circuit calculates a phase shift based on the phase detected by the phase detection circuit. The movement-distance calculation circuit calculates a movement distance of the moving object, based on the phase shift calculated by the phase-shift calculation circuit, and based on the interval of the reflectors.

Elevator systems including an elevator car moveable within an elevator shaft, the elevator car having a first elevator car component, the first elevator car component having a first side facing an interior of the elevator car and a second side opposite from the first side and a structural sound-generation system. The structural sound-generation system having at least one audio actuator coupled to the second side of the first elevator car component and an audio system controller in communication with the at least one audio actuator. The structural sound-generation system is configured to generate vibrations within the first elevator car component such that sound waves are produced therefrom and projected into the interior of the elevator car.

Elevator systems including an elevator car having a first elevator car door and an openable ceiling, the openable ceiling comprising a ceiling frame and an openable panel, the openable panel moveable from an open position to a closed position relative to the ceiling frame, an imaging device mounted to the openable panel and configured to capture image data of a detection zone that includes at least an opening formed by the first elevator car door when the openable panel is in the closed position, and a display located within the elevator car to display an image associated with the image data received from the imaging device. The openable panel is openable to create an access way that permits access from an interior of the elevator car to a top exterior of the elevator car.

A landing door of an elevator system has a door leaf equipped with an integrated floor display that indicates to a person the floor at which an elevator car approaching the floor of departure is currently located. The door leaf of the landing door has a wall element made of sheet metal, the floor display having at least one controllable light source arranged behind the wall element, and a cover layer. The wall element has a display segment with a plurality of light passage openings, the light passage openings forming a perforated screen structure. The cover layer functions such that after the light source is activated to display the desired floor information, light from the light source penetrates through the light passage openings and the cover layer to the outside and when the light source is deactivated, the cover layer does not let light through to the outside.
