According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.

Provided are embodiment for a method and a system for filtering unintended requests. The embodiments can include receiving an input to disable an elevator lock for an elevator car, and determining whether to unlock the elevator lock. The embodiments can also include unlocking the elevator lock based at least in part on the determination and permitting or prohibiting motion of the elevator car responsive to the determination.

An illustrative example embodiment of an elevator tension member monitor includes an optoelectronic detector configured to be situated near the elevator tension member. The optoelectronic detector provides an output corresponding to a profile of the elevator tension member. A processor receives the output from the optoelectronic detector and determines whether there are any anomalies in the profile of the elevator tension member. The processor reports any determined anomaly in the profile of the elevator tension member.

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.

A detection system is provided. The detection system includes a sensing device and a controller. The sensing device is within an elevator and in communication with the controller. The sensing device continuously monitors sound waves within the elevator and communicates the sound waves as electrical signals to the controller. The controller operates the elevator and analyses the sound waves received as the electrical signals from the sensing device to detect an emergency condition within the elevator.

According to one embodiment, an elevator passenger detection system comprises an image capturing unit, a detection area setting unit, and a detection processing unit. The image capturing unit captures an image in a predetermined range including a vicinity of a doorway at which a door is opened or closed, from an inside of a car. The detection area setting unit sets a detection area on a front return panel provided on at least one of sides of a doorway of the car, on the captured image obtained by the image capturing unit. The detection processing unit detects presence of a passenger or an object, based on the image in the detection area set by the detection area setting unit.

A method of operating an elevator system using a touchless elevator communication system including: generating a first two-dimensional sensor curtain using a first sensor curtain generation device, the first two-dimensional sensor curtain being located in front of a display that displays one or more selection options; generating a second two-dimensional sensor curtain using a second sensor curtain generation device located in front of the first two-dimensional sensor curtain, the first two-dimensional sensor curtain being located between the second two-dimensional sensor curtain and the display; detecting the object in the second two-dimensional sensor curtain; determining a second curtain location of the object in the second two-dimensional sensor curtain; mapping the second curtain location of the object in the second two-dimensional sensor curtain to a selection option of the one or more selection options; and identifying on the display that the object is pointing to the selection option.

An elevator notice system for an elevator system includes at least one hoistway defined by a structure having a plurality of areas with each area having at least one gate and at least one car in each of the at least one hoistway. At least one of the at least one gate is associated with a respective hoistway. The elevator notice system includes a controller and a programmable display. The controller is configured to control the display and track the current location and scheduled destination of each of the at least one car in each of the at least one hoistway. The programmable display includes a car identification portion displaying a car identification type associated with a specific car of the at least one car, and is configured to display at least a next area destination associated with the specific car.

Typically a technician is physically present to investigate a malfunction of an elevator system. Devices, systems and methods are provided for actively monitoring one or more lift devices, such as elevators and escalators. A computing system for electrically controlling an elevator controller, includes: a field board electrically connected to an elevator controller, and the field board communicates with a computing platform device, which in turn is connected to a server over the Internet. The field board includes relay switches that are electrically connected to the elevator controller. The server sends poking commands that triggers a relay switch to open or close, which causes the elevator controller to generate a call signal to move the elevator to an upper or a lower floor. If the elevator does not move according to a poking command, then a malfunction is reported.

An elevator brake, having a rotatable component mounted to a shaft, is monitored for contamination by projecting electromagnetic radiation onto the rotatable component or onto the shaft, and receiving reflected electromagnetic radiation. If the monitored zone on the rotatable component or the shaft becomes contaminated, for example with oil or grease, the nature of the electromagnetic radiation reflected from the zone will change noticeably.
