A detecting system for an automatic door is provided including a TOF camera having a field of view that is limited in a first zone for a first purpose such as safety and in a second zone for another purpose such as activation or counting. The proposed system can be used for example in powered pedestrian doors, bus, rail, etc. In some embodiments, at least one ultrasound sensor system is further provided. The two technologies share hardware and information, resulting in improved safety and counting functions of the system, while reducing the amount of hardware used, space requirement and unit cost, and improving performance.

A method and a device for monitoring an elevator car door acquire one or more distances based on light emitted toward the car door by a distance measuring device and reflected at the car door as a function of a current closed state of the car door. Information about the current closed state of the car door is derived solely by comparing the acquired distance with a previously acquired reference distance, and a signal which represents the information can be fed to a remotely arranged control center. The monitoring device can be installed as a retrofit component that is capable of working autonomously in existing elevator systems, does not need to receive any data from a controller of the car door or the elevator system and only requires a relatively simple data processing device that only needs to carry out a comparison of detected distance values with reference values.

A zone object detection system including a passenger compartment. Also included is a door moveable between an opened position and a closed position. Further included is a first sensor monitoring a first zone outside of a plane of the door. Yet further included is a second sensor monitoring a second zone comprising at least one of the plane of the door and outside of the plane of the door. Also included is a controller in operative communication with the first sensor and the second sensor, the controller commanding a first modification of a door closing movement of the door if an object is detected in the first zone, the controller commanding a second modification of the door closing movement of the door if an object is detected in the second zone.

An elevator system (2) comprises at least one elevator car (6) moving within a hoistway (4); at least one door (10, 11) providing access to the elevator car (6); at least one passenger sensor (21) configured for detecting passengers (30) in the vicinity of the at least one door (10, 11); and a door control device (22) configured for controlling the at least one door (10, 11). The door control device (22) comprises a memory (24) in which at least one predefined movement profile is stored; a modificator (28) configured for modifying the at least one predefined movement profile when the at least one passenger sensor (21) detects a passenger (30) in the vicinity of the at least one door (10, 11); and a door controller (26) configured for controlling the movement of the at least one door (10, 11) based on the at least one movement profile.

Embodiments include techniques for operating an elevator safety control system and method. The techniques include charging one or more portions of an elevator system, the elevator system includes an elevator door and elevator frame, and monitoring a charge on the one or more portions of the elevator system. In addition, the techniques include detecting a change in the charge on the one or more portions of the elevator system, and responsive to the detection, controlling an operation of the elevator door.

An object sensing assembly for an elevator system. The object sensing assembly includes an elevator door moveable between an opened position and a closed position. Also included is a pressure sensor assembly located on a leading edge of the elevator door. The pressure sensor assembly includes a plurality of pressure sensors located at different height locations along the leading edge of the elevator door. The pressure sensor assembly also includes a controller in operative communication with the plurality of pressure sensors, the controller opening the elevator door if a pressure differential is detected between the plurality of pressure sensors.
