Disclosed is a system for installing a sensor to a passenger conveyance system, wherein the sensor is configured for being positioned on the passenger conveyance system; and an on-board indicator or a mobile device is in communication with the sensor, configured for providing feedback indicative of whether the sensor is aligned to an axis within an alignment tolerance.

An illustrative example embodiment of a device that facilitates installing at least one elevator door component, includes a detector that is configured to detect at least one reference feature in a vicinity of a desired position of the elevator door component. A processor is configured to use information from the detector to determine the desired position of the elevator door component relative to the at least one detected feature. An indicator is configured to provide at least one indication corresponding to the desired position of the elevator door component.

A method for determining a mapping of a number of floors to be served by an elevator includes the steps of: (a) determining, during a multiplicity of trips of an elevator car of the elevator, a trip-dependent physical parameter value which unambiguously depends on at least one of a trip duration and a trip distance; and (b) clustering the determined trip-dependent physical parameter values to clusters to define each of the floors in the mapping. In a training phase, the method automatically determines the number of floors served and then, in an operation phase, classifies each of the observed trips and finally detects and tracks a current position of the elevator car. An elevator monitoring device implementing such method may be retrofitted into existing elevators for e.g. remotely monitoring the elevator operation and does not necessarily require any data transfer between components of the elevator and the elevator monitoring device.

An elevator safety monitoring system, an elevator system, an elevator drive unit, and a method for operating an elevator are presented. The elevator safety monitoring system includes an elevator car absolute position and speed feedback device, a safety monitor connected to the absolute position and speed feedback device, and a safety zone extending inside an elevator shaft. The safety zone is associated with an allowable maximum speed of an elevator car, wherein the allowable maximum speed is lower than a rated speed of an elevator car outside the safety zone, wherein the safety monitor is configured to determine a slowdown failure of the elevator car approaching the safety zone, and, upon the determination of the slowdown failure, command an actuator to decelerate the elevator car to the allowable maximum speed.

An emergency terminal stopping system for an elevator system, the emergency terminal stopping system including: a sensor configured to determine data related to the motion of an elevator car moving within an elevator hoistway; at least one elevator brake configured to halt the motion of the elevator car; at least one elevator safety gear device provided on the elevator car; and at least one buffer provided at a lower portion of the hoistway.

The present invention is about a system and method for evaluating the movement of an elevator car within a hoistway. The same is based on gathering movement data of the car by means of a rotation encoder or acceleration sensor. Since these data are counted pulses there is a need to convert them into real movement data. This conversion is calibrated automatically by comparing the movement data with a length distance being passed by the car, wherein said length distance is configured to be unchangeable over the time. Base on the exact movement results gained therewith by means of said calibration one also gets better position results of the car in the hoistway.

There is a method, a system, and a computer program product that receives information from a set of on-line source and projects the information by devices positioned above elevator doors according to a criteria. Each digital projection system may be independently operated, powered and connected through a server which is controlled and monitored by the building's operations center. Each unit is capable of streaming pre-recorded advertised informational display separately or the operations center can synchronize all the digital projection systems within the building to function as a single unit in the case of live information feed or in case of emergency.

This invention relates to a method for defining absolute position information of an elevator car. The method comprises: obtaining continuously a pulse position information of the elevator car; and defining an absolute position information of the elevator car by adding a predefined correction value to the obtained pulse position information of the elevator car. The predefined correction value indicates a drift between the obtained pulse position information of the elevator car and the actual pulse position of the elevator car. The invention also relates to a safety control unit and an elevator system performing at least partly the method.

A method of controlling an elevator car (22) includes driving the elevator car (22) with a drive system (30) including a drive device (32) and a brake device (36); detecting an emergency stop condition; triggering the brake device (36) in response to detecting an emergency stop condition; determining a delay to be applied between triggering the brake device (36) and stopping the drive device (32); and waiting for a time period corresponding to the delay before stopping the drive device (32).

An elevator system includes a car that ascends and descends a hoist way, a power feeding device installed at a specific power feeding point of the hoist way, a power receiving device that receives power from the power feeding device when the car stops at the power feeding point, a battery that is charged by the received power, and an elevator control panel that controls ascent and descent of the car. When the remaining capacity of the battery is equal to or less than a predetermined capacity, the elevator control panel performs a rescue operation of a passenger in the car, and after the rescue operation, performs an automatic search operation of searching for a power feeding point where the power feeding device is installed according to the remaining capacity of the battery.
