An illustrative example embodiment of an elevator compensation assembly includes a tie down mechanism and at least one compensation sheave that has an outer surface configured to engage at least one compensation rope member. At least one damper is associated with the tie down mechanism for resisting vertical movement of the tie down mechanism in at least one direction. At least one detector directly detects vertical movement of the tie down mechanism along the direction and provides an output indicating at least one characteristic of the detected vertical movement.

An elevator apparatus includes: a traction machine including a sheave around which a middle portion of a main rope from which a car and counterweight are suspended is wound; a controller configured to control travel of the car; a section specification unit configured to specify a determination target section serving as a travel section, including at least a travel position of the car, satisfying a predetermined determination execution condition; a sheave rotation detector configured to detect a sheave rotation amount; and a determinator configured to determine traction performance of the sheave based on the sheave rotation amount detected during travel of the car in the determination target section. The determination execution condition is to have a load weight and an acceleration of the car that cause direction of an acceleration vector of one of a car side and a counterweight side heavier than the other to match an ascent direction.

A method of monitors a climate quality within a building having an elevator running between floors of an elevator hoistway. The elevator car of the elevator includes at least an air-quality sensor. The method is characterized in that a fan of the elevator car is running when the door(s) of the car is/are opening at a floor station to suck air from the building's floor level into the elevator car to the vicinity of the air-quality sensor and sensing the air-quality by the sensor preceding to generating data of the air-quality.

There is provided a building facility vibration measurement device that can easily ascertain whether specs are sufficient for measurement of vibration of a building facility. A building facility vibration measurement device includes: an acceleration detection unit configured to detect acceleration; an acceleration collection unit configured to collect the acceleration detected by the acceleration detection unit; an accuracy calculation unit configured to calculate detection accuracy of the acceleration from information on the acceleration collected by the acceleration collection unit; and a judgement unit configured to, based on the detection accuracy calculated by the accuracy calculation unit, judge whether vibration of a building facility can be measured.

A conveyance system includes a transmitter configured to generate a signal; a receiver configured to receive the signal; the transmitter and receiver located so that the signal passes through a passenger area of the conveyance system; a controller configured to receive a signal strength of the signal received at the receiver; the controller configured to determine a loading factor in the passenger area in response to the signal received at the receiver.

A method for detecting an entry into an elevator car of an elevator system by a passenger uses a mobile device carried by the passenger. The mobile device has at least one, but in particular a plurality of sensors, with which the mobile device detects and evaluates measured values. An entry into the elevator car is then detected on the basis of comparing the measured values with at least one stored signal pattern.

A method of monitoring a conveyance apparatus within a conveyance system, the method including: obtaining a health level of the conveyance system at a first conveyance apparatus location; determining a first identifier for the first conveyance apparatus location; displaying the health level for the conveyance system at the first conveyance apparatus location and the first identifier for the first conveyance apparatus location on a display device; determining a current location of an individual within the conveyance system; and displaying the location of the individual within the conveyance system on the display device.

An illustrative example embodiment of an elevator system includes a plurality of components respectively configured for at least one function during operation of the elevator system. A plurality of sensors are each associated with at least one of the components. Each sensor senses at least one characteristic of an actual performance of an associated one of the components. A processor is configured to receive respective indications from the sensors regarding the actual performance of the associated components, determine a difference between the actual performance and a desired performance of any of the components based on the respective indications, and determine an adjustment to the operation of the elevator system based upon the determined difference.

A measuring tape (10) for determining the position of an elevator car (42) in an elevator shaft (41), the measuring tape being vertically disposable in the elevator shaft and preferably being disposable so as to extend across at least two building floors, the measuring tape having a tape-shaped base body (11) and a position coding which is capable of being read out by means of a magnetic field sensor and is made of ferromagnetic material, the tape-shaped base body (11) is made of textile material and the position coding is disposed so as to be inserted into the base body or so as to be applied to a surface of the base body (11).

An elevator control device, including an rpm detector, a landing-plate detector, and a controller, in which the controller includes a first remaining-distance calculating unit, which is configured to calculate a remaining distance to a destination floor as a first remaining distance based on the rpm, a second remaining-distance calculating unit, which is configured to calculate an ideal remaining distance from the detection of the landing plate to stop at a destination floor as a second remaining distance, an expansion-and-contraction amount estimating unit, which is configured to estimate an expansion amount of a governor rope from a difference value between the first remaining distance and the second remaining distance, and an expansion-and-contraction amount correcting unit, which is configured to correct the first remaining distance by adding a correction value calculated based on the estimated expansion amount.
