  • Controlling a drive motor of an elevator installation
    Patent number: 8863908
    Abstract: A movement of an elevator cage is detected by an elevator control on the basis of signals of a rotary encoder, coupled with a rotational movement of the drive motor or the drive pulley. Before movement of the cage begins, a movement plot in the form of a trip/speed profile is calculated for travel of the elevator cage from an instantaneous elevator cage position to a destination stopping point position. An anticipated slip between the drive pulley and a support means is included in the calculation of the trip/speed profile, and during the travel of the elevator cage a rotational movement of the drive motor and thus of the drive pulley is controlled by the elevator control in dependence on the calculated trip/speed profile and on signals of the rotary encoder.

  • Elevator access control system
    Patent number: 8857569
    Abstract: An elevator access control system monitors a secure area, including an elevator landing, and controls an elevator system with at least one elevator car that is accessible from the elevator landing. Each elevator car of the elevator system has a door at the landing that provides access between the elevator car and the landing. The system includes an access monitoring device that detects the presence of non-authorized individuals within the secure area and produces a breach signal upon detecting one or more non-authorized individuals within or entering the secure area. Upon receiving the breach signal, an access system controller in communication with the access monitoring device initiates a security alert phase.

  • Method for testing the tension stress in tension elements of tension element cord
    Patent number: 8813574
    Abstract: A method and device for testing the tensile stress in tension elements of a tension element cord utilizes a measuring gage which is clamped between two tension elements of the tension element cord. The gage establishes a reference point relative to a fixed point stationary with respect to the tension element cord. The gage extends horizontally between two vertically extending length portions of the two tension elements. Then it is determined whether the reference point of the measuring gage is shifted with respect to the fixed point in the horizontal direction, wherein such a shift is dependent on a difference in the tension stresses in the two tension elements.
