  • Patent number: 10336575
    Abstract: In elevator journey prioritization often calls for larger groups are prioritized. This is often misused by placing elevator calls for larger groups that are actually travelling. This problem can be reduced by identifying the calling person when placing the call and again in the elevator. The number of people in the elevator can be estimated by using machine vision or weight-based approximation methods. When the number of passengers is not known the possible misuse can be suspected if a person places considerably more group calls as than average.

    Abstract: In a power converter that converts a direct-current voltage into three-phase alternating-current voltages and outputs the three-phase alternating-current voltages to a power system. The power converter includes a microprocessor that sets a dead time during which high-side switching elements and low-side switching elements are simultaneously off, and carries out switching. Moreover, the microprocessor performs dq transformation using complex numbers of phase currents, and detects an amplitude value of d-axis current or q-axis current. The microprocessor changes a phase difference to reduce the amplitude value of d-axis current or q-axis current. The microprocessor then performs dead-time compensation on the basis of the resulting phase difference.

The elevator includes an enclosure located at each floor, two doors mounted to the enclosure, and a control unit to control the doors to open or close. The control method includes, capturing an image of a scene in front of the doors by a camera. Checking the image to determine whether there are people in front of the doors, and outputting a first control signal to the control unit to stop closing the doors upon the condition that there is a person in front of the doors.

  • Patent number: 8186484
    Abstract: An elevator system in which a controller monitors whether or not a speed of an ascending/descending body reaches a preset overspeed. At a time of maintenance work, a stopper is interposed between a buffer and the ascending/descending body to limit a lowered position of the ascending/descending body. A stopper detector detects installation of the stopper onto at least one of the buffer and the ascending/descending body. When the stopper is detected by the stopper detector, the controller lowers a set value of the overspeed.

  • Patent number: 8132653
    Abstract: An elevator door assembly (20) includes a positioner (30) for controlling an orientation of an elevator door panel (22) during movement between open and closed positions. The positioner (30) biases the door in a direction generally perpendicular to the desired direction of door movement. The disclosed example includes a first positioner member (32) that remains in a fixed position. A second positioner member (34) is supported for movement with the elevator door (22). In disclosed examples, at least one of the positioner members (32, 34) provides a magnetic field that results in the biasing force. In a disclosed example, opposing polarities on permanent magnets are arranged to provide a repulsive force between the positioner members (32, 34), which provides the biasing force on the elevator door.
