摘要： The method according to the invention is a method for safeguarding the car of an elevator, which is provided to form regular unlocking zones in the region around the envisaged stopping points at the stories, against unintended movement. The method monitors the speed of the car, the height position of the car in the elevator shaft and the status of the locking of the car door, and identifies possible stopping of the car, the height position of the car outside a regular unlocking zone, and a possibly unlocked state of the car door. A first sub-method of the method forms a temporary unlocking zone when the car stops outside a regular unlocking zone with the car door unlocked, and it assigns the temporary unlocking zone an upper and a lower boundary above and below the position where the car stops.

摘要： Light grid for protecting the door edge of a motor-driven door against collision with an object, having a transmitter strip and a receiver strip with transmitter elements and receiver elements, for detecting an object in the plane of the door panels by interruption of the reception of individual receiver elements. An evaluation device distinguishes between normal and safety cases based on the detection of a status for the door, identifies the safety case if the number of uninterrupted receiving elements between door edge and object falls below a critical number, and identifies the normal case if the safety case is not identified. A communication device outputs a signal for the status. The evaluation device determines a distance value corresponding to the number of uninterrupted receiver elements below the door edge up to the first interrupted element, and the communication device varies the frequency as a function of the distance value.

摘要： An optoelectronic safety device for monitoring a machine movement includes a detection device and a control device. The detection device includes a transmitter unit which transmits an optical signal having a sequence of signal pulses, each of which has a different pulse intensity, and a receiver unit which receives the optical signal. The control device includes an evaluation unit which evaluates the optical signal received by the receiver unit, a pulse selection index, and a pulse selection unit which changes the pulse selection index if the pulse intensity of one of the signal pulses is outside of an optimal intensity range. The control device enables the machine movement if an intensity of a received signal is within a permissible intensity range, and outputs a trigger pulse to stop the machine movement if the intensity of the received signal is outside of the permissible intensity range.

摘要： An elevator system having an elevator car in an elevator shaft and having a measuring tape in the elevator shaft for determining the position of the elevator car in the elevator shaft. The measuring tape is arranged vertically in the elevator shaft and has optical coding for length measurement. At least one marking element which has optical marking is arranged on the measuring tape. The marking element is fixedly arranged on the measuring tape. A sensor device which comprises a lighting source and a sensor which form a detection field for detecting the measuring tape is attached to the elevator car. The elevator system comprises an evaluation device for decoding the codings in the detection field and a control device for controlling the elevator system as a function of the coding and/or of the position of the at least one marking element on the measuring tape.
