  • Publication number: 20140076686
    Abstract: A moving device including a driven conveyor, a control device for controlling the speed of the conveyor and a start-up sensor, which monitors a monitoring region in front of the moving device and outputs a start-up signal to the control device upon detecting an object, wherein, upon a provided start-up signal, the control device sets into motion or accelerates the moving device. The start-up sensor is a TOF sensor having (i) a light source for emitting modulated light, (ii) at least one receiving sensor for receiving light from the light source that is reflected at the object, and (iii) an evaluation electronic system configured for detecting, from the comparison of emitted and received light, the distance of the object from the TOF sensor and the position of the object in the space in front of the moving device.

  • Publication number: 20130269255
    Abstract: Monitoring apparatus for monitoring a movement element pivoted between open and closed states of an opening to be closed, the apparatus having a sensor for detecting an object and for monitoring a spatial angle originating at or near the rotation axis. The sensor is fitted at or near the rotation axis and includes a transmitter and receiver for transmitting and receiving radiation within the spatial angle. The sensor emits detection signals generated by the receiver when radiation is detected. The monitoring apparatus includes an evaluation unit that evaluates the detection signals depending on the angular position of the detected radiation in the spatial angle and determines whether an object has been detected and/or the position of the detected object. The evaluation unit draws a distinction between the movement element and an object depending on the current angular position of the movement element.

  • Publication number: 20130106601
    Abstract: A safety device for safeguarding a movable, guided movement element against undesired collisions with an object situated on a movement path of the movement element, said device comprising at least two sensors for detecting the object and the movement element and for outputting signals depending on the detection, and also having an evaluation unit for evaluating signals of the sensors and for generating a switch-off signal on the basis of the evaluation. For improved recognition of a risk of collision, the evaluation unit is designed to acquire from the at least two sensors a currently detected state vector from a set of state vectors which unambiguously comprise all possible combinations of the signals of the sensors, and to generate the switch-off signal in the case of predetermined state vectors.

  • Publication number: 20120150480
    Abstract: A monitoring sensor for detecting a test signal from an external signal generator at an input for receiving signals, to switch the monitoring sensor from a passive state to an active state when a signal is detected, to switch the monitoring sensor to a test state after a test period “t2” has expired, to change an output signal from an output of the monitoring sensor after an activation period “t3” has expired, this change in the output signal corresponding to a signal which arises when the monitoring sensor triggers a switching operation after an object has been detected, to convert the output signal to the initial state again after the withdrawal of the test signal has been detected, and to provide this renewed signal change as the signal for an external signal generator, the monitoring sensor changing to the monitoring state after this signal sequence.
