An inquiry processing device includes: an automatic door information recorder that records information including past inquiry information from a customer regarding an automatic door, an operation situation, and quality information; a countermeasure presenter that presents recommended countermeasure information corresponding to a new inquiry regarding the automatic door by an extraction algorithm; a feedback information receiver that receives feedback information on whether or not a defect of the automatic door has been removed by taking measures on the basis of the recommended countermeasure information; a learner that updates the extraction algorithm of the countermeasure presenter on the basis of the feedback information; and a countermeasure presentation determiner that causes the countermeasure presenter to present new recommended countermeasure information by the extraction algorithm updated by the learner, when it is determined that the defect of the automatic door has not been removed.

Detecting passengers traveling through a transit gate, includes transmitting a first beam from a first optical emitter on a side of the transit gate to a first plurality of optical receivers on an opposite side of the transit gate, and transmitting a second beam from a second optical emitter on the opposite side of the transit gate to a second plurality of optical receivers on the side of the transit gate in a direction opposite the direction of the first beam. Transmit intensities are adjusted based on learned patterns or drifts in the receive intensities of light beams. Detection times are reduced based on pairing additional optical receivers with a single optical emitter.

The invention relates to a control system for driving a motorized closure element of a motor vehicle, wherein, in order to detect operator control events, at least one sensor control means and at least one elongate distance sensor which extends along a sensor extent are provided, wherein the sensor control means drives the associated distance sensor and/or evaluates the sensor signals from said distance sensor, and wherein the distance sensor detects a distance from a user. It is proposed that, with the control system installed, a vehicle component is arranged or can be arranged in or along the sensor extent, and that the distance sensor is designed such that it has a blind section in the region of the vehicle component, said blind section having no sensitivity or a lower level of sensitivity compared to that region of the distance sensor which adjoins the blind section.

The invention relates to a device for monitoring the door area of an at least partially glazed door. The device comprises a transmitter, an image recorder, a control unit, and an evaluation unit. The transmitter is used to emit at least one transmission pulse of electromagnetic radiation. The image recorder comprises a receiver matrix having at least one first receiver block, which has a plurality of first receivers. The first receivers of the first receiver block are designed and arranged in such a way that they receive reflected signal components of the transmission pulse in a second predetermined distance range of an outer region of the door area, the distance range being determined in relation to the door. Each first receiver has a memory unit which is designed to integrate and store the reflected signal components received. The control unit is configured to trigger a transmission pulse of the transmitter and to activate the first receivers of the first receiver block for a predetermined first receiving period after a predetermined first idle period which is longer than a period in which a signal of the transmission pulse reflected by the glazed door reaches the first receivers of the first receiver block. The evaluation unit is configured to read the stored signal components of the respective receiver and to process them into topography image data and to compare the topography image data with stored reference image data for a free door area, or is configured to read the stored signal components of the respective receiver and to determine a distance value on that basis and to compare the respective distance value with a stored reference value for a free door area.

The invention relates to a Sensor (10) for controlling an automatic door, where the sensor (10) comprises a laser scanner (12) for detecting the presence of an object, with at least one laser curtain (22, 32, 34) in a predefined detection area of the scanning field, where the sensor (10) comprises a distance data acquisition unit (13) that is embodied to acquire the distances of the points of reflection of the reflected signal by evaluation of time of flight, a presence detection unit (15), where the result of the distance data acquisition unit (13) is fed to the presence detection unit (15), where the distance data acquisition unit (13) forwards the distance data information to the presence detection unit (15), where the presence detection unit (15) evaluates, if an object is detected within the predefined detection area by analysing the distance data, where a presence detection information is created and fed to an at least one sensor output port (18, 18b). The invention is characterized in that the sensor further comprises an object information unit (11) comprising a human body identification unit (16), where the object information unit (11) receives the distance data, and the human body identification unit (16) uses the distance data to determine if the detected object is a human body, where the object information unit (11) creates an object information that is fed to the at least one output port (18, 18a).

A safety curtain and system includes multiple light emitters and multiple light receivers to detect traffic approaching a doorway. The safety curtain my include pairs of multiple light emitters and receivers positioned on both sides of a passageway (doorway) so as to detect approaching traffic. The multiple light emitters and light receivers may detect a height of an approaching traffic (e.g., person or vehicle) and initiate warning lights of a possible door closing. The detected approach of traffic may cause the door to be stopped, reversed or slow down. The system may include a computer to monitor the signals from the receivers and may control the motion of the door.
