The invention relates to an automatic door and method for controlling an automatic door (), comprising a door controller unit () for controlling a door, acting on a door drive; further comprising a monitoring system () comprising at least two door sensors () mounted on two opposite sides of the door, as seen in passage direction, where each of said sensors () comprises a scanning unit () that monitors a sensor safety area, where a safety signal is applied to the door controller unit upon detection of an object within the sensor safety areas of said sensors. According to the invention after a predefined timespan (TL) of no detection within said sensor safety areas of said sensors, the monitoring system () is set to a 'restricted mode' in which at least one sensor safety area is set to a restricted area, where the safety signal is then provided upon detection of an object within the restricted area, where further, once a detection in the restricted area occurs, the monitoring system is set back to an unrestricted “normal” mode.

Automatic door

A door sensor may include one or more emitters configured to emit an emission beam comprising IR light during an emitting phase. The door sensor may further include one or more receptors configured to receive a reception beam comprising the IR light reflected off of a surface during a listening phase and an interference beam from an adjacent door sensor. The door sensor may further include a controller operatively coupled to a memory storing computer-readable instructions that, when executed by the controller, cause the controller to: determine one or more of the frequency and phase of the interference beam; determine whether the door sensor should be primary or secondary to the adjacent door sensor; and adjust a timing of one or more of the emitting phase and the listening phase to reduce interference from the adjacent door sensor.

Methods and systems for infrared synchronization

An infrared (IR) sensor for use in a door sensor. The IR sensor may include a plurality of emitters arranged in multiple rows. Each emitter of the plurality of emitters may be configured to emit an emission beam comprising IR light. A plurality of receptors may be arranged in multiple rows. Each receptor of the plurality of receptors may be configured to receive a reception beam comprising the IR light reflected off of a surface. One or more lenses comprising refractive elements may be configured to duplicate and direct one or more of the emission beams and one or more of the reception beams onto the surface to form an IR pattern. The IR pattern may include multiple IR curtains. One or more of the receptors and/or emitters may be deactivated to change a width of the IR pattern and/or number of IR curtains.

Infrared curtain systems and methods

The present invention relates to a sensor () for use with an automatic door comprising at least two detectors () based on different technologies, a processor () for processing the signals generated by at least two detectors () in that it simultaneously uses the signals in order to combine the signals and to accurately detect the situation in a surveillance area () sensed by the sensor ().

Sensor for use with automatic doors

A measurement sensor comprising a PSD () as an optoelectronic receiver, a transmitter () for generating spots (), optics () for reproducing the spots (') on the PSD () and means () for processing output signals (I, I) generated by said PSD () and for controlling the transmitter () depending on the processed output signals (I, I) in order to measure the distance between the target () and the sensor by a triangulation technique is disclose closed. The transmitter comprises at least two optoelectronic signal sources () for projecting at least two spots () independent from each other on a target (), the means () comprising a digitally controlled potentiometer () for balancing the output signals (I, I) and a digital processor () adapted for controlling the potentiometer ().
