Abstract

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.

• E05F 15/74 - Power-operated mechanisms for wings with automatic actuation responsive to movement or presence of persons or objects using photoelectric cells
• E05F 15/43 - Detection using safety edges responsive to disruption of energy beams, e.g. light or sound
• G01V 8/20 - Detecting, e.g. by using light barriers using multiple transmitters or receivers

Abstract

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.

Abstract

An infrared (IR) sensor for use in a door sensor. The IR sensor may include one or more rows of emitters configured to generate an emission beam. The emission beam may have a width that is at least a width of an opening below the door sensor. The IR sensor may also include one or more rows of receptors configured to receive an evaluation beam. The receptor beam may have a maximum width that is at least the width of the opening. At least a portion of the receptors may be further configured to be one or more of deactivated and ignored, such that the width of the evaluation beam is reduced to correspond with a reduced width of the opening during a closing of a door.
