Abstract:
Das Türsystem besteht aus einem Türrahmen (1) und mindestens einem Türblatt (2) sowie einem Türantrieb (3) mit Steuereinheit. Das Türblatt (2) ist mit einem Handvenen-Scanner (4) ausgerüstet, zur Erfassung des Handvenen-Profils bei beabstandetem Hinhalten der Hand vor den Handvenen-Scanner (4) zwecks Erkennung des Benutzers. Eine programmierbare Rechnereinheit (5) mit Speicherelement ist im Innern des Türblattes (2) untergebracht, in der eine Anzahl von Benutzer-Handvenenprofilen speicherbar ist. Ein Handvenen-Profil wird mit den im Speicherelement der Rechnereinheit (5) gespeicherten Handvenen-Profilen verglichen und je nach Übereinstimmung wird die Tür geöffnet oder nicht. Die Programmierung und Stromversorgung der Rechnereinheit (5) erfolgt über eine im Türblattrand (8) oder im Randbereich (9) mündende Netzwerk-Schnittstelle (10), die neben dem Signalkabel (6) für die Steuereinheit des Türantriebs (3) die einzige Schnittstelle zwischen Türblatt (2) und Türrahmen (1) bildet. Durch den temporären Anschluss eines externen Rechners (7) an diese Netzwerk-Schnittstelle (10) kann die Rechnereinheit (5) programmiert werden. Zudem dient die Netzwerk-Schnittstelle (10) zum Anschluss einer Stromversorgung für die Rechnereinheit (5).
Abstract:
The present invention relates to a system for controlling entrance gates to store localities in particular or to other localities open to the public. The entrance system includes an entrance passageway which is defined by posts on which gates are pivotally mounted. A sensor means functions to detect the presence of people and objects in the vicinity of the passageway and to deliver signals to a control means for controlling opening and closing of the gate. The sensing means includes at least one sonar (8, 9) which is mounted in or in the vicinity of the passageway (2) and which comprises a transmitter/receiver means for transmitting ultrasonic pulses and receiving ultrasonic pulses that are reflected from objects and persons located within the defined measuring area.
Abstract:
Die Erfindung betrifft ein optisches Sensorsystem (14) für ein Kraftfahrzeug (10), welches dazu ausgebildet ist, einen außerhalb des Kraftfahrzeugs (10) liegenden ersten Überwachungsbereich (22) zu überwachen und bei Detektion eines durch den Fahrzeugnutzer in den ersten Überwachungsbereich (22) bewegten Körperteils oder Gegenstands die Öffnung einer Tür oder Klappe (12) des Kraftfahrzeugs (10) auszulösen. Das Sensorsystem (14) ist ferner dazu ausgebildet, einen zweiten Überwachungsbereich (36) in der Umgebung der Tür oder Klappe (12) zu überwachen und bei Detektion eines Hindernisses in dem zweiten Überwachungsbereich (36) einen Öffnungsvorgang der Tür oder Klappe (12) zu stoppen.
Abstract:
The present invention concerns a motorized door having a shutter for closing and opening an area. The door comprises a series of sensors mounted on or adjacent to a leading edge of the shutter and wherein the sensors comprise ultrasonic emitter/receiver units configured for detecting the presence of an obstacle both in the opening plane of the door as well as in an approaching zone located near the opening area of the door. The door comprises a controller configured to distinguish an accidental obstacle from a non-accidental obstacle and instantly stop the movement of the leading edge when an accidental obstacle is observed during closing of the door.
Abstract:
An ultrasonic sensor system for automatic door openers of a swinging door type has at least one and preferably three microprocessor (45) controlled ultrasonic beam transducers (40, 41) for projecting expanding unidirectional ultrasonic beams in a detection zone SDZ in the path of the swinging door and for converting reflected single multiple path signals into an acoustical image of objects in the selected detection zone. This acoustical image is stored and compared with a later acoustical image of an object in the detection zone and used to signal a lack of correlation between the first and second acoustical images to produce a signal preventing operation of the door opening. Aspect ambiguities and problems of acoustic "transparency" are avoided by using direct multiple path reflections of more than one ultrasonic beam transducer projecting crossing beams and which have their signals multiplexed, controlled, and processed by a single computer microprocessor chip (45).

Abstract:
A presence detector for a door assembly which includes a door closing a door entrance is described herein. The detector comprises a transducer assembly mounted to the door assembly for emitting at least one ultrasound detecting beam adjacent the door entrance and for triggering a detecting signal indicative of a body located adjacent the door entrance when the body intersects the at least one ultrasound detecting beam and a controller for receiving information indicative of a position of the door and for controlling the emission of the at least one detecting beam accordingly with the position of the door. The detector assembly operates in crossing, ranging or dual modes.
Abstract:
A proximity detector in which a sensor unit (10) senses reflected energy received from a predetermined volume or zone and generates an electrical signal representative of the received energy. Circuit means process the received signals to control the operation of apparatus such as automatic doors. One aspect of the invention is concerned with the sensor unit in which transmitters (14) are located in a housing with a receiver (15). The housing has a filter (7) through which infrared radiation can be transmitted and received. Mask areas on the filter define the zone into which radiation can be transmitted and from which it can be received. The filter is interchangeable so that zones of different sizes and dimensions can be provided. Another aspect is concerned with novel signal processing circuitry and a further aspect is concerned with an ultrasonic system wherein a multiplier is used to process the received signals.
Abstract:
A movable door incorporates a proximity detection system for sensing obstructions in the path of the door. The system comprises an array of transmitter/receiver pairs (21, 22 and 23), each pair comprising a transmitter (1) for transmitting an energy pulse, a receiver (2) located adjacent the transmitter and directed to receive any reflected transmitter pulses, and a shielding (3) for shielding the receiver (2) from receiving energy pulses directly from the transmitter (1). At least two transmitter/receiver pairs (21, 23) are mounted on a leading edge or face of the door (12) to transmit energy pulses in a direction which is not at right angles to the leading surface or edge of the door, to monitor for obstructions in the path of the door (12). Another two transmitter/receiver pairs (26 and 28) are mounted on the leading edge or surface of the door (12) to transmit energy pulses at right angles to the surface or edge of the door (12). Different transmitter/receiver pairs may transmit on different frequencies, and means for suppressing unwanted reflected signals is provided. Means for transmitting data signals on a two-conductor power supply cable for the system is disclosed.
