    • In this system for the securing of rooms, one or more transmitting elements emit suitably modulated light pulses into given regions or sectors which are produced by specially shaped optical components and/or by a special alignment of the transmitting elements and/or by the application of absorbent layers to an infrared filter which is located in front of the transmitting elements and receiving elements. One or more receiving elements receive the incident radiation. Changes in the radiation field with respect to intensity and/or speed of change of the intensity and/or phase are processed in subsequent evaluation logic circuitry. The room security system can also be combined into a larger unit with common evaluation logic.

    • An area-security system comprises a transmitting/receiving strip arranged along one side of an area to be secured and a reflection strip arranged along the other side. The transmitting/receiving strip is divided into transmitting regions and receiving regions, the transmitting regions consisting of a plurality of transmitting elements which are arranged alongside of each other and which are combined in at least two groups, and the receiving regions also consisting of a plurality of receiving elements which are arranged alongside of each other and are also combined in at least two groups. Modulated light from the transmitting elements strikes the receiving regions after being reflected by the reflection strip. A control circuit determines association of different groups of receiving elements with the individual groups of transmitting elements. A multi-channel evaluation, under the synchronizing control of a control circuit, evaluates the signals on the basis of various factors. The area-security system is particularly suitable for penetration-security or for entry-security application, and for the securing or control of machines.
    • 区域安全系统包括沿着要固定的区域的一侧布置的发送/接收条和沿着另一侧布置的反射条。 发送/接收条被分为发送区域和接收区域,发送区域由多个发送元件组成,这些发送元件彼此并排布置,并且被组合成至少两个组,并且接收区域也由多个 的接收元件,其彼此并排设置并且还组合在至少两组中。 来自发射元件的调制光在被反射条反射之后撞击接收区域。 控制电路确定不同组的接收元件与各组发射元件的关联。 在控制电路的同步控制下的多通道评估可以根据各种因素对信号进行评估。 区域安全系统特别适用于穿透安全性或进入安全应用,以及机器的安全或控制。
