    • An intruder detection system is provided in which a detection range can be set to a predetermined one so that false detection caused by a moving object outside the predetermined range can be diminished. The system includes a transmission-side leaky transmission line that radiates a detection signal for detecting an intruder and a reception-side leaky transmission line that receives a detection signal leaked from the transmission-side leaky transmission line, both of which are buried spaced apart from each other in a detection surveillance area, and detects the presence/absence of an intruder in the detection surveillance area based on variations in the detection signal received by the reception-side leaky transmission line, wherein at least part of either the transmission-side leaky transmission line or the reception-side leaky transmission line is made of a surface-wave-type leaky coaxial transmission line, and the other leaky transmission line, a radiation-type leaky coaxial transmission line.
    • 提供一种入侵者检测系统,其中可以将检测范围设置为预定的检测范围,从而可以减少由预定范围之外的移动物体引起的错误检测。 该系统包括发射侧泄漏传输线,其辐射用于检测入侵者的检测信号和接收侧泄漏传输线,其接收从发送侧泄漏传输线泄漏的检测信号,两者都被掩埋在与 在检测监视区域中彼此相对,并且基于由接收侧泄漏传输线接收到的检测信号的变化来检测入侵者在检测监视区域中的存在/不存在,其中发送侧泄漏的至少一部分 传输线或接收侧泄漏传输线由表面波型泄漏同轴传输线和另一个泄漏传输线,辐射型泄漏同轴传输线构成。

    • A perimeter monitoring system is arranged to detect passage across a perimeter of an area. The system primarily includes an emitter, a retroreflector, a detector and an alarm. The emitter provides a modulated visible laser beam. The retroreflector is arranged to direct the beam along a segment of the perimeter and return the beam along the segment. The detector includes a device that blocks reception of light outside an angle of less than 5 degrees. One or more local or remote alarms are activated in response to the signal. For example, a remote alarm is located on the inside of a residence window where it is activated by another visible laser beam. Alignment of the peripheral monitoring system is less costly and false alarms are less likely than with known systems.
    • 周边监测系统被布置成检测通过一个区域周边的通道。 该系统主要包括发射器,后向反射器,检测器和报警器。 发射器提供调制的可见激光束。 后向反射器布置成沿着周边的一段引导光束并且沿着光束返回光束。 该检测器包括阻挡小于5度角的光的接收的装置。 响应信号激活一个或多个本地或远程报警。 例如,远程警报器位于居住窗口的内部,在其中由另一个可见激光束激活。 外围监视系统的对准成本较低,并且虚假报警的可能性低于已知系统。

    • An adjustable bracket and housing assembly mountable to any horizontal or verticle surface designed primarily for passive infrared detective for security systems. The bracket has a mounting member (30), a cylindrical member (20) allowing horizontal adjustability of the housing assembly and a bracket arm (15) having teeth (21) for vertical adjustability of the housing assembly. The housing assembly has a base (10) and removable cover (12). The base is attachable to the bracket arm (15) by a screw (29). The housing assembly cannot be adjusted directionally, unless the cover (12) is removed, thereby providing access to the screw (29). This latter feature makes the unit of the present invention tamper proof as an alarm will be triggered if the cover (12) is removed from the housing assembly.
    • 可调节的支架和外壳组件可安装到任何水平或垂直面,主要用于安全系统的被动红外探测器。 支架具有安装构件(30),允许壳体组件的水平可调节性的圆柱形构件(20)和具有用于壳体组件的垂直可调性的齿(21)的支架臂(15)。 壳体组件具有基部(10)和可移除的盖(12)。 基座通过螺钉(29)可附接到支架臂(15)。 壳体组件不能定向地调节,除非盖子(12)被移除,从而提供对螺钉(29)的通路。 后一个特征使得本发明的单元防篡改,因为如果从壳体组件移除盖(12),则将触发警报。

    • A visual display system detects and continuously displays the location of a breach in a protected building or secure area. Each of a plurality of exclusive OR gates is connected to a separate reed-type sensor switch. Each exclusive OR gate output is connected to a flip-flop network, each of which in turn is connected to a light emitting diode. Activation of a sensor switch results in lighting only of the light emitting diode associated with the area breached. A mechanism is also provided for preventing the generation of false alarms by transients or inadvertent momentary opening of any of the sensor switches.
