    • A method of, and apparatus for, detecting an intrusion into a volume defined relative to a path across an opening along which path a closure member for the opening can be controllably displaced to define a gap in the opening, the gap being bounded on one side by the closure member and on the other side to the one side by a boundary member; the volume including at least one threshold region on at least one side of the path; the volume having as a base the threshold region and rising above the threshold region; a first group of at least two emitters of electromagnetic signals located on either the closure member or the boundary and directed into the volume and a second group of at least two receivers for electromagnetic signals located on the opposite side of the gap to the emitters; emissions from the emitters being directed into the volume but not directly towards the receivers; the emitters and receivers forming part of a network including processing means which form a compound sensor for use in monitoring operation of the closure member and for defining sensitivity to an intrusion into a region or regions of the volume; each emitter being adapted to direct a primary beam of e.m. radiation into the volume; each receiver being adapted to receive a secondary beam generated by the reflection of a primary beam from a target intruding into the volume; the method comprising the steps of: causing at least one of the emitters to emit a primary beam along a first axis into the volume; allowing for at least one of the receivers to receive a secondary beam of radiation along a second axis from the volume; the secondary beam being generated by reflection of a primary beam from a target intruding into the volume; the secondary beam being generated in the volume by way of, but not constituted by, the or any primary beam from an emitter;and enabling one or more of the receivers to provide an output signal into the network of the compound receiver characteristic of the, or each, secondary beam detected by at least one of the receivers in the second group;and providing that where the compound sensor serves to establish: that when an excess gain ratio is relatively small in an output signal from a single receiver caused by reception by the receiver of a secondary beam and the size of the gap is relatively large then the compound sensor functions so as to increase sensitivity of detection existing within a given predetermined region of the volume by comparison with sensitivity in another region or regions in the volume; that when an excess gain ratio is relatively large in an output signal from a single receiver caused by reception by the receiver of a secondary beam and the size of the gap is reducing or small then the sensor functions so as to increase sensitivity of detection within more than one region of the volume by comparison with sensitivity in another region or regions in the volume.
    • 本发明涉及一种用于检测侵入到相对于穿过开口的路径限定的体积的方法和设备,该开口沿着该路径可以可控制地移动开口的封闭构件以限定开口中的间隙,该间隙在一侧 通过封闭构件并且在另一侧由边界构件向一侧施加; 该体积在路径的至少一侧上包括至少一个阈值区域; 该体积具有作为阈值区域的基础并且升高到阈值区域之上; 第一组至少两个电磁信号发射器,其位于封闭构件或边界上并且被引导到所述体积中,并且第二组至少两个接收器用于电磁信号,所述电磁信号位于所述间隙的与发射器相反的一侧上; 来自发射器的排放物被引导到容积中,但不直接朝向接收器; 所述发射器和接收器形成网络的一部分,所述网络包括形成复合传感器的处理装置,所述复合传感器用于监测所述闭合构件的操作并且用于限定对侵入所述体积的一个或多个区域的灵敏度; 每个发射器适于引导e.m.的主要波束。 辐射入体积; 每个接收器适于接收通过来自侵入所述体积中的目标的主射束的反射而产生的次级射束; 所述方法包括以下步骤:使所述发射器中的至少一个沿着第一轴线发射主束到所述体积中; 允许所述接收器中的至少一个接收从所述体积沿着第二轴的次级辐射束; 所述次级束由来自侵入所述体积的目标的主束的反射而产生; 通过但不是由来自发射器的任何主波束或由任何发射器的任何主波束构成次级波束;以及使得一个或多个接收器能够将输出信号提供到复合接收器的网络中, 或每个由第二组中的接收机中的至少一个接收机检测到的辅助波束;以及在复合传感器用于建立以下情况时提供:当来自单个接收机的输出信号中的过量增益比相对较小 次光束的接收器和间隙的尺寸相对较大,则复合传感器起作用,以便通过与体积中的另一个区域或区域中的灵敏度相比,增加存在于该体积的给定预定区域内的检测的灵敏度; 当由接收机接收到次级光束引起的来自单个接收机的输出信号中的过量增益比相对较大并且间隙的大小减小或小时,则传感器起作用以在更多内部增加检测灵敏度 通过与体积中的另一个区域或多个区域的灵敏度相比而比该体积的一个区域更小。
