    • A rotatable wireless electrical coupler is disclosed that presents a wireless alternative to mechanical slip rings, such as are used in rotatable mechanical assemblies such as dome cameras. The rotatable wireless electrical coupler is designed to provide for the wireless transfer therethrough of electrical power, video and data signals. A rotatable multi-function transformer of the electrical coupler is designed primarily for the transfer of electrical power therethrough, and can also be used for the transfer of data signals. A rotatable electrical capacitor of the electrical coupler is designed primarily for the transfer of video data signals therethrough, and can also be used for the transfer of control and feedback data signals. In a dome camera, the rotatable wireless electrical coupler transfers power and data signals to and from a rotatable platform/section on which is mounted a video camera, pan and tilt motors and other associated electrical components.
    • 公开了一种可旋转的无线电耦合器,其呈现机械滑环的无线替代物,例如用于可旋转的机械组件,例如球型照相机。 可旋转无线电耦合器被设计为提供电力,视频和数据信号的无线传输。 电耦合器的可旋转多功能变压器主要用于通过其传输电力,并且还可以用于数据信号的传送。 电耦合器的可旋转电容器主要用于通过其传输视频数据信号,并且还可用于传送控制和反馈数据信号。 在圆顶照相机中,可旋转的无线电耦合器将功率和数据信号传送到安装有摄像机,摇摄和倾斜电机以及其它相关联的电气部件的可旋转平台/部分。

    • A ceiling-mounted passive infrared detector assembly (30) that has three main components: a junction box (10) which is adapted to be mounted within an opening in a ceiling; a cover (44) adapted to mate with the junction box (10); and an electronic passive infrared detector subassembly (43) including an infrared sensor (42) and processing circuitry (45) for processing electrical signals generated by the infrared sensor (42) and producing output signals. The cover (44) has mounting means such as a flange (48) adapted to mount to the junction box (10) (or directly to a ceiling if a junction box is not used) and an extended portion (50) with a cavity (52) and an aperture (46). The cover (44) also has a lens array (36) located across the aperture (46). The electronic passive infrared detector subassembly (43) is located with respect to the cover (44) such that the infrared sensor (42) is aligned with the lens array (36) when the cover (44) is mounted to the junction box (10) such that the infrared sensor (42) detects infrared energy passed through the lens array (36) from a field of view defined by the juxtaposition of the lens array (36) and the infrared sensor (42).
    • 一种天花板安装的被动红外探测器组件(30),其具有三个主要部件:接线盒(10),其适于安装在天花板的开口内; 适于与接线盒(10)配合的盖(44); 以及包括用于处理由红外线传感器(42)产生的电信号并产生输出信号的红外传感器(42)和处理电路(45)的电子被动红外探测器子组件(43)。 盖(44)具有诸如适于安装到接线盒(10)的凸缘(48)的安装装置(或者如果不使用接线盒,则直接连接到天花板)和具有空腔的延伸部分(50) 52)和孔(46)。 盖(44)还具有穿过孔(46)定位的透镜阵列(36)。 电子被动红外检测器子组件43相对于盖44定位,使得当盖44被安装到接线盒10上时红外传感器42与透镜阵列36对准 ),使得所述红外传感器(42)从由所述透镜阵列(36)和所述红外线传感器(42)的并置限定的视野检测透过所述透镜阵列(36)的红外能量。
