    • A transmitter produces a control signal which preferably has no DC component (i.e. its average magnitude is 0). The control signal is synchronized with an AC power signal on the AC power line and is embedded into it by summation to produce a modified AC power signal. A transmitter with an active load dropping circuit to provide a precisely shaped control signal is provided and a wave form with a small magnitude during the highest power portion of the AC power signal is provided, reducing the power consumption of the signalling system. A receiver calculates the area under each positive half wave of the modified power signal and compares it to a threshold to distinguish between "0" and "1" bits. In another embodiment, the receiver incorporates an asymmetric low pass filter. The filtered signal is attenuated (at a selected magnitude) when a "1" (or "0") bit is received. The receiver detects the attenuation by measuring the time for which the filtered signal exceeds the selected magnitude.
    • 发射机产生优选不具有直流分量(即其平均幅度为0)的控制信号。 控制信号与交流电源线上的交流电源信号同步,并通过求和将其嵌入到其中,以产生修改后的交流电源信号。 提供具有有源负载下降电路以提供精确调整的控制信号的发射机,并且在AC功率信号的最高功率部分期间提供具有小幅度的波形,从而降低了信号系统的功耗。 接收机计算修正功率信号的每个正半波下的面积,并将其与阈值进行比较,以区分“0”和“1”位。 在另一个实施例中,接收器包括非对称低通滤波器。 当接收到“1”(或“0”)位时,滤波后的信号被衰减(处于选定的幅度)。 接收机通过测量滤波信号超过选定幅度的时间来检测衰减。

    • An lighting energy management system and method for controlling lighting fixtures in a building, uses lighting fixtures, photo and occupancy sensors, personal lighting commands and an energy control unit. The energy control unit receives information from the photo and occupancy sensors and the personal controller and determines an optimal brightness command for each lighting fixture using a coordinated system of zone and fixture objects. Each zone object is associated with a building zone and each fixture object is associated with a light fixture. Each zone object ensures that lighting fixture lighting level is adjusted when a physical zone is unoccupied. Each fixture object uses sensors and personal inputs to determine a desired brightness level and uses a load shedding and daylight compensation to determine a daylight adjusted brightness level. The energy control unit determines an optimal brightness command based on these levels to minimize the energy required by the lighting fixtures.
    • 用于控制建筑物中的照明装置的照明能量管理系统和方法使用照明装置,照片和占用传感器,个人照明命令和能量控制单元。 能量控制单元接收来自照片和占用传感器以及个人控制器的信息,并使用区域和夹具对象的协调系统为每个照明装置确定最佳亮度命令。 每个区域对象与建筑物区域相关联,并且每个固定装置对象与灯具相关联。 每个区域对象确保在物理区域未被占用时调整照明灯具照明级别。 每个灯具对象使用传感器和个人输入来确定所需的亮度级别,并使用减载和日光补偿来确定日光调节后的亮度级别。 能源控制单元根据这些水平确定最佳亮度指令,以最大限度地减少照明灯具所需的能量。
