    • An improved faucet control system for reducing water and energy usage in manual washing operations. The faucet control system has a foot pedal that controls the flow of water without the need of operating the faucet. The foot pedal, upon alternate activations, reverses the polarity of an electrical output pulse to the at least one latching solenoid valve, whereby flow through the faucet is controlled in an on/off fashion. At least one battery is present as a power supply and the system consists of at least one latching solenoid valve in at least one faucet supply line.
    • 改进的水龙头控制系统,用于减少手动洗涤操作中的水和能源消耗。 水龙头控制系统具有脚踏踏板,无需操作水龙头即可控制水流。 脚踏板在交替激活时将电输出脉冲的极性反转到至少一个闭锁电磁阀,由此通过水龙头的流量以开/关方式被控制。 至少一个电池作为电源存在,并且系统由至少一个水龙头供应管线中的至少一个闭锁电磁阀组成。

    • A test system couples various ports of one or more CPE devices to components mounted in a rigid mounting system. The system can test the line card portion of the CPE devices coupled to line card interface equipment for various parameters. Variable RF attenuation in RF interface equipment can adjust power levels to/from the RF port of the CPE devices to account for close proximity and variations between different vendors and models, which are coupled via the RF interface equipment to an included CMTS. Network interface equipment tests network port performance of the CPE devices by coupling a general purpose computer thereto. Switching one of a plurality of CPE devices to be the only one tested at a time and switching an addition RENLOAD is controlled by a provisioning server based on criteria including information in a database of various parameters of the particular device being tested.
    • 测试系统将一个或多个CPE设备的各个端口耦合到安装在刚性安装系统中的组件。 系统可以测试与线路卡接口设备耦合的CPE设备的线路卡部分的各种参数。 RF接口设备中的可变RF衰减可以调整到CPE设备的RF端口的功率水平,以考虑到通过RF接口设备耦合到所包含的CMTS的不同供应商和型号之间的近距离和变化。 网络接口设备通过将通用计算机耦合到CPE设备来测试网络端口性能。 将多个CPE设备中的一个切换为唯一一次被测试并且切换附加RENLOAD的设备由供应服务器基于包括被测试的特定设备的各种参数的数据库中的信息的标准来控制。
