    • Disclosed is a drain blockage responsive alarm system. The drain blockage responsive alarm system comprises a cleanout cap member, at least one drain blockage responsive element, and an alarming module. The cleanout cap member is capable of being installed at a portion of a drain pipe. Further, the at least one drain blockage responsive element is configured to the cleanout cap member adapted to sense clog deposition at the portion of the drain pipe, and to generate an output signal upon sensing the clog deposition. Furthermore, the alarming module is electrically coupled to the at least one drain blockage responsive element for generating an alarm signal upon receiving the output signal.
    • 泄漏阻塞响应报警系统。 排水阻塞响应报警系统包括清洁盖构件,至少一个排水堵塞响应元件和报警模块。 清洁盖构件能够安装在排水管的一部分。 此外,至少一个排水堵塞响应元件构造成适于感测排水管部分处的堵塞沉积的清洁盖构件,并且在感测堵塞沉积时产生输出信号。 此外,警报模块电耦合到至少一个漏极阻塞响应元件,用于在接收到输出信号时产生报警信号。

    • A wheelchair assembly for propelling a wheelchair is provided. The wheelchair has front wheels and rear wheels and a pair of armrests. The wheelchair assembly comprises a first gear wheel secured to each rear wheel and a second gear wheel secured to each armrest. The second gear wheel is positioned directly over the first gear wheel with the second gear wheel being completely encased by a cover. A chain is secured over and between the first and second gear wheels and extends from an opening in the cover. Rotatable handles are attached to each armrest with each having a grasping portion extending Upward. A control linkage extends between the handles and the second gear wheels and mounted to and under the armrest such that rotation of the handles also rotates the second gear wheels with the control linkage being perpendicular to the line formed between the first and second gear wheels.
    • 提供用于推动轮椅的轮椅组件。 轮椅有前轮和后轮以及一对扶手。 轮椅组件包括固定到每个后轮的第一齿轮和固定到每个扶手的第二齿轮。 第二齿轮直接位于第一齿轮上方,第二齿轮被盖完全包围。 链条固定在第一和第二齿轮之间并且在第一和第二齿轮之间并且从盖的开口延伸。 可旋转手柄连接到每个扶手上,每个扶手具有向上延伸的抓握部分。 控制联动装置在手柄和第二齿轮之间延伸并安装在扶手上和下面,使得手柄的旋转也使第二齿轮旋转,控制联动装置垂直于形成在第一和第二齿轮之间的线。
