摘要： A system including a float ball, a pole, a sleeve, an indicator disk, and a dynamo circuit provides information regarding the water level in a tank, and whether fluid is flowing into the tank. The pole slides within the sleeve, through a slab above the tank. A first end of the pole is supported by the float ball, which floats within the tank, while the second end of the pole is located above the slab and supports the indicator disk. A user can detect the water level in the tank based on the height of the indicator disk. A user can also detect whether water is flowing into the tank. The dynamo circuit activates an LED located on the indicator disk when water is flowing into the tank.

摘要： The Qibla orientation device is a small, hands-free device enabling a user of the device to determine Qibla, or the proper orientation to face the Kaaba in Mecca. The device contains a GPS receiver, magnetic direction sensor, directional indicator lights, audio directional output, and a longitudinally aligned laser projector. The device determines its position on the surface of the earth by the GPS receiver, and its orientation toward the Kaaba according to the location determined and the magnetic direction sensor. Directional lights are provided to orient the user to the left or right for alignment. Audio output is also provided for the visually handicapped. The laser may be activated to project a laser line aligned with the longitudinal axis of the device for determining orientation during initial construction of a mosque or other structure.
摘要翻译： Qibla定向设备是一种小型免提设备，可让设备的用户确定Qibla，或者正确的方向面向麦加的Kaaba。该设备包含GPS接收器，磁性方向传感器，方向指示灯，音频方向输出和纵向排列的激光投影仪。该装置通过GPS接收器确定其在地球表面上的位置，并根据所确定的位置和朝向Kaaba的方向确定磁方向传感器。提供定向灯以使用户向左或向右定向以进行对准。还为视障人士提供音频输出。激光器可以被激活以投影与装置的纵向轴线对齐的激光线，以便在清真寺或其他结构的初始构造期间确定取向。
