    Abstract: Aspects of this disclosure relate to a miniaturized digital radar system and method that can be fabricated on a Printed Circuit Board (PCB) and/or a chip, such as on a System-On-a-Chip (SOC). The digital radar system can operate at the S-band (e.g. in the range of 3 GHz). Advantageously, the S-band frequency range is less susceptible and/or not susceptible to clutter from precipitation and is well suited for long range surveillance applications. The small form factor of the miniaturized digital radar system on the PCB and/or the SOC can be implemented on small and/or low-observable platforms, such as on fixed or rotary wing unmanned aerial vehicles.

    Abstract: In some implementations, a conductive concrete composition for providing improved shielding against electromagnetic radiation comprises cement, one or more supplementary materials, aggregates, one or more carbon products, and fibers. In some implementations, the composition comprises between about 5% and about 40% by weight of cement, between about 1% and about 20% by weight of one or more supplementary materials, between about 5% and about 80% by weight of aggregates, between about 1% and about 40% by weight of one or more carbon products, and between about 1% and about 10% by weight of fibers. In some embodiments, the one or more supplementary materials comprises ground granulated blast furnace slag (GGBS), the one or more carbon products comprises graphite, and the fibers comprise steel fibers. The aggregates can include normal weight, lightweight, and/or fine aggregates.

    Abstract: 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.

    Abstract translation: 包括浮球，杆，套筒，指示盘和发电机电路的系统提供关于水箱中的水位的信息，以及流体是否流入罐中。 该杆在套筒内滑过罐体上方的板坯。 杆的第一端由浮球支撑，浮球浮在水箱内，而杆的第二端位于板的上方并支撑指示盘。 用户可以根据指示盘的高度来检测油箱中的水位。 用户还可以检测水是否流入水箱。 当水流入水箱时，发电机电路激活位于指示盘上的LED。
