Abstract: The system for a collapsible direction finding antenna. The antenna comprising a rigid central portion and a plurality of foldable arms. The antenna is aerial/kite lifted once launched from a tube to provide increased line of sight above a surface. The antennas being launchable from a UUV, a user in the field, and the like. The antenna being a full azimuth direction finding antenna. In some cases, operating at a wide matched frequency of 1 to 6 GHz.

Abstract: A dual path ring oscillator core includes three dual path inverters, each having a first inverter and a second inverter. Within the first inverter, one transistor is coupled to a first output of a previous dual path inverter, while another transistor is coupled to a second output of the previous dual path inverter. Within the second inverter, one transistor is coupled to the second output of the previous dual path inverter, while another transistor is coupled to the previous dual path inverter's first output. A first and a final dual path inverter are analogously coupled. A transient pulse will not propagate through successive dual path inverter stages. A dual to single path converter is coupled to receive signals output by the final dual path inverter. If a transient signal appears at a dual to single path converter input, stray output node capacitance maintains a correct output signal value.
Abstract translation: 双路环形振荡器芯包括三个双路径反相器,每个具有第一反相器和第二反相器。 在第一反相器内,一个晶体管耦合到先前的双路反相器的第一输出,而另一个晶体管耦合到先前的双路径反相器的第二输出端。 在第二反相器内,一个晶体管耦合到先前的双路反相器的第二输出,而另一个晶体管耦合到先前的双路反相器的第一输出。 类似地,第一和最终双路反相器耦合。 瞬态脉冲不会通过连续的双路径反相器级传播。 双路到单路转换器被耦合以接收由最终双路径反相器输出的信号。 如果瞬态信号出现在双通道到单通道转换器输入端,杂散输出节点电容保持正确的输出信号值。

Abstract: The system and method of retractable solar arrays for underwater vehicles. In some cases, the retractable solar arrays for underwater vehicles contain anti-biofouling mechanisms. The retractable solar arrays may extend in a linear or a fan-like manner. In some cases, the solar array may be wrapped around the outside of the underwater vehicle or within a cylindrical housing. In some cases the solar array is a single flexible member with a series of connected panels.

Abstract: A system and method for metadata processing that can be used to encode an arbitrary number of security policies for code running on a stored-program processor. This disclosure adds metadata to every word in the system and adds a metadata processing unit that works in parallel with data flow to enforce an arbitrary set of policies, such that metadata is unbounded and software programmable to be applicable to a wide range of metadata processing policies. This instant disclosure is applicable to a wide range of uses including safety, security, and synchronization.
