摘要： Identifying periodic jitter in a signal includes identifying transition regions of the signal, where the transition regions correspond to regions of the signal where the signal changes between different levels, determining lengths of the transition regions; and performing a statistical analysis that is based on the lengths of the transition regions in order to obtain a value indicative of a level of periodic jitter in the signal.

摘要： The invention is a control system for the emergency jettison of a cargo container extraction parachute from a cargo container within an aircraft, the aircraft having a plurality of cargo containers onboard that are ejectable in sequence. In detail, the system includes a load transfer coupling coupled to each extraction parachute for releasing the extraction chute from the cargo container upon receipt of electrical power. A first circuit is coupled to the load transfer coupling, the first circuit for providing the electrical power to the load transfer coupling of the next ejectable cargo container upon receiving an actuation signal to release the extraction parachute. A second circuit is used to sense when each of the plurality of cargo containers has been ejected from the aircraft and to provide the cargo container ejection signal to the first circuit upon the cargo container being ejected from the aircraft. The actuation signal is provided to the first circuit if the ejection signal is not received within a specific time after initiation of the cargo ejection sequence. A third circuit is used to manually provide the actuation signal to the first circuit providing immediate jettison of the extraction parachute.
摘要翻译： 本发明是一种用于从飞机内的货物集装箱紧急排放货物集装箱提取降落伞的控制系统，该飞行器具有能够按顺序排出的多个在船上的货物集装箱。 详细地，系统包括联接到每个提升降落伞的负载传递联轴器，用于在接收到电力时从货物集装箱释放提取槽。 第一电路耦合到负载传递联接器，第一电路用于在接收到致动信号以释放提取降落伞时将电力提供给下一个可喷射货物集装箱的负载传递联接。 第二电路用于感测多个货物集装箱中的每一个是否已经从飞行器弹出并且在货物集装箱从飞机上弹出时将货物集装箱弹出信号提供给第一回路。 如果在开始货物喷射顺序之后的特定时间内没有接收到喷射信号，则致动信号被提供给第一回路。 第三电路用于手动地向第一电路提供致动信号，从而提供提取降落伞的即时喷射。
