摘要： A power distribution system includes a plurality of power sources and load transfer units including transistors and diodes connected in series and leading to a common power output, each of the transistors being controller switchable subject to voltage levels of the respective input and output sides of said transistors, and the voltage and current level of said common power output. The system is part of an interconnection scheme in which all but one of the power sources is connected to a single load transfer unit, enabling the survival of at least a single power source with the failure of one of the load transfer units.

摘要： A solid state power controller is automatically reset if an overload trip occurs during a start-up delay period. If an overload trip occurs during load starting, the SSPC remains tripped for a reset delay period, and thereafter the SSPC is automatically reset, thereby allowing the starting process to continue by heating a lamp filament, accelerating a motor, etc., without indicating a system fault to an operator. At the expiration of the start-up delay period, the SSPC no longer automatically resets in response to an overload condition.
摘要翻译：如果在启动延迟期间发生过载跳闸，固态功率控制器将自动复位。如果在负载启动期间发生过载跳闸，SSPC将保持跳闸复位延迟时间，此后SSPC自动复位，从而允许启动过程继续加热灯丝，加速电机等，而不指示系统故障。在启动延迟时间到期时，SSPC不再响应于过载条件自动复位。

摘要： An electrostatic discharge system for neutralizing the charge accumulated an aircraft utilizes a pair of unequal length probes to sense the intensity of the external electric field. A transformer arrangement energizes these probes with out-of-phase voltages such that the corona currents flow in opposite directions through these probes. The dual probe configuration eliminates any errors due to environmental changes, while the out-of-phase excitation mode allows the AC component of the output signal to be canceled at a load resistor in the sensor circuit by a subtractive process, a feature which greatly simplifies the filtering operation.
摘要翻译：用于中和飞机上累积的电荷的静电放电系统利用一对不等长的探头来感测外部电场的强度。变压器布置使这些探针以异相电压激励，使得电晕电流通过这些探针在相反方向流动。双探头配置消除了由于环境变化引起的任何错误，而异相激励模式允许输出信号的交流分量通过减法处理在传感器电路中的负载电阻上消除，这一特点大大简化了过滤操作。

摘要： A connecting assembly interconnects one fiber optic cable harness to another fiber optic cable harness, or to an electronic unit containing an optical transmitter or receiver. The backshell includes a coupling ring that prevents loosening of the connection without first relaxing tension on the individual fiber optic cables in the cable harness. The inability to rotate the connector end coupling ring before relaxing tension on the fiber optic cables prevents damage to the individual fiber optic cables from occurring when the backshell is rotated with respect to the connector.

摘要： In response to the loss of a generator in an electrical power system, all operating electrical loads are automatically switched to a second generator, and the electric power system continues to provide power to all of the loads. The total power required to operate all operating loads is permitted to exceed the nominal rated capacity of the operating generator, and the winding temperature or other critical hotspot temperature of the operating generator is monitored to determine whether thermal stress limits will be exceeded. If the critical hotspot temperature approaches the thermal stress limit, certain electrical loads are disconnected via a pre-programmed load shed priority schedule, and thereafter loads are re-connected as other loads are de-energized or if the critical hotspot temperature decreases.
