Abstract: Embodiments are directed to a blade lock comprising a fold lock adapted to prevent folding of a rotor blade in a fold-lock position and to allow folding of the rotor blade in a pitch-lock position. The blade lock further comprises a pitch lock adapted to allow pitch movement of a rotor blade in a fold-lock position and to prevent pitch movement of the rotor blade in the pitch-lock position. A spring-loaded link pivotally connects both the fold lock and the pitch lock and is adapted to provide passive, overcenter locking in the fold-lock position. An actuator is coupled to the pitch lock and is adapted to move the pitch lock and the fold lock between the fold-lock and pitch-lock positions.

Abstract: In an embodiment, a battery connector includes: power terminals configured to be coupled to a load having an input capacitance; power pins electrically coupled to the power terminals; a charge pin, the charge pin being longer than each of the power pins; and an antispark circuit electrically interposed between the charge pin and the power terminals, the antispark circuit including: a dissipation circuit configured to charge the input capacitance of the load in response to a battery being coupled to the charge pin; and a delay circuit configured to delay charging of the input capacitance of the load for a predetermined duration after the battery is coupled to the charge pin.
