Abstract: Embodiments relate to safing logic and fire set systems with a dual-mode pulse gate driver device and method of use. An aspect includes a device for a circuit having a switch, the device comprising: a gate driver including a trigger input to receive a trigger signal to initiate a test of the circuit in a first mode or a pulse through the circuit to cause a pyrotechnic chain reaction in a second mode, a power supply input and an output for driving the switch in response to receiving the signal. The device includes a trickle charge capacitor coupled to the power supply input. The device includes a high impedance coupled to the capacitor and input power circuitry, the high impedance trickle charging the capacitor and preventing a high voltage through the switch from being applied to the power circuitry in the first mode for subsequent operation in the second mode.

Abstract: Soft-switching gate control circuitry is disclosed. The circuitry includes a first discharge circuit coupled across a first switching device. A first control circuit, upon a first switch input signal transitioning from a disabled state to an enabled state, is adapted to cause the first discharge circuit to transition from a high impedance state to a discharge impedance state, and when a voltage across the first switching device drops below a first threshold value, cause the first switching device to transition from an off state to an on state.

Abstract: An accessory carrier assembly includes a reversible shank manufactured of a substantially square first portion and a substantially square second portion. The first portion is sized to engage a first hitch receiver and the second portion is sized to engage a second hitch receiver. To attach the accessory carrier to the reversible shank, the first segment is located in amounting assembly either with or without the bushings depending on which type of hitch receiver is available. The accessory carrier is pivotable by removal of a single pin to provide access to a rear of a vehicle. The single pin can be further located in a stop aperture to prevent overrotation of the carrier.
