Abstract: A method of manufacturing a sealed circuit card assembly includes disposing a circuit card assembly within a volume defined by a housing and at least partially filling the volume with a curable liquid such that the curable liquid encapsulates at least a circuit card. The method may also include curing the curable liquid to form a potted circuit card assembly and, after at least partially filling the volume with the curable liquid and after curing the curable liquid, vacuum impregnating the potted circuit card assembly with a sealant to seal any exposed interfaces or cracks to form the sealed circuit card assembly. Accordingly, the sealed circuit card assembly may include a first cured material encapsulating the circuit card of the circuit card assembly and a second cured material disposed within, for example, a porosity of the first cured material.

Abstract: A brake system is disclosed herein. The brake system includes a motor, a hydraulic pump mechanically coupled to the motor, a directional control valve fluidly coupled to the hydraulic pump, and a brake assembly fluidly coupled to the directional control valve. The directional control valve is moveable between a braking position, in which the directional control valve allows hydraulic fluid to flow between the hydraulic pump and the brake assembly, and a parking position, in which the directional control valve prevents the hydraulic fluid from flowing between the hydraulic pump and the brake assembly.
