Abstract: A latch assembly may comprise: a housing; a pawl assembly coupled to the housing, the pawl assembly configured to transition from an un-restrained state to an restrained state; and a latch state detection system comprising a transducer and a communications module, the transducer configured to convert mechanical energy from the pawl assembly reaching the restrained state to an electrical energy configured to power the communications module.

Abstract: A mobile cargo controller for a cargo handling system is provided. The mobile cargo controller includes at least one inertial measurement unit configured to: identify a true forward position of a cargo compartment in which the cargo handling system operates, determine an orientation of the mobile cargo controller, and, using the true forward position of the cargo compartment and the orientation of the mobile cargo controller, identify a frame of reference for the mobile cargo controller within the cargo compartment.

Abstract: A convertible cargo handling system is provided. The convertible cargo handling system includes a roller tray mounting system and a first roller tray. The roller tray mounting system includes a sealing plate and a first floor fitting coupled to the sealing plate, where the first floor fitting is configured such that a top edge of the first floor fitting is flush with a surface of a floor. The first roller tray includes a first set of walls and a first roller tray fitting, where the first set of walls are configured to nest along sides of the first floor fitting below the surface of the floor and where the first roller tray fitting is configured to rest on the top edge of the first floor fitting.

Abstract: A above floor wiring system is disclosed herein. The above floor wiring system includes a tray including a sidewall, a wire bundle secured to the sidewall, and a junction card coupled to the sidewall and electrically coupled to the wire bundle.

Abstract: A quick attach splice is provided. The quick attach splice includes a first side rail, a second side rail parallel to the first side rail, a cross member extending from the first side rail to the second side rail, a first pin extending from within the cross member and through at least one of the first side rail or the second side rail, a tab configured to retract the first pin, and a roller extending from the first side rail to the second side rail.

Abstract: A tray connector is disclosed herein. The tray connector includes a first side rail, a second side rail, parallel to the first side rail, a cross member extending from the first side rail to the second side rail, a pin extending from within the cross member and through the first side rail, and a tab configured to retract the pin.

Abstract: A power drive unit for moving cargo relative to a cargo bay of an aircraft is disclosed herein. The power drive unit includes a lift cam coupled to camshaft, a drive wheel coupled to a drive shaft, and an induction motor having a first output shaft and a second output shaft, the first output shaft configured to drive the drive shaft and the second output shaft configured to drive the camshaft.

Abstract: A latch assembly may comprise: a housing; a pawl assembly coupled to the housing, the pawl assembly configured to transition from an un-restrained state to an restrained state; and a latch state detection system comprising a transducer and a communications module, the transducer configured to convert mechanical energy from the pawl assembly reaching the restrained state to an electrical energy configured to power the communications module.

Abstract: A power drive unit (PDU) for moving cargo relative to a cargo bay of an aircraft includes a cam shaft. The PDU also includes a lift cam coupled to the cam shaft and configured to cause the PDU to be in at least one of a raised position or a lowered position based on rotation of the cam shaft. The PDU also includes a permanent magnet motor configured to generate a cogging torque sufficient to resist rotation of the cam shaft such that the PDU remains in the raised position in response to power being removed from the permanent magnet motor.
