A device for examining a conveyor system having one or more motorized rollers comprises a measuring unit for determining a current profile of the motorized roller, wherein the measuring unit has a first interface and a second interface which are adapted to switch the measuring unit in the conveyor system between the motorized roller and a control unit controlling the motorized roller. A third interface is provided for receiving data on an operating situation present during the determination of the current profile. An evaluation unit is adapted to compare the determined current profile of the motorized roller with a reference profile which is characteristic for the operating situation.

A cargo handling system includes a conveyance surface; a first power drive unit having a first drive roller; a first restraint device; one or more sensors configured to provide positional data corresponding to a current location of a unit load device on the conveyance surface; and a first power drive unit agent configured for communication with the one or more sensors, the first power drive unit agent configured to selectively activate and deactivate the first drive roller and the first restraint device based on the positional data.

Various embodiments are directed to a diverter apparatus and method of using the same. In various embodiments, the diverter apparatus is configured to selectively direct an exemplary object traveling along a conveyor travel path to one of a plurality of adjacent conveyor locations. In various embodiments, the diverter apparatus may comprise a diverter conveyor surface, a cam follower, and a cam comprising a rotational range of motion about a cam shaft axis, the cam being physically engaged with the cam follower. Various embodiments are directed to a diverter apparatus configured to utilize a plurality of forces generated by the rotational motion of the cam to facilitate the transition of the directional configuration of the diverter conveyor surface from the first directional configuration to the second directional configuration, and, subsequently, from the second directional configuration back to the first directional configuration, again using the rotational motion of the cam.

A conveyor apparatus includes a drive unit, a connection interface which transmits analog signals, and a drive control module which is coupled to the drive unit and to the connection interface via signal technology. The drive control module receives analog control signals via the connection interface in an operating state and controls the drive unit as a function of the analog control signals, outputs digital diagnostic signals via the connection interface in a digital communication state, and switches from the operating state to the digital communication state upon receipt of a switchover command. The switchover command is made up of a predetermined analog control signal or a predetermined sequence of analog control signals.
