Abstract: A transportable enclosure comprises a sheet of flexible material defining a closed loop, with the sheet defining an opening therethrough. The closed loop of the sheet is configured to be rotated by an actuator for selectively aligning the opening with an access position, such as a port in a side panel of a housing, for loading or unloading cargo from the interior space. A drive pulley is coupled to the actuator for rotating the sheet, and a belt extends along the closed loop to engage the drive pulley. The actuator may be located within the transportable enclosure or outside of the transportable enclosure. One or more guides are configured to hold the closed loop of the sheet outwardly while allowing the sheet to rotate. The transportable enclosure may be used with a ground or an aerial vehicle, which may be a vehicle configured for unmanned and/or autonomous operation.

Abstract: A transfer case for a four-wheel drive motor vehicle includes a two-speed range clutch unit, a mode clutch unit, a power-operated actuation mechanism and a control system. The actuation mechanism includes an electric motor, a geartrain driven by the motor for controlling rotation of an actuator shaft, a range actuator assembly and a mode actuator assembly. The range actuator assembly functions to move a shift collar associated with the range unit in response to rotation of the actuator shaft. The mode actuator assembly includes a mode cam and a ballramp unit. The mode cam is rotatively driven by the actuator shaft for controlling the clutch engagement force exerted on the friction clutch by the ballramp unit. The control system controls movement of the shift collar during motive operation of the motor vehicle to permit on-the-move range shifting.
