Abstract: An interface system for a portable structure, at least one power supply, at least one wired functional device, and at least one wireless functional device. A power interface is operatively connected to the at least one power supply. A wired interface is operatively connected to the at least one wired functional device. A wireless interface is wirelessly connected to the at least one wireless functional device. A controller is operatively connected to the power interface, the wired interface, and the wireless interface. The controller controls the power interface to distribute power from the at least one power supply to the at least one wired functional device. The controller controls the wired interface to distribute at least one of commands and data to the wired functional device. The controller controls the wireless interface to distribute at least one of commands and data to the wireless functional device.

Abstract: A portable power supply adapted to be connected to an external power source and to an electronic device comprises a main module comprising a battery, a satellite module comprising an input port, and output port, and an interface panel, and a tether cable, and a controller. The controller a first mode to allow the battery to be charged when the external power supply is connected to the input port, a second mode to allow power to be supplied to the electronic device from the battery when the electronic device is connected to the output port, and a third mode to allow the battery to be charged and power to be supplied to the electronic device when the external power supply is connected to the input port and the electronic device is connected to the output port.

Abstract: An auxiliary system for operating at least one motor operatively connected to first and second legs of a 5th Wheel RV comprising a calibration system that stores level position angular displacement data when the 5th Wheel RV is in a substantially level position and disconnect position angular displacement data when the 5th Wheel RV is in a disconnect position, a disconnect system stores pre-disconnect position angular displacement data immediately prior to disconnection of the 5th Wheel RV from the vehicle and operates the first and second motors based on the disconnect position angular displacement data and pre-disconnect position angular displacement data to displace the 5th Wheel RV to allow the 5th Wheel RV to be detached, and a leveling system operates the first and optionally second motors based on the level position angular displacement data to place the 5th Wheel RV in a substantially level position.

Abstract: A computerized control system for automating the process of connecting, disconnecting and leveling a fifth wheel RV. This system replaces the manually operated up/down pushbutton switches that control the movement of the motorized supports legs at the front of the RV. It is connected to the RV's battery and support legs motor. When it is time to disconnect the fifth wheel tow vehicle from the RV, the user presses the “Disconnect” button. The system automatically moves the RV's support legs down until it detects that the RV is at the disconnect position and then stops. The user can then disconnect the fifth wheel normally. When it is time to level the RV, the user presses the “Auto Level” button and the system automatically lowers the RV to a level position. When it is time to reconnect the RV to the truck, the user presses the “Connect” button and the system automatically raises the RV back to the exact same height as before it was disconnected.
