Various embodiments include methods and systems for a cloud enabled virtual gateway. The system comprises an evaluation unit and a roll-of device, which contains a first spindle for the rotatable seating of the first gear wheel, a second spindle for the rotatable seating of the second gear wheel and a drive mechanism for rotating the first gear wheel and a drive mechanism for acting with a positive or a negative torque on the second gear wheel. A first tool has waste stripping needles protruding radially outward from the outer surface. Customer relationship management information associated with the user of the client device is received from a carrier system associated with the client device. By forming the gate-to-body contact structure that can reduce the gate-to-body contact resistance and increase the device packing density, the DTFET can be used in silicon on insulator technologies and take full advantages of the DT-CMOS performance benefit.
