Abstract: An enrollment assistance device comprising a carrier with a first surface portion for a user device, and a second surface portion for a contactless smartcard; a first wireless power transfer arrangement supported by the carrier and arranged in the first surface portion of the carrier; a second wireless power transfer arrangement supported by the carrier and arranged in the second surface portion of the carrier; and a conductor arrangement supported by the carrier and conductively connecting the first wireless power transfer arrangement and the second wireless power transfer arrangement.

Abstract: The invention relates to an orbital welding device for mobile use in order to join a first pipe (1) and a second pipe end (2) along a circumferential joint (3) by at least one weld seam (4), particularly for producing a pipeline (5) to be placed on land. The inventive device includes a guide ring (6), which can be oriented toward the first pipe end (1) and the circumferential joint (3), and an orbital carriage (7) that can be motor-displaced along the guide ring (6) via an advancing device (8). On the orbital carriage (7), a laser welding head (12) for directing a laser beam (10) into a laser welding zone (13) is mounted in a manner that enables it to be oriented toward the circumferential joint (3) whereby enabling the production of the weld seam (4) along the circumferential joint (3) by displacing the orbital carriage (7).
