A system and method are provided to employ a profiling infrastructure to perform profiling. One arrangement includes a first camera for taking a video image of the presenter, mounted on the cart, and a second camera, mounted on the cart, for taking images of documents. A maximum horizontal extension of the field electrode in a measure plane parallel to a first surface of the semiconductor body is at most 500 nm. The logical layer determines an offset into the buffer based on a length of a physical header written by the physical layer and writes data to the buffer from the determined offset. The method allows a subscriber side network terminal to receive from a locally attached computer an IP address request in a wide area network compatible format and to obtain from a remote server an IP address using a local area network compatible request.
