Abstract: Bandwidth use between an access provider system (14) and a user computer (10) is adapted to an amount of subscription quotum that has been used by a subscriber. Quotum use information is representative of an amount of data that has been exchanged between the user computer (10) and an access provider system (14) since a predetermined time point. A request is received for retrieving media information from the network (16) and for rendering that media information at the user computer (10). In response to the request a selection is made between a plurality of versions of the requested media information, dependent on the quotum use information. Different versions require respective different data rates for transmission from the access provider system (14) to the user computer (10). The more quotum has been used, the lower the data rate of the selected version.

Abstract: The present invention relates to a magnetic resonance imaging (MRI) device and to a method for operating it. The basic components of an MRI device are the main magnet system (2) for generating a steady magnetic field, the gradient system (3) with at least one gradient coil, the RF system and the signal processing system. According to the present invention, the gradient coil is split into sub-coils (S1, S2) at least in the direction of the steady magnetic field. By doing so, the amplitude of the non-imaging component of the gradient field in the vicinity of the patient is reduced, leading to reduced peripheral nerve stimulation and thus enhanced image quality.

Abstract: A fast method for allocating those channels or subcarriers of a multicarrier network to an ahead lying transmission is to let a transmitting terminal and a receiving terminal which intend to access the medium determine the status of the channels or subcarriers that are within their reception range and send a signal indicating the determined status to the corresponding terminal which will select those channels or subcarriers for the eventual transmission which fit best. Other terminals within the transmission range of the transmitting or the receiving terminal respect the reservation and wait for the current transmission to find out which channels or subcarriers are actually used.

Abstract: A method is described for recording information on a multi-layered optical disc (2), the disc comprising two storage spaces (LO, L1) in adjacent storage layers (40, 41). Data to be recorded are received from a source. On recording, the data are organized to form cells (35), each cell corresponding to a certain amount of data. The cells are first recorded in the first storage space (LO) until the last storage address (N) of the first storage space, and then the recording process makes a transition to the first storage address (N+1) of the second storage space. The size of the last cell to be recorded in the first storage space is determined in relationship to the size of the remainder part (R) of the first storage space, such that the transition from the first storage space to the second storage space corresponds to a cell boundary (34).
