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).

Abstract: The present invention relates to a system and a method of verifying the identity of a user and based thereon controlling access to user specific data or actions, said method verifies said identity by receiving an identification key, and based on a comparison with a pre stored reference identification key access to said user specific data or action is controlled, said identification key being obtained by the steps of: visually recording a gesture by recording the trajectory of a hand of said user when the user uses said hand for performing a gesture, extracting gesture characteristics from said visually recorded gesture, performing said verification by comparing an identification key comprising said gesture characteristics with a pre stored reference identification key comprising reference gesture characteristics. An advantage of the gesture signature over “static” approaches like iris scans or face recognition is reliability.

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: After an update of an optical drive with a new firmware or after any other event that changed content of non-volatile memory means of the optical drive it is possible that the user for any reason wants to restore the original operational condition of the optical drive. However, even after a re-flash with the old firmware there may arise the problem, that the original operational condition is not successfully restored. This in many cases is due to the fact, that a new firmware can also reprogram other programmable content in the optical drive which remains in the updated state, even after a re-flash. In accordance with the present invention the possibility to successfully restore the original operational condition is provided by storing all restore information necessary to restore the original operational condition on a storage medium, particularly a flash-disk, before an update/change is made.

Abstract: The present invention relates to an optically pumped waveguide laser (2) comprising a waveguide with an optical propagation layer (3, 4) and two resonator mirrors (6, 7). The propagation layer (3, 4) consists of a gain medium at least along a section of said waveguide, said gain medium allowing up-conversion or down-conversion of incident pump light. One of the resonator mirrors is at least partially transparent to the pump light so as to allow end-pumping of the waveguide laser through a first end face (8) of the waveguide. The propagation layer (3, 4) has a geometrical width which is reduced in a first section of the waveguide, starting from the first end face (8) towards a second end face (9), thereby increasing an energy density of the incident pump light when propagating in the first section towards the second end face (9).
