  • Publication number: 20080040618
    Abstract: The invention relates to a method for distributing content to a mobile device using a digital rights management (DRM) scheme, adapted for the case when files are exchanged over an external memory or over a serial connection between a computer (PC) and the mobile device, and a mobile device (ME) adapted therefor. The mobile device creates a request file (RORe-questrop) comprising information necessary for forming a rights object file. On the computer side, the request file is retrieved and a response file is sent back to the mobile device including the encrypted content (Contentdcf) and a rights object file (Content.ro). The mobile device receives the response file and decrypts and stores the content. The files may be exchanged over a DRM folder, arranged in the mobile device and accessible by the computer in mass storage mode, or the DRM folder may be arranged in an external memory (MS) alternately accessible by the mobile device and the computer.

  • Publication number: 20080004010
    Abstract: A method and arrangement for providing information to a client (200) from a client access network (202) regarding a requested set of users (204), at least some of which are connected to other access networks (206). In response to a client subscription request, the client access network establishes a network subscription with the other access networks. Information updates regarding users in the set are then continuously received and stored in a database (214) of the client access network, whenever the users change their state. In response to a subsequent request for user information from the client, corresponding stored user information is retrieved from the database and sent in a notification to the client.

  • Publication number: 20060243911
    Abstract: The present invention relates to apparatuses for use in performing a quantitative analysis of a turbid pharmaceutical sample, e.g. a tablet, a capsule or a similar sample forming a pharmaceutical dose. A pharmaceutical, turbid sample (24,57, 67) is irradiated with an excitation beam (20, 53, 64) of radiation, e.g. near infrared radiation. The intensity of emitted radiation (30) from the sample (24, 57, 67) is detected as function of both the wavelength of the emitted radiation and the photon propagation time through said sample (24, 57, 67). Optionally, the intensity of the emitted radiation (30) from the sample (24, 57, 67) is also detected in a spatially resolved manner.

  • Publication number: 20060246868
    Abstract: A first signal representation of one or more of the multiple channels is encoded (S1) in a first encoding process, and a second signal representation of one or more of the multiple channels is encoded (S2) in a second, filter-based encoding process. Filter smoothing can be used to reduce the effects of coding artifacts. However, conventional filter smoothing generally leads to a rather large performance reduction and is therefore not widely used. It has been recognized that coding artifacts are perceived as more annoying than temporary reduction in stereo width, and that they are especially annoying when the coding filter provides a poor estimate of the target signal; the poorer the estimate, the more disturbing artifacts. Therefore, signal-adaptive filter smoothing (S3) is introduced in the second encoding process or a corresponding decoding process as a new general concept for solving the problems of the prior art.

  • Publication number: 20060195314
    Abstract: The invention provides an efficient technique for encoding a multi-channel audio signal. The invention relies on the principle of encoding (S1) a signal representation of one or more of the multiple channels in a first encoding process, and encoding another signal representation of one or more channels in a second, filter-based encoding process. A basic idea according to the invention is to select (S2), for the second encoding process, a combination of i) frame division configuration of an overall encoding frame into a set of sub-frames, and ii) filter length for each sub-frame, according to a predetermined criterion. The second signal representation is then encoded (S3) in each sub-frame of the overall encoding frame according to the selected combination. The possibility to select frame division configuration and at the same time adjust the filter length for each sub-frame provides added degrees of freedom, and generally results in improved performance.

  • Publication number: 20060103567
    Abstract: A transmitting unit has a transmitter for transmitting signals of coded information about a position close to the unit in a space substantially unreachable by a satellite-based navigating system so as to provide a receiver arranged on a moving object present in said space with this position information for determining the position of the object. The transmitter is adapted to normally be in an inactive non-transmitting state, and the unit further comprises means adapted to detect movement of an object within a space and activate the transmitter to transmit signals only when movement of an object in the space is detected.

  • Patent number: 7037325
    Abstract: A distributor for a system for interactive interstitial photodynamic and photothermal tumor therapy and tumor diagnosis, comprises a plurality of primary radiation conductors arranged for conducting radiation to and from the tumor site, a plurality of secondary radiation conductors, two flat discs abutting against each other, wherein a first of said discs is fixed and the second of said discs is turnable relatively to the other disc, and each disc has holes arranged on a circular line. The proximal ends of the primary radiation conductors are fixed in the holes of the fixed disc and distal ends of the secondary radiation conductors are fixed in the holes of the turnable disc, whereby the primary and the secondary radiation conductors by rotation of the turnable disc are connectable to each other in different constellations.

  • Publication number: 20060053281
    Abstract: An existing communications device, such as a WAP-enabled mobile phone or other device, can be used as an authentication token. This has the advantage that WAP-enabled devices include components which are used in public key/private key cryptographic systems as a part of their standard communication functions. These components therefore advantageously allow the device to be used as an authentication token when communicating with a remote server.
