  • Patent number: 7455316
    Abstract: An air-bag arrangement is disclosed which comprises an air-bag (21), an aperture (22) communicating with the interior of the air-bag (21), and a gas generator (23) to generate gas to inflate the air-bag (21). The gas generator (23) is mounted for pivotal movement about a pivot axis extending across the aperture (22) so that the gas generator (23) is pivotally moveable between a closed position in which at least part of the gas generator (23) extends across the aperture (22), to close the aperture (22), and an open position in which said aperture (22) is opened to permit the flow of gas from the air-bag (21).

  • Publication number: 20080262850
    Abstract: The invention provides a highly efficient technique for encoding a multi-channel audio signal. The invention relies on the basic principle of encoding a first signal representation of one or more of the multiple channels in a first encoder (130) and encoding a second signal representation of one or more of the multiple channels in a second, multi-stage, encoder (140). This procedure is significantly enhanced by providing a controller (150) for adaptively allocating a number of encoding bits among the different encoding stages of the second, multi-stage, encoder (140) in dependence on multi-channel audio signal characteristics.

  • Publication number: 20080244685
    Abstract: Methods and devices provide dynamic security management in an apparatus, such as a mobile telephone terminal. The apparatus includes a platform for running an application; a security manager for handling access of the application to functions existing in the apparatus; an application interface (API) between the platform and the application; a set of access permissions stored in the apparatus and used by the security manager for controlling access of the application to functions through the application interface. Methods can include downloading into the apparatus an object containing access permissions applicable to at least one function; verifying the object; and installing the access permissions together with the existing permissions.

  • Patent number: 7393010
    Abstract: An air-bag arrangement includes an air-bag and a gas generator to supply gas to inflate the air-bag. The gas generator is hingedly connected to a support and is hingedly movable between a closed position in which the gas generator extends across and closes an aperture, and a second position in which the apertured is opened to permit the flow of gas from the air-bag. The gas generator is initially retained in position by a retainer the retainer being actuable, in response to a signal, to enable the gas generator to move hingedly to the open position.

  • 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.
