  • Publication number: 20120190338
    Abstract: A method for changing an operating mode of a mobile device is provided. According to the method, a request from the user of the mobile device to change from a first operating mode to a second operating mode is received. In response to the received request a credential is requested from the user. Next, the credential (RCK) is received from the user and validated. If the received credential (RCK) is valid, the second operating mode is set and an indication of the mobile device indicating that the second operating mode has been set is set. If the second operating mode has been set, a reset of the indication is prohibited.

  • Patent number: 8195945
    Abstract: A method for storing and updating digital certificates in a flash memory, a flash memory, and an electronic apparatus exploiting the method are disclosed. The method is applicable for a flash memory having predefined erase-write blocks and write-read blocks, for enhancing the tampering proof characteristics of the flash memory. The certificates may be used to authenticate a computer program and may be verified by a verification program associated with the computer program. The method may include defining a plurality of memory slots within at least one erased erase-write block wherein each memory slot have a commencing address comprising a binary “0”- or a binary “1” bit pattern, writing a first and second digital certificate in a first and second one of the memory slots, defining a certificate slot address pointer, and updating the certificate slot address pointer by replacing said “0”- or “1”-bit pattern of the pointer with a “1”- or a “0” bit pattern, respectively.

  • Publication number: 20120124653
    Abstract: A wireless communication device provides a method of certificate-based access control. Particularly, the device establishes a secure communications session with a device management server. Rather than use access control lists to control access to the functions and services on the device, however, the device uses the certificate that was employed to establish the secure session to control access.

  • Publication number: 20120104281
    Abstract: A method and system for luminescence molecular imaging or tomography of a region of interest in a scattering medium is disclosed. The system comprises a non-linear luminescent marker material arranged in the scattering medium. Contrast and resolution of the imaging or tomography is thus improved. The non-linear marker is for instance configured to upconvert incoming light of an illumination wavelength. The non-linear power dependence of the marker enables further improvement of the imaging by using images taken with two or more excitation beams simultaneously.

  • Patent number: 8165299
    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.

  • Publication number: 20120032377
    Abstract: Method, apparatus and stamp for aligning a first surface (11) of a first object (10) with a second surface (22) of a second object (20), facing said first surface, wherein light of a predetermined wavelength is introduced into one (10) of said objects and caused to propagate by internal reflection therein. The first and second surfaces carry correlating structures (13,25) which, when arranged at close distance from each other, couple light from said one object to the other of said objects by near-field tunneling, to a degree dependent on the overlap of said structures. A light detector (26) is devised to detect a signal which is dependent on the amount of light coupled between said objects, for producing an alignment control signal. The invention is suitable for use in nanoimprint lithography.

  • Publication number: 20110316260
    Abstract: An attachment bracket for fastening an airbag to a vehicle structure includes an opening into which a strap connected to the airbag can be inserted, and a clamping surface provided for resting against the vehicle structure. The attachment bracket is formed from at least a first layer forming the clamping surface and a second layer spaced from the first layer in a spring elastic manner. The first and the second layers can be located on the same side of the vehicle structure. The attachment bracket can be fastened to the vehicle structure by a fastening means. The distance between the first and the second layer can be reduced by fastening the attachment bracket with the fastening means. A clamping force acting between the first layer and the vehicle structure can be generated by reducing the distance.

  • Publication number: 20110185434
    Abstract: A method and a filter element for preventing scraping/clipping of the information content of a database used for providing a website with data information. When a data record set from the database has been received, the filter splits all elements/fields of the data record set in a predetermined way into cells and a sortid is provided. Each cell is encoded into a markup language, wherein location information in the cell is used for generating a location value. The encoded cells are sorted into a file to establish a file, e.g. web page, wherein the encoded data cells are distributed in an arbitrary order.

  • Patent number: 7945055
    Abstract: A first signal representation of one or more of the multiple channels is encoded in a first encoding process, and a second signal representation of one or more of the multiple channels is encoded 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 is introduced in the second encoding process or a corresponding decoding process.

  • Patent number: 7945250
    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.
