Abstract: A method of encoding a video sequence comprising Reference Picture Sets (RPSs) is provided. The method comprises arranging the RPSs in transmission order in a data structure, such as a Sequence Parameter Set (SPS), determining whether explicit RPS transmission is used for an RPS of a current picture of the video sequence, and encoding information indicating an RPS comprised in the data structure to be used for predicting the RPS of the current picture, such as delta_idx_minus1, only if explicit RPS transmission is used. By transmitting delta_idx_minus1 only if explicit RPS transmission is used, and interpreting delta_idx_minus1 to be equal to zero otherwise, a reduced bitrate is achieved. Further, a method of decoding a video sequence comprising RPSs, corresponding computer programs and computer program products, as well as corresponding encoders and decoders are provided.

Abstract: The embodiments of the present invention relate to compression of parameters of an encoded texture block such that an efficient encoding is achieved. Index data is used as an example of parameters to be encoded. Accordingly, encoding the index data is achieved by predicting the index data, wherein the prediction is done in the pixel color domain, where changes often are smooth, instead of in the pixel index domain where the changes vary a lot. Hence, according to embodiments of the present invention the index data is predicted from previously predicted neighboring pixels taking into account that the base value and a modifier table value are known. When the index value is predicted the real index value can be decoded with the prediction as an aid. Since this way of predicting the index provides a very good prediction, it lowers the number of bits needed to represent the pixel index.

Abstract: A skin retention device 10 for a medical jet-injection unit 20 having a contact face provided with adhesive 12 in the area surrounding and close to the injection opening(s) 11 of the nozzle 21 which ensures good contact between the nozzle 21 and the skin 30 of a subject in the area chosen for an injection. The injection force can be lowered dramatically. In case of two-stage jet-injections, the initial injection force can be lowered because the skin retention close to the injection point significantly reduces the energy consuming elastic expansion of the skin 30 in the injection area, and the second injection force can be lowered because of the high degree of fixed positioning of the injection opening of the nozzle 21 relative to the injection channel in the skin 30 made during the initial injection stage.

Abstract: First and second codewords are determined, based on first feature vector components of the image elements in an image block, as representations of a first and second component value. Third and fourth codewords are determined, based on second vector components, as representations of a third and fourth component value. First N1 and second N2 resolution numbers are selected based on the relation of a distribution of the first vector components and a distribution of the second vector components. N1 additional component values are generated based on the first and second component values and N2 additional component values are generated based on the third and fourth component values. Component indices indicative of the generated component values are then provided for the different image elements.

Abstract: The embodiments of the present invention reduce the compression time in order to achieve a faster texture compression. That is achieved by guessing, i.e. estimating the best table or tables (e.g. from tables 0 to 7) representing luminance information, and to only execute the compression for the table(s) estimated to provide the best luminance information.

Abstract: A pressurized injection device comprises a mechanical loading mechanism comprising a double set of rackets (17,18) and ball bearings/pins running in a curved track (20) which enables a resilient element (7) to be pre-stressed by—twisting the two outer house parts of the device relative to each other back and forth. When twisted in one direction one set of rackets (17) engages the teeth of the piston rod (9) connected to the resilient element and when twisted in the opposite direction, the other set of rackets (18) engages same piston rod. The resilient element is set off to engage a plunger of a container holding a drug to be injected by pressing the release button (1), which can be secured by a safety switch.

Abstract: An arrangement and method in a wireless communication network provides users with full control of service management, defines how a user can enter or leave services, and defines dependencies between services. A mobile terminal initiates establishment of a group and creates a unique groupID. The terminal sends invitations to other terminals to join the group and includes the unique groupID and a service feature tag for a desired service. The terminal will not request a service if it is incompatible with a service already running. Terminals that receive invitations store the groupID and service feature tags. These parameters are used to send acceptances or rejections, and to join later or leave a service.

Abstract: The invention provides a jet expelling assembly comprising a reservoir and an impulse chamber assembly. The impulse chamber assembly comprises a chamber portion defining a cavity having a general axis, a piston received in the cavity along the general axis and comprising a fluid inlet, thereby defining a variable-volume impulse chamber with an outlet nozzle. The inlet comprises a conduit adapted to slidably engage a reservoir outlet during relative movement therebetween. The chamber portion is arranged stationary relative to the reservoir, whereby expelling an amount of drug from the reservoir to the impulse chamber via the inlet causes the piston to move towards the reservoir, the impulse chamber thereby receiving the expelled amount of drug.

Abstract: A method of retrieving information comprised in a barcode is disclosed. The method comprises detecting that the barcode is present in a first image having a first image quality and capturing a first region, acquiring, when it is detected that the barcode is present, a second image having a second image quality and capturing a second region, wherein the second image quality is higher than the first image quality, and wherein the second region at least partly overlaps the first region, and decoding the barcode based on the second image to retrieve the information.

Abstract: An image (1) is decomposed into multiple superblocks (20, 22), each encompassing multiple pixel blocks (30A-30D, 32A-32D) having multiple pixels (40). The property values of a superblock (20) is fixed rate compressed to get a compressed block having a target bit length. The compressed block is stored in the memory locations (310, 320) assigned to the multiple pixel blocks (30A-30D) encompassed by the superblock (20) to thereby get multiple copies of the compressed block in the memory (300). The multiple copies collectively constitute a compressed representation of the superblock (20). When accessing a compressed block in a memory location (310) using random access during decoding, property values for neighboring pixel blocks (30B-30D) are obtained for free without the need for any further memory access.

Abstract: A block of image elements is compressed by determining a parameter representative of a size of a bounding section in vector space encompassing feature vectors associated with the image elements. This size parameter is used to provide a deterministic, pseudo-random pattern of multiple representation vectors encompassed by the bounding section. A vector among multiple representation vectors is selected as representation of the feature vector of an image element. An identifier associated with selected vector is assigned to the image element and included in the compressed block which also comprises representations of the size parameter.

The reference may also be added as an a-line augmenting an m-line in a Session Description Protocol (SDP) part of the SIP message.

Abstract: Multi-mode decoding and encoding of texture blocks are disclosed wherein in a default decoding and encoding mode all bits of a codeword sequence are available as payload bits for representing texel values of the texels in the texture block. In an auxiliary encoding and decoding mode one less bit of the codeword sequence is available as payload bits. The auxiliary mode is employed as a complement to the default mode and will be used to process those texture blocks, which the default mode handles poorly.

Abstract: Wireless base station device for handling wireless communication, e.g. DECT, between a plurality of associated wireless terminals and an IP network. The base station device has a radio transceiver, a network interface, and a processor with communication application and a communication session management software. The communication session management is arranged to control a communication session with an associated wireless terminal (upper layer management), while wireless communication with said associated wireless terminal involved with said communication session (lower layer) is handled by another base station device. Thus, the base station can manage separate operation of its upper and lower layer, thereby enabling e.g. hand-over of a session to and from other base stations. This allows self contained single casing base station devices to operate in a network without the need for at central server, and still such network is easy to extend by adding base stations.

Abstract: A method and application server for handling a supplementary services message in a communication network. A subscriber's Home Location Register (HLR) sends an Interrogation marker to the subscriber's Mobile-services Switching Center/Visitor Location Register (MSC/VLR) instructing the MSC/VLR to forward all supplementary services messages from the subscriber to the HLR. When the subscriber's user terminal sends a supplementary services message to the MSC/VLR requesting a supplementary service, the MSC/VLR forwards the message to the subscriber's HLR. The HLR retrieves an address of an IP Multimedia Application Server associated with the subscriber, and sends the supplementary services message to the addressed Application Server for handling the supplementary services request.
