Abstract: A method of compressing a current image of a sequence of images is disclosed. Firstly, the current image is transformed with a predetermined transform such as the DWT to provide a set of transform coefficients (step 2202). The method then retrieves (step 2303), for at least one transform coefficient of a current image, a predetermined number of bits, preferably two, of a corresponding transform coefficient of a previously compressed image of the sequence. The corresponding transform coefficient is truncated at a truncation bitplane and the retrieved bits are the least significant bits of the truncated corresponding transform coefficient. The transform coefficient of the current image is set to a new value that is a function of the retrieved bits (step 2306) and bits of the transform coefficients of the current image are stored for use in compressing one or more subsequent images of the sequence (step 2208).

Abstract: Generally described, multimode authentication over a VoIP communication channel is provided. A calling client and a called client may be authenticated for a communication channel establishment. When a calling client requests a call connection with a called client, the calling client is authenticated for the communication channel, based on exchanged contextual information between the calling client and the called client. Likewise, the called client is authenticated for the communication channel by the calling client. Upon authentication, a communication channel is established, over which the calling client and the called client are allowed to exchange more contextual and voice/multimedia information. During a conversation, when a secured service is desired by any of the clients, a series of authentication processes can be performed to grant access to the secured service over the communication channel without loss of the communication channel connection.

Abstract: An absorbent material comprises a flexible, skin-conformable, moisture-absorbent sheet member, optionally a net member in sheet form overlying and associated with the absorbent sheet member on at least one face thereof, and a hydrogel disposed on at least one of the net member, when present, and the absorbent sheet member in an amount of less than about 500 g of hydrogel per square metre per face, wherein the aqueous saline absorbency rate of the absorbent material through the face on which the hydrogel is disposed is less than about 300 seconds. Absorbent articles comprising the absorbent material and methods of manufacturing the material or articles are also described.

Abstract: A thermally-insulated reservoir 9 for a dispenser in which liquid is supplied from a bottle to a discharge outlet via a reservoir, has an inner wall 23 and an outer wall 24 defining a sealed and evacuated heat-insulating cavity 30 at least partially surrounding a liquid space 22. In one application of the invention the reservoir takes the form of a cooling vessel with the thermal means provided by a cooling coil 26. The invention may also be applied to reservoirs which form a hot tank with the thermal means provided by an electrical heating element.

Abstract: Cigarettes are manufactured having smokable rods with paper wrapping materials having additive materials applied thereto as patterns. The additive materials can be applied to a continuous, moving paper web on a cigarette making apparatus using application apparatus possessing four rollers. One roller has a series of pockets to receive additive formulation and to define the pattern of the formulation on the paper. The additive material can be applied to a transfer roller in roll interaction with a pick-up roller. Roll interaction of the transfer roller with an application roller causes transfer of the additive material from the transfer roller to the application roller. Additive material from the application roller can be transferred to the paper web that passes between the application roller and a back-up roller. A radiant dryer can be used to dry the additive material applied to the paper web.

A method of generating an electronic document including troubleshooting information and a set of troubleshooting commands for execution by a first computer system is also described.

Abstract: A process for producing olefins comprises providing a vapor product stream from an oxygenate to olefin reaction, the vapor product stream comprising C2 to C4 olefins, C2 to C6 carbonyl compounds and water. The vapor product stream is cooled to provide a first vapor effluent stream comprising no more than 10 wt. % water, and a liquid water-rich stream. The first vapor effluent stream, and a first wash flash vapor stream, are compressed from a first pressure to a second pressure greater than said first pressure to form a second vapor effluent stream, which is then cooled to form a cooled second effluent stream that is at least partially in the vapor state.

Abstract: The method performs a two-dimensional discrete wavelet transform on an image. The image comprises a plurality of blocks of pixels. The method generates (340) a current output block of subband data corresponding to a current block. The current output block is generated before either a one-dimensional discrete wavelet row or column transformation of a next block of pixels is completed, using intermediate lifting values stored (310, 350) during the generation of a plurality of previous blocks of subband data.
