  • Patent number: 6411027
    Abstract: The invention relates to a color display device comprising an in-line electron gun (5) for generating three electron beams (6,7,8), and a convergence unit (14′) to dynamically influence the convergence of the electron beams, preferably to decrease a distance (p) between the electron beams. The convergence unit (14′) comprises a ring-shaped element (21′) having four coils (22′). The coils (22′) comprise electrically conductive wires, which have been toroidally wound in a winding direction and according to a winding density distribution N (&phgr;) given by N (&phgr;)=N0 cos (2&phgr;). Here &phgr; is an angle enclosed by the X-direction and a line between an element of the coil and the center, which ranges between 0° and 360°, N0 is the winding density at &phgr; equal to 0°, and the sign of N &phgr; denotes the winding direction.

  • Patent number: 6411738
    Abstract: The variable bitrate coding method according to the invention comprises an iterative process including a first coding pass and a second prediction pass. The coding pass allows for a picture coding of a sequence with a constant quantization stepsize (and quality) and the prediction pass allows for a matching of the stepsize to the wanted target bitrate. After some iterations, a last step allows for a finer adjustment of said stepsize with respect to said target bitrate.

  • Publication number: 20020075172
    Abstract: A device is disclosed for encoding a stream of databits of a binary source signal (S) into a stream of databits of a binary channel signal (C), wherein the stream of databits of the source signal is divided into n-bit source words (x1, x2), which device comprises converting means (CM) conceived to convert said n-bit source words into corresponding m-bit channel words (y1, y2, y3) in accordance with a conversion of the Jacoby type, where m and n are integers, with m>n. The device further comprises control means (10) for carrying out DC-control on said binary channel signal by introducing a freedom of choice in the source-to-channel conversion.

  • Publication number: 20020073736
    Abstract: A method and device for the manufacture of a hollow cone (37) with a cone tip (31) whereby a parison of viscous material (35) is moulded into the shape of the hollow cone. An escape space (11) becomes accessible to the material in the vicinity of a cone tip to be formed. The moment the pressure present in the material in the vicinity of the cone tip to be formed exceeds a previously defined value. Breaking-off of the cone tip during or after moulding is prevented by this. The hollow cone is suitable inter alia for use in a cathode ray tube.

  • Patent number: 6406816
    Abstract: A multi-phase polymeric gel electrolyte for use in a rechargeable lithium battery has an ion-conductivity of more than 1 mS/cm and comprises a continuous ion-conductive liquid phase interpenetrating a solid phase. The solid phase which is obtained by polymerizing alkane monomers has a microscopic network structure which is selected such that when the electrolyte is employed in a rechargeable lithium metal battery, the battery is capable of being fully charged and discharged at a 0.2 C rate more than 20 times without short-circuiting due to dendritic growth. Suitable microscopic network structures are obtained using polydecandioldiacrylates. A method of preparing said electrolytes involves polymerizing a one-phase polymerizable composition which undergoes 1a phase separation during polymerization.

A transistor body region comprising a semiconductor layer (16) defining the channel area of the transistor and a gate insulator layer (18) is provided over the first electrode pattern (42). A transparent second electrode layer (46) is also provided. A negative resist (70) is exposed through the substrate (40), with regions of the negative resist layer (70) shadowed by the opaque layer (42b) of the first electrode pattern (42) remaining unexposed.

  • Patent number: 6405301
    Abstract: A data-processing arrangement for a plurality of parallel data processors is disclosed. An operation carried out by at least one of the parallel processors is defined by an instruction word or code. The data-processing arrangement includes a control processor that makes compositions of instruction words using instruction-word composing software. A composition (VLIW) of instruction words defines operations which are to be carried out in parallel. The compositions are then provided to each parallel data processor as required. Storage of instruction-word composing software generally requires less memory space than storage of independent VLIW-s for each parallel data processor. The cost-saving this provides generally outweighs any additional costs associated with providing the control processor. Thus, the data-processing arrangement yields better cost and memory efficiency.

  • Patent number: 6397250
    Abstract: A network communications system comprises a number of user stations (10,24), coupled via a data network (12) to a number of service provider host systems (14,16). The user stations (10) are registered as client stations at the host system (16) of a service provider, with the host system maintaining a database of registered client station identification data. The host system additionally maintains a directory of the client stations that are on-line at a given time, determined from periodic messages sent to the host by each client station. Callers (24,28) wishing to contact a client station (10) user first contact the service provider (16) which, from the directory, determines whether the user is currently on-line. If so, a paging message is generated by the service provider from data supplied by the caller and sent via the network (12) to the client station (10), the address of which is held in the service provider database.
