  • Publication number: 20090071367
    Abstract: The present invention provides coating compositions for marking substrates, which comprises a colour former, an amine salt of an organic metal compound, a binder, a solvent, and optionally additional components, wherein the amine salt of the organic metal compound is of formula (I) in which X is silicon or boron, and E and F are the same or different and are selected from the group consisting of a, b, c, d, e, f, g, h in which R6 and R7 are the same or different are hydrogen, C1-4-alkyl, C1-4-alkoxy, halogen, amino or carboxy, and for X=silicon o=1 and p=0, and R1 is aryl, aralkyl or C1-4-alkyl, or o=1 and p=1, and R1 and R2 together form a one residue selected from the group consisting of a, b, c, d, e, f, g and h, and for X=boron o=0 and p=0, and R3, R4 and R5 are the same or different and are hydrogen, C1-12-alkyl, C1-6-hydroxyalkyl, allyl, aralkyl or arylsulfonyl, in which aralkyl or arylsulfonyl can be substituted with C1-4-alkyl, or R3 and R4 together with the nitrogen to which they are attached form a

  • Publication number: 20080207444
    Abstract: The present invention provides coating compositions for marking substrates, which comprise a colour former in an amount of from 0.01 to 50%, a metal salt of a carboxylic acid in an amount of from 0.01 to 50%, a binder in an amount of from 1 to 80% and an organic solvent in an amount of from 1 to 99%, wherein each amount is by weight based on the weight of the composition. The present invention also provides a process for the preparation of the composition of the present invention, substrates coated with these compositions and a process for preparing a marked substrate using these compositions.

  • Publication number: 20060267992
    Abstract: A system and method for applying non-homogeneous properties to multiple video processing units (VPUs) in a multiple VPU system are described. Respective VPUs in the system cooperate to produce a frame to be displayed. In various embodiments, data output by different VPUs in the system is combined, or merged, or composited to produce a frame to be displayed. In load balancing modes, each VPU in the system performs different tasks as part of rendering a same frame, and therefore typically executes different commands. In various embodiments, efficiency of the system is enhanced by forming a single command buffer for execution by all of the VPUs in the system even though each VPU may have a different set of commands to execute in the command buffer.

  • Publication number: 20060267989
    Abstract: Systems and methods are provided for processing data. The systems and methods include multiple processors that each couple to receive commands and data, where the commands and/or data correspond to frames of video that include multiple pixels. An interlink module is coupled to receive processed data corresponding to the frames from each of the processors. The interlink module divides a first frame into multiple frame portions by dividing pixels of the first frame using at least one balance point. The interlink module dynamically determines a position for the balance point that minimizes differences between the workload of the processors during processing of commands and/or data of one or more subsequent frames.

  • Patent number: 5005122
    Abstract: A network including a plurality of nodes which communicate over a communications link includes client nodes which are used by users and server nodes. At least one of the server nodes is a management server node, and other server nodes may comprise backup server nodes or software distribution server nodes. To initiate, for example, backup service, the management server node transmits a message to the backup server node to enable it to perform the backup. To initiate software distribution service, the management server node determines the nature of the service, such as downloading new versions, auditing use for licensing purposes, and the like, and transmits a message to the software distribution server node to initiate the operation. The network may include master and slave management server nodes, backup server nodes and software distribution server nodes to further divide the control of the respective operations.

  • Patent number: 4856436
    Abstract: A protective cover for electronic equipment automatically expanding by the spring action of a pair of telescoping arms (24) having a cover (48) of resilient material attached between. The arms (24) are positioned contiguous with a pair of bases (20) that are located parallel with each other on the floor on either side of the electronic equipment with a hinged cover enclosure (50) between the ends forming a "U" shape. The arms (24) are connected on the ends by a strut (26) holding the cover (48). Solenoids (58) retain the arms in a tensioned position and when electrically actuated release them. The spring action pivots the arms with its accompanying cover completely enveloping the equipment. A lever (64) arrangement overrides the solenoid action manually releasing the arms. The device is reset by manually rotating and compressing the arms while folding the cover (48) into the enclosure (50). The object is to protect expensive equipment from fire, smoke and water damage if a fire is in the vicinity.
