  • Patent number: 6430703
    Abstract: In an object oriented software environment, a system and method is disclosed that addresses both state recovery and relationship recovery in the event of a system halt. The system is suited to enterprise-class distributed systems with extensive object relationships. Each essential object is saved in persistent storage. Essential values within each object are updated in storage according to a method within each object. After a partial or total halt of the system, the state of the software is reconstructed in a two phase process. In the first phase, the essential objects are restored from persistent storage, along with essential values. In the second phase, a method uniquely implemented by each object will reconstruct non-essential objects and variables. The second phase is ideally tailored to allow the system to be reconstructed even when the underlying hardware or software has been altered.

  • Patent number: 6427594
    Abstract: An infra-red dryer utilizes high velocity air jets which scrub and break up the moist air layer which clings to the surface of a freshly printed and/or coated sheet. The high velocity air jets are directed through multiple air flow apertures across an array of infra-red lamps onto the freshly printed and/or coated sheets. An extractor exhausts the moisture-laden air from an exposure zone while short wave infra-red radiation heats the ink and/or protective coating. The effective exposure to pressurized air is increased by the air jets which produce a balanced pressure air blanket along the sheet travel path. The moist air layer is displaced from the printed and/or coated sheet and is extracted from the press as the sheet moves through the exposure zone.

  • Patent number: 6429867
    Abstract: A system and method for generating and playing back three-dimensional (3D) movies are disclosed. The system is capable of partially rendering frames without relying upon exact viewpoint information. The partially rendered frames may be rendered to the extent possible without performing viewpoint-dependent processes, and then compressed and stored to a carrier medium. To reduce the amount of data to be stored, the viewer's possible viewpoints may be restricted (e.g., by defining a viewpoint-limiting volume or region). The resulting partially-rendered geometry data may be compressed using geometry compression. During playback, the compressed frames are read as a stream, and decompressed. Any final viewpoint-dependent rendering operations may then be performed (e.g., some lighting calculations and atmospheric effects, some fogging, specular highlighting, and reflections). A sensor such as a head-tracker may provide real-time viewpoint information that may be used by the playback system.

  • Patent number: 6428811
    Abstract: A thermally sensitive polymer-particle composite that absorbs electromagnetic radiation, and uses the absorbed energy to trigger the delivery of a chemical is disclosed. Metal nanoshells are nanoparticulate materials that are suitable for use in the present composites and can be made according to a process that includes optically tuning or tailoring their maximum optical absorption to any desired wavelength primarily by altering the ratio of the core diameter to the shell thickness. Preferred nanoshells are selected that strongly absorb light in the near-infrared and thus produce heat. These nanoshells are combined with a temperature-sensitive material to provide an implantable or injectable material for modulated drug delivery via external exposure to near-IR light. This invention provides a means to improve the quality of life for persons requiring multiple injections of a drug, such as diabetes mellitus patients.

  • Patent number: 6430639
    Abstract: A system and method for using a toggle command for setting and releasing a lock, i.e. a locktoggle. In an exemplary computer system, one or more processors are each coupled to a bus bridge through separate high speed connections, such as a pair of uni-directional address buses with respective source-synchronous clock lines and a bi-directional data bus with attendant source-synchronous clock lines. The locktoggle command is used to transmit both a lock request and an unlock request from a processor to a system coherency. point, e.g. the bus bridge. The system coherency point acknowledges when the lock has been established or released. While the lock is active, other processors are inhibited. from accessing at least the memory locations for which the lock was initiated. Locks are thus established at the system coherency point, which may advantageously allow for locking functionality in a non-shared bus system.

  • Patent number: 6430456
    Abstract: A method, system, and storage medium for increasing the efficiency of integrated circuit (IC) manufacture by improvements in manufacturing equipment usage are provided. Process tools are assigned to one of three operating states: up, down, or conditional. In the up state, process tools are available for manufacturing. After certain manufacturing steps, the quality of the ICs being made upon wafers is evaluated. If potentially defective ICs are found, process tools that have processed the wafer may be placed in the conditional state. In this state, process tools are allowed to continue manufacturing, albeit only for a limited period. The conditional state gives personnel time to determine which process tool is responsible for the defective product. The responsible process tool is then placed in the down state while all others are placed back in the up state. Once the problem with the process tool in the down state is presumably repaired, it is placed in the conditional state.

  • Patent number: 6427192
    Abstract: A microprocessor capable of caching victimized branch prediction information is disclosed. Branch prediction information is generated as branch instructions are executed over time. This prediction information is stored in a branch target buffer. The storage locations within the branch target buffer correspond to cache line locations within the microprocessor's instructions cache. Instead of discarding branch prediction information corresponding to instructions that are replaced or discarded from the instruction cache, the branch prediction information is stored in a victim branch prediction cache. Address information may also be stored to identify which instructions the prediction information corresponds to. The microprocessor's instruction cache is configured to receive and store instruction bytes, and the branch target array is coupled to the instruction cache and configured to store branch target information corresponding to the stored instruction bytes.

  • Patent number: 6425987
    Abstract: A new technique is provided using only one coating material (pure silicon) to deposit thin films in a high vacuum, and using an ion source with a working gas (or gases) to control the refractive index of the thin film. This new technique can deposit different kinds of optical thin films with different refractive indices or gradient-indices and make different kinds of multilayer interference filters without opening the vacuum chamber during the process. The way of evaporation or sputtering of the coating material or target uses “electron beam evaporation”, “DC or RF magnetron sputtering”, or “ion beam sputtering”, etc. The way of controlling the refractive index of the film involves mixing Ar with O2 and N2 or just the mixture of N2 or O2, and feeding the gases into the ion source, as shown in FIG. 1 and FIG. 2. The amount of gas and the way of feeding are controlled by computer software.
