  • Patent number: 6578069
    Abstract: Techniques are presented for allowing clients and servers in a computer network executing the WebDAV protocol to identify a specific version of a specific resource a specific version using a resource tag. The resource can be identified even though it has been changed at a server or at an off line local cache of a client that is disconnected from the network and then later re connected to the network for uploading. Also, a resource UID is presented that will not change despite changes to the URL or the resource tag of the resource. Each resource UID of each resource can be cached locally at a client and can be stored at network server in an index. The index allows the resource to be identified uniquely across a collection in a database at a server, across a database at the server, across the entire server, or across all servers in the network.

  • Patent number: 6577346
    Abstract: A method and system are described for identifying video segments (e.g., commercials or television programs) without using any identification data that may or may not be provided in the non-displayed overscan portion or the vertical blanking interval of the video signal. Instead, the video segment is identified by recognizing patterns in the viewable portion of the video image data and/or in the video sound data. If the pattern is unique to a specific video segment, that video segment is identified by, for example, looking up the pattern in a table correlating patterns with video segment identifications. Any number of functions may be performed using this identification.

  • Patent number: 6573340
    Abstract: Biodegradable polymer blends suitable for laminate coatings, wraps and other packaging materials manufactured from at least one “hard” biopolymer and at least one “soft” biopolymer. “Hard” biopolymers tend to be more brittle and rigid and typically have a glass transition temperature greater than about 10° C. “Soft” biopolymers tend to be more flexible and pliable and typically have a glass transition temperature less than about 0° C. While hard and soft polymers each possess certain intrinsic benefits, certain blends of hard and soft polymers have been discovered which possess synergistic properties superior to those of either hard or soft polymers by themselves. Biodegradable polymers include polyesters, polyesteramides and thermoplastically processable starch. The polymer blends may optionally include an inorganic filler. Films and sheets made from the polymer blends may be textured so as to increase the bulk hand feel.

  • Patent number: 6574218
    Abstract: A system and method for providing multimedia data streaming over a mixed network including a packet-switched and circuit-switched network. The multimedia source server performs both source coding to reduce the overall size of the data and channel coding to provide redundancy for packet reconstruction of lost or late packets. The source coding (or compression) and channel coding (protection against packet loss) are designed jointly, but are performed at two different locations to achieve optimum utilization of bandwidth. The channel coding is removed and packet reconstruction or concealment is performed at the edge of the packet-based network prior to passing the multimedia data on to the circuit-switched network. Retransmission is unnecessary in the present invention which is undesirable for real-time data streaming. A bidirectional embodiment is also described.

  • Patent number: 6573913
    Abstract: Systems and methods for repositioning and displaying objects in multiple monitor environments are disclosed. When two or more of the monitors have different color characteristics, images moved between monitors are processed to take advantage of the particular color characteristics of the monitors, while reducing the processing resources that might otherwise be needed to entirely render the image from scratch. For instance, an image positioned within a first monitor space can be repositioned such that a first portion is displayed in the first monitor space and a second portion in the second monitor space. The data representing the first portion of the image is moved from a first location to a second location in a frame buffer in a bit block transfer operation. If the first and second monitors have the same color characteristics, the data representing a second portion is also transferred using a bit block operation.

  • Patent number: 6573571
    Abstract: The present invention relates to a semiconductor structure including metal nitride and metal silicide, where a metal silicide layer is formed upon an active area that is part of a junction in order to facilitate further miniaturization that is demanded and dictated by the need for smaller devices. A single PECVD process makes three distinct depositions. First, a metal silicide forms by the reaction: MHal+Si+H2MSix+HHal, where M represents a metal and Hal represents a preferred halogen or the like. Second, a metal nitride forms upon areas not containing Si by the reaction: MHal+N2+H2MN+HHal. Third, a metal nitride forms upon areas of evolving metal silicide due to a diffusion barrier effect that makes formation of the metal silicide self limiting. Ultimately, a metal nitride layer will be uniformly disposed in a substantially uniform composition covering all underlying structures upon a semiconductor substrate.

  • Patent number: 6573729
    Abstract: The present invention synthesizes a prescribed impedance. The impedance is synthesized by generating a current having a value substantially equal to a voltage divided by a prescribed impedance. Sensing the line voltage and converting that sensed line voltage to its digital equivalent accomplish this first step. The digital line voltage is processed by a factor related to the prescribed impedance to produce an output voltage that has a value substantially equal to the sensed voltage divided by the prescribed impedance. The output voltage controls a voltage to current converter that generates the appropriate current across the points or terminals where the line voltage was measured. Thus, the prescribed impedance is generated across these points or terminals because the line voltage divided by the generated current is substantially equal to the prescribed impedance.

  • Patent number: 6571392
    Abstract: In interactive television, information from an information resource may be displayed along with television video in a synchronized fashion. When information is to be displayed at a point in the television video, a Uniform Resource Identifier (URI) that identifies the information resource is broadcast along with the television video on a one-way broadcast communication channel. A receiver unit receives the URI from the broadcast channel. If the information resource identified by the URI is available locally (for example, is present in local storage on the receiver unit), then the receiver unit uses the URI to retrieve the information resource locally. If, on the other hand, the information resource is not available locally, then the receiver unit uses the URI to retrieve the information resource from the Internet.

  • Patent number: 6570439
    Abstract: In order to achieve reliable operation despite the greater interference susceptibility of a circuit (1) at a reduced power supply, in addition to a global power supply path (6, 7) to supply the circuit (1) in operating state, a rest state power supply path (10, 11) is provided with which the circuit (1) is connected in particular via transistor diodes (14, 15). As soon as the circuit (1) by way of first switches (12, 13) is separated from the global power supply path (6, 7), because of the voltage loss in the transistor diodes (14, 15) it is supplied by the rest state power supply path (10, 11) which is provided exclusively to supply circuit parts (1) set into rest state and on which therefore fewer current or voltage peaks can occur.
