Appl. No.:

09/881507

Inventors:

Jing Liu - Pacifica CA

International Classification:

G06F 1730

US Classification:

707102, 707 10

Abstract:

Techniques used in a distributed database system for simplifying copying of objects from one database system in the distributed database system to another and establishing the infrastructure necessary for the distributed system in the database systems. One application of the techniques is setting up a cache database system that has a subset of the objects in another database system and establishing a link for redirecting misses between the cache and the other database system. Also included is the infrastructure in the cache and the other database system for an authentication proxy that establishes sessions in the other database system for users to perform operations that have been redirected as a result of a miss in the cache. The techniques require only that the user supply simple descriptions of some of the objects to be copied; the techniques locate the necessary dependent objects and make objects for the infrastructure. Some of these are descriptions of the infrastructure objects that are copied to the cache and executed there and others are objects that are added directly to the other database system.

US Classification:

707103R, 707100, 707101, 707102, 7071041

Abstract:

A method and system are provided for instantiating objects for participation in information sharing relationships. According to one technique, a copy of an object is made, where the copy includes all changes made prior to a particular point in time, and no changes made after the particular point in time. The copy is used to create a second object. Data that reflects the particular point in time is stored, and subsequently used to determine which changes should be applied to the second object. Data that indicates that the creation time of the second object is stored, and subsequently used to determine which changes should be applied to the original object.

US Classification:

370235, 370253, 709224

Abstract:

A network monitoring device includes a flow processing element, disposed to receive flow information relating to network flows, and to generate a set of virtual packets, each representing a portion of a network flow. The virtual packets are maintained in a time-sequential order, and read by elements of the network monitoring device to generate information relating to network traffic, such as symptoms affecting the communication network, problems affecting the communication network, and otherwise. The network monitoring device randomly samples virtual packets, with at least one of two effects: (1) flow information from traffic reporting devices that are themselves sampling at differing rates can be equalized, with the effect of standardizing information from all of them; (2) the network monitoring device itself can restrict its attention to a fraction of all virtual packets, with the effect of keeping up with a relatively large number of virtual packets.

US Classification:

709224, 709223, 709225, 709226

Abstract:

A network monitoring system maintains both information regarding historical activity of a network, and information regarding emergent activity of the network. Comparison of historical activity of the network with emergent activity of the network allows the system to determine whether network activity is changing over time. The network monitoring system maintains data structures representing a p. d. f. for observable values of network parameters. Recent activity of the network can be compared with both the p. d. f. for historical activity and for emergent activity to aid in determining whether that recent activity is within the realm of normal, and whether network activity is changing over time. The network monitoring system adjusts that information regarding historical activity of a network in response to emergent activity of that network. The network monitoring device determines information regarding time-dependent activity of that network in response to spectral analysis regarding historical activity of that network.

H01L 25/075

Abstract:

Embodiments of the invention include a plurality of light emitting devices (), one of the light emitting devices in the plurality being configured to emit light having a first peak wavelength. A wavelength converting layer () is disposed in a path of light emitted by the plurality of light emitting devices. The wavelength converting layer () absorbs light emitted by the light emitting device and emits light having a second peak wavelength. The light emitting devices () are mechanically connected to each other only through the wavelength converting layer (). In other embodiments a light converting layer is placed over the light emitting devices and an adhesive or optical element layer is placed at the side surfaces and over the light converting layer, the light emitting devices are mechanically connected to each other only through the wavelength converting layer.

Abstract:

Our inventive method enables stereoscopic 3D displays to be watched by 3D and 2D viewers simultaneously. Ghosted images observed on traditional 3D displays can be eliminated for viewers without stereoscopic glasses while 3D perception is preserved for viewers with glasses. A preferred method for displaying an image on a 3D+2D television comprises displaying a composite image (“L+wN”), comprising a left (“L”) image and a weighted image (“wN”), for a first period of time; and displaying a right (“R”) image for a second period of time. The display of “wN” partially cancels out the perception of “R” to mitigate ghosting for viewers not wearing 3D eyeglasses. In the illustrative embodiment, “wN” is a weighted negative version of “R”.
