A system of distributing video and/or audio information employs digital signal processing to achieve high rates of data compression. The compressed and encoded audio and/or video information is sent over standard telephone, cable or satellite broadcast channels to a receiver specified by a subscriber of the service, preferably in less than real time, for later playback and optional recording on standard audio and/or video tape.

Audio and video transmission and receiving system

The invention can enable monitoring of the display of content by a computer system. Moreover, the invention can enable monitoring of the displayed content to produce monitoring information from which conclusions may be deduced regarding the observation of the displayed content by an observer. The invention can also enable monitoring of the display at a content display site of content that is provided by a content provider site over a network to the content display site. Additionally, the invention can enable the expeditious provision of updated and/or tailored content over a network from a content provider site to a content display site so that the content provider's current and appropriately tailored content is always displayed at the content display site. Aspects of the invention related to transfer of content over a network are generally applicable to any type of network. However, it is contemplated that the invention can be particularly useful with a computer network, including private computer networks (e.g., America Online™) and public computer networks (e.g., the Internet). In particular, the invention can be advantageously used with computer networks or portions of computer networks over which video and/or audio content are transferred from one network site to another network site for observation, such as the World Wide Web portion of the Internet.

Content display monitor

A database search system that retrieves multimedia information in a flexible, user friendly system. The search system uses a multimedia database consisting of text, picture, audio and animated data. That database is searched through multiple graphical and textual entry paths. Those entry paths include an idea search, a title finder search, a topic tree search, a picture explorer search, a history timeline search, a world atlas search, a researcher's assistant search, and a feature articles search.

Multimedia search system

Library service protocols are provided for moving large data objects into an out of a data image library with attention to security, authentication, and consistency of related images stored in different machines. The protocol consists of particular message sequences, special tokens within messages, and out-of-sequence database changes.

Method and means for providing access to a library of digitized documents and images

A method and system for analysing and measuring multiple sources of data over a communications network (18) so as to ascertain information or usage of one or more resources, such as resource servers (2). A data collection and processing means (20) collects and processes the data sources which are forwarded to a reporting server (34) as a combined data source made available to interested parties.

Network resource monitoring and measurement system and method

In an image information search network system of the invention, image information file storing units of search stations installed at a plurality of different locations relatively distant from each other can commonly receive image information Each image information file storing unit stores image information for a predetermined number of pages and an AWS (advanced work station) serving as a search terminal stores and displays image information for a designated page File directory units for storing management information for searching image information are provided to some search stations, and are also used by the other search stations An image information processing unit can be connected not only to a terminal control unit but also directly to the AWS The terminal control unit is of a distributed processing type, and executes search processing for the respective AWSs The terminal control unit can execute image file transfer processing and printing processing independently of the search processing This allows independent control of the AWSs, a printer, and the image information file storing unit

The three-dimensional computation of steady and incompressible internal flows is of interest in numerical simulations of turbomachinery, and such simulations are currently under investigation, from inviscid to viscous flow analyses. First, surface pressure distributions have been measured for the stayvanes and the guidevanes of a Francis turbine. They are presented to verify the numerical results. Second, both inviscid and viscous three-dimensional flow analyses have been made, so as to predict the flow behavior in the same domain. Comparison of the measured pressure distributions to the predicted pressure distributions has been made to study the usefulness of the present simulations. It can be pointed out that a global analysis which includes a runner flow passage, except runner blades, is necessary to predict the three-dimensional flow characteristics and that inviscid flow analysis has the capability of good prediction for flow without separation. Viscous flow analysis gives similar results, though it is necessary to investigate further the improvement of prediction accuracy. Flow characteristics around the stayvanes and the guidevanes are also discussed.

PROBLEM TO BE SOLVED: To prevent the degradation of equipment efficiency and the generation of vibration and noises while suppressing the corrosion on the negative pressure face of an runner blade due to cavitation by suppressing the separation of a water stream from the negative pressure face of the runner blade. SOLUTION: This hydraulic machine runner 10 comprises a rotating shaft 11, a runner crown 12 connected to the rotating shaft 11, a runner band 13 located apart from the runner crown 12, and the plurality of runner blades 20 arranged around the rotating shaft 11 between the runner crown 12 and the runner band 13. Each runner blade 20 has a swollen portion 25 on the negative pressure face 23. The swollen portion 25 is provided near a front end P a of the runner blade 20 at the inlet side of a water stream during operating a water turbine. COPYRIGHT: (C)2007,JPO&INPIT
