The present invention provides systems and methods of retrieving the pages according to the quality of the individual pages. The rank of a page for a keyword is a combination of intrinsic and extrinsic ranks. Intrinsic rank is the measure of the relevancy of a page to a given keyword as claimed by the author of the page while extrinsic rank is a measure of the relevancy of a page on a given keyword as indicated by other pages. The former is obtained from the analysis of the keyword matching in various parts of the page while the latter is obtained from the context-sensitive connectivity analysis of the links connecting the entire Web. The present invention also provides the methods to solve the self-consistent equation satisfied by the page weights iteratively in a very efficient way. The ranking mechanism for multi-word query is also described. Finally, the present invention provides a method to obtain the more relevant page weights by dividing the entire hypertext pages into distinct number of groups.

The present invention relates to an apparatus and method for the non-invasive analysis of physiological attributes, such as heart rate, blood pressure, cardiac output, respiratory response, body composition, and blood chemistry analytes including glucose, lactate, hemoglobin, and oxygen saturation. Using a combination of multi-functioning disparate sensors, such as optical and electrical, improvements are made over existing physiological measurement devices and techniques. The special configuration of one or more multi-functional sensors is used to non-invasively measure multi-wavelength optical plus one or more of ECG, Bio-impedance, and RF-impedance spectroscopic data. This information is used to develop self-consistent, non-linear algorithm in order to derive the physiological attributes while compensating for various forms of interfering effects including motion artifacts, sensor attachment variability, device component variability, subject physical and physiology variability, and various interfering physiological attributes.

The present invention provides a method for keeping a file system in a consistent state and for creating read-only copies of a file system. Changes to the file system are tightly controlled. The file system progresses from one self-consistent state to another self-consistent state. The set of self-consistent blocks on disk that is rooted by the root inode is referred to as a consistency point. To implement consistency points, new data is written to unallocated blocks on disk. A new consistency point occurs when the fsinfo block is updated by writing a new root inode for the inode file into it. Thus, as long as the root inode is not updated, the state of the file system represented on disk does not change. The present invention also creates snapshots that are read-only copies of the file system. A snapshot uses no disk space when it is initially created. It is designed so that many different snapshots can be created for the same file system. Unlike prior art file systems that create a clone by duplicating the entire inode file and all of the indirect blocks, the present invention duplicates only the inode that describes the inode file. A multi-bit free-block map file is used to prevent data from being overwritten on disk.

A system for distributing images creates a self-sufficient, self-consistent medical imaging and other medical information transfer file that contains image files and corresponding data sets that are bundled with an image viewer application. The medical image and data transfer file is prepared using object serialization and contains a deserialization application. The transfer file is created at an origination location and transmitted to a destination device as a packaged file over a computer network. The destination device receives the packaged file from the origination location and executes the viewer application with the image files and the data sets by opening the packaged file alone, without the need to run any other imaging / viewer application at the destination device. The viewer application has image viewing panes, an annotation tool, and image manipulation tools.

A data processing and method are provided for pre-decoding instructions. The data processing apparatus has pre-decoding circuitry for receiving instructions fetched from a memory and for performing a pre-decoding operation to generate corresponding pre-decoded instructions, which are then stored in the cache for access by the processing circuitry. If a pre-decoded instruction crosses a cache line boundary, then checking circuitry in respect of selected types of pre-decoded instruction checks for consistency between the first portion of the pre-decoded instruction stored within a first cache line and a contiguous second portion of the pre-decoded instruction stored within a second cache line.

If the consistency check is failed, or the pre-decoded instruction is not of a type for which consistency checking is supported, then re-generation of the pre-decoded instruction is triggered.

A headless computer entity having a plurality of disk drives operates to self restore to a known state, upon failure of either a system disk drive containing an operating system of the computer entity, or failure of a data disk drive containing application data. Depending upon whether the system disk and / or the data disk are replaced by a replacement disk, the computer entity configures itself with either deletion of application data on the data disk, or with deletion of application data on both the system disk and the data disk. The computer entity determines whether a new replacement disk has been installed by comparing a signature of the system disk with a signature of the data disk. If a replacement disk is detected, then the digital signatures are set by the computer entity such that the system disk and data disk have a self consistent set of hardware specific digital signatures. Application data is returned to a known good state after deletion.

The common concurrency runtime (CCR) provides a simple and self-consistent set of concurrency primitives that developers can use to more readily split their computation into more discrete chunks that can scale better with additional processors. This set of primitives provides for very scalable applications that are well suited for the coming world of ubiquitous communication and very large scale out for the number of local processors. The CCR may be implemented as a single library in C# that implements channels with input and asynchronous output capabilities, along with an atomic test-and-input primitive. On top of this, richer derived operators (e.g., choice, join, replication, reader-writers, scatter-gather, etc.) may be encoded. Thus, existing C# may be built upon to provide the capability to concurrently issue I / O requests to remote systems while simultaneously performing other functions locally to increase the efficiency of the distributed system. Because it is based on C#, the CCR allows users to take advantage of a well-known programming model to address unique issues in a new programming environment.
