An information retrieval system in accordance with the principles of the present invention maintains a database that defines a relational association between a plurality of informational items in the system. The relational association is based on historical navigational behavior of users of the information retrieval system, and includes a relationship type, which is based on the characteristic similarities between the informational items, and relationship strength, which is based on the historical frequency of any related informational items being selected by a user within the same information retrieval session. When a navigation from one informational item to another information item is detected, the relationship type and the relationship strength of the two informational items are determined and stored in the database. During a subsequent selection of an informational item, any related informational items related to the selected informational item are sorted based on the respective relationship types and relationship strengths, and are provided in a sorted list from which the user can select.

Data is secured in a computer network to transparently establish and manage a separation of user-based communities of interest based upon crypto-graphically separated, need to know, security levels. Data from a source document, data object or data stream is filtered to form subsets of extracted data and remainder data based upon security levels for the communities. Extracts are stored in assigned memories. Full or partial plaintext reconstruction is permitted only in the presence of assigned security clearance for the community of the inquiring party. Encryption, corresponding to security levels, establishes separation of secured data. The information processing system uses a data filter to extract security sensitive words, data objects, etc., a distributed storage system and a compiler is used to reconstruct plaintext based on security clearance. Multiple level encryption in one document is also available.

The method for securing data includes establishing a group of security sensitive items, filtering data and extracting and separating the security items from remainder data. The filtered data are separately stored (locally on a PC or on another computer in a LAN or WAN or on the Internet.) A map may be generated. The filter and / or map may be destroyed or stored. The data input, extracted data and remainder data may be deleted from the originating computer. Encryption may be utilized to enhance security (including transfers of data, filter and map). Reconstruction of the data is permitted only in the presence of a predetermined security clearance. A plurality of security clearances may be used to enable a corresponding plurality of partial, reconstructed views of the plaintext (omitting higher security words). A computer readable medium containing programming instructions and an information processing system is encompassed.

Computer software for, computer apparatus for, and a method of automatically generating a user interface for a relational database comprising extracting schema information from the relational database and automatically generating corresponding schema and user interface metadata, storing the metadata in a repository, and automatically developing from the metadata a user interface appropriate to the relational database.

The steering angle of a vehicle is monitored using position sensors of an electric motor of an electric power assisted steering (EPAS) system. A position of the electric motor corresponding to the straight-ahead, center position of the steering system is stored in non-volatile memory during a steering calibration procedure, such as an end-of-line calibration in a vehicle assembly plant. Following power loss due to a dead battery, a steering angle zeroing procedure performed in a vehicle stability control (VSC) system generates a center position with enough accuracy to be within one electrical cycle of the motor. The pre-stored electric motor position is then used to determine the electrical cycle where the center position was located, and accurate monitoring of steering angle is resumed.

A method and system for the graphical specification and modification of reports is disclosed which enables data reports to be easily created via a report design dialogue. The report design dialogue includes a group-level outline panel containing controls for grouping, as well as other report controls such as those for sorting and aggregating. A method and system for creating a group-level outline panel using an existing database report is also disclosed. Finally, a computer-readable medium storing a computer-interpretable data structure that stores one or more report specifications is disclosed.

System and method for preventing vehicle accidents in which GPS ranging signals relating to a host vehicle's position on a roadway on a surface of the earth are received on a first communication link from a network of satellites and DGPS auxiliary range correction signals for correcting propagation delay errors in the GPS ranging signals are received on a second communication link from a station or satellite. The host vehicle's position on a roadway on a surface of the earth is determined from the GPS, DGPS, and accurate map database signals with centimeter accuracy and communicated to other vehicles. The host vehicle receives position information from other vehicles and determines whether any other vehicle from which position information is received represents a collision threat to the host vehicle based on the position of the other vehicle relative to the roadway and the host vehicle. If so, a warning or vehicle control signal response to control the host vehicle's motion is generated to prevent a collision with the other vehicle.

A reduced area imaging device is provided for use in medical or dental instruments such as an endoscope. In a first embodiment of the endoscope, connections between imaging device elements and between a video display is achieved by hard-wired connections. In a second embodiment of the endoscope, wireless transmission is used for communications between imaging device components, and / or for transferring video ready signals to a video display. In one configuration of the imaging device, the image sensor is placed remote from the remaining circuitry. In another configuration, all of the circuitry to include the image sensor is placed in a stacked fashion at the same location. The entire imaging device can be placed at the distal tip of an endoscope. Alternatively, the image sensor can be placed remote from the remaining circuitry according to the first configuration, and control box is used which communicates with the image sensor and is placed remotely from the endoscope. Further alternatively, the imaging device can be incorporated in the housing of a standard medical camera which is adapted for use with traditional rod lens endoscopes. In any of the configurations or arrangements, the image sensor may be placed alone on a first circuit board, or timing and control circuits may be included on the first circuit board containing the image sensor. The timing and control circuits and one or more video processing boards can be placed adjacent the image sensor in a tubular portion of the endoscope, in other areas within the endoscope, in the control box, or in combinations of these location.

A method and apparatus for displaying the evolution of an electronic document (e.g. word-processing document, portable-document-format file, spreadsheet, drawing, and the like), containing tracked changes, is disclosed. In accordance with the disclosed method and apparatus, the revisions of an electronic document may be treated as parent frames. In between the parent frames, child frames may be constructed from the combined images of their parent frames. To form a child frame, an image of a parent frame has a degree of translucency as it is combined with the translucent image of the other parent frame, such that every child frame contains traces of the images of both its parent frames. An input device (e.g. keyboard, mouse, touchpad, stylus, voice activation, and the like) may be used to control the frame visible to the user at any one time. The user may use the input device to traverse the frames at various speeds and in either direction, creating the visual illusion that a certain revision of the document is being morphed into its future revisions—or stripped off its changes as it is morphed into previous revisions—depending on the direction chosen by the user.

An intelligent framework is provided that is disposed between a high-level language environment and a database system environment. According to one embodiment, the framework programmatically receives information regarding definitions of data structures of objects participating in a software application and information regarding relationships among the objects. Based upon the particular request from the high-level language environment and upon the definitions and relationships, the framework programmatically and dynamically generates appropriate statements associated with the database system environment that accomplish the request. For example, the framework may issue statements to define the structure of a database, access information from the database, and / or manipulate information within the database.

A method and apparatus for allowing the user of an electronic device to enhance privacy over a display with the use of software, are disclosed. A security window including a translucent graphical effects region may be displayed on the electronic device such that it overlays content the user may choose to protect. The security window allows the protected content to remain discernable for the user of the device yet substantially indiscernible to a person at a further distance and / or greater viewing angle from the screen of the device. One or more security windows, each of which may be of any size, shape, texture, translucency level and any other graphical or behavioral properties may be displayed on the display associated with the electronic device. The user may control the size, shape, texture, translucency level and any other graphical or behavioral properties of the security window and graphical effects region. The user may invoke or terminate a security window with the single click of a button. Security windows may automatically attach to applications in focus, or be attached in response to a user command, and allow uninterrupted usability of those applications.
