Abstract: An interactive multimedia book provides hands-on multimedia instruction to the user in response to voiced commands. The book is implemented on a computer system and includes both text and audio/video clips. The interactive multimedia book is accessed by voiced commands and natural language queries as the primary user input. The displayed text is written in a markup language and contains hyperlinks which link the current topic with other related topics. The user may command the book to read the text and, as the text is read by the voice synthesizer, a word which is also a hyperlink will change its attributes upon being spoken. The user will be able to observe or hear this and simply utter the word which is the hyperlink to navigate to the linked topic.

Abstract: A controllable mechanism for by-passing Layer 4 (L4) classification is based on the insertion into a set of Layer 3 (L3) rules in an L3 lookup tree set of Layer 4 (L4) Classification Required Flags. The state of the L4 classification flag is set by comparing the L4 classification rule to an IP (Internet Protocol) lookup rule. Routing is accomplished by selecting which rule to apply to the data packet and reading the state of the corresponding L4 Classification Required Flag. In response to a first state of the corresponding L4 Classification Required Flag, an L4 classification is performed followed by a routing of the data packet. In response to a second state of the corresponding L4 Classification Required Flag performing a routing of said data packet. In a second embodiment, the method inserts into a set of L3 rules in L3 lookup means a set L4 Classification Required Flags and Global Flags.

Abstract: A large liquid crystal display optical structure can be created by providing a transparent substrate with a dark mesh pattern disposed thereon. A means for optical scattering is over, adjacent, or surrounding the dark mesh, with a polarizer laminated to a smooth surface of the means for optical scattering.

Abstract: The screen display scale is changed in an easy and intuitive manner, without intermediate steps or operations, and without taking up additional screen display area. At least one so-called scroll bar must be displayed on the screen and be functional at any time that the scale could be changed by the user. Additional function is loaded onto screen scroll bars to support the change of scale function as well as the scrolling function. The scroll bar is composed of a bar and a slider, and the slider position and size respectively indicate the location of working area relative to the virtual screen and the relative size of the working area as a function of the total size of the virtual screen area. Scrolling, or panning, is accomplished by moving the slider within the bar. In addition, the size of the slider can be changed in order to effect a change in the scale of the working area, thereby providing a zoom function for the scroll bar.

Abstract: A vector operation capability is integrated into the execution unit (E-Unit) portion of a computing systems central processing unit (CPU) designed to support scalar instruction processing. The fixed point and floating point instruction functional units in the E-Unit that are required to implement the vector instruction set are pipelined. A set of vector registers are added to the architected data registers contained in the E-Unit. The E-Unit control logic is modified to queue and schedule both vector and scalar instructions, The E-Unit's load and store unit bandwidth capability to support the transfer of the contiguous blocks of data normally associated with vector processing are enhanced. The integrated vector and scalar capability allows for improved processing of programs that include both vector and scalar type instructions.

Abstract: Higher functions terminals and lower function terminals, as well as dual mode terminals that are selectively operated at either functional level, are simultaneously supported on a common control unit interface in an information handling system. Communications with single mode terminals are directed to a buffer portion having a predetermined base address. Each dual mode terminal contains a buffer that is partitioned into respective portions used for communications at different function levels. Communications at a lower functional level are conducted through the buffer portion containing the base address while communications at a higher functional level are redirected to a buffer portion containing shifted addresses. The control unit includes means for determining the suitable level of terminal function and adjusting the addressing of the terminal buffer accordingly.

Abstract: A system for the transmission of information between elements of a data processing complex and a method for establishing such a system. Two elements of a data processing system are connected by a physical link comprising multiple conductors attached to transceivers at channels in each data processing element. Once the transceivers have been synchronized, commands and responses are exchanged which ensure that all of the transceivers in a channel are connected to the same channel on the other end of the conductor. If the transceivers are considered configured and an entry is made in a Configured-Transceiver table. A search is made of an Allowed-Operational-Link table which contains sets of transceivers which are allowed to become operational links. The set of transceivers thus found, is compared against the Configured-Transceiver-Table to verify that all of the members of the set have been configured. If a match is found, this set of transceivers becomes an Intended-Operational-Link.

Abstract: A cryptographic facility implements a multiple key part import procedure. The installation manager can verify that a key part has been correctly entered and has not been compromised. The security requirement for the procedure is that no single party can subvert the system security by misusing the procedure. This is accomplished by the use of a control-vector-dependent verification pattern to indicate that each key part has been accepted by using the proper control vector and the use of different key switch positions to specify whether the key part is a master key part or an operational key part and whether the key part is a first part or a subsequent key part. The apparatus provides an automatic reset of the key part register at the completion of each key-entry instruction so that each key part can be imported only once. This prevents the same key part from being imported twice as different key part types. The apparatus also prevents a key part from being combined with itself to create a known key.

Abstract: A conventional single node operating system is provided with a distributed file management system (DFS) with a plurality of nodes and a plurality of files. The DFS uses the UNIX operating system tree structure employing inodes (data structure containing administrative information for each file) to manage the local files and surrogate inodes (s.sub.-- inode) to manage access to files existing on another node. In addition, the DFS uses a lock table to manage the lock status of files. The method which implements the DFS locking of records and files involves the following steps. If the file is a local file, then the UNIX operating system standard file locking is used. However, if a remote file is to be locked, the UNIX operating system LOCKF and FCNTL system calls are intercepted and an remote process call (RPC) DFS.sub.-- LOCK.sub.-- CONTROL is executed. The server node receives the remote process call and carries out the lock request.

Abstract: A method for interfacing between a product planning conceptual design tool and a CAD/CAM environment allows an indented bill of materials to be imported to the CAD/CAM environment while retaining the characteristics as a primitive text file. The conceptual design tool uses a sketch sheet approach on a computer display to enter the functional design of a new or modified product, thereby encouraging the designer to use a top down approach to the design process. The user keys in item information, and the system automatically draws a hierarchical tree structure on the computer display. The system then automatically generates an indented bill of materials which is stored in a graphics standard file that retains the character of text primitives. From this file an image of the bill of materials can be displayed in the CAD/CAM environment. The designer can use this image as an aid in the design process. Item names and numbers can be copied from the displayed bill of materials to the CAD/CAM image.

Abstract: Information from multiple CICS host applications is gathered and the information is displayed on a single display screen. The information includes graphics, reports, and monitoring information. The display screens that the user is presented with are in a format that correspond to the host display screens that are commonly employed in large data processing (DO) centers. A host based status array is used to minimize the overhead of the communications between the host and the PC. The IBM 3270-PC or other microprocessor with a host communications interface receives existing, summarized information and reduces the information to a complete, accurate picture of the multiple applications that enables the operator to have timely information and respond effectively in a complex DP environment. The alarm information is organized to effectively call the operator's attention to a key problem quickly and efficiently.

Abstract: Methods and apparatus are provided for driving a vehicle from a remote control station achieving tele-operation of the vehicle. A television sensor mounted on the vehicle provides video image information which is reduced in bandwidth by a factor of approximately 1000:1 for transmission by narrow band RF data link to a remote control station. The large bandwidth reduction is accomplished by first sampling the video output of the sensor at a reduced frame rate and then compressing the data further by standard data compression techniques. Vehicle position and attitude data which may be derived from the vehicle's on board inertial reference unit are also transmitted via narrow band data link to the control station.

Abstract: A display technique allows the user to input information to a computer in the form of color with character text. The technique provides an ergonomic approach to convey information to an application program by using color to specify functions or attributes. Colors are used to reduce the number of interactions necessary to accomplish a task between the user and the application program. In many systems a command has to be typed to save a file. These commands range in size from one to many characters and require the user to key in each character and the filename. The improvement described is a technique for typing the filename in a specified color that the application interprets to mean, for example, Save the file. The technique assigns a color to data elements input to the system. The color is interpreted by the application to indicate what specific function, attribute or value should be associated with the data element.

Abstract: A method for controlling the use of a cryptographic key at a using station by a generating station in a network of generating and using stations is disclosed. A control value specifying the use of the cryptographic key is transmitted with a generated cryptographic key to at least two designated using stations one of which may be the generating station. Each of the generating and using stations have cryptographic facilities that securely store a master key. Two techniques are described for controlling the use of the cryptographic key. In the first, the key and the control value are authenticated via a special authentication code before use by the using station. In the second, the key and control value are coupled during key generation such that the key is recovered only if a correct control value is specified. In addition, two techniques are described for controlling who may use the cryptographic key.

The adapter (200) includes an electrical connector (218) which is copmlimentary to the electrical connector (30). In a third configuration, a pair of lantern batteries (350 and 352) are fitted in the battery compartment (13) to contact a contact pattern (300) positioned on the back wall (20).

Abstract: A bill of material for a product is automatically created from a query session on the product structure. The user is first queried on functional product structure. A top down approach, rather than a focus on design details, is encouraged. As the query occurs, a hierarchical tree structure is created on the screen for the user to view. Within a relational database, the structure data is kept in a table which is accessed by item number. Once the product structure is established, the user can see the hierarchical tree and check it for correctness. From the tree structure, which has been captured in the relational database, the indented bill of material is built.

Abstract: A system for the interactive control of a display such as a CRT (cathode ray tube) or the like, produces a visual representation of at least one variable in the form of a trend or bar graph. The system includes a personal computer having a cursor control and a display. The system operator can select a variable for display, and then select a location within which the visual representation of the variable is to appear and a range of the variable which is to be displayed within the selected region. The system responds to the operator's selections for producing a visual representation in the form of a trend or bar graph of the selected variable within the selected range at the operator-selected location.
