Deployment of the scroll bar may be by an animated process resembling an unrolling. By deploying the scroll bar only as required and requested by a user, the scroll bar may be enlarged for use and additional functions supported.

Abstract: This invention relates to personal computer systems and, more particularly, to such a system having security features enabling control over access to data retained in such a system. The present invention protects a trusted personal computer system against a probing attack, in which an unauthorized user would attempt to overcome the security feature elements of the personal computer system by inserting some form of probe into an opening provided in the system enclosure for other, legitimate, purposes such as cooling air flow or removable media insertion. A plurality of security feature elements are mounted within the enclosure for selective activation to secure and non-secure states and are disposed at locations inaccessible to any unauthorized user of the personal computer system attempting to affect the operation of any one of the security feature elements by insertion of a probe through an opening.

Abstract: This invention deals with a method and system for dynamically adjusting the communication bandwidth assigned to an audio channel connection in a high speed digital network. More particularly, the invention is made to track the activity of a voice assigned connection (e.g. a PBX or PABX entry to the network), define a so-called activity bit for each block of audio channel signal and then dynamically adjust the assigned network communication bandwidth accordingly. Adjustment of the communication bandwidth is accomplished by integrating the audio channel activity bits through a predefined integration function, the result of which is then compared against predefined threshold values in order to determine an appropriate bandwidth setting for the audio channel.

Abstract: An effective mechanism for cache flushing that can be applied to a memory system operated in dual-mode is disclosed. The dual-mode is composed of two modes using two physically distinguished main memory spaces respectively at a common logical address in at least a portion of the whole address area. The interruption of the signal (SMIACT#) that represents the switching of the mode by secondary cache is provided. When SMIACT# is generated by CPU and it is detected by the system core, the system core switches the memory bank for the cache memory to write back, resulting in violating memory consistency between the cache and main memory. This invention keeps the SMIACT# from reaching the system core before the cache flushing is over, assuring the content of the cache memory to be written back to a correct memory bank where the data originally resided, since the system core believes that the mode has not yet been switched though the CPU actually generated SMIACT#.

Abstract: The present invention contemplates a display generating system, preferably a computer such as a mobile client system, in which text entry to supply data for a defined field in a form or the like is facilitated. In particular, the present invention contemplates combining certain functions heretofore separated in a display which accepts data entry such as letters or numbers entered by hand using a stylus or the like. In a system implementing this invention, the functions of providing a cursor which indicates the location for data entry and providing a field displaying or receiving data entry are combined. By this combination, the field receiving or displaying an entry is positioned immediately adjacent the displayed field for such entry, permitting a user to focus attention on a single location in the display as distinguished from dividing attention between a location at which a cursor prompts for data to appear and a separated field at which the entry is entered or displayed.

Abstract: A display device comprises a cathode and a permanent magnet. A two dimensional array of rows and columns of channels extends between opposite poles of the magnet for receiving electrons from the cathode. A screen has a plurality of phosphor pixels each corresponding to a different channel and each comprising a plurality of sub-pixels facing the side of the magnet remote from the cathode. Grid electrode means is disposed between the cathode means and the magnet. A plurality of pairs of anodes are disposed between the magnet and the screen and extending parallel to the columns of channels. Each pair corresponds to a different column of channels and each pair has first and second anodes extending along opposite sides of the corresponding column of channels. Address means supplies control signals to the grid electrode means to selectively control flow of electrons from the cathode through each channel to the corresponding pixel.

Abstract: A computer system, and particularly a handheld mobile client system, in which a user input device such as a keyboard or a scanner, coupled by a tethering conductor or a wireless link such as an infrared radiation link, functions as a master while the central processing unit of the system functions as a slave in receiving input digital signals.

Abstract: A computer system has a central processing unit ("CPU") and a plurality of peripheral devices. A bus interconnects the CPU and the peripheral devices. Command signals are transmitted over the bus including an initiator ready signal ("IRDY"), a device select signal ("DEVSEL"), and a target ready signal ("TRDY"). First and second direct memory access devices ("DMA") are connected to the bus and assigned the same address space. First and second switches selectively connect and disconnect the DEVSEL and TRDY signals that are output from the first and second DMA devices, respectively. Controller logic receives the DEVSEL and TRDY signals and directs the opening and closing of the first and second switches.

Abstract: OCR processing involves: acquisition of images from image capturing devices; determination of location/size/style for each character; normalization; smoothing for large corners; smoothing by the deletion of individual protruding and extraneous dots; extraction of features; pattern matching; automatic error correction using a word dictionary; and output of recognition results.In the present invention, high speed software processes accomplish smoothing large corners and deletion of individual protruding and extraneous dots. In this software processing, the smoothing process is performed by shifting bit rows and using only the logical operators NOT, AND, and OR; not used are the often employed conventional conditional branch commands, such as the "if then else" and "switch" statements. This smoothing method (using only NOT, AND, and OR) contributes to a substantial reduction in the processing speed.
