When a displayed key element is touched by a probe, such as a finger, the screen area about the displayed key element and the finger, visually enlarges or “splats” confirming the selection of the particular key.

Abstract: A method and a system for framing variable-length packets in a data communications system are disclosed. The successive variable-length packets carrying users' data, are formed in a stream of chained packets comprising a header. Two CRC's are computed. One over the data and another one over the header however, including also the data CRC of the immediate previous packet, thus chaining successive packets in a steam of such packets. The invention also assumes that encryption is performed independently over header and corresponding CRC's and, on the other hand, over the data of current packet. The invention allows to better adapt the transportation of multi-media users' data in packets of variable-lengths while securing transport by chaining successive packets, thus preventing that accidental or malicious deletion and insertion of packets occur and remain undetected.

Abstract: A method and system for computing the shortest path for traveling inside a network and visiting a predefined list of network addresses. The method can be used by a system management workstation communicating and a mobile program visiting the list of networks addresses; the system management workstation communicates with said mobile program to get the list of network addresses to be visited; the system management workstation communicates also with all the networks addresses of the list to get the parameter values for determining the shortest path. The system management platform computes the shortest path by running a Kohonen neural network reading in input the references to nodes and their,parameter values which form bi dimensional coordinates; the output is the ordered list of network addresses to be visited by the mobile program.

Abstract: A data processing system with bootcode support for communicating with a noncompliant external device has a motherboard, non-volatile memory connected to the motherboard, a volatile memory, processing resources, a communications port that utilizes a first communications protocol, and one or more buses interconnecting those components. Startup instructions obtained from the non-volatile memory load a device driver for the external device from the non-volatile memory into the volatile memory. However, unlike the communications port, the external device utilizes a second communications protocol. Diagnostic instructions then utilize the device driver to communicate with the external device via the communications port.

Abstract: A system for providing prioritized queue management within a data transmission network node that supports different types of data frame traffic is disclosed herein. The system includes a frame buffer for storing an incoming frame that has an identifiable frame type. A queue is pre-associated with the frame type of the incoming frame such that upon arrival of the frame at the network node, the queue stores a location address at which the frame is stored within the frame buffer such that the frame is maintained within the queue. The queue that contains the frame is stored within a frame table. Processing means are provided for determining a time at which the queue forwards the frame from the frame buffer in accordance with a pre-determined sub-queue priority list. The system further includes time metering means associated with the frame for temporally assigning the frame to a virtual sub-queue among multiple virtual sub-queues that are associated with the queue.

Abstract: A method and system for enforcing a transmission control parameter for a virtual connection comprising multiple cells within an input port. The virtual connection has a nominal inter-cell arrival rate increment. Each of the cells are associated with a theoretical arrival time and an early arrival limit, wherein a difference of the early arrival limit from said theoretical arrival time delineates a lower boundary of a good zone, while the theoretical arrival time minus the sum of the early arrival limit and the nominal inter-cell arrival rate increment delineates an upper boundary of the good zone. The method includes determining an actual arrival time for an incoming cell from the cells that make up the virtual connection. Next, the actual arrival time is compared to the upper boundary and the lower boundary to determine whether or not the actual arrival time falls within the good zone.

Abstract: In a high-speed packet switched communication system such as an ATM network, the number of existing connections is limited by a Connection Admission Control (CAC) procedure. For each newly requested connection, the expected traffic rate is added to an already reserved bandwidth and a test is made whether the sum is above a given limit. According to the invention, the reserved bandwidth (r_bw) is updated not only for each new connection adding the additional requested capacity (RQ), but also in-between using an effective traffic capacity value derived from measuring the actual traffic (EC). For obtaining a reasonable effective traffic capacity value, the traffic sample sequence is modified by filtering out the “noise” representing short-time variations. This is done in an iterative procedure in which the cutoff between the signal and the “noise” portion is adaptively and dynamically changed so that the available buffer capacity can accommodate just that noise portion.
