Patent number: 6377941Abstract: A method of achieving automatic learning of an input vector presented to an artificial neural network (ANN) formed by a plurality of neurons, using the K nearest neighbor (KNN) mode. Upon providing an input vector to be learned to the ANN, a Write component operation is performed to store the input vector components in the first available free neuron of the ANN. Then, a Write category operation is performed by assigning a category defined by the user to the input vector. Next, a test is performed to determine whether this category matches the categories of the nearest prototypes, i.e. which are located at the minimum distance. If it matches, this first free neuron is not engaged. Otherwise, it is engaged by assigning the matching category to it. As a result, the input vector becomes the new prototype with the matching category associated thereto. Further described is a circuit which automatically retains the first free neuron of the ANN for learning.Type: GrantFiled: June 22, 1999Date of Patent: April 23, 2002Assignee: International Business Machines CorporationInventors: Andre Steimle, Pascal Tannhof

Patent number: 6377996Abstract: The present invention switches a source of a streaming session between a primary server and its client, from the primary server to another server at arbitrary points during the progress of the streaming session. The switching of the source is accomplished through the use of a virtual socket capable of simultaneously phasing in a new streaming connection while phasing out an old streaming connection during a streaming session that preserves the temporal progress of the session. The virtual socket acts as a client-based intermediary between the client and one or more streaming servers, thus enabling a client application to establish a streaming connection with respect to content and not to the end-party, i.e., server.Type: GrantFiled: February 18, 1999Date of Patent: April 23, 2002Assignee: International Business Machines CorporationInventors: Leon L.

Patent number: 6377257Abstract: A system and method for seamlessly combining client-only rendering techniques with server-only rendering techniques. The approach uses a composite stream containing three distinct streams. Two of the streams are synchronized and transmit camera definition, video of server-rendered objects, and a time dependent depth map for the server-rendered object. The third stream is available to send geometry from the server to the client, for local rendering if appropriate. The invention can satisfy a number of viewing applications. For example, initially the most relevant geometry can stream to the client for high quality local rendering while the server delivers renderings of less relevant geometry at lower resolutions. After the most relevant geometry has been delivered to the client, the less important geometry can be optionally streamed to the client to increase the fidelity of the entire scene.Type: GrantFiled: October 4, 1999Date of Patent: April 23, 2002Assignee: International Business Machines CorporationInventors: Paul Borrel, Shawn Hall, William P.

Patent number: 6377098Abstract: A latch device having a selectable feedback path includes a retaining device and system isolation device. The retaining device retains within the feedback path a logical value to be written out. The logical value is latched during an active clock signal. The system isolation device disconnects the retaining device from the feedback path during a write operation. Then, when the logical value is written out, the system isolation device reconnects the retaining device. Thus, the feedback path of the latch device may be disconnected to allow for a change in the latch state without overdriving a feedback inverter.Type: GrantFiled: April 21, 2000Date of Patent: April 23, 2002Assignee: International Business Machines CorporationInventor: Chris J. Rebeor
