International Classification:

H03K 19177

US Classification:

326 41, 326 40, 326 39, 326 38

Abstract:

An improved, scalable CPLD device has a two-tiered hierarchical switch construct comprised of a Global Switch Matrix (GSM) and an even number of Segment Switch Matrices (SSMs). An even number of Super Logic Blocks (SLBs) are coupled to each SSM. Each SSM and its SLBs define a segment that couples to the GSM. Each SLB has a relatively large number of inputs (at least 80) and can generate product term signals (PTs) that are products of independent input terms provided from the SSM to the SLB inputs. Some of the product terms generated within each SLB are dedicated to SLB-local controls. Each SLB has at least 32 macrocells and at least 16 I/O pads which feedback to both to the local SSM and the global GSM. 100% intra-segment connectivity is assured within each segment so that each segment can function as an independent, mini-CPLD. Each SSM has additional lines, dedicated for inter-segment (global) communications.

International Classification:

H04L 1256

US Classification:

370389

Abstract:

An apparatus and method for bundling frame relay packets under one or more common DLCIs. A plurality of frame relay packets is received in a frame relay access device. A common bundling DLCI is associated with each of the frame relay packets based on a configuration parameter that can be modified by a human operator to have at least a first state or a second state. When in the first state, the configuration parameter indicates that the common bundling DLCI is included in voice frames generated in the frame relay access device. In the second state, the configuration parameter indicates that the common bundling DLCI is not included in voice frames generated in the frame relay access device. Each of the frame relay packets has an initial DLCI which is used to determine a multiplexing value. Each of the frame relay packets is transmitted over a frame relay network using the common bundling DLCI and its respective multiplexing value.

International Classification:

H04L 1256

US Classification:

370465

Abstract:

An apparatus and method for communicating link status information for permanent virtual circuits that share a data link connection identifier. A first frame relay packet that includes link status information for a plurality of virtual circuits that each share a first data link connection identifier is received via a frame relay network. Using the link status information in the first frame relay packet, a second frame relay packet that conforms to a standard local management interface status message format is generated. The second frame relay packet is transmitted to customer premise equipment.

Appl. No.:

9/282047

Inventors:

Michael Aratow - Mountain View CA
Robert S. Simon - San Francisco CA

Assignee:

Noegenesis, Inc. - Moutain View CA

International Classification:

G06F 1900

US Classification:

701120

Abstract:

A computer system for displaying terrain, weather and aviation information includes a terrain database, an aviation map database, a weather database, an air traffic database, an airplane specific database and a route database. A processor is coupled to the terrain database, the aviation map database, the weather database, the air traffic database, the airplane specific database and the route database and configured to determine a position and heading of an airplane over the terrain based on the route database, to compute terrain information, aviation map information, air traffic information and weather information relative to the airplane and to compute and display flight parameters associated with the airplane using the airplane specific database. Advantages of the invention include the ability to supply a pilot with information that he can use to visualize his flight and approach to the destination airport. This provides improved information to the pilot so that he can make his decision whether to make a flight.

Abstract:

Potentially damaging operation of a viscous converter clutch (VCC) is detected in relation to the slippage thereacross. The slippage is compared with a reference slip value indicative of excessive VCC slippage to develop a net overslip indicator. The value of the net overslip indicator changes in the direction of a first limit value so long as the detected slip is at least as great as the reference slip, and in the direction of a second limit value so long as the detected slip is less than the reference slip. When the net overslip indicator reaches the first limit value, the friction clutch is disengaged to release the VCC. According to a first embodiment, the transmission fluid temperature at the time of such deactivation is measured and stored, and the VCC is reactivated when transmission fluid temperature falls below the stored temperature, assuming other criteria for activation are also met. According to a second embodiment, the VCC is reactivated a predetermined time after its deactivation and measurement of the transmission fluid temperature is not required.
