Abstract: A battery cell tab monitoring apparatus includes a conductive element electrically connected between two battery cells. The conductive element is connected to a sensing circuit including a pull-down current source connected to pull current from the conductive element and/or a pull-up current source connected to drive current into the conductive element. A voltage measuring circuit is connected to sense voltages during operation of the pull-down current source and the pull-up current source to be used to determine the status of the conductive element. For instance, voltages beyond certain fixed or variable thresholds indicate that the conductive element is flexing or cracking, which can be a precursor to its breaking. Voltages beyond other fixed or variable thresholds indicate that the conductive element is fully disconnected. The current sources used to push and pull the sensing currents may be used to bring the battery cells into balance when an imbalance is detected.

Abstract: A method perfomed by an ingress card includes receiving a packet with a destination identifier, and determining an aggregated link associated with the destination identifier that includes multiple egress ports. The method further includes determining a destination port from the egress ports of the aggregated link, and communicating the packet to the destination port.

Abstract: According to one embodiment, processing data packets includes inserting marker packets into a data stream at time intervals. Each marker packet includes a respective first time stamp indicative of the time the marker packet is inserted. An estimate of the age of a data packet is calculated based on a current time system and the respective first time stamp of the last marker packet that was inserted into the data stream before the data packet.

Abstract: The present invention is a method and system which determine signal probability and transfer probability for each node in a netlist describing an electrical circuit; determine, using the signal probability and transfer probability, a fault detection probability for each node; and, using the fault detection probabilities, determine overall fault coverage of the electrical circuit described in the netlist. The method and system of the present invention then, using the fault coverage data, heuristically determine a set of testpoints to be inserted into the netlist which increase the overall fault coverage of the electrical circuit above a predetermined value.
