Abstract: An improved system and method for performing power management on a distributed system. The system utilized to implement the present invention includes multiple servers for processing a set of tasks. The method of performing power management on a system first determines if the processing capacity of the system exceeds a predetermined workload. If the processing capacity exceeds a predetermined level, at least one of the multiple servers on the network is selected to be powered down and the tasks across the remaining servers are rebalanced. If the workload exceeds a predetermined processing capacity of the system and at least a server in a reduced power state may be powered up to a higher power state to increase the overall processing capacity of the system.

Abstract: Aspects for reporting faults in a redundant power converter are described. An exemplary method aspect includes monitoring at least one node within the redundant power converter. The method further includes tracking values of the at least one node during a predetermined time period, and predicting when a specification of the redundant power converter will be exceeded based on the tracked values.

Abstract: A daughter card is provided with an insertion portion, including a row of contact pads on each side of an edge prepared for insertion into the slot of card edge connector, and a contact structure extending from one or both sides of the card. Contact terminals of the contact structure extend parallel to the insertion portion of the card, being electrically connected to circuits within the card. On a mother board, a connector is provided with a first slot for removably receiving the insertion portion of the daughter card, and with one or two slots for removably receiving the contact terminals. The mother board and the daughter card include essential circuits, which are connected through the contact pads, and non-essential circuits, which are connected through the contact terminals. The daughter card may be plugged into a standard type of card edge connector, having only a single, central card-receiving slot, with the contact terminals extending outside the outer surfaces of the connector.

Abstract: An electronic connector is configured to removably receive either a circuit card of a first type, having one row of contacts per side, on an insertion tab adjacent to an insertion edge, or a circuit card of a second type, having two rows of contacts per side. Two rows of spring contacts are provided for this purpose on each side of a central card-receiving slot. Interposing means are also provided to prevent contact between a daughter card of the first type fully inserted in this slot and one of these rows on each side. These interposing means may consist of a slotted interposer structure slid over a portion of the insertion tab of the card, or alternately of a pair of pivotable interposers mounted along the length of the connector, to be pivoted by sections of daughter cards of the first type so that vanes extending from these interposers will push these springs away from the card.

Abstract: The invention is a software reconfigurable cross point switch which selectively interconnects a plurality of phone lines and a plurality of shared resources such as call progress monitors, dual tone multifrequency (DTMF) receivers, DTMF automatic dialers and automatic answer tone detectors. The invention achieves its objective of enhanced switching efficiency and greater flexibility in the connectivity between diverse communications elements, by independently switching two separate switching planes of the cross point switch so as to enable different paths to be taken by the transmit portion and the receive portion of a particular telephone connection.The cross point switch architecture invention flexibly allows for many applications, one in particular being conference summing.

Abstract: The invention includes a first switch and a second switch serially connected between a telephone network line and a local telephone line which can be selectively connected to alternately either an auto answer modem or a human answer telephone set. A control register is associated with the local telephone line, having data contents representing whether the local telephone line is connected to the auto answer modem or alternately to the human answer telephone set. A billing delay element has an output connected to a control input of the first switch, for delaying the closure of the first switch for a predetermined interval after an answer tone is received over the telephone network line when the control register, which is connected to the control input of the first switch, indicates that the auto answer modem is connected to the local telephone line.
