Abstract: A system for a tag includes a network controller that, when it has information to send to a tag, is configured to communicate with the tag's neighbors, such as anchors that may be used for communication between the tag and the network controller. In this regard, the network controller may instruct the tag's neighbors to stun the tag upon hearing from the tag. Thus, when the tag transitions out of a sleep state and transmits a status message or other type of message to the network controller or other resource of the network, at least one neighbor of the tag hears the message and, in response, stuns the tag so that it remains awake for a longer period of time, thereby giving the network controller sufficient time to send control information or other information to the tag. Since the neighbors are responsible for stunning the tag, the amount of time required to stun the tag after it awakens from the sleep state is decreased.

Abstract: A monitoring system for a facility can automatically determine the presence of leaks in a compressed gas system at the facility. The monitoring system can use information from sensors in the compressed gas system to determine if there is a constant flow of gas in the system that can be indicative of a leak in the system. The monitoring system can process flow measurements from the sensors to determine minimum gas flow amounts for a series of time windows. The minimum gas flow amounts are then averaged to generate an average minimum gas flow amount. If the average minimum gas flow amount is greater than an average threshold, a variance of the minimum gas flow amounts can be determined. If the determined variance is less than a variance threshold, the average minimum gas flow amount is determined to correspond to a leak in the compressed gas system.

Abstract: A communications session call is established between first and second call devices. A SIP Reinvite command is sent to the second call device without any SDP media parameters to gain new and current media parameters. The second call device acknowledges the Reinvite command as corresponding to the first SDP offer with new and current media parameters. A third call device is sent a SIP Reinvite command as a second SDP offer using new and current media parameters. The third call device acknowledges the SIP Reinvite command as corresponding to the first SDP answer to the first SDP offer. The second call device acknowledges as a second SDP answer to the second SDP offer. The call with the first call device is terminated to change the destination of the call and maintaining any media stream between the second and third call devices.

Abstract: A network element has at least one receiver, a software queue, and at least one transmitter. A data path thread moves data packets from a receive queue of the receiver to the software queue, and a transmit driver moves data packets from the software queue to a transmit queue of the transmitter. A flow indicator associated with the software queue is controlled to indicate when at least one data packet remains in the software queue. A queue management thread polls the flow indicator to determine when the software queue should be accessed for ensuring that data packets do not remain in the software queue for extended time periods between data bursts.

Abstract: Hardware and resource usage penalties associated with the conventional remote device management approach of occupying a robbed DS0 channel for only one management session at a time are obviated by programming a multi-digital circuit servicing host site-resident integrated access device to provide for effective simultaneous management of multiple remote digital communication devices by one or more workstations. Although only a single robbed in-band (T1) channel per remote site is used, it is unnecessary to terminate each high speed digital (T1) link with an associated T1 Service Unit and ISDN Service Unit pair at the central office site.
