Title: Gas insulated electric apparatus
Inventor: ENDO FUMIHIRO
IPC: G01N27/00
Filed: 1991-09-12
Granted: 1996-11-19
Abstract: In a gas insulated electric apparatus having a plurality of gas sections filled with insulating gas, locating device orientates position of a gas section, in which insulation abnormalities are produced, on the basis of a detection signal from sensors disposed in each of predetermined gas sections and at the same time hindering degree diagnosing device diagnoses the degree and the kind of the insulation abnormalities, while comparing a detection signal from the sensors with data stored in a data base. A valve control generates a valve control signal, responding to the locating device and the hindering degree diagnosing device and trip circuit generates a valve opening signal for opening an electromagnetic valve disposed in a gas section, in which insulation abnormalities are produced, responding to this valve control signal.          Insulating gas injecting and evacuating device injects an insulating gas different from the insulating gas, with which the gas sections are filled beforehand, in the gas section, for which the electromagnetic valve opened by the valve opening signal is disposed, or evacuates a predetermined amount of the insulating gas, with which the gas sections are filled beforehand, so as to increase insulation strength.

Title: Method for selectively controlling the propagation of dual tone multi-frequency signals within a telecommunication network
Inventor: PAROLA DARIO LIVIO
IPC: H04M3/42
Filed: 1993-01-26
Granted: 1996-10-01
Abstract: A method for monitoring a network communications channel to detect specific DTMF triggers transmitted by a network user during either a pre-answer or a post-answer period of a call supported by the channel, and, in response to the detected DTMF triggers, controllably prohibiting the propagation of subsequent DTMF signals transmitted over the channel by the network user. Specifically, possible disruption of a communication between the network user and other parties caused by transmission of DTMF signals is eliminated by advantageously transmitting the DTMF triggers during the pre-answer period of a call. Furthermore, another deficiency of prior network-based arrangements for restricting the propagation of DTMF signals is overcome, as the invention may be practiced without the introduction of any significant propagation delay to a network.

Abstract: The voice over data component of a personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site.  This voice over data function directly encodes digitized voice samples onto the carrier using quadrature amplitude modulation to transmit multiple bits of the voice sample for every baud.  The system also allocates selected bauds of the carrier to voice and to data so the voice over data may be transmitted using the same allocated bandwidth. The system may also dynamically reallocate the bandwidth over the telephone line depending on the demands of the voice grade digitized signal.

Granted: 1999-09-21
Abstract: A method of regulating backpressure traffic in a packet switched network made up of a plurality of switching elements each having a local buffer memory identifies at least one switching element which succeeds at least one other switching element in a transmission path. The at least one succeeding switching element has a congested local buffer memory. A backpressure signal is transmitted to the at least one other switching element. Packets destined for the succeedingswitching element are queued in the local buffer memory of the at least one other switching element. Next, it is determined when the occupancy of the local buffermemory for the other switching element has exceeded a predetermined threshold. In response to the exceeded predetermined threshold, the other switching element ignores the backpressure signal transmitted from the succeeding switching element and transmits the queued packets to the succeeding switching element.
