Data is structured with information indicative of time-related, bandwidth-related, or class-related quality-of-service (QoS) required for sending the data so that a receiving terminal or any network element processing the data in transit over a network is able to determine whether the required quality-of-service has actually been uniformly experienced by the data and, in case the quality-of-service is degraded in any section of the network, the receiving terminal or the network element is able to cause the network to either uniformly accord to the data a degraded quality-of-service corresponding to that actually experienced or to actually uniformly provide the required quality-of-service between the sending and receiving terminals by improving the processing of the data by the network element or elements. A corresponding method, apparatus, system and computer programs are shown.

An apparatus and method provide protection for a synchronous generator in a power system. The method includes deriving a plurality of generator safe operating boundary data expressions from power system data and / or user-defined inputs. The power system data may include a plurality of generator data supplied by a manufacturer of the generator and / or power system parameters such as power system equivalent impedance. Each generator safe operating boundary data expression may relate to a generator capability curve, a steady-state stability limit curve, a minimum excitation limiter curve, an over excitation limiter curve, or an user-defined curve. The method also includes calculating an active power value sum and a reactive power value sum based on generator three-phase currents and voltages, comparing these sums to at least one of the plurality of generator safe operating boundary data expressions, and to provide protection and / or alarming functions for the generator based on this comparison.

An improved system and method are disclosed for facilitating target aiming and aircraft control by flight crews using electronic displays. For example, an aircraft display system is disclosed that includes a database for storing target location and boundary data, a processing unit, a position and direction determination unit for use in determining the position of an aiming symbol on a display, a graphics display generator, and a visual display. The processing unit determines whether or not a selected target to be displayed is obscured or covered by the aiming symbol to be displayed. If any portion of the target is obscured or covered by the aiming symbol, then the processing unit directs the graphics display generator to generate graphic control signals for the visual display, which increase the transparency of the portions of the aiming symbol that obscure or cover the target. Notably, the transparency of any symbol (or portion of a symbol) can be increased if that symbol obscures or covers a target being displayed or viewed. Thus, the visibility of targets viewed using onboard visual displays is significantly enhanced, whereby the targets are obscured by the symbols used to aim and control the aircraft. Advantageously, target aiming and aircraft control are facilitated, which reduces pilot workload and navigation errors, and thus results in increased aircraft safety.

A system for monitoring and / or controlling tissue modification during an electrosurgical procedure is provided. The system includes an electrosurgical apparatus adapted to connect to an electrosurgical generator. The electrosurgical apparatus configured to transmit energy to tissue. The system also includes a control system having one or more electromagnetic wave sources configured to generate the interrogator wave of one or more frequencies adjacent tissue. One or more sensors are configured to transmit and sense a reflected portion of the interrogator wave of at least one frequency to determine dielectric boundary data. A processor operatively coupled to the control system and to the electrosurgical generator configured to control the delivery of electrosurgical energy from the electrosurgical generator to tissue based on dielectric boundary data provided by the one or more sensors.
