Abstract: In the past, in electrical power networks, the effects on the system of particular contingencies, such as interruption of a power line, have been modelled off-line. Such models have generally been overly conservative, adding considerable cost to power systems. The present invention provides an on-line method of transient stability assessment referred to as the "second kick" method. It does this by providing a computer model of the system, simulating a study contingency, measuring the effect on the energy properties in the system of the study contingency, and if instability is indicated, calculating the transient energy margin from the corrected kinetic energy and, if the measured energy properties indicate stability introducing an artificial contingency into the model which is of sufficient duration to make this system unstable and measuring the transient energy margin as the difference between the corrected kinetic energy after the artificial contingency and the minimum value of the corrected kinetic energy after the artificial contingency, after compensating for the potential energy change introduced into the system by the artificial contingency.

Abstract: A system and method for generating a signal having a reliable, fixed duration and/or delay as a function of relative, not absolute, device characteristics. That is to say, the time period of the generated signal is determined as a ratio of one device's operating characteristics to another device's operating characteristics. In particular, the invention provides a fixed time signal as a function of the relative values of two capacitive elements that have a known ratio of capacitance with respect to each other. The invention is particularly useful when implemented upon an integrated circuit, as standard fabrication techniques for such circuits allow relative device characteristics to be held to relatively tight tolerances.

Abstract: Quantitative measurement of corneal surface topography is obtained by processing a two-dimensional image of the surface (6) which reflects a quasi-periodic illuminated pattern, such as a series of concentric rings (13), from a Placido disk source. The local spatial phases exhibited by the image of the illuminated pattern when reflected from the corneal surface and when reflected from standard specular surfaces are obtained by processing the images (42). The distances at which predetermined local spatial phases are observed in the image from the cornea are compared (42) with the distances at which these same phases are observed in the images of the standard surfaces. The distances are also compared (42) with certain corresponding distances on the source and converted to reveal the dioptric powers of refraction of the corneal surface without the need for parametric interpolation. During processing, any mislocation of the apex of the corneal surface along the optical axis is compensated for.
