Abstract: An interrupter device for controlling provision of grid power to its output terminals is adapted to sense, using low voltage, electrical parameters measurable between its output terminals and connect or avoiding connection of AC power to the output terminals based on the sensed parameters. The interrupter device is adapted to identify if any load is connected to the output terminals, whether that load is a living tissue, whether the load may pose too-high load or has ground-fault.

Abstract: A method for detecting a dispersed pulse in a received signal that has been dispersed by a dispersive medium includes obtaining an input array of cells, each indicating an intensity of a frequency component of the signal at a representative time. A fast dispersion measure transform (FDMT) is applied to concurrently sum the cells of the input array that lie along different dispersion curves, each curve defined by a known non-linear functional form and being uniquely characterized by a time coordinate and by a value of the dispersion measure. Application of FDMT includes initially generating a plurality of sub-arrays, each representing a frequency sub-band and iteratively combining pairs of adjacent sub-arrays in accordance with an addition rule until all of the initially generated plurality of sub-arrays are combined into an output array of the sums, in which a cell of the output array that is indicative of a transmitted pulse is identified.
