A circuit is disclosed for determining which of a multiplicity of LED strings in an illumination system has a fault. A group of circuits determines the maximum, minimum, midpoint between maximum and minimum, and average voltage of the group of LED string voltages in use, and examines the statistical properties of the LED string voltages. Comparators are used to find the strings which have the highest and lowest operating voltages, and to compare the midpoint and average voltages to determine whether the highest or lowest voltage string is responsible for causing a fault in the illumination system operation. Memory means are used to keep the said determined string turned off to prevent faulty operation.

A practical technique for inducing and controlling the fusion of nuclei within a solid lattice. A reactor includes a loading source to provide the light nuclei which are to be fused, a lattice which can absorb the light nuclei, a source of phonon energy, and a control mechanism to start and stop stimulation of phonon energy and / or the loading of reactants. The lattice transmits phonon energy sufficient to affect electron-nucleus collapse. By controlling the stimulation of phonon energy and controlling the loading of light nuclei into the lattice, energy released by the fusion reactions is allowed to dissipate before it builds to the point that it causes destruction of the reaction lattice.
