摘要: Improved modular transient voltage surge suppressor apparatus are disclosed that equalize transient current sharing between multiple modules. In general, such apparatus includes first and second transient voltage surge suppression modules, each module having a non-conductive housing with a surge suppression circuit contained therein, and first and second electrically-conductive buses mechanically coupled to the non-conductive housing and electrically coupled to first and second terminals of the surge suppression circuit, respectively. A first bus coupler couples the first electrically-conductive buses of the first and second transient voltage surge suppression modules and a second bus coupler couples the second electrically-conductive buses of the first and second transient voltage surge suppression modules, whereby the surge suppression circuits in each of the first and second modules are electrically coupled in parallel. A first electrical conductor coupler is electrically coupled to, and physically located proximate, the first electrically-conductive bus of the first transient voltage surge suppression module, and a second electrical conductor coupler is electrically coupled to, and physically located proximate, the second electrically-conductive bus of the second transient voltage surge suppression module, whereby the electrical path length from the first electrical conductor coupler to the second electrical conductor coupler and through the surge suppression circuit of the first transient voltage surge suppression module is substantially equal to the electrical path length from the first electrical conductor coupler to the second electrical conductor coupler and through the surge suppression circuit of the second transient voltage surge suppression module.

摘要: According to one embodiment of the present invention, a method of displaying an image includes alternating an active state of each of a plurality of light sources. The light sources each generate a light beam when active. The alternating includes deactivating an active light source before an output of a light beam from the active light sources falls below a first predetermined threshold. The alternating further includes activating an inactive light source only after an output of the inactive light source reaches a second predetermined threshold. The method further includes receiving each of the light beams at a modulator. The modulator includes an array of micro-mirror devices.
