Abstract
Official abstract text for this publication.
An indicator system for an alternating current power bus includes an electret operatively associated with the alternating current power bus. The electret includes an output having an alternating current voltage when the alternating current power bus is energized. A rectifier includes an input electrically interconnected with the output of the electret and an output having a direct current voltage responsive to the alternating current voltage of the output of the electret. An indicator includes an input electrically interconnected with the output of the rectifier and an indication output responsive to the direct current voltage of the output of the rectifier.
First claim
Opening claim text (preview).
What is claimed is: 1. An indicator system for an alternating current power bus, said indicator system comprising: an electret operatively associated with said alternating current power bus, said electret comprising an output having an alternating current voltage when said alternating current power bus is energized with a power bus alternating current voltage; and an indicator comprising: (i) an input wired to the output of said electret such that said input is physically electr…
