Abstract: A dual cone speaker unit with an analog speaker and a separate internet protocol speaker in a single housing. The analog speaker may generally be configured to be UL-1480 Code compliant and may be configured to be used in a public notification system that is designed for evacuation, fire notification, and other emergency communications. The disclosed dual cone speaker system improves existing analog speaker systems and internet protocol speaker systems by eliminating the need for a separate housing for the two speakers, which reduces installation time and labor by reducing the mounting hardware, wiring, and holes to be made in the walls of the facility.

Abstract: An apparatus for providing a simple, low-frequency electrodeless discharge system for atmospheric pressure afterglow generation. A single quartz tube through which a gas mixture is passed is extended beyond a concentric electrode positioned thereabout. A grounding rod is placed directly above the tube outlet to permit optical viewing of the discharge between the electrodes.
