Abstract: An audio monitoring system for an audio performance consists of one or more terminal units and one or more base units. The base units are configured to send transmission data consisting of channel labels, frequencies, and mix identifiers to the terminal units. The terminal units are configured to receive and store the transmission data. The terminal units permit a user to select the stored transmission data and to display the transmission data on a user display. The terminal units can receive audio signals from the base units over the stored frequencies and are configured to output the corresponding audio signals to a sound transmission device.

Abstract: The present invention provides for a system and process for enhancing internal combustion engine aftertreatment applications by superheated fuel injection. The system includes a fuel supply upstream of a fuel injector of an aftertreatment application. The system also includes a heater for heating the fuel in the fuel supply. A temperature controller can be used to maintain the heated fuel in a liquid form. When liquid fuel in the pressurized fuel supply is heated, then upon exiting the injector the pressure of the fuel drops rapidly, resulting in atomization of the liquid. The vaporized fuel thereby produced is comprised of extremely small droplets and is elevated in temperature, which reduces the possibility of condensation on internal surfaces of the aftertreatment system. This fine droplet size and resistance to condensation enhances the NOx conversion efficiency of adsorbers. Problems related to premature aging of catalysts and fuel penalties can also be reduced.
