Abstract: Dual-tone horn assemblies and methods of use are disclosed herein. An example dual scroll assembly includes a nozzle having a first portion of the nozzle has a first diameter and a second portion of the nozzle has a second diameter that has a size that is different from the first diameter, a first spiraled channel that receives air from the first portion of the nozzle. The air traveling through the first spiraled channel produces a first tone at a first frequency. A divider plate is disposed between the first spiraled channel and a second spiraled channel. The second spiraled channel receives the air from the second portion of the nozzle. The air traveling through the second spiraled channel produces a second tone at a second frequency. The first tone and the second tone when produced simultaneously create a dyad.

Abstract: A vehicle inverter is arranged to transform direct current power from a power supply to alternating current power for an outlet. The inverter includes a transformer electrically connected between the power supply and outlet, a resistive element that can be selectively electrically connected in parallel with the transformer via a multiway switch to establish a direct electrical connection between the power supply and outlet, and a controller that selectively commands the multiway switch to close according to values indicative of resistance between the power supply and outlet before and after the multiway switch is closed.
