Abstract: An audio device includes one or more earcups, at least one of the earcups including a boom connector port, a connection detector connected to the boom connector port and configured to detect a connection state at the boom connector port, one or more first microphones positioned in the one or more earcups, audio processing circuitry, and a microphone switch controller connected to the connection detector and configured to connect audio processing circuitry to one of the one or more first microphones or the boom connector port based on the detected connection state of the boom connector port.

Abstract: Wireless earpieces having external antenna features are described. The wireless earpiece can include a housing in which various earpiece componentry is housed. The housing includes a first major surface, a second major surface opposite the first major surface, and various peripheral side wall segments that extend around the first and second major surfaces to thereby form an enclosed housing. The entirety of an anterior portion of the peripheral side wall can serve as the antenna for the wireless earpiece. The entirety of a posterior portion of the peripheral side wall can serve as a grounding element for the wireless earpiece. The grounding element can also extend to include portions of the inferior and superior portions of the peripheral side wall.

Abstract: A simple, compact process for cleansing hydrocarbon fuel such as jet fuel is disclosed. This process involves subjecting the fuel to an oxidative desulfurization process in a desulfurization reactor followed by passing the fuel through an adsorption bed. The cleansed desulfurized fuel may then be utilized directly in generation of hydrogen for fuel cell applications.
