Abstract: A portable listening device comprising: a device housing defining an internal cavity; an acoustic port formed through the device housing; an audio driver disposed within the device housing and aligned to emit sound through the acoustic port; a multifunction input button coupled to the device housing, the multifunction input button having a distal end and a proximate end, a centerline between the distal and proximate ends and an axis of rotation located between the center line and the proximate end; an electronic circuit disposed within the device housing that requires power to operate and is configured to detect activation of the button; and a battery disposed within the device housing and operable to provide power to the electronic circuit.

Abstract: Described herein are additive manufacturing methods and products made using such methods. The alloy compositions described herein are specifically selected for the additive manufacturing methods and provide products that exhibit superior mechanical properties as compared to their cast counterparts. Using the compositions and methods described herein, products that do not exhibit substantial coarsening, such as at elevated temperatures, can be obtained. The products further exhibit uniform microstructures along the print axis, thus contributing to improved strength and performance. Additives also can be used in the alloys described herein.

Abstract: The disclosure concerns methods for making a composition comprising a light metal and an intermetallic comprising the light metal and a light rare earth element. The composition also may include a plurality of nanoparticles comprising an oxide of the light metal. The method includes directly reducing a light rare earth element precursor compound in a melt of the light metal, thereby forming the light rare earth element and nanoparticles of the light metal oxide.
